I am trying to obtain a handle on one of the views in the Action Bar
I will assume that you mean something established via android:actionLayout
in your <item>
element of your <menu>
resource.
I have tried calling findViewById(R.id.menu_item)
To retrieve the View
associated with your android:actionLayout
, call findItem()
on the Menu
to retrieve the MenuItem
, then call getActionView()
on the MenuItem
. This can be done any time after you have inflated the menu resource.
import the HttpClientModule in your app.module.ts
import {HttpClientModule} from '@angular/common/http';
...
@NgModule({
...
imports: [
//other content,
HttpClientModule
]
})
some sources prefere to use .env.development
and .env.production
but that's not obligatory.
it seems that if your environment variable does not start like that so you will have problems
to include your environment variable just put on your code process.env.REACT_APP_VARIABLE
You don't have to install any external dependency
I believe TLSV1_ALERT_PROTOCOL_VERSION
is alerting you that the server doesn't want to talk TLS v1.0 to you. Try to specify TLS v1.2 only by sticking in these lines:
import ssl
context = ssl.SSLContext(ssl.PROTOCOL_TLSv1_2)
# Create HTTPS connection
c = HTTPSConnection("0.0.0.0", context=context)
Note, you may need sufficiently new versions of Python (2.7.9+ perhaps?) and possibly OpenSSL (I have "OpenSSL 1.0.2k 26 Jan 2017" and the above seems to work, YMMV)
Not sure if this is relevant to your question but it might be relevant to someone else in the future: I had a similar error. Turned out that the df was empty (had zero rows) and that is what was causing the error in my command.

This result is the first that pops-up in google, and is more broad than what's happening here. The following will apply to an express server:
I was trying to access resources from a nested folder.
Inside index.html
i had
<script src="./script.js"></script>
The static route was mounted at :
app.use(express.static(__dirname));
But the script.js
is located in the nested folder as in: js/myStaticApp/script.js
I just changed the static route to:
app.use(express.static(path.join(__dirname, "js")));
Now it works :)
You need to actually request the Location permission at runtime (notice the comments in your code stating this).
Here is tested and working code to request the Location permission.
Be sure to import android.Manifest
:
import android.Manifest;
Then put this code in the Activity:
public static final int MY_PERMISSIONS_REQUEST_LOCATION = 99;
public boolean checkLocationPermission() {
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.ACCESS_FINE_LOCATION)) {
// Show an explanation to the user *asynchronously* -- don't block
// this thread waiting for the user's response! After the user
// sees the explanation, try again to request the permission.
new AlertDialog.Builder(this)
.setTitle(R.string.title_location_permission)
.setMessage(R.string.text_location_permission)
.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
//Prompt the user once explanation has been shown
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
MY_PERMISSIONS_REQUEST_LOCATION);
}
})
.create()
.show();
} else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
MY_PERMISSIONS_REQUEST_LOCATION);
}
return false;
} else {
return true;
}
}
@Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_LOCATION: {
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay! Do the
// location-related task you need to do.
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
//Request location updates:
locationManager.requestLocationUpdates(provider, 400, 1, this);
}
} else {
// permission denied, boo! Disable the
// functionality that depends on this permission.
}
return;
}
}
}
Then call the checkLocationPermission()
method in onCreate()
:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//.........
checkLocationPermission();
}
You can then use onResume()
and onPause()
exactly as it is in the question.
Here is a condensed version that is a bit more clean:
@Override
protected void onResume() {
super.onResume();
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
locationManager.requestLocationUpdates(provider, 400, 1, this);
}
}
@Override
protected void onPause() {
super.onPause();
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
locationManager.removeUpdates(this);
}
}
Using Moshi:
When building your Retrofit Service add .asLenient() to your MoshiConverterFactory. You don't need a ScalarsConverter. It should look something like this:
return Retrofit.Builder()
.client(okHttpClient)
.baseUrl(ENDPOINT)
.addConverterFactory(MoshiConverterFactory.create().asLenient())
.build()
.create(UserService::class.java)
For anyone wondering how to do it in cordova hybrid app:
go to index.js ->
inside the function onDeviceReady() write :
subscribe();
(It's important to write it at the top of the function!)
then, in the same file (index.js) find :
function subscribe(){
FirebasePlugin.subscribe("write_here_your_topic", function(){
},function(error){
logError("Failed to subscribe to topic", error);
});
}
and write your own topic here ->
"write_here_your_topic"
Turn off Miui Optimizations on Developer Settings, then Restart the phone. it worked for me. Settings > Additional Settings > Developer Options > MIUI Optimization
I write this code and It's worked for me .
public static string ExcutePushNotification(string title, string msg, string fcmToken, object data)
{
var serverKey = "AAAA*******************";
var senderId = "3333333333333";
var result = "-1";
var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://fcm.googleapis.com/fcm/send");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Headers.Add(string.Format("Authorization: key={0}", serverKey));
httpWebRequest.Headers.Add(string.Format("Sender: id={0}", senderId));
httpWebRequest.Method = "POST";
var payload = new
{
notification = new
{
title = title,
body = msg,
sound = "default"
},
data = new
{
info = data
},
to = fcmToken,
priority = "high",
content_available = true,
};
var serializer = new JavaScriptSerializer();
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = serializer.Serialize(payload);
streamWriter.Write(json);
streamWriter.Flush();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
result = streamReader.ReadToEnd();
}
return result;
}
After spending hours on this issue I finally realised the problem when I intentionally corrupted the format of the "google-services.json" and my build still succeeded. The compiler does not notice the changes in this file. I tried many things, "reload from disk", gradle task "cleanBuildCache", new virtual device, uninstalling/reinstalling the app etc but none worked.
For me the solution was in AndroidStudio -> Build -> Clean Project
and Build -> Rebuild Project
PS: Also make sure "google-services.json" is in the "app" folder.
Use a server implementation to send messages to your client and use data type of messages rather than notification type of messages.
This will help you get a callback to onMessageReceived
irrespective if your app is in background or foreground and you can generate your custom notification then
The wording of the error message corresponds to what you get from Google Chrome when you run JSON.parse('<...')
. I know you said the server is setting Content-Type:application/json
, but I am led to believe the response body is actually HTML.
Feed.js:94 undefined "parsererror" "SyntaxError: Unexpected token < in JSON at position 0"
with the line
console.error(this.props.url, status, err.toString())
underlined.
The err
was actually thrown within jQuery
, and passed to you as a variable err
. The reason that line is underlined is simply because that is where you are logging it.
I would suggest that you add to your logging. Looking at the actual xhr
(XMLHttpRequest) properties to learn more about the response. Try adding console.warn(xhr.responseText)
and you will most likely see the HTML that is being received.
there is component ready to use (rc5 compatible)
ng2-steps
which uses Compiler
to inject component to step container
and service for wiring everything together (data sync)
import { Directive , Input, OnInit, Compiler , ViewContainerRef } from '@angular/core';
import { StepsService } from './ng2-steps';
@Directive({
selector:'[ng2-step]'
})
export class StepDirective implements OnInit{
@Input('content') content:any;
@Input('index') index:string;
public instance;
constructor(
private compiler:Compiler,
private viewContainerRef:ViewContainerRef,
private sds:StepsService
){}
ngOnInit(){
//Magic!
this.compiler.compileComponentAsync(this.content).then((cmpFactory)=>{
const injector = this.viewContainerRef.injector;
this.viewContainerRef.createComponent(cmpFactory, 0, injector);
});
}
}
You have your storyboard set up to expect an outlet called tableView
but the actual outlet name is myTableView
.
If you delete the connection in the storyboard and reconnect to the right variable name, it should fix the problem.
NumPy 1.7.0 (when numpy.pad
was added) is pretty old now (it was released in 2013) so even though the question asked for a way without using that function I thought it could be useful to know how that could be achieved using numpy.pad
.
It's actually pretty simple:
>>> import numpy as np
>>> a = np.array([[ 1., 1., 1., 1., 1.],
... [ 1., 1., 1., 1., 1.],
... [ 1., 1., 1., 1., 1.]])
>>> np.pad(a, [(0, 1), (0, 1)], mode='constant')
array([[ 1., 1., 1., 1., 1., 0.],
[ 1., 1., 1., 1., 1., 0.],
[ 1., 1., 1., 1., 1., 0.],
[ 0., 0., 0., 0., 0., 0.]])
In this case I used that 0
is the default value for mode='constant'
. But it could also be specified by passing it in explicitly:
>>> np.pad(a, [(0, 1), (0, 1)], mode='constant', constant_values=0)
array([[ 1., 1., 1., 1., 1., 0.],
[ 1., 1., 1., 1., 1., 0.],
[ 1., 1., 1., 1., 1., 0.],
[ 0., 0., 0., 0., 0., 0.]])
Just in case the second argument ([(0, 1), (0, 1)]
) seems confusing: Each list item (in this case tuple) corresponds to a dimension and item therein represents the padding before (first element) and after (second element). So:
[(0, 1), (0, 1)]
^^^^^^------ padding for second dimension
^^^^^^-------------- padding for first dimension
^------------------ no padding at the beginning of the first axis
^--------------- pad with one "value" at the end of the first axis.
In this case the padding for the first and second axis are identical, so one could also just pass in the 2-tuple:
>>> np.pad(a, (0, 1), mode='constant')
array([[ 1., 1., 1., 1., 1., 0.],
[ 1., 1., 1., 1., 1., 0.],
[ 1., 1., 1., 1., 1., 0.],
[ 0., 0., 0., 0., 0., 0.]])
In case the padding before and after is identical one could even omit the tuple (not applicable in this case though):
>>> np.pad(a, 1, mode='constant')
array([[ 0., 0., 0., 0., 0., 0., 0.],
[ 0., 1., 1., 1., 1., 1., 0.],
[ 0., 1., 1., 1., 1., 1., 0.],
[ 0., 1., 1., 1., 1., 1., 0.],
[ 0., 0., 0., 0., 0., 0., 0.]])
Or if the padding before and after is identical but different for the axis, you could also omit the second argument in the inner tuples:
>>> np.pad(a, [(1, ), (2, )], mode='constant')
array([[ 0., 0., 0., 0., 0., 0., 0., 0., 0.],
[ 0., 0., 1., 1., 1., 1., 1., 0., 0.],
[ 0., 0., 1., 1., 1., 1., 1., 0., 0.],
[ 0., 0., 1., 1., 1., 1., 1., 0., 0.],
[ 0., 0., 0., 0., 0., 0., 0., 0., 0.]])
However I tend to prefer to always use the explicit one, because it's just to easy to make mistakes (when NumPys expectations differ from your intentions):
>>> np.pad(a, [1, 2], mode='constant')
array([[ 0., 0., 0., 0., 0., 0., 0., 0.],
[ 0., 1., 1., 1., 1., 1., 0., 0.],
[ 0., 1., 1., 1., 1., 1., 0., 0.],
[ 0., 1., 1., 1., 1., 1., 0., 0.],
[ 0., 0., 0., 0., 0., 0., 0., 0.],
[ 0., 0., 0., 0., 0., 0., 0., 0.]])
Here NumPy thinks you wanted to pad all axis with 1 element before and 2 elements after each axis! Even if you intended it to pad with 1 element in axis 1 and 2 elements for axis 2.
I used lists of tuples for the padding, note that this is just "my convention", you could also use lists of lists or tuples of tuples, or even tuples of arrays. NumPy just checks the length of the argument (or if it doesn't have a length) and the length of each item (or if it has a length)!
You have to update the php.ini config file with in your host provider's server, trust me on this, more than likely there is nothing wrong with your code. It took me almost a month and a half to realize that most hosting servers are not up to date on php.ini files, eg. php 5.5 or later, I believe.
Improper package names can also cause the above error. As of Android Gradle plugin 3.2 (as far as I can tell) CamelCase package names will be inferred improperly as classes
, which will break the generated binding object.
Example:
src
|
-> FooPackage
|
-> Bar.java
will be generated wrongly as
import src.FooPackage
...
public abstract class MyBinding extends ViewDataBinding {
@NonNull
public final FooPackage.Bar mInstance;
...
}
This obviously doesn't make any sense.
Refactor FooPackage
to foopackage
according to java conventions and be saved. You will then get:
import src.foopackage.Bar
...
public abstract class MyBinding extends ViewDataBinding {
@NonNull
public final Bar mInstance;
...
}
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.
This is how I solved this issue:
First of all, tf.train.GradientDescentOptimizer
is designed to use a constant learning rate for all variables in all steps. TensorFlow also provides out-of-the-box adaptive optimizers including the tf.train.AdagradOptimizer
and the tf.train.AdamOptimizer
, and these can be used as drop-in replacements.
However, if you want to control the learning rate with otherwise-vanilla gradient descent, you can take advantage of the fact that the learning_rate
argument to the tf.train.GradientDescentOptimizer
constructor can be a Tensor
object. This allows you to compute a different value for the learning rate in each step, for example:
learning_rate = tf.placeholder(tf.float32, shape=[])
# ...
train_step = tf.train.GradientDescentOptimizer(
learning_rate=learning_rate).minimize(mse)
sess = tf.Session()
# Feed different values for learning rate to each training step.
sess.run(train_step, feed_dict={learning_rate: 0.1})
sess.run(train_step, feed_dict={learning_rate: 0.1})
sess.run(train_step, feed_dict={learning_rate: 0.01})
sess.run(train_step, feed_dict={learning_rate: 0.01})
Alternatively, you could create a scalar tf.Variable
that holds the learning rate, and assign it each time you want to change the learning rate.
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.addHeaderView(yourview);
In a simple way the permission can be granted using manifest.xml file, but it was ok till the api level 23 sdk version 6, after from here, if we want to get the permission we have to ask for the use to allow the permission which are needed.
Just add this code in the mainActivity.java
Override
public void onClick(View view) {
// Request the permission
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{Manifest.permission.CAMERA},
PERMISSION_REQUEST_CAMERA);
Replace CAMERA or add with WRITE_EXTERNAL_STORAGE if you want, and with the unique code.
new String[]{Manifest.permission.CAMERA,
Manifest.permission.WRITE_EXTERNAL_STORAGE},
101);
This is the simple code to get permission.
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
If you simply want to check for permissions (rather than request for permissions), I wrote a simple extension like so:
fun BaseActivity.checkPermission(permissionName: String): Boolean {
return if (Build.VERSION.SDK_INT >= 23) {
val granted =
ContextCompat.checkSelfPermission(this, permissionName)
granted == PackageManager.PERMISSION_GRANTED
} else {
val granted =
PermissionChecker.checkSelfPermission(this, permissionName)
granted == PermissionChecker.PERMISSION_GRANTED
}
}
Now, if I want to check for a permission I can simply pass in a permission like so:
checkPermission(Manifest.permission.READ_CONTACTS)
change your flag Windowmanger flag "TYPE_SYSTEM_OVERLAY" to "TYPE_APPLICATION_OVERLAY" in your project to make compatible with Android O
WindowManager.LayoutParams.TYPE_PHONE
to WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY
ACCESS_COARSE_LOCATION
, ACCESS_FINE_LOCATION
, and WRITE_EXTERNAL_STORAGE
are all part of the Android 6.0 runtime permission system. In addition to having them in the manifest as you do, you also have to request them from the user at runtime (using requestPermissions()
) and see if you have them (using checkSelfPermission()
).
One workaround in the short term is to drop your targetSdkVersion
below 23.
But, eventually, you will want to update your app to use the runtime permission system.
For example, this activity works with five permissions. Four are runtime permissions, though it is presently only handling three (I wrote it before WRITE_EXTERNAL_STORAGE
was added to the runtime permission roster).

(from this sample project)
For the requestPermissions() function, should the parameters just be "ACCESS_COARSE_LOCATION"? Or should I include the full name "android.permission.ACCESS_COARSE_LOCATION"?
I would use the constants defined on Manifest.permission
, as shown above.
Also, what is the request code?
That will be passed back to you as the first parameter to onRequestPermissionsResult()
, so you can tell one requestPermissions()
call from another.
NavigationView
has a method called setItemTextColor()
. It uses a ColorStateList
.
// FOR NAVIGATION VIEW ITEM TEXT COLOR
int[][] state = new int[][] {
new int[] {-android.R.attr.state_enabled}, // disabled
new int[] {android.R.attr.state_enabled}, // enabled
new int[] {-android.R.attr.state_checked}, // unchecked
new int[] { android.R.attr.state_pressed} // pressed
};
int[] color = new int[] {
Color.WHITE,
Color.WHITE,
Color.WHITE,
Color.WHITE
};
ColorStateList csl = new ColorStateList(state, color);
// FOR NAVIGATION VIEW ITEM ICON COLOR
int[][] states = new int[][] {
new int[] {-android.R.attr.state_enabled}, // disabled
new int[] {android.R.attr.state_enabled}, // enabled
new int[] {-android.R.attr.state_checked}, // unchecked
new int[] { android.R.attr.state_pressed} // pressed
};
int[] colors = new int[] {
Color.WHITE,
Color.WHITE,
Color.WHITE,
Color.WHITE
};
ColorStateList csl2 = new ColorStateList(states, colors);
Here is where I got that answer. And then right after assigning my NavigationView:
if (nightMode == 0) {
navigationView.setItemTextColor(csl);
navigationView.setItemIconTintList(csl2);
}
i also faced similar issue. I could able to solve this by setting JAVA_HOME in Environment variable in windows. Setting JAVA_HOME in batch file is not working in this case.
If usb is not working you should checkout debugging over bluetooth (Without Rooting)

For a minimum API level of 15, you'd want to use AppCompatActivity
. So for example, your MainActivity
would look like this:
public class MainActivity extends AppCompatActivity {
....
....
}
To use the AppCompatActivity
, make sure you have the Google Support Library downloaded (you can check this in your Tools -> Android -> SDK manager). Then just include the gradle dependency in your app's gradle.build file:
compile 'com.android.support:appcompat-v7:22:2.0'
You can use this AppCompat
as your main Activity
, which can then be used to launch Fragments or other Activities (this depends on what kind of app you're building).
The BigNerdRanch book is a good resource, but yeah, it's outdated. Read it for general information on how Android works, but don't expect the specific classes they use to be up to date.
API 23 provides the following method:
navigationView.setCheckedItem(R.id.nav_item_id);
However, for some reason this function did not cause the code behind the navigation item to run. The method certainly highlights the item in the navigation drawer, or 'checks' it, but it does not seem to call the OnNavigationItemSelectedListener
resulting in a blank screen on start-up if your start-up screen depends on navigation drawer selections. It is possible to manually call the listener, but it seems hacky:
if (savedInstanceState == null) this.onNavigationItemSelected(navigationView.getMenu().getItem(0));
The above code assumes:
NavigationView.OnNavigationItemSelectedListener
in your activitynavigationView.setNavigationItemSelectedListener(this);
For SDK >= 23, please add setLargeIcon
notification = new Notification.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setLargeIcon(context.getResources(), R.drawable.lg_logo))
.setContentTitle(title)
.setStyle(new Notification.BigTextStyle().bigText(msg))
.setAutoCancel(true)
.setContentText(msg)
.setContentIntent(contentIntent)
.setSound(sound)
.build();
If you have enabled actuator feature (spring-boot-starter-actuator), additional exclude should be added in application.yml:
spring:
autoconfigure:
exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration,org.springframework.boot.actuate.autoconfigure.security.servlet.ManagementWebSecurityAutoConfiguration
Tested in Spring Boot version 2.3.4.RELEASE.
For those who are getting Error Unknown URI: content://downloads/public_downloads
.
I managed to solve this by getting a hint given by @Commonsware in this answer. I found out the class FileUtils on GitHub.
Here InputStream
methods are used to fetch file from Download
directory.
// DownloadsProvider
else if (isDownloadsDocument(uri)) {
final String id = DocumentsContract.getDocumentId(uri);
if (id != null && id.startsWith("raw:")) {
return id.substring(4);
}
String[] contentUriPrefixesToTry = new String[]{
"content://downloads/public_downloads",
"content://downloads/my_downloads",
"content://downloads/all_downloads"
};
for (String contentUriPrefix : contentUriPrefixesToTry) {
Uri contentUri = ContentUris.withAppendedId(Uri.parse(contentUriPrefix), Long.valueOf(id));
try {
String path = getDataColumn(context, contentUri, null, null);
if (path != null) {
return path;
}
} catch (Exception e) {}
}
// path could not be retrieved using ContentResolver, therefore copy file to accessible cache using streams
String fileName = getFileName(context, uri);
File cacheDir = getDocumentCacheDir(context);
File file = generateFileName(fileName, cacheDir);
String destinationPath = null;
if (file != null) {
destinationPath = file.getAbsolutePath();
saveFileFromUri(context, uri, destinationPath);
}
return destinationPath;
}
I decided to write my own script to ease some of the pain of setting up projects.
Run the following inside your project root:
wget -qO- https://raw.githubusercontent.com/defaye/bootstrap-laravel/master/bootstrap.sh | sh
Wait for the bootstrapping to complete and you're good to go.
Review the script before use.
I've just managed to setup new TabLayout, so here are the quick steps to do this (????)?*:???
Add dependencies inside your build.gradle file:
dependencies {
compile 'com.android.support:design:23.1.1'
}
Add TabLayout inside your layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"/>
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
Setup your Activity like this:
import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
public class TabLayoutActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pull_to_refresh);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
if (toolbar != null) {
setSupportActionBar(toolbar);
}
viewPager.setAdapter(new SectionPagerAdapter(getSupportFragmentManager()));
tabLayout.setupWithViewPager(viewPager);
}
public class SectionPagerAdapter extends FragmentPagerAdapter {
public SectionPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new FirstTabFragment();
case 1:
default:
return new SecondTabFragment();
}
}
@Override
public int getCount() {
return 2;
}
@Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "First Tab";
case 1:
default:
return "Second Tab";
}
}
}
}
Check whether you have matching IDs in both Java and XML
I recommend modify the solution of @Xaver Kapeller with 2 things below to avoid a problem after you cleared the searched text (the filter didn't work anymore) due to the list back of adapter has smaller size than filter list and the IndexOutOfBoundsException happened. So the code need to modify as below
public void addItem(int position, ExampleModel model) {
if(position >= mModel.size()) {
mModel.add(model);
notifyItemInserted(mModel.size()-1);
} else {
mModels.add(position, model);
notifyItemInserted(position);
}
}
And modify also in moveItem functionality
public void moveItem(int fromPosition, int toPosition) {
final ExampleModel model = mModels.remove(fromPosition);
if(toPosition >= mModels.size()) {
mModels.add(model);
notifyItemMoved(fromPosition, mModels.size()-1);
} else {
mModels.add(toPosition, model);
notifyItemMoved(fromPosition, toPosition);
}
}
Hope that It could help you!
*X*YZ* = string contains X and contains YZ
@".*X.*YZ"
X*YZ*P = string starts with X, contains YZ and ends with P.
@"^X.*YZ.*P$"
It happens because the component is rendered before the async data arrived, you should control before to render.
I resolved it in this way:
render() {
let partners = this.props && this.props.partners.length > 0 ?
this.props.partners.map(p=>
<li className = "partners" key={p.id}>
<img src={p.img} alt={p.name}/> {p.name} </li>
) : <span></span>;
return (
<div>
<ul>{partners}</ul>
</div>
);
}
this.props && this.props.partners.length > 0 ?
You can use Toolbar inside the fragment and it is easy to handle. First add Toolbar to layout of the fragment
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:minHeight="?attr/actionBarSize"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:background="?attr/colorPrimaryDark">
</android.support.v7.widget.Toolbar>
Inside the onCreateView Method in the fragment you can handle the toolbar like this.
Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
toolbar.setTitle("Title");
toolbar.setNavigationIcon(R.drawable.ic_arrow_back);
IT will set the toolbar,title and the back arrow navigation to toolbar.You can set any icon to setNavigationIcon method.
If you need to trigger any event when click toolbar navigation icon you can use this.
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//handle any click event
});
If your activity have navigation drawer you may need to open that when click the navigation back button. you can open that drawer like this.
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DrawerLayout drawer = (DrawerLayout) getActivity().findViewById(R.id.drawer_layout);
drawer.openDrawer(Gravity.START);
}
});
Full code is here
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//inflate the layout to the fragement
view = inflater.inflate(R.layout.layout_user,container,false);
//initialize the toolbar
Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
toolbar.setTitle("Title");
toolbar.setNavigationIcon(R.drawable.ic_arrow_back);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//open navigation drawer when click navigation back button
DrawerLayout drawer = (DrawerLayout) getActivity().findViewById(R.id.drawer_layout);
drawer.openDrawer(Gravity.START);
}
});
return view;
}
Please rather try:
$JAVA_HOME/bin/java -version
Maven uses $JAVA_HOME
for classpath resolution of JRE libs.
To be sure to use a certain JDK, set it explicitly before compiling, for example:
export JAVA_HOME=/usr/java/jdk1.7.0_51
Isn't there a version < 1.7 and you're using Maven 3.3.1? In this case the reason is a new prerequisite: https://issues.apache.org/jira/browse/MNG-5780
for swift 3 you just need to write the following line of code
_ = navigationController?.popViewController(animated: true)
In your public View getView
method change return null;
to return convertView;
.
Here's a natural way to do it with styles:
If your AppTheme
is inherited from Theme.MaterialComponents
, then:
<style name="AlertDialogTheme" parent="ThemeOverlay.MaterialComponents.Dialog.Alert">
<item name="buttonBarNegativeButtonStyle">@style/NegativeButtonStyle</item>
<item name="buttonBarPositiveButtonStyle">@style/PositiveButtonStyle</item>
</style>
<style name="NegativeButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
<item name="android:textColor">#f00</item>
</style>
<style name="PositiveButtonStyle" parent="Widget.MaterialComponents.Button.TextButton.Dialog">
<item name="android:textColor">#00f</item>
</style>
If your AppTheme
is inherited from Theme.AppCompat
:
<style name="AlertDialogTheme" parent="ThemeOverlay.AppCompat.Dialog.Alert">
<item name="buttonBarNegativeButtonStyle">@style/NegativeButtonStyle</item>
<item name="buttonBarPositiveButtonStyle">@style/PositiveButtonStyle</item>
</style>
<style name="NegativeButtonStyle" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog">
<item name="android:textColor">#f00</item>
</style>
<style name="PositiveButtonStyle" parent="Widget.AppCompat.Button.ButtonBar.AlertDialog">
<item name="android:textColor">#00f</item>
</style>
Use your AlertDialogTheme
in your AppTheme
<item name="alertDialogTheme">@style/AlertDialogTheme</item>
or in constructor
androidx.appcompat.app.AlertDialog.Builder(context, R.style.AlertDialogTheme)
Adding to the accepted answer, there is one more reason due to which elevation may not work as expected if the Bluelight filter feature on the phone is ON.
I was facing this issue when the elevation appeared completely distorted and unbearable in my device. But the elevation was fine in the preview. Turning off the Bluelight filter on phone resolved the issue.
So even after setting
android:outlineProvider="bounds"
The elevation is not working properly, then you can try to tinker with phone's color settings.
https://services.gradle.org/distributions/gradle-2.1-all.zip
open this link in the browser and download the zip file and extract it to folder
Before extraction please delete the old folder whose name ends gradle-2.1-all and then you can start extracting
if you are window user extract it to this folder
C:\Users{Your-Name}.gradle\wrapper\dists
after that just restart your android studio. I hope it works it works for me .
SearchView
can be added as actionView
in menu using
app:useActionClass = "android.support.v7.widget.SearchView" .
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="rohksin.com.searchviewdemo.MainActivity">
<item
android:id="@+id/searchBar"
app:showAsAction="always"
app:actionViewClass="android.support.v7.widget.SearchView"
/>
</menu>
SearchView.OnQueryTextListener
has two abstract methods. So your activity skeleton would now look like this after implementing SearchView text listener.
YourActivity extends AppCompatActivity implements SearchView.OnQueryTextListener{
public boolean onQueryTextSubmit(String query)
public boolean onQueryTextChange(String newText)
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
MenuItem searchItem = menu.findItem(R.id.searchBar);
SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setQueryHint("Search People");
searchView.setOnQueryTextListener(this);
searchView.setIconified(false);
return true;
}
This is how you can implement abstract methods of the listener.
@Override
public boolean onQueryTextSubmit(String query) {
// This method can be used when a query is submitted eg. creating search history using SQLite DB
Toast.makeText(this, "Query Inserted", Toast.LENGTH_SHORT).show();
return true;
}
@Override
public boolean onQueryTextChange(String newText) {
adapter.filter(newText);
return true;
}
You can come up with your own logic based on your requirement. Here is the sample code snippet to show the list of Name which contains the text typed in the SearchView
.
public void filter(String queryText)
{
list.clear();
if(queryText.isEmpty())
{
list.addAll(copyList);
}
else
{
for(String name: copyList)
{
if(name.toLowerCase().contains(queryText.toLowerCase()))
{
list.add(name);
}
}
}
notifyDataSetChanged();
}
Full working code sample can be found > HERE
You can also check out the code on SearchView with an SQLite database in this Music App
You should initialize yours recordings. You are passing to adapter null
ArrayList<String> recordings = null; //You are passing this null
PopupWindow
can only be attached to an Activity
. In your case you are trying to add PopupWindow
to service
which is not right.
To solve this problem you can use a blank and transparent Activity
. On click of floating icon, launch the Activity
and on onCreate
of Activity
show the PopupWindow
.
On dismiss of PopupWindow
, you can finish
the transparent Activity
.
Hope this helps you.
First off it's important to understand that there are two kinds of "event listeners":
Scope event listeners registered via $on
:
$scope.$on('anEvent', function (event, data) {
...
});
Event handlers attached to elements via for example on
or bind
:
element.on('click', function (event) {
...
});
When $scope.$destroy()
is executed it will remove all listeners registered via $on
on that $scope.
It will not remove DOM elements or any attached event handlers of the second kind.
This means that calling $scope.$destroy()
manually from example within a directive's link function will not remove a handler attached via for example element.on
, nor the DOM element itself.
Note that remove
is a jqLite method (or a jQuery method if jQuery is loaded before AngularjS) and is not available on a standard DOM Element Object.
When element.remove()
is executed that element and all of its children will be removed from the DOM together will all event handlers attached via for example element.on
.
It will not destroy the $scope associated with the element.
To make it more confusing there is also a jQuery event called $destroy
. Sometimes when working with third-party jQuery libraries that remove elements, or if you remove them manually, you might need to perform clean up when that happens:
element.on('$destroy', function () {
scope.$destroy();
});
This depends on how the directive is "destroyed".
A normal case is that a directive is destroyed because ng-view
changes the current view. When this happens the ng-view
directive will destroy the associated $scope, sever all the references to its parent scope and call remove()
on the element.
This means that if that view contains a directive with this in its link function when it's destroyed by ng-view
:
scope.$on('anEvent', function () {
...
});
element.on('click', function () {
...
});
Both event listeners will be removed automatically.
However, it's important to note that the code inside these listeners can still cause memory leaks, for example if you have achieved the common JS memory leak pattern circular references
.
Even in this normal case of a directive getting destroyed due to a view changing there are things you might need to manually clean up.
For example if you have registered a listener on $rootScope
:
var unregisterFn = $rootScope.$on('anEvent', function () {});
scope.$on('$destroy', unregisterFn);
This is needed since $rootScope
is never destroyed during the lifetime of the application.
The same goes if you are using another pub/sub implementation that doesn't automatically perform the necessary cleanup when the $scope is destroyed, or if your directive passes callbacks to services.
Another situation would be to cancel $interval
/$timeout
:
var promise = $interval(function () {}, 1000);
scope.$on('$destroy', function () {
$interval.cancel(promise);
});
If your directive attaches event handlers to elements for example outside the current view, you need to manually clean those up as well:
var windowClick = function () {
...
};
angular.element(window).on('click', windowClick);
scope.$on('$destroy', function () {
angular.element(window).off('click', windowClick);
});
These were some examples of what to do when directives are "destroyed" by Angular, for example by ng-view
or ng-if
.
If you have custom directives that manage the lifecycle of DOM elements etc. it will of course get more complex.
To control the location of the title you may want to set a custom font as explained here (by twaddington): Link
Then to relocate the position of the text, in updateMeasureState()
you would add p.baselineShift += (int) (p.ascent() * R);
Similarly in updateDrawState()
add tp.baselineShift += (int) (tp.ascent() * R);
Where R is double between -1 and 1.

i am using version 26.0.1 :

I know I come late, but only recently I was able to implement such "addHeader" to the Adapter. In my FlexibleAdapter project you can call setHeader
on a Sectionable item, then you call showAllHeaders
. If you need only 1 header then the first item should have the header. If you delete this item, then the header is automatically linked to the next one.
Unfortunately footers are not covered (yet).
The FlexibleAdapter allows you to do much more than create headers/sections. You really should have a look: https://github.com/davideas/FlexibleAdapter.
In my case, it was InterfaceBuilder. I had copied some Views from another ViewController which messed up the constraints.
In InterfaceBuilder I had the red arrow error on the ViewController.
During execution the app crashed.
Another oh-so-easy mistake, which was the source of the problem for me: I’d written my own shouldComponentUpdate
method, which didn’t check the new state change I’d added.
In iOS10 there is new constant called UICollectionViewFlowLayout.automaticSize
(formerly UICollectionViewFlowLayoutAutomaticSize
), so instead:
self.flowLayout.estimatedItemSize = CGSize(width: 100, height: 100)
you can use this:
self.flowLayout.estimatedItemSize = UICollectionViewFlowLayout.automaticSize
It has better performance especially when cells in you collection view has constant wid
Accessing Flow Layout:
override func viewDidLoad() {
super.viewDidLoad()
if let flowLayout = collectionView?.collectionViewLayout as? UICollectionViewFlowLayout {
flowLayout.estimatedItemSize = UICollectionViewFlowLayout.automaticSize
}
}
Swift 5 Updated:
override func viewDidLoad() {
super.viewDidLoad()
if let flowLayout = collectionView?.collectionViewLayout as? UICollectionViewFlowLayout {
flowLayout.estimatedItemSize = UICollectionViewFlowLayout.automaticSize
}
}
Programming is simple. Use simple usecase:
interface IenumServiceGetOrderBy { id: number; label: string; key: any }
// OR
interface IenumServiceGetOrderBy { id: number; label: string; key: string | string[] }
// use interface like
const result: IenumServiceGetOrderBy[] =
[
{ id: 0, label: 'CId', key: 'contentId' },
{ id: 1, label: 'Modified By', key: 'modifiedBy' },
{ id: 4, label: 'Status > Type', key: ['contentStatusId', 'contentTypeId'] }
];
It just happend to me. I solved the problem by tracing backward from the point ng-click is coded. Found out that an extra
</div>
was placed in the html to prematurely close the div block that contains the ng-click.
Removed the extra
</div>
then everything is working fine.

}
}
//To call or execute function after some time
DispatchQueue.main.asyncAfter(deadline: .now() + 5.0) {
//Here call your function
}
//If you want to do changes in UI use this
DispatchQueue.main.async(execute: {
//Update UI
self.tableView.reloadData()
})
Building on what is mentioned in the comments, the simplest solution would be:
@RequestMapping(method = RequestMethod.PUT, consumes = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public Collection<BudgetDTO> updateConsumerBudget(@RequestBody SomeDto someDto) throws GeneralException, ParseException {
//whatever
}
class SomeDto {
private List<WhateverBudgerPerDateDTO> budgetPerDate;
//getters setters
}
The solution assumes that the HTTP request you are creating actually has
Content-Type:application/json
instead of text/plain
OnFragmentInteractionListener
is the default implementation for handling fragment to activity communication. This can be implemented based on your needs. Suppose if you need a function in your activity to be executed during a particular action within your fragment, you may make use of this callback method. If you don't need to have this interaction between your hosting activity
and fragment
, you may remove this implementation.
In short you should implement
the listener in your fragment hosting activity if you need the fragment-activity interaction like this
public class MainActivity extends Activity implements
YourFragment.OnFragmentInteractionListener {..}
and your fragment should have it defined like this
public interface OnFragmentInteractionListener {
// TODO: Update argument type and name
void onFragmentInteraction(Uri uri);
}
also provide definition for void onFragmentInteraction(Uri uri);
in your activity
or else just remove the listener
initialisation from your fragment's onAttach
if you dont have any fragment-activity interaction
I hope it will be helpful for others.
// put below code (method) in Adapter class
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
myList.clear();
if (charText.length() == 0) {
myList.addAll(arraylist);
}
else
{
for (MyBean wp : arraylist) {
if (wp.getName().toLowerCase(Locale.getDefault()).contains(charText)) {
myList.add(wp);
}
}
}
notifyDataSetChanged();
}
declare below code in adapter class
private ArrayList<MyBean> myList; // for loading main list
private ArrayList<MyBean> arraylist=null; // for loading filter data
below code in adapter Constructor
this.arraylist = new ArrayList<MyBean>();
this.arraylist.addAll(myList);
and below code in your activity class
final EditText searchET = (EditText)findViewById(R.id.search_et);
// Capture Text in EditText
searchET.addTextChangedListener(new TextWatcher() {
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
String text = searchET.getText().toString().toLowerCase(Locale.getDefault());
adapter.filter(text);
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1,
int arg2, int arg3) {
// TODO Auto-generated method stub
}
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
});
In my case, force run #notifyDataSetChanged in main ui thread will fix
public void refresh() {
clearSelection();
// notifyDataSetChanged must run in main ui thread, if run in not ui thread, it will not update until manually scroll recyclerview
((Activity) ctx).runOnUiThread(new Runnable() {
@Override
public void run() {
adapter.notifyDataSetChanged();
}
});
}
Swift is statically typed so the performSelector:
methods are to fall by the wayside.
Instead, use GCD to dispatch a suitable block to the relevant queue — in this case it'll presumably be the main queue since it looks like you're doing UIKit work.
EDIT: the relevant performSelector:
is also notably missing from the Swift version of the NSRunLoop
documentation ("1 Objective-C symbol hidden") so you can't jump straight in with that. With that and its absence from the Swiftified NSObject
I'd argue it's pretty clear what Apple is thinking here.
I think that you should make the reference to your config file
26399:C 16 Jan 08:51:13.413 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf
you can try to start your redis server like
./redis-server /path/to/redis-stable/redis.conf
Works great, minimal setup and no third parties.
According to Chrome's documentation:
Here's the updated workflow:What happens when you blackbox a script?
Exceptions thrown from library code will not pause (if Pause on exceptions is enabled), Stepping into/out/over bypasses the library code, Event listener breakpoints don't break in library code, The debugger will not pause on any breakpoints set in library code. The end result is you are debugging your application code instead of third party resources.

(glob pattern/human translation: jquery.*.js
)|
, like so: jquery\..*\.js|include\.postload\.js
(which acts like an "or this pattern", so to speak. Or keep adding them with the "Add" button.Bonus tip! I use Regex101 regularly (but there are many others: ) to quickly test my rusty regex patterns and find out where I'm wrong with the step-by-step regex debugger. If you are not yet "fluent" in Regular Expressions I recommend you start using sites that help you write and visualize them such as http://buildregex.com/ and https://www.debuggex.com/
You can also use the context menu when working in the Sources panel. When viewing a file, you can right-click in the editor and choose Blackbox Script. This will add the file to the list in the Settings panel:
It's an excellent tool to have:
Visual Event is an open-source Javascript bookmarklet which provides debugging information about events that have been attached to DOM elements. Visual Event shows:
- Which elements have events attached to them
- The type of events attached to an element
- The code that will be run with the event is triggered
- The source file and line number for where the attached function was defined (Webkit browsers and Opera only)
You can pause the code when you click somewhere in the page, or when the DOM is modified... and other kinds of JS breakpoints that will be useful to know. You should apply blackboxing here to avoid a nightmare.
In this instance, I want to know what exactly goes on when I click the button.
Open Dev Tools -> Sources tab, and on the right find Event
Listener Breakpoints
:
Expand Mouse
and select click
With Dev Tools activated, you can search the whole codebase (all code in all files) with ?+?+F or:
and searching #envio
or whatever the tag/class/id you think starts the party and you may get somewhere faster than anticipated.
Be aware sometimes there's not only an img
but lots of elements stacked, and you may not know which one triggers the code.
If this is a bit out of your knowledge, take a look at Chrome's tutorial on debugging.
If you're trying to take advantage of polymorphic behavior, you need to ensure that the methods visible to outside classes (that need polymorphism) have the same signature. That means they need to have the same name, number and order of parameters, as well as the parameter types.
In your case, you might do better to have a generic draw()
method, and rely on the subclasses (Rectangle
, Ellipse
) to implement the draw()
method as what you had been thinking of as "drawEllipse" and "drawRectangle".
you can use lftp, the swish army knife of downloading if you have bigger files you can add --use-pget-n=10
to command
lftp -c 'mirror --parallel=100 https://example.com/files/ ;exit'
When you really want to write an i-test for a spring data repository you can do it like this:
@RunWith(SpringRunner.class)
@DataJpaTest
@EnableJpaRepositories(basePackageClasses = WebBookingRepository.class)
@EntityScan(basePackageClasses = WebBooking.class)
public class WebBookingRepositoryIntegrationTest {
@Autowired
private WebBookingRepository repository;
@Test
public void testSaveAndFindAll() {
WebBooking webBooking = new WebBooking();
webBooking.setUuid("some uuid");
webBooking.setItems(Arrays.asList(new WebBookingItem()));
repository.save(webBooking);
Iterable<WebBooking> findAll = repository.findAll();
assertThat(findAll).hasSize(1);
webBooking.setId(1L);
assertThat(findAll).containsOnly(webBooking);
}
}

Check your Logcat
message and see your Manifest
file. There should be something missing like defining the Activity,
User permission`, etc.
You can delete the index by Kibana Console:
To get all index:
GET /_cat/indices?v
To delete a specific index:
DELETE /INDEX_NAME_TO_DELETE
Technically it is a memory allocation issue, however here are two more practical aspects of this. It has to do with two things: 1) Scope, when you define an object without a pointer you will no longer be able to access it after the code block it is defined in, whereas if you define a pointer with "new" then you can access it from anywhere you have a pointer to this memory until you call "delete" on the same pointer. 2) If you want to pass arguments to a function you want to pass a pointer or a reference in order to be more efficient. When you pass an Object then the object is copied, if this is an object that uses a lot of memory this might be CPU consuming (e.g. you copy a vector full of data). When you pass a pointer all you pass is one int (depending of implementation but most of them are one int).
Other than that you need to understand that "new" allocates memory on the heap that needs to be freed at some point. When you don't have to use "new" I suggest you use a regular object definition "on the stack".
You do not need to use docker run
.
You can do it with docker create
.
From the docs:
The
docker create
command creates a writeable container layer over the specified image and prepares it for running the specified command. The container ID is then printed toSTDOUT
. This is similar todocker run -d
except the container is never started.
So, you can do:
docker create -ti --name dummy IMAGE_NAME bash
docker cp dummy:/path/to/file /dest/to/file
docker rm -f dummy
Here, you never start the container. That looked beneficial to me.
Include the port number with the IP address.
For example:
http://19.18.20.101:5566
where 5566 is the port number.
This is because findViewById()
searches in the activity_main
layout, while the button is located in the fragment's layout fragment_main
.
Move that piece of code in the onCreateView()
method of the fragment:
//...
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
Button buttonClick = (Button)rootView.findViewById(R.id.button);
buttonClick.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
onButtonClick((Button) view);
}
});
Notice that now you access it through rootView
view:
Button buttonClick = (Button)rootView.findViewById(R.id.button);
otherwise you would get again NullPointerException.
You can use a position: absolute
inside a position: relative
Starting with Android 8.1 (API 27), apps must be granted the ACCESS_COARSE_LOCATION
(or ACCESS_FINE_LOCATION
) permission in order to obtain results from WifiInfo.getSSID()
or WifiInfo.getBSSID()
. Apps that target API 29 or higher (Android 10) must be granted ACCESS_FINE_LOCATION
.
This permission is also needed to obtain results from WifiManager.getConnectionInfo()
and WifiManager.getScanResults()
although it is not clear if this is new in 8.1 or was required previously.
Source: "BSSID/SSID can be used to deduce location, so require the same location permissions for access to these WifiInfo fields requested using WifiManager.getConnectionInfo() as for WifiManager.getScanResults()."
I had the same problem. My solution was to make all vectors numeric.
NullPointerException
s are among the easier exceptions to diagnose, frequently. Whenever you get an exception in Java and you see the stack trace ( that's what your second quote-block is called, by the way ), you read from top to bottom. Often, you will see exceptions that start in Java library code or in native implementations methods, for diagnosis you can just skip past those until you see a code file that you wrote.
Then you like at the line indicated and look at each of the objects ( instantiated classes ) on that line -- one of them was not created and you tried to use it. You can start by looking up in your code to see if you called the constructor on that object. If you didn't, then that's your problem, you need to instantiate that object by calling new Classname( arguments ). Another frequent cause of NullPointerException
s is accidentally declaring an object with local scope when there is an instance variable with the same name.
In your case, the exception occurred in your constructor for Workshop on line 75. <init>
means the constructor for a class. If you look on that line in your code, you'll see the line
denimjeansButton.addItemListener(this);
There are fairly clearly two objects on this line: denimjeansButton
and this
. this
is synonymous with the class instance you are currently in and you're in the constructor, so it can't be this
. denimjeansButton
is your culprit. You never instantiated that object. Either remove the reference to the instance variable denimjeansButton
or instantiate it.
I had the same error. I deleted the android repository from android sdk manager and reinstalled it. It worked.
This is how I fixed my issue, I am getting data in data variable and by using above solutions I was getting error could not load results
. I had to parse the results differently in processResults.
searchBar.select2({
ajax: {
url: "/search/live/results/",
dataType: 'json',
headers : {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')},
delay: 250,
type: 'GET',
data: function (params) {
return {
q: params.term, // search term
};
},
processResults: function (data) {
var arr = []
$.each(data, function (index, value) {
arr.push({
id: index,
text: value
})
})
return {
results: arr
};
},
cache: true
},
escapeMarkup: function (markup) { return markup; },
minimumInputLength: 1
});
I overcome this issue with if anybody interested. In myMain method i called my readasync method like
Dispatcher.BeginInvoke(new ThreadStart(() => ReadData()));
Everything is fine for me now.
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
First of all to see how many revisions you are behind locally, you should do a git fetch
to make sure you have the latest info from your remote.
The default output of git status
tells you how many revisions you are ahead or behind, but usually I find this too verbose:
$ git status
# On branch master
# Your branch and 'origin/master' have diverged,
# and have 2 and 1 different commit each, respectively.
#
nothing to commit (working directory clean)
I prefer git status -sb
:
$ git status -sb
## master...origin/master [ahead 2, behind 1]
In fact I alias this to simply git s
, and this is the main command I use for checking status.
To see the diff in the "ahead revisions" of master
, I can exclude the "behind revisions" from origin/master
:
git diff master..origin/master^
To see the diff in the "behind revisions" of origin/master
, I can exclude the "ahead revisions" from master
:
git diff origin/master..master^^
If there are 5 revisions ahead or behind it might be easier to write like this:
git diff master..origin/master~5
git diff origin/master..master~5
UPDATE
To see the ahead/behind revisions, the branch must be configured to track another branch. For me this is the default behavior when I clone a remote repository, and after I push a branch with git push -u remotename branchname
. My version is 1.8.4.3, but it's been working like this as long as I remember.
As of version 1.8, you can set the tracking branch like this:
git branch --track test-branch
As of version 1.7, the syntax was different:
git branch --set-upstream test-branch
If you have a vector
icon and not bitmap, you can set it this way.

You're saying that you need GPS location first if its available, but what you did is first you're getting location from network provider and then from GPS. This will get location from Network and GPS as well if both are available. What you can do is, write these cases in if..else if
block. Similar to-
if( !isGPSEnabled && !isNetworkEnabled) {
// Can't get location by any way
} else {
if(isGPSEnabled) {
// get location from GPS
} else if(isNetworkEnabled) {
// get location from Network Provider
}
}
So this will fetch location from GPS first (if available), else it will try to fetch location from Network Provider.
EDIT:
To make it better, I'll post a snippet. Consider it is in try-catch
:
boolean gps_enabled = false;
boolean network_enabled = false;
LocationManager lm = (LocationManager) mCtx
.getSystemService(Context.LOCATION_SERVICE);
gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
network_enabled = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
Location net_loc = null, gps_loc = null, finalLoc = null;
if (gps_enabled)
gps_loc = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (network_enabled)
net_loc = lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (gps_loc != null && net_loc != null) {
//smaller the number more accurate result will
if (gps_loc.getAccuracy() > net_loc.getAccuracy())
finalLoc = net_loc;
else
finalLoc = gps_loc;
// I used this just to get an idea (if both avail, its upto you which you want to take as I've taken location with more accuracy)
} else {
if (gps_loc != null) {
finalLoc = gps_loc;
} else if (net_loc != null) {
finalLoc = net_loc;
}
}
Now you check finalLoc
for null
, if not then return
it.
You can write above code in a function which returns the desired (finalLoc
) location. I think this might help.
If you don't want to implement the listener, you can set it up like this directly where you want it (call on your spinner after your adapter has been set):
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
switch (position) {
case 0:
Toast.makeText(parent.getContext(), "Spinner item 1!", Toast.LENGTH_SHORT).show();
break;
case 1:
Toast.makeText(parent.getContext(), "Spinner item 2!", Toast.LENGTH_SHORT).show();
break;
case 2:
Toast.makeText(parent.getContext(), "Spinner item 3!", Toast.LENGTH_SHORT).show();
break;
}
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
// sometimes you need nothing here
}
});
I didn't like bhavya's answer because of using AppDelegate
inside View Controllers and setting rootViewController
has no animation. And Trevor's answer has issue with flashing view controller on iOS8.
UPD 07/18/2015
AppDelegate inside View Controllers:
Changing AppDelegate state (properties) inside view controller breaks encapsulation.
Very simple hierarchy of objects in every iOS project:
AppDelegate (owns window
and rootViewController
)
ViewController (owns view
)
It's ok that objects from the top change objects at the bottom, because they are creating them. But it's not ok if objects on the bottom change objects on top of them (I described some basic programming/OOP principle : DIP (Dependency Inversion Principle : high level module must not depend on the low level module, but they should depend on abstractions)).
If any object will change any object in this hierarchy, sooner or later there will be a mess in the code. It might be ok on the small projects but it's no fun to dig through this mess on the bit projects =]

I replicate modal controller animations using UINavigationController
(tl;dr: check the project).
I'm using UINavigationController
to present all controllers in my app. Initially I displayed login view controller in navigation stack with plain push/pop animation. Than I decided to change it to modal with minimal changes.
How it works:
Initial view controller (or self.window.rootViewController
) is UINavigationController with ProgressViewController as a rootViewController
. I'm showing ProgressViewController because DataModel can take some time to initialize because it inits core data stack like in this article (I really like this approach).
AppDelegate is responsible for getting login status updates.
DataModel handles user login/logout and AppDelegate is observing it's userLoggedIn
property via KVO. Arguably not the best method to do this but it works for me. (Why KVO is bad, you can check in this or this article (Why Not Use Notifications? part).
ModalDismissAnimator and ModalPresentAnimator are used to customize default push animation.
How animators logic works:
AppDelegate sets itself as a delegate of self.window.rootViewController
(which is UINavigationController).
AppDelegate returns one of animators in -[AppDelegate navigationController:animationControllerForOperation:fromViewController:toViewController:]
if necessary.
Animators implement -transitionDuration:
and -animateTransition:
methods. -[ModalPresentAnimator animateTransition:]
:
- (void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext
{
UIViewController *toViewController = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];
[[transitionContext containerView] addSubview:toViewController.view];
CGRect frame = toViewController.view.frame;
CGRect toFrame = frame;
frame.origin.y = CGRectGetHeight(frame);
toViewController.view.frame = frame;
[UIView animateWithDuration:[self transitionDuration:transitionContext]
animations:^
{
toViewController.view.frame = toFrame;
} completion:^(BOOL finished)
{
[transitionContext completeTransition:![transitionContext transitionWasCancelled]];
}];
}
Test project is here.

<services>
<service name="YourServiceName">

FYI: My application's target framework is 4.5.1. IIS web site that I created to deploy this wcf service only has https binding enabled.
You can't use findViewById()
on menu items in onCreate()
because the menu layout isn't inflated yet. You could create a global Menu variable and initialize it in the onCreateOptionsMenu()
and then use it in your onClick()
.
private Menu menu;
In your onCreateOptionsMenu()
this.menu = menu;
In your button's onClick()
method
menu.getItem(0).setIcon(ContextCompat.getDrawable(this, R.drawable.ic_launcher));
Select your proper configuration for launching Application.
In my case i found mistake as below image:
I had just changed like:
May it will help to someone, Thanks :)
Your error

This post is high up when you google that error message, which I got when installing security patch KB4505224 on SQL Server 2017 Express i.e. None of the above worked for me, but did consume several hours trying.
The solution for me, partly from here was:
And all was well.
ListView myListView = (ListView) rootView.findViewById(R.id.myListView);
ArrayList<String> myStringArray1 = new ArrayList<String>();
myStringArray1.add("something");
adapter = new CustomAdapter(getActivity(), R.layout.row, myStringArray1);
myListView.setAdapter(adapter);
Try it like this
public OnClickListener moreListener = new OnClickListener() {
@Override
public void onClick(View v) {
adapter = null;
myStringArray1.add("Andrea");
adapter = new CustomAdapter(getActivity(), R.layout.row, myStringArray1);
myListView.setAdapter(adapter);

So this answer is a few years late but someone may appreciate it. Android has given us a new widget that makes using one navigation drawer with several activities easier.
android.support.design.widget.NavigationView is modular and has its own layout in the menu folder. The way that you use it is to wrap xml layouts the following way:
Root Layout is a android.support.v4.widget.DrawerLayout that contains two children: an <include ... />
for the layout that is being wrapped (see 2) and a android.support.design.widget.NavigationView.
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
layout="@layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="@layout/nav_header_main"
app:menu="@menu/activity_main_drawer" />
nav_header_main is just a LinearLayout with orientation = vertical for the header of your Navigation Drawar.
activity_main_drawer is a menu xml in your res/menu directory. It can contain items and groups of your choice. If you use the AndroidStudio Gallery the wizard will make a basic one for you and you can see what your options are.
App bar layout is usually now a android.support.design.widget.CoordinatorLayout and this will include two children: a android.support.design.widget.AppBarLayout (which contains a android.support.v7.widget.Toolbar) and an <include ... >
for your actual content (see 3).
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="yourpackage.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_main" />
Content layout can be whatever layout you want. This is the layout that contains the main content of the activity (not including the navigation drawer or app bar).
Now, the cool thing about all of this is that you can wrap each activity in these two layouts but have your NavigationView (see step 1) always point to activity_main_drawer (or whatever). This means that you will have the same(*) Navigation Drawer on all activities.
use ClipboardManager
ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clip = ClipData.newPlainText(label, text);
clipboard.setPrimaryClip(clip);
make sure you have imported android.content.ClipboardManager
and NOT android.text.ClipboardManager
. Latter is deprecated.
Check this link for Further information.
Maybe the span element is hidden. If that's the case then use the innerHtml property:
By.css:
String kk = wd.findElement(By.cssSelector("#customSelect_3 span.selectLabel"))
.getAttribute("innerHTML");
By.xpath:
String kk = wd.findElement(By.xpath(
"//*[@id='customSelect_3']/.//span[contains(@class,'selectLabel')]"))
.getAttribute("innerHTML");
"/.//" means "look under the selected element".
To add to @akilat90's update about sklearn.metrics.plot_confusion_matrix
:
You can use the ConfusionMatrixDisplay
class within sklearn.metrics
directly and bypass the need to pass a classifier to plot_confusion_matrix
. It also has the display_labels
argument, which allows you to specify the labels displayed in the plot as desired.
The constructor for ConfusionMatrixDisplay
doesn't provide a way to do much additional customization of the plot, but you can access the matplotlib axes obect via the ax_
attribute after calling its plot()
method. I've added a second example showing this.
I found it annoying to have to rerun a classifier over a large amount of data just to produce the plot with plot_confusion_matrix
. I am producing other plots off the predicted data, so I don't want to waste my time re-predicting every time. This was an easy solution to that problem as well.
Example:
from sklearn.metrics import confusion_matrix, ConfusionMatrixDisplay
cm = confusion_matrix(y_true, y_preds, normalize='all')
cmd = ConfusionMatrixDisplay(cm, display_labels=['business','health'])
cmd.plot()
Example using ax_
:
cm = confusion_matrix(y_true, y_preds, normalize='all')
cmd = ConfusionMatrixDisplay(cm, display_labels=['business','health'])
cmd.plot()
cmd.ax_.set(xlabel='Predicted', ylabel='True')
If you want to use the non-SSL source, try removing the HTTPS source first, and then adding the HTTP one:
sudo gem sources -r https://rubygems.org
sudo gem sources -a http://rubygems.org
UPDATE:
As mpapis states, this should be used only as a temporary workaround. There could be some security concerns if you're accessing RubyGems through the non-SSL source.
Once the workaround is not needed anymore, you should restore the SSL-source:
sudo gem sources -r http://rubygems.org
sudo gem sources -a https://rubygems.org
I think this working CodePen example that I created will show you exactly how to do what you want.
The template:
<section ng-app="app" ng-controller="MainCtrl">
<span class="label">Ordered By: {{orderByField}}, Reverse Sort: {{reverseSort}}</span><br><br>
<table class="table table-bordered">
<thead>
<tr>
<th>
<a href="#" ng-click="orderByField='firstName'; reverseSort = !reverseSort">
First Name <span ng-show="orderByField == 'firstName'"><span ng-show="!reverseSort">^</span><span ng-show="reverseSort">v</span></span>
</a>
</th>
<th>
<a href="#" ng-click="orderByField='lastName'; reverseSort = !reverseSort">
Last Name <span ng-show="orderByField == 'lastName'"><span ng-show="!reverseSort">^</span><span ng-show="reverseSort">v</span></span>
</a>
</th>
<th>
<a href="#" ng-click="orderByField='age'; reverseSort = !reverseSort">
Age <span ng-show="orderByField == 'age'"><span ng-show="!reverseSort">^</span><span ng-show="reverseSort">v</span></span>
</a>
</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="emp in data.employees|orderBy:orderByField:reverseSort">
<td>{{emp.firstName}}</td>
<td>{{emp.lastName}}</td>
<td>{{emp.age}}</td>
</tr>
</tbody>
</table>
</section>
The JavaScript code:
var app = angular.module('app', []);
app.controller('MainCtrl', function($scope) {
$scope.orderByField = 'firstName';
$scope.reverseSort = false;
$scope.data = {
employees: [{
firstName: 'John',
lastName: 'Doe',
age: 30
},{
firstName: 'Frank',
lastName: 'Burns',
age: 54
},{
firstName: 'Sue',
lastName: 'Banter',
age: 21
}]
};
});
Using React Hooks:
You can define a custom Hook that listens to the window resize
event, something like this:
import React, { useLayoutEffect, useState } from 'react';
function useWindowSize() {
const [size, setSize] = useState([0, 0]);
useLayoutEffect(() => {
function updateSize() {
setSize([window.innerWidth, window.innerHeight]);
}
window.addEventListener('resize', updateSize);
updateSize();
return () => window.removeEventListener('resize', updateSize);
}, []);
return size;
}
function ShowWindowDimensions(props) {
const [width, height] = useWindowSize();
return <span>Window size: {width} x {height}</span>;
}
The advantage here is the logic is encapsulated, and you can use this Hook anywhere you want to use the window size.
Using React classes:
You can listen in componentDidMount, something like this component which just displays the window dimensions (like <span>Window size: 1024 x 768</span>
):
import React from 'react';
class ShowWindowDimensions extends React.Component {
state = { width: 0, height: 0 };
render() {
return <span>Window size: {this.state.width} x {this.state.height}</span>;
}
updateDimensions = () => {
this.setState({ width: window.innerWidth, height: window.innerHeight });
};
componentDidMount() {
window.addEventListener('resize', this.updateDimensions);
}
componentWillUnmount() {
window.removeEventListener('resize', this.updateDimensions);
}
}
I hope this will work, I tried a lot of methods but this one worked for me in fragments
. just put this line in onCreateview/init.
getActivity().getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
If the function you called returns null, it means your phone number is not registered in your contact list.
If instead of the phone number you just need an unique number, you may use the sim card's serial number:
TelephonyManager telemamanger = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String getSimSerialNumber = telemamanger.getSimSerialNumber();
Simplified version
final EditText taskEditText = new EditText(this);
AlertDialog dialog = new AlertDialog.Builder(this)
.setTitle("Add a new task")
.setMessage("What do you want to do next?")
.setView(taskEditText)
.setPositiveButton("Add", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
String task = String.valueOf(taskEditText.getText());
SQLiteDatabase db = mHelper.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(TaskContract.TaskEntry.COL_TASK_TITLE, task);
db.insertWithOnConflict(TaskContract.TaskEntry.TABLE,
null,
values,
SQLiteDatabase.CONFLICT_REPLACE);
db.close();
updateUI();
}
})
.setNegativeButton("Cancel", null)
.create();
dialog.show();
return true;
in AndroidManifest.xml set theme holo like this:
<activity
android:name="your Fragment or activity"
android:label="@string/xxxxxx"
android:theme="@android:style/Theme.Holo" >
Use vh attributes. It means viewport height and is a percentage. So height: 90vh would mean 90% of the viewport height. This works in most modern browsers.
Eg.
div {
height: 90vh;
}
You can forego the rest of your silly 100% stuff on the body.
If you have a header you can also do some fun things like take it into account by using the calc function in CSS.
Eg.
div {
height: calc(100vh - 50px);
}
This will give you 100% of the viewport height, minus 50px for your header.
by selecting an option, I need to update the fragment that is currently visible.
A simple way of doing this is using a trick related to the FragmentPagerAdapter
implementation:
case R.id.addText:
Fragment page = getSupportFragmentManager().findFragmentByTag("android:switcher:" + R.id.pager + ":" + ViewPager.getCurrentItem());
// based on the current position you can then cast the page to the correct
// class and call the method:
if (ViewPager.getCurrentItem() == 0 && page != null) {
((FragmentClass1)page).updateList("new item");
}
return true;
Please rethink your variable naming convention, using as the variable name the name of the class is very confusing(so no ViewPager ViewPager
, use ViewPager mPager
for example).
If it's fixed layout you can do like that:
public void onClick(View v) {
ViewGroup parent = (ViewGroup) IdNumber.this.getParent();
EditText firstName = (EditText) parent.findViewById(R.id.display_name);
firstName.setText("Some Text");
}
If you want find the EditText in flexible layout, I will help you later. Hope this help.
You can try this
your_ddl_id.Items.Insert(0,new ListItem("Select","");
I think this method my solve your problem:
public static void attachFragment ( int fragmentHolderLayoutId, Fragment fragment, Context context, String tag ) {
FragmentManager manager = ( (AppCompatActivity) context ).getSupportFragmentManager ();
FragmentTransaction ft = manager.beginTransaction ();
if (manager.findFragmentByTag ( tag ) == null) { // No fragment in backStack with same tag..
ft.add ( fragmentHolderLayoutId, fragment, tag );
ft.addToBackStack ( tag );
ft.commit ();
}
else {
ft.show ( manager.findFragmentByTag ( tag ) ).commit ();
}
}
which was originally posted in This Question
Its work fine to me,You can try it.
protected void displayNotification() {
Log.i("Start", "notification");
// Invoking the default notification service //
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this);
mBuilder.setAutoCancel(true);
mBuilder.setContentTitle("New Message");
mBuilder.setContentText("You have "+unMber_unRead_sms +" new message.");
mBuilder.setTicker("New message from PayMe..");
mBuilder.setSmallIcon(R.drawable.icon2);
// Increase notification number every time a new notification arrives //
mBuilder.setNumber(unMber_unRead_sms);
// Creates an explicit intent for an Activity in your app //
Intent resultIntent = new Intent(this, FreesmsLog.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(FreesmsLog.class);
// Adds the Intent that starts the Activity to the top of the stack //
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);
// mBuilder.setOngoing(true);
Notification note = mBuilder.build();
note.defaults |= Notification.DEFAULT_VIBRATE;
note.defaults |= Notification.DEFAULT_SOUND;
mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// notificationID allows you to update the notification later on. //
mNotificationManager.notify(notificationID, mBuilder.build());
}
As far as I know the correct way to check it is:
if [ $(id -u) = "0" ]; then
echo "You are root"
else
echo "You are NOT root"
fi
See "Testing For Root" section here:
Here's a great scripted solution for logging people out remotely or locally. I'm using qwinsta to get session information and building an array out of the given output. This makes it really easy to iterate through each entry and log out only the actual users, and not the system or RDP listener itself which usually just throws an access denied error anyway.
$serverName = "Name of server here OR localhost"
$sessions = qwinsta /server $serverName| ?{ $_ -notmatch '^ SESSIONNAME' } | %{
$item = "" | Select "Active", "SessionName", "Username", "Id", "State", "Type", "Device"
$item.Active = $_.Substring(0,1) -match '>'
$item.SessionName = $_.Substring(1,18).Trim()
$item.Username = $_.Substring(19,20).Trim()
$item.Id = $_.Substring(39,9).Trim()
$item.State = $_.Substring(48,8).Trim()
$item.Type = $_.Substring(56,12).Trim()
$item.Device = $_.Substring(68).Trim()
$item
}
foreach ($session in $sessions){
if ($session.Username -ne "" -or $session.Username.Length -gt 1){
logoff /server $serverName $session.Id
}
}
In the first line of this script give $serverName the appropriate value or localhost if running locally. I use this script to kick users before an automated process attempts to move some folders around. Prevents "file in use" errors for me. Another note, this script will have to be ran as an administrator user otherwise you can get accessed denied trying to log someone out. Hope this helps!
UPDATE 2018 MAY:
Alternatively, you can embed Edge browser, but only targetting windows 10.
Some receivers expect EOL sequence, which is typically two characters \r\n
, so try in your code replace the line
unsigned char cmd[] = {'I', 'N', 'I', 'T', ' ', '\r', '\0'};
with
unsigned char cmd[] = "INIT\r\n";
BTW, the above way is probably more efficient. There is no need to quote every character.
just replace your line with this
notificationManager.notify(Unique_Integer_Number, notification);
hope it will help you.
Case C) is the fastest. Having this as an extension:
Public Module MyExtensions
<Extension()> _
Public Sub Add(Of T)(ByRef arr As T(), item As T)
Array.Resize(arr, arr.Length + 1)
arr(arr.Length - 1) = item
End Sub
End Module
Usage:
Dim arr As Integer() = {1, 2, 3}
Dim newItem As Integer = 4
arr.Add(newItem)
' --> duration for adding 100.000 items: 1 msec
' --> duration for adding 100.000.000 items: 1168 msec
My site configuration file is example.conf in sites-available folder So you can create a symbolic link as

As Michael Borgwardt writes in his answer here:
int diffInDays = (int)( (newerDate.getTime() - olderDate.getTime()) / (1000 * 60 * 60 * 24) )
Note that this works with UTC dates, so the difference may be a day off if you look at local dates. And getting it to work correctly with local dates requires a completely different approach due to daylight savings time.
Today I faced Fatal signal 11 (SIGSEGV), code 1, fault addr 0x8 in tid 18161
issue and I struggle half day to solve this.
I tried many things clearing cache and deleting .gradle file and all.
Finally I disable Instant Run
and now I am not getting this issue again.
Now my application is working after enabling instant run also. It may be the instant run problem, Try with disabling and enabling instant run
From this answer:
Go to Android Studio Settings or Preferences (for MAC) -> Build,Execution,Deployment -> Instant Run.
Then deselect the "Enable Instant Run" checkbox at the top.
For swift
var label = UILabel(frame: CGRect(x: 0, y: 0, width: 250, height: 50))
label.textAlignment = .left
label.text = "This is a Label"
self.view.addSubview(label)
First you need to define a LocationListener
to handle location changes.
private final LocationListener mLocationListener = new LocationListener() {
@Override
public void onLocationChanged(final Location location) {
//your code here
}
};
Then get the LocationManager
and ask for location updates
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mLocationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, LOCATION_REFRESH_TIME,
LOCATION_REFRESH_DISTANCE, mLocationListener);
}
And finally make sure that you have added the permission on the Manifest,
For using only network based location use this one
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
For GPS based location, this one
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
In General:
An example of an easy way to post XML data and get the response (as a string) would be the following function:
public string postXMLData(string destinationUrl, string requestXml)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
byte[] bytes;
bytes = System.Text.Encoding.ASCII.GetBytes(requestXml);
request.ContentType = "text/xml; encoding='utf-8'";
request.ContentLength = bytes.Length;
request.Method = "POST";
Stream requestStream = request.GetRequestStream();
requestStream.Write(bytes, 0, bytes.Length);
requestStream.Close();
HttpWebResponse response;
response = (HttpWebResponse)request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK)
{
Stream responseStream = response.GetResponseStream();
string responseStr = new StreamReader(responseStream).ReadToEnd();
return responseStr;
}
return null;
}
In your specific situation:
Instead of:
request.ContentType = "application/x-www-form-urlencoded";
use:
request.ContentType = "text/xml; encoding='utf-8'";
Also, remove:
string postData = "XMLData=" + Sendingxml;
And replace:
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
with:
byte[] byteArray = Encoding.UTF8.GetBytes(Sendingxml.ToString());
All the answers here suggest to use ipairs but beware, it does not work all the time.
t = {[2] = 44, [4]=77, [6]=88}
--This for loop prints the table
for key,value in next,t,nil do
print(key,value)
end
--This one does not print the table
for key,value in ipairs(t) do
print(key,value)
end
An activity populates the ActionBar in its onCreateOptionsMenu()
method.
Instead of using setcustomview()
, just override onCreateOptionsMenu
like this:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mainmenu, menu);
return true;
}
If an actions in the ActionBar is selected, the onOptionsItemSelected()
method is called. It receives the selected action as parameter. Based on this information you code can decide what to do for example:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menuitem1:
Toast.makeText(this, "Menu Item 1 selected", Toast.LENGTH_SHORT).show();
break;
case R.id.menuitem2:
Toast.makeText(this, "Menu item 2 selected", Toast.LENGTH_SHORT).show();
break;
}
return true;
}
You can't find RMSE function directly in SKLearn. But , instead of manually doing sqrt , there is another standard way using sklearn. Apparently, Sklearn's mean_squared_error itself contains a parameter called as "squared" with default value as true .If we set it to false ,the same function will return RMSE instead of MSE.
# code changes implemented by Esha Prakash
from sklearn.metrics import mean_squared_error
rmse = mean_squared_error(y_true, y_pred , squared=False)
Easiest way to use this function is to start by 'Recording a Macro'. Once you start recording, save the file to the location you want, with the name you want, and then of course set the file type, most likely 'Excel Macro Enabled Workbook' ~ 'XLSM'
Stop recording and you can start inspecting your code.
I wrote the code below which allows you to save a workbook using the path where the file was originally located, naming it as "Event [date in cell "A1"]"
Option Explicit
Sub SaveFile()
Dim fdate As Date
Dim fname As String
Dim path As String
fdate = Range("A1").Value
path = Application.ActiveWorkbook.path
If fdate > 0 Then
fname = "Event " & fdate
Application.ActiveWorkbook.SaveAs Filename:=path & "\" & fname, _
FileFormat:=xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False
Else
MsgBox "Chose a date for the event", vbOKOnly
End If
End Sub
Copy the code into a new module and then write a date in cell "A1" e.g. 01-01-2016 -> assign the sub to a button and run. [Note] you need to make a save file before this script will work, because a new workbook is saved to the default autosave location!
Try:
$result = curl_exec($cURL);
$result = json_decode($result,true);
Now you can access MessageID
from $result['MessageID']
.
As for the database, it's simply using a query like so:
INSERT INTO `tableName`(`Cancelled`,`Queued`,`SMSError`,`SMSIncommingMessage`,`Sent`,`SentDateTime`) VALUES('?','?','?','?','?');
Prepared.
My solution, to only hide the navigation bar, is:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final View decorView = getWindow().getDecorView();
decorView.setOnSystemUiVisibilityChangeListener (new View.OnSystemUiVisibilityChangeListener() {
@Override
public void onSystemUiVisibilityChange(int visibility) {
if ((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0) {
decorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
}
});
}
@Override
protected void onResume() {
super.onResume();
final int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION;
final View decorView = getWindow().getDecorView();
decorView.setSystemUiVisibility(uiOptions);
}
Here is the swift version (by using @Nitesh Borad objective C code) :-
if let img: UIImage = UIImage(data: previewImg[indexPath.row]) {
cell.cardPreview.image = img
} else {
// The image isn't cached, download the img data
// We should perform this in a background thread
let imgURL = NSURL(string: "webLink URL")
let request: NSURLRequest = NSURLRequest(URL: imgURL!)
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
let error = error
let data = data
if error == nil {
// Convert the downloaded data in to a UIImage object
let image = UIImage(data: data!)
// Store the image in to our cache
self.previewImg[indexPath.row] = data!
// Update the cell
dispatch_async(dispatch_get_main_queue(), {
if let cell: YourTableViewCell = tableView.cellForRowAtIndexPath(indexPath) as? YourTableViewCell {
cell.cardPreview.image = image
}
})
} else {
cell.cardPreview.image = UIImage(named: "defaultImage")
}
})
task.resume()
}
One of most upleasing functional forEach
's limitations is lack of checked exceptions support.
One possible workaround is to replace terminal forEach
with plain old foreach loop:
Stream<String> stream = Stream.of("", "1", "2", "3").filter(s -> !s.isEmpty());
Iterable<String> iterable = stream::iterator;
for (String s : iterable) {
fileWriter.append(s);
}
Here is list of most popular questions with other workarounds on checked exception handling within lambdas and streams:
Java 8 Lambda function that throws exception?
Java 8: Lambda-Streams, Filter by Method with Exception
How can I throw CHECKED exceptions from inside Java 8 streams?
Java 8: Mandatory checked exceptions handling in lambda expressions. Why mandatory, not optional?
Worked a day for this project. It maybe useful for u. I compressed and combined both Network and GPS. Plug and play directly in MainActivity.java (There are some DIY function for display result)

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 ?
The main reason you use the default queue over the main queue is to run tasks in the background.
For instance, if I am downloading a file from the internet and I want to update the user on the progress of the download, I will run the download in the priority default queue and update the UI in the main queue asynchronously.
dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){
//Background Thread
dispatch_async(dispatch_get_main_queue(), ^(void){
//Run UI Updates
});
});
A cleaner way to do this:
class Book {
public Title: string;
public Price: number;
public Description: string;
constructor(public BookId: number, public Author: string){}
}
Then
var bks: Book[] = [
new Book(1, "vamsee")
];
I wouldn't use a List in the first places as an EnumSet is more approriate but you can do
List<Something> somethingList = Arrays.asList(Something.values());
or
List<Something> somethingList =
new ArrayList<Something>(EnumSet.allOf(Something.class));
I think that you forget the
addAction(int icon, CharSequence title, PendingIntent intent)
Look here: Add Action
Change SUM(billableDuration) AS NumSecondsDelivered
to
sum(cast(billableDuration as bigint))
or
sum(cast(billableDuration as numeric(12, 0)))
according to your need.
The resultant type of of Sum expression is the same as the data type used. It throws error at time of overflow. So casting the column to larger capacity data type and then using Sum operation works fine.
Creating a tableview using tableViewController .
import UIKit
class TableViewController: UITableViewController
{
let tableViewModel = TableViewModel()
var product: [String] = []
var price: [String] = []
override func viewDidLoad()
{
super.viewDidLoad()
self.tableView.contentInset = UIEdgeInsetsMake( 20, 20 , 0, 0)
let priceProductDetails = tableViewModel.dataProvider()
for (key, value) in priceProductDetails
{
product.append(key)
price.append(value)
}
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return product.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
let cell = UITableViewCell(style: .Value1, reuseIdentifier: "UITableViewCell")
cell.textLabel?.text = product[indexPath.row]
cell.detailTextLabel?.text = price[indexPath.row]
return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)
{
print("You tapped cell number \(indexPath.row).")
}
}
You can make a function:
public void playNotificationSound()
{
try
{
Uri alarmSound = `Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + MyApplication.getInstance().getApplicationContext().getPackageName() + "/raw/notification");`
Ringtone r = RingtoneManager.getRingtone(MyApplication.getInstance().getApplicationContext(), alarmSound);
r.play();
}
catch (Exception e)
{
e.printStackTrace();
}
}
Call this function when you receive notification.
Here raw is the folder in res and the notification is the sound file in raw folder.
You can try following sample http://jsfiddle.net/xKJB8/3/
<img id="preview" src="http://www.gravatar.com/avatar/0e39d18b89822d1d9871e0d1bc839d06?s=128&d=identicon&r=PG">
<canvas id="myCanvas" />
var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
var img = document.getElementById("preview");
ctx.drawImage(img, 10, 10);
alert(c.toDataURL());
You can use background-size: cover;
Broadcast receiver code to check internet connectivity change:
public class BroadCastDetecter extends BroadcastReceiver {
public static boolean internet_status = false;
public static void checkInternetConenction(Context context) {
internet_status = false;
ConnectivityManager check = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (check != null) {
NetworkInfo[] info = check.getAllNetworkInfo();
if (info != null)
for (int i = 0; i < info.length; i++)
{
if (info[i].getState() == NetworkInfo.State.CONNECTED) {
internet_status = true;
}
}
if(internet_status)
{
//do what you want to if internet connection is available
}
}
}
@Override
public void onReceive(Context context, Intent intent)
{
try {
checkInternetConenction(context);
}catch(Exception e){
}
}
}
add this in manifest file:
<receiver android:name=".BroadCastDetecter">
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
</intent-filter>
</receiver>
For a popup javascript is required. Put this in your header:
<script>
function myFunction()
{
alert("I am an alert box!"); // this is the message in ""
}
</script>
And this in your body:
<input type="button" onclick="myFunction()" value="Show alert box">
When the button is pressed a box pops up with the message set in the header.
This can be put in any html or php file without the php tags.
-----EDIT-----
To display it using php try this:
<?php echo '<script>myfunction()</script>'; ?>
It may not be 100% correct but the principle is the same.
To display different messages you can either create lots of functions or you can pass a variable in to the function when you call it.
In your MainActivity, under onCreate:
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
And in your fragment activity under onResume
:
getActivity().setTitle(R.string.app_name_science);
Optional:- if they show warning of null reference
Objects.requireNonNull(getSupportActionBar()).setDisplayHomeAsUpEnabled(true);
Objects.requireNonNull(getActivity()).setTitle(R.string.app_name_science);
char grid[row][col];
memset(grid, ' ', sizeof(grid));
That's for initializing char array elements to space characters.
If by any chance you landed on this thread and wondering why adapter.invaidate()
or adapter.clear()
methods are not present in your case then maybe because you might be using RecyclerView.Adapter
instead of BaseAdapter
which is used by the asker of this question. If clearing the list
or arraylist
not resolving your problem then it may happen that you are making two or more instances of the adapter
for ex.:
MainActivity
...
adapter = new CustomAdapter(list);
adapter.notifyDataSetChanged();
recyclerView.setAdapter(adapter);
...
and
SomeFragment
...
adapter = new CustomAdapter(newList);
adapter.notifyDataSetChanged();
...
If in the second case you are expecting a change in the list of inflated views in recycler view then it is not gonna happen as in the second time a new instance of the adapter
is created which is not attached to the recycler view. Setting notifyDataSetChanged
in the second adapter is not gonna change the content of recycer view. For that make a new instance of the recycler view in SomeFragment and attach it to the new instance of the adapter.
SomeFragment
...
recyclerView = new RecyclerView();
adapter = new CustomAdapter();
recyclerView.setAdapter(adapter);
...
Although, I don't recommend making multiple instances of the same adapter and recycler view.
by default <UL/>
contains default padding
therefore try adding style to padding:0px
in css class or inline css
This is a working Java version of the example you gave :
void waitForLoad(WebDriver driver) {
new WebDriverWait(driver, 30).until((ExpectedCondition<Boolean>) wd ->
((JavascriptExecutor) wd).executeScript("return document.readyState").equals("complete"));
}
Example For c#:
public static void WaitForLoad(IWebDriver driver, int timeoutSec = 15)
{
IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
WebDriverWait wait = new WebDriverWait(driver, new TimeSpan(0, 0, timeoutSec));
wait.Until(wd => js.ExecuteScript("return document.readyState").ToString() == "complete");
}
Example for PHP:
final public function waitUntilDomReadyState(RemoteWebDriver $webDriver): void
{
$webDriver->wait()->until(function () {
return $webDriver->executeScript('return document.readyState') === 'complete';
});
}
There are two ways of closing an alert dialog.
Option 1:
AlertDialog#create().dismiss();
Option 2:
The DialogInterface#dismiss();
Out of the box, the framework calls DialogInterface#dismiss();
when you define event listeners for the buttons:
AlertDialog#setNegativeButton();
AlertDialog#setPositiveButton();
AlertDialog#setNeutralButton();
for the Alert dialog.
Try rewriting your success handler to:
success : handleData
The success property of the ajax method only requires a reference to a function.
In your handleData function you can take up to 3 parameters:
object data
string textStatus
jqXHR jqXHR
Upgrade Automapper to version 6.2.2. It helped me
Please refer the below post. cmcculloh's answer worked for me. https://stackoverflow.com/posts/31683500/edit
As hinted at in the documentation, the easiest way to ensure that your tooltip does not wrap at all is to use
.tooltip-inner {
max-width: none;
white-space: nowrap;
}
With this, you don't have to worry about dimension values or anything like that. Main problem being if you have a super long line of text it will just go off of the screen (as you can see in the JSBin Example).
For those looking for a general strategy for reading and writing a string to file:
First, get a file object
You'll need the storage path. For the internal storage, use:
File path = context.getFilesDir();
For the external storage (SD card), use:
File path = context.getExternalFilesDir(null);
Then create your file object:
File file = new File(path, "my-file-name.txt");
Write a string to the file
FileOutputStream stream = new FileOutputStream(file);
try {
stream.write("text-to-write".getBytes());
} finally {
stream.close();
}
Or with Google Guava
String contents = Files.toString(file, StandardCharsets.UTF_8);
Read the file to a string
int length = (int) file.length();
byte[] bytes = new byte[length];
FileInputStream in = new FileInputStream(file);
try {
in.read(bytes);
} finally {
in.close();
}
String contents = new String(bytes);
Or if you are using Google Guava
String contents = Files.toString(file,"UTF-8");
For completeness I'll mention
String contents = new Scanner(file).useDelimiter("\\A").next();
which requires no libraries, but benchmarks 50% - 400% slower than the other options (in various tests on my Nexus 5).
Notes
For each of these strategies, you'll be asked to catch an IOException.
The default character encoding on Android is UTF-8.
If you are using external storage, you'll need to add to your manifest either:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
or
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
Write permission implies read permission, so you don't need both.
Edit:
As some folks needs help in Unlocking device after locking programmatically, I came through post Android screen lock/ unlock programatically, please have look, may help you.
Original Answer was:
You need to get Admin permission and you can lock phone screen
please check below simple tutorial to achive this one
Lock Phone Screen Programmtically
also here is the code example..
LockScreenActivity.java
public class LockScreenActivity extends Activity implements OnClickListener {
private Button lock;
private Button disable;
private Button enable;
static final int RESULT_ENABLE = 1;
DevicePolicyManager deviceManger;
ActivityManager activityManager;
ComponentName compName;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
deviceManger = (DevicePolicyManager)getSystemService(
Context.DEVICE_POLICY_SERVICE);
activityManager = (ActivityManager)getSystemService(
Context.ACTIVITY_SERVICE);
compName = new ComponentName(this, MyAdmin.class);
setContentView(R.layout.main);
lock =(Button)findViewById(R.id.lock);
lock.setOnClickListener(this);
disable = (Button)findViewById(R.id.btnDisable);
enable =(Button)findViewById(R.id.btnEnable);
disable.setOnClickListener(this);
enable.setOnClickListener(this);
}
@Override
public void onClick(View v) {
if(v == lock){
boolean active = deviceManger.isAdminActive(compName);
if (active) {
deviceManger.lockNow();
}
}
if(v == enable){
Intent intent = new Intent(DevicePolicyManager
.ACTION_ADD_DEVICE_ADMIN);
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN,
compName);
intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION,
"Additional text explaining why this needs to be added.");
startActivityForResult(intent, RESULT_ENABLE);
}
if(v == disable){
deviceManger.removeActiveAdmin(compName);
updateButtonStates();
}
}
private void updateButtonStates() {
boolean active = deviceManger.isAdminActive(compName);
if (active) {
enable.setEnabled(false);
disable.setEnabled(true);
} else {
enable.setEnabled(true);
disable.setEnabled(false);
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case RESULT_ENABLE:
if (resultCode == Activity.RESULT_OK) {
Log.i("DeviceAdminSample", "Admin enabled!");
} else {
Log.i("DeviceAdminSample", "Admin enable FAILED!");
}
return;
}
super.onActivityResult(requestCode, resultCode, data);
}
}
MyAdmin.java
public class MyAdmin extends DeviceAdminReceiver{
static SharedPreferences getSamplePreferences(Context context) {
return context.getSharedPreferences(
DeviceAdminReceiver.class.getName(), 0);
}
static String PREF_PASSWORD_QUALITY = "password_quality";
static String PREF_PASSWORD_LENGTH = "password_length";
static String PREF_MAX_FAILED_PW = "max_failed_pw";
void showToast(Context context, CharSequence msg) {
Toast.makeText(context, msg, Toast.LENGTH_SHORT).show();
}
@Override
public void onEnabled(Context context, Intent intent) {
showToast(context, "Sample Device Admin: enabled");
}
@Override
public CharSequence onDisableRequested(Context context, Intent intent) {
return "This is an optional message to warn the user about disabling.";
}
@Override
public void onDisabled(Context context, Intent intent) {
showToast(context, "Sample Device Admin: disabled");
}
@Override
public void onPasswordChanged(Context context, Intent intent) {
showToast(context, "Sample Device Admin: pw changed");
}
@Override
public void onPasswordFailed(Context context, Intent intent) {
showToast(context, "Sample Device Admin: pw failed");
}
@Override
public void onPasswordSucceeded(Context context, Intent intent) {
showToast(context, "Sample Device Admin: pw succeeded");
}
}
This solved my problem: Kotlin Code:
val fragmentTransaction = activity.supportFragmentManager.beginTransaction()
fragmentTransaction.add(dialogFragment, tag)
fragmentTransaction.commitAllowingStateLoss()
How is commitAllowingStateLoss()
is different than commit()
?
As per documentation:
Like commit()
but allows the commit to be executed after an activity's state is saved.
https://developer.android.com/reference/android/app/FragmentTransaction#commitAllowingStateLoss()
P.S: you can show Fragment Dialogs or can load fragments by this method. Applicable for both.
You need to precede the lines starting with gcc
and rm
with a hard tab. Commands in make rules are required to start with a tab (unless they follow a semicolon on the same line).
The result should look like this:
PROG = semsearch
all: $(PROG)
%: %.c
gcc -o $@ $< -lpthread
clean:
rm $(PROG)
Note that some editors may be configured to insert a sequence of spaces instead of a hard tab. If there are spaces at the start of these lines you'll also see the "missing separator" error. If you do have problems inserting hard tabs, use the semicolon way:
PROG = semsearch
all: $(PROG)
%: %.c ; gcc -o $@ $< -lpthread
clean: ; rm $(PROG)
You also could set both parameters like,
mMap.moveCamera( CameraUpdateFactory.newLatLngZoom(new LatLng(21.000000, -101.400000) ,4) );
This locates your map on a specific position and zoom. I use this on the setting up my map.
Update: This answer is no longer available as Whatsapp had stopped exposing the phone number as account name, kindly disregard this answer.
=================================================================================
Its been almost 6 months and I believe I should update this with an alternative solution you might want to consider.
As of today, you can rely on another big application Whatsapp, using AccountManager. Millions of devices have this application installed and if you can't get the phone number via TelephonyManager, you may give this a shot.
Permission:
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
Code:
AccountManager am = AccountManager.get(this);
Account[] accounts = am.getAccounts();
ArrayList<String> googleAccounts = new ArrayList<String>();
for (Account ac : accounts) {
String acname = ac.name;
String actype = ac.type;
// Take your time to look at all available accounts
System.out.println("Accounts : " + acname + ", " + actype);
}
Check actype for whatsapp account
if(actype.equals("com.whatsapp")){
String phoneNumber = ac.name;
}
Of course you may not get it if user did not install Whatsapp, but its worth to try anyway. And remember you should always ask user for confirmation.

Here's how I do it, the keys are getItemViewType and getViewTypeCount in the Adapter
class. getViewTypeCount
returns how many types of items we have in the list, in this case we have a header item and an event item, so two. getItemViewType
should return what type of View
we have at the input position
.
Android will then take care of passing you the right type of View
in convertView
automatically.
Here what the result of the code below looks like:
First we have an interface that our two list item types will implement
public interface Item {
public int getViewType();
public View getView(LayoutInflater inflater, View convertView);
}
Then we have an adapter that takes a list of Item
public class TwoTextArrayAdapter extends ArrayAdapter<Item> {
private LayoutInflater mInflater;
public enum RowType {
LIST_ITEM, HEADER_ITEM
}
public TwoTextArrayAdapter(Context context, List<Item> items) {
super(context, 0, items);
mInflater = LayoutInflater.from(context);
}
@Override
public int getViewTypeCount() {
return RowType.values().length;
}
@Override
public int getItemViewType(int position) {
return getItem(position).getViewType();
}
@Override public View getView(int position, View convertView, ViewGroup parent) { return getItem(position).getView(mInflater, convertView); }
EDIT Better For Performance.. can be noticed when scrolling
private static final int TYPE_ITEM = 0;
private static final int TYPE_SEPARATOR = 1;
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
int rowType = getItemViewType(position);
View View;
if (convertView == null) {
holder = new ViewHolder();
switch (rowType) {
case TYPE_ITEM:
convertView = mInflater.inflate(R.layout.task_details_row, null);
holder.View=getItem(position).getView(mInflater, convertView);
break;
case TYPE_SEPARATOR:
convertView = mInflater.inflate(R.layout.task_detail_header, null);
holder.View=getItem(position).getView(mInflater, convertView);
break;
}
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
return convertView;
}
public static class ViewHolder {
public View View; }
}
Then we have classes the implement Item
and inflate the correct layouts. In your case you'll have something like a Header
class and a ListItem
class.
public class Header implements Item {
private final String name;
public Header(String name) {
this.name = name;
}
@Override
public int getViewType() {
return RowType.HEADER_ITEM.ordinal();
}
@Override
public View getView(LayoutInflater inflater, View convertView) {
View view;
if (convertView == null) {
view = (View) inflater.inflate(R.layout.header, null);
// Do some initialization
} else {
view = convertView;
}
TextView text = (TextView) view.findViewById(R.id.separator);
text.setText(name);
return view;
}
}
And then the ListItem
class
public class ListItem implements Item {
private final String str1;
private final String str2;
public ListItem(String text1, String text2) {
this.str1 = text1;
this.str2 = text2;
}
@Override
public int getViewType() {
return RowType.LIST_ITEM.ordinal();
}
@Override
public View getView(LayoutInflater inflater, View convertView) {
View view;
if (convertView == null) {
view = (View) inflater.inflate(R.layout.my_list_item, null);
// Do some initialization
} else {
view = convertView;
}
TextView text1 = (TextView) view.findViewById(R.id.list_content1);
TextView text2 = (TextView) view.findViewById(R.id.list_content2);
text1.setText(str1);
text2.setText(str2);
return view;
}
}
And a simple Activity
to display it
public class MainActivity extends ListActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
List<Item> items = new ArrayList<Item>();
items.add(new Header("Header 1"));
items.add(new ListItem("Text 1", "Rabble rabble"));
items.add(new ListItem("Text 2", "Rabble rabble"));
items.add(new ListItem("Text 3", "Rabble rabble"));
items.add(new ListItem("Text 4", "Rabble rabble"));
items.add(new Header("Header 2"));
items.add(new ListItem("Text 5", "Rabble rabble"));
items.add(new ListItem("Text 6", "Rabble rabble"));
items.add(new ListItem("Text 7", "Rabble rabble"));
items.add(new ListItem("Text 8", "Rabble rabble"));
TwoTextArrayAdapter adapter = new TwoTextArrayAdapter(this, items);
setListAdapter(adapter);
}
}

You can also get fancier and use ViewHolders
, load stuff asynchronously, or whatever you like.
I use something like this (you should add code to deal with the various fails):
var response = RunTaskWithTimeout<ReturnType>(
(Func<ReturnType>)delegate { return SomeMethod(someInput); }, 30);
/// <summary>
/// Generic method to run a task on a background thread with a specific timeout, if the task fails,
/// notifies a user
/// </summary>
/// <typeparam name="T">Return type of function</typeparam>
/// <param name="TaskAction">Function delegate for task to perform</param>
/// <param name="TimeoutSeconds">Time to allow before task times out</param>
/// <returns></returns>
private T RunTaskWithTimeout<T>(Func<T> TaskAction, int TimeoutSeconds)
{
Task<T> backgroundTask;
try
{
backgroundTask = Task.Factory.StartNew(TaskAction);
backgroundTask.Wait(new TimeSpan(0, 0, TimeoutSeconds));
}
catch (AggregateException ex)
{
// task failed
var failMessage = ex.Flatten().InnerException.Message);
return default(T);
}
catch (Exception ex)
{
// task failed
var failMessage = ex.Message;
return default(T);
}
if (!backgroundTask.IsCompleted)
{
// task timed out
return default(T);
}
// task succeeded
return backgroundTask.Result;
}
If your requirements are to have no duplicates, you should be using a HashSet.
HashSet.Add will return false when the item already exists (if that even matters to you).
You can use the constructor that @pstrjds links to below (or here) to define the equality operator or you'll need to implement the equality methods in RemoteDevice
(GetHashCode
& Equals
).
Beginning with API level 3 you can use onUserInteraction() on an Activity with a boolean to determine if the user is interacting with the device.
http://developer.android.com/reference/android/app/Activity.html#onUserInteraction()
@Override
public void onUserInteraction() {
super.onUserInteraction();
userIsInteracting = true;
}
As a field on the Activity I have:
private boolean userIsInteracting;
Finally, my spinner:
mSpinnerView.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View view, int position, long arg3) {
spinnerAdapter.setmPreviousSelectedIndex(position);
if (userIsInteracting) {
updateGUI();
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
As you come and go through the activity the boolean is reset to false. Works like a charm.
add below code to activity_main.xml file:
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="buttonClick"
android:text="@string/button" />
and just add the below method to the MainActivity.java file:
public void buttonClick(View view){
Intent i = new Intent(getApplicationContext()SendPhotos.class);
startActivity(i);
}
Your application is not able to connect to activemq. Check that your activemq is running and listening on localhost 61616.
You can try using: netstat -a
to check if the activemq process has started. Or try check if you can access your actvemq using admin page: localhost:8161/admin/queues.jsp
On mac you will start your activemq using:
$ACTMQ_HOME/bin/activemq start
Or if your config file (activemq.xml ) if located in another location you can use:
$ACTMQ_HOME/bin/activemq start xbean:file:${location_of_your_config_file}
In your case the executable is under: bin/macosx/activemq
so you need to use: $ACTMQ_HOME/bin/macosx/activemq start
Create Arraylist<Date>
of Date class. And use Collections.sort()
for ascending order.
Sorts the specified list into ascending order, according to the natural ordering of its elements.
For Sort it in descending order See Collections.reverseOrder()
Collections.sort(yourList, Collections.reverseOrder());
I know this is an old thread, but it exactly matches what recently happened to me and I thought I'd document it here. The setup (in Docker) is as follows:
The symptom was a "502 Gateway Timeout" on the application login prompt. Examination of logs found:
POST
to /login
... and so .../login
request, and eventually reported a timeout.499
response, which of course means "the host died."/login
request did not appear at all(!) in the FPM server's logs!It turned out that the problem was a failure to connect to the database to verify the login. But how to figure that out turned out to be pure guesswork.
The complete absence of application traceback logs ... or even a record that the request had been received by FPM ... was a complete (and, devastating ...) surprise to me. Yes, the application is supposed to log failures, but in this case it looks like the FPM worker process died with a runtime error, leading to the 499
response from nginx. Now, this obviously is a problem in our application ... somewhere. But I wanted to record the particulars of what happened for the benefit of the next folks who face something like this.
Those who getting the version issue try this code ..
public static void switchLocal(Context context, String lcode, Activity activity) {
if (lcode.equalsIgnoreCase(""))
return;
Resources resources = context.getResources();
Locale locale = new Locale(lcode);
Locale.setDefault(locale);
android.content.res.Configuration config = new
android.content.res.Configuration();
config.locale = locale;
resources.updateConfiguration(config, resources.getDisplayMetrics());
//restart base activity
activity.finish();
activity.startActivity(activity.getIntent());
}
alert("Selected value is: "+$(".leaderMultiSelctdropdown").select2("val"));
alternatively, if you used a regular selectbox as base, you should be able to use the normal jquery call, too:
alert("Selected value is: "+$(".leaderMultiSelctdropdown").val());
both return an array of the selected keys.
There is a trick for this. All you have to do is to use RelativeLayout
instead of LinearLayout
as the main container. It's important to have android:layout_gravity="fill_horizontal"
set for it. That should do it.
Slightly faster version of the implementation (If you know that most couples lists will have different lengths):
def checkEqual(L1, L2):
return len(L1) == len(L2) and sorted(L1) == sorted(L2)
Comparing:
>>> timeit(lambda: sorting([1,2,3], [3,2,1]))
2.42745304107666
>>> timeit(lambda: lensorting([1,2,3], [3,2,1]))
2.5644469261169434 # speed down not much (for large lists the difference tends to 0)
>>> timeit(lambda: sorting([1,2,3], [3,2,1,0]))
2.4570400714874268
>>> timeit(lambda: lensorting([1,2,3], [3,2,1,0]))
0.9596951007843018 # speed up
I have just been in a similar position with regards to setting the 777 permissions on the apache website hosting directory. After a little bit of tinkering it seems that changing the group ownership of the folder to the "apache" group allowed access to the folder based on the user group.
1) make sure that the group ownership of the folder is set to the group apache used / generates for use. (check /etc/groups, mine was www-data on Ubuntu)
2) set the folder permissions to 774 to stop "everyone" from having any change access, but allowing the owner and group permissions required.
3) add your user account to the group that has permission on the folder (mine was www-data).
Just an improvement to the nice answer given by @vuhung3990. I implemented the solution and works great but if I touch one radio button it will be selected and nothing happens.
I suggest to also change page when a radio button is tapped. To do this, simply add a listener to the radioGroup:
mPager = (ViewPager) findViewById(R.id.pager);
final RadioGroup radioGroup = (RadioGroup)findViewById(R.id.radiogroup);
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
switch (checkedId) {
case R.id.radioButton :
mPager.setCurrentItem(0, true);
break;
case R.id.radioButton2 :
mPager.setCurrentItem(1, true);
break;
case R.id.radioButton3 :
mPager.setCurrentItem(2, true);
break;
}
}
});
I had a similar problem using android 5.0 with a bad parent activity name
<activity
android:name=".DisplayMessageActivity"
android:label="@string/title_activity_display_message"
android:parentActivityName=".MainActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.myfirstapp.MainActivity" />
</activity>
I removed the com.example.myfirstapp from the parent activity name and it worked properly
Change this dialog.cancel();
to dialog.dismiss();
The solution is to call dismiss()
on the Dialog
you created in NetErrorPage.java:114 before exiting the Activity
, e.g. in onPause()
.
Views have a reference to their parent Context
(taken from constructor argument). If you leave an Activity
without destroying Dialog
s and other dynamically created View
s, they still hold this reference to your Activity
(if you created with this as Context
: like new ProgressDialog(this)
), so it cannot be collected by the GC, causing a memory leak.
You need to add:
#include <string>
In your header file.
This is the best possible way that I have tried out. If it should help anyone...
+ (UIViewController*) topMostController
{
UIViewController *topController = [UIApplication sharedApplication].keyWindow.rootViewController;
while (topController.presentedViewController) {
topController = topController.presentedViewController;
}
return topController;
}
If you are using Bootstrap 4, and you don't want to change your markup:
var $myGroup = $('#myGroup');
$myGroup.on('show.bs.collapse','.collapse', function() {
$myGroup.find('.collapse.show').collapse('hide');
});
add the lines in your /res/values.xml file in resource root tab like this:
<resources
xmlns:tools="http://schemas.android.com/tools"
tools:locale="en" tools:ignore="MissingTranslation">
tools:locale set the local language to English, no need of language translation later on that for all resource strings and tools:ignore let Lint to isnore the missing translations of the resource string values.
Not all parameters are supported by all cameras - actually, they are one of the most troublesome part of the OpenCV library. Each camera type - from android cameras to USB cameras to professional ones offer a different interface to modify its parameters. There are many branches in OpenCV code to support as many of them, but of course not all possibilities are covered.
What you can do is to investigate your camera driver, write a patch for OpenCV and send it to code.opencv.org. This way others will enjoy your work, the same way you enjoy others'.
There is also a possibility that your camera does not support your request - most USB cams are cheap and simple. Maybe that parameter is just not available for modifications.
If you are sure the camera supports a given param (you say the camera manufacturer provides some code) and do not want to mess with OpenCV, you can wrap that sample code in C++ with boost::python, to make it available in Python. Then, enjoy using it.
As others have mentioned the Lint warning is because of the potential memory leak. You can avoid the Lint warning by passing a Handler.Callback
when constructing Handler
(i.e. you don't subclass Handler
and there is no Handler
non-static inner class):
Handler mIncomingHandler = new Handler(new Handler.Callback() {
@Override
public boolean handleMessage(Message msg) {
// todo
return true;
}
});
As I understand it, this will not avoid the potential memory leak. Message
objects hold a reference to the mIncomingHandler
object which holds a reference the Handler.Callback
object which holds a reference to the Service
object. As long as there are messages in the Looper
message queue, the Service
will not be GC. However, it won't be a serious issue unless you have long delay messages in the message queue.
I had this error too, my problem was in some part of code I didn't close file descriptor and in other part, I tried to open that file!!
use close(fd)
system call after you finished working on a file.
I use the actionBarSherlock,
after we set supportActionBar.setHomeButtonEnabled(true);
we can override the onMenuItemSelected method:
@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
int itemId = item.getItemId();
switch (itemId) {
case android.R.id.home:
toggle();
// Toast.makeText(this, "home pressed", Toast.LENGTH_LONG).show();
break;
}
return true;
}
I hope this work for you ~~~ good luck
If you don't require support for IE6:
h1 {margin-bottom:20px;}
div + div {margin-top:10px;}
The second line adds spacing between divs, but will not add any before the first div or after the last one.
If you are using a WAMP server then try this:
Single click on the WAMP server icon at the taskbar
Select the option put online
Your server will restart automatically
Then try to access your localwebsite
moment.js
is great but sometimes you don't want to pull a large number of dependencies for simple things.
The following works as well:
var tzoffset = (new Date()).getTimezoneOffset() * 60000; //offset in milliseconds
var localISOTime = (new Date(Date.now() - tzoffset)).toISOString().slice(0, -1);
// => '2015-01-26T06:40:36.181'
The slice(0, -1)
gets rid of the trailing Z
which represents Zulu timezone and can be replaced by your own.
When set the new value of element, you need call trigger change.
$('element').val(newValue).trigger('change');
MyLocation is a Swift iOS Demo.
You can use this demo for the following:
Show the current location.
Choose other location: in this case stop tracking the location.
Add a push pin to a MKMapView(iOS) when touching.
In addition to the POSIX conformant syntax used in this answer,
basename string [suffix]
as in
basename /foo/fizzbuzz.bar .bar
GNU basename
supports another syntax:
basename -s .bar /foo/fizzbuzz.bar
with the same result. The difference and advantage is that -s
implies -a
, which supports multiple arguments:
$ basename -s .bar /foo/fizzbuzz.bar /baz/foobar.bar
fizzbuzz
foobar
This can even be made filename-safe by separating the output with NUL bytes using the -z
option, for example for these files containing blanks, newlines and glob characters (quoted by ls
):
$ ls has*
'has'$'\n''newline.bar' 'has space.bar' 'has*.bar'
Reading into an array:
$ readarray -d $'\0' arr < <(basename -zs .bar has*)
$ declare -p arr
declare -a arr=([0]=$'has\nnewline' [1]="has space" [2]="has*")
readarray -d
requires Bash 4.4 or newer. For older versions, we have to loop:
while IFS= read -r -d '' fname; do arr+=("$fname"); done < <(basename -zs .bar has*)
@delato468 comment must be listed as a solution as it worked for me.
In addition to defining the parameter, the user must pass it too at the time of calling the function
fetch_data(PDO $pdo, $cat_id)
You should avoid using expensive methods. You don't need any column for TBL2.
SELECT COUNT(*) FROM(
SELECT TOP 1 1 AS CNT FROM TBL1
WHERE ColumnValue ='FooDoo') AS TBL2
Or this code:
IF EXISTS (SELECT TOP 1 1 FROM TABLE1 AS T1
WHERE T1.ColumnValue='VooDoo')
SELECT 1
ELSE
SELECT 0
Another option is git merge --squash <feature branch>
then finally do a git commit
.
From Git merge
--squash
--no-squash
Produce the working tree and index state as if a real merge happened (except for the merge information), but do not actually make a commit or move the
HEAD
, nor record$GIT_DIR/MERGE_HEAD
to cause the nextgit commit
command to create a merge commit. This allows you to create a single commit on top of the current branch whose effect is the same as merging another branch (or more in case of an octopus).
In Galaxy s6 - I resolved it by: Settings -> About device -> Software info -> Build number - tap it 7 times to enable Developer options. Go back to Settings -> Developer options -> turn on USB debugging.
Go back to your terminal adb devices
and you should see the connected device. Hope that helps.
below code might help you
var objControl=document.getElementById("divid");
objControl.scrollTop = objControl.offsetTop;
I was working with a list of toasts (alert messages), List<Alert>
from C# and needed it as JavaScript array for Toastr in a partial view (.cshtml
file). The JavaScript code below is what worked for me:
var toasts = @Html.Raw(Newtonsoft.Json.JsonConvert.SerializeObject(alerts));
toasts.forEach(function (entry) {
var command = entry.AlertStyle;
var message = entry.Message;
if (command === "danger") { command = "error"; }
toastr[command](message);
});
You need to install the package first.
npm install --save react-fontawesome
OR
npm i --save @fortawesome/react-fontawesome
Don't forget to use className
instead of class
.
Later on you need to import them in the file where you wanna use them.
import 'font-awesome/css/font-awesome.min.css'
or
import FontAwesomeIcon from '@fortawesome/react-fontawesome'
You're thinking too complicated. It's actually just $('#'+openaddress)
.
I prefer nth-child() to eq() as it uses 1-based indexing rather than 0-based, which is slightly easier on my brain.
//selects the 2nd option
$('select>option:nth-child(2)').attr('selected', true);
A query string carries textual data so there is no option but to explode the array, encode it correctly and pass it in a representational format of your choice:
p1=value1&pN=valueN...
data=[value1,...,valueN]
data={p1:value1,...,pN:valueN}
and then decode it in your server side code.
Then number of columns must match between both parts of the union.
In order to build the full path, you need to "aggregate" all values of the Location
column. You still need to select the id and other columns inside the CTE in order to be able to join properly. You get "rid" of them by simply not selecting them in the outer select:
with q as
(
select ID, PartOf_LOC_id, Location, ' > ' + Location as path
from tblLocation
where ID = 1
union all
select child.ID, child.PartOf_LOC_id, Location, parent.path + ' > ' + child.Location
from tblLocation child
join q parent on parent.ID = t.LOC_PartOf_ID
)
select path
from q;
Use files.exclude:
workspace settings
tabAdd this code to the settings.json
file displayed on the right side:
// Place your settings in this file to overwrite default and user settings.
{
"settings": {
"files.exclude": {
"**/.git": true, // this is a default value
"**/.DS_Store": true, // this is a default value
"**/node_modules": true, // this excludes all folders
// named "node_modules" from
// the explore tree
// alternative version
"node_modules": true // this excludes the folder
// only from the root of
// your workspace
}
}
}
If you chose File -> Preferences -> User Settings then you configure the exclude folders globally for your current user.
FOO=bar
export FOO
def nans(df): return df[df.isnull().any(axis=1)]
then when ever you need it you can type:
nans(your_dataframe)
You can always take the CTE, (Common Tabular Expression), approach.
;WITH updateCTE AS
(
SELECT ID, TITLE
FROM HOLD_TABLE
WHERE ID = 101
)
UPDATE updateCTE
SET TITLE = 'TEST';
In MySQL, the word 'type' is a Reserved Word.

Try this to get value from select element by Element Name
$("select[name=elementnamehere]").val();
For IE browsers, the "VBScript solution" works.
But as mentioned by @purefusion at Bypass Printdialog in IE9, Use Print() rather than window.print()

I got the same error in 1.10.2. In my case, I wanted to make clicking on the background overlay hide the currently visible dialog, regardless of which element it was based upon. Therefore I had this:
$('body').on("click", ".ui-widget-overlay", function () {
$(".ui-dialog").dialog('destroy');
});
This used to be working, so I think they must have removed support in JQUI for calling .dialog() on the popup itself at some point.
My workaround looks like this:
$('body').on("click", ".ui-widget-overlay", function () {
$('#' + $(".ui-dialog").attr('aria-describedby')).dialog('destroy');
});
If your tiles are not in your bundle, either copied from the bundle or downloaded from the internet you can get the directory like this
NSString *documentdir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *tileDirectory = [documentdir stringByAppendingPathComponent:@"xxxx/Tiles"];
NSLog(@"Tile Directory: %@", tileDirectory);
Here's a solution using a lineJoin to round the corners. Works if you just need a solid shape but not so much if you need a thin border that's smaller than the border radius.
function roundedRect(ctx, options) {
ctx.strokeStyle = options.color;
ctx.fillStyle = options.color;
ctx.lineJoin = "round";
ctx.lineWidth = options.radius;
ctx.strokeRect(
options.x+(options.radius*.5),
options.y+(options.radius*.5),
options.width-options.radius,
options.height-options.radius
);
ctx.fillRect(
options.x+(options.radius*.5),
options.y+(options.radius*.5),
options.width-options.radius,
options.height-options.radius
);
ctx.stroke();
ctx.fill();
}
const canvas = document.getElementsByTagName("CANVAS")[0];
let ctx = canvas.getContext('2d');
roundedRect(ctx, {
x: 10,
y: 10,
width: 200,
height: 100,
radius: 10,
color: "red"
});
A nice option is to use tar -tvvf <filePath>
which adds a line that reports the kind of file.

First you need to set a reference (Menu: Tools->References) to the Microsoft Excel Object Library then you can access all Excel Objects.
After you added the Reference you have full access to all Excel Objects. You need to add Excel in front of everything for example:
Dim xlApp as Excel.Application
Let's say you added an Excel Workbook Object in your Form and named it xLObject.
Here is how you Access a Sheet of this Object and change a Range
Dim sheet As Excel.Worksheet
Set sheet = xlObject.Object.Sheets(1)
sheet.Range("A1") = "Hello World"
(I copied the above from my answer to this question)
Another way to use Excel in Access is to start Excel through a Access Module (the way shahkalpesh described it in his answer)
Thanks Radu Adrian Moldovan for the suggestion.
Here is an implementation using queue:
private static List<String> listAllFilePath(Path hdfsFilePath, FileSystem fs)
throws FileNotFoundException, IOException {
List<String> filePathList = new ArrayList<String>();
Queue<Path> fileQueue = new LinkedList<Path>();
fileQueue.add(hdfsFilePath);
while (!fileQueue.isEmpty()) {
Path filePath = fileQueue.remove();
if (fs.isFile(filePath)) {
filePathList.add(filePath.toString());
} else {
FileStatus[] fileStatus = fs.listStatus(filePath);
for (FileStatus fileStat : fileStatus) {
fileQueue.add(fileStat.getPath());
}
}
}
return filePathList;
}
The website was running fine then suddenly it started to display this same error 404 message (The origin server did not find a current representation for the target resource or is not willing to disclose that one exists), Perhaps because of switching servers back and forward from Tomcat 9 to 8 and 7
In my case, i only had to update the project which was causing this error then restart the specific tomcat version. You may also need to Maven Clean and Maven Install after the "Maven Update Project"
If you not have configured a billing account with your credit card, the API do not work. The Google is now very hungry for money and not open more your products "free". Obviously that him offer a free limited access number of consults and over this acces, the billing is very high.
If you create a user using a profile like this:
CREATE PROFILE my_profile LIMIT
PASSWORD_LIFE_TIME 30;
ALTER USER scott PROFILE my_profile;
then you can change the password lifetime like this:
ALTER PROFILE my_profile LIMIT
PASSWORD_LIFE_TIME UNLIMITED;
I hope that helps.

}
function getPxInt(pxValue) {
return parseInt(pxValue.trim("px"))
}
function isIPhone(){
return (
(navigator.platform.indexOf("iPhone") != -1) ||
(navigator.platform.indexOf("iPod") != -1)
);
}
and then use such as
$("#banner-img").change(function () {
var reader = new FileReader();
getOrientation(this.files[0], function(orientation) {
rotate($('#banner-img-preview'), orientation, 1)
});
reader.onload = function (e) {
$('#banner-img-preview').attr('src', e.target.result)
$('#banner-img-preview').css('display', 'inherit')
};
// read the image file as a data URL.
reader.readAsDataURL(this.files[0]);
});
Interestingly, if you have a frame, image, or form named 'location', then 'document.location' provides a reference to the frame window, image, or form, respectively, instead of the Location object. Apparently, this is because the document.forms, document.images, and window.frames collection name lookup gets priority over the mapping to window.location.
<img name='location' src='location.png'>
if (document.location.tagName == 'IMG') alert('Hello!')
In addition to @Elltz answer, we can use both fill and image for background:
someNode.setBackground(
new Background(
Collections.singletonList(new BackgroundFill(
Color.WHITE,
new CornerRadii(500),
new Insets(10))),
Collections.singletonList(new BackgroundImage(
new Image("image/logo.png", 100, 100, false, true),
BackgroundRepeat.NO_REPEAT,
BackgroundRepeat.NO_REPEAT,
BackgroundPosition.CENTER,
BackgroundSize.DEFAULT))));
Use
setBackground(
new Background(
Collections.singletonList(new BackgroundFill(
Color.WHITE,
new CornerRadii(0),
new Insets(0))),
Collections.singletonList(new BackgroundImage(
new Image("file:clouds.jpg", 100, 100, false, true),
BackgroundRepeat.NO_REPEAT,
BackgroundRepeat.NO_REPEAT,
BackgroundPosition.DEFAULT,
new BackgroundSize(1.0, 1.0, true, true, false, false)
))));
(different last argument) to make the image full-window size.
I had the same problem when writing layout file, after I deleted these two lines:
android:layout_marginLeft="@dimen/activity_horizontal_margin"
android:layout_marginRight="@dimen/activity_horizontal_margin"
the errors were gone.
<?php
$connection = mysqli_connect("localhost","root","","php_sample_login_register");
if ($connection){
echo "DB is Connected <br>";
$sql = "CREATE TABLE user(
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(255)NOT NULL,
email VARCHAR(255)NOT NULL,
password VARCHAR(255) NOT NULL
);";
if(mysqli_query($connection,$sql)) {
echo "Created user table";
} else{
echo "User table already exists";
}
} else {
echo "error : DB isnot connected";
} ?>
Ultimately no. You can query for listings with a search string from an RSS feed such as this:

I too faced the same problem, and I did a "Factory data reset", and it worked fine after that.
Perhaps bool is a tad "lighter" than Boolean; Interestingly, changing this:
namespace DuckbillServerWebAPI.Models
{
public class Expense
{
. . .
public bool CanUseOnItems { get; set; }
}
}
...to this:
namespace DuckbillServerWebAPI.Models
{
public class Expense
{
. . .
public Boolean CanUseOnItems { get; set; }
}
}
...caused my cs file to sprout a "using System;" Changing the type back to "bool" caused the using clause's hair to turn grey.
(Visual Studio 2010, WebAPI project)
Visual Studio Code shows a link at the top of a Go test file which lets you run all the tests in just that file.
In the "Output" window, you can see that it automatically generates a regex which contains all of the test names in the current file:
Running tool: C:\Go\bin\go.exe test -timeout 30s -run ^(TestFoo|TestBar|TestBaz)$ rootpackage\mypackage
Note: the very first time you open a Go file in VS Code it automatically offers to install some Go extensions for you. I assume the above requires that you have previously accepted the offer to install.
Check out yowsup
https://github.com/tgalal/yowsup
Yowsup is a python library that allows you to do all the previous in your own app. Yowsup allows you to login and use the Whatsapp service and provides you with all capabilities of an official Whatsapp client, allowing you to create a full-fledged custom Whatsapp client.
A solid example of Yowsup's usage is Wazapp. Wazapp is full featured Whatsapp client that is being used by hundreds of thousands of people around the world. Yowsup is born out of the Wazapp project. Before becoming a separate project, it was only the engine powering Wazapp. Now that it matured enough, it was separated into a separate project, allowing anyone to build their own Whatsapp client on top of it. Having such a popular client as Wazapp, built on Yowsup, helped bring the project into a much advanced, stable and mature level, and ensures its continuous development and maintaince.
Yowsup also comes with a cross platform command-line frontend called yowsup-cli. yowsup-cli allows you to jump into connecting and using Whatsapp service directly from command line.
One way to live-stream a RTSP-based webcam to a HTML5 client (involves re-encoding, so expect quality loss and needs some CPU-power):
On the machine receiving the stream from the camera, don't use FFMPEG but gstreamer. It is able to receive and decode the RTSP-stream, re-encode it and stream it to the icecast server. Example pipeline (only video, no audio):
gst-launch-1.0 rtspsrc location=rtsp://192.168.1.234:554 user-id=admin user-pw=123456 ! rtph264depay ! avdec_h264 ! vp8enc threads=2 deadline=10000 ! webmmux streamable=true ! shout2send password=pass ip=<IP_OF_ICECAST_SERVER> port=12000 mount=cam.webm
=> You can then use the <video> tag with the URL of the icecast-stream (http://127.0.0.1:12000/cam.webm) and it will work in every browser and device that supports webm
You can't.
Interfaces define contracts that other objects implement and therefore have no state that needs to be initialized.
If you have some state that needs to be initialized, you should consider using an abstract base class instead.

git branch --unset-upstream
stops tracking all the local branches, which is not desirable.
Remove the [branch "branch-name"]
section from the .git/config
file followed by
git branch -D 'branch-name' && git branch -D -r 'origin/branch-name'
works out the best for me.
I prefer, putting git in environment variable and just calling
c:\Users\[myname]>sh
or
c:\Users\[myname]>bash
Steps to create Environment variable (Win7)
In the section User variables, hit button NEW, put variable name as GIT_HOME
, value as (folder-where-you-installed-git).
c:\tools\git
, others maybe have C:\Program Files\Git
find the PATH
environment variable and select it. Click Edit. (If the PATH environment variable does not exist, click New).
%GIT_HOME%
and %GIT_HOME%\bin
. Click OK. Close all remaining windows by clicking OK.sh
or bash
or git-bash
here is the best way in a similar function
function cart_stats($cart_id){
$sql = "select sum(price) sum_bids, count(*) total_bids from carts_bids where cart_id = '$cart_id'";
$rs = mysql_query($sql);
$row = mysql_fetch_object($rs);
$total_bids = $row->total_bids;
$sum_bids = $row->sum_bids;
$avarage = $sum_bids/$total_bids;
$array["total_bids"] = "$total_bids";
$array["avarage"] = " $avarage";
return $array;
}
and you get the array data like this
$data = cart_stats($_GET['id']);
<?=$data['total_bids']?>
Here you can simply use:
SendKeys "{ENTER}"
at the end of code linked to the Username field.
And so you can skip pressing ENTER Key once (one time).
And as a result, the next button ("Log In" button here) will be activated. And when you press ENTER once (your desired outcome), It will run code which is linked with "Log In" button.
For me it was because they are not in the same namespace. After I remove my AppStart from "project.Startup.AppStart" and let they both Startup.cs and Startup.Auth.cs with "project.Startup" namespace, everything was back to work perfectly.
I hope it help!
Upping the directive in the virtualhost for KeepAliveTimeout to 60 solved this for me.
The HTML tabindex atribute is responsible for indicating if an element is reachable by keyboard navigation. When the user presses the Tab key the focus is shifted from one element to another. By using the tabindex atribute, the tab order flow is shifted.
They can also provide a kind of naming collision protection for plugin data. For example, the new Change Data Capture feature in SQL Server 2008 puts the tables it uses in a separate cdc schema. This way, they don't have to worry about a naming conflict between a CDC table and a real table used in the database, and for that matter can deliberately shadow the names of the real tables.
This is not of much value in Java (1.5+) except when the type of object is Boolean
. In which case, this can still be handy.
if (object = null)
will not cause compilation failure in Java 1.5+ if object is Boolean
but would throw a NullPointerException
at runtime.
Here is another dirty hack :)
.application-title > img {
display: none;
}
.application-title::before {
content: url(path/example.jpg);
}
You can do this with git log
:
git log origin..
Assuming that origin
is the name of your upstream, leaving off any revision name after ..
implies HEAD
, which lists the new commits that haven't been pushed.
In my case, it was neither systemd nor a cron job, but it was snap. So I had to run:
sudo snap stop docker
sudo snap remove docker
... and the last command actually never ended, I don't know why: this snap thing is really a pain. So I also ran:
sudo apt purge snap
:-)
Add permission [Domain Users] to your web security.
This answer is correct but has a problem: fields not defined. If you have more then one field, you can not recognize which one has error.
with this change you can display field name:
{% if form.errors %}
{% for field in form %}
{% for error in field.errors %}
<div class="alert alert-danger">
<strong>{{ field.label }}</strong><span>{{ error|escape }}</strong>
</div>
{% endfor %}
{% endfor %}
{% for error in form.non_field_errors %}
<div class="alert alert-danger">
<strong>{{ error|escape }}</strong>
</div>
{% endfor %}
{% endif %}
I feel we had a related discussion earlier: How to upload preview image before upload through JavaScript
It's not magic.
The behavior of this code in C is described in section 6.7.8.21 of the C specification (online draft of C spec): for the elements that don't have a specified value, the compiler initializes pointers to NULL and arithmetic types to zero (and recursively applies this to aggregates).
The behavior of this code in C++ is described in section 8.5.1.7 of the C++ specification (online draft of C++ spec): the compiler aggregate-initializes the elements that don't have a specified value.
Also, note that in C++ (but not C), you can use an empty initializer list, causing the compiler to aggregate-initialize all of the elements of the array:
char array[100] = {};
As for what sort of code the compiler might generate when you do this, take a look at this question: Strange assembly from array 0-initialization
I use environment for that. It works automatically and you don't have to create new injectable service and most usefull for me, don't need to import via constructor.
1) Create environment variable in your environment.ts
export const environment = {
...
// runtime variables
isContentLoading: false,
isDeployNeeded: false
}
2) Import environment.ts in *.ts file and create public variable (i.e. "env") to be able to use in html template
import { environment } from 'environments/environment';
@Component(...)
export class TestComponent {
...
env = environment;
}
3) Use it in template...
<app-spinner *ngIf='env.isContentLoading'></app-spinner>
in *.ts ...
env.isContentLoading = false
(or just environment.isContentLoading in case you don't need it for template)
You can create your own set of globals within environment.ts like so:
export const globals = {
isContentLoading: false,
isDeployNeeded: false
}
and import directly these variables (y)

Note: this answer is outdated. Newer versions of requests
support getting the request content directly, as AntonioHerraizS's answer documents.
It's not possible to get the true raw content of the request out of requests
, since it only deals with higher level objects, such as headers and method type. requests
uses urllib3
to send requests, but urllib3
also doesn't deal with raw data - it uses httplib
. Here's a representative stack trace of a request:
-> r= requests.get("http://google.com")
/usr/local/lib/python2.7/dist-packages/requests/api.py(55)get()
-> return request('get', url, **kwargs)
/usr/local/lib/python2.7/dist-packages/requests/api.py(44)request()
-> return session.request(method=method, url=url, **kwargs)
/usr/local/lib/python2.7/dist-packages/requests/sessions.py(382)request()
-> resp = self.send(prep, **send_kwargs)
/usr/local/lib/python2.7/dist-packages/requests/sessions.py(485)send()
-> r = adapter.send(request, **kwargs)
/usr/local/lib/python2.7/dist-packages/requests/adapters.py(324)send()
-> timeout=timeout
/usr/local/lib/python2.7/dist-packages/requests/packages/urllib3/connectionpool.py(478)urlopen()
-> body=body, headers=headers)
/usr/local/lib/python2.7/dist-packages/requests/packages/urllib3/connectionpool.py(285)_make_request()
-> conn.request(method, url, **httplib_request_kw)
/usr/lib/python2.7/httplib.py(958)request()
-> self._send_request(method, url, body, headers)
Inside the httplib
machinery, we can see HTTPConnection._send_request
indirectly uses HTTPConnection._send_output
, which finally creates the raw request and body (if it exists), and uses HTTPConnection.send
to send them separately. send
finally reaches the socket.
Since there's no hooks for doing what you want, as a last resort you can monkey patch httplib
to get the content. It's a fragile solution, and you may need to adapt it if httplib
is changed. If you intend to distribute software using this solution, you may want to consider packaging httplib
instead of using the system's, which is easy, since it's a pure python module.
Alas, without further ado, the solution:
import requests
import httplib
def patch_send():
old_send= httplib.HTTPConnection.send
def new_send( self, data ):
print data
return old_send(self, data) #return is not necessary, but never hurts, in case the library is changed
httplib.HTTPConnection.send= new_send
patch_send()
requests.get("http://www.python.org")
which yields the output:
GET / HTTP/1.1
Host: www.python.org
Accept-Encoding: gzip, deflate, compress
Accept: */*
User-Agent: python-requests/2.1.0 CPython/2.7.3 Linux/3.2.0-23-generic-pae
I have some useful comments. Because I had similar problem with location of figures. I used package "wrapfig" that allows to make figures wrapped by text. Something like
...
\usepackage{wrapfig}
\usepackage{graphicx}
...
\begin{wrapfigure}{r}{53pt}
\includegraphics[width=53pt]{cone.pdf}
\end{wrapfigure}
In options {r}
means to put figure from right side. {l}
can be use for left side.
I suggest Validator.nu's parser, based on the HTML5 parsing algorithm. It is the parser used in Mozilla from 2010-05-03
you can also use for loop to append or write data to a file. example:
for i in {1..10}; do echo "Hello Linux Terminal"; >> file.txt done
">>" is used to append.
">" is used to write.
You are close already. Just make sure to hide the checkbox and associate it with a label you style via input[checkbox] + label

Pillow is released with installation wheels on Windows:
We provide Pillow binaries for Windows compiled for the matrix of supported Pythons in both 32 and 64-bit versions in wheel, egg, and executable installers. These binaries have all of the optional libraries included
https://pillow.readthedocs.io/en/3.3.x/installation.html#basic-installation
Update: Python 3.6 is now supported by Pillow. Install with pip install pillow
and check https://pillow.readthedocs.io/en/latest/installation.html for more information.
However, Python 3.6 is still in alpha and not officially supported yet, although the tests do all pass for the nightly Python builds (currently 3.6a4).
https://travis-ci.org/python-pillow/Pillow/jobs/155605577
If it's somehow possible to install the 3.5 wheel for 3.6, that's your best bet. Otherwise, zlib notwithstanding, you'll need to build from source, requiring an MS Visual C++ compiler, and which isn't straightforward. For tips see:
https://pillow.readthedocs.io/en/3.3.x/installation.html#building-from-source
And also see how it's built for Windows on AppVeyor CI (but not yet 3.5 or 3.6):
https://github.com/python-pillow/Pillow/tree/master/winbuild
Failing that, downgrade to Python 3.5 or wait until 3.6 is supported by Pillow, probably closer to the 3.6's official release.
Assuming a Windows installation, do please refer to this:
http://www.oracle-base.com/articles/misc/ManualOracleUninstall.php
- Uninstall all Oracle components using the Oracle Universal Installer (OUI).
- Run regedit.exe and delete the HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE key. This contains registry entires for all Oracle products.
- Delete any references to Oracle services left behind in the following part of the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Ora*
It should be pretty obvious which ones relate to Oracle.- Reboot your machine.
- Delete the "C:\Oracle" directory, or whatever directory is your ORACLE_BASE.
- Delete the "C:\Program Files\Oracle" directory.
- Empty the contents of your "C:\temp" directory.
- Empty your recycle bin.
Calling additional attention to some great comments that were left here:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ORACLE
key from the registry.%ORACLE_HOME%
.%PATH%
.This set of instructions happens to match an almost identical process that I had reverse-engineered myself over the years after a few messed-up Oracle installs, and has almost always met the need.
Note that even if the OUI is no longer available or doesn't work, simply following the remaining steps should still be sufficient.
(Revision #7 reverted as to not misquote the original source, and to not remove credit to the other comments that contributed to the answer. Further edits are appreciated (and then please remove this comment), if a way can be found to maintain these considerations.)
Intel HD Graphics is usually the on-CPU graphics chip in newer Core i3/i5/i7 processors.
As far as I know it doesn't support CUDA (which is a proprietary NVidia technology), but OpenCL is supported by NVidia, ATi and Intel.
There's quite a nice 'hack' here - https://stackoverflow.com/a/14565029 where you use an iframe with an empty src to generate the alert / confirm message - it doesn't work on Android (for security's sake) - but may suit your scenario.
Once you have decoded the JSON, the result is a JavaScript object. Just manipulate it as you would any other object. For example:
data.busNum = 12345;
...
rem This is the command line version
cscript "C:\Users\guest\Desktop\123\MyScript.vbs"
OR
rem This is the windowed version
wscript "C:\Users\guest\Desktop\123\MyScript.vbs"
You can also add the option //e:vbscript
to make sure the scripting engine will recognize your script as a vbscript.
Windows/DOS batch files doesn't require escaping \
like *nix.
You can still use "C:\Users\guest\Desktop\123\MyScript.vbs"
, but this requires the user has *.vbs
associated to wscript
.
The files selected are stored in an array: [input].files
For example, you can access the items
// assuming there is a file input with the ID `my-input`...
var files = document.getElementById("my-input").files;
for (var i = 0; i < files.length; i++)
{
alert(files[i].name);
}
For jQuery-comfortable people, it's similarly easy
// assuming there is a file input with the ID `my-input`...
var files = $("#my-input")[0].files;
for (var i = 0; i < files.length; i++)
{
alert(files[i].name);
}
Multiple SQL statements must be executed with the mysqli_multi_query()
function.
Example (MySQLi Object-oriented):
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO names (firstname, lastname)
VALUES ('inpute value here', 'inpute value here');";
$sql .= "INSERT INTO phones (landphone, mobile)
VALUES ('inpute value here', 'inpute value here');";
if ($conn->multi_query($sql) === TRUE) {
echo "New records created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
By default verbose = 1,
verbose = 1, which includes both progress bar and one line per epoch
verbose = 0, means silent
verbose = 2, one line per epoch i.e. epoch no./total no. of epochs
The easiest way to save the packages from an environment to be installed in another computer is:
$ conda list -e > req.txt
then you can install the environment using
$ conda create -n <environment-name> --file req.txt
if you use pip
, please use the following commands: reference https://pip.pypa.io/en/stable/reference/pip_freeze/
$ env1/bin/pip freeze > requirements.txt
$ env2/bin/pip install -r requirements.txt
Based on my comment to the accepted answer, there are a lot potential pitfalls that you may encounter by declaring font-sizes smaller than 12px
. By declaring styles that lead to computed font-sizes of less than 12px
, like so:
html {
font-size: 8px;
}
p {
font-size: 1.4rem;
}
// Computed p size: 11px.
You'll run into issues with browsers, like Chrome with a Chinese language pack that automatically renders any font sizes computed under 12px
as 12px
. So, the following is true:
h6 {
font-size: 12px;
}
p {
font-size: 8px;
}
// Both render at 12px in Chrome with a Chinese language pack.
// How unpleasant of a surprise.
I would also argue that for accessibility reasons, you generally shouldn't use sizes under 12px. You might be able to make a case for captions and the like, but again--prepare to be surprised under some browser setups, and prepared to make your grandma squint when she's trying to read your content.
I would instead, opt for something like this:
h1 {
font-size: 2.5rem;
}
h2 {
font-size: 2.25rem;
}
h3 {
font-size: 2rem;
}
h4 {
font-size: 1.75rem;
}
h5 {
font-size: 1.5rem;
}
h6 {
font-size: 1.25rem;
}
p {
font-size: 1rem;
}
@media (max-width: 480px) {
html {
font-size: 12px;
}
}
@media (min-width: 480px) {
html {
font-size: 13px;
}
}
@media (min-width: 768px) {
html {
font-size: 14px;
}
}
@media (min-width: 992px) {
html {
font-size: 15px;
}
}
@media (min-width: 1200px) {
html {
font-size: 16px;
}
}
You'll find that tons of sites that have to focus on accessibility use rather large font sizes, even for p
elements.
As a side note, setting margin-bottom
equal to the font-size
usually also tends to be attractive, i.e.:
h1 {
font-size: 2.5rem;
margin-bottom: 2.5rem;
}
Good luck.
Use "&
" instead of "&".
With the constructor:
// create a vector with 20 integer elements
std::vector<int> arr(20);
for(int x = 0; x < 20; ++x)
arr[x] = x;
try
raw_input('Enter your input:') # If you use Python 2
input('Enter your input:') # If you use Python 3
and if you want to have a numeric value just convert it:
try:
mode=int(raw_input('Input:'))
except ValueError:
print "Not a number"
Firstly, double quote character is nothing special in regex - it's just another character, so it doesn't need escaping from the perspective of regex.
However, because java uses double quotes to delimit String constants, if you want to create a string in java with a double quote in it, you must escape them.
This code will test if your String matches:
if (str.matches("\".*\"")) {
// this string starts and end with a double quote
}
Note that you don't need to add start and end of input markers (^
and $
) in the regex, because matches()
requires that the whole input be matched to return true - ^
and $
are implied.
NOTE: you can use NVM software to do this in a more nodejs fashionway. However i got issues in one machine that didn't let me use NVM. So i have to look for an alternative ;-)
You can manually download and install.
go to nodejs > download > other releases http://nodejs.org/dist/
choose the version you are looking for http://nodejs.org/dist/v0.8.18/
choose distro files corresponding your environmment and download (take care of 32bits/64bits version). Example: http://nodejs.org/dist/v0.8.18/node-v0.8.18-linux-x64.tar.gz
Extract files and follow instructions on README.md :
To build:
Prerequisites (Unix only):
* Python 2.6 or 2.7 * GNU Make 3.81 or newer * libexecinfo (FreeBSD and OpenBSD only)
Unix/Macintosh:
./configure make make install
If your python binary is in a non-standard location or has a non-standard name, run the following instead:
export PYTHON=/path/to/python $PYTHON ./configure make make install
Windows:
vcbuild.bat
To run the tests:
Unix/Macintosh:
make test
Windows:
vcbuild.bat test
To build the documentation:
make doc
To read the documentation:
man doc/node.1
Maybe you want to (must to) move the folder to a more apropiate place like /usr/lib/nodejs/node-v0.8.18/ then create a Symbolic Lynk on /usr/bin to get acces to your install from anywhere.
sudo mv /extracted/folder/node-v0.8.18 /usr/lib/nodejs/node-v0.8.18
sudo ln -s /usr/lib/nodejs/node-v0.8.18/bin/node /usr/bin/node
And if you want different release in the same machine you can use debian alternatives. Proceed in the same way posted before to download a second release. For example the latest release.
http://nodejs.org/dist/latest/ -> http://nodejs.org/dist/latest/node-v0.10.28-linux-x64.tar.gz
Move to your favorite destination, the same of the rest of release you want to install.
sudo mv /extracted/folder/node-v0.10.28 /usr/lib/nodejs/node-v0.10.28
Follow instructions of the README.md file. Then update the alternatives, for each release you have dowload install the alternative with.
sudo update-alternatives --install genname symlink altern priority [--slave genname symlink altern]
Add a group of alternatives to the system. genname is the
generic name for the master link, symlink is the name of its
symlink in the alternatives directory, and altern is the
alternative being introduced for the master link. The arguments
after --slave are the generic name, symlink name in the
alternatives directory and alternative for a slave link. Zero
or more --slave options, each followed by three arguments, may
be specified.
If the master symlink specified exists already in the
alternatives system’s records, the information supplied will be
added as a new set of alternatives for the group. Otherwise, a
new group, set to automatic mode, will be added with this
information. If the group is in automatic mode, and the newly
added alternatives’ priority is higher than any other installed
alternatives for this group, the symlinks will be updated to
point to the newly added alternatives.
for example:
sudo update-alternatives --install /usr/bin/node node /usr/lib/nodejs/node-v0.10.28 0 --slave /usr/share/man/man1/node.1.gz node.1.gz /usr/lib/nodejs/node-v0.10.28/share/man/man1/node.1
Then you can use update-alternatives --config node
to choose between any number of releases instaled in your machine.
Try with this one:
result = re.search(r"\w+( )\w+", text)
I'm using version 4.0.3 of MAMP along with phpmyadmin. The top of /Applications/MAMP/bin/phpMyAdmin/libraries/config.default.php reads:

To follow up on the previous answer using mail :
Often times one's html output is interpreted by the client mailer, which may not format things using a fixed-width font. Thus your nicely formatted ascii alignment gets all messed up. To send old-fashioned fixed-width the way the God intended, try this:
{ echo -e "<pre>"
echo "Descriptive text here."
shell_command_1_here
another_shell_command
cat <<EOF
This is the ending text.
</pre><br>
</div>
EOF
} | mail -s "$(echo -e 'Your subject.\nContent-Type: text/html')" [email protected]
You don't necessarily need the "Descriptive text here." line, but I have found that sometimes the first line may, depending on its contents, cause the mail program to interpret the rest of the file in ways you did not intend. Try the script with simple descriptive text first, before fine tuning the output in the way that you want.
Just use .split(',')
:
var str = "How are you doing today?";
var n = str.split(" ");
Making a small tweak to the inside function and using lapply on an index instead of the actual list itself gets this doing what you want
x <- c("yes", "no", "maybe", "no", "no", "yes")
y <- c("red", "blue", "green", "green", "orange")
list.xy <- list(x=x, y=y)
WORD.C <- function(WORDS){
require(wordcloud)
L2 <- lapply(WORDS, function(x) as.data.frame(table(x), stringsAsFactors = FALSE))
# Takes a dataframe and the text you want to display
FUN <- function(X, text){
windows()
wordcloud(X[, 1], X[, 2], min.freq=1)
mtext(text, 3, padj=-4.5, col="red") #what I'm trying that isn't working
}
# Now creates the sequence 1,...,length(L2)
# Loops over that and then create an anonymous function
# to send in the information you want to use.
lapply(seq_along(L2), function(i){FUN(L2[[i]], names(L2)[i])})
# Since you asked about loops
# you could use i in seq_along(L2)
# instead of 1:length(L2) if you wanted to
#for(i in 1:length(L2)){
# FUN(L2[[i]], names(L2)[i])
#}
}

If you're still getting a env: ruby_executable_hooks: No such file or directory
when calling some Ruby package, that means RVM left a little gift for you in your $PATH
.
Run the following to find the offending scripts:
grep '#!/usr/bin/env ruby_executable_hooks' /usr/local/bin/*
Then rm
all the matches. You'll have to reinstall all of those libraries with an RVM-free gem
, of course.

I know this is an old question, but here's an alternative. I'd store that image data in an array, then, on mouse move event over the canvas:
var index = (Math.floor(y) * canvasWidth + Math.floor(x)) * 4
var r = data[index]
var g = data[index + 1]
var b = data[index + 2]
var a = data[index + 3]
A lot easier than getting the imageData everytime.
To find the version of the java in the classfiles I used:
javap -verbose <classname>
which announces the version at the start as
minor version: 0
major version: 49
which corresponds to Java 1.5
If you are developing a cordova app, make sure to change the version and bundle identifier in the config.xml
as well
This error occurs when you push the data from your local directory to your remote git repository by following git command: git push -u origin master
As local directory and git remote directory's files conflicted.
Solution :
After committing all files to staging follow below steps.
Fetch the files from the remote repository as its conflict with the local working directory.
git pull <remoter-url> <branch-name>
Commit the changes again.
git add -A
git commit -m ‘<comment>'
After committed merge files with both directory you can use
git push -u origin master
This will fix the issue. Thanks.
You're running your Python 3 code with a Python 2 interpreter. If you weren't, your print
statement would throw up a SyntaxError
before it ever prompted you for input.
The result is that you're using Python 2's input
, which tries to eval
your input (presumably sdas
), finds that it's invalid Python, and dies.
You can try using System.arraycopy()
int[] src = new int[]{1,2,3,4,5};
int[] dest = new int[5];
System.arraycopy( src, 0, dest, 0, src.length );
But, probably better to use clone() in most cases:
int[] src = ...
int[] dest = src.clone();
The standard SQL way is to use like:
where @stringVar like '%thisstring%'
That is in a query statement. You can also do this in TSQL:
if @stringVar like '%thisstring%'
If you have deleted lot of files and folders, just do this
git commit -a -m .
git push
Local storage: It keeps store the user information data without expiration date this data will not be deleted when user closed the browser windows it will be available for day, week, month and year.
In Local storage can store 5-10mb offline data.
//Set the value in a local storage object
localStorage.setItem('name', myName);
//Get the value from storage object
localStorage.getItem('name');
//Delete the value from local storage object
localStorage.removeItem(name);//Delete specifice obeject from local storege
localStorage.clear();//Delete all from local storege
Session Storage: It is same like local storage date except it will delete all windows when browser windows closed by a web user.
In Session storage can store upto 5 mb data
//set the value to a object in session storege
sessionStorage.myNameInSession = "Krishna";
Session: A session is a global variable stored on the server. Each session is assigned a unique id which is used to retrieve stored values.
Cookies: Cookies are data, stored in small text files as name-value pairs, on your computer. Once a cookie has been set, all page requests that follow return the cookie name and value.
Aditionally to the answer from @srk, you should uninstall package setuptools
:
python -m pip uninstall pip setuptools
If you want to uninstall all other packages first, this answer has some hints: https://stackoverflow.com/a/11250821/265954
Note: before you use the commands from that answer, please carefully read the comments about side effects and how to avoid uninstalling pip
and setuptools
too early. E.g. pip freeze | grep -v "^-e" | grep -v "^(setuptools|pip)" | xargs pip uninstall -y
TRY
/CATCH
error handling can take place either within or outside of a procedure (or both). The examples below demonstrate error handling in both cases.
If you want to experiment further, you can fork the query on Stack Exchange Data Explorer.
(This uses a temporary stored procedure... we can't create regular SP's on SEDE, but the functionality is the same.)
--our Stored Procedure
create procedure #myProc as --we can only create #temporary stored procedures on SEDE.
begin
BEGIN TRY
print 'This is our Stored Procedure.'
print 1/0 --<-- generate a "Divide By Zero" error.
print 'We are not going to make it to this line.'
END TRY
BEGIN CATCH
print 'This is the CATCH block within our Stored Procedure:'
+ ' Error Line #'+convert(varchar,ERROR_LINE())
+ ' of procedure '+isnull(ERROR_PROCEDURE(),'(Main)')
--print 1/0 --<-- generate another "Divide By Zero" error.
-- uncomment the line above to cause error within the CATCH ¹
END CATCH
end
go
--our MAIN code block:
BEGIN TRY
print 'This is our MAIN Procedure.'
execute #myProc --execute the Stored Procedure
--print 1/0 --<-- generate another "Divide By Zero" error.
-- uncomment the line above to cause error within the MAIN Procedure ²
print 'Now our MAIN sql code block continues.'
END TRY
BEGIN CATCH
print 'This is the CATCH block for our MAIN sql code block:'
+ ' Error Line #'+convert(varchar,ERROR_LINE())
+ ' of procedure '+isnull(ERROR_PROCEDURE(),'(Main)')
END CATCH
Here's the result of running the above sql as-is:
This is our MAIN Procedure.
This is our Stored Procedure.
This is the CATCH block within our Stored Procedure: Error Line #5 of procedure #myProc
Now our MAIN sql code block continues.
¹ Uncommenting the "additional error line" from the Stored Procedure's CATCH block will produce:
This is our MAIN procedure.
This is our Stored Procedure.
This is the CATCH block within our Stored Procedure: Error Line #5 of procedure #myProc
This is the CATCH block for our MAIN sql code block: Error Line #13 of procedure #myProc
² Uncommenting the "additional error line" from the MAIN procedure will produce:
This is our MAIN Procedure.
This is our Stored Pprocedure.
This is the CATCH block within our Stored Procedure: Error Line #5 of procedure #myProc
This is the CATCH block for our MAIN sql code block: Error Line #4 of procedure (Main)
On topic of stored procedures and error handling, it can be helpful (and tidier) to use a single, dynamic, stored procedure to handle errors for multiple other procedures or code sections.
Here's an example:
--our error handling procedure
create procedure #myErrorHandling as
begin
print ' Error #'+convert(varchar,ERROR_NUMBER())+': '+ERROR_MESSAGE()
print ' occurred on line #'+convert(varchar,ERROR_LINE())
+' of procedure '+isnull(ERROR_PROCEDURE(),'(Main)')
if ERROR_PROCEDURE() is null --check if error was in MAIN Procedure
print '*Execution cannot continue after an error in the MAIN Procedure.'
end
go
create procedure #myProc as --our test Stored Procedure
begin
BEGIN TRY
print 'This is our Stored Procedure.'
print 1/0 --generate a "Divide By Zero" error.
print 'We will not make it to this line.'
END TRY
BEGIN CATCH
execute #myErrorHandling
END CATCH
end
go
BEGIN TRY --our MAIN Procedure
print 'This is our MAIN Procedure.'
execute #myProc --execute the Stored Procedure
print '*The error halted the procedure, but our MAIN code can continue.'
print 1/0 --generate another "Divide By Zero" error.
print 'We will not make it to this line.'
END TRY
BEGIN CATCH
execute #myErrorHandling
END CATCH
This is our MAIN procedure.
This is our stored procedure.
Error #8134: Divide by zero error encountered.
occurred on line #5 of procedure #myProc
*The error halted the procedure, but our MAIN code can continue.
Error #8134: Divide by zero error encountered.
occurred on line #5 of procedure (Main)
*Execution cannot continue after an error in the MAIN procedure.
In the scope of a TRY
/CATCH
block, the following system functions can be used to obtain information about the error that caused the CATCH
block to be executed:
ERROR_NUMBER()
returns the number of the error. ERROR_SEVERITY()
returns the severity. ERROR_STATE()
returns the error state number. ERROR_PROCEDURE()
returns the name of the stored procedure or trigger where the error occurred. ERROR_LINE()
returns the line number inside the routine that caused the error. ERROR_MESSAGE()
returns the complete text of the error message. The text includes the values supplied for any substitutable parameters, such as lengths, object names, or times. (Source)
Note that there are two types of SQL errors: Terminal and Catchable. TRY
/CATCH
will [obviously] only catch the "Catchable" errors. This is one of a number of ways of learning more about your SQL errors, but it probably the most useful.
It's "better to fail now" (during development) compared to later because, as Homer says . . .

These specific lines are the usual wrapper for jQuery plugins:
"...to make sure that your plugin doesn't collide with other libraries that might use the dollar sign, it's a best practice to pass jQuery to a self executing function (closure) that maps it to the dollar sign so it can't be overwritten by another library in the scope of its execution."
(function( $ ){
$.fn.myPlugin = function() {
// Do your awesome plugin stuff here
};
})( jQuery );
$this->db->count_all_results
is part of an Active Record query (preparing the query, to only return the number, not the actual results).
$query->num_rows()
is performed on a resultset object (after returning results from the DB).
There is nothing wrong with count() here, "trends" is the only key that is being counted in this case, you can try doing:
count($obj->trends);
Or:
count($obj->trends['2009-08-21 11:05']);
Or maybe even doing:
count($obj, COUNT_RECURSIVE);
After Python 3.5 you can also use:
import subprocess
f = open('test.txt', 'w')
process = subprocess.run(['ls', '-la'], stdout=subprocess.PIPE, universal_newlines=True)
f.write(process.stdout)
f.close()
The execution of the command is blocking and the output will be in process.stdout.

What is the URL format used by jTDS?
The URL format for jTDS is:
jdbc:jtds:<server_type>://<server>[:<port>][/<database>][;<property>=<value>[;...]]
... domain Specifies the Windows domain to authenticate in. If present and the user name and password are provided, jTDS uses Windows (NTLM) authentication instead of the usual SQL Server authentication (i.e. the user and password provided are the domain user and password). This allows non-Windows clients to log in to servers which are only configured to accept Windows authentication.
If the domain parameter is present but no user name and password are provided, jTDS uses its native Single-Sign-On library and logs in with the logged Windows user's credentials (for this to work one would obviously need to be on Windows, logged into a domain, and also have the SSO library installed -- consult README.SSO in the distribution on how to do this).
You can try this:
public static <T> T coalesce(T... t) {
return Stream.of(t).filter(Objects::nonNull).findFirst().orElse(null);
}
Based on this response
Neither code is always better. They do different things, so they are good at different things.
InvariantCultureIgnoreCase
uses comparison rules based on english, but without any regional variations. This is good for a neutral comparison that still takes into account some linguistic aspects.
OrdinalIgnoreCase
compares the character codes without cultural aspects. This is good for exact comparisons, like login names, but not for sorting strings with unusual characters like é
or ö
. This is also faster because there are no extra rules to apply before comparing.
If you're checking for explicit types, why are you declaring those variables as T
's?
T HowToCast<T>(T t)
{
if (typeof(T) == typeof(string))
{
var newT1 = "some text";
var newT2 = t; //this builds but I'm not sure what it does under the hood.
var newT3 = t.ToString(); //for sure the string you want.
}
return t;
}
what are you exactly want check for login or user ? a login is created on server level and a user is created at database level so a login is unique in server
also a user is created against a login, a user without login is an orphaned user and is not useful as u cant carry out sql server login without a login
maybe u need this
check for login
select 'X' from master.dbo.syslogins where loginname=<username>
the above query return 'X' if login exists else return null
then create a login
CREATE LOGIN <username> with PASSWORD=<password>
this creates a login in sql server .but it accepts only strong passwords
create a user in each database you want to for login as
CREATE USER <username> for login <username>
assign execute rights to user
GRANT EXECUTE TO <username>
YOU MUST HAVE SYSADMIN permissions or say 'sa' for short
you can write a sql procedure for that on a database
create proc createuser
(
@username varchar(50),
@password varchar(50)
)
as
begin
if not exists(select 'X' from master.dbo.syslogins where loginname=@username)
begin
if not exists(select 'X' from sysusers where name=@username)
begin
exec('CREATE LOGIN '+@username+' WITH PASSWORD='''+@password+'''')
exec('CREATE USER '+@username+' FOR LOGIN '+@username)
exec('GRANT EXECUTE TO '+@username)

The problem with merge sort is the merge, if you don't actually need to implement the merge, then it is pretty simple (for a vector of ints):
#include <algorithm>
#include <vector>
using namespace std;
typedef vector<int>::iterator iter;
void mergesort(iter b, iter e) {
if (e -b > 1) {
iter m = b + (e -b) / 2;
mergesort(b, m);
mergesort(m, e);
inplace_merge(b, m, e);
}

If you don't want to roll your own, there is a function available in the pydoc
module that does exactly this:
from pydoc import locate
my_class = locate('my_package.my_module.MyClass')
The advantage of this approach over the others listed here is that locate
will find any python object at the provided dotted path, not just an object directly within a module. e.g. my_package.my_module.MyClass.attr
.
If you're curious what their recipe is, here's the function:
def locate(path, forceload=0):
"""Locate an object by name or dotted path, importing as necessary."""
parts = [part for part in split(path, '.') if part]
module, n = None, 0
while n < len(parts):
nextmodule = safeimport(join(parts[:n+1], '.'), forceload)
if nextmodule: module, n = nextmodule, n + 1
else: break
if module:
object = module
else:
object = __builtin__
for part in parts[n:]:
try:
object = getattr(object, part)
except AttributeError:
return None
return object
It relies on pydoc.safeimport
function. Here are the docs for that:
"""Import a module; handle errors; return None if the module isn't found.
If the module *is* found but an exception occurs, it's wrapped in an
ErrorDuringImport exception and reraised. Unlike __import__, if a
package path is specified, the module at the end of the path is returned,
not the package at the beginning. If the optional 'forceload' argument
is 1, we reload the module from disk (unless it's a dynamic extension)."""
You can look at the headers or libs installed. pkg-config can tell you where they are:
pkg-config --cflags opencv
pkg-config --libs opencv
Alternatively you can write a simple program and print the following defs:
CV_MAJOR_VERSION
CV_MINOR_VERSION
A similar question has been also asked here:
When the JVM loads classes, or otherwise sees a literal string, or some code intern
s a string, it adds the string to a mostly-hidden lookup table that has one copy of each such string. If another copy is added, the runtime arranges it so that all the literals refer to the same string object. This is called "interning". If you say something like
String s = "test";
return (s == "test");
it'll return true
, because the first and second "test" are actually the same object. Comparing interned strings this way can be much, much faster than String.equals
, as there's a single reference comparison rather than a bunch of char
comparisons.
You can add a string to the pool by calling String.intern()
, which will give you back the pooled version of the string (which could be the same string you're interning, but you'd be crazy to rely on that -- you often can't be sure exactly what code has been loaded and run up til now and interned the same string). The pooled version (the string returned from intern
) will be equal to any identical literal. For example:
String s1 = "test";
String s2 = new String("test"); // "new String" guarantees a different object
System.out.println(s1 == s2); // should print "false"
s2 = s2.intern();
System.out.println(s1 == s2); // should print "true"
This worked for me :
select option {
color: black;
}
select:not(:checked) {
color: gray;
}
With bash version >= 4.2:
printf "%(%H:%M)T\n"
or
printf -v foo "%(%H:%M)T\n"
echo "$foo"
See: man bash
int elem = 42;
std::vector<int> v;
v.push_back(elem);
if(std::find(v.begin(), v.end(), elem) != v.end())
{
//elem exists in the vector
}
The first answer from @carlos worked for me:
session.getProperties().put("mail.smtp.ssl.trust", "smtp.gmail.com");
I have tested the property below and worked perfectly for me too:
session.getProperties().put("mail.smtp.starttls.enable", "true");
The two properties alone solved this type of problem, but by guarantee I used both.
This question seems to be answered, however for completeness, I would add another approach.
You can use a unique ID number generator which is based on Twitter's Snowflake id generator. C# implementation can be found here.
var id64Generator = new Id64Generator();
// ...
public string generateID(string sourceUrl)
{
return string.Format("{0}_{1}", sourceUrl, id64Generator.GenerateId());
}
Note that one of very nice features of that approach is possibility to have multiple generators on independent nodes (probably something useful for a search engine) generating real time, globally unique identifiers.
// node 0
var id64Generator = new Id64Generator(0);
// node 1
var id64Generator = new Id64Generator(1);
// ... node 10
var id64Generator = new Id64Generator(10);
OK, simply and in short words, they mean ordered and not ordered...!
Stack: In stack items, things get on the top of each-other, means gonna be faster and more efficient to be processed!...
So there is always an index to point the specific item, also processing gonna be faster, there is relationship between the items as well!...
Heap: No order, processing gonna be slower and values are messed up together with no specific order or index... there are random and there is no relationship between them... so execution and usage time could be vary...
I also create the image below to show how they may look like:
Within an htaccess file, the scope of the <Files>
directive only applies to that directory (I guess to avoid confusion when rules/directives in the htaccess of subdirectories get applied superceding ones from the parent).
So you can have:
<Files "log.txt">
Order Allow,Deny
Deny from all
</Files>
For Apache 2.4+, you'd use:
<Files "log.txt">
Require all denied
</Files>
In an htaccess file in your inscription
directory. Or you can use mod_rewrite to sort of handle both cases deny access to htaccess file as well as log.txt:
RewriteRule /?\.htaccess$ - [F,L]
RewriteRule ^/?inscription/log\.txt$ - [F,L]

While I tried the approach above, it becomes a complete disaster with mvc. Your controller passing a model and your view using a strongly typed model become too difficult to work with.
Get your Dataset into a List ..... I have a repository pattern and here is an example of getting a dataset from an old school asmx web service private readonly CISOnlineSRVDEV.ServiceSoapClient _ServiceSoapClient;
public Get_Client_Repository()
: this(new CISOnlineSRVDEV.ServiceSoapClient())
{
}
public Get_Client_Repository(CISOnlineSRVDEV.ServiceSoapClient serviceSoapClient)
{
_ServiceSoapClient = serviceSoapClient;
}
public IEnumerable<IClient> GetClient(IClient client)
{
// **** Calling teh web service with passing in the clientId and returning a dataset
DataSet dataSet = _ServiceSoapClient.get_clients(client.RbhaId,
client.ClientId,
client.AhcccsId,
client.LastName,
client.FirstName,
"");//client.BirthDate.ToString()); //TODO: NEED TO FIX
// USE LINQ to go through the dataset to make it easily available for the Model to display on the View page
List<IClient> clients = (from c in dataSet.Tables[0].AsEnumerable()
select new Client()
{
RbhaId = c[5].ToString(),
ClientId = c[2].ToString(),
AhcccsId = c[6].ToString(),
LastName = c[0].ToString(), // Add another field called Sex M/F c[4]
FirstName = c[1].ToString(),
BirthDate = c[3].ToDateTime() //extension helper ToDateTime()
}).ToList<IClient>();
return clients;
}
Then in the Controller I'm doing this
IClient client = (IClient)TempData["Client"];
// Instantiate and instance of the repository
var repository = new Get_Client_Repository();
// Set a model object to return the dynamic list from repository method call passing in the parameter data
var model = repository.GetClient(client);
// Call the View up passing in the data from the list
return View(model);
Then in the View it is easy :
@model IEnumerable<CISOnlineMVC.DAL.IClient>
@{
ViewBag.Title = "CLIENT ALL INFORMATION";
}
<h2>CLIENT ALL INFORMATION</h2>
<table>
<tr>
<th></th>
<th>Last Name</th>
<th>First Name</th>
<th>Client ID</th>
<th>DOB</th>
<th>Gender</th>
<th>RBHA ID</th>
<th>AHCCCS ID</th>
</tr>
@foreach (var item in Model) {
<tr>
<td>
@Html.ActionLink("Select", "ClientDetails", "Cis", new { id = item.ClientId }, null) |
</td>
<td>
@item.LastName
</td>
<td>
@item.FirstName
</td>
<td>
@item.ClientId
</td>
<td>
@item.BirthDate
</td>
<td>
Gender @* ADD in*@
</td>
<td>
@item.RbhaId
</td>
<td>
@item.AhcccsId
</td>
</tr>
}
</table>

Problem. My stored Claws Mail messages are wrapped as follows, and I am trying to extract the Subject lines:
Subject: [SLC38A9 lysosomal arginine sensor; mTORC1 pathway] Key molecular
link in major cell growth pathway: Findings point to new potential
therapeutic target in pancreatic cancer [mTORC1 Activator SLC38A9 Is
Required to Efflux Essential Amino Acids from Lysosomes and Use Protein as
a Nutrient] [Re: Nutrient sensor in key growth-regulating metabolic pathway
identified [Lysosomal amino acid transporter SLC38A9 signals arginine
sufficiency to mTORC1]]
Message-ID: <[email protected]>
Per A2 in this thread, How to use sed/grep to extract text between two words? the first expression, below, "works" as long as the matched text does not contain a newline:
grep -o -P '(?<=Subject: ).*(?=molecular)' corpus/01
[SLC38A9 lysosomal arginine sensor; mTORC1 pathway] Key
However, despite trying numerous variants (.+?; /s; ...
), I could not get these to work:
grep -o -P '(?<=Subject: ).*(?=link)' corpus/01
grep -o -P '(?<=Subject: ).*(?=therapeutic)' corpus/01
etc.
Solution 1.
Per Extract text between two strings on different lines
sed -n '/Subject: /{:a;N;/Message-ID:/!ba; s/\n/ /g; s/\s\s*/ /g; s/.*Subject: \|Message-ID:.*//g;p}' corpus/01
which gives
[SLC38A9 lysosomal arginine sensor; mTORC1 pathway] Key molecular link in major cell growth pathway: Findings point to new potential therapeutic target in pancreatic cancer [mTORC1 Activator SLC38A9 Is Required to Efflux Essential Amino Acids from Lysosomes and Use Protein as a Nutrient] [Re: Nutrient sensor in key growth-regulating metabolic pathway identified [Lysosomal amino acid transporter SLC38A9 signals arginine sufficiency to mTORC1]]
Solution 2.*
Per How can I replace a newline (\n) using sed?
sed ':a;N;$!ba;s/\n/ /g' corpus/01
will replace newlines with a space.
Chaining that with A2 in How to use sed/grep to extract text between two words?, we get:
sed ':a;N;$!ba;s/\n/ /g' corpus/01 | grep -o -P '(?<=Subject: ).*(?=Message-ID:)'
which gives
[SLC38A9 lysosomal arginine sensor; mTORC1 pathway] Key molecular link in major cell growth pathway: Findings point to new potential therapeutic target in pancreatic cancer [mTORC1 Activator SLC38A9 Is Required to Efflux Essential Amino Acids from Lysosomes and Use Protein as a Nutrient] [Re: Nutrient sensor in key growth-regulating metabolic pathway identified [Lysosomal amino acid transporter SLC38A9 signals arginine sufficiency to mTORC1]]
This variant removes double spaces:
sed ':a;N;$!ba;s/\n/ /g; s/\s\s*/ /g' corpus/01 | grep -o -P '(?<=Subject: ).*(?=Message-ID:)'
giving
[SLC38A9 lysosomal arginine sensor; mTORC1 pathway] Key molecular link in major cell growth pathway: Findings point to new potential therapeutic target in pancreatic cancer [mTORC1 Activator SLC38A9 Is Required to Efflux Essential Amino Acids from Lysosomes and Use Protein as a Nutrient] [Re: Nutrient sensor in key growth-regulating metabolic pathway identified [Lysosomal amino acid transporter SLC38A9 signals arginine sufficiency to mTORC1]]
You have enabled CORS and enabled Access-Control-Allow-Origin : *
in the server.If still you get GET
method working and POST
method is not working then it might be because of the problem of Content-Type
and data
problem.
First AngularJS transmits data using Content-Type: application/json
which is not serialized natively by some of the web servers (notably PHP). For them we have to transmit the data as Content-Type: x-www-form-urlencoded
Example :-
$scope.formLoginPost = function () {
$http({
url: url,
method: "POST",
data: $.param({ 'username': $scope.username, 'Password': $scope.Password }),
headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
}).then(function (response) {
// success
console.log('success');
console.log("then : " + JSON.stringify(response));
}, function (response) { // optional
// failed
console.log('failed');
console.log(JSON.stringify(response));
});
};
Note : I am using $.params
to serialize the data to use Content-Type: x-www-form-urlencoded
. Alternatively you can use the following javascript function
function params(obj){
var str = "";
for (var key in obj) {
if (str != "") {
str += "&";
}
str += key + "=" + encodeURIComponent(obj[key]);
}
return str;
}
and use params({ 'username': $scope.username, 'Password': $scope.Password })
to serialize it as the Content-Type: x-www-form-urlencoded
requests only gets the POST data in username=john&Password=12345
form.
Works for WebView but seems to fail on URL.openStream()
. So you need to distinguish file:// protocols and handle them via AssetManager as suggested.
Wrap your AND logic in parenthesis, like this:
mysql_query("SELECT * FROM Drinks WHERE email='$Email' AND (date='$Date_Today' OR date='$Date_Yesterday' OR date='$Date_TwoDaysAgo' OR date='$Date_ThreeDaysAgo' OR date='$Date_FourDaysAgo' OR date='$Date_FiveDaysAgo' OR date='$Date_SixDaysAgo' OR date='$Date_SevenDaysAgo')");
This works if you want the element to span across the page like another navigation bar.
width: calc (width: 100% - width whatever else is off centering it)
For example if your side navigation bar is 200px:
width: calc(100% - 200px);
SortedSet has been added Since java 7 https://docs.oracle.com/javase/8/docs/api/java/util/SortedSet.html
inline-styles
in a document have the highest priority, so for example say if you want to change the color of a div
element to blue
, but you've an inline style
with a color
property set to red
<div style="font-size: 18px; color: red;">
Hello World, How Can I Change The Color To Blue?
</div>
div {
color: blue;
/* This Won't Work, As Inline Styles Have Color Red And As
Inline Styles Have Highest Priority, We Cannot Over Ride
The Color Using An Element Selector */
}
So, Should I Use jQuery/Javascript? - Answer Is NO
We can use element-attr
CSS Selector with !important
, note, !important
is important here, else it won't over ride the inline styles..
<div style="font-size: 30px; color: red;">
This is a test to see whether the inline styles can be over ridden with CSS?
</div>
div[style] {
font-size: 12px !important;
color: blue !important;
}
Note: Using
!important
ONLY will work here, but I've useddiv[style]
selector to specifically selectdiv
havingstyle
attribute
Yet another example...
from __future__ import print_function #Only for Python2
with open('file1.txt') as f1, open('file2.txt') as f2, open('outfile.txt', 'w') as outfile:
for line1, line2 in zip(f1, f2):
if line1 == line2:
print(line1, end='', file=outfile)
And if you want to eliminate common blank lines, just change the if statement to:
if line1.strip() and line1 == line2:
.strip()
removes all leading and trailing whitespace, so if that's all that's on a line, it will become an empty string ""
, which is considered false.
SHA-1 produces a 160-bit message (20 bytes), too large to be stored in an int
or long
value. As Ralph suggests, you could use BigInteger.
To get a (less-secure) int hash, you could return the hash code of the returned byte array.
Alternatively, if you don't really need SHA at all, you could just use the UUID's String hash code.
ul>li
selects all li
that are a direct child of ul
whereas ul li
selects all li
that are anywhere within (descending as deep as you like) a ul
For HTML:
<ul>
<li><span><a href='#'>Something</a></span></li>
<li><a href='#'>or Other</a></li>
</ul>
And CSS:
li a{ color: green; }
li>a{ color: red; }
The colour of Something
will remain green but or Other
will be red
Part 2, you should write the rule to be appropriate to the situation, I think the speed difference would be incredibly small, and probably overshadowed by the extra characters involved in writing more code, and definitely overshadowed by the time taken by the developer to think about it.
However, as a rule of thumb, the more specific you are with your rules, the faster the CSS engines can locate the DOM elements you want to apply it to, so I expect li>a
is faster than li a
as the DOM search can be cut short earlier. It also means that nested anchors are not styled with that rule, is that what you want? <~~ much more pertinent question.
It's simple:
array = []
will set array
to be an empty list. (They're called lists in Python, by the way, not arrays)
If that doesn't work for you, edit your question to include a code sample that demonstrates your problem.

FURTHER QUESTION: Wrong information?
If you check memory usage with the ps
command, you will see that the java process consumes much more...
ps -eo size,pid,user,command --sort -size | egrep -i "*/bin/java *" | egrep -v grep | awk '{ hr=$1/1024 ; printf("%.2f MB ",hr) } { for ( x=4 ; x<=NF ; x++ ) { printf("%s ",$x) } print "" }' | cut -d "" -f2 | cut -d "-" -f1
UPDATE (2021-02-16):
According to the reference below (and @Till Schäfer comment) "ps can show total reserved memory from OS" (adapted) and "jstat can show used space of heap and stack" (adapted). So, we see a difference between what is pointed out by the ps
command and the jstat
command.
According to our understanding, the most "realistic" information would be the ps
output since we will have an effective response of how much of the system's memory is compromised. The command jstat
serves for a more detailed analysis regarding the java performance in the consumption of reserved memory from OS.
[Ref.: http://www.openkb.info/2014/06/how-to-check-java-memory-usage.html ]
(In Kotlin) If you are going to put the answer into a TextView or something you can instead use a string resource:
<string name="time">%02d:%02d</string>
And then you can use this String resource to then set the text at run time using:
private fun setTime(time: Int) {
val hour = time / 60
val min = time % 60
main_time.text = getString(R.string.time, hour, min)
}
You'll probably find you're setting the date to Feb 31, 2009 (if today is Jan 31) and Javascript automagically rolls that into the early part of March.
Check the day of the month, I'd expect it to be 1, 2 or 3. If it's not the same as before you added a month, roll back by one day until the month changes again.
That way, the day "last day of Jan" becomes "last day of Feb".
EDIT:
Ronald, based on your comments to other answers, you might want to steer clear of edge-case behavior such as "what happens when I try to make Feb 30" or "what happens when I try to make 2009/13/07 (yyyy/mm/dd)" (that last one might still be a problem even for my solution, so you should test it).
Instead, I would explicitly code for the possibilities. Since you don't care about the day of the month (you just want the year and month to be correct for next month), something like this should suffice:
var now = new Date();
if (now.getMonth() == 11) {
var current = new Date(now.getFullYear() + 1, 0, 1);
} else {
var current = new Date(now.getFullYear(), now.getMonth() + 1, 1);
}
That gives you Jan 1 the following year for any day in December and the first day of the following month for any other day. More code, I know, but I've long since grown tired of coding tricks for efficiency, preferring readability unless there's a clear requirement to do otherwise.

Since you've already looked into strtok
just continue down the same path and split your string using space (' '
) as a delimiter, then use something as realloc
to increase the size of the array containing the elements to be passed to execvp
.
See the below example, but keep in mind that strtok
will modify the string passed to it. If you don't want this to happen you are required to make a copy of the original string, using strcpy
or similar function.
char str[]= "ls -l";
char ** res = NULL;
char * p = strtok (str, " ");
int n_spaces = 0, i;
/* split string and append tokens to 'res' */
while (p) {
res = realloc (res, sizeof (char*) * ++n_spaces);
if (res == NULL)
exit (-1); /* memory allocation failed */
res[n_spaces-1] = p;
p = strtok (NULL, " ");
}
/* realloc one extra element for the last NULL */
res = realloc (res, sizeof (char*) * (n_spaces+1));
res[n_spaces] = 0;
/* print the result */
for (i = 0; i < (n_spaces+1); ++i)
printf ("res[%d] = %s\n", i, res[i]);
/* free the memory allocated */
free (res);
res[0] = ls
res[1] = -l
res[2] = (null)

In general software terms, an "artifact" is something produced by the software development process, whether it be software related documentation or an executable file.
In Maven terminology, the artifact is the resulting output of the maven build, generally a jar
or war
or other executable file. Artifacts in maven are identified by a coordinate system of groupId, artifactId, and version. Maven uses the groupId
, artifactId
, and version
to identify dependencies (usually other jar files) needed to build and run your code.
STR_TO_DATE allows you to do this, and it has a format argument.

For parent-child communication, simply pass props.
Use state to store the data your current page needs in your controller-view.
Use props to pass data & event handlers down to your child components.
These lists should help guide you when working with data in your components.
Props
State
For communication between two components that don't have a parent-child relationship, you can set up your own global event system. Subscribe to events in componentDidMount(), unsubscribe in componentWillUnmount(), and call setState() when you receive an event. Flux pattern is one of the possible ways to arrange this. - https://facebook.github.io/react/tips/communicate-between-components.html
What Components Should Have State?
Most of your components should simply take some data from props and render it. However, sometimes you need to respond to user input, a server request or the passage of time. For this you use state.
Try to keep as many of your components as possible stateless. By doing this you'll isolate the state to its most logical place and minimize redundancy, making it easier to reason about your application.
A common pattern is to create several stateless components that just render data, and have a stateful component above them in the hierarchy that passes its state to its children via props. The stateful component encapsulates all of the interaction logic, while the stateless components take care of rendering data in a declarative way. - https://facebook.github.io/react/docs/interactivity-and-dynamic-uis.html#what-components-should-have-state
What Should Go in State?
State should contain data that a component's event handlers may change to trigger a UI update. In real apps this data tends to be very small and JSON-serializable. When building a stateful component, think about the minimal possible representation of its state, and only store those properties in this.state. Inside of render() simply compute any other information you need based on this state. You'll find that thinking about and writing applications in this way tends to lead to the most correct application, since adding redundant or computed values to state means that you need to explicitly keep them in sync rather than rely on React computing them for you. - https://facebook.github.io/react/docs/interactivity-and-dynamic-uis.html#what-should-go-in-state

Process
Each process provides the resources needed to execute a program. A process has a virtual address space, executable code, open handles to system objects, a security context, a unique process identifier, environment variables, a priority class, minimum and maximum working set sizes, and at least one thread of execution. Each process is started with a single thread, often called the primary thread, but can create additional threads from any of its threads.
Thread
A thread is an entity within a process that can be scheduled for execution. All threads of a process share its virtual address space and system resources. In addition, each thread maintains exception handlers, a scheduling priority, thread local storage, a unique thread identifier, and a set of structures the system will use to save the thread context until it is scheduled. The thread context includes the thread's set of machine registers, the kernel stack, a thread environment block, and a user stack in the address space of the thread's process. Threads can also have their own security context, which can be used for impersonating clients.
This information was found on Microsoft Docs here: About Processes and Threads
Microsoft Windows supports preemptive multitasking, which creates the effect of simultaneous execution of multiple threads from multiple processes. On a multiprocessor computer, the system can simultaneously execute as many threads as there are processors on the computer.
Here is an example:
#include"stdio.h"
#include"conio.h"
void main()
{
int rm, vivek;
clrscr();
printf("Enter any numbers\t(E.g., 1, 2, 5");
scanf("%d", &rm); // rm = 5(0101) << 2 (two step add zero's), so the value is 10100
printf("This left shift value%d=%d", rm, rm<<4);
printf("This right shift value%d=%d", rm, rm>>2);
getch();
}
Try this code.
public void send (String fileName) {
String SFTPHOST = "host:IP";
int SFTPPORT = 22;
String SFTPUSER = "username";
String SFTPPASS = "password";
String SFTPWORKINGDIR = "file/to/transfer";
Session session = null;
Channel channel = null;
ChannelSftp channelSftp = null;
System.out.println("preparing the host information for sftp.");
try {
JSch jsch = new JSch();
session = jsch.getSession(SFTPUSER, SFTPHOST, SFTPPORT);
session.setPassword(SFTPPASS);
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.connect();
System.out.println("Host connected.");
channel = session.openChannel("sftp");
channel.connect();
System.out.println("sftp channel opened and connected.");
channelSftp = (ChannelSftp) channel;
channelSftp.cd(SFTPWORKINGDIR);
File f = new File(fileName);
channelSftp.put(new FileInputStream(f), f.getName());
log.info("File transfered successfully to host.");
} catch (Exception ex) {
System.out.println("Exception found while tranfer the response.");
} finally {
channelSftp.exit();
System.out.println("sftp Channel exited.");
channel.disconnect();
System.out.println("Channel disconnected.");
session.disconnect();
System.out.println("Host Session disconnected.");
}
}
Static constructor
called only the first instance of the class created. and used to perform a particular action that needs to be performed only once in the life cycle of the class.
You're not using splice correctly:
arr.splice(4, 1)
this will remove 1 item at index 4. see here
I think you want to use slice:
arr.slice(0,5)
this will return elements in position 0 through 4.
This assumes all the rest of your code (cookies etc) works correctly
Often times configmaps or secrets are injected as configuration files in containers. Depending on the application a restart may be required should those be updated with a subsequent helm upgrade
, but if the deployment spec itself didn't change the application keeps running with the old configuration resulting in an inconsistent deployment.
The sha256sum
function can be used together with the include
function to ensure a deployments template section is updated if another spec changes:
kind: Deployment
spec:
template:
metadata:
annotations:
checksum/config: {{ include (print $.Template.BasePath "/secret.yaml") . | sha256sum }}
[...]
In my case, for some reasons, $.Template.BasePath
didn't work but $.Chart.Name
does:
spec:
replicas: 1
template:
metadata:
labels:
app: admin-app
annotations:
checksum/config: {{ include (print $.Chart.Name "/templates/" $.Chart.Name "-configmap.yaml") . | sha256sum }}
You can use following methods to get current date in milliseconds.
[[NSDate date] timeIntervalSince1970];
OR
double CurrentTime = CACurrentMediaTime();
Why are you specifying myFile
there?
Git revert reverts the commit(s) that you specify.
git revert HEAD~2
reverts the HEAD~2
commit
git revert HEAD~2 myfile
reverts HEAD~2
AND myFile
I take myFile
is a file that you want to revert? In that case use
git checkout HEAD~2 -- myFile
I am using IIS and mysql (directly downloaded, without wamp or xampp) My php was installed in c:\php I was getting the error of "call to undefined function mysql_connect()" For me the change of extension_dir worked. This is what I did. In the php.ini, Originally, I had this line
; On windows: extension_dir = "ext"
I changed it to:
; On windows: extension_dir = "C:\php\ext"
And it worked. Of course, I did the other things also like uncommenting the dll extensions etc, as explained in others remarks.
Key/index : A key is an aspect of a LOGICAL database design, an index is an aspect of a PHYSICAL database design. A key corresponds to an integrity constraint, an index is a technique of physically recording values that can be usefully applied when enforcing those constraints.
Primary/foreign : A "primary" key is a set of attributes whose values must form a combination that is unique in the entire table. There can be more than one such set (> 1 key), and the word "primary" is a remnant from the earlier days when the designer was then forced to choose one of those multiple keys as being "the most important/relevant one". The reason for this was primarily in combination with foreign keys :
Like a "primary" key, a "foreign" key is also a set of attributes. The values of these attributes must form a combination that is an existing primary key value in the referenced table. I don't know exactly how strict this rule still applies in SQL today. The terminology has remained anyway.
Unique : keyword used to indicate that an index cannot accept duplicate entries. Unique indexes are obviously an excellent means to enforce primary keys. To the extent that the word 'unique' is used in contexts of LOGICAL design, it is superfluous, sloppy, unnecessary and confusing. Keys (primary keys, that is) are unique by definition.
For temporary internal files their are 2 options
1.
File file;
file = File.createTempFile(filename, null, this.getCacheDir());
2.
File file
file = new File(this.getCacheDir(), filename);
Both options adds files in the applications cache directory and thus can be cleared to make space as required but option 1 will add a random number on the end of the filename to keep files unique. It will also add a file extension which is .tmp
by default, but it can be set to anything via the use of the 2nd parameter. The use of the random number means despite specifying a filename it doesn't stay the same as the number is added along with the suffix/file extension (.tmp
by default) e.g you specify your filename as internal_file
and comes out as internal_file1456345.tmp
. Whereas you can specify the extension you can't specify the number that is added. You can however find the filename it generates via file.getName();
, but you would need to store it somewhere so you can use it whenever you wanted for example to delete or read the file. Therefore for this reason I prefer the 2nd option as the filename you specify is the filename that is created.
Strings in C are represented as arrays of characters.
char *p = "String";
You are declaring a pointer that points to a string stored some where in your program (modifying this string is undefined behavior) according to the C programming language 2 ed.
char p2[] = "String";
You are declaring an array of char initialized with the string "String" leaving to the compiler the job to count the size of the array.
char p3[5] = "String";
You are declaring an array of size 5 and initializing it with "String". This is an error be cause "String" don't fit in 5 elements.
char p3[7] = "String";
is the correct declaration ('\0' is the terminating character in c strings).
Implement INotifyPropertyChanged
in your class.
Specify a callback in the property metadata when you register the dependency property.
In the callback, raise the PropertyChanged
event.
Adding the callback:
public static DependencyProperty FirstProperty = DependencyProperty.Register(
"First",
typeof(string),
typeof(MyType),
new FrameworkPropertyMetadata(
false,
new PropertyChangedCallback(OnFirstPropertyChanged)));
Raising PropertyChanged
in the callback:
private static void OnFirstPropertyChanged(
DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
PropertyChangedEventHandler h = PropertyChanged;
if (h != null)
{
h(sender, new PropertyChangedEventArgs("Second"));
}
}
JackDB, a database client in your web browser, makes this really easy. Especially if you're on Heroku.
It lets you connect to remote databases and run SQL queries on them.
Source
(source: jackdb.com)
Once your DB is connected, you can run a query and export to CSV or TXT (see bottom right).
Note: I'm in no way affiliated with JackDB. I currently use their free services and think it's a great product.
Starting from C++23 you can use std::string::contains
#include <string>
const auto haystack = std::string("haystack with needles");
const auto needle = std::string("needle");
if (haystack.contains(needle))
{
// found!
}
a = ['it']
b = ['was']
c = ['annoying']
a.extend(b)
a.extend(c)
# a now equals ['it', 'was', 'annoying']
Write a single function and call it for both of them.
function yourHandler(e){
alert( 'something happened!' );
}
jQuery(':input').change(yourHandler).keyup(yourHandler);
The change() and keyup() event registration functions return the original set, so they can be chained.
It's been a while since this question was asked, but maybe now you can forego Bootstrap altogether and use CSS Grid! (it's simpler, neater, more flexible and faster). See this cool article: Stop using Bootstrap — create a practical CSS Grid template for your component based UI
Convert timeofday to string to use indexOf
var timeofday = new Date().getHours() + (new Date().getMinutes()) / 60;
console.log(typeof(timeofday)) // for testing will log number
function timeD2C(time) { // Converts 11.5 (decimal) to 11:30 (colon)
var pos = time.indexOf('.');
var hrs = time.substr(1, pos - 1);
var min = (time.substr(pos, 2)) * 60;
if (hrs > 11) {
hrs = (hrs - 12) + ":" + min + " PM";
} else {
hrs += ":" + min + " AM";
}
return hrs;
}
// "" for typecasting to string
document.getElementById("oset").innerHTML = timeD2C(""+timeofday);
Solution 2
use toString()
to convert to string
document.getElementById("oset").innerHTML = timeD2C(timeofday.toString());
After converting your varchar2
date to a true date
datatype, then convert back to varchar2
with the desired mask:
to_char(to_date('01/02/2012','MM/DD/YYYY'),'WW')
If you want the week number in a number
datatype, you can wrap the statement in to_number()
:
to_number(to_char(to_date('01/02/2012','MM/DD/YYYY'),'WW'))
However, you have several week number options to consider:
WW Week of year (1-53) where week 1 starts on the first day of the year and continues to the seventh day of the year.
W Week of month (1-5) where week 1 starts on the first day of the month and ends on the seventh.
IW Week of year (1-52 or 1-53) based on the ISO standard.
overflow-x: hidden;
would hide any thing on the x-axis that goes outside of the element, so there would be no need for the horizontal scrollbar and it get removed.
overflow-y: hidden;
would hide any thing on the y-axis that goes outside of the element, so there would be no need for the vertical scrollbar and it get removed.
overflow: hidden;
would remove both scrollbars
Sometimes you have a custom background, in that cases a better solution is use android:foreground="?selectableItemBackground"
If you want ripple effect with rounded corners and custom background you can use this:
background_ripple.xml
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android" android:color="@color/ripple_color">
<item android:id="@android:id/mask">
<shape android:shape="rectangle">
<solid android:color="@android:color/white" />
<corners android:radius="5dp" />
</shape>
</item>
<item android:id="@android:id/background">
<shape android:shape="rectangle">
<solid android:color="@android:color/white" />
<corners android:radius="5dp" />
</shape>
</item>
layout.xml
<Button
android:id="@+id/btn_play"
android:background="@drawable/background_ripple"
app:backgroundTint="@color/colorPrimary"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/play_now" />

First off, when you create a "bare repository", you're not going to be doing any work with it (it doesn't contain a working copy, so the git branch
command is not useful).
Now, the reason you wouldn't have a master
branch even after doing a git init
is that there are no commits: when you create your first commit, you will then have a master
branch.
I just had the same problem and I found out that if you are running your container with the -t
and -d
flag, it keeps running.
docker run -td <image>
Here is what the flags do (according to docker run --help
):
-d, --detach=false Run container in background and print container ID
-t, --tty=false Allocate a pseudo-TTY
The most important one is the -t
flag. -d
just lets you run the container in the background.
If you are using the default theme. Just goto Preferences-> Default File Preferences A new tab pops up. At about line number you could see the font [font-name] [font-size]
Edit the font-size according to your wish and save.
Once you're in the directory, just run it as ./myScript.sh
Using the PHPExcel library, the following code will do.
require_once dirname(__FILE__) . '/../Classes/PHPExcel/IOFactory.php';
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objReader->setReadDataOnly(true); //optional
$objPHPExcel = $objReader->load(__DIR__.'/YourExcelFile.xlsx');
$objWorksheet = $objPHPExcel->getActiveSheet();
$i=1;
foreach ($objWorksheet->getRowIterator() as $row) {
$column_A_Value = $objPHPExcel->getActiveSheet()->getCell("A$i")->getValue();//column A
//you can add your own columns B, C, D etc.
//inset $column_A_Value value in DB query here
$i++;
}
You can try the following:
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog fDialog = new OpenFileDialog();
fDialog.Title = "Select file to be upload";
fDialog.Filter = "All Files|*.*";
// fDialog.Filter = "PDF Files|*.pdf";
if (fDialog.ShowDialog() == DialogResult.OK)
{
textBox1.Text = fDialog.FileName.ToString();
}
}
