It is now possible to use Wireshark directly to capture Android emulator traffic. There is an extcap plugin called androiddump which makes it possible. You need to have a tcpdump
executable in the system image running on the emulator (most current images have it, tested with API 24 and API 27 images) and adbd
running as root on the host (just run adb root
). In the list of the available interfaces in Wireshark (Qt version only, the deprecated GTK+ doesn't have it) or the list shown with tshark -D
there should be several Android interfaces allowing to sniff Bluetooth, Logcat, or Wifi traffic, e.g.:
android-wifi-tcpdump-emulator-5554 (Android WiFi Android_SDK_built_for_x86 emulator-5554)
On Nougat(7.0) Android version run adb shell pm list packages
to list the packages installed on the device.
Then run adb shell pm path your-package-name
to show the path of the apk.
After use adb to copy the package to Downloads adb shell cp /data/app/com.test-1/base.apk /storage/emulated/0/Download
.
Then pull the apk from Downloads to your machine by running adb pull /storage/emulated/0/Download/base.apk
.
You can use this way either :
Add this line to your recyclerView xml file :
android:nestedScrollingEnabled="false"
Or in java code :
RecyclerView.setNestedScrollingEnabled(false);
Hope this helped .

Please note the instructions have changed since this question was asked 2 yrs ago.
So on Newer versions of Android and Chrome for Android. You need to use this.
https://developers.google.com/web/tools/setup/remote-debugging/remote-debugging?hl=en
Original Answer:
I have the S3 and it works fine. I have found that a common mistake is not enabling USB Debugging in Chrome mobile. Not only do you have to enable USB debugging on the device itself under developer options but you have to go to the Chrome Browser on your phone and enable it in the settings there too.
Try this with the SDK
Enable port forwarding on your computer by doing the following command below
C:\adb forward tcp:9222 localabstract:chrome_devtools_remote
Go to http://localhost:9222
in Chrome on your Computer
TroubleShooting:
If you get command not found
when trying to run ADB
, make sure Platform-Tools is in your path or just use the whole path to your SDK and run it
C:\path-to-SDK\platform-tools\adb forward tcp:9222 localabstract:chrome_devtools_remote
If you get "device not found
", then run adb kill-server
and then try again.
It's not enough to have just compile project("xy")
dependency.
You need to configure root project to include all modules (or to call them subprojects but that might not be correct word here).
Create a settings.gradle file in the root of your project and add this:
include ':progressfragment'
to that file. Then sync Gradle and it should work.
Also one interesting side note: If you add ':unexistingProject' in settings.gradle (project that you haven't created yet), Gradle will create folder for this project after sync (at least in Android studio this is how it behaves). So, to avoid errors with settings.gradle when you create project from existing files, first add that line to file, sync and then put existing code in created folder. Unwanted behavior arising from this might be that if you delete the project folder and then sync folder will come back empty because Gradle sync recreated it since it is still listed in settings.gradle.
You can pass an enum through as a string.
public enum CountType {
ONE,
TWO,
THREE
}
private CountType count;
count = ONE;
String countString = count.name();
CountType countToo = CountType.valueOf(countString);
Given strings are supported you should be able to pass the value of the enum around with no problem.
if u are getting errors even after downloading newest SDK and Android Studio I am a newbie: What i did was 1. Download the recent SDK (i was ) 2.Open file-Project structure (ctrl+alt+shift+S) 3. In modules select app 4.In properties tab..change compile sdk version to api 23 Android 6.0 marshmallow(latest)
make sure compile adk versionand buildtools are of same version(23)
Hope it helps someone so that he wont suffer like i did for these couple of days.
you can got Current latlng using this

As far as I know, F11 or F12 doesn't work, and nor does Right Ctrl + F12.
Hit Left Ctrl + F12, or Home, or PageUp, (not NUMPAD 7 or NUMPAD 9 like the website says) to rotate the emulator.
don't use USB 3.0 ports for connection beetwen PC and Android phone!

In firebase-messaging:17.1.0
and newer the FirebaseInstanceIdService is deprecated, you can get the onNewToken
on the FirebaseMessagingService
class as explained on https://stackoverflow.com/a/51475096/1351469
But if you want to just get the token any time, then now you can do it like this:
FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener( this.getActivity(), new OnSuccessListener<InstanceIdResult>() {
@Override
public void onSuccess(InstanceIdResult instanceIdResult) {
String newToken = instanceIdResult.getToken();
Log.e("newToken",newToken);
}
});
You can get the time & date seperately from Calendar.
// You can pass time zone and Local to getInstance() as parameter
Calendar calendar = Calendar.getInstance();
int currentHour = calendar.get(Calendar.HOUR_OF_DAY);
int currentMinute = calendar.get(Calendar.MINUTE);
int second = calendar.get(Calendar.SECOND);
int date = calendar.get(Calendar.DAY_OF_MONTH);
int month = calendar.get(Calendar.MONTH);
int year = calendar.get(Calendar.YEAR);
No one has explicitly mentioned that weightSum
is a particular XML attribute for LinearLayout
.
I believe this would be helpful to anyone who was confused at first as I was, looking for weightSum
in the ConstraintLayout
documentation.
Why don't you try to grep the return of your command ? Something like :
adb devices -l | grep 123abc12
It should return only the line you want to.
Following are some key points :
Conclusion
You can just use the View.setId(integer)
for this. In the XML, even though you're setting a String id, this gets converted into an integer. Due to this, you can use any (positive) Integer for the Views
you add programmatically.
According to
View
documentationThe identifier does not have to be unique in this view's hierarchy. The identifier should be a positive number.
So you can use any positive integer you like, but in this case there can be some views with equivalent id's. If you want to search for some view in hierarchy calling to setTag with some key objects may be handy.
Credits to this answer.
you can put the first cell in your array to be empty({"","some","some",...}) and do nothing if the position is 0;
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if(position>0) {
label.setText(MainActivity.questions[position - 1]);
}
}
spinnerType = (AppCompatSpinner) findViewById(R.id.account_type);
spinnerType.setPrompt("Select Type");
spinnerType.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
TypeItem clickedItem = (TypeItem) parent.getItemAtPosition(position);
String TypeName = clickedItem.getTypeName();
Toast.makeText(AddAccount.this, TypeName + " selected", Toast.LENGTH_SHORT).show();
}

You can find the default Android menu icons here - link is broken now.
Update: You can find Material Design icons here.
I have created a simple, lightweight class (about 260 LoC) that extends the standard android.util.Log implementation with file based logging:
Every log message is logged via android.util.Log and also written to a text file on the device.
You can find it on github:
https://github.com/volkerv/FileLog
if your SQL query is this
SELECT id,name,roll FROM student WHERE name='Amit' AND roll='7'
then rawQuery will be
String query="SELECT id, name, roll FROM student WHERE name = ? AND roll = ?";
String[] selectionArgs = {"Amit","7"}
db.rawQuery(query, selectionArgs);
In my case, I pressed Deny unfortunately during first time installation. So I was getting INSTALL_FAILED_USER_RESTRICTED.
You can get modify this permission for app under permissions.
Settings->Permissions->Install via USB->{Your App}
You should have enabled below options too.
Settings->Additional Settings->Privacy->Unknown Sources
Settings->Additional Settings->Developer Options->Install via USB
If you're using android studio an item is under your strings.xml
<string name="app_name">BareBoneProject</string>
It's better to change the name here because you might have used this string somewhere.Or maybe a library or something has used it.That's it.Just build and run and you'll get new name.Remember this won't change the package name or anything else.
Here is my solution for mac users I think it work for window also:
First go to your Android Studio toolbar
Build > Make Project (while you guys are online let it to download the files) and then
Build > Compile Module "your app name is shown here" (still online let the files are
download and finish) and then
Run your app that is done it will launch your emulator and configure it then run it!
That is it!!! Happy Coding guys!!!!!!!
import org.apache.commons.lang.math.NumberUtils;
This will handle null
NumberUtils.createLong(String)
String myString = getString(R.string.mystring);
easy way
In your case you need to
android:scaleType
to fitXY
Below is an example:
<ImageView
android:id="@+id/photo"
android:layout_width="200dp"
android:layout_height="100dp"
android:src="@drawable/iclauncher"
android:scaleType="fitXY"/>
For more information regarding ImageView scaleType please refer to the developer website.
setDatabasePath() method was deprecated in API level 19. I advise you to use storage locale like this:
webView.getSettings().setDomStorageEnabled(true);
webView.getSettings().setDatabaseEnabled(true);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
webView.getSettings().setDatabasePath("/data/data/" + webView.getContext().getPackageName() + "/databases/");
}
Two and half years after the OP posed his question, this issue is still, well, still an issue. It's obvious Google's priority on this isn't particularly high, so rather than find a fix, I found a workaround. The big breakthrough for me was finding out what the real cause of the problem was (see the accepted answer in this post ). Once it was apparent that the issue was that any active pages are not properly refreshed, my workaround was obvious:
In my Fragment (the pages):
In my Activity, where I do the loading of the pages:
After this, when you reload a second set of pages, the bug will still cause some to display the old data. However, they will now be refreshed and you will see the new data - your users won't know the page was ever incorrect because this refreshing will happen before they see the page.
Hope this helps someone!
It's an old question, but still active as there is no explicit Android feature. And the guys from facebook found a work around - somehow. Today, I found a way that works for me. Not perfect (see remarks at the end of this answer) but it works!
Main idea is, that I update the icon of my app's shortcut, created by the launcher on my home screen. When I want to change something on the shortcut-icon, I remove it first and recreate it with a new bitmap.
Here is the code. It has a button increment
. When pressed, the shortcut is replaced with one that has a new counting number.
First you need these two permissions in your manifest:
<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />
<uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" />
Then you need this two methods for installing and uninstalling shortcuts. The shortcutAdd
method creates a bitmap with a number in it. This is just to demonstrate that it actually changes. You probably want to change that part with something, you want in your app.
private void shortcutAdd(String name, int number) {
// Intent to be send, when shortcut is pressed by user ("launched")
Intent shortcutIntent = new Intent(getApplicationContext(), Play.class);
shortcutIntent.setAction(Constants.ACTION_PLAY);
// Create bitmap with number in it -> very default. You probably want to give it a more stylish look
Bitmap bitmap = Bitmap.createBitmap(100, 100, Bitmap.Config.ARGB_8888);
Paint paint = new Paint();
paint.setColor(0xFF808080); // gray
paint.setTextAlign(Paint.Align.CENTER);
paint.setTextSize(50);
new Canvas(bitmap).drawText(""+number, 50, 50, paint);
((ImageView) findViewById(R.id.icon)).setImageBitmap(bitmap);
// Decorate the shortcut
Intent addIntent = new Intent();
addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, name);
addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON, bitmap);
// Inform launcher to create shortcut
addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
getApplicationContext().sendBroadcast(addIntent);
}
private void shortcutDel(String name) {
// Intent to be send, when shortcut is pressed by user ("launched")
Intent shortcutIntent = new Intent(getApplicationContext(), Play.class);
shortcutIntent.setAction(Constants.ACTION_PLAY);
// Decorate the shortcut
Intent delIntent = new Intent();
delIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
delIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, name);
// Inform launcher to remove shortcut
delIntent.setAction("com.android.launcher.action.UNINSTALL_SHORTCUT");
getApplicationContext().sendBroadcast(delIntent);
}
And finally, here are two listener to add the first shortcut and update the shortcut with an incrementing counter.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
findViewById(R.id.add).setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
shortcutAdd("changeIt!", count);
}
});
findViewById(R.id.increment).setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
shortcutDel("changeIt!");
count++;
shortcutAdd("changeIt!", count);
}
});
}
Remarks:
This way works also if your App controls more shortcuts on the home screen, e.g. with different extra's in the Intent
. They just need different names so that the right one is uninstalled and reinstalled.
The programmatical handling of shortcuts in Android is a well known, widely used but not officially supported Android feature. It seems to work on the default launcher and I never tried it anywhere else. So dont blame me, when you get this user-emails "It does not work on my XYZ, double rooted, super blasted phone"
The launcher writes a Toast
when a shortcut was installad and one when a shortcut was uninstalled. So I get two Toast
s every time I change the icon. This is not perfect, but well, as long as the rest of my app is perfect...
allprojects {

This are the steps :
I haven't tried for eclipse but it might work for that also.
ok just so you know there is a program out there that's called DroidDraw. It can help you draw objects and try them one on top of the other. I tried your solution but I had animation under the smaller image so that didn't work. But then I tried to place one image in a relative layout that's suppose to be under first and then on top of that I drew the other image that is suppose to overlay and everything worked great. So RelativeLayout, DroidDraw and you are good to go :) Simple, no any kind of jiggery pockery :) and here is a bit of code for ya:
The logo is going to be on top of shazam background image.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="@+id/widget30"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
>
<ImageView
android:id="@+id/widget39"
android:layout_width="219px"
android:layout_height="225px"
android:src="@drawable/shazam_bkgd"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
>
</ImageView>
<ImageView
android:id="@+id/widget37"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/shazam_logo"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
>
</ImageView>
</RelativeLayout>
Use assets folder.
sample code:
InputStream is = null;
try {
is = this.getResources().getAssets().open("test/sample.png");
} catch (IOException e) {
;
}
image = BitmapFactory.decodeStream(is);
If your minimum SDK is 23 or upper you could use this:
View childView = findViewById(R.id.your_view_id_in_the_scroll_view)
if(childView != null){
scrollview.post(() -> scrollview.scrollToDescendant(childView));
}
call this method in onCreate
Snackbar snack = Snackbar.make(
(((Activity) context).findViewById(android.R.id.content)),
message + "", Snackbar.LENGTH_SHORT);
snack.setDuration(Snackbar.LENGTH_INDEFINITE);//change Duration as you need
//snack.setAction(actionButton, new View.OnClickListener());//add your own listener
View view = snack.getView();
TextView tv = (TextView) view
.findViewById(android.support.design.R.id.snackbar_text);
tv.setTextColor(Color.WHITE);//change textColor
TextView tvAction = (TextView) view
.findViewById(android.support.design.R.id.snackbar_action);
tvAction.setTextSize(16);
tvAction.setTextColor(Color.WHITE);
snack.show();
To customize tool bar style, first create tool bar custom style inheriting Widget.AppCompat.Toolbar, override properties and then add it to custom app theme as shown below, see http://www.zoftino.com/android-toolbar-tutorial for more information tool bar and styles.
<style name="MyAppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="toolbarStyle">@style/MyToolBarStyle</item>
</style>
<style name="MyToolBarStyle" parent="Widget.AppCompat.Toolbar">
<item name="android:background">#80deea</item>
<item name="titleTextAppearance">@style/MyTitleTextAppearance</item>
<item name="subtitleTextAppearance">@style/MySubTitleTextAppearance</item>
</style>
<style name="MyTitleTextAppearance" parent="TextAppearance.Widget.AppCompat.Toolbar.Title">
<item name="android:textSize">35dp</item>
<item name="android:textColor">#ff3d00</item>
</style>
<style name="MySubTitleTextAppearance" parent="TextAppearance.Widget.AppCompat.Toolbar.Subtitle">
<item name="android:textSize">30dp</item>
<item name="android:textColor">#1976d2</item>
</style>
In the AndroidManifest.xml file, for each activity you want to lock add the last screenOrientation
line:
android:label="@string/app_name"
android:name=".Login"
android:screenOrientation="portrait" >
Or android:screenOrientation="landscape".
I had a simular issue and resolved it using android:adjustViewBounds="true"
on the ImageView.
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:contentDescription="@string/banner_alt"
android:src="@drawable/banner_portrait" />
There is a new Gradle task called "cleanBuildCache" just run this task clean the cache then re-build the project.
In the latest version of the SDK, you would use the setBackgroundResource
method.
public void onClick(View v) {
if(v == ButtonName) {
ButtonName.setBackgroundResource(R.drawable.ImageResource);
}
}
onProgressChanged() should be called on every progress changed, not just on first and last touch (that why you have onStartTrackingTouch() and onStopTrackingTouch() methods).
Make sure that your SeekBar have more than 1 value, that is to say your MAX>=3.
In your onCreate:
yourSeekBar=(SeekBar) findViewById(R.id.yourSeekBar);
yourSeekBar.setOnSeekBarChangeListener(new yourListener());
Your listener:
private class yourListener implements SeekBar.OnSeekBarChangeListener {
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
// Log the progress
Log.d("DEBUG", "Progress is: "+progress);
//set textView's text
yourTextView.setText(""+progress);
}
public void onStartTrackingTouch(SeekBar seekBar) {}
public void onStopTrackingTouch(SeekBar seekBar) {}
}
Please share some code and the Log results for furter help.
I think I found the answer. Let me tell what I have done in simple words:
Suppose I have two activities, activity1 and activity2 and I am navigating from activity1 to activity2 (I have done some works in activity2) and again back to activity 1 by clicking on a button in activity1. Now at this stage I wanted to go back to activity2 and I want to see my activity2 in the same condition when I last left activity2.
For the above scenario what I have done is that in the manifest I made some changes like this:
<activity android:name=".activity2"
android:alwaysRetainTaskState="true"
android:launchMode="singleInstance">
</activity>
And in the activity1 on the button click event I have done like this:
Intent intent = new Intent();
intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
intent.setClassName(this,"com.mainscreen.activity2");
startActivity(intent);
And in activity2 on button click event I have done like this:
Intent intent=new Intent();
intent.setClassName(this,"com.mainscreen.activity1");
startActivity(intent);
Now what will happen is that whatever the changes we have made in the activity2 will not be lost, and we can view activity2 in the same state as we left previously.
I believe this is the answer and this works fine for me. Correct me if I am wrong.
I had this problem suddenly crop up in Windows 7 with my Nexus One - somehow the USB drivers had been uninstalled. I ran android-sdk/SDK Manager.exe, checked Extras/Google USB Driver and installed it. Then I unplugged the phone and plugged it back in, and ran "adb devices" to confirm the phone was attached.
This doesn't work for all phones, just the ones listed here: http://developer.android.com/sdk/win-usb.html
HttpClient is deprecated in sdk 23.
You have to move on URLConnection or down sdk to 22
Still you need HttpClient with update gradle sdk 23
You have to add the dependencies of HttpClient in app/gradle as
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
...
}
The simplest solution is :
listView.setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL);
listView.setStackFromBottom(true);
Facebook publishes the SDK on maven central :
Just add :
repositories {
jcenter() // IntelliJ main repo.
}
dependencies {
compile 'com.facebook.android:facebook-android-sdk:+'
}
NOTE: Before trying this code, please find this line in the below code:
private static String DB_NAME ="YourDbName"; // Database name
DB_NAME here is the name of your database. It is assumed that you have a copy of the database in the assets folder, so for example, if your database name is ordersDB, then the value of DB_NAME will be ordersDB,
private static String DB_NAME ="ordersDB";
Keep the database in assets folder and then follow the below:
DataHelper class:
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import android.content.Context;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;
public class DataBaseHelper extends SQLiteOpenHelper {
private static String TAG = "DataBaseHelper"; // Tag just for the LogCat window
private static String DB_NAME ="YourDbName"; // Database name
private static int DB_VERSION = 1; // Database version
private final File DB_FILE;
private SQLiteDatabase mDataBase;
private final Context mContext;
public DataBaseHelper(Context context) {
super(context, DB_NAME, null, DB_VERSION);
DB_FILE = context.getDatabasePath(DB_NAME);
this.mContext = context;
}
public void createDataBase() throws IOException {
// If the database does not exist, copy it from the assets.
boolean mDataBaseExist = checkDataBase();
if(!mDataBaseExist) {
this.getReadableDatabase();
this.close();
try {
// Copy the database from assests
copyDataBase();
Log.e(TAG, "createDatabase database created");
} catch (IOException mIOException) {
throw new Error("ErrorCopyingDataBase");
}
}
}
// Check that the database file exists in databases folder
private boolean checkDataBase() {
return DB_FILE.exists();
}
// Copy the database from assets
private void copyDataBase() throws IOException {
InputStream mInput = mContext.getAssets().open(DB_NAME);
OutputStream mOutput = new FileOutputStream(DB_FILE);
byte[] mBuffer = new byte[1024];
int mLength;
while ((mLength = mInput.read(mBuffer)) > 0) {
mOutput.write(mBuffer, 0, mLength);
}
mOutput.flush();
mOutput.close();
mInput.close();
}
// Open the database, so we can query it
public boolean openDataBase() throws SQLException {
// Log.v("DB_PATH", DB_FILE.getAbsolutePath());
mDataBase = SQLiteDatabase.openDatabase(DB_FILE, null, SQLiteDatabase.CREATE_IF_NECESSARY);
// mDataBase = SQLiteDatabase.openDatabase(DB_FILE, null, SQLiteDatabase.NO_LOCALIZED_COLLATORS);
return mDataBase != null;
}
@Override
public synchronized void close() {
if(mDataBase != null) {
mDataBase.close();
}
super.close();
}
}
Write a DataAdapter class like:
import java.io.IOException;
import android.content.Context;
import android.database.Cursor;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.util.Log;
public class TestAdapter {
protected static final String TAG = "DataAdapter";
private final Context mContext;
private SQLiteDatabase mDb;
private DataBaseHelper mDbHelper;
public TestAdapter(Context context) {
this.mContext = context;
mDbHelper = new DataBaseHelper(mContext);
}
public TestAdapter createDatabase() throws SQLException {
try {
mDbHelper.createDataBase();
} catch (IOException mIOException) {
Log.e(TAG, mIOException.toString() + " UnableToCreateDatabase");
throw new Error("UnableToCreateDatabase");
}
return this;
}
public TestAdapter open() throws SQLException {
try {
mDbHelper.openDataBase();
mDbHelper.close();
mDb = mDbHelper.getReadableDatabase();
} catch (SQLException mSQLException) {
Log.e(TAG, "open >>"+ mSQLException.toString());
throw mSQLException;
}
return this;
}
public void close() {
mDbHelper.close();
}
public Cursor getTestData() {
try {
String sql ="SELECT * FROM myTable";
Cursor mCur = mDb.rawQuery(sql, null);
if (mCur != null) {
mCur.moveToNext();
}
return mCur;
} catch (SQLException mSQLException) {
Log.e(TAG, "getTestData >>"+ mSQLException.toString());
throw mSQLException;
}
}
}
Now you can use it like:
TestAdapter mDbHelper = new TestAdapter(urContext);
mDbHelper.createDatabase();
mDbHelper.open();
Cursor testdata = mDbHelper.getTestData();
mDbHelper.close();
EDIT: Thanks to JDx
For Android 4.1 (Jelly Bean), change:
DB_PATH = "/data/data/" + context.getPackageName() + "/databases/";
to:
DB_PATH = context.getApplicationInfo().dataDir + "/databases/";
in the DataHelper class, this code will work on Jelly Bean 4.2 multi-users.
EDIT: Instead of using hardcoded path, we can use
DB_PATH = context.getDatabasePath(DB_NAME).getAbsolutePath();
which will give us the full path to the database file and works on all Android versions
You can scale bitmaps by using canvas.drawBitmap with providing matrix, for example:
public static Bitmap scaleBitmap(Bitmap bitmap, int wantedWidth, int wantedHeight) {
Bitmap output = Bitmap.createBitmap(wantedWidth, wantedHeight, Config.ARGB_8888);
Canvas canvas = new Canvas(output);
Matrix m = new Matrix();
m.setScale((float) wantedWidth / bitmap.getWidth(), (float) wantedHeight / bitmap.getHeight());
canvas.drawBitmap(bitmap, m, new Paint());
return output;
}
The best way to run shell on any particular device is to use:
adb -s << emulator UDID >> shell
For Example:
adb -s emulator-5554 shell
ImageView imageView=findViewById(R.id.imageView)
if you have image in drawable folder then use
imageView.setImageResource(R.drawable.imageView)
if you have uri and want to display it in imageView then use
imageView.setImageUri("uri")
if you have bitmap and want to display it in imageView then use
imageView.setImageBitmap(bitmap)
note:- 1. imageView.setImageDrawable()
is now deprecated in java
2. If image uri is from firebase or from any other online link then use
Picasso.get()
.load("uri")
.into(imageView)
(https://github.com/square/picasso)
or use
Glide.with(context)
.load("uri")
.into(imageView)
Below is the code that works with both the email or messaging app. If you share through email then the subject and body both are added.
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
String shareString = Html.fromHtml("Medicine Name:" + medicine_name +
"<p>Store Name:" + “store_name “+ "</p>" +
"<p>Store Address:" + “store_address” + "</p>") .toString();
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Medicine Enquiry");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareString);
if (sharingIntent.resolveActivity(context.getPackageManager()) != null)
context.startActivity(Intent.createChooser(sharingIntent, "Share using"));
else {
Toast.makeText(context, "No app found on your phone which can perform this action", Toast.LENGTH_SHORT).show();
}
Imagine that we have 3 buttons for example
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Capture our button from layout
Button button = (Button)findViewById(R.id.corky);
Button button2 = (Button)findViewById(R.id.corky2);
Button button3 = (Button)findViewById(R.id.corky3);
// Register the onClick listener with the implementation above
button.setOnClickListener(mCorkyListener);
button2.setOnClickListener(mCorkyListener);
button3.setOnClickListener(mCorkyListener);
}
// Create an anonymous implementation of OnClickListener
private View.OnClickListener mCorkyListener = new View.OnClickListener() {
public void onClick(View v) {
// do something when the button is clicked
// Yes we will handle click here but which button clicked??? We don't know
}
};
}
So what we will do?
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Capture our button from layout
Button button = (Button)findViewById(R.id.corky);
Button button2 = (Button)findViewById(R.id.corky2);
Button button3 = (Button)findViewById(R.id.corky3);
// Register the onClick listener with the implementation above
button.setOnClickListener(mCorkyListener);
button2.setOnClickListener(mCorkyListener);
button3.setOnClickListener(mCorkyListener);
}
// Create an anonymous implementation of OnClickListener
private View.OnClickListener mCorkyListener = new View.OnClickListener() {
public void onClick(View v) {
// do something when the button is clicked
// Yes we will handle click here but which button clicked??? We don't know
// So we will make
switch (v.getId() /*to get clicked view id**/) {
case R.id.corky:
// do something when the corky is clicked
break;
case R.id.corky2:
// do something when the corky2 is clicked
break;
case R.id.corky3:
// do something when the corky3 is clicked
break;
default:
break;
}
}
};
}
Or we can do this:
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Capture our button from layout
Button button = (Button)findViewById(R.id.corky);
Button button2 = (Button)findViewById(R.id.corky2);
Button button3 = (Button)findViewById(R.id.corky3);
// Register the onClick listener with the implementation above
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// do something when the corky is clicked
}
});
button2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// do something when the corky2 is clicked
}
});
button3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// do something when the corky3 is clicked
}
});
}
}
Or we can implement View.OnClickListener and i think it's the best way:
public class MainActivity extends ActionBarActivity implements View.OnClickListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Capture our button from layout
Button button = (Button)findViewById(R.id.corky);
Button button2 = (Button)findViewById(R.id.corky2);
Button button3 = (Button)findViewById(R.id.corky3);
// Register the onClick listener with the implementation above
button.setOnClickListener(this);
button2.setOnClickListener(this);
button3.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// do something when the button is clicked
// Yes we will handle click here but which button clicked??? We don't know
// So we will make
switch (v.getId() /*to get clicked view id**/) {
case R.id.corky:
// do something when the corky is clicked
break;
case R.id.corky2:
// do something when the corky2 is clicked
break;
case R.id.corky3:
// do something when the corky3 is clicked
break;
default:
break;
}
}
}
Finally there is no real differences here Just "Way better than the other"
If you are using Toolbar, you don't need those solutions. You only have to change the theme of the toolbar
app:theme="@style/ThemeOverlay.AppCompat.Light"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
If you are using a dark.actionBar your back button is going to be white else if you are using light actionbar theme it is going to be black.
File sdCard = Environment.getExternalStorageDirectory();
File dir = new File (sdCard.getAbsolutePath() + "/dir1/dir2");
dir.mkdirs();
File file = new File(dir, "filename");
FileOutputStream f = new FileOutputStream(file);

If you want to set cursor position in EditText? try these below code
EditText rename;
String title = "title_goes_here";
int counts = (int) title.length();
rename.setSelection(counts);
rename.setText(title);
How I update my deviceToken
First when I login I send the first device token under the user collection and the current logged in user.
After that, I just override onNewToken(token:String)
in my FirebaseMessagingService()
and just update that value if a new token is generated for that user
class MyFirebaseMessagingService: FirebaseMessagingService() {
override fun onMessageReceived(p0: RemoteMessage) {
super.onMessageReceived(p0)
}
override fun onNewToken(token: String) {
super.onNewToken(token)
val currentUser= FirebaseAuth.getInstance().currentUser?.uid
if(currentUser != null){
FirebaseFirestore.getInstance().collection("user").document(currentUser).update("deviceToken",token)
}
}
}
Each time your app opens it will check for a new token, if the user is not yet signed in it will not update the token, if the user is already logged in you can check for a newToken
Also as a minor enhancement.
The main reason for the try/catch block is that e1 could be null for the initial movement. in addition to the try/catch, include a test for null and return. similar to the following
if (e1 == null || e2 == null) return false;
try {
...
} catch (Exception e) {}
return false;
This method worked for me:
RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.layout.rootLayout);
relativeLayout.setBackgroundColor(getResources().getColor(R.color.bg_color_2));
Set id in layout xml
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/rootLayout"
android:background="@color/background_color"
Add color values/color.xml
<color name="bg_color_2">#ffeef7f0</color>
For some who still got this issue to solve even after applying the suggestion of this thread(i used to be one like that) add this line on your Application class, onCreate() method
AppCompatDelegate.setCompatVectorFromResourcesEnabled(true)
As suggested here and here sometimes this is required to access vectors from resources especially when you're dealing with menu items, etc
The OOM exception could be avoided by following the official guide to load large bitmap.
Don't run your code on the UI Thread. Use AsyncTask instead and you should be fine.
add Internet permission in manifest
<uses-permission android:name="android.permission.INTERNET" />
than create methode as below,
public static Bitmap getBitmapFromURL(String src) {
try {
Log.e("src", src);
URL url = new URL(src);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
Bitmap myBitmap = BitmapFactory.decodeStream(input);
Log.e("Bitmap", "returned");
return myBitmap;
} catch (IOException e) {
e.printStackTrace();
Log.e("Exception", e.getMessage());
return null;
}
}
now add this in your onCreate method,
ImageView img_add = (ImageView) findViewById(R.id.img_add);
img_add.setImageBitmap(getBitmapFromURL("http://www.deepanelango.me/wpcontent/uploads/2017/06/noyyal1.jpg"));
this is works for me.
I solved that issue follow that:
Steps:
When it replies to the ping, connect it via USB, and:
adb usb
adb tcpip 5555
adb connect 194.68.0.100:5555
In casr it's still not connected, try to switch the usb connection mode as MTP / PTP / Camera while the device is connected through usb and repeat these steps over again...
If you only have one typeface you would like to add, and want less code to write, you can create a dedicated TextView for your specific font. See code below.
package com.yourpackage;
import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;
public class FontTextView extends TextView {
public static Typeface FONT_NAME;
public FontTextView(Context context) {
super(context);
if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/FontName.otf");
this.setTypeface(FONT_NAME);
}
public FontTextView(Context context, AttributeSet attrs) {
super(context, attrs);
if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/FontName.otf");
this.setTypeface(FONT_NAME);
}
public FontTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/FontName.otf");
this.setTypeface(FONT_NAME);
}
}
In main.xml, you can now add your textView like this:
<com.yourpackage.FontTextView
android:id="@+id/tvTimer"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="" />
If you use the gson.JsonObject you can have something like that:
import com.google.gson.JsonObject;
import com.google.gson.JsonParser;
String jsonString = "{'test1':'value1','test2':{'id':0,'name':'testName'}}"
JsonObject jsonObject = (JsonObject) jsonParser.parse(jsonString)
I was having the same problem and could not figure out what I was doing wrong. Turns out, the auto-complete for Android Studio was changing the text to either all caps or all lower case (depending on whether I typed in upper case or lower cast words before the auto-complete). The OS was not registering the name due to this issue and I would get the error regarding a missing permission. As stated above, ensure your permissions are labeled correctly:
Correct:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Incorrect:
<uses-permission android:name="ANDROID.PERMISSION.ACCESS_FINE_LOCATION" />
Incorrect:
<uses-permission android:name="android.permission.access_fine_location" />
Though this may seem trivial, its easy to overlook.
If there is some setting to make permissions non-case-sensitive, please add a comment with the instructions. Thank you!
Excellent answer from above turned into a simple utility method.
private Uri buildURI(String url, Map<String, String> params) {
// build url with parameters.
Uri.Builder builder = Uri.parse(url).buildUpon();
for (Map.Entry<String, String> entry : params.entrySet()) {
builder.appendQueryParameter(entry.getKey(), entry.getValue());
}
return builder.build();
}
Edit 2: What I've written below will not actually work. Google has rejected an app that includes a call to ActivityManager.getRunningTasks(). From the documentation, it is apparent that this API is for debugging and development purposes only. I'll be updating this post as soon as I have time to update the GitHub project below with a new scheme that uses timers and is almost as good.
Edit 1: I've written up a blog post and created a simple GitHub repository to make this really easy.
The accepted and top rated answer are both not really the best approach. The top rated answer's implementation of isApplicationBroughtToBackground() does not handle the situation where the Application's main Activity is yielding to an Activity that is defined in the same Application, but it has a different Java package. I came up with a way to do this that will work in that case.
Call this in onPause(), and it will tell you if your application is going into the background because another application has started, or the user has pressed the home button.
public static boolean isApplicationBroughtToBackground(final Activity activity) {
ActivityManager activityManager = (ActivityManager) activity.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningTaskInfo> tasks = activityManager.getRunningTasks(1);
// Check the top Activity against the list of Activities contained in the Application's package.
if (!tasks.isEmpty()) {
ComponentName topActivity = tasks.get(0).topActivity;
try {
PackageInfo pi = activity.getPackageManager().getPackageInfo(activity.getPackageName(), PackageManager.GET_ACTIVITIES);
for (ActivityInfo activityInfo : pi.activities) {
if(topActivity.getClassName().equals(activityInfo.name)) {
return false;
}
}
} catch( PackageManager.NameNotFoundException e) {
return false; // Never happens.
}
}
return true;
}
For Track the location every 10 mins(based on requirement) please follow this link it is working fine without any issues
https://github.com/safetysystemtechnology/location-tracker-background
you can directly give the Image name in your setimage as iv.setImageResource(R.drawable.apple);
that should be it.
Another way of doing it is defining a resources array in strings.xml like below.
<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE resources [
<!ENTITY supportDefaultSelection "Choose your issue">
<!ENTITY issueOption1 "Support">
<!ENTITY issueOption2 "Feedback">
<!ENTITY issueOption3 "Help">
]>
and then defining a string array using the above resources
<string-array name="support_issues_array">
<item>&supportDefaultSelection;</item>
<item>&issueOption1;</item>
<item>&issueOption2;</item>
<item>&issueOption3;</item>
</string-array>
You could refer the same string into other xmls too keeping DRY intact. The advantage I see is, with a single value change it would effect all the references in the code.
Try this:
int dayOfWeek = date.get(Calendar.DAY_OF_WEEK);
String weekday = new DateFormatSymbols().getShortWeekdays()[dayOfWeek];
If you want programmatic setText without add string to string.xml
see its hexadecimal code here:
http://fortawesome.github.io/Font-Awesome/cheatsheet/
replace  to 0xf066
Typeface typeface = Typeface.createFromAsset(getAssets(), "fontawesome-webfont.ttf");
textView.setTypeface(typeface);
textView.setText(new String(new char[]{0xf006 }));
<ImageView
android:id="@+id/iv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:src="@drawable/temp"
/>
you can try to this , then you get a bitmap of selected image and then you can easily find it's native path from Device Default Gallery.
Bitmap roughBitmap= null;
try {
// Works with content://, file://, or android.resource:// URIs
InputStream inputStream =
getContentResolver().openInputStream(uri);
roughBitmap= BitmapFactory.decodeStream(inputStream);
// calc exact destination size
Matrix m = new Matrix();
RectF inRect = new RectF(0, 0, roughBitmap.Width, roughBitmap.Height);
RectF outRect = new RectF(0, 0, dstWidth, dstHeight);
m.SetRectToRect(inRect, outRect, Matrix.ScaleToFit.Center);
float[] values = new float[9];
m.GetValues(values);
// resize bitmap if needed
Bitmap resizedBitmap = Bitmap.CreateScaledBitmap(roughBitmap, (int) (roughBitmap.Width * values[0]), (int) (roughBitmap.Height * values[4]), true);
string name = "IMG_" + new Java.Text.SimpleDateFormat("yyyyMMdd_HHmmss").Format(new Java.Util.Date()) + ".png";
var sdCardPath= Environment.GetExternalStoragePublicDirectory("DCIM").AbsolutePath;
Java.IO.File file = new Java.IO.File(sdCardPath);
if (!file.Exists())
{
file.Mkdir();
}
var filePath = System.IO.Path.Combine(sdCardPath, name);
} catch (FileNotFoundException e) {
// Inform the user that things have gone horribly wrong
}
In Android Studio 3.0 and later do this:
View > Tool Windows > Device File Explorer
AArch64 is the 64-bit state introduced in the Armv8-A architecture (https://en.wikipedia.org/wiki/ARM_architecture#ARMv8-A). The 32-bit state which is backwards compatible with Armv7-A and previous 32-bit Arm architectures is referred to as AArch32. Therefore the GNU triplet for the 64-bit ISA is aarch64. The Linux kernel community chose to call their port of the kernel to this architecture arm64 rather than aarch64, so that's where some of the arm64 usage comes from.
As far as I know the Apple backend for aarch64 was called arm64 whereas the LLVM community-developed backend was called aarch64 (as it is the canonical name for the 64-bit ISA) and later the two were merged and the backend now is called aarch64.
So AArch64 and ARM64 refer to the same thing.
android:gravity
handles the alignment of its children,
android:layout_gravity
handles the alignment of itself.
So use one of these.

If your device supports multiple users, you might have to delete the app for each account as well.
I usually use adb and that does the trick
adb uninstall <your-package-name>
If you converted Bitmap into Base64 in projects and save it to parcelable object you shuold resize bitmap with below code ,
replace png with jpeg and replace quality 100 to 75 or 60 :
bitmap.compress(Bitmap.CompressFormat.JPEG, 75, byteArrayOutputStream)
this solution works for me

On Mac, the Android SDK gets installed at: /Users/username/Library/Android/sdk/
, therefore, you will need to run the script as sudo, as follows:
sudo sh /Users/username/Library/Android/sdk/extras/intel/Hardware_Accelerated_Execution_Manager/silent_install.sh
If all goes well, the script prints the message: "Silent installation Pass!"
Then, restart Android Studio and run your app with the desired AVD.
try like this. hope it works

xxxhdpi was only introduced because of the way that launcher icons are scaled on the nexus 5's launcher Because the nexus 5's default launcher uses bigger icons, xxxhdpi was introduced so that icons would still look good on the nexus 5's launcher.

A very simple approach for the dev who just want to send POST parameters in multipart request.
Make the following changes in class which extends Request.java
First define these constants :
String BOUNDARY = "s2retfgsGSRFsERFGHfgdfgw734yhFHW567TYHSrf4yarg"; //This the boundary which is used by the server to split the post parameters.
String MULTIPART_FORMDATA = "multipart/form-data;boundary=" + BOUNDARY;
Add a helper function to create a post body for you :
private String createPostBody(Map<String, String> params) {
StringBuilder sbPost = new StringBuilder();
if (params != null) {
for (String key : params.keySet()) {
if (params.get(key) != null) {
sbPost.append("\r\n" + "--" + BOUNDARY + "\r\n");
sbPost.append("Content-Disposition: form-data; name=\"" + key + "\"" + "\r\n\r\n");
sbPost.append(params.get(key).toString());
}
}
}
return sbPost.toString();
}
Override getBody() and getBodyContentType
public String getBodyContentType() {
return MULTIPART_FORMDATA;
}
public byte[] getBody() throws AuthFailureError {
return createPostBody(getParams()).getBytes();
}
I have been implementing installation without user consent recently - it was a kiosk application for API level 21+ where I had full control over environment.
The basic requirements are
The following method reads and installs APK from InputStream:
public static boolean installPackage(Context context, InputStream in, String packageName)
throws IOException {
PackageInstaller packageInstaller = context.getPackageManager().getPackageInstaller();
PackageInstaller.SessionParams params = new PackageInstaller.SessionParams(
PackageInstaller.SessionParams.MODE_FULL_INSTALL);
params.setAppPackageName(packageName);
// set params
int sessionId = packageInstaller.createSession(params);
PackageInstaller.Session session = packageInstaller.openSession(sessionId);
OutputStream out = session.openWrite("COSU", 0, -1);
byte[] buffer = new byte[65536];
int c;
while ((c = in.read(buffer)) != -1) {
out.write(buffer, 0, c);
}
session.fsync(out);
in.close();
out.close();
Intent intent = new Intent(context, MainActivity.class);
intent.putExtra("info", "somedata"); // for extra data if needed..
Random generator = new Random();
PendingIntent i = PendingIntent.getActivity(context, generator.nextInt(), intent,PendingIntent.FLAG_UPDATE_CURRENT);
session.commit(i.getIntentSender());
return true;
}
The following code calls the installation
try {
InputStream is = getResources().openRawResource(R.raw.someapk_source);
installPackage(MainActivity.this, is, "com.example.apk");
} catch (IOException e) {
Toast.makeText(MainActivity.this, e.getMessage(), Toast.LENGTH_SHORT).show();
}
for the whole thing to work you desperately need INSTALL_PACKAGES
permission, or the code above will fail silently
<uses-permission
android:name="android.permission.INSTALL_PACKAGES" />
to get this permission you must install your APK as System application which REQUIRES root (however AFTER you have installed your updater application it seem to work WITHOUT root)
To install as system application I created a signed APK and pushed it with
adb push updater.apk /sdcard/updater.apk
and then moved it to system/priv-app
- which requires remounting FS (this is why the root is required)
adb shell
su
mount -o rw,remount /system
mv /sdcard/updater.apk /system/priv-app
chmod 644 /system/priv-app/updater.apk
for some reason it didn't work with simple debug version, but logcat shows useful info if your application in priv-app
is not picked up for some reason.
<activity android:name="com.example.abc"
android:configChanges="orientation|screenSize"></activity>
Just add android:configChanges="orientation|screenSize"
in activity tab of manifest file.
So, Activity won't restart when orientation change.
public class Main extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
EditText et = (EditText) findViewById(R.id.et);
EditText et_city = (EditText) findViewById(R.id.et_city);
// Set the default text of second EditText widget
et_city.setText("USA");
}
}
A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.
This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.
Whereas a GridLayout is a layout that places its children in a rectangular grid.
It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.
You have to define your TASK_CAT
column first and then set foreign key on it.
private static final String TASK_TABLE_CREATE = "create table "
+ TASK_TABLE + " ("
+ TASK_ID + " integer primary key autoincrement, "
+ TASK_TITLE + " text not null, "
+ TASK_NOTES + " text not null, "
+ TASK_DATE_TIME + " text not null,"
+ TASK_CAT + " integer,"
+ " FOREIGN KEY ("+TASK_CAT+") REFERENCES "+CAT_TABLE+"("+CAT_ID+"));";
More information you can find on sqlite foreign keys doc.
This was my solution. Hope my confusion can help someone else too:
My "Developer Options" was ON,
but the "USB Debbugging" was OFF.
So I turned ON the USB Debbugging and the problem was solved.
The app can't be run natively, but it could be run on an emulator. You can use ManyMo to embed them in a website and make users add your app to their home screen. This link should be useful for making the app more realistic. Users could then only press the share button and add the app to their home screen. All data will be deleted when the "app" is closed in their iOS devices so you should use the Internet/cloud for storage. It can't access camera or multi touch, but it may be useful.
public View getView(final int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = getLayoutInflater();
View row = inflater.inflate(R.layout.vehicals_details_row, parent, false);
Button deleteImageView = (Button) row.findViewById(R.id.DeleteImageView);
deleteImageView.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//...
}
});
}
But you can get an issue - listView row not clickable. Solution:
android:focusable="true"
android:focusable="false"
Updated Answer
As of June11, 2018 it is now mandatory to have a billing account to get API key. You can still make keyless calls to the Maps JavaScript API and Street View Static API which will return low-resolution maps that can be used for development. Enabling billing still gives you $200 free credit monthly for your projects.
This answer is no longer valid
As long as you're using a testing API key it is free to register and use. But when you move your app to commercial level you have to pay for it. When you enable billing, google gives you $200 credit free each month that means if your app's map usage is low you can still use it for free even after the billing enabled, if it exceeds the credit limit now you have to pay for it.
To add to Alex Kucherenko solution: the issue with the cursor getting disappearing after calling setInputType(0)
is due to a framework bug on ICS (and JB).
The bug is documented here: https://code.google.com/p/android/issues/detail?id=27609.
To workaround this, call setRawInputType(InputType.TYPE_CLASS_TEXT)
right after the setInputType
call.
To stop the keyboard from appearing, just override OnTouchListener
of the EditText and return true (swallowing the touch event):
ed.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
return true;
}
});
The reasons for the cursor appearing on GB devices and not on ICS+ had me tearing my hair out for a couple of hours, so I hope this saves someone's time.
I navigate to:
/usr/lib/android-sdk/licenses
and I typed in terminal:
echo -e "\n8933bad161af4178b1185d1a37fbf41ea5269c55" > $ANDROID_SDK/licenses/android-sdk-license"
With root permission. And it works for me now.
File-> Settings->Under IDE Settings click on Plugins. Now in right side window Click on Browse repositories and there you can find the plugins. Select which one you want and click on install
This always can happen in DataBinding. Try to stay away from adding logic in your bindings, including appending an empty string. You can make your own custom adapter, and use it multiple times.
@BindingAdapter("numericText")
fun numericText(textView: TextView, value: Number?) {
value?.let {
textView.text = value.toString()
}
}
<TextView app:numericText="@{list.size()}" .../>
Add this 2 lines in your code -
mWebView.setWebChromeClient(new WebChromeClient());
mWebView.setWebViewClient(new WebViewClient());?
extension Date {
func isBetween(_ date1: Date, and date2: Date) -> Bool {
return (min(date1, date2) ... max(date1, date2)).contains(self)
}
}
let resultArray = dateArray.filter { $0.dateObj!.isBetween(startDate, and: endDate) }
This is what a constant expression in Java looks like:
package com.mycompany.mypackage;
public class MyLinks {
// constant expression
public static final String GUESTBOOK_URL = "/guestbook";
}
You can use it with annotations as following:
import com.mycompany.mypackage.MyLinks;
@WebServlet(urlPatterns = {MyLinks.GUESTBOOK_URL})
public class GuestbookServlet extends HttpServlet {
// ...
}
final means you can't change the value of that variable once it was assigned.
Meanwhile, the use of final for the arguments in those methods means it won't allow the programmer to change their value during the execution of the method. This only means that inside the method the final variables can not be reassigned.

There are already nice solution has been given. The below code can help others to query over datatable and get the value of each row of the datatable for the ImagePath column.
for (int i = 0; i < dataTable.Rows.Count; i++)
{
var theUrl = dataTable.Rows[i]["ImagePath"].ToString();
}
The following seemed to work well for me:

If you're using Python 3
then you must install as follows:
sudo apt-get update
sudo apt-get install python3-tk
Tkinter for Python 2
(python-tk
) is different from Python 3
's (python3-tk
).
How about using Pandas to read the csv file into a DataFrame (pd.read_csv), then manipulating the columns if you want (dropping them or updating values) and finally converting the DataFrame back to JSON (pd.DataFrame.to_json).
Note: I haven't checked how efficient this will be but this is definitely one of the easiest ways to manipulate and convert a large csv to json.
You are not specifying a language or framework, but the following header is used for file downloads:
"Content-Disposition: attachment; filename=abc.csv"
Essentially, and as-noted by @kevin-b:
// find('#id')
angular.element(document.querySelector('#id'))
//find('.classname'), assumes you already have the starting elem to search from
angular.element(elem.querySelector('.classname'))
Note: If you're looking to do this from your controllers you may want to have a look at the "Using Controllers Correctly" section in the developers guide and refactor your presentation logic into appropriate directives (such as <a2b ...>).
As you didn't give us very much information, I'm assuming the language you're writing the code in is C#. First of all: Prefer System.Collections.Generic.List over an ArrayList. Secondly: One way would be to loop through every item in the list and check whether it contains "How". Another way would be to use LINQ. Here's a quick example that filters out every item which doesn't contain "How":
var list = new List<string>();
list.AddRange(new string[] {
"How are you?",
"How you doing?",
"Joe",
"Mike", });
foreach (string str in list.Where(s => s.Contains("How")))
{
Console.WriteLine(str);
}
Console.ReadLine();
There is nothing you can do on your end (client side). You can not enable crossDomain calls yourself, the source (dailymotion.com) needs to have CORS enabled for this to work.
The only thing you can really do is to create a server side proxy script which does this for you. Are you using any server side scripts in your project? PHP, Python, ASP.NET etc? If so, you could create a server side "proxy" script which makes the HTTP call to dailymotion and returns the response. Then you call that script from your Javascript code, since that server side script is on the same domain as your script code, CORS will not be a problem.
A tab is a tab. How many spaces it consumes is a display issue, and depends on the settings of your shell.
If you want to control the width of your data, then you could use the width
sub-specifiers in the printf
format string. Eg. :
printf("%5d", 2);
It's not a complete solution (if the value is longer than 5 characters, it will not be truncated), but might be ok for your needs.
If you want complete control, you'll probably have to implement it yourself.
You can access the raw DOM element with:
$("table").get(0);
or more simply:
$("table")[0];
There isn't actually a lot you need this for however (in my experience). Take your checkbox example:
$(":checkbox").click(function() {
if ($(this).is(":checked")) {
// do stuff
}
});
is more "jquery'ish" and (imho) more concise. What if you wanted to number them?
$(":checkbox").each(function(i, elem) {
$(elem).data("index", i);
});
$(":checkbox").click(function() {
if ($(this).is(":checked") && $(this).data("index") == 0) {
// do stuff
}
});
Some of these features also help mask differences in browsers too. Some attributes can be different. The classic example is AJAX calls. To do this properly in raw Javascript has about 7 fallback cases for XmlHttpRequest
.
To produce patch for several commits, you should use format-patch
git command, e.g.
git format-patch -k --stdout R1..R2
This will export your commits into patch file in mailbox format.
To generate patch for the last commit, run:
git format-patch -k --stdout HEAD^
Then in another repository apply the patch by am
git command, e.g.
git am -3 -k file.patch
See: man git-format-patch
and git-am
.
I thought it would be helpful to consolidate the latest information on scroll bars, CSS, and browser compatibility.
Currently, there exists no cross-browser scroll bar CSS styling definitions. The W3C article I mention at the end has the following statement and was recently updated (10 Oct 2014):
Some browsers (IE, Konqueror) support the non-standard properties 'scrollbar-shadow-color', 'scrollbar-track-color' and others. These properties are illegal: they are neither defined in any CSS specification nor are they marked as proprietary (by prefixing them with "-vendor-")
As others have mentioned, Microsoft supports scroll bar styling, but only for IE8 and above.
Example:
<!-- language: lang-css -->
.TA {
scrollbar-3dlight-color:gold;
scrollbar-arrow-color:blue;
scrollbar-base-color:;
scrollbar-darkshadow-color:blue;
scrollbar-face-color:;
scrollbar-highlight-color:;
scrollbar-shadow-color:
}
Similarly, WebKit now has its own version:
From Custom scrollbars in WebKit, relevant CSS:
/* pseudo elements */
::-webkit-scrollbar { }
::-webkit-scrollbar-button { }
::-webkit-scrollbar-track { }
::-webkit-scrollbar-track-piece { }
::-webkit-scrollbar-thumb { }
::-webkit-scrollbar-corner { }
::-webkit-resizer { }
/* pseudo class selectors */
:horizontal
:vertical
:decrement
:increment
:start
:end
:double-button
:single-button
:no-button
:corner-present
:window-inactive
As of version 64 Firefox supports scrollbar styling through the properties scrollbar-color
(partially, W3C draft) and scrollbar-width
(W3C draft). Some good information about the implementation can be found in this answer.
JavaScript libraries and plug-ins can provide a cross-browser solution. There are many options.
The list could go on. Your best bet is to search around, research, and test the available solutions. I am sure you will be able to find something that will fit your needs.
Just in case you want to prevent scroll bar styling that hasn't been properly prefixed with "-vendor", this article over at W3C provides some basic instructions. Basically, you'll need to add the following CSS to a user style sheet associated with your browser. These definitions will override invalid scroll bar styling on any page you visit.
body, html {
scrollbar-face-color: ThreeDFace !important;
scrollbar-shadow-color: ThreeDDarkShadow !important;
scrollbar-highlight-color: ThreeDHighlight !important;
scrollbar-3dlight-color: ThreeDLightShadow !important;
scrollbar-darkshadow-color: ThreeDDarkShadow !important;
scrollbar-track-color: Scrollbar !important;
scrollbar-arrow-color: ButtonText !important;
}

In IIS, you can specify a redirect to "certain" page based on error code. In you example, you can configure 404 - > Your customized 404 error page.
The fact that you're using a view model has no bearing. The standard way of using PagedList
is to store "one page of items" as a ViewBag
variable. All you have to determine is what collection constitutes what you'll be paging over. You can't logically page multiple collections at the same time, so assuming you chose Instructors
:
ViewBag.OnePageOfItems = myViewModelInstance.Instructors.ToPagedList(pageNumber, 10);
Then, the rest of the standard code works as it always has.
SomeVal=ActiveWorkbook.worksheets("Sheet2").cells(aRow,aCol).Value
did not work. However the following code only worked for me.
SomeVal = ThisWorkbook.Sheets(2).cells(aRow,aCol).Value
The IF statement has these forms in PL/SQL
:
IF THEN
IF THEN ELSE
IF THEN ELSIF
You have used elseif
which in terms of PL/SQL is wrong. That need to be replaced with ELSIF
.
So your code should appear like this.
declare
var_number number;
begin
var_number := 10;
if var_number > 100 then
dbms_output.put_line(var_number ||' is greater than 100');
--elseif should be replaced with elsif
elsif var_number < 100 then
dbms_output.put_line(var_number ||' is less than 100');
else
dbms_output.put_line(var_number ||' is equal to 100');
end if;
end;
The simplest way is to set the vertical-align css property to middle
i.fa {
vertical-align: middle;
}
$@
is the name of the target being generated, and $<
the first prerequisite (usually a source file). You can find a list of all these special variables in the GNU Make manual.
For example, consider the following declaration:
all: library.cpp main.cpp
In this case:
$@
evaluates to all
$<
evaluates to library.cpp
$^
evaluates to library.cpp main.cpp
In "Package Explorer" view, Right click your test class, then "Build Path">>"Include", it should be OK.
Like this:

For those who want an actual URL object, potentially for a utility which takes URLs as an argument:
const url = new URL(window.location.href)
Chr(10)
is the Line Feed character and Chr(13)
is the Carriage Return character.
You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.
Historically, Line Feed would move down a line but not return to column 1:
This
is
a
test.
Similarly Carriage Return would return to column 1 but not move down a line:
This
is
a
test.
Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.
Actually, you can always test it by yourself.
CREATE TABLE CUSTOMERS
(
CUSTOMER_ID NUMBER NOT NULL,

)
;
select column_name, data_type, nullable, data_length, data_precision, data_scale from user_tab_columns where table_name ='CUSTOMERS';
Like @Shoaib answered, you dont need any jQuery or Javascript. You can to this simply with pure html!
<form method="POST" action="index.php?action=contact_agent">
<select name="agent_id" required>
<option value="1">Agent Homer</option>
<option value="2">Agent Lenny</option>
<option value="3">Agent Carl</option>
</select>
<input type="submit" value="Submit">
</form>
&agent_id=
from form action since you don't need it there.name="agent_id"
to the selectrequired
do indicate that this selection is required.Since you are using PHP, then by posting the form to index.php
you can catch agent_id
with $_POST
/** Since you reference action on `form action` then value of $_GET['action'] will be contact_agent */
$action = $_GET['action'];
/** Value of $_POST['agent_id'] will be selected option value */
$agent_id = $_POST['agent_id'];
As conclusion for such a simple task you should not use any javascript or jQuery. To @FelipeAlvarez that answers your comment
For those times when you need to use jquery to set !important properties, here is a plugin I build that will allow you to do so.
$.fn.important = function(key, value) {
var q = Object.assign({}, this.style)
q[key] = `${value} !important`;
$(this).css("cssText", Object.entries(q).filter(x => x[1]).map(([k, v]) => (`${k}: ${v}`)).join(';'));
};
$('div').important('color', 'red');
The basic difference between
Blockquote
asymptotically upper bound and asymptotically tight Asym.upperbound means a given algorythm that can executes with maximum amount of time depending upon the number of inputs ,for eg in sorting algo if all the array (n)elements are in descending order then for ascending them it will take a running time of O(n) which shows upper bound complexity ,but if they are already sorted then it will take ohm(1).so we generally used "O"notation for upper bound complexity.
Asym. tightbound bound shows the for eg(c1g(n)<=f(n)<=c2g(n)) shows the tight bound limit such that the function have the value in between two bound (upper bound and lower bound),giving the average case.
Just as Daniel said "Git and TFVC are the two source control options in TFS
". Fortunately both are supported for now in VS Code.
You need to install the Azure Repos Extension for Visual Studio Code. The process of installing is pretty straight forward.
Add the following lines to your user settings
If you have VS 2015 installed on your machine, your path to Team Foundation tool (tf.exe) may look like this:
{ "tfvc.location": "C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\Common7\\IDE\\tf.exe", "tfvc.restrictWorkspace": true }
Or for VS 2017:
{ "tfvc.location": "C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Enterprise\\Common7\\IDE\\CommonExtensions\\Microsoft\\TeamFoundation\\Team Explorer\\tf.exe", "tfvc.restrictWorkspace": true }
Open a local folder (repository), From View -> Command Pallette ..., type team signin
Provide user name --> Enter --> Provide password to connect to TFS.
Please refer to below links for more details:
Note that Server Workspaces are not supported:
"TFVC support is limited to Local workspaces":
If your Android studio has been updated.
Maybe, you would face an error in the studio like "AAPT 2 error: check the log for details"
This error will occur when you have done something wrong in your .xml file such as incorrect value, content not found, etc.
But, At that time you will not have the error specification there. Because the new version of Android Studio does not give you a specific error. It gives like AAPT2 error.
If you want to know where the actual error is then
- Look at the panel which is at the right of your Android studio Check out the "Gradle" tab and click on it.
- You will see the "app" option. Click on it.
- In the app options you will see [Tasks -> build] click on it.
- Then you will get options list and see "assembleDebug" double click on it.
- Keep the patience and See build tab at the bottom panel of Android studios, you will get an exact error there what you made a mistake in which file and which position.
You can use Arrays.copyOf()
with a little reflection to make a nice helper function.
public class ArrayHelper {
public static <T> T[] push(T[] arr, T item) {
T[] tmp = Arrays.copyOf(arr, arr.length + 1);
tmp[tmp.length - 1] = item;
return tmp;
}
public static <T> T[] pop(T[] arr) {
T[] tmp = Arrays.copyOf(arr, arr.length - 1);
return tmp;
}
}
Usage:
String[] items = new String[]{"a", "b", "c"};
items = ArrayHelper.push(items, "d");
items = ArrayHelper.push(items, "e");
items = ArrayHelper.pop(items);
Results
Original: a,b,c
Array after push calls: a,b,c,d,e
Array after pop call: a,b,c,d
Using Python will be one easy way to achieve what you want.
I found one using Google.
"convert from json to csv using python" is an example.
HTML :
<div id="myDiv">
<form id="myForm">
</form>
</div>
jQuery :
var chbx='<input type="checkbox" id="Mumbai" name="Mumbai" value="Mumbai" />Mumbai<br /> <input type="checkbox" id=" Delhi" name=" Delhi" value=" Delhi" /> Delhi<br/><input type="checkbox" id=" Bangalore" name=" Bangalore" value=" Bangalore"/>Bangalore<br />';
$("#myDiv form#myForm").html(chbx);
//to insert dynamically created form
$("#myDiv").html("<form id='dynamicForm'>" +chbx + "'</form>");
$(document).ready(function() {
//Fix dropdown-menu box size upto 2 items but above 2 items scroll the menu box
$("#dropdown").click(function() {
var maxHeight = 301;
if ($(".dropdown-menu").height() > maxHeight) {
maxHeight = 302;
$(".dropdown-menu").height(maxHeight);
$(".dropdown-menu").css({'overflow-y':'scroll'});
} else {
$(".dropdown-menu").height();
$(".dropdown-menu").css({'overflow-y':'hidden'});
}
});
});

If you encounter this problem and UI Controls were created on a separate worker thread when working with BitmapSource
or ImageSource
in WPF, call Freeze()
method first before passing the BitmapSource
or ImageSource
as a parameter to any method. Using Application.Current.Dispatcher.Invoke()
does not work in such instances
Have you tried using the !important flag on the style? !important allows you to decide which style will win out. Also note !important will override inline styles as well.
#example p {
color: blue !important;
}
...
#example p {
color: red;
}
Another couple suggestions:
Add a span inside of the current. The inner most will win out. Although this could get pretty ugly.
<span class="style21">
<span style="position:absolute;top:432px;left:422px; color:Red" >relating to</span>
</span>
jQuery is also an option. The jQuery library will inject the style attribute in the targeted element.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js" type="text/javascript" ></script>
<script type="text/javascript">
$(document).ready(function() {
$("span").css("color", "#ff0000");
});
</script>
Hope this helps. CSS can be pretty frustrating at times.
I found myself in this situation when I tried to rebase a branch that was tracking a remote branch, and I was trying to rebase it on master. In this scenario if you try to rebase, you'll most likely find your branch diverged and it can create a mess that isn't for git nubees!
Let's say you are on branch my_remote_tracking_branch, which was branched from master
$ git status
# On branch my_remote_tracking_branch
nothing to commit (working directory clean)
And now you are trying to rebase from master as:
git rebase master
STOP NOW and save yourself some trouble! Instead, use merge as:
git merge master
Yes, you'll end up with extra commits on your branch. But unless you are up for "un-diverging" branches, this will be a much smoother workflow than rebasing. See this blog for a much more detailed explanation.
On the other hand, if your branch is only a local branch (i.e. not yet pushed to any remote) you should definitely do a rebase (and your branch will not diverge in this case).
Now if you are reading this because you already are in a "diverged" scenario due to such rebase, you can get back to the last commit from origin (i.e. in an un-diverged state) by using:
git reset --hard origin/my_remote_tracking_branch
SLEEP.exe
is included in most Resource Kits e.g. The Windows Server 2003 Resource Kit which can be installed on Windows XP too.
Usage: sleep time-to-sleep-in-seconds

sleep [-c] commited-memory ratio (1%-100%)
You have to just add the index_col=False
parameter
df1 = pd.read_csv('foo.csv',
header=0,
index_col=False,
names=["dummy", "date", "loc", "x"],
usecols=["dummy", "date", "loc", "x"],
parse_dates=["date"])
print df1
You're using curvy-braces when you should be using parentheses.
A where statement is kept inside a scriptblock, which is defined using curvy baces { }
. To isolate/wrap you tests, you should use parentheses ()
.
I would also suggest trying to do the filtering on the remote computer. Try:
Invoke-Command -computername SERVERNAME {
Get-ChildItem -path E:\dfsroots\datastore2\public |
Where-Object { ($_.extension -eq "xls" -or $_.extension -eq "xlk") -and $_.creationtime -ge "06/01/2014" }

Each XML Web Service needs a unique namespace in order for client applications to distinguish it from other services on the Web. By default, ASP.Net Web Services use http://tempuri.org/ for this purpose. While this suitable for XML Web Services under development, published services should use a unique, permanent namespace.
Your XML Web Service should be identified by a namespace that you control. For example, you can use your company's Internet domain name as part of the namespace. Although many namespaces look like URLs, they need not point to actual resources on the Web.
For XML Web Services creating[sic] using ASP.NET, the default namespace can be changed using the WebService attribute's Namespace property. The WebService attribute is applied to the class that contains the XML Web Service methods. Below is a code example that sets the namespace to "http://microsoft.com/webservices/":
C#
[WebService(Namespace="http://microsoft.com/webservices/")] public class MyWebService { // implementation }
Visual Basic.NET
<WebService(Namespace:="http://microsoft.com/webservices/")> Public Class MyWebService ' implementation End Class
Visual J#.NET
/**@attribute WebService(Namespace="http://microsoft.com/webservices/")*/ public class MyWebService { // implementation }
It's also worth reading section 'A 1.3 Generating URIs' at:
dd-mm-yyyy hh:mm:ss.000 Universal sortable date/time pattern
In your concrete example the problem is that you don't use this construct correctly:
@JsonSubTypes({ @JsonSubTypes.Type(value = MyAbstractClass.class, name = "MyAbstractClass") })
@JsonSubTypes.Type
should contain the actual non-abstract subtypes of your abstract class.
Therefore if you have:
abstract class Parent
and the concrete subclasses
Ch1 extends Parent
and
Ch2 extends Parent
Then your annotation should look like:
@JsonSubTypes({
@JsonSubTypes.Type(value = Ch1.class, name = "ch1"),
@JsonSubTypes.Type(value = Ch2.class, name = "ch2")
})
Here name
should match the value of your 'discriminator':
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME,
include = JsonTypeInfo.As.WRAPPER_OBJECT,
property = "type")
in the property
field, here it is equal to type
. So type
will be the key and the value you set in name
will be the value.
Therefore, when the json string comes if it has this form:
{
"type": "ch1",
"other":"fields"
}
Jackson will automatically convert this to a Ch1
class.
If you send this:
{
"type": "ch2",
"other":"fields"
}
You would get a Ch2
instance.
How about just Dir.mkdir('dir') rescue nil
?
It depends on the nature of the method and how it will be used. If it is normal behavior that the object may not be found, then return null. If it is normal behavior that the object is always found, throw an exception.
As a rule of thumb, use exceptions only for when something exceptional occurs. Don't write the code in such a way that exception throwing and catching is part of its normal operation.
A nested class can have private
, protected
and protected internal
access modifiers along with public
and internal
.
For example, you are implementing the GetEnumerator()
method that returns an IEnumerator<T>
object. The consumers wouldn't care about the actual type of the object. All they know about it is that it implements that interface. The class you want to return doesn't have any direct use. You can declare that class as a private
nested class and return an instance of it (this is actually how the C# compiler implements iterators):
class MyUselessList : IEnumerable<int> {
// ...
private List<int> internalList;
private class UselessListEnumerator : IEnumerator<int> {
private MyUselessList obj;
public UselessListEnumerator(MyUselessList o) {
obj = o;
}
private int currentIndex = -1;
public int Current {
get { return obj.internalList[currentIndex]; }
}
public bool MoveNext() {
return ++currentIndex < obj.internalList.Count;
}
}
public IEnumerator<int> GetEnumerator() {
return new UselessListEnumerator(this);
}
}
Considering current HTML5 standard that introduced sandbox for iframe, all frame busting codes that provided in this page can be disabled when attacker uses sandbox because it restricts the iframe from following:
allow-forms: Allow form submissions.
allow-popups: Allow opening popup windows.
allow-pointer-lock: Allow access to pointer movement and pointer lock.
allow-same-origin: Allow access to DOM objects when the iframe loaded form same origin
allow-scripts: Allow executing scripts inside iframe
allow-top-navigation: Allow navigation to top level window
Please see: http://www.whatwg.org/specs/web-apps/current-work/multipage/the-iframe-element.html#attr-iframe-sandbox
Now, consider attacker used the following code to host your site in iframe:
<iframe src="URI" sandbox></iframe>
Then, all JavaScript frame busting code will fail.
After checking all frame busing code, only this defense works in all cases:
<style id="antiClickjack">body{display:none !important;}</style>
<script type="text/javascript">
if (self === top) {
var antiClickjack = document.getElementById("antiClickjack");
antiClickjack.parentNode.removeChild(antiClickjack);
} else {
top.location = self.location;
}
</script>
that originally proposed by Gustav Rydstedt, Elie Bursztein, Dan Boneh, and Collin Jackson (2010)
This is not a bug- you can only transition on ordinal/calculable properties (an easy way of thinking of this is any property with a numeric start and end number value..though there are a few exceptions).
This is because transitions work by calculating keyframes between two values, and producing an animation by extrapolating intermediate amounts.
visibility
in this case is a binary setting (visible/hidden), so once the transition duration elapses, the property simply switches state, you see this as a delay- but it can actually be seen as the final keyframe of the transition animation, with the intermediary keyframes not having been calculated (what constitutes the values between hidden/visible? Opacity? Dimension? As it is not explicit, they are not calculated).
opacity
is a value setting (0-1), so keyframes can be calculated across the duration provided.
A list of transitionable (animatable) properties can be found here
Handy git alias for looking for unpushed commits in current branch:
alias unpushed = !GIT_CURRENT_BRANCH=$(git name-rev --name-only HEAD) && git log origin/$GIT_CURRENT_BRANCH..$GIT_CURRENT_BRANCH --oneline
What this basically does:
git log origin/branch..branch
but also determines current branch name.
you can also highlight the spaces (replacing the spaces with a block):
:%s/ /¦/g
(before writing undo it)
<iframe id="upload_target" name="upload_target">
<textarea rows="20" cols="100" name="result" id="result" ></textarea>
<input type="text" id="txt1" />
</iframe>
You can Get value by JQuery
$(document).ready(function(){
alert($('#upload_target').contents().find('#result').html());
alert($('#upload_target').contents().find('#txt1').val());
});
work on only same domain link
In modern MongoDB releases you can brute force this with $slice
just off the basic aggregation result. For "large" results, run parallel queries instead for each grouping ( a demonstration listing is at the end of the answer ), or wait for SERVER-9377 to resolve, which would allow a "limit" to the number of items to $push
to an array.
db.books.aggregate([
{ "$group": {
"_id": {
"addr": "$addr",
"book": "$book"
},
"bookCount": { "$sum": 1 }
}},
{ "$group": {
"_id": "$_id.addr",
"books": {
"$push": {
"book": "$_id.book",
"count": "$bookCount"
},
},
"count": { "$sum": "$bookCount" }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 },
{ "$project": {
"books": { "$slice": [ "$books", 2 ] },
"count": 1
}}
])
Still not resolving SERVER-9377, but in this release $lookup
allows a new "non-correlated" option which takes an "pipeline"
expression as an argument instead of the "localFields"
and "foreignFields"
options. This then allows a "self-join" with another pipeline expression, in which we can apply $limit
in order to return the "top-n" results.
db.books.aggregate([
{ "$group": {
"_id": "$addr",
"count": { "$sum": 1 }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 },
{ "$lookup": {
"from": "books",
"let": {
"addr": "$_id"
},
"pipeline": [
{ "$match": {
"$expr": { "$eq": [ "$addr", "$$addr"] }
}},
{ "$group": {
"_id": "$book",
"count": { "$sum": 1 }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 }
],
"as": "books"
}}
])
The other addition here is of course the ability to interpolate the variable through $expr
using $match
to select the matching items in the "join", but the general premise is a "pipeline within a pipeline" where the inner content can be filtered by matches from the parent. Since they are both "pipelines" themselves we can $limit
each result separately.
This would be the next best option to running parallel queries, and actually would be better if the $match
were allowed and able to use an index in the "sub-pipeline" processing. So which is does not use the "limit to $push
" as the referenced issue asks, it actually delivers something that should work better.
You seem have stumbled upon the top "N" problem. In a way your problem is fairly easy to solve though not with the exact limiting that you ask for:
db.books.aggregate([
{ "$group": {
"_id": {
"addr": "$addr",
"book": "$book"
},
"bookCount": { "$sum": 1 }
}},
{ "$group": {
"_id": "$_id.addr",
"books": {
"$push": {
"book": "$_id.book",
"count": "$bookCount"
},
},
"count": { "$sum": "$bookCount" }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 }
])
Now that will give you a result like this:
{
"result" : [
{
"_id" : "address1",
"books" : [
{
"book" : "book4",
"count" : 1
},
{
"book" : "book5",
"count" : 1
},
{
"book" : "book1",
"count" : 3
}
],
"count" : 5
},
{
"_id" : "address2",
"books" : [
{
"book" : "book5",
"count" : 1
},
{
"book" : "book1",
"count" : 2
}
],
"count" : 3
}
],
"ok" : 1
}
So this differs from what you are asking in that, while we do get the top results for the address values the underlying "books" selection is not limited to only a required amount of results.
This turns out to be very difficult to do, but it can be done though the complexity just increases with the number of items you need to match. To keep it simple we can keep this at 2 matches at most:
db.books.aggregate([
{ "$group": {
"_id": {
"addr": "$addr",
"book": "$book"
},
"bookCount": { "$sum": 1 }
}},
{ "$group": {
"_id": "$_id.addr",
"books": {
"$push": {
"book": "$_id.book",
"count": "$bookCount"
},
},
"count": { "$sum": "$bookCount" }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 },
{ "$unwind": "$books" },
{ "$sort": { "count": 1, "books.count": -1 } },
{ "$group": {
"_id": "$_id",
"books": { "$push": "$books" },
"count": { "$first": "$count" }
}},
{ "$project": {
"_id": {
"_id": "$_id",
"books": "$books",
"count": "$count"
},
"newBooks": "$books"
}},
{ "$unwind": "$newBooks" },
{ "$group": {
"_id": "$_id",
"num1": { "$first": "$newBooks" }
}},
{ "$project": {
"_id": "$_id",
"newBooks": "$_id.books",
"num1": 1
}},
{ "$unwind": "$newBooks" },
{ "$project": {
"_id": "$_id",
"num1": 1,
"newBooks": 1,
"seen": { "$eq": [
"$num1",
"$newBooks"
]}
}},
{ "$match": { "seen": false } },
{ "$group":{
"_id": "$_id._id",
"num1": { "$first": "$num1" },
"num2": { "$first": "$newBooks" },
"count": { "$first": "$_id.count" }
}},
{ "$project": {
"num1": 1,
"num2": 1,
"count": 1,
"type": { "$cond": [ 1, [true,false],0 ] }
}},
{ "$unwind": "$type" },
{ "$project": {
"books": { "$cond": [
"$type",
"$num1",
"$num2"
]},
"count": 1
}},
{ "$group": {
"_id": "$_id",
"count": { "$first": "$count" },
"books": { "$push": "$books" }
}},
{ "$sort": { "count": -1 } }
])
So that will actually give you the top 2 "books" from the top two "address" entries.
But for my money, stay with the first form and then simply "slice" the elements of the array that are returned to take the first "N" elements.
The demonstration code is appropriate for usage with current LTS versions of NodeJS from v8.x and v10.x releases. That's mostly for the async/await
syntax, but there is nothing really within the general flow that has any such restriction, and adapts with little alteration to plain promises or even back to plain callback implementation.

Not to raise the dead after more than a year, but all the previous answers miss some crucial points:
@EnableWebMvc
on your class will disable org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration
. That's fine if you want complete control but otherwise, it's a problem.There's no need to write any code to add another location for static resources in addition to what is already provided. Looking at org.springframework.boot.autoconfigure.web.ResourceProperties
from v1.3.0.RELEASE, I see a field staticLocations
that can be configured in the application.properties
. Here's a snippet from the source:
/**
* Locations of static resources. Defaults to classpath:[/META-INF/resources/,
* /resources/, /static/, /public/] plus context:/ (the root of the servlet context).
*/
private String[] staticLocations = RESOURCE_LOCATIONS;
As mentioned before, the request URL will be resolved relative to these locations. Thus src/main/resources/static/index.html
will be served when the request URL is /index.html
. The class that is responsible for resolving the path, as of Spring 4.1, is org.springframework.web.servlet.resource.PathResourceResolver
.
Suffix pattern matching is enabled by default which means for a request URL /index.html
, Spring is going to look for handlers corresponding to /index.html
. This is an issue if the intention is to serve static content. To disable that, extend WebMvcConfigurerAdapter
(but don't use @EnableWebMvc
) and override configurePathMatch
as shown below:
@Override
public void configurePathMatch(PathMatchConfigurer configurer) {
super.configurePathMatch(configurer);
configurer.setUseSuffixPatternMatch(false);
}
IMHO, the only way to have fewer bugs in your code is not to write code whenever possible. Use what is already provided, even if that takes some research, the return is worth it.
I really liked these articles:
He really dumbs down the concept in a humorous way. Worth reading.
The JAVA_HOME should point to the JDK home rather than the JRE home if you are going to be compiling stuff, likewise - I would try and install the JDK in a directory that doesn't include a space. Even if this is not your problem now, it can cause problems in the future!

Add the permissions to the app manifest
Add one of the following permissions as a child of the element in your Android manifest. Either the coarse location permission:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp" >
...
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
...
</manifest>
Or the fine location permission:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp" >
...
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
...
</manifest>
The following code sample checks for permission using the Support library before enabling the My Location layer:
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
mMap.setMyLocationEnabled(true);
} else {
// Show rationale and request permission.
}
The following sample handles the result of the permission request by implementing the ActivityCompat.OnRequestPermissionsResultCallback from the Support library:
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
if (requestCode == MY_LOCATION_REQUEST_CODE) {
if (permissions.length == 1 &&
permissions[0] == Manifest.permission.ACCESS_FINE_LOCATION &&
grantResults[0] == PackageManager.PERMISSION_GRANTED) {
mMap.setMyLocationEnabled(true);
} else {
// Permission was denied. Display an error message.
}
}
This example provides current location update using GPS provider. Entire Android app code is as follows,

import android.location.LocationManager;
import android.widget.TextView;
import android.util.Log;
public class MainActivity extends Activity implements LocationListener{
protected LocationManager locationManager;
protected LocationListener locationListener;
protected Context context;
TextView txtLat;
String lat;
String provider;
protected String latitude,longitude;
protected boolean gps_enabled,network_enabled;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txtLat = (TextView) findViewById(R.id.textview1);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
}
@Override
public void onLocationChanged(Location location) {
txtLat = (TextView) findViewById(R.id.textview1);
txtLat.setText("Latitude:" + location.getLatitude() + ", Longitude:" + location.getLongitude());
}
@Override
public void onProviderDisabled(String provider) {
Log.d("Latitude","disable");
}
@Override
public void onProviderEnabled(String provider) {
Log.d("Latitude","enable");
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.d("Latitude","status");
}
}

Use CSS cursor: pointer
if I remember correctly.
Either in your CSS file:
.link_cursor
{
cursor: pointer;
}
Then just add the following HTML to any elements you want to have the link cursor: class="link_cursor"
(the preferred method.)
Or use inline CSS:
<a style="cursor: pointer;">

Schema is a way of categorising the objects in a database. It can be useful if you have several applications share a single database and while there is some common set of data that all application accesses.
I'm not sure that I understand what you mean by "rights of ownership".
If User B owns a stored procedure, User B can grant User A permission to run the stored procedure
GRANT EXECUTE ON b.procedure_name TO a
User A would then call the procedure using the fully qualified name, i.e.
BEGIN
b.procedure_name( <<list of parameters>> );
END;
Alternately, User A can create a synonym in order to avoid having to use the fully qualified procedure name.
CREATE SYNONYM procedure_name FOR b.procedure_name;
BEGIN
procedure_name( <<list of parameters>> );
END;

I wrote a useful store procedure to help identify and resolve the problem of text truncation (String or binary data would be truncated) when the INSERT SELECT statement is used. It compares fields CHAR, VARCHAR, NCHAR AND NVARCHAR only and returns an evaluation field by field in case of being the possible cause of the error.
EXEC dbo.GetFieldStringTruncate SourceTableName, TargetTableName
This stored procedure is oriented to the problem of text truncation when an INSERT SELECT statement is made.
The operation of this stored procedure depends on the user previously identifying the INSERT statement with the problem. Then inserting the source data into a global temporary table. The SELECT INTO statement is recommended.
You must use the same name of the field of the destination table in the alias of each field of the SELECT statement.

Description:
Syntax
---------------
dbo.GetFieldStringTruncate(SourceTable, TargetTable)
+---------------------------+-----------------------+
| SourceTableName | VARCHAR(255) |
+---------------------------+-----------------------+
| TargetTableName | VARCHAR(255) |
+---------------------------+-----------------------+
Arguments
---------------
SourceTableName
The name of the source table. It should be a temporary table using double charp '##'. E.g. '##temp'
TargetTableName
The name of the target table. It is the table that receives the data used in the INSERT INTO stament.
Return Type
----------------
Returns a table with a list of all the fields with the type defined as text and performs an evaluation indicating which field would present the problem of string truncation.
Remarks
----------------
This stored procedure is oriented to the problem of text truncation when an INSERT SELECT statement is made.
The operation of this stored procedure depends on the user previously identifying the INSERT statement with the problem. Then inserting the source data into a global temporary table. The SELECT INTO statement is recommended.
You must use the same name of the field of the destination table in the alias of each field of the SELECT statement.
Examples

For now only supports the data types CHAR, VARCHAR, NCHAR and NVARCHAR. You can find the last versión of this code in the next link below and we help each other to improve it. GetFieldStringTruncate.sql

You can use jQuery's getJSON() or Load(); with the latter, you can reference an existing html file. For more details, see http://www.codeproject.com/Articles/661782/Three-Ways-to-Dynamically-Load-HTML-Content-into-a
In case you dont need the message body in html, turn it off:
message.IsBodyHtml = false;
then use e.g:
message.Body = "First line" + Environment.NewLine +
"Second line";
but if you need to have it in html for some reason, use the html-tag:
message.Body = "First line <br /> Second line";
You can do the following fix for removing Whitespaces with trim and @ symbol:
var result = string.replace(/ /g, ''); // Remove whitespaces with trimmed value
var result = string.replace(/ /g, '@'); // Remove whitespaces with *@* symbol
A minor additional points worth mentioning. If you have a very large file you can on the fly calculate the number of rows (if no header) using (where bedGraph
is the name of your file in your working directory):
>numRow=as.integer(system(paste("wc -l", bedGraph, "| sed 's/[^0-9.]*\\([0-9.]*\\).*/\\1/'"), intern=T))
You can then use that either in read.csv
, read.table
...
>system.time((BG=read.table(bedGraph, nrows=numRow, col.names=c('chr', 'start', 'end', 'score'),colClasses=c('character', rep('integer',3)))))

One reason to choose .keystore over .jks is that Unity recognizes the former but not the latter when you're navigating to select your keystore file (Unity 2017.3, macOS).
This should help:
function isNumber(n) {
return !isNaN(parseFloat(n)) && isFinite(n);
}
Very good link: Validate decimal numbers in JavaScript - IsNumeric()
You can find the default Android menu icons here - link is broken now.
Update: You can find Material Design icons here.
In .net2.0 you can use the variable Application.UserAppDataPath
Personally, I'd code it as tinyint and:
Reasons:
It will take on average 8 bytes to store text, 1 byte for tinyint. Over millions of rows, this will make a difference.
What about collation? Is "Daily" the same as "DAILY"? It takes resources to do this kind of comparison.
Finally, what if you want to add "Biweekly" or "Hourly"? This requires a schema change when you could just add new rows to a lookup table.
It would probably be easier to just fake it by using a div. Just make sure you set the height if its empty so that it can actually appear. Say for instance you want it to be 50px tall set the div height to 50px.
<div id="rightflower">
<div id="divImg"></div>
</div>
And in your style sheet just add the background and its properties, height and width, and what ever positioning you had in mind.
You can use javascript's indexOf function.
var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";
if(str1.indexOf(str2) != -1){
alert(str2 + " found");
}
It appears you could use a list
instead of a tuple
.
This becomes more important I think when you are grabbing attributes instead of 'magic indexes' of a list/tuple.
In my case I wanted to sort by multiple attributes of a class, where the incoming keys were strings. I needed different sorting in different places, and I wanted a common default sort for the parent class that clients were interacting with; only having to override the 'sorting keys' when I really 'needed to', but also in a way that I could store them as lists that the class could share
So first I defined a helper method
def attr_sort(self, attrs=['someAttributeString']:
'''helper to sort by the attributes named by strings of attrs in order'''
return lambda k: [ getattr(k, attr) for attr in attrs ]
then to use it
# would defined elsewhere but showing here for consiseness
self.SortListA = ['attrA', 'attrB']
self.SortListB = ['attrC', 'attrA']
records = .... #list of my objects to sort
records.sort(key=self.attr_sort(attrs=self.SortListA))
# perhaps later nearby or in another function
more_records = .... #another list
more_records.sort(key=self.attr_sort(attrs=self.SortListB))
This will use the generated lambda function sort the list by object.attrA
and then object.attrB
assuming object
has a getter corresponding to the string names provided. And the second case would sort by object.attrC
then object.attrA
.
This also allows you to potentially expose outward sorting choices to be shared alike by a consumer, a unit test, or for them to perhaps tell you how they want sorting done for some operation in your api by only have to give you a list and not coupling them to your back end implementation.

Try Ctrl + F5 in Visual Studio to run your program, this will add a pause with "Press any key to continue..." automatically without any Console.Readline() or ReadKey() functions.
I prefer using Math.Round, Math.Floor, Math.Ceiling or Math.Truncate to explicitly set the rounding mode as appropriate.
Note that they all return Decimal as well - since Decimal has a larger range of values than an Int32, so you'll still need to cast (and check for overflow/underflow).
checked {
int i = (int)Math.Floor(d);
}
I just crafted this as I needed a good, simple way.
If it gets to the final digit, and if it is a zero, it will stay.
You could also use a foreach loop instead for super long strings.
I just replace each leading oldChar with the newChar.
This is great for a problem I just solved, after formatting an int into a string.
/* Like this: */
int counterMax = 1000;
int counter = ...;
string counterString = counter.ToString($"D{counterMax.ToString().Length}");
counterString = RemoveLeadingChars('0', ' ', counterString);
string fullCounter = $"({counterString}/{counterMax})";
// = ( 1/1000) ... ( 430/1000) ... (1000/1000)
static string RemoveLeadingChars(char oldChar, char newChar, char[] chars)
{
string result = "";
bool stop = false;
for (int i = 0; i < chars.Length; i++)
{
if (i == (chars.Length - 1)) stop = true;
if (!stop && chars[i] == oldChar) chars[i] = newChar;
else stop = true;
result += chars[i];
}
return result;
}
static string RemoveLeadingChars(char oldChar, char newChar, string text)
{
return RemoveLeadingChars(oldChar, newChar, text.ToCharArray());
}
I always tend to make my functions suitable for my own library, so there are options.
For completeness sake, the BeautifulSoup 4 version, making use of the encoding supplied by the server as well:
from bs4 import BeautifulSoup
import urllib.request
parser = 'html.parser' # or 'lxml' (preferred) or 'html5lib', if installed
resp = urllib.request.urlopen("http://www.gpsbasecamp.com/national-parks")
soup = BeautifulSoup(resp, parser, from_encoding=resp.info().get_param('charset'))
for link in soup.find_all('a', href=True):
print(link['href'])
or the Python 2 version:
from bs4 import BeautifulSoup
import urllib2
parser = 'html.parser' # or 'lxml' (preferred) or 'html5lib', if installed
resp = urllib2.urlopen("http://www.gpsbasecamp.com/national-parks")
soup = BeautifulSoup(resp, parser, from_encoding=resp.info().getparam('charset'))
for link in soup.find_all('a', href=True):
print link['href']
and a version using the requests
library, which as written will work in both Python 2 and 3:
from bs4 import BeautifulSoup
from bs4.dammit import EncodingDetector
import requests
parser = 'html.parser' # or 'lxml' (preferred) or 'html5lib', if installed
resp = requests.get("http://www.gpsbasecamp.com/national-parks")
http_encoding = resp.encoding if 'charset' in resp.headers.get('content-type', '').lower() else None
html_encoding = EncodingDetector.find_declared_encoding(resp.content, is_html=True)
encoding = html_encoding or http_encoding
soup = BeautifulSoup(resp.content, parser, from_encoding=encoding)
for link in soup.find_all('a', href=True):
print(link['href'])
The soup.find_all('a', href=True)
call finds all <a>
elements that have an href
attribute; elements without the attribute are skipped.
BeautifulSoup 3 stopped development in March 2012; new projects really should use BeautifulSoup 4, always.
Note that you should leave decoding the HTML from bytes to BeautifulSoup. You can inform BeautifulSoup of the characterset found in the HTTP response headers to assist in decoding, but this can be wrong and conflicting with a <meta>
header info found in the HTML itself, which is why the above uses the BeautifulSoup internal class method EncodingDetector.find_declared_encoding()
to make sure that such embedded encoding hints win over a misconfigured server.
With requests
, the response.encoding
attribute defaults to Latin-1 if the response has a text/*
mimetype, even if no characterset was returned. This is consistent with the HTTP RFCs but painful when used with HTML parsing, so you should ignore that attribute when no charset
is set in the Content-Type header.
To watch out the runtime changes in value of a custom directive, use $observe
method of attrs
object, instead of putting $watch
inside a custom directive.
Here is the documentation for the same ... $observe docs
I think is better put the token in the form, and get this token by id
<input type="hidden" name="_token" id="token" value="{{ csrf_token() }}">
And the JQUery :
var data = {
"_token": $('#token').val()
};
this way, your JS don't need to be in your blade files.
Most of the time spinner.setSelection(i); //i is 0 to (size-1) of adapter's size
doesn't work. If you just call spinner.setSelection(i);
It depends on your logic.
If view is fully loaded and you want to call it from interface I suggest you to call
spinner.setAdapter(spinner_no_of_hospitals.getAdapter());
spinner.setSelection(i); // i is 0 or within adapter size
Or if you want to change between activity/fragment lifecycle, call like this
spinner.post(new Runnable() {
@Override public void run() {
spinner.setSelection(i);
}
});
Often the complete testImplementation
, implementation
, and androidTestImplementation
dependency graph is too much to examine together. If you merely want the implementation
dependency graph you can use:
./gradlew app:dependencies --configuration implementation
Source: Gradle docs section 4.7.6
Note: compile
has been deprecated in more recent versions of Gradle and in more recent versions you are advised to shift all of your compile
dependencies to implementation

Thanks storsoc!
All the best to you all and have a nice day!
If this is your detail.html
I don't see where do you load detail.js
?
Maybe this
<script src="js/index.js"></script>
should be this
<script src="js/detail.js"></script>
?
you don't need to set the width of header in css, just put the background image as center using this code:
background: url("images/logo.png") no-repeat top center;
or you can just use img
tag and put align="center"
in the div
You can invoke reflections and also, set order of sequence for getter for values through annotations

There is no difference between using OR ; i.e. it is a convention used by C++ programmers. I myself prefer as it more clearly describes it use; i.e. defining a template with a specific type :)
Note: There is one exception where you do have to use class (and not typename) when declaring a template template parameter:
template <template class T> class C { }; // valid!
template <template typename T> class C { }; // invalid!
In most cases, you will not be defining a nested template definition, so either definition will work -- just be consistent in your use...
Another great way of solving it while using a model is by using the values()
function.
def returnResponse(date):
response = ScheduledDate.objects.filter(date__startswith=date).values()
return Response(response)
As quoted by the FAQ, you should call the destructor explicitly when using placement new.
This is about the only time you ever explicitly call a destructor.
I agree though that this is seldom needed.
var r = confirm('Want to delete ?');
if (r == true) {
$('#admin-category-destroy').submit();
}
The other answers involving RTTI (typeid) are probably what you want, as long as:
The alternative, (similar to Greg Hewgill's answer), is to build a compile-time table of traits.
template <typename T> struct type_as_string;
// declare your Wibble type (probably with definition of Wibble)
template <>
struct type_as_string<Wibble>
{
static const char* const value = "Wibble";
};
Be aware that if you wrap the declarations in a macro, you'll have trouble declaring names for template types taking more than one parameter (e.g. std::map), due to the comma.
To access the name of the type of a variable, all you need is
template <typename T>
const char* get_type_as_string(const T&)
{
return type_as_string<T>::value;
}
Put a Console.Read() as the last line in your program. That will prevent it from closing until you press a key
static void Main(string[] args)
{
StringAddString s = new StringAddString();
Console.Read();
}
DateTime.FromFileTime
should do the trick:
PS C:\> [datetime]::FromFileTime(129948127853609000)
Monday, October 15, 2012 3:13:05 PM
Then depending on how you want to format it, check out standard and custom datetime format strings.
PS C:\> [datetime]::FromFileTime(129948127853609000).ToString('d MMMM')
15 October
PS C:\> [datetime]::FromFileTime(129948127853609000).ToString('g')
10/15/2012 3:13 PM
If you want to integrate this into your one-liner, change your select
statement to this:
... | Select Name, manager, @{N='LastLogon'; E={[DateTime]::FromFileTime($_.LastLogon)}} | ...
Use Mark Longair's answer, but make sure to use the HTTPS link to the repository:
git remote set-url origin https://github.com/my_user_name/my_repo.git
You can use then git push origin master
.
Depends on the database server. MySQL
doesn't care, its basically the same thing.
Oracle
, DB2
, and other enterprise level database solutions make a distinction. Usually a schema is a collection of tables and a Database is a collection of schemas.
Try using:
from cv2 import cv
It works for me.
background-attachment:fixed
in IOS Safari has been a known bug for as long as I can recall.
Here's some other options for you:
https://stackoverflow.com/a/23420490/1004312
Since the fixed position in general is not all that stable on touch (some more than others, Chrome works great), it is still acting up in Safari IOS 8 in situations that used to work in IOS 7, therefore I generally just use JS to detect touch devices, including Windows mobile.
/* ============== SUPPORTS TOUCH OR NOT ========= */

var supports = (function() {
var d = document.documentElement,
c = "ontouchstart" in window || navigator.msMaxTouchPoints;
if (c) {
d.className += " touch";
return {
touch: true
}
} else {
d.className += " no-touch";
return {
touch: false
}
}
})();
CSS example assumes mobile first:
.myBackgroundPrecious {
background: url(1.jpg) no-repeat center center;
background-size: cover;
}
.no-touch .myBackgroundPrecious {

Following code shows how to upload a file to a SFTP server using our Rebex SFTP component.
// create client, connect and log in
Sftp client = new Sftp();
client.Connect(hostname);
client.Login(username, password);
// upload the 'test.zip' file to the current directory at the server
client.PutFile(@"c:\data\test.zip", "test.zip");
client.Disconnect();
You can write a complete communication log to a file using a LogWriter property as follows. Examples output (from FTP component but the SFTP output is similar) can be found here.
client.LogWriter = new Rebex.FileLogWriter(
@"c:\temp\log.txt", Rebex.LogLevel.Debug);
or intercept the communication using events as follows:
Sftp client = new Sftp();
client.CommandSent += new SftpCommandSentEventHandler(client_CommandSent);
client.ResponseRead += new SftpResponseReadEventHandler(client_ResponseRead);
client.Connect("sftp.example.org");
//...
private void client_CommandSent(object sender, SftpCommandSentEventArgs e)
{
Console.WriteLine("Command: {0}", e.Command);
}
private void client_ResponseRead(object sender, SftpResponseReadEventArgs e)
{
Console.WriteLine("Response: {0}", e.Response);
}

Use the .clone() method on your List. It will return a shallow copy, meaning that it will contain pointers to the same objects, so you won't have to copy the list. Then just use Collections.
Ergo,
Collections.reverse(list.clone());
If you are using a List
and don't have access to clone()
you can use subList()
:
List<?> shallowCopy = list.subList(0, list.size());
Collections.reverse(shallowCopy);
execute below line before creating table : SET FOREIGN_KEY_CHECKS = 0;
FOREIGN_KEY_CHECKS option specifies whether or not to check foreign key constraints for InnoDB tables.
-- Specify to check foreign key constraints (this is the default)
SET FOREIGN_KEY_CHECKS = 1;
-- Do not check foreign key constraints
SET FOREIGN_KEY_CHECKS = 0;
When to Use : Temporarily disabling referential constraints (set FOREIGN_KEY_CHECKS to 0) is useful when you need to re-create the tables and load data in any parent-child order
After setting up GOPRIVATE
and git config ...
People may still meeting problems like this when fetching private source:
https fetch: Get "https://private/user/repo?go-get=1": EOF
They can't use private repo without .git
extension.
The reason is the go tool has no idea about the VCS protocol of this repo, git
or svn
or any other, unlike github.com
or golang.org
them are hardcoded into go's source.
Then the go tool will do a https
query before fetching your private repo:
https://private/user/repo?go-get=1
If your private repo has no support for https
request, please use replace
to tell it directly :
require private/user/repo v1.0.0
...
replace private/user/repo => private.server/user/repo.git v1.0.0
If someone is searching for a complete solution for changing default charset for all database tables and converting the data, this could be one:
DELIMITER $$
CREATE PROCEDURE `exec_query`(IN sql_text VARCHAR(255))
BEGIN
SET @tquery = `sql_text`;
PREPARE `stmt` FROM @tquery;
EXECUTE `stmt`;
DEALLOCATE PREPARE `stmt`;
END$$
CREATE PROCEDURE `change_character_set`(IN `charset` VARCHAR(64), IN `collation` VARCHAR(64))
BEGIN
DECLARE `done` BOOLEAN DEFAULT FALSE;
DECLARE `tab_name` VARCHAR(64);
DECLARE `charset_cursor` CURSOR FOR
SELECT `table_name` FROM `information_schema`.`tables`
WHERE `table_schema` = DATABASE() AND `table_type` = 'BASE TABLE';
DECLARE CONTINUE HANDLER FOR NOT FOUND SET `done` = TRUE;
SET foreign_key_checks = 0;
OPEN `charset_cursor`;
`change_loop`: LOOP
FETCH `charset_cursor` INTO `tab_name`;
IF `done` THEN
LEAVE `change_loop`;
END IF;
CALL `exec_query`(CONCAT(
'ALTER TABLE `',
tab_name,
'` CONVERT TO CHARACTER SET ',
QUOTE(charset),
' COLLATE ',
QUOTE(collation),
';'
));
CALL `exec_query`(CONCAT('REPAIR TABLE `', tab_name, '`;'));
CALL `exec_query`(CONCAT('OPTIMIZE TABLE `', tab_name, '`;'));
END LOOP `change_loop`;
CLOSE `charset_cursor`;
SET foreign_key_checks = 1;
END$$
DELIMITER ;
You can place this code inside the file e.g. chg_char_set.sql
and execute it e.g. by calling it from MySQL terminal:
SOURCE ~/path-to-the-file/chg_char_set.sql
Then call defined procedure with desired input parameters e.g.
CALL change_character_set('utf8mb4', 'utf8mb4_bin');
Once you've tested the results, you can drop those stored procedures:
DROP PROCEDURE `change_character_set`;
DROP PROCEDURE `exec_query`;
If your threads are performing any kind of resource-intensive work (CPU/Disk) then you'll rarely see benefits beyond one or two, and too many will kill performance very quickly.
The 'best-case' is that your later threads will stall while the first ones complete, or some will have low-overhead blocks on resources with low contention. Worst-case is that you start thrashing the cache/disk/network and your overall throughput drops through the floor.
A good solution is to place requests in a pool that are then dispatched to worker threads from a thread-pool (and yes, avoiding continuous thread creation/destruction is a great first step).
The number of active threads in this pool can then be tweaked and scaled based on the findings of your profiling, the hardware you are running on, and other things that may be occurring on the machine.
This worked for me-

If you really want to run Jenkins as you, I suggest you check out my Jenkins.app. An alternative, easy way to run Jenkins on Mac.

Rather than keeping everything string-based, you should use a class which is designed to represent a file system path.
If you're using Java 7 or Java 8, you should strongly consider using java.nio.file.Path
; Path.resolve
can be used to combine one path with another, or with a string. The Paths
helper class is useful too. For example:
Path path = Paths.get("foo", "bar", "baz.txt");
If you need to cater for pre-Java-7 environments, you can use java.io.File
, like this:
File baseDirectory = new File("foo");
File subDirectory = new File(baseDirectory, "bar");
File fileInDirectory = new File(subDirectory, "baz.txt");
If you want it back as a string later, you can call getPath()
. Indeed, if you really wanted to mimic Path.Combine
, you could just write something like:
public static String combine(String path1, String path2)
{
File file1 = new File(path1);
File file2 = new File(file1, path2);
return file2.getPath();
}
@[User::path] ="MDS/Material/"+(DT_STR, 4, 1252) DATEPART("yy" , GETDATE())+ "/" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2) + "/" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2)
This is my specific example to read multiple files and combine them into 1 data frame:
path<- file.path("C:/folder/subfolder")
files <- list.files(path=path, pattern="/*.csv",full.names = T)
library(data.table)
data = do.call(rbind, lapply(files, function(x) read.csv(x, stringsAsFactors = FALSE)))
void foo<TOne, TTwo>()
where TOne : BaseOne
where TTwo : BaseTwo

If css3 is an option, this can be done using the css calc()
function.
Markup is simple - a bunch of divs with some container element.
CSS looks like this:
div
{
height: 100px;
float: left;
background:pink;
width: 50px;
margin-right: calc((100% - 300px) / 5 - 1px);
}
div:last-child
{
margin-right:0;
}
where -1px to fix an IE9+ calc/rounding bug - see here
Here, in addition to the calc()
function, media queries
are necessary.
The basic idea is to set up a media query for each #columns states, where I then use calc() to work out the margin-right on each of the elements (except the ones in the last column).
This sounds like a lot of work, but if you're using LESS or SASS this can be done quite easily
(It can still be done with regular css, but then you'll have to do all the calculations manually, and then if you change your box width - you have to work out everything again)
Below is an example using LESS: (You can copy/paste this code here to play with it, [it's also the code I used to generate the above mentioned fiddle])
@min-margin: 15px;
@div-width: 150px;
@3divs: (@div-width * 3);
@4divs: (@div-width * 4);
@5divs: (@div-width * 5);
@6divs: (@div-width * 6);
@7divs: (@div-width * 7);
@3divs-width: (@3divs + @min-margin * 2);
@4divs-width: (@4divs + @min-margin * 3);
@5divs-width: (@5divs + @min-margin * 4);
@6divs-width: (@6divs + @min-margin * 5);
@7divs-width: (@7divs + @min-margin * 6);
*{margin:0;padding:0;}
.container
{
overflow: auto;
display: block;
min-width: @3divs-width;
}
.container > div
{
margin-bottom: 20px;
width: @div-width;
height: 100px;
background: blue;
float:left;
color: #fff;
text-align: center;
}
@media (max-width: @3divs-width) {
.container > div {
margin-right: @min-margin;
}
.container > div:nth-child(3n) {
margin-right: 0;
}
}
@media (min-width: @3divs-width) and (max-width: @4divs-width) {
.container > div {
margin-right: ~"calc((100% - @{3divs})/2 - 1px)";
}
.container > div:nth-child(3n) {
margin-right: 0;
}
}
@media (min-width: @4divs-width) and (max-width: @5divs-width) {
.container > div {
margin-right: ~"calc((100% - @{4divs})/3 - 1px)";
}
.container > div:nth-child(4n) {
margin-right: 0;
}
}
@media (min-width: @5divs-width) and (max-width: @6divs-width) {
.container > div {
margin-right: ~"calc((100% - @{5divs})/4 - 1px)";
}
.container > div:nth-child(5n) {
margin-right: 0;
}
}
@media (min-width: @6divs-width){
.container > div {
margin-right: ~"calc((100% - @{6divs})/5 - 1px)";
}
.container > div:nth-child(6n) {
margin-right: 0;
}
}
So basically you first need to decide a box-width and a minimum margin that you want between the boxes.
With that, you can work out how much space you need for each state.
Then, use calc() to calcuate the right margin, and nth-child to remove the right margin from the boxes in the final column.
The advantage of this answer over the accepted answer which uses text-align:justify
is that when you have more than one row of boxes - the boxes on the final row don't get 'justified' eg: If there are 2 boxes remaining on the final row - I don't want the first box to be on the left and the next one to be on the right - but rather that the boxes follow each other in order.
Regarding browser support: This will work on IE9+,Firefox,Chrome,Safari6.0+ - (see here for more details) However i noticed that on IE9+ there's a bit of a glitch between media query states. [if someone knows how to fix this i'd really like to know :) ] <-- FIXED HERE

}

The best way (actually the only way*) to simulate an actual click event using only CSS (rather than just hovering on an element or making an element active, where you don't have mouseUp) is to use the checkbox hack. It works by attaching a label
to an <input type="checkbox">
element via the label's for=""
attribute.
This feature has broad browser support (the :checked
pseudo-class is IE9+).
Apply the same value to an <input>
's ID attribute and an accompanying <label>
's for=""
attribute, and you can tell the browser to re-style the label on click with the :checked
pseudo-class, thanks to the fact that clicking a label will check and uncheck the "associated" <input type="checkbox">
.
* You can simulate a "selected" event via the :active
or :focus
pseudo-class in IE7+ (e.g. for a button that's normally 50px
wide, you can change its width while active
: #btnControl:active { width: 75px; }
), but those are not true "click" events. They are "live" the entire time the element is selected (such as by Tabbing with your keyboard), which is a little different from a true click event, which fires an action on - typically - mouseUp
.
label {
display: block;
background: lightgrey;
width: 100px;
height: 100px;
}
#demo:checked + label {
background: blue;
color: white;
}
_x000D_
<input type="checkbox" id="demo"/>
<label for="demo">I'm a square. Click me.</label>
_x000D_
Here I've positioned the label right after the input in my markup. This is so that I can use the adjacent sibling selector (the + key) to select only the label that immediately follows my #demo
checkbox. Since the :checked
pseudo-class applies to the checkbox, #demo:checked + label
will only apply when the checkbox is checked.
#btnControl {
display: none;
}
#btnControl:checked + label > img {
width: 70px;
height: 74px;
}
_x000D_
<input type="checkbox" id="btnControl"/>
<label class="btn" for="btnControl"><img src="https://placekitten.com/200/140" id="btnLeft" /></label>
_x000D_
With that being said, there is some bad news. Because a label can only be associated with one form control at a time, that means you can't just drop a button inside the <label></label>
tags and call it a day. However, we can use some CSS to make the label look and behave fairly close to how an HTML button looks and behaves.
#btnControl {
display: none;
}
.btn {
width: 60px;
height: 20px;
background: silver;
border-radius: 5px;
padding: 1px 3px;
box-shadow: 1px 1px 1px #000;
display: block;
text-align: center;
background-image: linear-gradient(to bottom, #f4f5f5, #dfdddd);
font-family: arial;
font-size: 12px;
line-height:20px;
}
.btn:hover {
background-image: linear-gradient(to bottom, #c3e3fa, #a5defb);
}
.btn:active {
margin-left: 1px 1px 0;
box-shadow: -1px -1px 1px #000;
outline: 1px solid black;
-moz-outline-radius: 5px;
background-image: linear-gradient(to top, #f4f5f5, #dfdddd);
}
#btnControl:checked + label {
width: 70px;
height: 74px;
line-height: 74px;
}
_x000D_
<input type="checkbox" id="btnControl"/>
<label class="btn" for="btnControl">Click me!</label>
_x000D_
Most of the CSS in this demo is just for styling the label element. If you don't actually need a button, and any old element will suffice, then you can remove almost all of the styles in this demo, similar to my second demo above.
You'll also notice I have one prefixed property in there, -moz-outline-radius
. A while back, Mozilla added this awesome non-spec property to Firefox, but the folks at WebKit decided they aren't going to add it, unfortunately. So consider that line of CSS just a progressive enhancement for people who use Firefox.
Reinstall JDK and set system variable JAVA_HOME on your JDK. (e.g. C:\tools\jdk7)
And add JAVA_HOME variable to your PATH system variable
Type in command line
echo %JAVA_HOME%
and
java -version
To verify whether your installation was done successfully.
This problem generally occurs in Windows when your "Java Runtime Environment" registry entry is missing or mismatched with the installed JDK. The mismatch can be due to multiple JDKs.
Steps to resolve:
Open the Run window:
Press windows+R
Open registry window:
Type regedit
and enter.
Go to: \HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\
If Java Runtime Environment is not present inside JavaSoft, then create a new Key and give the name Java Runtime Environment.
For Java Runtime Environment create "CurrentVersion" String Key and give appropriate version as value:
Create a new subkey of 1.8.
For 1.8 create a String Key with name JavaHome with the value of JRE home:

Well to obtain all different values in a Dataframe
you can use distinct. As you can see in the documentation that method returns another DataFrame
. After that you can create a UDF
in order to transform each record.
For example:
val df = sc.parallelize(Array((1, 2), (3, 4), (1, 6))).toDF("age", "salary")
// I obtain all different values. If you show you must see only {1, 3}
val distinctValuesDF = df.select(df("age")).distinct
// Define your udf. In this case I defined a simple function, but they can get complicated.
val myTransformationUDF = udf(value => value / 10)
// Run that transformation "over" your DataFrame
val afterTransformationDF = distinctValuesDF.select(myTransformationUDF(col("age")))
See the documentation events section
Depending on the version, one of the snippets below should give you the event you want, alternatively just replace "select2-selecting" with "change".
Version 4.0 +
Events are now in format: select2:selecting
(instead of select2-selecting
)
Thanks to snakey for the notification that this has changed as of 4.0
$('#yourselect').on("select2:selecting", function(e) {
// what you would like to happen
});
Version Before 4.0
$('#yourselect').on("select2-selecting", function(e) {
// what you would like to happen
});
Just to clarify, the documentation for select2-selecting
reads:
select2-selecting Fired when a choice is being selected in the dropdown, but before any modification has been made to the selection. This event is used to allow the user to reject selection by calling event.preventDefault()
whereas change has:
change Fired when selection is changed.
So change
may be more appropriate for your needs, depending on whether you want the selection to complete and then do your event, or potentially block the change.
Have you tried os.mkdir?
You might also try this little code snippet:

I would have tagged this as a comment but cant (dont have the rep) just wanted to thank Tilman. I was trying to get PDFsam (PDF Split and Merge) to work to no avail.
At launch it would produce an error stating that it could not find JRE 1.6.0. I Have both 32 and 64 bit versions and they check out fine at the java website in their respective browsers.
Tried uninstalling/reinstalling and rebooting repeatedly as well as using JavaRa. No such luck, still no go.
I looked in the registry after reading this post and there was no ...\SOFTWARE\JavaSoft\ key so I added each with their respective string values pointing to my x86 version (PDFsam is a 32bit program). This got past the first problem but an error popped up about amd64 libraries suggesting the machine wanted to run the 64bit version. So I changed the paths to the 64bit JRE and PDFsam now works.
FYI - I got here by searching for Java registry keys after I was unable to launch javaw.exe from command prompt (even after adding the requisite paths to system path), making the aforementioned changes solved this as well.
There is another working example with some my comments :
List<MimePart> mimeParts = new List<MimePart>();
try
{
foreach (string key in form.AllKeys)
{
StringMimePart part = new StringMimePart();
part.Headers["Content-Disposition"] = "form-data; name=\"" + key + "\"";
part.StringData = form[key];
mimeParts.Add(part);
}
int nameIndex = 0;
foreach (UploadFile file in files)
{
StreamMimePart part = new StreamMimePart();
if (string.IsNullOrEmpty(file.FieldName))
file.FieldName = "file" + nameIndex++;
part.Headers["Content-Disposition"] = "form-data; name=\"" + file.FieldName + "\"; filename=\"" + file.FileName + "\"";
part.Headers["Content-Type"] = file.ContentType;
part.SetStream(file.Data);
mimeParts.Add(part);
}
string boundary = "----------" + DateTime.Now.Ticks.ToString("x");
req.ContentType = "multipart/form-data; boundary=" + boundary;
req.Method = "POST";
long contentLength = 0;
byte[] _footer = Encoding.UTF8.GetBytes("--" + boundary + "--\r\n");
foreach (MimePart part in mimeParts)
{
contentLength += part.GenerateHeaderFooterData(boundary);
}
req.ContentLength = contentLength + _footer.Length;
byte[] buffer = new byte[8192];
byte[] afterFile = Encoding.UTF8.GetBytes("\r\n");
int read;
using (Stream s = req.GetRequestStream())
{
foreach (MimePart part in mimeParts)
{
s.Write(part.Header, 0, part.Header.Length);
while ((read = part.Data.Read(buffer, 0, buffer.Length)) > 0)
s.Write(buffer, 0, read);
part.Data.Dispose();
s.Write(afterFile, 0, afterFile.Length);
}
s.Write(_footer, 0, _footer.Length);
}
return (HttpWebResponse)req.GetResponse();
}
catch
{
foreach (MimePart part in mimeParts)
if (part.Data != null)
part.Data.Dispose();
throw;
}
And there is example of using :
UploadFile[] files = new UploadFile[]
{
new UploadFile(@"C:\2.jpg","new_file","image/jpeg") //new_file is id of upload field
};
NameValueCollection form = new NameValueCollection();
form["id_hidden_input"] = "value_hidden_inpu"; //there is additional param (hidden fields on page)
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(full URL of action);
// set credentials/cookies etc.
req.CookieContainer = hrm.CookieContainer; //hrm is my class. i copied all cookies from last request to current (for auth)
HttpWebResponse resp = HttpUploadHelper.Upload(req, files, form);
using (Stream s = resp.GetResponseStream())
using (StreamReader sr = new StreamReader(s))
{
string response = sr.ReadToEnd();
}
//profit!

ReactJs defines the following synthetic events for mouse events:
onClick onContextMenu onDoubleClick onDrag onDragEnd onDragEnter onDragExit
onDragLeave onDragOver onDragStart onDrop onMouseDown onMouseEnter onMouseLeave
onMouseMove onMouseOut onMouseOver onMouseUp
As you can see there is no hover event, because browsers do not define a hover event natively.
You will want to add handlers for onMouseEnter and onMouseLeave for hover behavior.
SO thread 'Multiply two arrays element wise, where one of the arrays has arrays as elements' has an example of constructing an array from arrays. If the subarrays are the same size, numpy makes a 2d array. But if they differ in length, it makes an array with dtype=object
, and the subarrays retain their identity.
Following that, you could do something like this:
In [5]: result=np.array([np.zeros((1)),np.zeros((2))])
In [6]: result
Out[6]: array([array([ 0.]), array([ 0., 0.])], dtype=object)
In [7]: np.append([result[0]],[1,2])
Out[7]: array([ 0., 1., 2.])
In [8]: result[0]
Out[8]: array([ 0.])
In [9]: result[0]=np.append([result[0]],[1,2])
In [10]: result
Out[10]: array([array([ 0., 1., 2.]), array([ 0., 0.])], dtype=object)
However, I don't offhand see what advantages this has over a pure Python list or lists. It does not work like a 2d array. For example I have to use result[0][1]
, not result[0,1]
. If the subarrays are all the same length, I have to use np.array(result.tolist())
to produce a 2d array.

The problem is in the ()
you have to go []
if (isset($_POST('sms_code') == TRUE)
by
if (isset($_POST['sms_code'] == TRUE)
You could make use of Prepared Stements
like this.

Don't forget that, even though tabindex
is all lowercase in the specs and in the HTML, in Javascript/the DOM that property is called tabIndex
.
Don't lose your mind trying to figure out why your programmatically altered tab indices calling element.tabindex = -1
isn't working. Use element.tabIndex = -1
.
Add an onclick
to your DIV
tag.
It already exists with find only not in that exact syntax.
if (m.find(2) == m.end() )
{
// key 2 doesn't exist
}
If you want to access the value if it exists, you can do:
map<int, Bar>::iterator iter = m.find(2);
if (iter != m.end() )
{
// key 2 exists, do something with iter->second (the value)
}
With C++0x and auto, the syntax is simpler:
auto iter = m.find(2);
if (iter != m.end() )
{
// key 2 exists, do something with iter->second (the value)
}
I recommend you get used to it rather than trying to come up with a new mechanism to simplify it. You might be able to cut down a little bit of code, but consider the cost of doing that. Now you've introduced a new function that people familiar with C++ won't be able to recognize.
If you want to implement this anyway in spite of these warnings, then:
template <class Key, class Value, class Comparator, class Alloc>
bool getValue(const std::map<Key, Value, Comparator, Alloc>& my_map, int key, Value& out)
{
typename std::map<Key, Value, Comparator, Alloc>::const_iterator it = my_map.find(key);
if (it != my_map.end() )
{
out = it->second;
return true;
}
return false;
}

If you're interested in learning a language which supports massive parallelism better go for OpenCL since you don't have an NVIDIA GPU. You can run OpenCL on Intel CPUs, but at best you can learn to program SIMDs. Optimization on CPU and GPU are different. I really don't think you can use Intel card for GPGPU.
Use Flexbox:
.outerDiv {
display: flex;
flex-direction: column;
justify-content: center; /* Centering y-axis */
align-items :center; /* Centering x-axis */

I am using this code for my project
$(window).scroll ( function() {

Probably this will help
First off, (though this won't change the performance at all) consider cleaning up your code, similar to this:
import matplotlib.pyplot as plt
import numpy as np
import time
x = np.arange(0, 2*np.pi, 0.01)
y = np.sin(x)
fig, axes = plt.subplots(nrows=6)
styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
lines = [ax.plot(x, y, style)[0] for ax, style in zip(axes, styles)]
fig.show()
tstart = time.time()
for i in xrange(1, 20):
for j, line in enumerate(lines, start=1):
line.set_ydata(np.sin(j*x + i/10.0))
fig.canvas.draw()
print 'FPS:' , 20/(time.time()-tstart)
With the above example, I get around 10fps.
Just a quick note, depending on your exact use case, matplotlib may not be a great choice. It's oriented towards publication-quality figures, not real-time display.
However, there are a lot of things you can do to speed this example up.
There are two main reasons why this is as slow as it is.
1) Calling fig.canvas.draw()
redraws everything. It's your bottleneck. In your case, you don't need to re-draw things like the axes boundaries, tick labels, etc.
2) In your case, there are a lot of subplots with a lot of tick labels. These take a long time to draw.
Both these can be fixed by using blitting.
To do blitting efficiently, you'll have to use backend-specific code. In practice, if you're really worried about smooth animations, you're usually embedding matplotlib plots in some sort of gui toolkit, anyway, so this isn't much of an issue.
However, without knowing a bit more about what you're doing, I can't help you there.
Nonetheless, there is a gui-neutral way of doing it that is still reasonably fast.
import matplotlib.pyplot as plt
import numpy as np
import time
x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)
fig, axes = plt.subplots(nrows=6)
fig.show()
# We need to draw the canvas before we start animating...
fig.canvas.draw()
styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
def plot(ax, style):
return ax.plot(x, y, style, animated=True)[0]
lines = [plot(ax, style) for ax, style in zip(axes, styles)]
# Let's capture the background of the figure
backgrounds = [fig.canvas.copy_from_bbox(ax.bbox) for ax in axes]
tstart = time.time()
for i in xrange(1, 2000):
items = enumerate(zip(lines, axes, backgrounds), start=1)
for j, (line, ax, background) in items:
fig.canvas.restore_region(background)
line.set_ydata(np.sin(j*x + i/10.0))
ax.draw_artist(line)
fig.canvas.blit(ax.bbox)
print 'FPS:' , 2000/(time.time()-tstart)
This gives me ~200fps.
To make this a bit more convenient, there's an animations
module in recent versions of matplotlib.
As an example:
import matplotlib.pyplot as plt
import matplotlib.animation as animation
import numpy as np
x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)
fig, axes = plt.subplots(nrows=6)
styles = ['r-', 'g-', 'y-', 'm-', 'k-', 'c-']
def plot(ax, style):
return ax.plot(x, y, style, animated=True)[0]
lines = [plot(ax, style) for ax, style in zip(axes, styles)]
def animate(i):
for j, line in enumerate(lines, start=1):
line.set_ydata(np.sin(j*x + i/10.0))
return lines
# We'd normally specify a reasonable "interval" here...
ani = animation.FuncAnimation(fig, animate, xrange(1, 200),
interval=0, blit=True)
plt.show()
If anyone is running into the default value occasionally being not populated on the page in Chrome, IE 10/11, Firefox -- try adding this attribute to your input/select field checking for the populated variable in the HTML, like so:
<input data-ng-model="vm.x" data-ng-if="vm.x !== '' && vm.x !== undefined && vm.x !== null" />
The way I have done this is by using my own class loader
URLClassLoader urlClassLoader = (URLClassLoader) ClassLoader.getSystemClassLoader();
DynamicURLClassLoader dynalLoader = new DynamicURLClassLoader(urlClassLoader);
And create the following class:
public class DynamicURLClassLoader extends URLClassLoader {
public DynamicURLClassLoader(URLClassLoader classLoader) {
super(classLoader.getURLs());
}
@Override
public void addURL(URL url) {
super.addURL(url);
}
}
Works without any reflection

If you are using Eclipse, then you can setup your JDK (not JRE) in Installed JREs, and then use Open Type (Ctrl + Shift + T), give something like java.util.Collections
Here is the VB.Net rendition of Rachel's answer above.
Obviously the XAML binding is the same...
<Button Command="{Binding Path=SaveCommand}" />
Your Custom Class would look like this...
''' <summary>
''' Retrieves an new or existing RelayCommand.
''' </summary>
''' <returns>[RelayCommand]</returns>
Public ReadOnly Property SaveCommand() As ICommand
Get
If _saveCommand Is Nothing Then
_saveCommand = New RelayCommand(Function(param) SaveObject(), Function(param) CanSave())
End If
Return _saveCommand
End Get
End Property
Private _saveCommand As ICommand
''' <summary>
''' Returns Boolean flag indicating if command can be executed.
''' </summary>
''' <returns>[Boolean]</returns>
Private Function CanSave() As Boolean
' Verify command can be executed here.
Return True
End Function
''' <summary>
''' Code to be run when the command is executed.
''' </summary>
''' <remarks>Converted to a Function in VB.net to avoid the "Expression does not produce a value" error.</remarks>
''' <returns>[Nothing]</returns>
Private Function SaveObject()
' Save command execution logic.
Return Nothing
End Function
And finally the RelayCommand class is as follows...
Public Class RelayCommand : Implements ICommand
ReadOnly _execute As Action(Of Object)
ReadOnly _canExecute As Predicate(Of Object)
Private Event ICommand_CanExecuteChanged As EventHandler Implements ICommand.CanExecuteChanged
''' <summary>
''' Creates a new command that can always execute.

Public Sub New(execute As Action(Of Object), canExecute As Predicate(Of Object))
If execute Is Nothing Then
Throw New ArgumentNullException("execute")
End If
_execute = execute
_canExecute = canExecute
End Sub
<DebuggerStepThrough>
Public Function CanExecute(parameters As Object) As Boolean Implements ICommand.CanExecute
Return If(_canExecute Is Nothing, True, _canExecute(parameters))
End Function
Public Custom Event CanExecuteChanged As EventHandler

End Class
Hope that helps any VB.Net developers!
Probably you instance old fragment it is keeping a reference. See this interesting article Memory leaks in Android — identify, treat and avoid
If you use addToBackStack, this keeps a reference to instance fragment avoiding to Garbage Collector erase the instance. The instance remains in fragments list in fragment manager. You can see the list by
ArrayList<Fragment> fragmentList = fragmentManager.getFragments();
The next code is not the best solution (because don´t remove the old fragment instance in order to avoid memory leaks) but removes the old fragment from fragmentManger fragment list
int index = fragmentManager.getFragments().indexOf(oldFragment);
fragmentManager.getFragments().set(index, null);
You cannot remove the entry in the arrayList because apparenly FragmentManager works with index ArrayList to get fragment.
I usually use this code for working with fragmentManager
public void replaceFragment(Fragment fragment, Bundle bundle) {
if (bundle != null)
fragment.setArguments(bundle);
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
Fragment oldFragment = fragmentManager.findFragmentByTag(fragment.getClass().getName());
//if oldFragment already exits in fragmentManager use it
if (oldFragment != null) {
fragment = oldFragment;
}
fragmentTransaction.replace(R.id.frame_content_main, fragment, fragment.getClass().getName());
fragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
fragmentTransaction.commit();
}
I encountered a similar error with RubyMine 2016.3 recently, wherein any attempts at checkout or export to Github were met with "Cannot run program 'C:\Program Files (x86)\Git\cmd\git.exe': CreateProcess error=2, The system cannot find the file specified"
As an alternative solution for this problem, other than editing the Path system variable, you can try searching through the program files of Android Studio for a git.xml file and editing the myPathToGit option to match the actual location of git.exe on your computer. This is how I fixed this similar issue in RubyMine.
Posting this solution here for the sake of posterity.
Excellent answer from above turned into a simple utility method.
private Uri buildURI(String url, Map<String, String> params) {
// build url with parameters.
Uri.Builder builder = Uri.parse(url).buildUpon();
for (Map.Entry<String, String> entry : params.entrySet()) {
builder.appendQueryParameter(entry.getKey(), entry.getValue());
}
return builder.build();
}
have you tried this?
-
name: Jack
age: 32
-
name: Claudia
age: 25
I get this: [{"name"=>"Jack", "age"=>32}, {"name"=>"Claudia", "age"=>25}]
(I use the YAML
Ruby class).
It depends on the jQuery selector that you use. Since id
should be unique within the DOM, the first one would be simple:
$('#Comanda').hide();
The second one might require something more, depending on the other elements and how to uniquely identify it. If the name
of that particular input
is unique, then this would work:
$('input[name="Vizualizeaza"]').hide();
player['score']
is your problem. player is apparently a list
which means that there is no 'score' element. Instead you would do something like:
name, score = player[0], player[1]
return name + ' ' + str(score)
Of course, you would have to know the list indices (those are the 0 and 1 in my example).
Something like player['score']
is allowed in python, but player
would have to be a dict
.
You can read more about both lists and dicts in the python documentation.
Don't know if you solved the problem but if anyone has this problem in future.
$python
>>import numpy
>>print(numpy)
Go to the location printed and delete the numpy
installation found there. You can then use pip
or easy_install
Here is a jQuery plugin that will handle everything for you, Transify (Transify - a jQuery plugin to easily apply transparency / opacity to an element’s background).
I was running into this problem every now and then, so I decided to write something that would make life a lot easier. The script is less than 2 KB and it only requires one line of code to get it to work, and it will also handle animating the opacity of the background if you like.
All you have to do is open Anaconda Prompt and type
pip install package-name
It will automatically install to the anaconda environment without having to use
conda install package-name
Since some of the conda packages may lack support overtime it is required to install using pip and this is one way to do it
If you have pip installed in anaconda you can run the following in jupyter notebook or in your python shell that is linked to anaconda
pip.main(['install', 'package-name'])
Check your version of pip with pip.__version__
. If it is version 10.x.x
or above, then install your python package with this line of code
subprocess.check_call([sys.executable, '-m', 'pip', 'install', '--upgrade', 'package-name'])
In your jupyter notebook, you can install python packages through pip in a cell this way;
!pip install package-name
or you could use your python version associated with anaconda
!python3.6 -m pip install package-name
$sidemenu
is not an object
, so you can't call methods on it. It is probably not being sent to your view
, or $sidemenus
is empty.
Though a bit late, there is :/
which is the dedicated notation to specify a commit (or revision) based on the commit message, just prefix the search string with :/
, e.g.:
git show :/keyword(s)
Here <keywords>
can be a single word, or a complex regex pattern consisting of whitespaces, so please make sure to quote/escape when necessary, e.g.:
git log -1 -p ":/a few words"
Alternatively, a start point can be specified, to find the closest commit reachable from a specific point, e.g.:
git show 'HEAD^{/fix nasty bug}'
See: git revisions manual.
Because you did not write a comparison operator for your struct. The compiler does not generate it for you, so if you want comparison, you have to write it yourself.
let str = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
let regexp = /[a-d]/gi;
console.log(str.match(regexp));
The syntax is wrong in this clause (and similar ones)
CASE lkey WHEN lkey > 5 THEN
lkey + 2
ELSE
lkey
END
It's either
CASE WHEN [condition] THEN [expression] ELSE [expression] END
or
CASE [expression] WHEN [value] THEN [expression] ELSE [expression] END
So in your case it would read:
CASE WHEN lkey > 5 THEN
lkey + 2
ELSE
lkey
END
Check out the documentation (The CASE expression):
netsh wlan set hostednetwork mode=allow ssid=dhiraj key=7870049877
Have a look at the ReadAsset.java from API samples that come with the SDK.
try {
InputStream is = getAssets().open("read_asset.txt");
// We guarantee that the available method returns the total
// size of the asset... of course, this does mean that a single
// asset can't be more than 2 gigs.
int size = is.available();
// Read the entire asset into a local byte buffer.
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
// Convert the buffer into a string.
String text = new String(buffer);
// Finally stick the string into the text view.
TextView tv = (TextView)findViewById(R.id.text);
tv.setText(text);
} catch (IOException e) {
// Should never happen!
throw new RuntimeException(e);
}
Since they are already inline-block
child elements, you can set text-align:center
on the parent without having to set a width
or margin:0px auto
on the child. Meaning it will work for dynamically generated content with varying widths
.
.img_container, .img_container2 {
text-align: center;
}
This will center the child within both div
containers.
UPDATE:
For vertical centering, you can use the calc()
function assuming the height of the icon is known.
.img_container > i, .img_container2 > i {
position:relative;
top: calc(50% - 10px); /* 50% - 3/4 of icon height */
}
jsFiddle demo - it works.
For what it's worth - you can also use vertical-align:middle
assuming display:table-cell
is set on the parent.
Docker Compose does not support the deploy
key. It's only respected when you use your version 3 YAML file in a Docker Stack.
This message is printed when you add the deploy
key to you docker-compose.yml
file and then run docker-compose up -d
WARNING: Some services (database) use the 'deploy' key, which will be ignored. Compose does not support 'deploy' configuration - use
docker stack deploy
to deploy to a swarm.
The documentation (https://docs.docker.com/compose/compose-file/#deploy) says:
Specify configuration related to the deployment and running of services. This only takes effect when deploying to a swarm with docker stack deploy, and is ignored by docker-compose up and docker-compose run.
Gradle looks for gradle.properties
files in these places:
GRADLE_USER_HOME
environment variable, which if not set defaults to USER_HOME/.gradle
)Properties from one file will override the properties from the previous ones (so file in gradle user home has precedence over the others, and file in sub-project has precedence over the one in project root).

Simply using sort, use coloumn number based on which you want to sort.
a = np.array([1,1], [1,-1], [-1,1], [-1,-1]])
print (a)
a=a.tolist()
a = np.array(sorted(a, key=lambda a_entry: a_entry[0]))
print (a)
To get cell column name as well as cell value :
List<JObject> dataList = new List<JObject>();
for (int i = 0; i < dataTable.Rows.Count; i++)
{
JObject eachRowObj = new JObject();
for (int j = 0; j < dataTable.Columns.Count; j++)
{
string key = Convert.ToString(dataTable.Columns[j]);
string value = Convert.ToString(dataTable.Rows[i].ItemArray[j]);
eachRowObj.Add(key, value);
}
dataList.Add(eachRowObj);
}
I guess the someList.ForEach()
call could be easily parallelized whereas the normal foreach
is not that easy to run parallel.
You could easily run several different delegates on different cores, which is not that easy to do with a normal foreach
.
Just my 2 cents
Instead of typedef struct { ... } pos;
you should be doing struct pos { ... };
. The issue here is that you are using the pos
type name before it is defined. By moving the name to the top of the struct definition, you are able to use that name within the struct definition itself.
Further, the typedef struct { ... } name;
pattern is a C-ism, and doesn't have much place in C++.
To answer your question about inline
, there is no difference in this case. When a method is defined within the struct/class definition, it is implicitly declared inline. When you explicitly specify inline
, the compiler effectively ignores it because the method is already declared inline.
(inline
methods will not trigger a linker error if the same method is defined in multiple object files; the linker will simply ignore all but one of them, assuming that they are all the same implementation. This is the only guaranteed change in behavior with inline methods. Nowadays, they do not affect the compiler's decision regarding whether or not to inline functions; they simply facilitate making the function implementation available in all translation units, which gives the compiler the option to inline the function, if it decides it would be beneficial to do so.)
You should try this, This technique is OS Independent.
In side your application there is a folder called tmp, inside that there is an another folder called pids. That file contains the server pid file. Simply delete that file. port automatically kill itself.
I think this is the easy way.
What directory is file.txt in? cron runs jobs in your home directory, so unless your script cd
s somewhere else, that's where it's going to look for/create file.txt.
EDIT: When you refer to a file without specifying its full path (e.g. file.txt
, as opposed to the full path /home/myUser/scripts/file.txt
) in shell, it's taken that you're referring to a file in your current working directory. When you run a script (whether interactively or via crontab), the script's working directory has nothing at all to do with the location of the script itself; instead, it's inherited from whatever ran the script.
Thus, if you cd
(change working directory) to the directory the script's in and then run it, file.txt
will refer to a file in the same directory as the script. But if you don't cd
there first, file.txt
will refer to a file in whatever directory you happen to be in when you ran the script. For instance, if your home directory is /home/myUser, and you open a new shell and immediately run the script (as scripts/test.sh
or /home/myUser/scripts/test.sh
; ./test.sh
won't work), it'll touch the file /home/myUser/file.txt because /home/myUser is your current working directory (and therefore the script's).
When you run a script from cron
, it does essentially the same thing: it runs it with the working directory set to your home directory. Thus all file references in the script are taken relative to your home directory, unless the script cd
s somewhere else or specifies an absolute path to the file.

Based on the hint and link provided in Simone Giannis answer, this is my hack to fix this.
I am testing on uri.getAuthority(), because UNC path will report an Authority. This is a bug - so I rely on the existence of a bug, which is evil, but it apears as if this will stay forever (since Java 7 solves the problem in java.nio.Paths).
Note: In my context I will receive absolute paths. I have tested this on Windows and OS X.
(Still looking for a better way to do it)

You need to tell the Range.RemoveDuplicates method what column to use. Additionally, since you have expressed that you have a header row, you should tell the .RemoveDuplicates method that.
Sub dedupe_abcd()
Dim icol As Long
With Sheets("Sheet1") '<-set this worksheet reference properly!
icol = Application.Match("abcd", .Rows(1), 0)
With .Cells(1, 1).CurrentRegion
.RemoveDuplicates Columns:=icol, Header:=xlYes
End With
End With
End Sub
Your original code seemed to want to remove duplicates from a single column while ignoring surrounding data. That scenario is atypical and I've included the surrounding data so that the .RemoveDuplicates process does not scramble your data. Post back a comment if you truly wanted to isolate the RemoveDuplicates process to a single column.
Give your button an id something like this:
<input id="mybutton" type="button" value="Dont show this again! " />
Then use jquery (to make this unobtrusive) and attach click action like so:
$(document).ready(function (){
$('#mybutton').click(function (){
fbLikeDump();
WriteCookie();
});
});
(this part should be in your .js file too)
I should have mentioned that you will need the jquery libraries on your page, so right before your closing body tag add these:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript" src="http://PATHTOYOURJSFILE"></script>
The reason to add just before body closing tag is for performance of perceived page loading times
If you are on xampp and using phpMyadmin to import large sql files and you have increased max_execution time, max file upload limit and everything needed And If none of the above answers work for you come here

If you are using multiple flavors?
-make sure the resource file is not declared/added both in only one of the flavors and in main.
Example: a_layout_file.xml
file containing the symbol variable(s)
src:
flavor1/res/layout/(no file)
flavor2/res/layout/a_layout_file.xml
main/res/layout/a_layout_file.xml
This setup will give the error: cannot find symbol variable, this is because the resource file can only be in both flavors or only in the main.
If you are still getting that error after installing the 64 bit JRE, it means that the JVM running Gurobi package is still using the 32 bit JRE.
Check that you have updated the PATH and JAVA_HOME globally and in the command shell that you are using. (Maybe you just need to exit and restart it.)
Check that your command shell runs the right version of Java by running "java -version" and checking that it says it is a 64bit JRE.
If you are launching the example via a wrapper script / batch file, make sure that the script is using the right JRE. Modify as required ...
$.post("test.php", { 'choices[]': ["Jon", "Susan"] });
So I would just iterate over the checked boxes and build the array. Something like.
var data = { 'user_ids[]' : []};
$(":checked").each(function() {
data['user_ids[]'].push($(this).val());
});
$.post("ajax.php", data);
There is one more difference of using the app and listening to http server is when you want to setup for https server
To setup for https, you need the code below:
var https = require('https');
var server = https.createServer(app).listen(config.port, function() {
console.log('Https App started');
});
The app from express will return http server only, you cannot set it in express, so you will need to use the https server command
var express = require('express');
var app = express();
app.listen(1234);
Sometimes we want to catch a SIGSEGV
to find out if a pointer is valid, that is, if it references a valid memory address. (Or even check if some arbitrary value may be a pointer.)
One option is to check it with isValidPtr()
(worked on Android):
int isValidPtr(const void*p, int len) {
if (!p) {
return 0;
}
int ret = 1;
int nullfd = open("/dev/random", O_WRONLY);
if (write(nullfd, p, len) < 0) {
ret = 0;
/* Not OK */
}
close(nullfd);
return ret;
}
int isValidOrNullPtr(const void*p, int len) {
return !p||isValidPtr(p, len);
}
Another option is to read the memory protection attributes, which is a bit more tricky (worked on Android):
re_mprot.c:
#include <errno.h>
#include <malloc.h>
//#define PAGE_SIZE 4096
#include "dlog.h"
#include "stdlib.h"
#include "re_mprot.h"

is defined here.
PPS It may not be a good idea to call alloca() in a loop -- the memory may be not freed until the function returns.
Most other solutions here require that you create the table in advance/manually. This may not be practical in some cases (e.g., if you have a lot of columns in the destination table). So, the approach below may come handy.
Providing the path and column count of your csv file, you can use the following function to load your table to a temp table that will be named as target_table
:
The top row is assumed to have the column names.
create or replace function data.load_csv_file
(
target_table text,
csv_path text,
col_count integer
)
returns void as $$
declare
iter integer; -- dummy integer to iterate columns with
col text; -- variable to keep the column name at each iteration
col_first text; -- first column name, e.g., top left corner on a csv file or spreadsheet
begin
create table temp_table ();
-- add just enough number of columns
for iter in 1..col_count
loop
execute format('alter table temp_table add column col_%s text;', iter);
end loop;
-- copy the data from csv file
execute format('copy temp_table from %L with delimiter '','' quote ''"'' csv ', csv_path);
iter := 1;
col_first := (select col_1 from temp_table limit 1);
-- update the column names based on the first row which has the column names
for col in execute format('select unnest(string_to_array(trim(temp_table::text, ''()''), '','')) from temp_table where col_1 = %L', col_first)
loop
execute format('alter table temp_table rename column col_%s to %s', iter, col);
iter := iter + 1;
end loop;
-- delete the columns row
execute format('delete from temp_table where %s = %L', col_first, col_first);
-- change the temp table name to the name given as parameter, if not blank
if length(target_table) > 0 then
execute format('alter table temp_table rename to %I', target_table);
end if;
end;

That worked for me to import 400MB file into my database.
None of these solutions worked for what I needed which was a ScrollView set to wrap_content but having a maxHeight so it would stop expanding after a certain point and start scrolling. I just simply overrode the onMeasure method in ScrollView.
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
heightMeasureSpec = MeasureSpec.makeMeasureSpec(300, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
This might not work in all situations, but it certainly gives me the results needed for my layout. And it also addresses the comment by madhu.
If some layout present below the scrollview then this trick wont work – madhu Mar 5 at 4:36
Since I spent quite some time trying to solve this and always came back to this page when looking for this error, I'll leave my solution here hoping that somebody saves the time I've lost. Although in my case I am using mariadb rather than MySql, you might still be able to adapt this solution to your needs.
is the same, but my setup is a bit different (mariadb instead of mysql):
Installed mariadb with homebrew
$ brew install mariadb
Started the daemon
$ brew services start mariadb
Tried to connect and got the above mentioned error
$ mysql -uroot
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
find out which my.cnf
files are used by mysql
(as suggested in this comment):
$ mysql --verbose --help | grep my.cnf
/usr/local/etc/my.cnf ~/.my.cnf
order of preference, my.cnf, $MYSQL_TCP_PORT,
check where the Unix socket file is running (almost as described here):
$ netstat -ln | grep mariadb
.... /usr/local/mariadb/data/mariadb.sock
(you might want to grep mysql
instead of mariadb)
Add the socket file you found to ~/.my.cnf
(create the file if necessary)(assuming ~/.my.cnf
was listed when running the mysql --verbose ...
-command from above):
[client]
socket = /usr/local/mariadb/data/mariadb.sock
Restart your mariadb:
$ brew services restart mariadb
After this I could run mysql and got:
$ mysql -uroot
ERROR 1698 (28000): Access denied for user 'root'@'localhost'
So I run the command with superuser privileges instead and after entering my password I got:
$ sudo mysql -uroot
MariaDB [(none)]>
Notes:
I'm not quite sure about the groups where you have to add the socket, first I had it [client-server] but then I figured [client] should be enough. So I changed it and it still works.
When running mariadb_config | grep socket
I get:
--socket [/tmp/mysql.sock]
which is a bit confusing since it seems that /usr/local/mariadb/data/mariadb.sock
is the actual place (at least on my machine)
I wonder where I can configure the /usr/local/mariadb/data/mariadb.sock
to actually be /tmp/mysql.sock
so I can use the default settings instead of having to edit my .my.cnf
(but I'm too tired now to figure that out...)
At some point I also did things mentioned in other answers before coming up with this.
