Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/

You need to add the package containing the executable pg_config.

A prior answer should have details you need: pg_config executable not found

See This Image and Add This line in your android AndroidManifest.xml

tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"

Try this:

implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'

First Rename your AndroidManifest.xml file

android:label="Your App Name"

Second Rename Your Application Name in Pubspec.yaml file name: Your Application Name

Third Change Your Application logo

flutter_icons:
   android: "launcher_icon"
   ios: true
   image_path: "assets/path/your Application logo.formate"

Fourth Run

flutter pub pub run flutter_launcher_icons:main

i got the same bug, and i fixed it when i close the AndroidStudio and delete the dir like C:\Users\Jalal D\.gradle\caches\transforms-1\ in the build error info.

I had this same issue on Windows 10. I bypassed it by running the Docker daemon in experimental mode:

1. Right click Docker icon in the Windows System Tray
2. Go to Settings
3. Daemon
4. Advanced
5. Set the "experimental": true
6. Restart Docker

Inside your .idea folder, change workspace.xml file

Add

<property name="dynamic.classpath" value="true" />

to

  <component name="PropertiesComponent">
.
.
.
  </component>

Example

 <component name="PropertiesComponent">
    <property name="project.structure.last.edited" value="Project" />
    <property name="project.structure.proportion" value="0.0" />
    <property name="project.structure.side.proportion" value="0.0" />
    <property name="settings.editor.selected.configurable" value="preferences.pluginManager" />
    <property name="dynamic.classpath" value="true" />
  </component>

If you don't see one, feel free to add it yourself

 <component name="PropertiesComponent">
    <property name="dynamic.classpath" value="true" />
  </component>

I found slimier problem. Please import the HttpClientModule in your app.module.ts file as follow:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';
import { HttpClientModule } from '@angular/common/http';

@NgModule({
  declarations: [
    AppComponent
],

imports: [
    BrowserModule,
    HttpClientModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

I am using Android Studio 3.0 and was facing the same problem. I add this to my gradle:

multiDexEnabled true

And it worked!

Example

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.1'
    defaultConfig {
        applicationId "com.xx.xxx"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        multiDexEnabled true //Add this
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

And clean the project.

I got the same error. In my case, I was using a mapped drive to edit code off of a second computer, that computer was running linux. Not sure exactly why gulp-watch relies on operating system compatibility prior to install (I would assume it has to do with security purposes). Essentially the error is checking against your operating system and the operating system calling the node module, in my case the two operating systems were not the same so it threw it error. Which from the looks of your error is the same as mine.

The Error

Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

How I fixed it?

I logged into the linux computer directly and ran

npm install --save-dev <module-name>

Then went back into my coding environment and everything was fine after that.

Hope that helps!

In my case that URL is not working in browser also.

I check with https://www.google.com/

webView.loadUrl("https://www.google.com/")

And it worked for me.

The guide you linked now has a Tear Down section:

Talking to the master with the appropriate credentials, run:

kubectl drain <node name> --delete-local-data --force --ignore-daemonsets
kubectl delete node <node name>

Then, on the node being removed, reset all kubeadm installed state:

kubeadm reset

If you use React Native

This problem has been completely solved here

https://facebook.github.io/react-native/docs/removing-default-permissions

I also had this same problem.

I build .apk file of the project and installed it into mobile(android) and got it working

check this code from MainActivity

 // Check location permission is granted - if it is, start
// the service, otherwise request the permission
fun checkOrAskLocationPermission(callback: () -> Unit) {
    // Check GPS is enabled
    val lm = getSystemService(Context.LOCATION_SERVICE) as LocationManager
    if (!lm.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
        Toast.makeText(this, "Please enable location services", Toast.LENGTH_SHORT).show()
        buildAlertMessageNoGps(this)
        return
    }

    // Check location permission is granted - if it is, start
    // the service, otherwise request the permission
    val permission = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
    if (permission == PackageManager.PERMISSION_GRANTED) {
        callback.invoke()
    } else {
        // callback will be inside the activity's onRequestPermissionsResult(
        ActivityCompat.requestPermissions(
            this,
            arrayOf(Manifest.permission.ACCESS_FINE_LOCATION),
            PERMISSIONS_REQUEST
        )
    }
}

plus

   override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults)
    if (requestCode == PERMISSIONS_REQUEST) {
        if (grantResults[0] == PackageManager.PERMISSION_GRANTED){
              // Permission ok. Do work.
         }
    }
}

plus

 fun buildAlertMessageNoGps(context: Context) {
    val builder = AlertDialog.Builder(context);
    builder.setMessage("Your GPS is disabled. Do you want to enable it?")
        .setCancelable(false)
        .setPositiveButton("Yes") { _, _ -> context.startActivity(Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS)) }
        .setNegativeButton("No") { dialog, _ -> dialog.cancel(); }
    val alert = builder.create();
    alert.show();
}

usage

checkOrAskLocationPermission() {
            // Permission ok. Do work.
        }

If you add the android:theme="@style/Theme.AppCompat.Light" to <application> in AndroidManifest.xml file, problem is solving.

You can download the wheel corresponding to your configuration here ("Pillow-4.1.1-cp36-cp36m-win_amd64.whl" in your case) and install it with:

pip install some-package.whl

If you have problem to install the wheel read this answer

I got the same issue while adding dynamic url in Image tag in Angular 7. I searched a lot and found this solution.

First, write below code in the component file.

constructor(private sanitizer: DomSanitizer) {}
public getSantizeUrl(url : string) {
    return this.sanitizer.bypassSecurityTrustUrl(url);
}

Now in your html image tag, you can write like this.

<img class="image-holder" [src]=getSantizeUrl(item.imageUrl) />

You can write as per your requirement instead of item.imageUrl

I got a reference from this site.dynamic urls. Hope this solution will help you :)

First check if the user has granted the permission:

if (ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA)
    == PackageManager.PERMISSION_DENIED)

Then, you could use this to request to the user:

ActivityCompat.requestPermissions(activity, new String[] {Manifest.permission.CAMERA}, requestCode);

And in Marshmallow, it will appear in a dialog

If you are running in Android 29 then you have to use scoped storage or for now, you can bypass this issue by using:

android:requestLegacyExternalStorage="true"

in manifest in the application tag.

you want to work onMessageReceived(RemoteMessage remoteMessage) in background send only data part notification part this:

"data":    "image": "",    "message": "Firebase Push Message Using API", 

"AnotherActivity": "True", "to" : "device id Or Device token"

By this onMessageRecivied is call background and foreground no need to handle notification using notification tray on your launcher activity. Handle data payload in using this:

  public void onMessageReceived(RemoteMessage remoteMessage)
    if (remoteMessage.getData().size() > 0) 
    Log.d(TAG, "Message data payload: " + remoteMessage.getData());      

If anyone facing similar type of error while adding ShimmerRecyclerView Loader in android , make sure to add maven { url "https://jitpack.io" } under allprojects like below.

    allprojects {
    repositories {
        google()
        jcenter()
        //add it here
        maven { url "https://jitpack.io" }
      }
   }

I found my answer! I looked into the pom for any plugins that have a dependency on the maven-archiver and found the maven-jar-plugin does. It was using the latest 3.0.0 version. When I downgraded to 2.6 it seems to fix the issue :-)

I've used the react-native-rename package.

In terminal run the command to install:

npm install react-native-rename -g

In the root of your React Native project, run the following command:

react-native-rename "NewNameOfApp" -b com.companyname.newnameofapp

I faced the same issue of Firebase cloud messaging not received by device.

In my case package name defined on Firebase Console Project was diferent than that the one defined on Manifest & Gradle of my Android Project.

As a result I received token correctly but no messages at all.

To sumarize, it's mandatory that Firebase Console package name and Manifest & Gradle matchs.

You must also keep in mind that to receive Messages sent from Firebase Console, App must be in background, not started neither hidden.

In my case the problem happened after we migrated to AndroidX. For some reason, app was calling MultiDex.install() with reflection:

    final Class<?> clazz = Class.forName("android.support.multidex.MultiDex");
    final Method method = clazz.getDeclaredMethod("install", Context.class);
    method.invoke(null, this);

I changed package from android.support.multidex.MultiDex to androidx.multidex.MultiDex. It worked.

Despite all the other great answers none helped me until I found a comment that pointed out this Updating images:

The default pull policy is IfNotPresent which causes the kubelet to skip pulling an image if it already exists.

That's exactly what I wanted, but didn't seem to work.

Reading further said the following:

If you would like to always force a pull, you can do one of the following:

• omit the imagePullPolicy and use :latest as the tag for the image to use.

When I replaced latest with a version (that I had pushed to minikube's Docker daemon), it worked fine.

$ kubectl create deployment presto-coordinator \
    --image=warsaw-data-meetup/presto-coordinator:beta0
deployment.apps/presto-coordinator created

$ kubectl get deployments
NAME                 READY   UP-TO-DATE   AVAILABLE   AGE
presto-coordinator   1/1     1            1           3s

Find the pod of the deployment (using kubectl get pods) and use kubectl describe pod to find out more on the pod.

In my case -- I am running Visual Studio (Professional 2017) in debug mode with webpack 2.4.1 -- it was necessary to put the favicon.ico into the root directory of the project, right where the folder src is rather than in a folder public, even though according to https://create-react-app.dev/docs/using-the-public-folder the latter should be the official location.

For Unity Game Developers

**

If anyone comes here because this error showed up in their Unity project, Go to File->Build Settings -> Player Settings -> Player. go to Publishing Settings and under the Build tab, enable "Custom Launcher Gradle Template". a path will be shown under that text. go to the path and add multiDexEnabled true like this:

defaultConfig {
    minSdkVersion **MINSDKVERSION**
    targetSdkVersion **TARGETSDKVERSION**
    applicationId '**APPLICATIONID**'
    ndk {
        abiFilters **ABIFILTERS**
    }
    versionCode **VERSIONCODE**
    versionName '**VERSIONNAME**'
    multiDexEnabled true
}

surefire plugins version might be one of the reasons. For me following dependency worked. Please try:

    <!-- https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-surefire-plugin -->
<dependency>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.19.1</version>
</dependency>

Another possible reason

resConfigs "hdpi", "xhdpi", "xxhdpi", "xxxhdpi"

can be source of this issue

You can try:

<activity android:name=".YourActivityName"
          android:theme="@style/Theme.Design.NoActionBar">

that works for me

open key.properties and check your path is correct. (replace from \ to /)

example:-

replace from "storeFile=D:\Projects\Flutter\Key\key.jks" to "storeFile=D:/Projects/Flutter/Key/key.jks"

In my case after invalidate cache and restart the android studio fixed the problem .To do that go to

File -> invalidate cache / Restart

In my case my application tag includes:

 <application
    android:name=".common.MyApplication"
    android:allowBackup="false"
    android:extractNativeLibs="false"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    android:usesCleartextTraffic="true"
    tools:ignore="GoogleAppIndexingWarning"
    tools:replace="android:appComponentFactory">

I resolved this issue my adding new param as android:appComponentFactory=""

So my final application tag becomes:

<application
    android:name=".common.MyApplication"
    android:allowBackup="false"
    android:extractNativeLibs="false"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    android:usesCleartextTraffic="true"
    tools:ignore="GoogleAppIndexingWarning"
    tools:replace="android:appComponentFactory"
    android:appComponentFactory="">

I encountered above issue when I tired using firebase-auth latest version as "19.3.1". Whereas in my project I was already using firebase but version was "16.0.6".

I had a need to request permission for WRITE_EXTERNAL_STORAGE but was not getting a pop-up despite trying all of the different suggestions mentioned.

The culprit in the end was HockeyApp. It uses manifest merging to include its own permission for WRITE_EXTERNAL_STORAGE except it applies a max sdk version onto it.

The way to get around this problem is to include it in your Manifest file but with a replace against it, to override the HockeyApp's version and success!

4.7.2 Other dependencies requesting the external storage permission (SDK version 5.0.0 and later) To be ready for Android O, HockeySDK-Android 5.0.0 and later limit the WRITE_EXTERNAL_STORAGE permission with the maxSdkVersion filter. In some use cases, e.g. where an app contains a dependency that requires this permission, maxSdkVersion makes it impossible for those dependencies to grant or request the permission. The solution for those cases is as follows:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" tools:node="replace"/>

It will cause that other attributes from low priority manifests will be replaced instead of being merged.

https://support.hockeyapp.net/kb/client-integration-android/hockeyapp-for-android-sdk#permissions-advanced

this is your code

ContactListActivityBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_contact_list);

Replace this code

ActivityMainBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_contact_list);

Open google-services.json in android studio we can see a json object, and contain following items in 'client' jsonarray

"client_id": "android:your package name", "package_name": "your package name",

Please verify your package and proceed.

Firstly make sure your API Key is valid and add this into your manifest <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

There's a lot of methods here that are hard to understand but basically all update the map when it's paused etc. There are also connection timeouts etc. Sorry for just posting this, I tried to fix your code but I couldn't figure out what was wrong.

You can remove the warning by adding the below code in <intent-filter> inside <activity>

<action android:name="android.intent.action.VIEW" />

I found in my case, this issue was caused by an improper configuration of build.gradle. I had two different versions of com.google.firebase. Once the versions were the same, the issue was solved

You can use Dexter

In build.gradle add:

implementation 'com.karumi:dexter:5.0.0'

And use it in your activity as:

val requiredPermissions = when {
            Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q -> listOf(Manifest.permission.ACCESS_FINE_LOCATION,
                Manifest.permission.ACCESS_COARSE_LOCATION,
                Manifest.permission.ACCESS_BACKGROUND_LOCATION)
            else -> listOf(Manifest.permission.ACCESS_FINE_LOCATION,
                Manifest.permission.ACCESS_COARSE_LOCATION)
        }

Dexter.withActivity(this)
     .withPermissions(
           requiredPermissions
      )
     .withListener(object : MultiplePermissionsListener {
        override fun onPermissionRationaleShouldBeShown(
             permissions: MutableList<PermissionRequest>?,
                    token: PermissionToken?
             ) {
                    /* ... */
                }


        override fun onPermissionsChecked(report: MultiplePermissionsReport) = 
             if (report.isAnyPermissionPermanentlyDenied) {
                toast("You should grant all permissions") 
             } else {
                toast("All permissions granted")

                // continue here if permission is a must

              }).check()

             // continue here if permission is not a must

You need to install C compiler, C/C++ extension, configure launch.json and tasks.json to be able to debug C code.

This article would guide you how to do it: https://medium.com/@jerrygoyal/run-debug-intellisense-c-c-in-vscode-within-5-minutes-3ed956e059d6

I just had to delete and reinstall my google-services.json and then restart Android Studio.

Here is the method you can use to get header view and set data accourdingly

val headerView: View? = navigationView.getHeaderView(0) // Index of the added headerView  

// Now you can access child views of the header view
val titleTextView: TextView? = headerView?.findViewById(R.id.titleTextView)

Before starting your download check your runtime permissions and if you don't have permission the request permissions like this method

requestStoragePermission()

private void requestStoragePermission(){
    if (ActivityCompat.shouldShowRequestPermissionRationale(this, 
                android.Manifest.permission.READ_EXTERNAL_STORAGE))
        {

        }

        ActivityCompat.requestPermissions(this, 
            new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
            STORAGE_PERMISSION_CODE);
}

@Override
public void onRequestPermissionsResult(int requestCode, 
                @NonNull String[] permissions, 
                @NonNull int[] grantResults) {

    if(requestCode == STORAGE_PERMISSION_CODE){
        if(grantResults.length >0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
        }
        else{
            Toast.makeText(this,
                           "Oops you just denied the permission", 
                           Toast.LENGTH_LONG).show();
        }
    }
}

Right. So I've finally got to the bottom of the problem: it was a botched in-place OTA upgrade.

My suspicions intensified after my Garmin Fenix 2 wasn't able to connect via bluetooth and after googling "Marshmallow upgrade issues". Anyway, a "Factory reset" fixed the issue.

Surprisingly, the reset did not return the phone to the original Kitkat; instead, the wipe process picked up the OTA downloaded 6.0 upgrade package and ran with it, resulting (I guess) in a "cleaner" upgrade.

Of course, this meant that the phone lost all the apps that I'd installed. But, freshly installed apps, including mine, work without any changes (i.e. there is backward compatibility). Whew!

Are you running Android M? If so, this is because it's not enough to declare permissions in the manifest. For some permissions, you have to explicitly ask user in the runtime: http://developer.android.com/training/permissions/requesting.html

I had a similar problem except I was pressing a button to make a call, which triggers the callIntent. I checked permission first, if not granted I ask for permission and onRequestPermissionResult I call the check permission and call again.

 @Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case Constants.PERMISSIONS_REQUEST_CALL_PHONE: {
            if ( grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                checkPermissionsAndCall();
            }
        }
    }
}

public void checkPermissionsAndCall(){
    if (Build.VERSION.SDK_INT > 22) {
        if(ContextCompat.checkSelfPermission(getContext(),
                Manifest.permission.CALL_PHONE)
                != PackageManager.PERMISSION_GRANTED){
            requestPermissions( new String[]{Manifest.permission.CALL_PHONE}, Constants.PERMISSIONS_REQUEST_CALL_PHONE);
        }
        else{
            callIntent();
        }
    }
}

The last part of the error message you quoted states: ...with ("checkPermission") or explicitly handle a potential "SecurityException"

A much quicker/simpler way of checking if you have permissions is to surround your code with try { ... } catch (SecurityException e) { [insert error handling code here] }. If you have permissions, the 'try' part will execute, if you don't, the 'catch' part will.

Please Check below code that using that You can find all Music Files from sdcard :

public class MainActivity extends Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_animations);
    getAllSongsFromSDCARD();

}

public void getAllSongsFromSDCARD() {
    String[] STAR = { "*" };
    Cursor cursor;
    Uri allsongsuri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
    String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";

    cursor = managedQuery(allsongsuri, STAR, selection, null, null);

    if (cursor != null) {
        if (cursor.moveToFirst()) {
            do {
                String song_name = cursor
                        .getString(cursor
                                .getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
                int song_id = cursor.getInt(cursor
                        .getColumnIndex(MediaStore.Audio.Media._ID));

                String fullpath = cursor.getString(cursor
                        .getColumnIndex(MediaStore.Audio.Media.DATA));

                String album_name = cursor.getString(cursor
                        .getColumnIndex(MediaStore.Audio.Media.ALBUM));
                int album_id = cursor.getInt(cursor
                        .getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));

                String artist_name = cursor.getString(cursor
                        .getColumnIndex(MediaStore.Audio.Media.ARTIST));
                int artist_id = cursor.getInt(cursor
                        .getColumnIndex(MediaStore.Audio.Media.ARTIST_ID));
                System.out.println("sonng name"+fullpath);
            } while (cursor.moveToNext());

        }
        cursor.close();
    }
}


}

I have also added following line in the AndroidManifest.xml file as below:

<uses-sdk
    android:minSdkVersion="16"
    android:targetSdkVersion="17" />

<uses-permission android:name="android.permission.MEDIA_CONTENT_CONTROL" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

I tried my best to try all the examples available for this issue. Finally I got the answer for this I don know how much is it reliable but my app is not crashing now.

windowManager = (WindowManager)getSystemService(WINDOW_SERVICE);
    //here is all the science of params
    final LayoutParams myParams = new LayoutParams(
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.WRAP_CONTENT,
            LayoutParams.TYPE_SYSTEM_ERROR,
            WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                    | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
                    | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
            PixelFormat.TRANSLUCENT
    );

In your manifest file just give the permission

 <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

Addition to this you can also check for the API level if its >=23 then

 if(Build.VERSION.SDK_INT >= 23) {
    if (!Settings.canDrawOverlays(Activity.this)) {
        Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
                Uri.parse("package:" + getPackageName()));
        startActivityForResult(intent, 1234);
    }
}
            else
{
    Intent intent = new Intent(Activity.this, Service.class);
    startService(intent);
}

I hope it helps someone somewhere. Full example https://anam-android-codes.blogspot.in/?m=1

My simple solution is this

if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) ==
        PackageManager.PERMISSION_GRANTED &&
        ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) ==
        PackageManager.PERMISSION_GRANTED) {
    googleMap.setMyLocationEnabled(true);
    googleMap.getUiSettings().setMyLocationButtonEnabled(true);
} else {
    Toast.makeText(this, R.string.error_permission_map, Toast.LENGTH_LONG).show();
}

or you can open permission dialog in else like this

} else {
   ActivityCompat.requestPermissions(this, new String[] {
      Manifest.permission.ACCESS_FINE_LOCATION, 
      Manifest.permission.ACCESS_COARSE_LOCATION }, 
      TAG_CODE_PERMISSION_LOCATION);
}

It could be that something else is running on port 8080, and you're actually connecting to it by mistake.

Definitely check that out, especially if you have dockers that are bringing up other services you don't control, and are port forwarding those services.

1. update your version of youtube-dl to the lastest as older version might not support palylists.

   sudo youtube-dl -U if u installed via .deb

   sudo pip install --upgrade youtube_dl via pip

2. use this to download the playlist as an MP3 file

   youtube-dl --extract-audio --audio-format mp3 #url_to_playlist

I fixed this issue by moving the project to the outer directory, and it then compiled successfully.

It was due to the long path of the project directory.

For example, I moved the project from:

D:/Android/Apps/AndroidStudioProject/AppName

to

D:/Android/AppName

This is my take on expanding @klimat answer to not losing filtering animation.

public void filter(String query){
    int completeListIndex = 0;
    int filteredListIndex = 0;
    while (completeListIndex < completeList.size()){
        Movie item = completeList.get(completeListIndex);
        if(item.getName().toLowerCase().contains(query)){
            if(filteredListIndex < filteredList.size()) {
                Movie filter = filteredList.get(filteredListIndex);
                if (!item.getName().equals(filter.getName())) {
                    filteredList.add(filteredListIndex, item);
                    notifyItemInserted(filteredListIndex);
                }
            }else{
                filteredList.add(filteredListIndex, item);
                notifyItemInserted(filteredListIndex);
            }
            filteredListIndex++;
        }
        else if(filteredListIndex < filteredList.size()){
            Movie filter = filteredList.get(filteredListIndex);
            if (item.getName().equals(filter.getName())) {
                filteredList.remove(filteredListIndex);
                notifyItemRemoved(filteredListIndex);
            }
        }
        completeListIndex++;
    }
}

Basically what it does is looking through a complete list and adding/removing items to a filtered list one by one.

Add an onChange handler to each of your TextField and DropDownMenu elements. When it is called, save the new value of these inputs in the state of your Content component. In render, retrieve these values from state and pass them as the value prop. See Controlled Components.

var Content = React.createClass({

    getInitialState: function() {
        return {
            textFieldValue: ''
        };
    },

    _handleTextFieldChange: function(e) {
        this.setState({
            textFieldValue: e.target.value
        });
    },

    render: function() {
        return (
            <div>
                <TextField value={this.state.textFieldValue} onChange={this._handleTextFieldChange} />
            </div>
        )
    }

});

Now all you have to do in your _handleClick method is retrieve the values of all your inputs from this.state and send them to the server.

You can also use the React.addons.LinkedStateMixin to make this process easier. See Two-Way Binding Helpers. The previous code becomes:

var Content = React.createClass({

    mixins: [React.addons.LinkedStateMixin],

    getInitialState: function() {
        return {
            textFieldValue: ''
        };
    },

    render: function() {
        return (
            <div>
                <TextField valueLink={this.linkState('textFieldValue')} />
            </div>
        )
    }

});

For me the problem was nothing to do with Maven but to do with how I was running the .jar. I wrote some code and packaged it as a .jar with Maven. I ran it with

java target/gs-maven-0.1.0.jar

and got the error in the OP. Actually you need the -jar option:

java -jar target/gs-maven-0.1.0.jar

After adding a jar file to a project's lib folder and after adding it to the build.gradle file as compile'path example' when you sync the gradle it add an additional line as compile files('libs/example.jar'). You just need to remove the line you previously added to the build.gradle file i.e. the compile'path example' after the gradle sync. You also need to remove the line compile fileTree(dir: 'libs', include: '*.jar')

In my case I had installed a new version of netbeans and upgraded from java 7 to 8. The new netbeans had a different version of glassfish, so I opened the properties of my project and pointed it to the right glassfish version and set the jdk to version 8.

#use return convertView;

Code:

public View getView(final int position, View convertView, ViewGroup parent) {

    //convertView = null;

    if (convertView == null) {

        LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        convertView = mInflater.inflate(R.layout.list_item, null);     

        TextView tv = (TextView) convertView.findViewById(R.id.name);
        Button rm_btn = (Button) convertView.findViewById(R.id.rm_btn);

        Model m = modelList.get(position);
        tv.setText(m.getName());

        // click listener for remove button  ??????????
        rm_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                modelList.remove(position);
                notifyDataSetChanged();
            }
        });
    }

    ///#use    return convertView;
    return convertView;
}

For Python 3, I did:

sudo apt install python3-dev postgresql postgresql-contrib python3-psycopg2 libpq-dev

and then I was able to do:

pip3 install psycopg2

Sometimes there is problem with java configuration. We need to provide it specifically.

<properties>
        <java.version>1.8</java.version>
</properties>

It solved my problem.

Try doing this:

                getSupportActionBar().setDisplayHomeAsUpEnabled(true);
                getSupportActionBar().setHomeButtonEnabled(true);
                actionBar = getSupportActionBar();
                actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);

Instead of this:

actionBar = getSupportActionBar();
                actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);

                getSupportActionBar().setDisplayHomeAsUpEnabled(true);
                getSupportActionBar().setHomeButtonEnabled(true);

android:layout_width="match_parent"
android:layout_height="wrap_content"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
android:paddingLeft="0dp">

This should be good enough.

I just changed minSdkVersion="7" in C:\MyApp\platforms\android\CordovaLib\AndroidManifest.xml and it worked.

Steps:

1. Path: C:\MyApp\platforms\android\CordovaLib\AndroidManifest.xml
2. Value: <uses-sdk android:minSdkVersion="7"/>

3. Ran command in new cmd prompt:

   C:\MyApp>phonegap build android --debug [phonegap] executing 'cordova build android --debug'... [phonegap] completed 'cordova build android --debug'

See this link it said that it will work when they are signed by the same key. The release key and the debug key are not the same.

So do it:

buildTypes {
        release {
            minifyEnabled true
            signingConfig signingConfigs.release//signing by the same key
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-android.txt'

        }
        debug {
            applicationIdSuffix ".debug"
            debuggable true
            signingConfig signingConfigs.release//signing by the same key
        }

    }

 signingConfigs {
        release {
            storeFile file("***\\key_.jks")
            storePassword "key_***"
            keyAlias "key_***"
            keyPassword "key_"***"
        }


}

Java:

yourButton.setAllCaps(false);

Kotlin:

yourButton.isAllCaps = false

XML:

android:textAllCaps="false"

Styles:

    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="buttonStyle">@style/yourButtonStyle</item>
    </style>

    <style name="yourButtonStyle" parent="Widget.AppCompat.Button">
        <item name="android:textAllCaps">false</item>
    </style>

In layout:

   <Button
      .
      .
      style="@style/yourButtonStyle"
      .
      .
   />

OK, I got the icons because I wrote in menu.xml android:showAsAction="ifRoom" instead of app:showAsAction="ifRoom" since i am using v7 library.

However the title is coming at center of extended toolbar. How to make it appear at the top?

An image of how to in Android Studio 1.5.1.

Within the "Android" project (see the drop-down in the topleft of my image), Right-click on the app...

As a oneliner guide:

minSdkVersion <= targetSdkVersion <= compileSdkVersion

Ideally:

minSdkVersion (lowest possible) <= targetSdkVersion == compileSdkVersion (latest SDK)

If you are on windows , you wouldn't need wheel anyway! You can directly install package by downloading the 32-bit package as win32 from this link [http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy] and then move that downloaded package to cmd's current directory and open cmd and write following codepip install numpy-1.13.1+mkl-cp36-cp36m-win32.whl then do it same for scipy

For 64-bit you need to install mingw-w64 as it is gcc and compiles numpy and scipy as precompiled status.

Currently it works fine with 32-bit.So I had opted for win32 package both for numpy+mkl and scipy in that link.

Hope This works! Give a try

My Problem has also been solved by changing in styles.xml

<!-- Base application theme. -->
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

Simply declare in styles.xml

  <style name="AppTheme.Fullscreen" parent="AppTheme">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:windowFullscreen">true</item>
  </style>

Then use in menifest.xml

    <activity
        android:name=".activities.Splash"
        android:theme="@style/AppTheme.Fullscreen">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

Chill Pill :)

Try this:

  <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:toolbar="http://schemas.android.com/apk/res-auto"
        android:id="@+id/tool_drawer"
        android:layout_width="match_parent"
        android:layout_height="?actionBarSize"
        toolbar:navigationIcon="@drawable/ic_navigation">

    </android.support.v7.widget.Toolbar>

Add this in your values/styles.xml

<style name="YourCustomTheme" parent="Theme.AppCompat.Light.NoActionBar">
</style>

<style name="AppBaseTheme" parent="YourCustomTheme">

</style>

<style name="AppTheme" parent="AppBaseTheme">

</style>

And add the following code in your values-v11/styles.xml and values-v14/styles.xml

<style name="AppBaseTheme" parent="YourCustomTheme">

</style>

Thats it. It will work.

I managed to load an application.properties file in external path while using -jar option.

The key was PropertiesLauncher.

To use PropertiesLauncher, pom.xml file must be changed like this:

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>  <!-- added -->
                <layout>ZIP</layout> <!-- to use PropertiesLaunchar -->
            </configuration>
        </plugin>
    </plugins>
</build>

For this, I referenced the following StackOverflow question: spring boot properties launcher unable to use . BTW, In Spring Boot Maven Plugin document(http://docs.spring.io/spring-boot/docs/1.1.7.RELEASE/maven-plugin/repackage-mojo.html), there is no mention that specifying ZIP triggers that PropertiesLauncher is used. (Perhaps in another document?)

After the jar file had been built, I could see that the PropertiesLauncher is used by inspecting Main-Class property in META-INF/MENIFEST.MF in the jar.

Now, I can run the jar as follows(in Windows):

java -Dloader.path=file:///C:/My/External/Dir,MyApp-0.0.1-SNAPSHOT.jar -jar MyApp-0.0.1-SNAPSHOT.jar

Note that the application jar file is included in loader.path.

Now an application.properties file in C:\My\External\Dir\config is loaded.

As a bonus, any file (for example, static html file) in that directory can also be accessed by the jar since it's in the loader path.

As for the non-jar (expanded) version mentioned in UPDATE 2, maybe there was a classpath order problem.

I just experienced the same behavior of tools:replace=... as described by the OP.

It turned out that the root cause for tools:replace being ignored by the manifest merger is a bug described here. It basically means that if you have a library in your project that contains a manifest with an <application ...> node containing a tools:ignore=... attribute, it can happen that the tools:replace=... attribute in the manifest of your main module will be ignored.

The tricky point here is that it can happen, but does not have to. In my case I had two libraries, library A with the tools:ignore=... attribute, library B with the attributes to be replaced in the respective manifests and the tools:replace=... attribute in the manifest of the main module. If the manifest of B was merged into the main manifest before the manifest of A everything worked as expected. In opposite merge order the error appeared.

The order in which these merges happen seems to be somewhat random. In my case changing the order in the dependencies section of build.gradle had no effect but changing the name of the flavor did it.

So, the only reliable workaround seems to be to unpack the problem causing library, remove the tools:ignore=... tag (which should be no problem as it is a hint for lint only) and pack the library again.

And vote for the bug to be fixed, of cause.

Specify a 'display-image' and 'full-size-image' as described here: http://www.informit.com/articles/article.aspx?p=1829415&seqNum=16

iOS8 requires these images

I had the same problem. This happened because of core library dependency. I was using javax.* . This is what i did to fix

In File->Project Structure->Dependencies I added this as as provided file, not a compile. Then re build the project.

This problem started after upgrade of android studio. But I think it happens when you try to edit you build files manually.

Just go to your fragment Activity and remove all method.....instead on on createview method.

your fragment has only on method oncreateview that's it.

//only this method implement other method delete

 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_main, container, false);
    return rootView;
}

and make sure your layout it is demo for u.

I received the same error while uploading a flutter app to playstore simply change the version code in pubspec.yaml worked for me. may be try changing the version code e.g from +1 to +2 and then rebuild the apk using

flutter build apk --split-per-abi 

and upload all the apk's to the playstore for your users. Next time when you want to push an update make sure to update the version code to +3 and so on.

Note: that the version code and version name are different you can see that in android/local.properties file. e.g version: 1.0.0+2

version is 1.0.0 and verison code is +2

I had this issue occurring with mailto: and tel: links inside an iframe (in Chrome, not a webview). Clicking the links would show the grey "page not found" page and inspecting the page showed it had a ERR_UNKNOWN_URL_SCHEME error.

Adding target="_blank", as suggested by this discussion of the issue fixed the problem for me.

File file=new File(getFilePath(imageUri.getValue()));
boolean b= file.delete();

not working in my case. The issue has been resolved by using below code-

ContentResolver contentResolver = getContentResolver ();
contentResolver.delete (uriDelete,null ,null );

I tried all the solution mentioned above

in Manifest.xml :

• add this code in top of your xml file within manifest tag:

  xmlns:tools="http://schemas.android.com/tools"

• Then added :

  tools:replace="android:icon,android:theme,android:label,android:name" to the application tag

but none of it worked. I needed to delete a xml file which was situated in

mipmap-anydpi-v26/ic_launcher_round.xml

I was testing the application in

Samsung Galaxy 8 with OS version 8.0.0

is it really a solution?

you need update.

This is my current solution (09/2015).

In Android Studio search.

Menu --> Help --> check for update

Upate and problem solved!!

Good luck

For me the issue like this is solved by changing the

minSdkVersion 14

In the build.gladdle file and use the one that is specified in the error message

but the issue was

Manifest merger failed : uses-sdk:minSdkVersion 14 cannot be smaller than version 15 declared in library

So I changed from 14 to 15 in the build.gladdle file and it works

give it a try.

Remove that statement from your manifest altogether, Eclipse will handle that for you on the fly.

Add followning code in Application.onCreate then use it normal

    Picasso picasso = new Picasso.Builder(context)
            .downloader(new OkHttp3Downloader(this,Integer.MAX_VALUE))
            .build();
    picasso.setIndicatorsEnabled(true);
    picasso.setLoggingEnabled(true);
    Picasso.setSingletonInstance(picasso);

If you cache images first then do something like this in ProductImageDownloader.doBackground

final Callback callback = new Callback() {
            @Override
            public void onSuccess() {
                downLatch.countDown();
                updateProgress();
            }

            @Override
            public void onError() {
                errorCount++;
                downLatch.countDown();
                updateProgress();
            }
        };
        Picasso.with(context).load(Constants.imagesUrl+productModel.getGalleryImage())
                .memoryPolicy(MemoryPolicy.NO_CACHE).fetch(callback);
        Picasso.with(context).load(Constants.imagesUrl+productModel.getLeftImage())
                .memoryPolicy(MemoryPolicy.NO_CACHE).fetch(callback);
        Picasso.with(context).load(Constants.imagesUrl+productModel.getRightImage())
                .memoryPolicy(MemoryPolicy.NO_CACHE).fetch(callback);

        try {
            downLatch.await();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        if(errorCount == 0){
            products.remove(productModel);
            productModel.isDownloaded = true;
            productsDatasource.updateElseInsert(productModel);
        }else {
            //error occurred while downloading images for this product
            //ignore error for now
            // FIXME: 9/27/2017 handle error
            products.remove(productModel);

        }
        errorCount = 0;
        downLatch = new CountDownLatch(3);

        if(!products.isEmpty() /*&& testCount++ < 30*/){
            startDownloading(products.get(0));
        }else {
            //all products with images are downloaded
            publishProgress(100);
        }

and load your images like normal or with disk caching

    Picasso.with(this).load(Constants.imagesUrl+batterProduct.getGalleryImage())
        .networkPolicy(NetworkPolicy.OFFLINE)
        .placeholder(R.drawable.GalleryDefaultImage)
        .error(R.drawable.GalleryDefaultImage)
        .into(viewGallery);

Note:

Red color indicates that image is fetched from network.

Green color indicates that image is fetched from cache memory.

Blue color indicates that image is fetched from disk memory.

Before releasing the app delete or set it false picasso.setLoggingEnabled(true);, picasso.setIndicatorsEnabled(true); if not required. Thankx

The Android implementation of mipmaps in 4.3 is exactly the technique from 1983 explained in the Wikipedia article :)

Each bitmap image of the mipmap set is a downsized duplicate of the main texture, but at a certain reduced level of detail. Although the main texture would still be used when the view is sufficient to render it in full detail, the renderer will switch to a suitable mipmap image (...) when the texture is viewed from a distance or at a small size.

Although this is described as a technique for 3D graphics (as it mentions "viewing from a distance"), it applies just as well to 2D (translated as "drawn is a smaller space", i.e. "downscaled").

For a concrete Android example, imagine you have a View with a certain background drawable (in particular, a BitmapDrawable). You now use an animation to scale it to 0.15 of its original size. Normally, this would require downscaling the background bitmap for each frame. This "extreme" downscaling, however, may produce visual artifacts.

You can, however, provide a mipmap, which means that the image is already pre-rendered for a few specific scales (let's say 1.0, 0.5, and 0.25). Whenever the animation "crosses" the 0.5 threshold, instead of continuing to downscale the original, 1.0-sized image, it will switch to the 0.5 image and downscale it, which should provide a better result. And so forth as the animation continues.

This is a bit theoretical, since it's actually done by the renderer. According to the source of the Bitmap class, it's just a hint, and the renderer may or may not honor it.

/**
 * Set a hint for the renderer responsible for drawing this bitmap
 * indicating that it should attempt to use mipmaps when this bitmap
 * is drawn scaled down.
 *
 * If you know that you are going to draw this bitmap at less than
 * 50% of its original size, you may be able to obtain a higher
 * quality by turning this property on.
 * 
 * Note that if the renderer respects this hint it might have to
 * allocate extra memory to hold the mipmap levels for this bitmap.
 *
 * This property is only a suggestion that can be ignored by the
 * renderer. It is not guaranteed to have any effect.
 *
 * @param hasMipMap indicates whether the renderer should attempt
 *                  to use mipmaps
 *
 * @see #hasMipMap()
 */
public final void setHasMipMap(boolean hasMipMap) {
    nativeSetHasMipMap(mNativeBitmap, hasMipMap);
}

I'm not quite sure why this would be especially suitable for application icons, though. Although Android on tablets, as well as some launchers (e.g. GEL), request an icon "one density higher" to show it bigger, this is supposed to be done using the regular mechanism (i.e. drawable-xxxhdpi, &c).

You need to add icon.png through visual.

Resouces... / Dravable/ Add ///

It's not enough to have just compile project("xy") dependency. You need to configure root project to include all modules (or to call them subprojects but that might not be correct word here).

Create a settings.gradle file in the root of your project and add this:

include ':progressfragment'

to that file. Then sync Gradle and it should work.

Also one interesting side note: If you add ':unexistingProject' in settings.gradle (project that you haven't created yet), Gradle will create folder for this project after sync (at least in Android studio this is how it behaves). So, to avoid errors with settings.gradle when you create project from existing files, first add that line to file, sync and then put existing code in created folder. Unwanted behavior arising from this might be that if you delete the project folder and then sync folder will come back empty because Gradle sync recreated it since it is still listed in settings.gradle.

In my case the issue was the WIFI Configuration that was static had a conflict with another device using the same IP Address.

Okay, redis is pretty user friendly but there are some gotchas.

Here are just some easy commands for working with redis on Ubuntu:

install:

sudo apt-get install redis-server

start with conf:

sudo redis-server <path to conf>
sudo redis-server config/redis.conf

stop with conf:

redis-ctl shutdown

(not sure how this shuts down the pid specified in the conf. Redis must save the path to the pid somewhere on boot)

log:

tail -f /var/log/redis/redis-server.log

Also, various example confs floating around online and on this site were beyond useless. The best, sure fire way to get a compatible conf is to copy-paste the one your installation is already using. You should be able to find it here:

/etc/redis/redis.conf

Then paste it at <path to conf>, tweak as needed and you're good to go.

Override onDestroy of the Activity and Dismiss your Dialog & make it null

protected void onDestroy ()
    {
        if(mProgressDialog != null)
            if(mProgressDialog.isShowing())
                mProgressDialog.dismiss();
        mProgressDialog= null;
    }

I also facing this issue but i follow the following steps:-- 1) I add module(Library) to a particular folder name ThirdPartyLib

To resolve this issue i go settings.gradle than just add follwing:-

project(':').projectDir = new File('ThirdPartyLib/')

:- is module name...

Alright so I guess the thing to do is add my answer here to this long list versus creating a duplicate question...

If you are getting this in 2019, using .NET Core 3.0 (Preview at this time), the solution is to ensure all projects are targeting the same .NET Core version (in my case 3.0). I think I had one project in the solution targeting 2.1 and the rest were 2.2 so I probably could have stuck with 2.2...

I don't even have Newtonsoft.Json installed in any of the projects, and naturally adding it to them did not fix the issue.

If you have .NET Standard class libraries or w/e in your solution, they don't need to be on the same version, though they should probably be the latest you can go. For example, my .NET Standard class libraries are on 2.2 as there is not a .NET Standard 3.0 yet.

As many already noticed, the problem manifests itself only if the extra string contains whitespaces.

The root cause is that OP's host OS/shell (i.e. Windows/cmd.exe) mangles the entered command - the " characters get lost, --es sms_body "test from adb" becomes --es sms_body test from adb. Which results in sms_body string extra getting assigned the value of test and the rest of the string becoming <URI>|<PACKAGE>|<COMPONENT> specifier.

To avoid all that you could use:

adb shell "am broadcast -a com.whereismywifeserver.intent.TEST --es sms_body 'test from adb' -n com.whereismywifeserver/.IntentReceiver"

or just start the interactive adb shell session first and run the am broadcast command from inside of it.

I had the same error. Creating a new AVD with the appropriate API level solved my problem.

I've been struggling with it for a day or so too, tried every solution. What helped me was to check that capital letters in app.config. I had PublicKeyToken instead of publicKeyToken, after changing it suddenly worked.

I had the same error and some answers mislead me on a newbie issue. I had the wrong package in my custom view descriptor like below. I hope it helps somebody.

<com.my.app.wrong.package.MyActivity
    android:id="@+id/myActivity"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="16dp"
    android:layout_marginRight="16dp"
    android:paddingTop="16dp"
    android:paddingBottom="8dp"
    android:gravity="left" />

Android version and code version number change on Android Studio >= 3.6:

Two ways to achieve this:

1. Direct on the Android project by Open Flutter project and modify the file

   local.properties

change the following values. Example:

flutter.buildMode=release
flutter.versionName=3.0.0
flutter.sdk=C\:\\src\\flutter
sdk.dir=C\:\\Users\\vgonza\\AppData\\Local\\Android\\sdk
flutter.versionCode=30

2. Open pubspec.yaml

Change the

version: 2.0.0+8

Meaning: The version name is 2.0.0 The version code is 8

See example by Suragch in:

How to set build and version number of Flutter app

taking @rijul's answer forward, it doesn't work in marshmallow and above versions:

       //for pre-marshmallow versions
       String path = System.getenv("SECONDARY_STORAGE");

       // For Marshmallow, use getExternalCacheDirs() instead of System.getenv("SECONDARY_STORAGE")
       if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
           File[] externalCacheDirs = mContext.getExternalCacheDirs();
           for (File file : externalCacheDirs) {
               if (Environment.isExternalStorageRemovable(file)) {
                   // Path is in format /storage.../Android....
                   // Get everything before /Android
                   path = file.getPath().split("/Android")[0];
                   break;
               }
           }
       }


        // Android avd emulator doesn't support this variable name so using other one
        if ((null == path) || (path.length() == 0))
            path = Environment.getExternalStorageDirectory().getAbsolutePath();

for me a solution, after trying all solutions from here, was to change

    <activity
        android:name="com.github.cythara.MainActivity"
        android:label="Main">
    </activity>

to include a theme:

    <activity
        android:name="com.github.cythara.MainActivity"
        android:theme="@style/Theme.AppCompat.NoActionBar"
        android:label="Main">
    </activity>

R.id.button is not part of R.layout.activity_main. How should the activity find it in the content view?

The layout that contains the button is displayed by the Fragment, so you have to get the Button there, in the Fragment.

Thanks jbaliuka for the suggestion. I opened the registry editor (by typing regedit in cmd) and going to HKEY_CLASSES_ROOT > jarfile > shell > open > command, then opening (Default) and changing the value from

"C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*

to

"C:\Program Files\Java\jre7\bin\java.exe" -jar "%1" %*

(I just removed the w in javaw.exe.) After that you have to right click a jar -> open with -> choose default program -> navigate to your java folder and open \jre7\bin\java.exe (or any other java.exe file in you java folder). If it doesn't work, try switching to javaw.exe, open a jar file with it, then switch back.

I don't know anything about editing the registry except that it's dangerous, so you might wanna back it up before doing this (in the top bar, File>Export).

There are two solutions I really like. The first depends on the Play Store and the other depends on Git.

Using the Play Store, you can increment the version code by looking at the highest available uploaded version code. The benefit of this solution is that an APK upload will never fail since your version code is always one higher than whatever is on the Play Store. The downside is that distributing your APK outside of the Play Store becomes more difficult. You can set this up using Gradle Play Publisher by following the quickstart guide and telling the plugin to resolve version codes automatically:

plugins {
    id 'com.android.application'
    id 'com.github.triplet.play' version 'x.x.x'
}

android {
    ...
}

play {
    serviceAccountCredentials = file("your-credentials.json")
    resolutionStrategy = "auto"
}

Using Git, you can increment the version code based on how many commits and tags your repository has. The benefit here is that your output is reproducible and doesn't depend on anything outside your repo. The downside is that you have to make a new commit or tag to bump your version code. You can set this up by adding the Version Master Gradle plugin:

plugins {
    id 'com.android.application'
    id 'com.supercilex.gradle.versions' version 'x.x.x'
}

android {
    ...
}

If you'd like to set this globally for all users of a machine, you can create the following directory and file structures:

mkdir %windir%\Sun\Java\Deployment

Create a file deployment.config with the content:

deployment.system.config=file:///c:/windows/Sun/Java/Deployment/deployment.properties
deployment.system.config.mandatory=TRUE

Create a file deployment.properties

deployment.user.security.exception.sites=C\:/WINDOWS/Sun/Java/Deployment/exception.sites

Create a file exception.sites

http://example1.com
http://example2.com/path/to/specific/directory/

Reference https://blogs.oracle.com/java-platform-group/entry/upcoming_exception_site_list_in

In Android 8.1 it is must to turned Location on to get SSID, if not you can get connection state but not SSID

WifiManager wifiManager = (WifiManager) context.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = null;
if (wifiManager != null) 
wifiInfo = wifiManager.getConnectionInfo();
 String ssid = null;
if (wifiInfo != null) 
ssid = wifiInfo.getSSID(); /*you will get SSID <unknown ssid> if location turned off*/

Its very easy just do the following:

add the following line in your manifest.json

"content_security_policy": "script-src 'self' https://ajax.googleapis.com; object-src 'self'",

Now you are free to load jQuery directly from url

  <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>

Imp. TIP :

Whenever you have heavyweight initialization that should be done once for many RDD elements rather than once per RDD element, and if this initialization, such as creation of objects from a third-party library, cannot be serialized (so that Spark can transmit it across the cluster to the worker nodes), use mapPartitions() instead of map(). mapPartitions() provides for the initialization to be done once per worker task/thread/partition instead of once per RDD data element for example : see below.

val newRd = myRdd.mapPartitions(partition => {
  val connection = new DbConnection /*creates a db connection per partition*/

  val newPartition = partition.map(record => {
    readMatchingFromDB(record, connection)
  }).toList // consumes the iterator, thus calls readMatchingFromDB 

  connection.close() // close dbconnection here
  newPartition.iterator // create a new iterator
})

Q2. does flatMap behave like map or like mapPartitions?

Yes. please see example 2 of flatmap.. its self explanatory.

Q1. What's the difference between an RDD's map and mapPartitions

map works the function being utilized at a per element level while mapPartitions exercises the function at the partition level.

Example Scenario : if we have 100K elements in a particular RDD partition then we will fire off the function being used by the mapping transformation 100K times when we use map.

Conversely, if we use mapPartitions then we will only call the particular function one time, but we will pass in all 100K records and get back all responses in one function call.

There will be performance gain since map works on a particular function so many times, especially if the function is doing something expensive each time that it wouldn't need to do if we passed in all the elements at once(in case of mappartitions).

map

Applies a transformation function on each item of the RDD and returns the result as a new RDD.

Listing Variants

def map[U: ClassTag](f: T => U): RDD[U]

Example :

val a = sc.parallelize(List("dog", "salmon", "salmon", "rat", "elephant"), 3)
 val b = a.map(_.length)
 val c = a.zip(b)
 c.collect
 res0: Array[(String, Int)] = Array((dog,3), (salmon,6), (salmon,6), (rat,3), (elephant,8)) 

mapPartitions

This is a specialized map that is called only once for each partition. The entire content of the respective partitions is available as a sequential stream of values via the input argument (Iterarator[T]). The custom function must return yet another Iterator[U]. The combined result iterators are automatically converted into a new RDD. Please note, that the tuples (3,4) and (6,7) are missing from the following result due to the partitioning we chose.

preservesPartitioning indicates whether the input function preserves the partitioner, which should be false unless this is a pair RDD and the input function doesn't modify the keys.

Listing Variants

def mapPartitions[U: ClassTag](f: Iterator[T] => Iterator[U], preservesPartitioning: Boolean = false): RDD[U]

Example 1

val a = sc.parallelize(1 to 9, 3)
 def myfunc[T](iter: Iterator[T]) : Iterator[(T, T)] = {
   var res = List[(T, T)]()
   var pre = iter.next
   while (iter.hasNext)
   {
     val cur = iter.next;
     res .::= (pre, cur)
     pre = cur;
   }
   res.iterator
 }
 a.mapPartitions(myfunc).collect
 res0: Array[(Int, Int)] = Array((2,3), (1,2), (5,6), (4,5), (8,9), (7,8)) 

Example 2

val x = sc.parallelize(List(1, 2, 3, 4, 5, 6, 7, 8, 9,10), 3)
 def myfunc(iter: Iterator[Int]) : Iterator[Int] = {
   var res = List[Int]()
   while (iter.hasNext) {
     val cur = iter.next;
     res = res ::: List.fill(scala.util.Random.nextInt(10))(cur)
   }
   res.iterator
 }
 x.mapPartitions(myfunc).collect
 // some of the number are not outputted at all. This is because the random number generated for it is zero.
 res8: Array[Int] = Array(1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 5, 7, 7, 7, 9, 9, 10) 

The above program can also be written using flatMap as follows.

Example 2 using flatmap

val x  = sc.parallelize(1 to 10, 3)
 x.flatMap(List.fill(scala.util.Random.nextInt(10))(_)).collect

 res1: Array[Int] = Array(1, 2, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 4, 5, 5, 6, 6, 6, 6, 6, 6, 6, 6, 7, 7, 7, 8, 8, 8, 8, 8, 8, 8, 8, 9, 9, 9, 9, 9, 10, 10, 10, 10, 10, 10, 10, 10) 

Conclusion :

mapPartitions transformation is faster than map since it calls your function once/partition, not once/element..

Further reading : foreach Vs foreachPartitions When to use What?

export default function(){} can be used when the function doesn't have a name. There can only be one default export in a file. The alternative is a named export.

This page describes export default in detail as well as other details about modules that I found very helpful.

I had exactly the same error, but I installed postgreSQL through brew and re-run the original command and it worked perfectly :

brew install postgresql

With some help from another person, we figured out it was an issue of ordering the source files within the HTML file. I learned that browsers accept the first usable format, and their seems to be an issue with the .m4v file, so I started with the .mp4, then .webm. Here's the order that works in Safari (even on my iPhone 5), Firefox, and Chrome:

<video width="100%" height="400" poster="assets/img/myVideo.jpg" controls="controls" preload="none">
      <!-- MP4 for Safari, IE9, iPhone, iPad, Android, and Windows Phone 7 -->
      <source type="video/mp4" src="assets/vid/PhysicsEtoys.mp4" />
      <!-- WebM/VP8 for Firefox4, Opera, and Chrome -->
      <source type="video/webm" src="assets/vid/PhysicsEtoys.webm" />
       <!-- M4V for Apple -->
      <source type="video/mp4" src="assets/vid/PhysicsEtoys.m4v" />
      <!-- Ogg/Vorbis for older Firefox and Opera versions -->
      <source type="video/ogg" src="assets/vid/PhysicsEtoys.ogv" />
      <!-- Subtitles -->
      <track kind="subtitles" src="assets/vid/subtitles.srt" srclang="en" />
      <track kind="subtitles" src="assets/vid/subtitles.vtt" srclang="en" />
      <!-- Flash fallback for non-HTML5 browsers without JavaScript -->
      <object width="100%" height="400" type="application/x-shockwave-flash" data="flashmediaelement.swf">
          <param name="movie" value="flashmediaelement.swf" />
          <param name="flashvars" value="controls=true&file=assets/vid/PhysicsEtoys.mp4" />
          <!-- Image as a last resort -->
          <img src="assets/img/myVideo.jpg" width="320" height="240" title="No video playback capabilities" />
      </object>
  </video>

Now, I'll have to re-check the encoding on the m4v file (perhaps an issue of Baseline vs Main, High, etc.).

Check if you are building hidden version. That’s intended behavior for hidden app.

If you want to build regular version, you need to change Build Variant in Android Studio Build > Select Build Variant, change it to regular.

May be your dependencies not build correctly. Check compilation issue in project.

Clean and rebuild project.

For maven project: mvn clean install

For gradle projects: gradle clean build or gradlew clean build

For me it was that I forgot to install the 32bit dependencies:

sudo apt-get install -y lib32gcc1 libc6-i386 lib32z1 lib32stdc++6
sudo apt-get install -y lib32ncurses5 lib32gomp1 lib32z1-dev lib32bz2-dev

You have configured the auth.php and used members table for authentication but there is no user_email field in the members table so, Laravel says

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'user_email' in 'where clause' (SQL: select * from members where user_email = ? limit 1) (Bindings: array ( 0 => '[email protected]', ))

Because, it tries to match the user_email in the members table and it's not there. According to your auth configuration, laravel is using members table for authentication not users table.

In my case I had to include several additional exclusions. It appears it doesn't like Regular expressions which would've made this a nice one-liner.

}

in build.gradle file.

it works

You will need to define the repository outside of buildscript. The buildscript configuration block only sets up the repositories and dependencies for the classpath of your build script but not your application.

Your error is in UpdaterServiceManager in onCreate and showNotification method.

You are trying to show notification from Service using Activity Context. Whereas Every Service has its own Context, just use the that. You don't need to pass a Service an Activity's Context.I don't see why you need a specific Activity's Context to show Notification.

Put your createNotification method in UpdateServiceManager.class. And remove CreateNotificationActivity not from Service.

You cannot display an application window/dialog through a Context that is not an Activity. Try passing a valid activity reference

You can get the context using getActivity().getApplicationContext();

start the sql server agent, that should fix your problem

I'm using vs2012 and i think the update KB2781514 changed some setting. All my System.Web.Http in my MVC4 project changed to false and i keeping received this message. I had changed the All file in this project in publish property but its not working. Finally I have to change Copy Local = true one by one and solved this problem.

Your Maven is reading Java version as 1.6.0_65, Where as the pom.xml says the version is 1.7.

Try installing the required verison.

If already installed check your $JAVA_HOME environment variable, it should contain the path of Java JDK 7. If you dont find it, fix your environment variable.

also remove the lines

 <fork>true</fork>
     <executable>${JAVA_1_7_HOME}/bin/javac</executable>

from the pom.xml

I was getting the same error; I had previously installed the google-play-services_lib for Google Maps (and it was working fine) but then when I later tried adding the meta-data entry to my Manifest I was getting the error. I tried all the above suggestions but nothing would link them properly; I finally removed the link from my project (project-properties-Android, remove google-play-services_lib library), then removed from Eclipse workspace, deleted the files on the disk, and finally used the SDK manager to reinstall from scratch.

That seemed to finally do the trick; now Eclipse has decided to allow me to leave the meta-data entry with no errors.

I had the same problem, add this 2 line in your build.gradle the problem will be resolved probably. ;)

dependencies {  
  implementation 'com.google.android.gms:play-services:12.0.1'  
  implementation 'com.google.android.gms:play-services-vision:10.0.0'    
}

Add android:exported="true" in your 'com.example.lib.MainActivity' activity tag.

From the android:exported documentation,

android:exported Whether or not the activity can be launched by components of other applications — "true" if it can be, and "false" if not. If "false", the activity can be launched only by components of the same application or applications with the same user ID.

From your logcat output, clearly a mismatch in uid is causing the issue. So adding the android:exported="true" should do the trick.

The terms "background page", "popup", "content script" are still confusing you; I strongly suggest a more in-depth look at the Google Chrome Extensions Documentation.

Regarding your question if content scripts or background pages are the way to go:

Content scripts: Definitely
Content scripts are the only component of an extension that has access to the web-page's DOM.

Background page / Popup: Maybe (probably max. 1 of the two)
You may need to have the content script pass the DOM content to either a background page or the popup for further processing.

Let me repeat that I strongly recommend a more careful study of the available documentation!
That said, here is a sample extension that retrieves the DOM content on StackOverflow pages and sends it to the background page, which in turn prints it in the console:

background.js:

// Regex-pattern to check URLs against. 
// It matches URLs like: http[s]://[...]stackoverflow.com[...]
var urlRegex = /^https?:\/\/(?:[^./?#]+\.)?stackoverflow\.com/;

// A function to use as callback
function doStuffWithDom(domContent) {
    console.log('I received the following DOM content:\n' + domContent);
}

// When the browser-action button is clicked...
chrome.browserAction.onClicked.addListener(function (tab) {
    // ...check the URL of the active tab against our pattern and...
    if (urlRegex.test(tab.url)) {
        // ...if it matches, send a message specifying a callback too
        chrome.tabs.sendMessage(tab.id, {text: 'report_back'}, doStuffWithDom);
    }
});

content.js:

// Listen for messages
chrome.runtime.onMessage.addListener(function (msg, sender, sendResponse) {
    // If the received message has the expected format...
    if (msg.text === 'report_back') {
        // Call the specified callback, passing
        // the web-page's DOM content as argument
        sendResponse(document.all[0].outerHTML);
    }
});

manifest.json:

{
  "manifest_version": 2,
  "name": "Test Extension",
  "version": "0.0",
  ...

  "background": {
    "persistent": false,
    "scripts": ["background.js"]
  },
  "content_scripts": [{
    "matches": ["*://*.stackoverflow.com/*"],
    "js": ["content.js"]
  }],
  "browser_action": {
    "default_title": "Test Extension"
  },

  "permissions": ["activeTab"]
}

To hide the ActionBar add this code into java file.

    ActionBar actionBar = getSupportActionBar();
    actionBar.hide();

Believe me or not... I tried out almost each answer I had found here on stackoverflow. Nothing would help, until I just restarted the machine. My Android Studio works on Ubuntu 16.04 LTS.

To resolve the Could not load file or assembly 'System.Web.Http' error use NuGet to install the Web API 2.1 WebHost.

In solution explorer in the references right click and select manage nuget packages. (if not there install nuget)

In the manage NuGet Packages window on the left side click online then in top right search for Web Host and install Microsoft ASP.NET Web API 2.1 Web Host. (Once installed the install button will change to a green check)

After that the project will reload and when it's build again the error will be resolved and the project will debug and run. The error will be gone and you may be 'The resource cannot be found. Just append the url ( ex from localhost:52088/ to localhost:52088api/products )

Your question was good and helped me.

Hope this answer helps!

Changing the minSdkVersion in the manifest is not necessary. If you change it in the gradle build file, as seen below, you accomplish what you need to do.

defaultConfig {
   applicationId "com.demo.myanswer"
   minSdkVersion 14
   targetSdkVersion 23
   versionCode 1
   versionName "1.0"
}

You need to include "Main class" attribute in Manisfest.mf file in Jar

For example: Main-Class: MyClassName

Second thing, To add Manifest file in Your jar, You can manually create file in your workspace folder, and refresh in Eclipse Project explorer.

While exporting, Eclipse will create a Jar which will include your manifest.

Cheers !!

To change your application to a different built-in theme, just add this line under application tag in your app's manifest.xml file.

Example:

<application 
    android:theme="@android:style/Theme.Holo"/>

<application 
    android:theme="@android:style/Theme.Holo.Light"/>

<application 
    android:theme="@android:style/Theme.Black"/>

<application 
    android:theme="@android:style/Theme.DeviceDefault"/>

If you set style to DeviceDefault it will require min SDK version 14, but if you won't add a style, it will set to the device default anyway.

<uses-sdk
    android:minSdkVersion="14"/>

This may be an old post, but if anyone is still facing this issue after trying all the above mentioned steps, ensure whether the default path of PowerShell module is specified under the "PSModulePath" environment variable.

The default path should be "%SystemRoot%\system32\WindowsPowerShell\v1.0\Modules\"

I experienced this issue when I tried to update a Hot Towel Project from the project template and when I created an empty project and installed HotTowel via nuget in VS 2012 as of 10/23/2013.

To fix, I updated via Nuget the Web Api Web Host and Web API packages to 5.0, the current version in NuGet at the moment (10/23/2013).

I then added the binding directs:

<dependentAssembly>
  <assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" culture="neutral" />
  <bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
</dependentAssembly>
<dependentAssembly>
  <assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" culture="neutral" />
  <bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
</dependentAssembly>

Use the following functions to show/hide the keyboard:

/**
 * Hides the soft keyboard
 */
public void hideSoftKeyboard() {
    if(getCurrentFocus()!=null) {
        InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
        inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
    }
}

/**
 * Shows the soft keyboard
 */
public void showSoftKeyboard(View view) {
    InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
    view.requestFocus();
    inputMethodManager.showSoftInput(view, 0);
}

UPDATE:

Since the version 22.1.0, the class ActionBarActivity is deprecated, so instead use AppCompatActivity. For more details see here

Using ActionBarActivity:

In Eclipse:

1 - Make sure library project(appcompat_v7) is open & is proper referenced (added as library) in your application project.

2 - Delete android-support-v4.jar from your project's libs folder(if jar is present).

3 - Appcompat_v7 must have android-support-v4.jar & android-support-v7-appcompat.jar inside it's libs folder. (If jars are not present copy them from /sdk/extras/android/support/v7/appcompat/libs folder of your installed android sdk location)

4- Check whether ActionBarActivity is properly imported.

import android.support.v7.app.ActionBarActivity;

In Android Studio

Just add compile dependencies to app's build.gradle

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.1.1'
}

I usually do the following for my rails 4 projects:

In application.js

function onInit(callback){
    $(document).ready(callback);
    $(document).on('page:load', callback);
}

Then in the rest of the .js files, instead of using $(function (){}) I call onInit(function(){})

You can use .filter() with boolean operators ie &&:

     var find = my_array.filter(function(result) {
       return result.param1 === "srting1" && result.param2 === 'string2';
     });
     
     return find[0];

This works for me,

sudo chmod -R 777 /var/log/nginx

I was facing a problem while calling cross origin resource using ajax from chrome.

I have used node js and local http server to deploy my node js app.

I was getting error response, when I access cross origin resource

I found one solution on that ,

1) I have added below code to my app.js file

res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "X-Requested-With");

2) In my html page called cross origin resource using $.getJSON();

$.getJSON("http://localhost:3000/users", function (data) {
    alert("*******Success*********");
    var response=JSON.stringify(data);
    alert("success="+response);
    document.getElementById("employeeDetails").value=response;
});

From version 4.x, only Android SDK 24+ is supported by default, and androidx is required.

Add the following to your build.gradle file:

repositories {
    jcenter()
}

dependencies {
    implementation 'com.journeyapps:zxing-android-embedded:4.1.0'
    implementation 'androidx.appcompat:appcompat:1.0.2'
}

android {
    buildToolsVersion '28.0.3' // Older versions may give compile errors
}

Older SDK versions

For Android SDK versions < 24, you can downgrade zxing:core to 3.3.0 or earlier for Android 14+ support:

repositories {
    jcenter()
}

dependencies {
    implementation('com.journeyapps:zxing-android-embedded:4.1.0') { transitive = false }
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'com.google.zxing:core:3.3.0'
}

android {
    buildToolsVersion '28.0.3'
}

You'll also need this in your Android manifest:

<uses-sdk tools:overrideLibrary="com.google.zxing.client.android" />

Source : https://github.com/journeyapps/zxing-android-embedded

Run a jar file and specify a class path like this:

java -cp <jar_name.jar:libs/*> com.test.App

jar_name.jar is the full name of the JAR you want to execute

libs/* is a path to your dependency JARs

com.test.App is the fully qualified name of the class from the JAR that has the main(String[]) method

The jar and dependent jar should have execute permissions.

You can change this one parent attribute ="android:style/Theme.Holo.Light.DarkActionBar"

For Windows:

If pip is not available when Python is downloaded: run the command

python get-pip.py

Use

apply plugin: 'com.android.library'

to convert an app module to a library module. More info here: https://developer.android.com/studio/projects/android-library.html

I had the same issue i have created own API to check whether google play service is installed or not , it works fine for me. Just pass package information of google play service it will give you the value

below is the code:

public static boolean isGooglePlayServicesInstalled()
{
try
{
ApplicationInfo info = NativeActivity.CURRENT.getPackageManager().getApplicationInfo("com.google.android.gms", 0 );
 LOG.d(LOG_IDENTIFIER, "info : "+ info);
return true;
}
catch(PackageManager.NameNotFoundException e)
{
e.printStackTrace();
LOG.e(LOG_IDENTIFIER, "NameNotFoundException : "+ e.getMessage());
}
return false;
}

para resolver o meu problema, eu apenas adicionei na minha MainActivity ("Theme = To solve my problem, I just added it in my MainActivity ("Theme =" @ style / MyTheme "") where MyTheme is the name of my theme

[Activity(Label = "Name Label", MainLauncher = true, Icon = "@drawable/icon", LaunchMode = LaunchMode.SingleTop, Theme = "@style/MyTheme")]

If you are also using Dagger or Butterknife you should to add guava as a dependency to your build.gradle main file like classpath :

com.google.guava:guava:20.0

In other hand, if you are having problems with larger heap for the Gradle daemon you can increase adding to your radle file:

 dexOptions {
        javaMaxHeapSize "4g"
    } 

For IntelliJ IDEA or Android Studio:

Add this to app.gradle build file

dependencies {
    compile "com.android.support:appcompat-v7:21.0.+"
} 

Replace -v:xx.0+, with your build target, if you have 19 platform then it must be like:

dependencies {
    compile "com.android.support:appcompat-v7:19.0.+"
}

Add this permission in Manifest,
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

File folder = new File(Environment.getExternalStorageDirectory() + 
                             File.separator + "TollCulator");
boolean success = true;
if (!folder.exists()) {
    success = folder.mkdirs();
}
if (success) {
    // Do something on success
} else {
    // Do something else on failure 
}

when u run the application go too DDMS->File Explorer->mnt folder->sdcard folder->toll-creation folder

As per http://content-security-policy.com/ The best place to start:

    default-src 'none'; 
    script-src 'self'; 
    connect-src 'self'; 
    img-src 'self'; 
    style-src 'self';
    font-src 'self';

Never inline styles or scripts as it undermines the purpose of CSP. You can use a stylesheet to set a style property and then use a function in a .js file to change the style property (if need be).

Take a look at this question.

TL;DR: clean, then build.

./gradlew clean packageDebug 

I'm using this tutorial and it works nicely for my application.

In my activity I put this code:

GPSTracker tracker = new GPSTracker(this);
    if (!tracker.canGetLocation()) {
        tracker.showSettingsAlert();
    } else {
        latitude = tracker.getLatitude();
        longitude = tracker.getLongitude();
    }

also check if your emulator runs with Google API

Maybe you have some duplicated Activities

Like this:

<activity android:name=".register.RegisterStepsActivity" />

....

<activity android:name=".register.RegisterStepsActivity" />

just comment one of them

1) place setContentView(R.layout.avtivity_next); to the next-activity's onCreate() method just like this (main) activity's onCreate()

2) if you have not defined the next-activity in your-apps manifest file then do this also, like:

<application
        android:allowBackup="true"
        android:icon="@drawable/app_icon"
        android:label="@string/app_name" >
        <activity
            android:name=".MainActivity"
            android:label="Main Activity" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".NextActivity"
            android:label="Next Activity" >
        </activity>
    </application>

You must have to perform the 2nd step every time you create a new activity, otherwise your app will crash

String dir="/Attendancesystem";

 public void displaypdf() {

        File file = null;
            file = new File(Environment.getExternalStorageDirectory()+dir+ "/sample.pdf");
        Toast.makeText(getApplicationContext(), file.toString() , Toast.LENGTH_LONG).show();
        if(file.exists()) {
            Intent target = new Intent(Intent.ACTION_VIEW);
            target.setDataAndType(Uri.fromFile(file), "application/pdf");
            target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

            Intent intent = Intent.createChooser(target, "Open File");
            try {
                startActivity(intent);
            } catch (ActivityNotFoundException e) {
                // Instruct the user to install a PDF reader here, or something
            }
        }
        else
            Toast.makeText(getApplicationContext(), "File path is incorrect." , Toast.LENGTH_LONG).show();
    }

As doc says also keep in mind the correct value combination:

The setting must be one of the values listed in the following table, or a combination of one "state..." value plus one "adjust..." value. Setting multiple values in either group — multiple "state..." values, for example — has undefined results. Individual values are separated by a vertical bar (|). For example:

<activity android:windowSoftInputMode="stateVisible|adjustResize" . . . >

Write your permission before the application tag as given below.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.someapp.sample">

    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme">

the issue happened with me, I resolved by removing the scope tag only and built successfully.

there is an official YouTube Android Player API wich you can use. This is a bit more complicated but it is working better than other solutions using webclients.

First you must register your app in Googles API Console. This is completely free until your app gets over 25k request a month (or something like that). There are complete anf great tutorials under the link. I hope you can understand them. If not, ask! :)

Simply resolved by doing the following:

• (sudo) gem install cocoapods

• pod install

• clean and build

it seems the problem was caused by one of our team members having a more recent cocoapods gem installation.

In runtime problems like these firstly open logcat if you are using android studio, try to analyse trace tree, go to the beginning from where exception started to rise, since that is usually the source of the problem. Now check for two things:

1. Check in device file explorer(on the bottom right) there exist a database created by you. mostly you find it in DATA -> DATA -> com.example.hpc.demo(your pakage name) -> DATABASE -> demo.db

2. Check that in your helper class you have added required '/' for example like below
   DB_location = "data/data/" + mcontext.getPackageName() + "/database/";

Put these two line in your AndroidMainfest

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 

It is possible and is deceptively easy:

1. "Publish" the application (to, say, some folder on drive C), either from menu Build or from the project's properties ? Publish. This will create an installer for a ClickOnce application.
2. But instead of using the produced installer, find the produced files (the EXE file and the .config, .manifest, and .application files, along with any DLL files, etc.) - they are all in the same folder and typically in the bin\Debug folder below the project file (.csproj).
3. Zip that folder (leave out any *.vhost.* files and the app.publish folder (they are not needed), and the .pdb files unless you foresee debugging directly on your user's system (for example, by remote control)), and provide it to the users.

An added advantage is that, as a ClickOnce application, it does not require administrative privileges to run (if your application follows the normal guidelines for which folders to use for application data, etc.).

As for .NET, you can check for the minimum required version of .NET being installed (or at all) in the application (most users will already have it installed) and present a dialog with a link to the download page on the Microsoft website (or point to one of your pages that could redirect to the Microsoft page - this makes it more robust if the Microsoft URL change). As it is a small utility, you could target .NET 2.0 to reduce the probability of a user to have to install .NET.

It works. We use this method during development and test to avoid having to constantly uninstall and install the application and still being quite close to how the final application will run.

Here is my solution for mac users I think it work for window also:

First go to your Android Studio toolbar

Build > Make Project (while you guys are online let it to download the files) and then

Build > Compile Module "your app name is shown here" (still online let the files are
download and finish) and then

Run your app that is done it will launch your emulator and configure it then run it!

That is it!!! Happy Coding guys!!!!!!!

I've solved the problem by copying both

• Microsoft.ReportViewer.WebForms.dll from C:\Program Files (x86)\Microsoft Visual Studio 12.0\ReportViewer
• and Microsoft.reportviewer.common.dll from C:\Program Files\Microsoft Office\Office15\ADDINS\PowerPivot Excel Add-in

into bin folder (website).

Of course web.config must have:

    <httpHandlers>
        <add path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" validate="false" />
    </httpHandlers>

    <assemblies>

        <add assembly="Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845DCD8080CC91" />
        <add assembly="Microsoft.ReportViewer.Common, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845DCD8080CC91" />
    </assemblies>

    <buildProviders>
        <add extension=".rdlc" type="Microsoft.Reporting.RdlBuildProvider, Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
    </buildProviders>

    <system.webServer>
        <validation validateIntegratedModeConfiguration="false" />
        <handlers>
            <add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
        </handlers>
    </system.webServer>

And that's all. For me is ok.

Hope this helps.

Update 2016:

GCM is being replaced with FCM

• FAQ about the replacement
• Documentation

Update 2015:

Have a look at developers.android.com - Google replaced C2DM with GCM Demo Implementation / How To

Update 2014:

1) You need to check on the server what HTTP response you are getting from the Google servers. Make sure it is a 200 OK response, so you know the message was sent. If you get another response (302, etc) then the message is not being sent successfully.

2) You also need to check that the Registration ID you are using is correct. If you provide the wrong Registration ID (as a destination for the message - specifying the app, on a specific device) then the Google servers cannot successfully send it.

3) You also need to check that your app is successfully registering with the Google servers, to receive push notifications. If the registration fails, you will not receive messages.

First Answer 2014

Here is a good question you may should have a look at it: How to add a push notification in my own android app

Also here is a good blog with a really simple how to: http://blog.serverdensity.com/android-push-notifications-tutorial/

I changed color programmatically in this way :

var builder = new AlertDialog.Builder (this);
...
...
...
var dialog = builder.Show ();
int textColorId = Resources.GetIdentifier ("alertTitle", "id", "android");
TextView textColor = dialog.FindViewById<TextView> (textColorId);
textColor?.SetTextColor (Color.DarkRed);

as alertTitle, you can change other data by this way (next example is for titleDivider):

int titleDividerId = Resources.GetIdentifier ("titleDivider", "id", "android");
View titleDivider = dialog.FindViewById (titleDividerId);
titleDivider?.SetBackgroundColor (Color.Red);

this is in C#, but in java it is the same.

Supposing that you are using ECLIPSE:

Right click PROJECT PROPERTIES ANDROID

If you have a version of ANDROID checked, you must change it to a GOOGLE API. Choose a version of GOOGLE APIS compatible with your project's target version.

You concrete problem is caused because you're mixing discouraged and old school scriptlets <% %> with its successor EL ${}. They do not share the same variable scope. The allFestivals is not available in scriptlet scope and the i is not available in EL scope.

You should install JSTL (<-- click the link for instructions) and declare it in top of JSP as follows:

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

and then iterate over the list as follows:

<c:forEach items="${allFestivals}" var="festival">
    <tr>      
        <td>${festival.festivalName}</td>
        <td>${festival.location}</td>
        <td>${festival.startDate}</td>
        <td>${festival.endDate}</td>
        <td>${festival.URL}</td>  
    </tr>
</c:forEach>

(beware of possible XSS attack holes, use <c:out> accordingly)

Don't forget to remove the <jsp:useBean> as it has no utter value here when you're using a servlet as model-and-view controller. It would only lead to confusion. See also our servlets wiki page. Further you would do yourself a favour to disable scriptlets by the following entry in web.xml so that you won't accidently use them:

<jsp-config>
    <jsp-property-group>
        <url-pattern>*.jsp</url-pattern>
        <scripting-invalid>true</scripting-invalid>
    </jsp-property-group>
</jsp-config>

In order to start a service in its own process, you must specify the following in the xml declaration.

<service
  android:name="WordService"
  android:process=":my_process" 
  android:icon="@drawable/icon"
  android:label="@string/service_name"
  >
</service>

Run these codes in thread or AsyncTask. In order to avoid duplicated callings of same _url(one time for getContentLength(), one time of openStream()), use IOUtils.toByteArray of Apache.

void downloadFile(String _url, String _name) {
    try {
        URL u = new URL(_url);
        DataInputStream stream = new DataInputStream(u.openStream());
        byte[] buffer = IOUtils.toByteArray(stream);
        FileOutputStream fos = mContext.openFileOutput(_name, Context.MODE_PRIVATE);
        fos.write(buffer);
        fos.flush();
        fos.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
        return;
    } catch (IOException e) {
        e.printStackTrace();
        return;
    }
}

Add a broadcast receiver which can listen to network connectivity change. Then check wether device is connected to internet or not using ConnectivityManager. Refer to this post or video for detailed understanding. Below is the code:

public class NetworkStateChangeReceiver extends BroadcastReceiver {
  public static final String NETWORK_AVAILABLE_ACTION = "com.ajit.singh.NetworkAvailable";
  public static final String IS_NETWORK_AVAILABLE = "isNetworkAvailable";

  @Override
  public void onReceive(Context context, Intent intent) {
    Intent networkStateIntent = new Intent(NETWORK_AVAILABLE_ACTION);
    networkStateIntent.putExtra(IS_NETWORK_AVAILABLE,  isConnectedToInternet(context));
    LocalBroadcastManager.getInstance(context).sendBroadcast(networkStateIntent);
  }

  private boolean isConnectedToInternet(Context context) {
    try {
      if (context != null) {
        ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
        return networkInfo != null && networkInfo.isConnected();
      }
      return false;
    } catch (Exception e) {
      Log.e(NetworkStateChangeReceiver.class.getName(), e.getMessage());
      return false;
    }
  }
}

I wrote this receiver to show a notification on the Screen, that's why you see a local broadcast with the network status. Here is the code to show the notification.

public class MainActivity extends AppCompatActivity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    IntentFilter intentFilter = new IntentFilter(NetworkStateChangeReceiver.NETWORK_AVAILABLE_ACTION);
    LocalBroadcastManager.getInstance(this).registerReceiver(new BroadcastReceiver() {
      @Override
      public void onReceive(Context context, Intent intent) {
        boolean isNetworkAvailable = intent.getBooleanExtra(IS_NETWORK_AVAILABLE, false);
        String networkStatus = isNetworkAvailable ? "connected" : "disconnected";

        Snackbar.make(findViewById(R.id.activity_main), "Network Status: " + networkStatus, Snackbar.LENGTH_LONG).show();
      }
    }, intentFilter);
  }
}

Activity listens to the intent broadcasted by the network receiver and shows the notification on the screen.

To create a DLL File, click on New project, then select Class Library.

Enter your code into the class file that was automatically created for you and then click Build Solution from the Debug menu.

Now, look in your directory: ../debug/release/YOURDLL.dll

There it is! :)

P.S. DLL files cannot be run just like normal applciation (exe) files. You'll need to create a separate project (probably a win forms app) and then add your dll file to that project as a "Reference", you can do this by going to the Solution explorer, right clicking your project Name and selecting Add Reference then browsing to whereever you saved your dll file.

For more detail please click HERE

private MyPhoneStateListener phoneStateListener = new MyPhoneStateListener();

to register

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);

and to unregister

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_NONE);

if you use fragment u should use

getActivity().onBackPressed();

if you use single activity u can use

finish();

1. Go to http://www.nuget.org
2. Search for desired package. For example: Microsoft.Owin.Host.SystemWeb
3. Download the package by clicking the Download link on the left.
4. Do step 3 for the dependencies which are not already installed.
5. Store all downloaded packages in a custom folder. The default is c:\Package source.
6. Open Nuget Package Manager in Visual Studio and make sure you have an "Available package source" that points to the specified address in step 5; If not, simply add one by providing a custom name and address. Click OK.
7. At this point you should be able to install the package exactly the same way you would install an online package through the interface. You probably won't be able to install the package using NuGet console.

I had the same issue, ended up using the much more convenient Guava Resources:

Resources.getResource("my.file")

This usually works as well :)

navigateUpTo(new Intent(getBaseContext(), MainActivity.class));

 this.requestWindowFeature(getWindow().FEATURE_NO_TITLE);

In your res/values/styles.xml of modern Android Studio projects (2019/2020) you should be able to change the default parent theme

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

I went one step further and had it look like this

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:windowFullscreen">true</item>
</style>

This is based on the code generated from the Microsoft PWA builder https://www.pwabuilder.com/

Do not bother with encoding. Use a text node instead. Data in text node is guaranteed to be treated as text.

document.body.appendChild(document.createTextNode("Your&funky<text>here"))

I had the same issue with Instantiating DBContext object from a unit test project. I checked my unit test project packages and I figured that EntityFramework package was not installed, I installed that from Nuget and problem solved (I think it's EF bug).

happy coding

StopWatch class looks for your best solution.

Stopwatch sw = Stopwatch.StartNew();
DoSomeWork();
sw.Stop();

Console.WriteLine("Time taken: {0}ms", sw.Elapsed.TotalMilliseconds);

Also it has a static field called Stopwatch.IsHighResolution. Of course, this is a hardware and operating system issue.

Indicates whether the timer is based on a high-resolution performance counter.

There is no way to completely avoid reverse engineering of an APK. To protect application assets, resources, you can use encryption.

• Encryption will make harder to use it without decryption.choosing some strong encryption algorithm will make cracking harder.
• Adding some spoof code into your main logic to make more harder for cracking.
• If you can write your critical logic in any native language and that surely make harder for decompile.
• Using any third party security frameworks like Quixxi

In Eclipse:

Window -> Preferences -> Android -> Lint Error Checking.

In the list find an entry with ID = ProtectedPermission. Set the Severity to something lower than Error. This way you can still compile the project using Eclipse.

In Android Studio:

File -> Settings -> Editor -> Inspections

Under Android Lint, locate Using system app permission. Either uncheck the checkbox or choose a Severity lower than Error.

Maybe You must highlight this :

Note: Google Play services is not supported on the Android emulator — to develop using the APIs, you need to provide a development device such as an Android phone or tablet.

http://developer.android.com/google/play-services/setup.html

You must provide a physical development device on which you can run and debug your app. Do not use emulator. Will not working.

I had the exact same issue and i just needed to set the SDK for the library project of the MapsApiV2 to Android 2.3.3 (API lvl 10)

I solved these problem by doing the following steps:

• In Emulator:

  You have to use the latest API Google APIs(Google Inc.)-API Level 19.

  Do the rest of the things placed in the screenshot itself.

  

• API Key:

  Create New API Key and Check carefully about Google Map API key and SHA Key.

• Google Play Services:

  You have to download the latest Google Play Services com.android.vending-4.8.20.apk.In that site if google play services wasn't working means you can find a lot of sites in internet named com.android.vending 4.8.20.apk.

  you can run the Google play Services by using the Command Prompt adb install com.android.vending 4.8.20.apk.

  Note: You have to download the latest Google play services because year by year latest version will be updated in internet.

  output:

  

This is fairly easy on processing power required:

(string1(.|\n)*string2)|(string2(.|\n)*string1)

I used this in visual studio 2013 to find all files that had both string 1 and 2 in it.

I know this is really old, but this is the simplest way to query for Map.

Simply implement the ResultSetExtractor interface to define what type you want to return. Below is an example of how to use this. You'll be mapping it manually, but for a simple map, it should be straightforward.

jdbcTemplate.query("select string1,string2 from table where x=1", new ResultSetExtractor<Map>(){
    @Override
    public Map extractData(ResultSet rs) throws SQLException,DataAccessException {
        HashMap<String,String> mapRet= new HashMap<String,String>();
        while(rs.next()){
            mapRet.put(rs.getString("string1"),rs.getString("string2"));
        }
        return mapRet;
    }
});

This will give you a return type of Map that has multiple rows (however many your query returned) and not a list of Maps. You can view the ResultSetExtractor docs here: http://docs.spring.io/spring-framework/docs/2.5.6/api/org/springframework/jdbc/core/ResultSetExtractor.html

My bible for JPA work is the Java Persistence wikibook. It has a section on unidirectional OneToMany which explains how to do this with a @JoinColumn annotation. In your case, i think you would want:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE")
private Set<Text> text;

I've used a Set rather than a List, because the data itself is not ordered.

The above is using a defaulted referencedColumnName, unlike the example in the wikibook. If that doesn't work, try an explicit one:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE", referencedColumnName="DATREG_META_CODE")
private Set<Text> text;

the $("body").append(r) statement should be within the test function, also there was misplaced " in the test method

function test() {
    var r=$('<input/>').attr({
        type: "button",
        id: "field",
        value: 'new'
    });
    $("body").append(r);    
}

Demo: Fiddle

Update
In that case try a more jQuery-ish solution

<!DOCTYPE html>
<html>
    <head>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
        <script type="text/javascript">
          jQuery(function($){
              $('#mybutton').one('click', function(){
                  var r=$('<input/>').attr({
                      type: "button",
                      id: "field",
                      value: 'new'
                  });
                  $("body").append(r);   
              })
          })
        </script>

    <body>
        <button id="mybutton">Insert after</button>

The use of transition: none seems to be supported (with a specific adjustment for Opera) given the following HTML:

<a href="#" class="transition">Content</a>
<a href="#" class="transition">Content</a>
<a href="#" class="noTransition">Content</a>
<a href="#" class="transition">Content</a>

...and CSS:

a {
    color: #f90;
    -webkit-transition:color 0.8s ease-in, background-color 0.1s ease-in ;  
    -moz-transition:color 0.8s ease-in, background-color 0.1s ease-in;  
    -o-transition:color 0.8s ease-in, background-color 0.1s ease-in;  
    transition:color 0.8s ease-in, background-color 0.1s ease-in; 
}
a:hover {
    color: #f00;
    -webkit-transition:color 0.8s ease-in, background-color 0.1s ease-in ;  
    -moz-transition:color 0.8s ease-in, background-color 0.1s ease-in;  
    -o-transition:color 0.8s ease-in, background-color 0.1s ease-in;  
    transition:color 0.8s ease-in, background-color 0.1s ease-in; 
}
a.noTransition {
    -moz-transition: none;
    -webkit-transition: none;
    -o-transition: color 0 ease-in;
    transition: none;
}

JS Fiddle demo.

Tested with Chromium 12, Opera 11.x and Firefox 5 on Ubuntu 11.04.

The specific adaptation to Opera is the use of -o-transition: color 0 ease-in; which targets the same property as specified in the other transition rules, but sets the transition time to 0, which effectively prevents the transition from being noticeable. The use of the a.noTransition selector is simply to provide a specific selector for the elements without transitions.

Edited to note that @Frédéric Hamidi's answer, using all (for Opera, at least) is far more concise than listing out each individual property-name that you don't want to have transition.

Updated JS Fiddle demo, showing the use of all in Opera: -o-transition: all 0 none, following self-deletion of @Frédéric's answer.

If we use msvc or Qt (up to Qt 4.5), since GCC(up to 3.4) , msvc both support #pragma once, I can see no reason for not using #pragma once.

Source file name usually same equal class name, and we know, sometime we need refactor, to rename class name, then we had to change the #include XXXX also, so I think manual maintain the #include xxxxx is not a smart work. even with Visual Assist X extension, maintain the "xxxx" is not a necessary work.

So use the client-side loop to build a two-dimensional array of your arrays, and send the entire thing to PHP in one request.

Server-side, you'll need to have another loop which does its regular insert/update for each sub-array.

To answer your second query re. how encoding works, Joel Spolsky wrote a great introductory article on this. Strongly recommended.

Solution with ActiveRoute (if you want pass object by route - use JSON.stringfy/JSON.parse):

Prepare object before sending:

export class AdminUserListComponent {

  users : User[];

  constructor( private router : Router) { }

  modifyUser(i) {

    let navigationExtras: NavigationExtras = {
      queryParams: {
          "user": JSON.stringify(this.users[i])
      }
    };

    this.router.navigate(["admin/user/edit"],  navigationExtras);
  }

}

Receive your object in destination component:

export class AdminUserEditComponent  {

  userWithRole: UserWithRole;      

  constructor( private route: ActivatedRoute) {}

  ngOnInit(): void {
    super.ngOnInit();

      this.route.queryParams.subscribe(params => {
        this.userWithRole.user = JSON.parse(params["user"]);
      });
  }

}

The fork(),vfork() and clone() all call the do_fork() to do the real work, but with different parameters.

asmlinkage int sys_fork(struct pt_regs regs)
{
    return do_fork(SIGCHLD, regs.esp, &regs, 0);
}

asmlinkage int sys_clone(struct pt_regs regs)
{
    unsigned long clone_flags;
    unsigned long newsp;

    clone_flags = regs.ebx;
    newsp = regs.ecx;
    if (!newsp)
        newsp = regs.esp;
    return do_fork(clone_flags, newsp, &regs, 0);
}
asmlinkage int sys_vfork(struct pt_regs regs)
{
    return do_fork(CLONE_VFORK | CLONE_VM | SIGCHLD, regs.esp, &regs, 0);
}
#define CLONE_VFORK 0x00004000  /* set if the parent wants the child to wake it up on mm_release */
#define CLONE_VM    0x00000100  /* set if VM shared between processes */

SIGCHLD means the child should send this signal to its father when exit.

For fork, the child and father has the independent VM page table, but since the efficiency, fork will not really copy any pages, it just set all the writeable pages to readonly for child process. So when child process want to write something on that page, an page exception happen and kernel will alloc a new page cloned from the old page with write permission. That's called "copy on write".

For vfork, the virtual memory is exactly by child and father---just because of that, father and child can't be awake concurrently since they will influence each other. So the father will sleep at the end of "do_fork()" and awake when child call exit() or execve() since then it will own new page table. Here is the code(in do_fork()) that the father sleep.

if ((clone_flags & CLONE_VFORK) && (retval > 0))
down(&sem);
return retval;

Here is the code(in mm_release() called by exit() and execve()) which awake the father.

up(tsk->p_opptr->vfork_sem);

For sys_clone(), it is more flexible since you can input any clone_flags to it. So pthread_create() call this system call with many clone_flags:

int clone_flags = (CLONE_VM | CLONE_FS | CLONE_FILES | CLONE_SIGNAL | CLONE_SETTLS | CLONE_PARENT_SETTID | CLONE_CHILD_CLEARTID | CLONE_SYSVSEM);

Summary: the fork(),vfork() and clone() will create child processes with different mount of sharing resource with the father process. We also can say the vfork() and clone() can create threads(actually they are processes since they have independent task_struct) since they share the VM page table with father process.

Specify the Line Number using NR built-in variable.

awk 'NR==1{print $1}' /etc/*release

I know this is a little old, but for anyone stumbling across this page should know there is a difference between \n and \r\n.

The \r\n gives a CRLF end of line and the \n gives an LF end of line character. There is very little difference to the eye in general.

Create a .txt from the string and then try and open in notepad (normal not notepad++) and you will notice the difference

SHA,PCT,PRACTICE,BNF CODE,BNF NAME,ITEMS,NIC,ACT COST,QUANTITY,PERIOD
Q44,01C,N81002,0101021B0AAALAL,Sod Algin/Pot Bicarb_Susp S/F,3,20.48,19.05,2000,201901

The above is using 'CRLF' and the below is what 'LF only' would look like (There is a character that cant be seen where the LF shows).

SHA,PCT,PRACTICE,BNF CODE,BNF NAME,ITEMS,NIC,ACT COST,QUANTITY,PERIODQ44,01C,N81002,0101021B0AAALAL,Sod Algin/Pot Bicarb_Susp S/F,3,20.48,19.05,2000,201901Q44,01C,N81002,0101021B0AAAPAP,Sod Alginate/Pot Bicarb_Tab Chble 500mg,1,3.07,2.86,60,201901

If the Line Ends need to be corrected and the file is small enough in size, you can change the line endings in NotePad++ (or paste into word then back into Notepad - although this will make CRLF only).

This may cause some functions that read these files to potenitially no longer function (The example lines given are from GP Prescribing data - England. The file has changed from a CRLF Line end to an LF line end). This stopped an SSIS job from running and failed as couldn't read the LF line endings.

Source of Line Ending Information: https://en.wikipedia.org/wiki/Newline#Representations_in_different_character_encoding_specifications

Hope this helps someone in future :) CRLF = Windows based, LF or CF are from Unix based systems (Linux, MacOS etc.)

I would recommend EasyInstall, a package management application for Python.

Once you've installed EasyInstall, you should be able to go to a command window and type:

easy_install simplejson

This may require putting easy_install.exe on your PATH first, I don't remember if the EasyInstall setup does this for you (something like C:\Python25\Scripts).

Would this CSS fix it?

iframe {
    display:block;
    width:100%;
}

From this example: http://jsfiddle.net/HNyJS/2/show/

It's not clear to me what you want, but I'll mention that the Date class also has a compareTo method, which can be used to determine with one call if two Date objects are equal or (if they aren't equal) which occurs sooner. This allows you to do something like:

switch (today.compareTo(questionDate)) {
    case -1:  System.out.println("today is sooner than questionDate");  break;
    case 0:   System.out.println("today and questionDate are equal");  break;
    case 1:   System.out.println("today is later than questionDate");  break;
    default:  System.out.println("Invalid results from date comparison"); break;
}

It should be noted that the API docs don't guarantee the results to be -1, 0, and 1, so you may want to use if-elses rather than a switch in any production code. Also, if the second date is null, you'll get a NullPointerException, so wrapping your code in a try-catch may be useful.

You can remove the time component when comparing:

SELECT * 
FROM sales 
WHERE CONVERT(DATETIME, FLOOR(CONVERT(FLOAT, salesDate))) = '11/11/2010'

Another approach is to change the select to cover all the time between the start and end of the date:

SELECT * 
FROM sales 
-- WHERE salesDate BETWEEN '11/11/2010 00:00:00.00' AND '11/11/2010 23:59:59.999'
WHERE salesDate BETWEEN '2020-05-18T00:00:00.00' AND '2020-05-18T23:59:59.999'

A simple hack to keep the window open:

counter = 0

While (True):

    If (counter == 0):

        # Code goes here

    counter += 1

The counter is so the code won’t repeat itself.

Since "$(this).parent().index();" and "$(this).parent('table').index();" don't work for me, I use this code instead:

$('td').click(function(){
   var row_index = $(this).closest("tr").index();
   var col_index = $(this).index();
});

Assuming the connection is established and is available in global scope;

//Check if a value exists in a table
function record_exists ($table, $column, $value) {
    global $connection;
    $query = "SELECT * FROM {$table} WHERE {$column} = {$value}";
    $result = mysql_query ( $query, $connection );
    if ( mysql_num_rows ( $result ) ) {
        return TRUE;
    } else {
        return FALSE;
    }
}

Usage: Assuming that the value to be checked is stored in the variable $username;

if (record_exists ( 'employee', 'username', $username )){
    echo "Username is not available. Try something else.";
} else {
    echo "Username is available";
}

For flutter projects you can also solve this issue

open your \android\app\build.gradle

you sould have the following:

android {
    defaultConfig {
        ...
        minSdkVersion 16
        targetSdkVersion 28

    }

}

If your minSdkVersion is set to 21 or higher, all you need to do is set multiDexEnabled to true in the defaultConfig. Like this

android {
    defaultConfig {
        ...
        minSdkVersion 16
        targetSdkVersion 28
        multiDexEnabled true 

    }

}

if your minSdkVersion is set to 20 or lower add multiDexEnabled true to the defaultConfig

And define the implementation

dependencies {
  implementation 'com.android.support:multidex:1.0.3'// or 2.0.1
}

At the end you should have:

android {
    defaultConfig {
        ...
        minSdkVersion 16
        targetSdkVersion 28
        multiDexEnabled true  // added this
    }

}

dependencies {
  implementation 'com.android.support:multidex:1.0.3'
}

Simply, static functions function independently of the class where they belong.

$this means, this is an object of this class. It does not apply to static functions.

class test {
    public function sayHi($hi = "Hi") {
        $this->hi = $hi;
        return $this->hi;
    }
}
class test1 {
    public static function sayHi($hi) {
        $hi = "Hi";
        return $hi;
    }
}

//  Test
$mytest = new test();
print $mytest->sayHi('hello');  // returns 'hello'
print test1::sayHi('hello');    //  returns 'Hi'

a_list = []
b_list = []
for i in range(1,100):
    a_list.append(random.randint(1,100))

for i in range(1,100):
    a_list.append(random.randint(101,200))
[sum(x) for x in zip(a_list , b_list )]

Mecki's answer is absolutly perfect, but it's worth adding that FreeBSD also supports SO_REUSEPORT_LB, which mimics Linux' SO_REUSEPORT behaviour - it balances the load; see setsockopt(2)

If you need to store permanent path (path is not changed when cmd is restart)

1. Run the Command Prompt as administrator (Right click on cmd.exe and select run as administrator)

2. In cmd setx path "%path%;your new path" then enter

3. Check whether the path is taken correctly by typing path and pressing enter

Try setting the system default encoding as utf-8 at the start of the script, so that all strings are encoded using that.

Example -

import sys
reload(sys)
sys.setdefaultencoding('utf-8')

The above should set the default encoding as utf-8 .

insert into TABLENAMEA (A,B,C,D) 
select A::integer,B,C,D from TABLENAMEB

execute the below code to get the foreign key constraint name which blocks your drop. For example, I take the roles table.

      SELECT *
      FROM sys.foreign_keys
      WHERE referenced_object_id = object_id('roles');

      SELECT name AS 'Foreign Key Constraint Name',
      OBJECT_SCHEMA_NAME(parent_object_id) + '.' + OBJECT_NAME(parent_object_id)
      AS 'Child Table' FROM sys.foreign_keys
      WHERE OBJECT_SCHEMA_NAME(referenced_object_id) = 'dbo'
      AND OBJECT_NAME(referenced_object_id) = 'dbo.roles'

you will get the FK name something as below : FK__Table1__roleId__1X1H55C1

now run the below code to remove the FK reference got from above.

ALTER TABLE dbo.users drop CONSTRAINT FK__Table1__roleId__1X1H55C1;

Done!

Sorry for digging out an old thread, but I think sunetos' answer isn't correct (or isn't the full answer). I've done some experiments (using ProcessStartInfo in c#) and it seems that the 'arguments' string for a commandline command is limited to 2048 characters in XP and 32768 characters in Win7. I'm not sure what the 8191 limit refers to, but I haven't found any evidence of it yet.

There are two methods by which you can round up your double value.

1. Math.ceil
2. Math.floor

If you want your answer 4.90625 as 4 then you should use Math.floor and if you want your answer 4.90625 as 5 then you can use Math.ceil

You can refer following code for that.

public class TestClass {

    public static void main(String[] args) {
        int floorValue = (int) Math.floor((double)157 / 32);
        int ceilValue = (int) Math.ceil((double)157 / 32);
        System.out.println("Floor: "+floorValue);
        System.out.println("Ceil: "+ceilValue);

    }

}

function isNumber(n) {
  return !isNaN(parseFloat(n)) && isFinite(n);
}

When you use df.apply(), each row of your DataFrame will be passed to your lambda function as a pandas Series. The frame's columns will then be the index of the series and you can access values using series[label].

So this should work:

df['D'] = (df.apply(lambda x: myfunc(x[colNames[0]], x[colNames[1]]), axis=1)) 

If you pushed a file or folder before it was in .gitignore (or had no .gitignore):

• Comment it out from .gitignore
• Add it back on the filesystem
• Remove it from the folder
• git add your file && commit it
• git push

I think the best way to implement enumeration like types is with symbols since the pretty much behave as integer (when it comes to performace, object_id is used to make comparisons ); you don't need to worry about indexing and they look really neat in your code xD

There's more to it than this, but you're probably looking for this list:

BM  business month end frequency
MS  month start frequency
BMS business month start frequency
Q   quarter end frequency
BQ  business quarter endfrequency
QS  quarter start frequency
BQS business quarter start frequency
A   year end frequency
BA  business year end frequency
AS  year start frequency
BAS business year start frequency
H   hourly frequency
T   minutely frequency
S   secondly frequency
L   milliseconds
U   microseconds

You can use a WScript object and call the Sleep method on it:

Set WScript = CreateObject("WScript.Shell")
WScript.Sleep 2000 'Sleeps for 2 seconds

Another option is to import and use the WinAPI function directly (only works in VBA, thanks @Helen):

Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sleep 2000

Simple example for compareAndSet() function:

import java.util.concurrent.atomic.AtomicInteger; 

public class GFG { 
    public static void main(String args[]) 
    { 

        // Initially value as 0 
        AtomicInteger val = new AtomicInteger(0); 

        // Prints the updated value 
        System.out.println("Previous value: "
                           + val); 

        // Checks if previous value was 0 
        // and then updates it 
        boolean res = val.compareAndSet(0, 6); 

        // Checks if the value was updated. 
        if (res) 
            System.out.println("The value was"
                               + " updated and it is "
                           + val); 
        else
            System.out.println("The value was "
                               + "not updated"); 
      } 
  } 

The printed is: previous value: 0 The value was updated and it is 6 Another simple example:

    import java.util.concurrent.atomic.AtomicInteger; 

public class GFG { 
    public static void main(String args[]) 
    { 

        // Initially value as 0 
        AtomicInteger val 
            = new AtomicInteger(0); 

        // Prints the updated value 
        System.out.println("Previous value: "
                           + val); 

         // Checks if previous value was 0 
        // and then updates it 
        boolean res = val.compareAndSet(10, 6); 

          // Checks if the value was updated. 
          if (res) 
            System.out.println("The value was"
                               + " updated and it is "
                               + val); 
        else
            System.out.println("The value was "
                               + "not updated"); 
    } 
} 

The printed is: Previous value: 0 The value was not updated

cliff.meyers's original answer that suggested using <env-entry> will not help when using only System.getProperty()

According to the Tomcat 6.0 docs <env-entry> is for JNDI. So that means it won't have any effect on System.getProperty().

With the <env-entry> from cliff.meyers's example, the following code

System.getProperty("SMTP_PASSWORD");

will return null, not the value "abc123ftw".

According to the Tomcat 6 docs, to use <env-entry> you'd have to write code like this to use <env-entry>:

// Obtain our environment naming context
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");

// Look up our data source
String s = (String)envCtx.lookup("SMTP_PASSWORD");

Caveat: I have not actually tried the example above. But I have tried <env-entry> with System.getProperty(), and that definitely does not work.

git branch --set-upstream <<origin/branch>> is officially not supported anymore and is replaced by git branch --set-upstream-to <<origin/branch>>

Use this javascript function as an example on how to accomplish this.

function isNoIframeOrIframeInMyHost() {
// Validation: it must be loaded as the top page, or if it is loaded in an iframe 
// then it must be embedded in my own domain.
// Info: IF top.location.href is not accessible THEN it is embedded in an iframe 
// and the domains are different.
var myresult = true;
try {
    var tophref = top.location.href;
    var tophostname = top.location.hostname.toString();
    var myhref = location.href;
    if (tophref === myhref) {
        myresult = true;
    } else if (tophostname !== "www.yourdomain.com") {
        myresult = false;
    }
} catch (error) { 
  // error is a permission error that top.location.href is not accessible 
  // (which means parent domain <> iframe domain)!
    myresult = false;
}
return myresult;
}

In nutshell: CANDIDATE KEY is a minimal SUPER KEY.

Where Super key is the combination of columns(or attributes) that uniquely identify any record(or tuple) in a relation(table) in RDBMS.

For instance, consider the following dependencies in a table having columns A, B, C, and D (Giving this table just for a quick example so not covering all dependencies that R could have).

Attribute set (Determinant)---Can Identify--->(Dependent)

A-----> AD

B-----> ABCD

C-----> CD

AC----->ACD

AB----->ABCD

ABC----->ABCD

BCD----->ABCD

Now, B, AB, ABC, BCD identifies all columns so those four qualify for the super key.

But, B?AB; B?ABC; B?BCD hence AB, ABC, and BCD disqualified for CANDIDATE KEY as their subsets could identify the relation, so they aren't minimal and hence only B is the candidate key, not the others.

One more thing Primary key is any one among the candidate keys.

Thanks for asking

Personal preference really. You could use const when, as you say, it will not be re-assigned and is constant. For example if you wanted to assign your birthday. Your birthday never changes so you could use it as a constant. But your age does change so that could be a variable.

As other users have pointed out, we use expression(). I'd like to answer the original question which involves a comma in the subscript:

How can I write v 1,2 with 1,2 as subscripts?

plot(1:10, 11:20 , main=expression(v["1,2"]))

Also, I'd like to add the reference for those looking to find the full expression syntax in R plotting: For more information see the ?plotmath help page. Running demo(plotmath) will showcase many expressions and relevant syntax.

Remember to use * to join different types of text within an expression.

Here is some of the sample output from demo(plotmath):

This file give you some more hints, for example, keydown.up doesn't work you need keydown.arrowup:

https://github.com/angular/angular/blob/630d93150a58581a0d474ebf1befb5d09b6813c5/modules/angular2/src/platform/browser/browser_adapter.dart

Use file_put_contents()

file_put_contents('file.txt', 'bar');
echo file_get_contents('file.txt'); // bar
file_put_contents('file.txt', 'foo');
echo file_get_contents('file.txt'); // foo

Alternatively, if you're stuck with fopen() you can use the w or w+ modes:

'w' Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

'w+' Open for reading and writing; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

My home-grown regular expression replace function can be used for this.

Demo

See this DB-Fiddle demo, which returns the second word ("I") from a famous sonnet and the number of occurrences of it (1).

SQL

Assuming MySQL 8 or later is being used (to allow use of a Common Table Expression), the following will return the second word and the number of occurrences of it:

WITH cte AS (
     SELECT digits.idx,
            SUBSTRING_INDEX(SUBSTRING_INDEX(words, '~', digits.idx + 1), '~', -1) word
     FROM
     (SELECT reg_replace(UPPER(txt),
                         '[^''’a-zA-Z-]+',
                         '~',
                         TRUE,
                         1,
                         0) AS words
      FROM tbl) delimited
     INNER JOIN
     (SELECT @row := @row + 1 as idx FROM 
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t1,
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t2, 
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t3, 
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t4, 
      (SELECT @row := -1) t5) digits
     ON LENGTH(REPLACE(words, '~' , '')) <= LENGTH(words) - digits.idx)
SELECT c.word,
       subq.occurrences
FROM cte c
LEFT JOIN (
  SELECT word,
         COUNT(*) AS occurrences
  FROM cte
  GROUP BY word
) subq
ON c.word = subq.word
WHERE idx = 1; /* idx is zero-based so 1 here gets the second word */

Explanation

A few tricks are used in the SQL above and some accreditation is needed. Firstly the regular expression replacer is used to replace all continuous blocks of non-word characters - each being replaced by a single tilda (~) character. Note: A different character could be chosen instead if there is any possibility of a tilda appearing in the text.

The technique from this answer is then used for transforming a string with delimited values into separate row values. It's combined with the clever technique from this answer for generating a table consisting of a sequence of incrementing numbers: 0 - 10,000 in this case.

In my case, this error ocurred while i was using the

implementation 'com.android.support:appcompat-v7:+'
implementation 'com.android.support:design:+'

libraries together with googles

implementation 'com.google.android.material:material-components:+'

library. If this is the case in your project, i highly recommend to fully remove the google material components library from your project.

Best answer:

$arr = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);

foreach ($arr as $a) {

// This is the line that does the checking
if (!each($arr)) echo "End!\n";

echo $a."\n";

}

Since this would be a common task I would suggest wrapping a switch/case inside of a function call.

function getVocationName($vocation){
    switch($vocation){
        case 1: return "Sorcerer";
        case 2: return 'Druid';
        case 3: return 'Paladin';
        case 4: return 'Knight';
        case 5: return 'Master Sorcerer';
        case 6: return 'Elder Druid';
        case 7: return 'Royal Paladin';
        default: return 'Elite Knight';
    }
}

echo getVocationName($result->vocation);

Currently, your enum is nested inside of your Card class. All you have to do is move the definition of the enum out of the class:

// A better name which follows conventions instead of card_suits is
public enum CardSuit
{
    Clubs,
    Hearts,
    Spades,
    Diamonds
}

public class Card
{
}

To Specify:

The name change from card_suits to CardSuit was suggested because Microsoft guidelines suggest Pascal Case for Enumerations and the singular form is more descriptive in this case (as a plural would suggest that you're storing multiple enumeration values by ORing them together).

Try this code:

CONVERT(varchar(15), date_started, 103)

try this:

SELECT * FROM OPENROWSET('SQLNCLI', 'Server=YOUR SERVER;Trusted_Connection=yes;','SELECT * FROM Table1') AS a
UNION
SELECT * FROM OPENROWSET('SQLNCLI', 'Server=ANOTHER SERVER;Trusted_Connection=yes;','SELECT * FROM Table1') AS a

100000 + Math.floor(Math.random() * 900000);

will give a number from 100000 to 999999 (inclusive).

You must have an empty line in your file.

You may want to wrap your parseInt calls in a "try" block:

try {
  tall[i++] = Integer.parseInt(s);
}
catch (NumberFormatException ex) {
  continue;
}

Or simply check for empty strings before parsing:

if (s.length() == 0) 
  continue;

Note that by initializing your index variable i inside the loop, it is always 0. You should move the declaration before the while loop. (Or make it part of a for loop.)

I need to select every production with a category that doesn't contain "Business"

Although I upvoted @Arran's answer as correct, I would also add this... Strictly interpreted, the OP's specification would be implemented as

//production[category[not(contains(., 'Business'))]]

rather than

//production[not(contains(category, 'Business'))]

The latter selects every production whose first category child doesn't contain "Business". The two XPath expressions will behave differently when a production has no category children, or more than one.

It doesn't make any difference in practice as long as every <production> has exactly one <category> child, as in your short example XML. Whether you can always count on that being true or not, depends on various factors, such as whether you have a schema that enforces that constraint. Personally, I would go for the more robust option, since it doesn't "cost" much... assuming your requirement as stated in the question is really correct (as opposed to e.g. 'select every production that doesn't have a category that contains "Business"').

try :

sudo su

then

npm i npx 
or 
npi i -g npx

check your npx version by

npx -v

Was looking for the solution of a similar problem. Thanks to the answer provided by Davlet and Cupcake I was able to solve my problem.

Posting this answer here since I think this is the intended question

So I guess generally the problem that people like me face is what to do when a repo is cloned by another user on a server and that user is no longer associated with the repo.

How to pull from the repo without using the credentials of the old user ?

You edit the .git/config file of your repo.

and change

url = https://<old-username>@github.com/abc/repo.git/

to

url = https://<new-username>@github.com/abc/repo.git/

After saving the changes, from now onwards git pull will pull data while using credentials of the new user.

I hope this helps anyone with a similar problem

The RFC for HTTP (as cited above) dictates that the headers are case-insensitive, however you will find that with certain browsers (I'm looking at you, IE) that capitalizing each of the words tends to be best:

Location: http://stackoverflow.com

Content-Type: text/plain

vs

location: http://stackoverflow.com

content-type: text/plain

This isn't "HTTP" standard, but just another one of the browser quirks, we as developers, have to think about.

GitPad sets your current text editor as the default editor for Git.

My default editor for .txt files in Windows 10 is Visual Studio Code and running GitPad once made it the default editor for Git. I haven't experienced the problems mentioned in the question (Git waits until VS Code window is closed in my case).

(The link for the .exe file didn't work for me, you may need to compile the source yourself.)

Did you try refreshing (right click -> refresh) the project folder after copying the file in there? That will SYNC your file system with Eclipse's internal file system.

When you run Eclipse projects, the CWD (current working directory) is project's root directory. Not bin's directory. Not src's directory, but the root dir.

Also, if you're in Linux, remember that its file systems are usually case sensitive.

I had the same issue in a Windows Service. All keys where in the right place in the registry. The build of the service was done for x86 and I still got the exception. I found out about CorFlags.exe

Run this on your service.exe without flags to verify if you run under 32 bit. If not run it with the flag /32BIT+ /Force (Force only for signed assemblies)

If you have UAC turned you can get the following error: corflags : error CF001 : Could not open file for writing Give the user full control on the assemblies.

Are you sure your web service is deployed correctly to the enviornment that is NOT working. Looks like the type is out of date.

In terms of coding, a bidirectional relationship is more complex to implement because the application is responsible for keeping both sides in synch according to JPA specification 5 (on page 42). Unfortunately the example given in the specification does not give more details, so it does not give an idea of the level of complexity.

When not using a second level cache it is usually not a problem to do not have the relationship methods correctly implemented because the instances get discarded at the end of the transaction.

When using second level cache, if anything gets corrupted because of wrongly implemented relationship handling methods, this means that other transactions will also see the corrupted elements (the second level cache is global).

A correctly implemented bi-directional relationship can make queries and the code simpler, but should not be used if it does not really make sense in terms of business logic.

As suggested in other answers it's probably easiest to "POST" the form data to the controller. If you need to pass an entire Model/Form you can easily do this with serialize() e.g.

$('#myform').on('submit', function(e){
    e.preventDefault();

    var formData = $(this).serialize();

    $.post('/student/update', formData, function(response){
         //Do something with response
    });
});

So your controller could have a view model as the param e.g.

 [HttpPost]
 public JsonResult Update(StudentViewModel studentViewModel)
 {}

Alternatively if you just want to post some specific values you can do:

$('#myform').on('submit', function(e){
    e.preventDefault();

    var studentId = $(this).find('#Student_StudentId');
    var isActive = $(this).find('#Student_IsActive');

    $.post('/my/url', {studentId : studentId, isActive : isActive}, function(response){
         //Do something with response
    });
});

With a controller like:

     [HttpPost]
     public JsonResult Update(int studentId, bool isActive)
     {}

status of 200 will be the default when using res.send, res.json, etc.

You can set the status like res.status(500).json({ error: 'something is wrong' });

Often I'll do something like...

router.get('/something', function(req, res, next) {
  // Some stuff here
  if(err) {
    res.status(500);
    return next(err);
  }
  // More stuff here
});

Then have my error middleware send the response, and do anything else I need to do when there is an error.

Additionally: res.sendStatus(status) has been added as of version 4.9.0 http://expressjs.com/4x/api.html#res.sendStatus

A DataSet already contains DataTables. You can just use:

DataTable firstTable = dataSet.Tables[0];

or by name:

DataTable customerTable = dataSet.Tables["Customer"];

Note that you should have using statements for your SQL code, to ensure the connection is disposed properly:

using (SqlConnection conn = ...)
{
    // Code here...
}

Added process.StartInfo.**CreateNoWindow** = true; and timeout.

private static void CaptureConsoleAppOutput(string exeName, string arguments, int timeoutMilliseconds, out int exitCode, out string output)
{
    using (Process process = new Process())
    {
        process.StartInfo.FileName = exeName;
        process.StartInfo.Arguments = arguments;
        process.StartInfo.UseShellExecute = false;
        process.StartInfo.RedirectStandardOutput = true;
        process.StartInfo.CreateNoWindow = true;
        process.Start();

        output = process.StandardOutput.ReadToEnd();

        bool exited = process.WaitForExit(timeoutMilliseconds);
        if (exited)
        {
            exitCode = process.ExitCode;
        }
        else
        {
            exitCode = -1;
        }
    }
}

Update: Google Forms can now upload files. This answer was posted before Google Forms had the capability to upload files.

This solution does not use Google Forms. This is an example of using an Apps Script Web App, which is very different than a Google Form. A Web App is basically a website, but you can't get a domain name for it. This is not a modification of a Google Form, which can't be done to upload a file.

NOTE: I did have an example of both the UI Service and HTML Service, but have removed the UI Service example, because the UI Service is deprecated.

NOTE: The only sandbox setting available is now IFRAME. I you want to use an onsubmit attribute in the beginning form tag: <form onsubmit="myFunctionName()">, it may cause the form to disappear from the screen after the form submission.

If you were using NATIVE mode, your file upload Web App may no longer be working. With NATIVE mode, a form submission would not invoke the default behavior of the page disappearing from the screen. If you were using NATIVE mode, and your file upload form is no longer working, then you may be using a "submit" type button. I'm guessing that you may also be using the "google.script.run" client side API to send data to the server. If you want the page to disappear from the screen after a form submission, you could do that another way. But you may not care, or even prefer to have the page stay on the screen. Depending upon what you want, you'll need to configure the settings and code a certain way.

If you are using a "submit" type button, and want to continue to use it, you can try adding event.preventDefault(); to your code in the submit event handler function. Or you'll need to use the google.script.run client side API.

A custom form for uploading files from a users computer drive, to your Google Drive can be created with the Apps Script HTML Service. This example requires writing a program, but I've provide all the basic code here.

This example shows an upload form with Google Apps Script HTML Service.

What You Need

• Google Account
• Google Drive
• Google Apps Script - also called Google Script

Google Apps Script

There are various ways to end up at the Google Apps Script code editor.

• Load Apps Script directly from the web address: https://script.google.com
• Open a Google Sheet first, then open Apps Script
• Go to your Google Drive, then Open Apps Script: https://drive.google.com/drive/#my-drive
• Go to your Google Drive, then click on an Apps Script project file
• Open Apps Script from Google Docs
• etc

I mention this because if you are not aware of all the possibilities, it could be a little confusing. Google Apps Script can be embedded in a Google Site, Sheets, Docs or Forms, or used as a stand alone app.

Apps Script Overview

This example is a "Stand Alone" app with HTML Service.

HTML Service - Create a web app using HTML, CSS and Javascript

Google Apps Script only has two types of files inside of a Project:

• Script
• HTML

Script files have a .gs extension. The .gs code is a server side code written in JavaScript, and a combination of Google's own API.

• Copy and Paste the following code

• Save It

• Create the first Named Version

• Publish it

• Set the Permissions

  and you can start using it.

Start by:

• Create a new Blank Project in Apps Script
• Copy and Paste in this code:

Upload a file with HTML Service:

Code.gs file (Created by Default)

//For this to work, you need a folder in your Google drive named:
// 'For Web Hosting'
// or change the hard coded folder name to the name of the folder
// you want the file written to

function doGet(e) {
  return HtmlService.createTemplateFromFile('Form')
    .evaluate() // evaluate MUST come before setting the Sandbox mode
    .setTitle('Name To Appear in Browser Tab')
    .setSandboxMode();//Defaults to IFRAME which is now the only mode available
}

function processForm(theForm) {
  var fileBlob = theForm.picToLoad;
  
  Logger.log("fileBlob Name: " + fileBlob.getName())
  Logger.log("fileBlob type: " + fileBlob.getContentType())
  Logger.log('fileBlob: ' + fileBlob);

  var fldrSssn = DriveApp.getFolderById(Your Folder ID);
    fldrSssn.createFile(fileBlob);
    
  return true;
}

Create an html file:

<!DOCTYPE html>
<html>
  <head>
    <base target="_top">
  </head>
  <body>
    <h1 id="main-heading">Main Heading</h1>
    <br/>
    <div id="formDiv">

      <form id="myForm">
    
        <input name="picToLoad" type="file" /><br/>
        <input type="button" value="Submit" onclick="picUploadJs(this.parentNode)" />
          
      </form>
    </div>


  <div id="status" style="display: none">
  <!-- div will be filled with innerHTML after form submission. -->
  Uploading. Please wait...
</div>

</body>
<script>

function picUploadJs(frmData) {

  document.getElementById('status').style.display = 'inline';

  google.script.run
    .withSuccessHandler(updateOutput)
    .processForm(frmData)
};
  // Javascript function called by "submit" button handler,
  // to show results.
  
  function updateOutput() {
  
    var outputDiv = document.getElementById('status');
    outputDiv.innerHTML = "The File was UPLOADED!";
  }

</script>
</html>

This is a full working example. It only has two buttons and one <div> element, so you won't see much on the screen. If the .gs script is successful, true is returned, and an onSuccess function runs. The onSuccess function (updateOutput) injects inner HTML into the div element with the message, "The File was UPLOADED!"

• Save the file, give the project a name
• Using the menu: File, Manage Version then Save the first Version
• Publish, Deploy As Web App then Update

When you run the Script the first time, it will ask for permissions because it's saving files to your drive. After you grant permissions that first time, the Apps Script stops, and won't complete running. So, you need to run it again. The script won't ask for permissions again after the first time.

The Apps Script file will show up in your Google Drive. In Google Drive you can set permissions for who can access and use the script. The script is run by simply providing the link to the user. Use the link just as you would load a web page.

Another example of using the HTML Service can be seen at this link here on StackOverflow:

File Upload with HTML Service

NOTES about deprecated UI Service:

There is a difference between the UI Service, and the Ui getUi() method of the Spreadsheet Class (Or other class) The Apps Script UI Service was deprecated on Dec. 11, 2014. It will continue to work for some period of time, but you are encouraged to use the HTML Service.

Google Documentation - UI Service

Even though the UI Service is deprecated, there is a getUi() method of the spreadsheet class to add custom menus, which is NOT deprecated:

Spreadsheet Class - Get UI method

I mention this because it could be confusing because they both use the terminology UI.

The UI method returns a Ui return type.

You can add HTML to a UI Service, but you can't use a <button>, <input> or <script> tag in the HTML with the UI Service.

Here is a link to a shared Apps Script Web App file with an input form:

Shared File - Contact Form

you want something like:

SELECT count(id), SUM(hour) as totHour, SUM(kind=1) as countKindOne;

Note that your second example was close, but the IF() function always takes three arguments, so it would have had to be COUNT(IF(kind=1,1,NULL)). I prefer the SUM() syntax shown above because it's concise.

• s1.CompareTo(s2): Do NOT use if primary purpose is to determine whether two strings are equivalent
• s1 == s2: Cannot ignore case
• s1.Equals(s2, StringComparison): Throws NullReferenceException if s1 is null
• String.Equals(s2, StringComparison): By process of eliminiation, this static method is the WINNER (assuming a typical use case to determine whether two strings are equivalent)!

Latest and greatest way to do this:

Node supports file and buffer operations with the base64 encoding:

const fs = require('fs');
const contents = fs.readFileSync('/path/to/file.jpg', {encoding: 'base64'});

Or using the new promises API:

const fs = require('fs').promises;
const contents = await fs.readFile('/path/to/file.jpg', {encoding: 'base64'});

With the example class you posted it doesn't seem to make much sense to test getFuel() and getSpeed() since they can only return 0 (there are no setters).

However, assuming that this was just a simplified example for illustrative purposes, and that you have legitimate reasons to test methods in the abstract base class (others have already pointed out the implications), you could setup your test code so that it creates an anonymous subclass of the base class that just provides dummy (no-op) implementations for the abstract methods.

For example, in your TestCase you could do this:

c = new Car() {
       void drive() { };
   };

Then test the rest of the methods, e.g.:

public class CarTest extends TestCase
{
    private Car c;

    public void setUp()
    {
        c = new Car() {
            void drive() { };
        };
    }

    public void testGetFuel() 
    {
        assertEquals(c.getFuel(), 0);
    }

    [...]
}

(This example is based on JUnit3 syntax. For JUnit4, the code would be slightly different, but the idea is the same.)

I suppose because you didn't specify plugin version so it triggers the download of associated metadata in order to get the last one.

Otherwise did you try to force local repo usage using -o ?

use this for fixing issue with shadow box

filter: progid:DXImageTransform.Microsoft.dropShadow (OffX='2', OffY='2', Color='#F13434', Positive='true');

sys.argv[1] contains the first command line argument passed to your script.

For example, if your script is named hello.py and you issue:

$ python3.1 hello.py foo

or:

$ chmod +x hello.py  # make script executable
$ ./hello.py foo

Your script will print:

Hello there foo

It very much depend on the program you're using. Different programs (Emacs, vi, sed, and Perl) use slightly different regular expressions. In this case, I'd say that in the first pattern, the last "+" should be removed.

hibernate.jar and hibernate-entitymanager.jar contains only the packages org.hibernate.*. So you should take it from the Glassfish project.

Use json in dataType and send like this:

    $.ajax({
        url: "your url which return json",
        type: "POST",
        crossDomain: true,
        data: data,
        dataType: "json",
        success:function(result){
            alert(JSON.stringify(result));
        },
        error:function(xhr,status,error){
            alert(status);
        }
    });

and put this lines in your server side file:

if PHP:

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST');
header('Access-Control-Max-Age: 1000');

if java:

response.addHeader( "Access-Control-Allow-Origin", "*" ); 
response.addHeader( "Access-Control-Allow-Methods", "POST" ); 
response.addHeader( "Access-Control-Max-Age", "1000" );

Needed to leverage reader to convert blob to base64, prefer to use async-await syntax so I chose to extract reader logic into helper like this:

//* Convert resBlob to base64
export const blobToData = (blob: Blob) => {
  return new Promise((resolve) => {
    const reader = new FileReader()
    reader.onloadend = () => resolve(reader.result)
    reader.readAsDataURL(blob)
  })
}

and calling it using await in main code:

//* Convert resBlob to dataUrl and resolve
const resData = await blobToData(resBlob)

Figured it out for myself in the end. It is simple, I was just missing the ** operator to unpack the dictionary

So my example becomes:

d = dict(p1=1, p2=2)
def f2(p1,p2):
    print p1, p2
f2(**d)

With Calendar it works as follows:

    //create first Calendar object
    Calendar calendar = Calendar.getInstance();

    calendar.set(Calendar.HOUR_OF_DAY, 15); // 3 PM
    // the same is
    calendar.set(Calendar.AM_PM, Calendar.PM); // choose PM mode
    calendar.set(Calendar.HOUR, 3); // 3 PM

    System.out.println( calendar.get(Calendar.HOUR) ); // AM_PM format
    System.out.println( calendar.get(Calendar.HOUR_OF_DAY) ); // 0-23 format

@echo off

        if %%x==SERVER_IS_UP (set SERVER_STATE=UP) else (set SERVER_STATE=DOWN)
    )

1. Resource description “Resources” refers to the information returned by an API.

2. Endpoints and methods The endpoints indicate how you access the resource, while the method indicates the allowed interactions (such as GET, POST, or DELETE) with the resource.

Additional info: 3. Parameters Parameters are options you can pass with the endpoint (such as specifying the response format or the amount returned) to influence the response.

4. Request example The request example includes a sample request using the endpoint, showing some parameters configured.

5. Response example and schema The response example shows a sample response from the request example; the response schema defines all possible elements in the response.

From http://www.powershellmagazine.com/2012/07/24/jaap-brassers-favorite-powershell-tips-and-tricks/:

Get-ChildItem –Force –Recurse –ErrorAction SilentlyContinue –ErrorVariable AccessDenied

the first part just iterates through this and sub-folders; using -ErrorVariable AccessDenied means push the offending items into the powershell variable AccessDenied.

You can then scan through the variable like so

$AccessDenied |
Where-Object { $_.Exception -match "must be less than 260 characters" } |
ForEach-Object { $_.TargetObject }

If you don't care about these files (may be applicable in some cases), simply drop the -ErrorVariable AccessDenied part.

Just a note which may be helpful- I was having this trouble with Apache on my laptop (which connects by wifi AFTER startup), and restarting the server (after connect) fixed the issue. I guess in my case this may be to do with apache starting offline and perhaps there noting that DNS lookups fail?

Your question as I understand it is divided in two parts, part one being you need a better understanding of the Naive Bayes classifier & part two being the confusion surrounding Training set.

In general all of Machine Learning Algorithms need to be trained for supervised learning tasks like classification, prediction etc. or for unsupervised learning tasks like clustering.

During the training step, the algorithms are taught with a particular input dataset (training set) so that later on we may test them for unknown inputs (which they have never seen before) for which they may classify or predict etc (in case of supervised learning) based on their learning. This is what most of the Machine Learning techniques like Neural Networks, SVM, Bayesian etc. are based upon.

So in a general Machine Learning project basically you have to divide your input set to a Development Set (Training Set + Dev-Test Set) & a Test Set (or Evaluation set). Remember your basic objective would be that your system learns and classifies new inputs which they have never seen before in either Dev set or test set.

The test set typically has the same format as the training set. However, it is very important that the test set be distinct from the training corpus: if we simply reused the training set as the test set, then a model that simply memorized its input, without learning how to generalize to new examples, would receive misleadingly high scores.

In general, for an example, 70% of our data can be used as training set cases. Also remember to partition the original set into the training and test sets randomly.

Now I come to your other question about Naive Bayes.

To demonstrate the concept of Naïve Bayes Classification, consider the example given below:

As indicated, the objects can be classified as either GREEN or RED. Our task is to classify new cases as they arrive, i.e., decide to which class label they belong, based on the currently existing objects.

Since there are twice as many GREEN objects as RED, it is reasonable to believe that a new case (which hasn't been observed yet) is twice as likely to have membership GREEN rather than RED. In the Bayesian analysis, this belief is known as the prior probability. Prior probabilities are based on previous experience, in this case the percentage of GREEN and RED objects, and often used to predict outcomes before they actually happen.

Thus, we can write:

Prior Probability of GREEN: number of GREEN objects / total number of objects

Prior Probability of RED: number of RED objects / total number of objects

Since there is a total of 60 objects, 40 of which are GREEN and 20 RED, our prior probabilities for class membership are:

Prior Probability for GREEN: 40 / 60

Prior Probability for RED: 20 / 60

Having formulated our prior probability, we are now ready to classify a new object (WHITE circle in the diagram below). Since the objects are well clustered, it is reasonable to assume that the more GREEN (or RED) objects in the vicinity of X, the more likely that the new cases belong to that particular color. To measure this likelihood, we draw a circle around X which encompasses a number (to be chosen a priori) of points irrespective of their class labels. Then we calculate the number of points in the circle belonging to each class label. From this we calculate the likelihood:

From the illustration above, it is clear that Likelihood of X given GREEN is smaller than Likelihood of X given RED, since the circle encompasses 1 GREEN object and 3 RED ones. Thus:

Although the prior probabilities indicate that X may belong to GREEN (given that there are twice as many GREEN compared to RED) the likelihood indicates otherwise; that the class membership of X is RED (given that there are more RED objects in the vicinity of X than GREEN). In the Bayesian analysis, the final classification is produced by combining both sources of information, i.e., the prior and the likelihood, to form a posterior probability using the so-called Bayes' rule (named after Rev. Thomas Bayes 1702-1761).

Finally, we classify X as RED since its class membership achieves the largest posterior probability.

How to break out in java??

Ans: Best way: System.exit(0);

Java language provides three jump statemnts that allow you to interrupt the normal flow of program.

These include break , continue ,return ,labelled break statement for e.g

import java.util.Scanner;
class demo
{   
    public static void main(String args[])
    {
            outerLoop://Label
            for(int i=1;i<=10;i++)
            {
                    for(int j=1;j<=i;j++)
                    {   
                        for(int k=1;k<=j;k++)
                        {
                            System.out.print(k+"\t");
                            break outerLoop;
                        }
                     System.out.println();                  
                    }
             System.out.println();
            }
    }   
}

Output: 1

Now Note below Program:

import java.util.Scanner;
class demo
{   
    public static void main(String args[])
    {
            for(int i=1;i<=10;i++)
            {
                    for(int j=1;j<=i;j++)
                    {   
                        for(int k=1;k<=j;k++)
                        {
                            System.out.print(k+"\t");
                            break ;
                        }                   
                    }
             System.out.println();
            }
    }   
}

output:

1
11
111
1111

and so on upto

1111111111

Similarly you can use continue statement just replace break with continue in above example.

downloaded Sql server management 2008 r2 and got it installed. Its getting installed but when I try to connect it via .\SQLEXPRESS it shows error. DO I need to install any SQL service on my system?

You installed management studio which is just a management interface to SQL Server. If you didn't (which is what it seems like) already have SQL Server installed, you'll need to install it in order to have it on your system and use it.

I got too much problem in installing php-mcrypt using epel-release-6-8.noarch.rpm. It has some dependency problem.

Then I tried in different way.

Get the php-mcrypt using "wget ftp://ftp.univie.ac.at/systems/linux/fedora/epel/6/x86_64/php-mcrypt-5.3.3-3.el6.x86_64.rpm" command.

Then install libmcrypt

ftp://ftp.pbone.net/mirror/download.fedora.redhat.com/pub/fedora/epel/6/x86_64/libmcrypt-2.5.8-9.el6.x86_64.rpm

The installed php-mcrypt using following command

yum install php-mcrypt-5.3.3-3.el6.x86_64.rpm

There is also a std::numbers::e of course :-) How to calculate Euler constant or Euler powered in C++?

These constants use the C++14 variable template feature: C++14 Variable Templates: what is their purpose? Any usage example?

In earlier versions of the draft, the constant was under std::math::pi: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p0631r7.pdf

Performance characteristics for lists are described on Effbot.

Python lists are actually implemented as vector for fast random access, so the container will basically hold as many items as there is space for in memory. (You need space for pointers contained in the list as well as space in memory for the object(s) being pointed to.)

Appending is O(1) (amortized constant complexity), however, inserting into/deleting from the middle of the sequence will require an O(n) (linear complexity) reordering, which will get slower as the number of elements in your list.

Your sorting question is more nuanced, since the comparison operation can take an unbounded amount of time. If you're performing really slow comparisons, it will take a long time, though it's no fault of Python's list data type.

Reversal just takes the amount of time it required to swap all the pointers in the list (necessarily O(n) (linear complexity), since you touch each pointer once).

This is like user3076252's answer, but you'll be choosing a different set of options:

• Project > Properties > Java Build Path
• Select Libraries tab > Alternate JRE > Installed JREs...
• Click "Search." Unless you know the exact folder name, you should choose a drive to search.

It should find your unbound JRE, but this time with all the numbers in it's name (rather than unbound), and you can select it. It will take a while to search the drive, but you can stop it at any time, and it will save the results, if any.

jQuery 3

As of jQuery 3, removeAttr does not set the corresponding property to false anymore:

Prior to jQuery 3.0, using .removeAttr() on a boolean attribute such as checked, selected, or readonly would also set the corresponding named property to false. This behavior was required for ancient versions of Internet Explorer but is not correct for modern browsers because the attribute represents the initial value and the property represents the current (dynamic) value.

It is almost always a mistake to use .removeAttr( "checked" ) on a DOM element. The only time it might be useful is if the DOM is later going to be serialized back to an HTML string. In all other cases, .prop( "checked", false ) should be used instead.

Changelog

Hence only .prop('checked',false) is correct way when using this version.

Original answer (from 2011):

For attributes which have underlying boolean properties (of which checked is one), removeAttr automatically sets the underlying property to false. (Note that this is among the backwards-compatibility "fixes" added in jQuery 1.6.1).

So, either will work... but the second example you gave (using prop) is the more correct of the two. If your goal is to uncheck the checkbox, you really do want to affect the property, not the attribute, and there's no need to go through removeAttr to do that.

You need to close the connection before you can use the output parameters. Something like this

con.Close();
MessageBox.Show(cmd.Parameters["@code"].Value.ToString());

Your concatenation syntax is correct.

Most likely the callback function isn't even being called. You can test that by putting an alert(), console.log() or debugger line in that function.

If it isn't being called, most likely there's an AJAX error. Look at chaining a .fail() handler after $.post() to find out what the error is, e.g.:

$.post('ajaxskeleton.php', {
    red: text       
}, function(){
    $('#part' + number).html(text);
}).fail(function(jqXHR, textStatus, errorThrown) {
    console.log(arguments);
});

We use SubClass extends SuperClass only when the subclass wants to use some functionality (methods or instance variables) that is already declared in the SuperClass, or if I want to slightly modify the functionality of the SuperClass (Method overriding). But say, I have an Animal class(SuperClass) and a Dog class (SubClass) and there are few methods that I have defined in the Animal class eg. doEat(); , doSleep(); ... and many more.

Now, my Dog class can simply extend the Animal class, if i want my dog to use any of the methods declared in the Animal class I can invoke those methods by simply creating a Dog object. So this way I can guarantee that I have a dog that can eat and sleep and do whatever else I want the dog to do.

Now, imagine, one day some Cat lover comes into our workspace and she tries to extend the Animal class(cats also eat and sleep). She makes a Cat object and starts invoking the methods.

But, say, someone tries to make an object of the Animal class. You can tell how a cat sleeps, you can tell how a dog eats, you can tell how an elephant drinks. But it does not make any sense in making an object of the Animal class. Because it is a template and we do not want any general way of eating.

So instead, I will prefer to make an abstract class that no one can instantiate but can be used as a template for other classes.

So to conclude, Interface is nothing but an abstract class(a pure abstract class) which contains no method implementations but only the definitions(the templates). So whoever implements the interface just knows that they have the templates of doEat(); and doSleep(); but they have to define their own doEat(); and doSleep(); methods according to their need.

You extend only when you want to reuse some part of the SuperClass(but keep in mind, you can always override the methods of your SuperClass according to your need) and you implement when you want the templates and you want to define them on your own(according to your need).

I will share with you a piece of code: You try it with different sets of inputs and look at the results.

class AnimalClass {

public void doEat() {
    
    System.out.println("Animal Eating...");
}

public void sleep() {
    
    System.out.println("Animal Sleeping...");
}

}

public class Dog extends AnimalClass implements AnimalInterface, Herbi{

public static void main(String[] args) {
    
    AnimalInterface a = new Dog();
    Dog obj = new Dog();
    obj.doEat();
    a.eating();
    
    obj.eating();
    obj.herbiEating();
}

public void doEat() {
    System.out.println("Dog eating...");
}

@Override
public void eating() {
    
    System.out.println("Eating through an interface...");
    // TODO Auto-generated method stub
    
}

@Override
public void herbiEating() {
    
    System.out.println("Herbi eating through an interface...");
    // TODO Auto-generated method stub
    
}


}

Defined Interfaces :

public interface AnimalInterface {

public void eating();

}


interface Herbi {

public void herbiEating();

}

Standard UITableViewCell already contains UIImageView that appears to the left to all your labels if its image is set. You can access it using imageView property:

cell.imageView.image = someImage;

If for some reason standard behavior does not suit your needs (note that you can customize properties of that standard image view) then you can add your own UIImageView to the cell as Aman suggested in his answer. But in that approach you'll have to manage cell's layout yourself (e.g. make sure that cell labels do not overlap image). And do not add subviews to the cell directly - add them to cell's contentView:

// DO NOT!
[cell addSubview:imv]; 
// DO:
[cell.contentView addSubview:imv];

The concern is we should not use ALLOW_ALL_HOSTNAME_VERIFIER.

How about I implement my own hostname verifier?

class MyHostnameVerifier implements org.apache.http.conn.ssl.X509HostnameVerifier
{
    @Override
    public boolean verify(String host, SSLSession session) {
        String sslHost = session.getPeerHost();
        System.out.println("Host=" + host);
        System.out.println("SSL Host=" + sslHost);    
        if (host.equals(sslHost)) {
            return true;
        } else {
            return false;
        }
    }

    @Override
    public void verify(String host, SSLSocket ssl) throws IOException {
        String sslHost = ssl.getInetAddress().getHostName();
        System.out.println("Host=" + host);
        System.out.println("SSL Host=" + sslHost);    
        if (host.equals(sslHost)) {
            return;
        } else {
            throw new IOException("hostname in certificate didn't match: " + host + " != " + sslHost);
        }
    }

    @Override
    public void verify(String host, X509Certificate cert) throws SSLException {
        throw new SSLException("Hostname verification 1 not implemented");
    }

    @Override
    public void verify(String host, String[] cns, String[] subjectAlts) throws SSLException {
        throw new SSLException("Hostname verification 2 not implemented");
    }
}

Let's test against https://www.rideforrainbows.org/ which is hosted on a shared server.

public static void main (String[] args) throws Exception {
    //org.apache.http.conn.ssl.SSLSocketFactory sf = org.apache.http.conn.ssl.SSLSocketFactory.getSocketFactory();
    //sf.setHostnameVerifier(new MyHostnameVerifier());
    //org.apache.http.conn.scheme.Scheme sch = new Scheme("https", 443, sf);

    org.apache.http.client.HttpClient client = new DefaultHttpClient();
    //client.getConnectionManager().getSchemeRegistry().register(sch);
    org.apache.http.client.methods.HttpPost post = new HttpPost("https://www.rideforrainbows.org/");
    org.apache.http.HttpResponse response = client.execute(post);
    java.io.InputStream is = response.getEntity().getContent();
    java.io.BufferedReader rd = new java.io.BufferedReader(new java.io.InputStreamReader(is));
    String line;
    while ((line = rd.readLine()) != null) { 
        System.out.println(line);
    }
}

SSLException:

Exception in thread "main" javax.net.ssl.SSLException: hostname in certificate didn't match: www.rideforrainbows.org != stac.rt.sg OR stac.rt.sg OR www.stac.rt.sg
at org.apache.http.conn.ssl.AbstractVerifier.verify(AbstractVerifier.java:231)
...

Do with MyHostnameVerifier:

public static void main (String[] args) throws Exception {
    org.apache.http.conn.ssl.SSLSocketFactory sf = org.apache.http.conn.ssl.SSLSocketFactory.getSocketFactory();
    sf.setHostnameVerifier(new MyHostnameVerifier());
    org.apache.http.conn.scheme.Scheme sch = new Scheme("https", 443, sf);

    org.apache.http.client.HttpClient client = new DefaultHttpClient();
    client.getConnectionManager().getSchemeRegistry().register(sch);
    org.apache.http.client.methods.HttpPost post = new HttpPost("https://www.rideforrainbows.org/");
    org.apache.http.HttpResponse response = client.execute(post);
    java.io.InputStream is = response.getEntity().getContent();
    java.io.BufferedReader rd = new java.io.BufferedReader(new java.io.InputStreamReader(is));
    String line;
    while ((line = rd.readLine()) != null) { 
        System.out.println(line);
    }
}

Shows:

Host=www.rideforrainbows.org
SSL Host=www.rideforrainbows.org

At least I have the logic to compare (Host == SSL Host) and return true.

The above source code is working for httpclient-4.2.3.jar and httpclient-4.3.3.jar.

Try this:

Dim strFile As String = "yourfile.txt"
Dim fileExists As Boolean = File.Exists(strFile)
Using sw As New StreamWriter(File.Open(strFile, FileMode.OpenOrCreate))
    sw.WriteLine( _
        IIf(fileExists, _
            "Error Message in  Occured at-- " & DateTime.Now, _
            "Start Error Log for today"))
End Using

String[] tblHead={"Item Name","Price","Qty","Discount"};
DefaultTableModel dtm=new DefaultTableModel(tblHead,0);
JTable tbl=new JTable(dtm);
String[] item={"A","B","C","D"};
dtm.addRow(item);

Here;this is the solution.

Unless you are already using CollectionUtils I would go for List.isEmpty(), less dependencies.

Performance wise CollectionUtils will be a tad slower. Because it basically follows the same logic but has additional overhead.

So it would be readability vs. performance vs. dependencies. Not much of a big difference though.

The user-agent should be specified as a field in the header.

Here is a list of HTTP header fields, and you'd probably be interested in request-specific fields, which includes User-Agent.

If you're using requests v2.13 and newer

The simplest way to do what you want is to create a dictionary and specify your headers directly, like so:

import requests

url = 'SOME URL'

headers = {
    'User-Agent': 'My User Agent 1.0',
    'From': '[email protected]'  # This is another valid field
}

response = requests.get(url, headers=headers)

If you're using requests v2.12.x and older

Older versions of requests clobbered default headers, so you'd want to do the following to preserve default headers and then add your own to them.

import requests

url = 'SOME URL'

# Get a copy of the default headers that requests would use
headers = requests.utils.default_headers()

# Update the headers with your custom ones
# You don't have to worry about case-sensitivity with
# the dictionary keys, because default_headers uses a custom
# CaseInsensitiveDict implementation within requests' source code.
headers.update(
    {
        'User-Agent': 'My User Agent 1.0',
    }
)

response = requests.get(url, headers=headers)

Looks like the extension is not installed in the particular database you require it.

You should connect to this particular database with

 \CONNECT my_database

Then install the extension in this database

 CREATE EXTENSION "uuid-ossp";

When you call a function, a new "namespace" is allocated on the stack. That's how functions can have local variables. As functions call functions, which in turn call functions, we keep allocating more and more space on the stack to maintain this deep hierarchy of namespaces.

To curb programs using massive amounts of stack space, a limit is usually put in place via ulimit -s. If we remove that limit via ulimit -s unlimited, our programs will be able to keep gobbling up RAM for their evergrowing stack until eventually the system runs out of memory entirely.

int eat_stack_space(void) { return eat_stack_space(); }
// If we compile this with no optimization and run it, our computer could crash.

Usually, using a ton of stack space is accidental or a symptom of very deep recursion that probably should not be relying so much on the stack. Thus the stack limit.

Impact on performace is minor but does exist. Using the time command, I found that eliminating the stack limit increased performance by a few fractions of a second (at least on 64bit Ubuntu).

If you're trying to get the string into a variable, another easy way is something like this:

USAGE=$(cat <<-END
    This is line one.
    This is line two.
    This is line three.
END
)

If you indent your string with tabs (i.e., '\t'), the indentation will be stripped out. If you indent with spaces, the indentation will be left in.

NOTE: It is significant that the last closing parenthesis is on another line. The END text must appear on a line by itself.

I use this simple, clean and effective method.

I place arguments in an array, 1 per line. This way it is very easy to read and edit. Then I use a simple trick of passing all arguments inside double quotes to a function with 1 single parameter. That flattens them, including arrays, to a single string, which I then execute using PS's 'Invoke-Expression'. This directive is specifically designed to convert a string to runnable command. Works well:

# function with one argument will flatten 
# all passed-in entries into 1 single string line
Function Execute($command) {
    # execute:
    Invoke-Expression $command;
    # if you have trouble try:
    # Invoke-Expression "& $command";
    # or if you need also output to a variable
    # Invoke-Expression $command | Tee-Object -Variable cmdOutput;
}

#  ... your main code here ...

# The name of your executable app
$app = 'my_app.exe';
# List of arguments:
# Notice the type of quotes - important !
# Those in single quotes are normal strings, like 'Peter'
$args = 'arg1',
        'arg2',
        $some_variable,
        'arg4',
        "arg5='with quotes'",
        'arg6',
        "arg7 \ with \ $other_variable",
        'etc...';
    
# pass all arguments inside double quotes
Execute "$app $args";

What you need is overflow-y: scroll;

    textarea {_x000D_
        overflow-y: scroll;_x000D_
        height: 100px;_x000D_

    }

<textarea></textarea>

The default specifier depends upon context.

For classes, and interface declarations, the default is package private. This falls between protected and private, allowing only classes in the same package access. (protected is like this, but also allowing access to subclasses outside of the package.)

class MyClass   // package private
{
   int field;    // package private field

   void calc() {  // package private method

   }
}

For interface members (fields and methods), the default access is public. But note that the interface declaration itself defaults to package private.

interface MyInterface  // package private
{
   int field1;         // static final public

   void method1();     // public abstract
}

If we then have the declaration

public interface MyInterface2 extends MyInterface
{

}

Classes using MyInterface2 can then see field1 and method1 from the super interface, because they are public, even though they cannot see the declaration of MyInterface itself.

As a general rule, you can use Database_Default collation so you don't need to figure out which one to use. However, I strongly suggest reading Simons Liew's excellent article Understanding the COLLATE DATABASE_DEFAULT clause in SQL Server

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p
  ON (p.vTreasuryId = f.RFC) COLLATE Database_Default 

JSON.stringify returns a String. So, for example:

var data = [
    { id: 1, name: "bob" },
    { id: 2, name: "john" },
    { id: 3, name: "jake" },
];

JSON.stringify(data)

will return the equivalent of:

"[{\"id\":1,\"name\":\"bob\"},{\"id\":2,\"name\":\"john\"},{\"id\":3,\"name\":\"jake\"}]"

as a String value.

So when you have

<% for(var i=0; i<JSON.stringify(data).length; i++) {%>

what that ends up looking like is:

<% for(var i=0; i<"[{\"id\":1,\"name\":\"bob\"},{\"id\":2,\"name\":\"john\"},{\"id\":3,\"name\":\"jake\"}]".length; i++) {%>

which is probably not what you want. What you probably do want is something like this:

<table>
<% for(var i=0; i < data.length; i++) { %>
   <tr>
     <td><%= data[i].id %></td>
     <td><%= data[i].name %></td>
   </tr>
<% } %>
</table>

This will output the following table (using the example data from above):

<table>
  <tr>
    <td>1</td>
    <td>bob</td>
  </tr>
  <tr>
    <td>2</td>
    <td>john</td>
  </tr>
  <tr>
    <td>3</td>
    <td>jake</td>
  </tr>
</table>

You can use LINQ to XML,

XDocument doc = XDocument.Load(file);

var result = (from ele in doc.Descendants("section")
              select ele).ToList();

foreach (var t in result)
{
    if (t.Attributes("split").Count() != 0)
    {
        // Exist
    }

    // Suggestion from @UrbanEsc
    if(t.Attributes("split").Any())
    {

    }
}

OR

 XDocument doc = XDocument.Load(file);

 var result = (from ele in doc.Descendants("section").Attributes("split")
               select ele).ToList();

 foreach (var t in result)
 {
     // Response.Write("<br/>" +  t.Value);
 }

This is the simplest way to plot an ROC curve, given a set of ground truth labels and predicted probabilities. Best part is, it plots the ROC curve for ALL classes, so you get multiple neat-looking curves as well

import scikitplot as skplt
import matplotlib.pyplot as plt

y_true = # ground truth labels
y_probas = # predicted probabilities generated by sklearn classifier
skplt.metrics.plot_roc_curve(y_true, y_probas)
plt.show()

Here's a sample curve generated by plot_roc_curve. I used the sample digits dataset from scikit-learn so there are 10 classes. Notice that one ROC curve is plotted for each class.

Disclaimer: Note that this uses the scikit-plot library, which I built.

On thing to remember here is that the default param must be the last param in the function definition.

Following code will not compile:

void fun(int first, int second = 10, int third);

Following code will compile:

void fun(int first, int second, int third = 10);

void foo() {
  /* do some stuff */
  if (!condition) {
    return;
  }
}

You can just use the return keyword just like you would in any other function.

I took a long look at many questions like this, and found this post... I didn't like the fact that the conversion code is duplicated for each type, so I've made a generic method to perform the task:

public static byte[] toByteArray(long value, int n)

That what manual says about setOnClickListener method is:

public void setOnClickListener (View.OnClickListener l)

Added in API level 1 Register a callback to be invoked when this view is clicked. If this view is not clickable, it becomes clickable.

Parameters

l View.OnClickListener: The callback that will run

And normally you have to use it like this

public class ExampleActivity extends Activity implements OnClickListener {
    protected void onCreate(Bundle savedValues) {
        ...
        Button button = (Button)findViewById(R.id.corky);
        button.setOnClickListener(this);
    }

    // Implement the OnClickListener callback
    public void onClick(View v) {
      // do something when the button is clicked
    }
    ...
}

Take a look at this lesson as well Building a Simple Calculator using Android Studio.

#include <iostream>

using namespace std;

int main() {
  // There used to be
  // int left, right;
  // But not anymore

  if (left != right)
    std::cout << "Excuse me, WHAT?!\n";
}

So, why? Because it brings in identifiers that overlap commonly used variable names, and lets this code compile, interpreting it to mean if (std::left != std::right).

PVS-Studio can find such an error using the V1058 diagnostic: https://godbolt.org/z/YZTwhp (thank you Andrey Karpov!!).

Pinging cppcheck developers: you might wish to flag this one. It was a doozy.

I would do something like this:

Select count(*), productid
from products
where keyword = '$keyword'
group by productid

that will give you a list like

count(*)    productid  
----------------------
 5           12345   
 3           93884   
 9           93493    

This allows you to see how many of each distinct productid ID is associated with the keyword.

For general reference. There is a simpler way using the library Supercharged. Although, you can use extension methods with all solutions mentioned, you find practical user library toolkit.

"#ff00ff".toColor(); // painless hex to color
"red".toColor(); // supports all web color names

Easier, right?

Supercharged

As mentioned in the question, there is the clip css property, although it does require that the element being clipped is position: absolute; (which is a shame):

.container {_x000D_
  position: relative;_x000D_
}_x000D_
#clip {_x000D_
  position: absolute;_x000D_
  clip: rect(0, 100px, 200px, 0);_x000D_
  /* clip: shape(top, right, bottom, left); NB 'rect' is the only available option */_x000D_
}

<div class="container">_x000D_
  <img src="http://lorempixel.com/200/200/nightlife/3" />_x000D_

</div>

To supplement the original answer – somewhat belatedly – I'm editing to show the use of clip-path, which has replaced the now-deprecated clip property.

The clip-path property allows a range of options (more-so than the original clip), of:

• inset — rectangular/cuboid shapes, defined with four values as 'distance-from' (top right bottom left).
• circle — circle(diameter at x-coordinate y-coordinate).
• ellipse — ellipse(x-axis-length y-axis-length at x-coordinate y-coordinate).
• polygon — defined by a series of x/y coordinates in relation to the element's origin of the top-left corner. As the path is closed automatically the realistic minimum number of points for a polygon should be three, any fewer (two) is a line or (one) is a point: polygon(x-coordinate1 y-coordinate1, x-coordinate2 y-coordinate2, x-coordinate3 y-coordinate3, [etc...]).
• url — this can be either a local URL (using a CSS id-selector) or the URL of an external file (using a file-path) to identify an SVG, though I've not experimented with either (as yet), so I can offer no insight as to their benefit or caveat.

Actually, a Swing component does have multiple dimensions, as:

• current size - setSize() and setBounds() sets this
• minimum size - setMinimumSize() sets this
• preferred size - setPerferredSize() sets this
• maximum size - setMaximumSize() sets this.

SetBounds is a shortcut for setting current size plus location of the widget if you don't use any layout manager.

If you use a layout manager, it is the responsibility of the layout manager to lay out your components, taking into account the preferred size you set, and ensuring that the comonent never gets smaller than its minimumSize or bigger than its maximumSize.

In this case, the layoutManager will call setSize (or setBounds), and you can not really control the position or dimension of the component.

The whole point of using a layout manager is to have a platform and window-size independent way of laying out your components automatically, therefore you don't expect to call setSize from your code.

(Personal comment: There are buggy layout managers, I personally hate all of them and rolled my own, which offers the flexibility of MigLayout without the learning curve.)

// you need to have a list of data that you want the spinner to display
List<String> spinnerArray =  new ArrayList<String>();
spinnerArray.add("item1");
spinnerArray.add("item2");

ArrayAdapter<String> adapter = new ArrayAdapter<String>(
    this, android.R.layout.simple_spinner_item, spinnerArray);

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner sItems = (Spinner) findViewById(R.id.spinner1);
sItems.setAdapter(adapter);

also to find out what is selected you could do something like this

String selected = sItems.getSelectedItem().toString();
if (selected.equals("what ever the option was")) {
}

After several months, the best answer I have is my simple tool. It is raw but functional.

What I want is something similar to this. The JSON data can provide a skeleton for the JSON schema. I have not implemented it yet, but it should be possible to give an existing JSON schema as basis, so that the existing JSON schema plus JSON data can generate an updated JSON schema. If no such schema is given as input, completely default values are taken.

This would be very useful in iterative development: the first time the tool is run, the JSON schema is dummy, but it can be refined automatically according to the evolution of the data.

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

Somewhere you have to keep track of what button had been pressed. When things happen, you need to store something in a variable so you can recall the information or it's gone forever.

When someone pressed one of the operator buttons, don't just let them type in another value. Save the operator symbol, then let them type in another value. You could literally just have a String operator that gets the text of the operator button pressed. Then, when the equals button is pressed, you have to check to see which operator you stored. You could do this with an if/else if/else chain.

So, in your symbol's button press event, store the symbol text in a variable, then, in the = button press event, check to see which symbol is in the variable and act accordingly.

Alternatively, if you feel comfortable enough with enums (looks like you're just starting, so if you're not to that point yet, ignore this), you could have an enumeration of symbols that lets you check symbols easily with a switch.

The accepted answer gave two locations:

here

C:\Documents and Settings\Administrator\Local Settings\Temp\VWDWebCache

and possibly here

C:\Documents and Settings\Administrator\Local Settings\Application Data\Microsoft\WebsiteCache

Did you try those?

Edited to add

On my Windows Vista machine, it's located in

%Temp%\VWDWebCache

and in

%LocalAppData%\Microsoft\WebsiteCache

From your additional information (regarding team edition) this comes from Clear Client TFS Cache:

Clear Client TFS Cache

Visual Studio and Team Explorer provide a caching mechanism which can get out of sync. If I have multiple instances of a single TFS which can be connected to from a single Visual Studio client, that client can become confused.

To solve it..

For Windows Vista delete contents of this folder

%LocalAppData%\Microsoft\Team Foundation\1.0\Cache

Such a thing probably does not exist "as-is". It doesn't really exist on Linux or other UNIX-like operating systems either though.

ncurses is only a library that helps you manage interactions with the underlying terminal environment. But it doesn't provide a terminal emulator itself.

The thing that actually displays stuff on the screen (which in your requirement is listed as "native resizable win32 windows") is usually called a Terminal Emulator. If you don't like the one that comes with Windows (you aren't alone; no person on Earth does) there are a few alternatives. There is Console, which in my experience works sometimes and appears to just wrap an underlying Windows terminal emulator (I don't know for sure, but I'm guessing, since there is a menu option to actually get access to that underlying terminal emulator, and sure enough an old crusty Windows/DOS box appears which mirrors everything in the Console window).

A better option

Another option, which may be more appealing is puttycyg. It hooks in to Putty (which, coming from a Linux background, is pretty close to what I'm used to, and free) but actually accesses an underlying cygwin instead of the Windows command interpreter (CMD.EXE). So you get all the benefits of Putty's awesome terminal emulator, as well as nice ncurses (and many other) libraries provided by cygwin. Add a couple command line arguments to the Shortcut that launches Putty (or the Batch file) and your app can be automatically launched without going through Putty's UI.

I believe the example you've posted is using HTML5, which allows you to jump to any DOM element with the matching ID attribute. To support older browsers, you'll need to change:

<div id="timeline" name="timeline" ...>

To the old format:

<a name="timeline" />

You'll then be able to navigate to /academics/page.html#timeline and jump right to that section.

Also, check out this similar question.

You may try this one,

declare @Number INT = 5                            
print 'There are ' + CONVERT(VARCHAR, @Number) + ' alias combinations did not match a record'

For me, I had ~6 different Nuget packages to update and when I selected Microsoft.AspNetCore.All first, I got the referenced error.

I started at the bottom and updated others first (EF Core, EF Design Tools, etc), then when the only one that was left was Microsoft.AspNetCore.All it worked fine.

Sorry, but Eduardos solution did not work for me. At the end, I realized that disabled datepicker is just a read-only textbox. So you should make it read only and destroy the datepicker. Field will be sent to server upon submit.

Here is a bit generalized code that takes multiple textboxes and makes them read only. It will strip off the datepickers as well.

fields.attr("readonly", "readonly");
fields.each(function(idx, fld) {
    if($(fld).hasClass('hasDatepicker'))
    {
        $(fld).datepicker("destroy");
    }
});

You can use list ?? Enumerable.Empty<Friend>(), or have FindFriends return Enumerable.Empty<Friend>()

In most software that generates RSA private keys, including openssl's, the private key is represented as a PKCS#1 RSAPrivatekey object or some variant thereof:

A.1.2 RSA private key syntax

An RSA private key should be represented with the ASN.1 type
RSAPrivateKey:

  RSAPrivateKey ::= SEQUENCE {
      version           Version,
      modulus           INTEGER,  -- n
      publicExponent    INTEGER,  -- e
      privateExponent   INTEGER,  -- d
      prime1            INTEGER,  -- p
      prime2            INTEGER,  -- q
      exponent1         INTEGER,  -- d mod (p-1)
      exponent2         INTEGER,  -- d mod (q-1)
      coefficient       INTEGER,  -- (inverse of q) mod p
      otherPrimeInfos   OtherPrimeInfos OPTIONAL
  }

As you can see, this format has a number of fields including the modulus and public exponent and thus is a strict superset of the information in an RSA public key.

This is what you need :)

$('._someDropDown').live('change', function(e) {
    console.log(e.target.options[e.target.selectedIndex].text);
});

For new jQuery use on

$(document).on('change', '._someDropDown', function(e) {
    console.log(this.options[e.target.selectedIndex].text);
});

Here is a script (works for an arbitrary number of specified files (not just all in the working directory), without additional files, also works for .mov; tested on macOS):

#!/bin/bash

    echo "Usage: `basename $0` input_1.mp4 input_2.mp4 ... output.mp4"
    exit 0
fi

ARGS=("$@") # determine all arguments
output=${ARGS[${#ARGS[@]}-1]} # get the last argument (output file)
unset ARGS[${#ARGS[@]}-1] # drop it from the array
(for f in "${ARGS[@]}"; do echo "file '$f'"; done) | ffmpeg -protocol_whitelist file,pipe -f concat -safe 0 -i pipe: -vcodec copy -acodec copy $output

It's OK, I got it! Thanks for your help!

Here is the code to do it:

private void button1_Click(object sender, EventArgs e)
{
    selectedServer = "JS000943";
    listBox1.Items.Add(GetProcessorIdleTime(selectedServer).ToString());
}

private static int GetProcessorIdleTime(string selectedServer)
{
    try
    {
        var searcher = new
           ManagementObjectSearcher
             (@"\\"+ selectedServer +@"\root\CIMV2",
              "SELECT * FROM Win32_PerfFormattedData_PerfOS_Processor WHERE Name=\"_Total\"");

        ManagementObjectCollection collection = searcher.Get();
        ManagementObject queryObj = collection.Cast<ManagementObject>().First();

        return Convert.ToInt32(queryObj["PercentIdleTime"]);
    }
    catch (ManagementException e)
    {
        MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
    }
    return -1;
}

tl;dr: You don't have to remove the slashes, you have nested JSON, and hence have to decode the JSON twice: DEMO (note I used double slashes in the example, because the JSON is inside a JS string literal).

I assume that your actual JSON looks like

{"data":"{\n \"taskNames\" : [\n \"01 Jan\",\n \"02 Jan\",\n \"03 Jan\",\n \"04 Jan\",\n \"05 Jan\",\n \"06 Jan\",\n \"07 Jan\",\n \"08 Jan\",\n \"09 Jan\",\n \"10 Jan\",\n \"11 Jan\",\n \"12 Jan\",\n \"13 Jan\",\n \"14 Jan\",\n \"15 Jan\",\n \"16 Jan\",\n \"17 Jan\",\n \"18 Jan\",\n \"19 Jan\",\n \"20 Jan\",\n \"21 Jan\",\n \"22 Jan\",\n \"23 Jan\",\n \"24 Jan\",\n \"25 Jan\",\n \"26 Jan\",\n \"27 Jan\"]}"}

I.e. you have a top level object with one key, data. The value of that key is a string containing JSON itself. This is usually because the server side code didn't properly create the JSON. That's why you see the \" inside the string. This lets the parser know that " is to be treated literally and doesn't terminate the string.

So you can either fix the server side code, so that you don't double encode the data, or you have to decode the JSON twice, e.g.

var data = JSON.parse(JSON.parse(json).data));

To add to Mike Flynn's answer, since upgrading to Xcode 7 and running my app on an iOS 9 device, I added this to my (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

// Hide any window that isn't the main window
NSArray *windows = [[UIApplication sharedApplication] windows];
for (UIWindow *window in windows) {
    if (window != self.window) {
        window.hidden = YES;
    }
}

__func__ is an implicitly declared identifier that expands to a character array variable containing the function name when it is used inside of a function. It was added to C in C99. From C99 §6.4.2.2/1:

The identifier __func__ is implicitly declared by the translator as if, immediately following the opening brace of each function definition, the declaration

static const char __func__[] = "function-name";

appeared, where function-name is the name of the lexically-enclosing function. This name is the unadorned name of the function.

Note that it is not a macro and it has no special meaning during preprocessing.

__func__ was added to C++ in C++11, where it is specified as containing "an implementation-de?ned string" (C++11 §8.4.1[dcl.fct.def.general]/8), which is not quite as useful as the specification in C. (The original proposal to add __func__ to C++ was N1642).

__FUNCTION__ is a pre-standard extension that some C compilers support (including gcc and Visual C++); in general, you should use __func__ where it is supported and only use __FUNCTION__ if you are using a compiler that does not support it (for example, Visual C++, which does not support C99 and does not yet support all of C++0x, does not provide __func__).

__PRETTY_FUNCTION__ is a gcc extension that is mostly the same as __FUNCTION__, except that for C++ functions it contains the "pretty" name of the function including the signature of the function. Visual C++ has a similar (but not quite identical) extension, __FUNCSIG__.

For the nonstandard macros, you will want to consult your compiler's documentation. The Visual C++ extensions are included in the MSDN documentation of the C++ compiler's "Predefined Macros". The gcc documentation extensions are described in the gcc documentation page "Function Names as Strings."

How about

XmlSerializer xs = new XmlSerializer(typeof(user[]));
using (Stream ins = File.Open(@"c:\some.xml", FileMode.Open))
foreach (user o in (user[])xs.Deserialize(ins))
   userList.Add(o);    

Not particularly fancy but it should work.

Building up on @wasinger's reply above, in Bootstrap 4.5 I had to override not only the color variables but also the box-shadow itself.

$input-focus-width: .2rem !default;
$input-focus-color: rgba($YOUR_COLOR, .25) !default;
$input-focus-border-color: rgba($YOUR_COLOR, .5) !default;
$input-focus-box-shadow: 0 0 0 $input-focus-width $input-focus-color !default;

I had a similar problem. I got an exception "Type is not resolved for member 'Microsoft.IdentityModel.Claims.ClaimsPrincipal, Microsoft.IdentityModel, Version = 3.5.0.0, Culture = neutral, PublicKeyToken = 31bf3856ad364e35'.".

I tried to run the ASP.NET application from Visual Studio, which was a reference to a local copy of Microsoft.IdentityModel.dll.

I did not want to install the SDK and I had to copy the library to the directory "C: \ Program Files \ Common Files \ Microsoft Shared \ DevServer \ 10.0" and restart Visual Studio.

alternatively you can perform a fast export without using Office dll, as Excel can parse csv files without problems.

Doing something like this (for less than 65.536 rows with titles):

                Exit Sub
            End If

            Cursor.Current = Cursors.WaitCursor

            Dim sText As New System.Text.StringBuilder
            Dim sTmp As String
            Dim aVisibleData As New List(Of String)

            For iAuxRow As Integer = 0 To p_oGrid.Columns.Count - 1
                If p_oGrid.Columns(iAuxRow).Visible Then
                    aVisibleData.Add(p_oGrid.Columns(iAuxRow).Name)
                    sText.Append(p_oGrid.Columns(iAuxRow).HeaderText.ToUpper)
                    sText.Append(";")
                End If
            Next
            sText.AppendLine()

            For iAuxRow As Integer = 0 To p_oGrid.RowCount - 1
                Dim oRow As DataGridViewRow = p_oGrid.Rows(iAuxRow)
                For Each sCol As String In aVisibleData
                    Dim sVal As String
                    sVal = oRow.Cells(sCol).Value.ToString()
                    sText.Append(sVal.Replace(";", ",").Replace(vbCrLf, " ; "))
                    sText.Append(";")
                Next
                sText.AppendLine()

For the case that you wish to revert a recently installed package that made several changes to dependencies (such as tensorflow), you can "roll back" to an earlier installation state via the following method:

conda list --revisions
conda install --revision [revision number]

The first command shows previous installation revisions (with dependencies) and the second reverts to whichever revision number you specify.

Note that if you wish to (re)install a later revision, you may have to sequentially reinstall all intermediate versions. If you had been at revision 23, reinstalled revision 20 and wish to return, you may have to run each:

conda install --revision 21
conda install --revision 22
conda install --revision 23

You can do this:

$('.searchbychar').click(function () {
    var divID = '#' + this.id;
    $('html, body').animate({
        scrollTop: $(divID).offset().top
    }, 2000);
});

F.Y.I.

• You need to prefix a class name with a . (dot) like in your first line of code.
• $( 'searchbychar' ).click(function() {
• Also, your code $('.searchbychar').attr('id') will return a string ID not a jQuery object. Hence, you can not apply .offset() method to it.

I just learnt this myself the other day: the this keyword defines that method has being an extension of the class that proceeds it. So for your example, MyClass will have a new extension method called Foo (which doesn't accept any parameter and returns an int; it can be used as with any other public method).

First Find PID # - where the Rails Server got stuck on

Run this to find the stuck PID

cat ./tmp/pids/server.pid

It will return something like 65829

Then KILL that PID => kill 65829

Remove column constraint: not null to null

ALTER TABLE test ALTER COLUMN column_01 DROP NOT NULL;

An elegant way to move your file to an nonexistent directory is to create the following extension to native FileInfo class:

public static class FileInfoExtension
{
    //second parameter is need to avoid collision with native MoveTo
    public static void MoveTo(this FileInfo file, string destination, bool autoCreateDirectory) { 

        if (autoCreateDirectory)
        {
            var destinationDirectory = new DirectoryInfo(Path.GetDirectoryName(destination));

            if (!destinationDirectory.Exists)
                destinationDirectory.Create();
        }

        file.MoveTo(destination);
    }
}

Then use brand new MoveTo extension:

 using <namespace of FileInfoExtension>;
 ...
 new FileInfo("some path")
     .MoveTo("target path",true);

Check Methods extension documentation.

The WebRequest is an abstract base class. So you actually don't use it directly. You use it through it derived classes - HttpWebRequest and FileWebRequest.

You use Create method of WebRequest to create an instance of WebRequest. GetResponseStream returns data stream.

There are also FileWebRequest and FtpWebRequest classes that inherit from WebRequest. Normally, you would use WebRequest to, well, make a request and convert the return to either HttpWebRequest, FileWebRequest or FtpWebRequest, depend on your request. Below is an example:

Example:

var _request = (HttpWebRequest)WebRequest.Create("http://stackverflow.com");
var _response = (HttpWebResponse)_request.GetResponse();

WebClient

System.Object
        System.MarshalByRefObject
            System.ComponentModel.Component
                System.Net.WebClient

WebClient provides common operations to sending and receiving data from a resource identified by a URI. Simply, it’s a higher-level abstraction of HttpWebRequest. This ‘common operations’ is what differentiate WebClient from HttpWebRequest, as also shown in the sample below:

Example:

var _client = new WebClient();
var _stackContent = _client.DownloadString("http://stackverflow.com");

There are also DownloadData and DownloadFile operations under WebClient instance. These common operations also simplify code of what we would normally do with HttpWebRequest. Using HttpWebRequest, we have to get the response of our request, instantiate StreamReader to read the response and finally, convert the result to whatever type we expect. With WebClient, we just simply call DownloadData, DownloadFile or DownloadString.

However, keep in mind that WebClient.DownloadString doesn’t consider the encoding of the resource you requesting. So, you would probably end up receiving weird characters if you don’t specify and encoding.

NOTE: Basically "WebClient takes few lines of code as compared to Webrequest"

@@IDENTITY is the last identity inserted using the current SQL Connection. This is a good value to return from an insert stored procedure, where you just need the identity inserted for your new record, and don't care if more rows were added afterward.

SCOPE_IDENTITY is the last identity inserted using the current SQL Connection, and in the current scope -- that is, if there was a second IDENTITY inserted based on a trigger after your insert, it would not be reflected in SCOPE_IDENTITY, only the insert you performed. Frankly, I have never had a reason to use this.

IDENT_CURRENT(tablename) is the last identity inserted regardless of connection or scope. You could use this if you want to get the current IDENTITY value for a table that you have not inserted a record into.

Note that $(element).offset() tells you the position of an element relative to the document. This works great in most circumstances, but in the case of position:fixed you can get unexpected results.

If your document is longer than the viewport and you have scrolled vertically toward the bottom of the document, then your position:fixed element's offset() value will be greater than the expected value by the amount you have scrolled.

If you are looking for a value relative to the viewport (window), rather than the document on a position:fixed element, you can subtract the document's scrollTop() value from the fixed element's offset().top value. Example: $("#el").offset().top - $(document).scrollTop()

If the position:fixed element's offset parent is the document, you want to read parseInt($.css('top')) instead.

BernardSaucier has already given you an answer. My post is not an answer but an explanation as to why you shouldn't be using UsedRange.

UsedRange is highly unreliable as shown HERE

To find the last column which has data, use .Find and then subtract from it.

With Sheets("Sheet1")
    If Application.WorksheetFunction.CountA(.Cells) <> 0 Then
        lastCol = .Cells.Find(What:="*", _
                      After:=.Range("A1"), _
                      Lookat:=xlPart, _
                      LookIn:=xlFormulas, _
                      SearchOrder:=xlByColumns, _
                      SearchDirection:=xlPrevious, _
                      MatchCase:=False).Column
    Else
        lastCol = 1
    End If
End With

If lastCol > 8 Then
    'Debug.Print ActiveSheet.UsedRange.Columns.Count - 8

    'The above becomes

    Debug.Print lastCol - 8
End If

No requires converting the Task to int. Simply Use The Task Result.

int taskResult = AccessTheWebAndDouble().Result;

public async Task<int> AccessTheWebAndDouble()
{
    int task = AccessTheWeb();
    return task;
}

It will return the value if available otherwise it return 0.

Pretty strange, it should work out of the box as the ".modal-backdrop" class is defined top-level in the css.

<div class="modal-backdrop"></div>

Made a small demo: http://jsfiddle.net/PfBnq/

Look at this tutorial or this one, they are both pretty simple. If you are interested in an alternative this is how you do file I/O in C.

Some things to keep in mind, use single quotes ' when dealing with single characters, and double " for strings. Also it is a bad habit to use global variables when not necessary.

Have fun!

As seen on reddit:

$address = urlencode('1600 Pennsylvania Avenue, Washington, DC');
$json = json_decode(file_get_contents("http://where.yahooapis.com/geocode?q=$address&flags=J"));
print_r($json);

Only add this code into jQuery on document ready

Ref : http://css-tricks.com/snippets/jquery/smooth-scrolling/

$(function() {
  $('a[href*=#]:not([href=#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top
        }, 1000);
        return false;
      }
    }
  });
});

Workaround....

In VS 2015 Professional (and probably other versions). Go to Tools / Options / Environment / Fonts and Colours. In the "Show Settings For" drop-down, select "CodeLens" Choose the smallest font you can find e.g. Calibri 6. Change the foreground colour to your editor foreground colour (say "White") Click OK.

You can do something like this :

<asp:Button ID="Button1" runat="server" Text="Button"
    onclick="Button1_Click" OnClientClick="document.forms[0].target = '_blank';" />

You can use plenty of things.

• If you're a standards junkie, you can use the HTML5 <audio> tag:

Here is the official W3C specification for the audio tag.

Usage:

<audio controls>
 <source src="http://media.w3.org/2010/07/bunny/04-Death_Becomes_Fur.mp4"
         type='audio/mp4'>
 <!-- The next two lines are only executed if the browser doesn't support MP4 files -->
 <source src="http://media.w3.org/2010/07/bunny/04-Death_Becomes_Fur.oga"
         type='audio/ogg; codecs=vorbis'>
 <!-- The next line will only be executed if the browser doesn't support the <audio> tag-->
 <p>Your user agent does not support the HTML5 Audio element.</p>
</audio>

jsFiddle here.

• Or, if you want to support older browsers, you can use many of the free audio flash players available. Such as:

  • Dewplayer
  • MP3 Player (boring name... right? :) )
  • Website Music Player (even more boring... right?)
  • Zanorg Player

Note: I'm not sure which are the best ones, as I have never used one (yet).

UPDATE: As mentioned in another answer's comment, you are using XHTML 1.0 Transitional. You might be able to get <audio> to work with some hack.

UPDATE 2: I just remembered another way to do play audio. This will work in XHTML!!! This is fully standards-compliant.

You use this JavaScript:

var aud = document.createElement("iframe");
aud.setAttribute('src', "http://yoursite.com/youraudio.mp4"); // replace with actual file path
aud.setAttribute('width', '1px');
aud.setAttribute('height', '1px');
aud.setAttribute('scrolling', 'no');
aud.style.border = "0px";
document.body.appendChild(aud);

This is my answer to another question.

UPDATE 3: To customise the controls, you can use something like this.

Another possibility is to use the Maven Shade Plugin, e.g. to exclude a logging properties file used only locally in your IDE:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>${maven-shade-plugin-version}</version>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
            </goals>
            <configuration>
                <filters>
                    <filter>
                        <artifact>*:*</artifact>
                        <excludes>
                            <exclude>log4j2.xml</exclude>
                        </excludes>
                    </filter>
                </filters>
            </configuration>
        </execution>
    </executions>
</plugin>

This will however exclude the files from every artifact, so it might not be feasible in every situation.

I have a minor improvement on Ross Drew's answer.

For a small array, a simple loop is faster than the System.arraycopy approach, because of the overhead associated with setting up System.arraycopy. Therefore, it's better to fill the first few bytes of the array using a simple loop, and only move to System.arraycopy when the filled array has a certain size.

The optimal size of the initial loop will be JVM specific and system specific of course.

private static final int SMALL = 16;

public static void arrayFill(byte[] array, byte value) {
  int len = array.length;
  int lenB = len < SMALL ? len : SMALL;

  for (int i = 0; i < lenB; i++) {
    array[i] = value;
  }

  for (int i = SMALL; i < len; i += i) {
    System.arraycopy(array, 0, array, i, len < i + i ? len - i : i);
  }
}

Use __new__ to return value from a class.

As others suggest __repr__,__str__ or even __init__ (somehow) CAN give you what you want, But __new__ will be a semantically better solution for your purpose since you want the actual object to be returned and not just the string representation of it.

Read this answer for more insights into __str__ and __repr__ https://stackoverflow.com/a/19331543/4985585

class MyClass():
    def __new__(cls):
        return list() #or anything you want

>>> MyClass()
[]   #Returns a true list not a repr or string

When your path starts with a root dir i.e. C:\ in windows or / in Unix or in java resources path, it is considered to be an absolute path. Everything else is relative, so

new File("test.txt") is the same as new File("./test.txt")

new File("test/../test.txt") is the same as new File("./test/../test.txt")

The major difference between getAbsolutePath and getCanonicalPath is that the first one concatenates a parent and a child path, so it may contain dots: .. or .. getCanonicalPath will always return the same path for a particular file.

Note: File.equals uses an abstract form of a path (getAbsolutePath) to compare files, so this means that two File objects for the same might not be equal and Files are unsafe to use in collections like Map or Set.

Big warning on several of the solutions (and your own test) :

When you do : anything | xargs something

xargs will try to fit "as many arguments as possible" after "something", but then you may end up with multiple invocations of "something".

So your attempt: find ... | xargs tar czvf file.tgz may end up overwriting "file.tgz" at each invocation of "tar" by xargs, and you end up with only the last invocation! (the chosen solution uses a GNU -T special parameter to avoid the problem, but not everyone has that GNU tar available)

You could do instead:

find . -type f -print0 | xargs -0 tar -rvf backup.tar
gzip backup.tar

Proof of the problem on cygwin:

$ mkdir test
$ cd test
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs touch 
    # create the files
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs tar czvf archive.tgz
    # will invoke tar several time as it can'f fit 10000 long filenames into 1
$ tar tzvf archive.tgz | wc -l
60
    # in my own machine, I end up with only the 60 last filenames, 
    # as the last invocation of tar by xargs overwrote the previous one(s)

# proper way to invoke tar: with -r  (which append to an existing tar file, whereas c would overwrite it)
# caveat: you can't have it compressed (you can't add to a compressed archive)
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs tar rvf archive.tar #-r, and without z
$ gzip archive.tar
$ tar tzvf archive.tar.gz | wc -l
10000 
  # we have all our files, despite xargs making several invocations of the tar command

 

Note: that behavior of xargs is a well know diccifulty, and it is also why, when someone wants to do :

find .... | xargs grep "regex"

they intead have to write it:

find ..... | xargs grep "regex" /dev/null

That way, even if the last invocation of grep by xargs appends only 1 filename, grep sees at least 2 filenames (as each time it has: /dev/null, where it won't find anything, and the filename(s) appended by xargs after it) and thus will always display the file names when something maches "regex". Otherwise you may end up with the last results showing matches without a filename in front.

table-layout: fixed will get force the cells to fit the table (and not the other way around), e.g.:

<table style="border: 1px solid black; width: 100%; word-wrap:break-word;
              table-layout: fixed;">
  <tr>
    <td>
        aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
        bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
    </td>
  </tr>
</table>

Add MultipleActiveResultSets=true to the provider part of your connection string example in the file appsettings.json

"ConnectionStrings": {
"EmployeeDBConnection": "server=(localdb)\\MSSQLLocalDB;database=YourDatabasename;Trusted_Connection=true;MultipleActiveResultSets=true"}

Simple answer is that: Go to your console app's properties(project's properties).In the "Application" tab, just change the "Output type" to "Windows Application". That's all.

If you want to clear all item you stored in localStorage then

localStorage.clear();

Use this for clear all stored key.

If you want to clear/remove only specific key/value then you can use removeItem(key).

localStorage.removeItem('yourKey');

This exception can also occur when you have a custom view in your layout like this:

<com.example.MyView
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

and you change the view's package name from "com.example" to something different, but you forget to change it in the layout as well.

foo = [1, 2, 3]
bar = [4, 5, 6]

foo.append(bar) --> [1, 2, 3, [4, 5, 6]]
foo.extend(bar) --> [1, 2, 3, 4, 5, 6]

Gmail servers use SMTP Authentication under SSL or TLS. I think that there is no way to use the mail() function under that circumstances, so you might want to check these alternatives:

• PEAR::Mail
• phpMailer
• Nette\Mail

They all support SMTP auth under SSL.

You'll need to enable the php_openssl extension in your php.ini.

I was struggling for a while with this as my work computer (with Windows 10) created the default user library on a network drive, which would slow down R and RStudio to an unusable state.

In case this helps someone, this is the easiest way I found, without requiring admin rights:

• make sure the directory you want to install your packages into exists. If you want to respect the convention, use: C:\Users\username\R\win-library\rversion (for example, something like: C:\Users\janebloggs\R\win-library\3.6)
• create a .Renviron file in your home directory (which might be on the network drive?), and in it, write one single line that defines the R_LIBS_USER variable to be your custom path:

R_LIBS_USER=C:\Users\janebloggs\R\win-library\3.6

(feel free to add comments too, with lines starting with #)

If a .Renviron file exists, R will read it at startup and use the variables as they are defined in there, before running the code in the .Rprofile. You can read about it in help(Startup).

Now it should be persistent between sessions!

Note that the aspx and ascx solutions require a current HttpContext, so cannot be used asynchronously (eg in threads) without a lot of work.

As per documentation - "You can control the behaviors and visibility of the action bar with the ActionBar APIs, which were added in Android 3.0 (API level 11)."

So, ActionBar will not work for your target environment which is at API level 10 (Android 2.3.3).

Just in case, if you target for minimum API level 11 , you can change ActionBar's background color by defining custom style, as:

<resources>
    <style name="MyTheme" parent="@android:style/Theme.Holo.Light">
        <item name="android:actionBarStyle">@style/MyActionBar</item>
    </style>

    <style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
        <item name="android:background">ANY_HEX_COLOR_CODE</item>
    </style>
</resources>

And, set "MyTheme" as theme for application / activity.

You can use SHOW:

SHOW max_connections;

This returns the currently effective setting. Be aware that it can differ from the setting in postgresql.conf as there are a multiple ways to set run-time parameters in PostgreSQL. To reset the "original" setting from postgresql.conf in your current session:

RESET max_connections;

However, not applicable to this particular setting. The manual:

This parameter can only be set at server start.

To see all settings:

SHOW ALL;

There is also pg_settings:

The view pg_settings provides access to run-time parameters of the server. It is essentially an alternative interface to the SHOW and SET commands. It also provides access to some facts about each parameter that are not directly available from SHOW, such as minimum and maximum values.

For your original request:

SELECT *
FROM   pg_settings
WHERE  name = 'max_connections';

Finally, there is current_setting(), which can be nested in DML statements:

SELECT current_setting('max_connections');

Its little tricky in android studio there is no default folder for all screen size you need to create but with little trick.

• when you paste your image into drawable folder a popup will appear to ask about directory
• Add subfolder name after drawable like drawable-xxhdpi
• I will suggest you to paste image with highest resolution it will auto detect for other size.. thats it next time when you will paste it will ask to you about directory

i cant post image here so if still having any problem. here is tutorial..

A save method to determine the width and height unit of any element (no padding, no margin) is the following:

let div   = document.querySelector("div");
let style = getComputedStyle(div);

let width  = parseFloat(style.width.replace("px", ""));
let height = parseFloat(style.height.replace("px", ""));

For Swift with a UINavigationController:

override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(animated)
    if self.navigationController?.topViewController != self {

    }
}

Another option is if windows updates are turned totally off on your PC. In this case even if you download the USB driver & try update it manually as described above it will not work. The only way in this case is enabling windows updating drivers automatically. Once you enabled this, remove the non-working driver from device manager & connect you tablet to the PC via USB cable. The drivers will be automatically downloaded & installed by Windows. This way worked on my Windows 7 PC.
