Using the code example below will return to you the bitmap :

BitmapFactory.decodeStream(getContentResolver().openInputStream(Uri.parse("content://com.whatsapp.provider.media/item/128752")))

After that you all know what you have to do.

This error occurs me when I use path.resolve(), to set up 'entry' and 'output' settings. entry: path.resolve(__dirname + '/app.jsx'). Just try entry: __dirname + '/app.jsx'

I don't have enough reputation to comment but I want to add, that the cp number of the .whl file stands for your python version.

cp35 -> Python 3.5.x

cp36 -> Python 3.6.x

cp37 -> Python 3.7.x

I think it's pretty obvious but still I wasted almost an hour because of this and maybe other people struggle with that, too.

So for me worked version cp36 that I downloaded here: https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy since I am using Python 3.6.8.

Then I uninstalled numpy:

pip uninstall numpy 

Then I installed numpy+mkl:

pip install <destination of your .whl file>

You are likely running the Mac default (/usr/bin/python) which has an older version of numpy installed in the system folders. The easiest way to get python working with opencv is to use brew to install both python and opencv into /usr/local and run the /usr/local/bin/python.

brew install python
brew tap homebrew/science
brew install opencv

This is an edge case, but you can also get this error if you are building an MFC application with CMake.

In that case, you need to add the following definitions:

ADD_DEFINITIONS(-D_AFXDLL) SET(CMAKE_MFC_FLAG 2) # or 1 if you are looking for the static library

If you are compiling with unicode, the following properties also need to be added:

set_target_properties(MyApp PROPERTIES COMPILE_DEFINITIONS _AFXDLL,_UNICODE,UNICODE,_BIND_TO_CURRENT_CRT_VERSION,_BIND_TO_CURRENT_MFC_VERSION LINK_FLAGS "/ENTRY:\"wWinMainCRTStartup\"" )

Android Documentation on Manifest.permission.Manifest.permission.WRITE_EXTERNAL_STORAGE states:

Starting in API level 19, this permission is not required to read/write files in your application-specific directories returned by getExternalFilesDir(String) and getExternalCacheDir().

I think that this means you do not have to code for the run-time implementation of the WRITE_EXTERNAL_STORAGE permission unless the app is writing to a directory that is not specific to your app.

You can define the max sdk version in the manifest per permission like:

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="19" />

Also make sure to change the target SDK in the build.graddle and not the manifest, the gradle settings will always overwrite the manifest settings.

android {
compileSdkVersion 23
buildToolsVersion '23.0.1'
defaultConfig {
    minSdkVersion 17
    targetSdkVersion 22
}

If you are using a simulator in Android Studio on Mac you can go to View -> Tool Windows -> Device File Explorer. Here you can use a finder-like structure.

For those who are getting Error Unknown URI: content://downloads/public_downloads. I managed to solve this by getting a hint given by @Commonsware in this answer. I found out the class FileUtils on GitHub. Here InputStream methods are used to fetch file from Download directory.

 // DownloadsProvider
            else if (isDownloadsDocument(uri)) {

                final String id = DocumentsContract.getDocumentId(uri);

                if (id != null && id.startsWith("raw:")) {
                    return id.substring(4);
                }

                String[] contentUriPrefixesToTry = new String[]{
                        "content://downloads/public_downloads",
                        "content://downloads/my_downloads",
                        "content://downloads/all_downloads"
                };

                for (String contentUriPrefix : contentUriPrefixesToTry) {
                    Uri contentUri = ContentUris.withAppendedId(Uri.parse(contentUriPrefix), Long.valueOf(id));
                    try {
                        String path = getDataColumn(context, contentUri, null, null);
                        if (path != null) {
                            return path;
                        }
                    } catch (Exception e) {}
                }

                // path could not be retrieved using ContentResolver, therefore copy file to accessible cache using streams
                String fileName = getFileName(context, uri);
                File cacheDir = getDocumentCacheDir(context);
                File file = generateFileName(fileName, cacheDir);
                String destinationPath = null;
                if (file != null) {
                    destinationPath = file.getAbsolutePath();
                    saveFileFromUri(context, uri, destinationPath);
                }

                return destinationPath;
            }

Microsoft has a special note on this (https://msdn.microsoft.com/en-us/library/bb531344.aspx#BK_CRT):

The printf and scanf family of functions are now defined inline.

The definitions of all of the printf and scanf functions have been moved inline into stdio.h, conio.h, and other CRT headers. This is a breaking change that leads to a linker error (LNK2019, unresolved external symbol) for any programs that declared these functions locally without including the appropriate CRT headers. If possible, you should update the code to include the CRT headers (that is, add #include ) and the inline functions, but if you do not want to modify your code to include these header files, an alternative solution is to add an additional library to your linker input, legacy_stdio_definitions.lib.

To add this library to your linker input in the IDE, open the context menu for the project node, choose Properties, then in the Project Properties dialog box, choose Linker, and edit the Linker Input to add legacy_stdio_definitions.lib to the semi-colon-separated list.

If your project links with static libraries that were compiled with a release of Visual C++ earlier than 2015, the linker might report an unresolved external symbol. These errors might reference internal stdio definitions for _iob, _iob_func, or related imports for certain stdio functions in the form of __imp_*. Microsoft recommends that you recompile all static libraries with the latest version of the Visual C++ compiler and libraries when you upgrade a project. If the library is a third-party library for which source is not available, you should either request an updated binary from the third party or encapsulate your usage of that library into a separate DLL that you compile with the older version of the Visual C++ compiler and libraries.

I am not sure if I fully understand your problem but since I had similar issue recently I will try to help you out.

Vendor bundle.

You should use CommonsChunkPlugin for that. in the configuration you specify the name of the chunk (e.g. vendor), and file name that will be generated (vendor.js).

new webpack.optimize.CommonsChunkPlugin("vendor", "vendor.js", Infinity),

Now important part, you have to now specify what does it mean vendor library and you do that in an entry section. One one more item to entry list with the same name as the name of the newly declared chunk (i.e. 'vendor' in this case). The value of that entry should be the list of all the modules that you want to move to vendor bundle. in your case it should look something like:

entry: {
    app: 'entry.js',
    vendor: ['jquery', 'jquery.plugin1']
}

JQuery as global

Had the same problem and solved it with ProvidePlugin. here you are not defining global object but kind of shurtcuts to modules. i.e. you can configure it like that:

new webpack.ProvidePlugin({
    $: "jquery"
})

And now you can just use $ anywhere in your code - webpack will automatically convert that to

require('jquery')

I hope it helped. you can also look at my webpack configuration file that is here

I love webpack, but I agree that the documentation is not the nicest one in the world... but hey.. people were saying same thing about Angular documentation in the begining :)

Edit:

To have entrypoint-specific vendor chunks just use CommonsChunkPlugins multiple times:

new webpack.optimize.CommonsChunkPlugin("vendor-page1", "vendor-page1.js", Infinity),
new webpack.optimize.CommonsChunkPlugin("vendor-page2", "vendor-page2.js", Infinity),

and then declare different extenral libraries for different files:

entry: {
    page1: ['entry.js'],
    page2: ['entry2.js'],
    "vendor-page1": [
        'lodash'
    ],
    "vendor-page2": [
        'jquery'
    ]
},

If some libraries are overlapping (and for most of them) between entry points then you can extract them to common file using same plugin just with different configuration. See this example.

In my case I had to go to

File -> Settings -> Build, Execution, Deployment -> Gradle

and then I changed the Service directory path, which was pointing to a wrong location.

Hey I had the same issue.
You can find all the packages in the link below:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#scikit-learn
And choose the package you need for your version of windows and python.

You have to download the file with whl extension. After that, you will copy the file into your python directory then run the following command:
py -3.6 -m pip install matplotlib-2.1.0-cp36-cp36m-win_amd64.whl

Here is an example when I wanted to install matplolib for my python 3.6 https://www.youtube.com/watch?v=MzV4N4XUvYc
and this is the video I followed.

I have just tried that if you use SoapUI (5.4.x) and use Apache CXF tool to generate java code, put javax.xml.accessExternalSchema = all in YOUR_JDK/jre/lib/jaxp.properties file also works.

For me it was tls12:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

I want to open external storage directory path for saving file programatically.I tried but not getting sdcard path. How can i do this?is there any solution for this??

To store your app files in SD card, you should use File[] getExternalFilesDirs (String type) method in Context class. Generally, second returned path would be the storage path for microSD card (if any).

On my phone, second path returned was /storage/sdcard1/Android/data/your.application.package.appname/files after passing null as argument to getExternalFilesDirs (String type). But path may vary on different phones, different Android versions.

Both File getExternalStorageDirectory () and File getExternalStoragePublicDirectory (String type) in Environment class may return SD card directory or internal memory directory depending on your phone's model and Android OS version.

Because According to Official Android Guide external storage can be

removable storage media (such as an SD card) or an internal (non-removable) storage.

The Internal and External Storage terminology according to Google/official Android docs is quite different from what we think.

After reporting the problem on the Android Studio feedback site, they found a solution for me. I am now using Gradle 1.10 and Android Studio 0.4.3.

Here is the link to the page with a description of how I fixed mine: https://code.google.com/p/android/issues/detail?id=65219

Hope this helps!

Will something like this work for you? What this does is query the content resolver to find the file path data that is stored for that content entry

public static String getRealPathFromUri(Context context, Uri contentUri) {
    Cursor cursor = null;
    try {
        String[] proj = { MediaStore.Images.Media.DATA };
        cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(column_index);
    } finally {
        if (cursor != null) {
            cursor.close();
        }
    }
}

This will end up giving you an absolute file path that you can construct a file uri from

I have exactly the same issue. I ran a couple of virtual hosts on my local machine for developing.

First, I changed /etc/apache2/conf-available/php5-fpm.conf. I replaced every

Order Deny,Allow
Deny from all

to

Require all granted

The configuration has to be enabled by a2enconf php5-fpm. I did the same with my virtual hosts configurations and made the replacements.

I think this is not advised for security reasons, but as long as I use my server for local purposes only I can live with it.

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

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

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

As of API 24, sending a file:// URI to another app will throw a FileUriExposedException. Instead, use FileProvider to send a content:// URI:

public File getFile(Context context, String fileName) {
    if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
        return null;
    }

    File storageDir = context.getExternalFilesDir(null);
    return new File(storageDir, fileName);
}

public Uri getFileUri(Context context, String fileName) {
    File file = getFile(context, fileName);
    return FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", file);
}

You must also define the FileProvider in your manifest:

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="com.mydomain.fileprovider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />
</provider>

Example file_paths.xml:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-files-path name="name" path="path" />
</paths>

Replace "name" and "path" as appropriate.

To give the PDF viewer access to the file, you also have to add the FLAG_GRANT_READ_URI_PERMISSION flag to the intent:

private void displayPdf(String fileName) {
    Uri uri = getFileUri(this, fileName);

    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(uri, "application/pdf");

    // FLAG_GRANT_READ_URI_PERMISSION is needed on API 24+ so the activity opening the file can read it
    intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_GRANT_READ_URI_PERMISSION);

    if (intent.resolveActivity(getPackageManager()) == null) {
        // Show an error
    } else {
        startActivity(intent);
    }
}

See the FileProvider documentation for more details.

When you have everything #included, an unresolved external symbol is often a missing * or & in the declaration or definition of a function.

This works for me:

seekbarPlayer.setMax(mp.getDuration());
getActivity().runOnUiThread(new Runnable() {

    @Override
    public void run() {
        if(mp != null){
            seekbarPlayer.setProgress(mp.getCurrentPosition());
        }
        mHandler.postDelayed(this, 1000);
    }
});

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);

intent.setType("text/csv");

intent.addCategory(Intent.CATEGORY_OPENABLE);

try {
      startActivityForResult(Intent.createChooser(intent, "Select a File to Upload"), 0);

} catch (android.content.ActivityNotFoundException ex) {
  ex.printStackTrace();
}

then you just need to add the response

public void  onActivityResult(int requestCode, int resultCode, Intent data){

switch (requestCode) {
  case 0: {
     //what you want to do
    //file = new File(uri.getPath());
  }
}
}

Simple kotlin version

fun download(link: String, path: String) {
    URL(link).openStream().use { input ->
        FileOutputStream(File(path)).use { output ->
            input.copyTo(output)
        }
    }
}

EDIT

or as extension

fun String.saveTo(path: String) {
    URL(this).openStream().use { input ->
        FileOutputStream(File(path)).use { output ->
            input.copyTo(output)
        }
    }
}

// ...

"http://example.site/document".saveTo("some/path/file")

Today I was looking for this and Mr Brandon Rude gave an excellent answer. Unfortunately, AsyncTask is now depricated, you can still use it, but it gives you a warning which is very annoying. So an alternative is to use Executors like this way (in kotlin):

    val someRunnable = object : Runnable{
      override fun run() {
        // todo: do your background tasks
        requireActivity().runOnUiThread{
          // update views / ui if you are in a fragment
        };
        /*
        runOnUiThread {
          // update ui if you are in an activity
        }
        * */
      }
    };
    Executors.newSingleThreadExecutor().execute(someRunnable);

And in java it looks like this:

        Runnable someRunnable = new Runnable() {
            @Override
            public void run() {
                // todo: background tasks
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        // todo: update your ui / view in activity
                    }
                });

                /*
                requireActivity().runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        // todo: update your ui / view in Fragment
                    }
                });*/
            }
        };

        Executors.newSingleThreadExecutor().execute(someRunnable);

I did the following to get acces to all the external sd cards.

With:

File primaryExtSd=Environment.getExternalStorageDirectory();

you get the path to the primary external SD Then with:

File parentDir=new File(primaryExtSd.getParent());

you get the parent dir of the primary external storage, and it is also the parent of all the external sd. Now, you can list all the storage and select the one that you want.

Hope it is usefull.

You can run:

pip install pymorph

But you need to run that command in the anaconda terminal of your environment. For example:

List<String> list = Arrays.asList(array);

The list returned will be backed by the array, it acts like a bridge, so it will be fixed-size.

I just had a hard time with this. Everything was logically set up. I declared a constructor but didn't define it

class SomeClass
{
   SomeClass();  // needs the SomeClass::SomeClass(){} function defined somewhere, even here
}

I almost banged my head on my keyboard when I forgot something so elementary.

I have experienced the same issues as you described. It appears to be a bug on Tortoise 1.7.3. I have reverted back to 1.7.2, executed a cleanup and an update. Now my SVN/Tortoise is working fine again

The MediaStore API is probably throwing away the alpha channel (i.e. decoding to RGB565). If you have a file path, just use BitmapFactory directly, but tell it to use a format that preserves alpha:

BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap bitmap = BitmapFactory.decodeFile(photoPath, options);
selected_photo.setImageBitmap(bitmap);

or

http://mihaifonoage.blogspot.com/2009/09/displaying-images-from-sd-card-in.html

Try these

 String appDirectoryName = getResources().getString(R.string.app_name);
    File directory = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + getResources().getString(R.string.app_name));
    directory.mkdirs();
    File[] fList = directory.listFiles();
    int a = 1;
    for (int x = 0; x < fList.length; x++) {

        //txt.setText("You Have Capture " + String.valueOf(a) + " Photos");
        a++;
    }
    //get all the files from a directory
    for (File file : fList) {
        if (file.isFile()) {
            list.add(new ModelClass(file.getName(), file.getAbsolutePath()));
        }
    }

I've tried a lot of things to let this work on Marshmallow and Lollipop. Finally i ended up moving the saved picture to the DCIM folder (new Google Photo app scan images only if they are inside this folder apparently)

public static File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss")
         .format(System.currentTimeInMillis());
    File storageDir = new File(Environment
         .getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) + "/Camera/");
    if (!storageDir.exists())
        storageDir.mkdirs();
    File image = File.createTempFile(
            timeStamp,                   /* prefix */
            ".jpeg",                     /* suffix */
            storageDir                   /* directory */
    );
    return image;
}

And then the standard code for scanning files which you can find in the Google Developers site too.

public static void addPicToGallery(Context context, String photoPath) {
    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    File f = new File(photoPath);
    Uri contentUri = Uri.fromFile(f);
    mediaScanIntent.setData(contentUri);
    context.sendBroadcast(mediaScanIntent);
}

Please remember that this folder could not be present in every device in the world and that starting from Marshmallow (API 23), you need to request the permission to WRITE_EXTERNAL_STORAGE to the user.

For API level 23 (Marshmallow) and later, additional to uses-permission in manifest, pop up permission should also be implemented, and user needs to grant it while using the app in run-time.

Below, there is an example to save hello world! as content of myFile.txt file in Test directory inside picture directory.

In the manifest:

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

Where you want to create the file:

int permission = ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE);

String[] PERMISSIONS_STORAGE = {Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE};

if (permission != PackageManager.PERMISSION_GRANTED)
{
     ActivityCompat.requestPermissions(MainActivity.this,PERMISSIONS_STORAGE, 1);
}

File myDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "Test");

myDir.mkdirs();

try 
{
    String FILENAME = "myFile.txt";
    File file = new File (myDir, FILENAME);
    String string = "hello world!";
    FileOutputStream fos = new FileOutputStream(file);
    fos.write(string.getBytes());
    fos.close();
 }
 catch (IOException e) {
    e.printStackTrace();
 }

Well it seems that you are missing a reference to some library. I had the similar error solved it by adding a reference to the #pragma comment(lib, "windowscodecs.lib")

Step 1 - add permission request

    String[] permissionArrays = new String[]{Manifest.permission.CAMERA, 
    Manifest.permission.WRITE_EXTERNAL_STORAGE};
    int REQUEST_CODE = 101;

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

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            requestPermissions(permissionArrays, REQUEST_CODE );
        } else {
             // if already permition granted
            // PUT YOUR ACTION (Like Open cemara etc..)
        }
    }

Step 2 - Handle Permission result

     @Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    boolean openActivityOnce = true;
    boolean openDialogOnce = true;
    if (requestCode == REQUEST_CODE ) {
        for (int i = 0; i < grantResults.length; i++) {
            String permission = permissions[i];

            isPermitted = grantResults[i] == PackageManager.PERMISSION_GRANTED;

            if (grantResults[i] == PackageManager.PERMISSION_DENIED) {
                // user rejected the permission

            }else {
                //  user grant the permission
                // you can perfome your action 
            }
        }
    }
}

Since my original answer above, scanning vold is no longer viable across the various manufacturers.

I've developed a more reliable and straight forward method.

File mnt = new File("/storage");
if (!mnt.exists())
    mnt = new File("/mnt");

File[] roots = mnt.listFiles(new FileFilter() {

    @Override
    public boolean accept(File pathname) {
        return pathname.isDirectory() && pathname.exists()
                && pathname.canWrite() && !pathname.isHidden()
                && !isSymlink(pathname);
    }
});

roots will contain all the writeable root directories on the system, including any usb connected usb devices.

NOTE: The canWrite method needs the android.permission.WRITE_EXTERNAL_STORAGE permission.

Have in mind though, that getExternalStorageDirectory() is not going to work properly on some phones e.g. my Motorola razr maxx, as it has 2 cards /mnt/sdcard and /mnt/sdcard-ext - for internal and external SD cards respectfully. You will be getting the /mnt/sdcard only reply every time. Google must provide a way to deal with such a situation. As it renders many SD card aware apps (i.e card backup) failing miserably on these phones.

The reason is that the compiler has to actually see the definition in order to be able to drop it in in place of the call.

Remember that C and C++ use a very simplistic compilation model, where the compiler always only sees one translation unit at a time. (This fails for export, which is the main reason only one vendor actually implemented it.)

Add Permission to Android Manifest

Add this WRITE_EXTERNAL_STORAGE permission to your applications manifest.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="your.company.package"
    android:versionCode="1"
    android:versionName="0.1">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <!-- ... -->
    </application>
    <uses-sdk android:minSdkVersion="7" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
</manifest> 

Check availability of external storage

You should always check for availability first. A snippet from the official android documentation on external storage.

boolean mExternalStorageAvailable = false;
boolean mExternalStorageWriteable = false;
String state = Environment.getExternalStorageState();

if (Environment.MEDIA_MOUNTED.equals(state)) {
    // We can read and write the media
    mExternalStorageAvailable = mExternalStorageWriteable = true;
} else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
    // We can only read the media
    mExternalStorageAvailable = true;
    mExternalStorageWriteable = false;
} else {
    // Something else is wrong. It may be one of many other states, but all we need
    //  to know is we can neither read nor write
    mExternalStorageAvailable = mExternalStorageWriteable = false;
}

Use a Filewriter

At last but not least forget about the FileOutputStream and use a FileWriter instead. More information on that class form the FileWriter javadoc. You'll might want to add some more error handling here to inform the user.

// get external storage file reference
FileWriter writer = new FileWriter(getExternalStorageDirectory()); 
// Writes the content to the file
writer.write("This\n is\n an\n example\n"); 
writer.flush();
writer.close();

After searching for a long time this is what worked for me:

File file = new File(getPath(uri));


public String getPath(Uri uri) 
    {
        String[] projection = { MediaStore.Images.Media.DATA };
        Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
        if (cursor == null) return null;
        int column_index =             cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        String s=cursor.getString(column_index);
        cursor.close();
        return s;
    }

To use command support you should follow this steps:

1. Define Path in Environment Variables:

   • open 'System Properties';
   • on the tab 'Advanced' click on the 'Environment Variables' button
   • in the section 'System variables' select 'Path' option and click 'edit'

   • append variable value with the path to TortoiseProc.exe file, for example:

     C:\Program Files\TortoiseSVN\bin

2. Since you have registered TortoiseProc, you can use it in according to TortoiseSVN documentation.

   Examples:

   TortoiseProc.exe /command:commit /path:"c:\svn_wc\file1.txt*c:\svn_wc\file2.txt" /logmsg:"test log message" /closeonend:0

   TortoiseProc.exe /command:update /path:"c:\svn_wc\" /closeonend:0

   TortoiseProc.exe /command:log /path:"c:\svn_wc\file1.txt" /startrev:50 /endrev:60 /closeonend:0

P.S. To use friendly name like 'svn' instead of 'TortoiseProc', place 'svn.bat' file in the directory of 'TortoiseProc.exe'. There is an example of svn.bat:

TortoiseProc.exe %1 %2 %3

Try this code....

$chu = curl_init();

curl_setopt($chu, CURLOPT_URL, 'http://www.myapp.com/test.php?someprm=xyz');

curl_setopt($chu, CURLOPT_FRESH_CONNECT, true);
curl_setopt($chu, CURLOPT_TIMEOUT, 1);

curl_exec($chu);
curl_close($chu);

Please dont forget to enable CURL php extension.

I would have thought that something like this would be much better, since you're adding a variable, so why not restrict access and make it cleaner? Your getter/setters should do what they say on the tin.

public abstract class ExternalScript extends Script {

    private String source;

    public void setSource(String file) {
        source = file;
    }

    public String getSource() {
        return source;
    }
}

Bringing this back to the question, do you ever bother looking at where the getter/setter code is when reading it? If they all do getting and setting then you don't need to worry about what the function 'does' when reading the code. There are a few other reasons to think about too:

• If source was protected (so accessible by subclasses) then code gets messy: who's changing the variables? When it's an object it then becomes hard when you need to refactor, whereas a method tends to make this step easier.
• If your getter/setter methods aren't getting and setting, then describe them as something else.

Always think whether your class is really a different thing or not, and that should help decide whether you need anything more.

Is it a corporate Windows machine? If so aggressive virus scanners can really slow down modern IDEs. Check your task manager for processes that are using a lot of CPU or disk reads.

remote VisualSVN server 2.5.8 is accessible from at least 3 computers. However on my local computer the url of the repository was not accessible and svn ls https://server-ip:443/svn/project/trunk return error

OPTIONS of 'https://…' could not connect to server (…)

My local computer used to have access to the server. The only thing that was changed was switching to http connection instead of https for Redmine reasons(certificate issue).

I tried different things listed above. What actually solved my problem was installing a new the VisualSVN server 2.5.9 using the same repository. And also Redmine recognized the new repository through https.

</script> has to be broken up because otherwise it would end the enclosing <script></script> block too early. Really it should be split between the < and the /, because a script block is supposed (according to SGML) to be terminated by any end-tag open (ETAGO) sequence (i.e. </):

Although the STYLE and SCRIPT elements use CDATA for their data model, for these elements, CDATA must be handled differently by user agents. Markup and entities must be treated as raw text and passed to the application as is. The first occurrence of the character sequence "</" (end-tag open delimiter) is treated as terminating the end of the element's content. In valid documents, this would be the end tag for the element.

However in practice browsers only end parsing a CDATA script block on an actual </script> close-tag.

In XHTML there is no such special handling for script blocks, so any < (or &) character inside them must be &escaped; like in any other element. However then browsers that are parsing XHTML as old-school HTML will get confused. There are workarounds involving CDATA blocks, but it's easiest simply to avoid using these characters unescaped. A better way of writing a script element from script that works on either type of parser would be:

<script type="text/javascript">
    document.write('\x3Cscript type="text/javascript" src="foo.js">\x3C/script>');
</script>

You can put it like this

  assertTrue("your fail message ",Long.parseLong(previousTokenValues[1]) > Long.parseLong(currentTokenValues[1]));

Reverse the string and check if original string and reverse are same or not

While I agree with the others that you should not want it I'll just briefly explain what you can do to make a small difference without going all the way and actually blocking content that is already there -- maybe this will be enough to keep both you and your visitors happy.

The browser starts loading a page and will process externally located css and js later, especially if the place the css/js is linked is at the 'correct' place. (I think the advice is to load js as late as possible, and to use external css that you load in the header). Now if you have some portion of your css and/or js that you would like to be applied as soon as possible simply include that in the page itself. This will be against the advice of performance tools like YSlow but it probably will increase the change of your page showing up like you want it to be shown. Use this only when really needed!

Try this, replace ? with your schema name

select TABLE_NAME from  INFORMATION_SCHEMA.TABLES
 WHERE TABLE_SCHEMA =?
  AND TABLE_TYPE = 'BASE TABLE'

HTML - InputFile component can be hide by writing some css. Here I am adding an icon which overrides inputfile component.

<label class="custom-file-upload">
    <InputFile OnChange="HandleFileSelected" />
    <i class="fa fa-cloud-upload"></i> Upload
</label>

css-

<style>
    input[type="file"] {
        display: none;
    }

    .custom-file-upload {
        border: 1px solid #ccc;
        display: inline-block;
        padding: 6px 12px;
        cursor: pointer;

You can try this.

txt = <file_path>
txt_opn = open(txt)
print txt_opn.read()

This will give you file output.

props.children represents the content between the opening and the closing tags when invoking/rendering a component:

const Foo = props => (
  <div>
    <p>I'm {Foo.name}</p>
    <p>abc is: {props.abc}</p>

    <p>I have {props.children.length} children.</p>
    <p>They are: {props.children}.</p>
    <p>{Array.isArray(props.children) ? 'My kids are an array.' : ''}</p>
  </div>
);

const Baz = () => <span>{Baz.name} and</span>;
const Bar = () => <span> {Bar.name}</span>;

invoke/call/render Foo:

<Foo abc={123}>
  <Baz />
  <Bar />
</Foo>

not a good way but kind of quick fix, take a bool to check if in whole list there is any duplicate entry.

bool containsKey;
string newKey;

public void addKey(string newKey)
{
    foreach (string key in MyKeys)
    {
        if (key == newKey)
        {
            containsKey = true;
        }
    }

    if (!containsKey)
    {
        MyKeys.add(newKey);
    }
    else
    {
        containsKey = false;
    }
}

In iOS8 sizeWithFont has been deprecated, please refer to

CGSize yourLabelSize = [yourLabel.text sizeWithAttributes:@{NSFontAttributeName : [UIFont fontWithName:yourLabel.font size:yourLabel.fontSize]}];

You can add all the attributes you want in sizeWithAttributes. Other attributes you can set:

- NSForegroundColorAttributeName
- NSParagraphStyleAttributeName
- NSBackgroundColorAttributeName
- NSShadowAttributeName

and so on. But probably you won't need the others

<? php 

//1 Day = 24*60*60 = 86400

echo date("d-m-Y", time()+86400); 

?>

image container

Scaling images using the above trick only works if the container the images are in changes size.

The #icons container uses px values for the width and height. px values don't scale when the browser is resized.

Solutions

Use one of the following approaches:

1. Define the width and/or height using % values.
2. Use a series of @media queries to set the width and height to different values based on the current screen size.

<style>
#outer { text-align: center; }
#inner { width:500px; text-align: left; margin: 0 auto; }
.t { float: left; width:240px; border: 1px solid black;}
#clearit { clear: both; }
</style>

The issue, I believe, is that the Json action result is intended to take an object (your model) and create an HTTP response with content as the JSON-formatted data from your model object.

What you are passing to the controller's Json method, though, is a JSON-formatted string object, so it is "serializing" the string object to JSON, which is why the content of the HTTP response is surrounded by double-quotes (I'm assuming that is the problem).

I think you can look into using the Content action result as an alternative to the Json action result, since you essentially already have the raw content for the HTTP response available.

return this.Content(returntext, "application/json");
// not sure off-hand if you should also specify "charset=utf-8" here, 
//  or if that is done automatically

Another alternative would be to deserialize the JSON result from the service into an object and then pass that object to the controller's Json method, but the disadvantage there is that you would be de-serializing and then re-serializing the data, which may be unnecessary for your purposes.

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.

In PHP5, you should use the Document Object Model class instead. Example:

$domDoc = new DOMDocument;
$rootElt = $domDoc->createElement('root');
$rootNode = $domDoc->appendChild($rootElt);

$subElt = $domDoc->createElement('foo');
$attr = $domDoc->createAttribute('ah');
$attrVal = $domDoc->createTextNode('OK');
$attr->appendChild($attrVal);
$subElt->appendChild($attr);
$subNode = $rootNode->appendChild($subElt);

$textNode = $domDoc->createTextNode('Wow, it works!');
$subNode->appendChild($textNode);

echo htmlentities($domDoc->saveXML());

Thanks. Opening the URL connection by passing the Proxy as suggested by NickDK works fine.

//Proxy instance, proxy ip = 10.0.0.1 with port 8080
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("10.0.0.1", 8080));
conn = new URL(urlString).openConnection(proxy);

System properties however doesn't work as I had mentioned earlier.

Thanks again.

In addition Swiss Mister post, in my case the window.open was launched inside a promise, which turned the popup blocker on, my solution was: in angular:

$scope.gotClick = function(){

  var myNewTab = browserService.openNewTab();
  someService.getUrl().then(
    function(res){
        browserService.updateTabLocation(res.url, myNewTab);

    }
  );
};

browserService:

this.openNewTab = function(){
     var newTabWindow = $window.open();
     return newTabWindow;
}

this.updateTabLocation = function(tabLocation, tab) {
     if(!tabLocation){
       tab.close();
     }
     tab.location.href = tabLocation;
}

this is how you can open a new tab using the promise response and not invoking the popup blocker.

In your form are you passing in any other attributes, via mass assignment that don't belong to your user model, or any of the nested models?

If so, I believe the ActiveRecord::UnknownAttributeError is triggered in this instance.

Otherwise, I think you can just create your own controller, by generating something like this:

# app/controllers/registrations_controller.rb
class RegistrationsController < Devise::RegistrationsController
  def new
    super
  end

  def create
    # add custom create logic here
  end

  def update
    super
  end
end 

And then tell devise to use that controller instead of the default with:

# app/config/routes.rb
devise_for :users, :controllers => {:registrations => "registrations"}

the size attribute matters, if the size=5 then first 5 items will be shown and for others you need to scroll down..

<select name="numbers" size="5">
    <option>1</option>
    <option>2</option>
    <option>3</option>
    <option>4</option>
    <option>5</option>
    <option>6</option>
    <option>7</option>
</select>

No actual difference unless you get the type string. There when you use reflection or GetType() you get {Name = "Boolean" FullName = "System.Boolean"} for both.

I liked the simplest answer provided. However, I didn't like the choppiness of the collapsing. So I combined a solution from this question: How to Use slideDown (or show) function on a table row? to make it a smoother animation when the rows slide up or down. It involves having to wrap the content of each td in a div. This allows it to smoothly animate the collapsing. When the rows are expanded, it will replace the div, with just the content.

So here's the html:

<table>
<tr class="header">
    <td>CARS</td>
</tr>
<tr class="thing">
    <td>car</td>
</tr>
<tr class="thing">
    <td>truck</td>
</tr>
<tr class="header">
    <td>HOUSES</td>
</tr>
<tr class="thing">
    <td>split level</td>
</tr>
<tr class="thing">
    <td>trailer</td>
</tr>

And here's the js

$('.header').click(function(){
if($(this).hasClass("collapsed")){
    $(this).nextUntil('tr.header')
    .find('td')
    .parent()
    .find('td > div')
    .slideDown("fast", function(){
        var $set = $(this);
        $set.replaceWith($set.contents());
    });
    $(this).removeClass("collapsed");
} else {
    $(this).nextUntil('tr.header')
    .find('td')
    .wrapInner('<div style="display: block;" />')
    .parent()
    .find('td > div')
    .slideUp("fast");
    $(this).addClass("collapsed");
}
});

To run docker inside docker is definitely possible. The main thing is that you run the outer container with extra privileges (starting with --privileged=true) and then install docker in that container.

Check this blog post for more info: Docker-in-Docker.

One potential use case for this is described in this entry. The blog describes how to build docker containers within a Jenkins docker container.

However, Docker inside Docker it is not the recommended approach to solve this type of problems. Instead, the recommended approach is to create "sibling" containers as described in this post

So, running Docker inside Docker was by many considered as a good type of solution for this type of problems. Now, the trend is to use "sibling" containers instead. See the answer by @predmijat on this page for more info.

you can verify it in android ddms logcat where process id will be same but thread id will be different.

this works with "NA" not for NA

comments = c("no","yes","NA")
  for (l in 1:length(comments)) {
    #if (!is.na(comments[l])) print(comments[l])
    if (comments[l] != "NA") print(comments[l])
  }

Why I prefer Fragment over Activity in ALL CASES.

• Activity is expensive. In Fragment, views and property states are separated - whenever a fragment is in backstack, its views will be destroyed. So you can stack much more Fragments than Activity.

• Backstack manipulation. With FragmentManager, it's easy to clear all the Fragments, insert more than on Fragments and etcs. But for Activity, it will be a nightmare to manipulate those stuff.

• A much predictable lifecycle. As long as the host Activity is not recycled. the Fragments in the backstack will not be recycled. So it's possible to use FragmentManager::getFragments() to find specific Fragment (not encouraged).

you cant do this. Use a custom popup. Something like with the help of jQuery UI or jQuery BOXY.

Late to the party perhaps, but I wanted to share my take on this. I'm using a Builder pattern and allow conveniently chained append(more) calls, and allows mixing File and String. It can easily be extended to support working with Path objects as well, and furthermore handles the different path separators correctly on both Linux, Macintosh, etc.

public class Files  {
    public static class PathBuilder {
        private File file;

        private PathBuilder ( File root ) {
            file = root;
        }

        private PathBuilder ( String root ) {
            file = new File(root);
        }

        public PathBuilder append ( File more ) {
            file = new File(file, more.getPath()) );
            return this;
        }

        public PathBuilder append ( String more ) {
            file = new File(file, more);
            return this;
        }

        public File buildFile () {
            return file;
        }
    }

    public static PathBuilder buildPath ( File root ) {
        return new PathBuilder(root);
    }

    public static PathBuilder buildPath ( String root ) {
        return new PathBuilder(root);
    }
}

Example of usage:

File root = File.listRoots()[0];
String hello = "hello";
String world = "world";
String filename = "warez.lha"; 

File file = Files.buildPath(root).append(hello).append(world)
              .append(filename).buildFile();
String absolute = file.getAbsolutePath();

The resulting absolute will contain something like:

/hello/world/warez.lha

or maybe even:

A:\hello\world\warez.lha

When you specify position:absolute it positions itself to the next-highest element with position:relative. In this case, that's the .project div.

If you give the image's immediate parent div a style of position:relative, the overlay will key to that instead of the div which includes the text. For example: http://jsfiddle.net/7gYUU/1/

 <div class="parent">
    <img src="http://placehold.it/500x500" class="img-responsive"/>
    <div class="fa fa-plus project-overlay"></div>
 </div>

.parent {
   position: relative;
}

./me casts raise_dead()

I was looking for something like this, but I also needed to reuse the same string minus two parameters so I ended up with something like:

my_exe ()
{
    mysql -sN -e "select $1 from heat.stack where heat.stack.name=\"$2\";"
}

This is something I use to monitor openstack heat stack creation. In this case I expect two conditions, an action 'CREATE' and a status 'COMPLETE' on a stack named "Somestack"

To get those variables I can do something like:

ACTION=$(my_exe action Somestack)
STATUS=$(my_exe status Somestack)
if [[ "$ACTION" == "CREATE" ]] && [[ "$STATUS" == "COMPLETE" ]]
...

You will want to set the MdiParent property of your new form to the name of the MDI parent form, as follows:

dim form as new yourform
form.show()
form.MdiParent = nameParent

The problem is that the observable runs in another context, so when you try to create the URL var, you have an empty object and not the blob you want.

One of the many ways that exist to solve this is as follows:

this._reportService.getReport().subscribe(data => this.downloadFile(data)),//console.log(data),
                 error => console.log('Error downloading the file.'),
                 () => console.info('OK');

When the request is ready it will call the function "downloadFile" that is defined as follows:

downloadFile(data: Response) {
  const blob = new Blob([data], { type: 'text/csv' });
  const url= window.URL.createObjectURL(blob);
  window.open(url);
}

the blob has been created perfectly and so the URL var, if doesn't open the new window please check that you have already imported 'rxjs/Rx' ;

  import 'rxjs/Rx' ;

I hope this can help you.

If you use iOS 7 SDK, this is very simple.

Just add this line in your viewDidLoad method:

self.yourTableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

This answer got me 90% of the way there. I found the rest of my answer on the Microsoft site here.

The code below is what I'm using to target all ie by adding a .ie class to <html>

Use jQuery (which deprecated .browser in favor of user agents in 1.9+, see http://api.jquery.com/jQuery.browser/) to add an .ie class:

// ie identifier
$(document).ready(function () {
  if (navigator.appName == 'Microsoft Internet Explorer') {
    $("html").addClass("ie");
  }
});

Maybe jQuery UI does what you are looking for. Its composed out of many handy helper functions like making objects draggable, droppable, resizable, sortable etc.

Take a look at sortable with connected lists.

Source code of clear shows the reason why the newly added data gets the first position.

 public void clear() {
    modCount++;

    // Let gc do its work
    for (int i = 0; i < size; i++)
        elementData[i] = null;

    size = 0;
    }

clear() is faster than removeAll() by the way, first one is O(n) while the latter is O(n_2)

There isn't any direct equivalent to the goto concept in Java. There are a few constructs that allow you to do some of the things you can do with a classic goto.

• The break and continue statements allow you to jump out of a block in a loop or switch statement.
• A labeled statement and break <label> allow you to jump out of an arbitrary compound statement to any level within a given method (or initializer block).
• If you label a loop statement, you can continue <label> to continue with the next iteration of an outer loop from an inner loop.
• Throwing and catching exceptions allows you to (effectively) jump out of many levels of a method call. (However, exceptions are relatively expensive and are considered to be a bad way to do "ordinary" control flow¹.)
• And of course, there is return.

None of these Java constructs allow you to branch backwards or to a point in the code at the same level of nesting as the current statement. They all jump out one or more nesting (scope) levels and they all (apart from continue) jump downwards. This restriction helps to avoid the goto "spaghetti code" syndrome inherent in old BASIC, FORTRAN and COBOL code².

^{1- The most expensive part of exceptions is the actual creation of the exception object and its stacktrace. If you really, really need to use exception handling for "normal" flow control, you can either preallocate / reuse the exception object, or create a custom exception class that overrides the fillInStackTrace() method. The downside is that the exception's printStackTrace() methods won't give you useful information ... should you ever need to call them.}

^{2 - The spaghetti code syndrome spawned the structured programming approach, where you limited in your use of the available language constructs. This could be applied to BASIC, Fortran and COBOL, but it required care and discipline. Getting rid of goto entirely was a pragmatically better solution. If you keep it in a language, there is always some clown who will abuse it.}

Kotlin code is a lot simpler:

if(isVisable) {
    clearButton.visibility = View.INVISIBLE
}
else {
    clearButton.visibility = View.VISIBLE
}

You can convert a set into an ArrayList, where you can sort the ArrayList using Collections.sort(List).

Here is the code:

keySet = (Set) map.keySet();
ArrayList list = new ArrayList(keySet);     
Collections.sort(list);

You can try this solution

var d = new Date();
d.setTime(d.getTime());
var expires = "expires="+d.toUTCString();
document.cookie = 'COOKIE_NAME' + "=" + "" + ";domain=domain.com;path=/;" + expires;

Actually the mysql query for copy data from one table to another is

Insert into table2_name (column_names) select column_name from table1

where, the values copied from table1 to table2

Double check the virtual device you're trying to create has the same version on Genymotion that you have running.

I just upgraded to 2.1.1 but all the virtual devices I was trying to install were for 2.1.0. Downgrading Genymotion did the trick.

// Get the string from the URL
$json = file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452');

// Decode the JSON string into an object
$obj = json_decode($json);

// In the case of this input, do key and array lookups to get the values
var_dump($obj->results[0]->formatted_address);

For left padding add a string extension like this:

Swift 2.0 +

extension String {
    func padLeft (totalWidth: Int, with: String) -> String {
        let toPad = totalWidth - self.characters.count
        if toPad < 1 { return self }
        return "".stringByPaddingToLength(toPad, withString: with, startingAtIndex: 0) + self
    }
}

Swift 3.0 +

extension String {
    func padLeft (totalWidth: Int, with: String) -> String {
        let toPad = totalWidth - self.characters.count
        if toPad < 1 { return self }
        return "".padding(toLength: toPad, withPad: with, startingAt: 0) + self
    }
}

Using this method:

for myInt in 1...3 {
    print("\(myInt)".padLeft(totalWidth: 2, with: "0"))
}

For iOS, try:

var systemVersion = UIDevice.current.systemVersion

For OS X, try:

var systemVersion = NSProcessInfo.processInfo().operatingSystemVersion

If you just want to check if the users is running at least a specific version, you can also use the following Swift 2 feature which works on iOS and OS X:

if #available(iOS 9.0, *) {
    // use the feature only available in iOS 9
    // for ex. UIStackView
} else {
    // or use some work around
}

BUT it is not recommended to check the OS version. It is better to check if the feature you want to use is available on the device than comparing version numbers. For iOS, as mentioned above, you should check if it responds to a selector; eg.:

if (self.respondsToSelector(Selector("showViewController"))) {
    self.showViewController(vc, sender: self)
} else {
    // some work around
}

The error in the below line of code (as mentioned by the requestor-William) is due to the following reason:

fromBook.Sheets("Report").Copy Before:=newBook.Sheets("Sheet1")

The destination sheet you are trying to copy to is closed. (Here newbook.Sheets("Sheet1")). Add the below statement just before copying to destination.

Application.Workbooks.Open ("YOUR SHEET NAME")

This will solve the problem!!

First, the error you're getting is due to where you're using the COUNT function -- you can't use an aggregate (or group) function in the WHERE clause.

Second, instead of using a subquery, simply join the table to itself:

SELECT a.pid 
FROM Catalog as a LEFT JOIN Catalog as b USING( pid )
WHERE a.sid != b.sid
GROUP BY a.pid

Which I believe should return only rows where at least two rows exist with the same pid but there is are at least 2 sids. To make sure you get back only one row per pid I've applied a grouping clause.

Although the existing answers are valid approaches , they are antiquated . HttpClient is a modern interface for working with RESTful web services . Check the examples section of the page in the link , it has a very straightforward use case for an asynchronous HTTP GET .

using (var client = new System.Net.Http.HttpClient())
{
    return await client.GetStringAsync("https://reqres.in/api/users/3"); //uri
}

I'm not sure if this helps, but I needed to create a macro to hold a snippet, so I simply recorded myself inserting the items and set a shortcut to it. Granted, I'm not using version 5.9 so there might be some slight version differences. To access the macro recorder go to Macro > Start Recording. Then you will perform your action and then go to Macro > Stop Recording. I'd recommend playing it back to ensure it's correct and then save and set your shortcut key.

Hope the helps.

If you want to find the rows that have any of the values in a vector, one option is to loop the vector (lapply(v1,..)), create a logical index of (TRUE/FALSE) with (==). Use Reduce and OR (|) to reduce the list to a single logical matrix by checking the corresponding elements. Sum the rows (rowSums), double negate (!!) to get the rows with any matches.

indx1 <- !!rowSums(Reduce(`|`, lapply(v1, `==`, df)), na.rm=TRUE)

Or vectorise and get the row indices with which with arr.ind=TRUE

indx2 <- unique(which(Vectorize(function(x) x %in% v1)(df),
                                     arr.ind=TRUE)[,1])

Benchmarks

I didn't use @kristang's solution as it is giving me errors. Based on a 1000x500 matrix, @konvas's solution is the most efficient (so far). But, this may vary if the number of rows are increased

val <- paste0('M0', 1:1000)
set.seed(24)
df1 <- as.data.frame(matrix(sample(c(val, NA), 1000*500, 
  replace=TRUE), ncol=500), stringsAsFactors=FALSE) 
set.seed(356)
v1 <- sample(val, 200, replace=FALSE)

 konvas <- function() {apply(df1, 1, function(r) any(r %in% v1))}
 akrun1 <- function() {!!rowSums(Reduce(`|`, lapply(v1, `==`, df1)),
               na.rm=TRUE)}
 akrun2 <- function() {unique(which(Vectorize(function(x) x %in% 
              v1)(df1),arr.ind=TRUE)[,1])}


 library(microbenchmark)
 microbenchmark(konvas(), akrun1(), akrun2(), unit='relative', times=20L)
 #Unit: relative

You can use the below syntax -

from FolderName.FileName import Classname

Yes, it is a shorthand form of

int count;
if (isHere)
    count = getHereCount(index);
else
    count = getAwayCount(index);

It's called the conditional operator. Many people (erroneously) call it the ternary operator, because it's the only ternary (three-argument) operator in Java, C, C++, and probably many other languages. But theoretically there could be another ternary operator, whereas there can only be one conditional operator.

The official name is given in the Java Language Specification:

§15.25 Conditional Operator ? :

The conditional operator ? : uses the boolean value of one expression to decide which of two other expressions should be evaluated.

Note that both branches must lead to methods with return values:

It is a compile-time error for either the second or the third operand expression to be an invocation of a void method.

^{In fact, by the grammar of expression statements (§14.8), it is not permitted for a conditional expression to appear in any context where an invocation of a void method could appear.}

So, if doSomething() and doSomethingElse() are void methods, you cannot compress this:

if (someBool)
    doSomething();
else
    doSomethingElse();

into this:

someBool ? doSomething() : doSomethingElse();

Simple words:

booleanCondition ? executeThisPartIfBooleanConditionIsTrue : executeThisPartIfBooleanConditionIsFalse 

HTML5 + spark-md5 and Q

Assuming your'e using a modern browser (that supports HTML5 File API), here's how you calculate the MD5 Hash of a large file (it will calculate the hash on variable chunks)

function calculateMD5Hash(file, bufferSize) {
  var def = Q.defer();

  var fileReader = new FileReader();
  var fileSlicer = File.prototype.slice || File.prototype.mozSlice || File.prototype.webkitSlice;
  var hashAlgorithm = new SparkMD5();
  var totalParts = Math.ceil(file.size / bufferSize);
  var currentPart = 0;
  var startTime = new Date().getTime();

  fileReader.onload = function(e) {
    currentPart += 1;

    def.notify({
      currentPart: currentPart,
      totalParts: totalParts
    });

    var buffer = e.target.result;
    hashAlgorithm.appendBinary(buffer);

    if (currentPart < totalParts) {
      processNextPart();
      return;
    }

    def.resolve({
      hashResult: hashAlgorithm.end(),
      duration: new Date().getTime() - startTime
    });
  };

  fileReader.onerror = function(e) {
    def.reject(e);
  };

  function processNextPart() {
    var start = currentPart * bufferSize;
    var end = Math.min(start + bufferSize, file.size);
    fileReader.readAsBinaryString(fileSlicer.call(file, start, end));
  }

  processNextPart();
  return def.promise;
}

function calculate() {

  var input = document.getElementById('file');
  if (!input.files.length) {
    return;
  }

  var file = input.files[0];
  var bufferSize = Math.pow(1024, 2) * 10; // 10MB

  calculateMD5Hash(file, bufferSize).then(
    function(result) {
      // Success
      console.log(result);
    },
    function(err) {
      // There was an error,
    },
    function(progress) {
      // We get notified of the progress as it is executed
      console.log(progress.currentPart, 'of', progress.totalParts, 'Total bytes:', progress.currentPart * bufferSize, 'of', progress.totalParts * bufferSize);
    });
}

In your src/main/resources put an application.properties or application.yml and put a server.contextPath in there.

server.contextPath=/your/context/here

When starting your application the application will be available at http://localhost:8080/your/context/here.

For a comprehensive list of properties to set see Appendix A. of the Spring Boot reference guide.

Instead of putting it in the application.properties you can also pass it as a system property when starting your application

java -jar yourapp.jar -Dserver.contextPath=/your/path/here

Use 
 in place of \n this will change the line.

getline() is what you're looking for. You use strings in C++, and you don't need to know the size ahead of time.

Assuming std namespace:

 ifstream file1("myfile.txt");
 string stuff;

 while (getline(file1, stuff, '\n')) {
      cout << stuff << endl;
 }

 file1.close();

Create input element.

Missing from these answers is how to get a file dialog without a input element on the page.

The function to show the input file dialog.

function openFileDialog (accept, callback) {  // this function must be called from  a user
                                              // activation event (ie an onclick event)
    
    // Create an input element
    var inputElement = document.createElement("input");

    // Set its type to file
    inputElement.type = "file";

    // Set accept to the file types you want the user to select. 
    // Include both the file extension and the mime type
    inputElement.accept = accept;

    // set onchange event to call callback when user has selected file
    inputElement.addEventListener("change", callback)
    
    // dispatch a click event to open the file dialog
    inputElement.dispatchEvent(new MouseEvent("click")); 
}

NOTE the function must be part of a user activation such as a click event. Attempting to open the file dialog without user activation will fail.

NOTE input.accept is not used in Edge

Example.

Calling above function when user clicks an anchor element.

// wait for window to load
window.addEventListener("load", windowLoad);

// open a dialog function
function openFileDialog (accept, multy = false, callback) { 
    var inputElement = document.createElement("input");
    inputElement.type = "file";
    inputElement.accept = accept; // Note Edge does not support this attribute
    if (multy) {
        inputElement.multiple = multy;
    }
    if (typeof callback === "function") {
         inputElement.addEventListener("change", callback);
    }
    inputElement.dispatchEvent(new MouseEvent("click")); 
}

// onload event
function windowLoad () {
    // add user click event to userbutton
    userButton.addEventListener("click", openDialogClick);
}

// userButton click event
function openDialogClick () {
    // open file dialog for text files
    openFileDialog(".txt,text/plain", true, fileDialogChanged);
}

// file dialog onchange event handler
function fileDialogChanged (event) {
    [...this.files].forEach(file => {
        var div = document.createElement("div");
        div.className = "fileList common";
        div.textContent = file.name;
        userSelectedFiles.appendChild(div);
    });
}

.common {
    font-family: sans-serif;
    padding: 2px;
    margin : 2px;

_{Warning the above snippet is written in ES6.}

First example: No multiple threads. Both execute in single (existing) thread. No thread creation.

R1 r1 = new R1();
R2 r2 = new R2();

r1 and r2 are just two different objects of classes that implement the Runnable interface and thus implement the run() method. When you call r1.run() you are executing it in the current thread.

Second example: Two separate threads.

Thread t1 = new Thread(r1);
Thread t2 = new Thread(r2);

t1 and t2 are objects of the class Thread. When you call t1.start(), it starts a new thread and calls the run() method of r1 internally to execute it within that new thread.

make the utility class final and add a private constructor

this looks like PHP to me. I'll delete if it's some other language.

Simply unset($arr[1]);

There are already several answers however none of them mention the best (and easiest) way to do this, which is using spawn and the { stdio: 'inherit' } option. It seems to produce the most accurate output, for example when displaying the progress information from a git clone.

Simply do this:

var spawn = require('child_process').spawn;

spawn('coffee', ['-cw', 'my_file.coffee'], { stdio: 'inherit' });

With RSA Key then refer here

Snippet:

import pysftp
import paramiko
from base64 import decodebytes

keydata = b"""AAAAB3NzaC1yc2EAAAADAQABAAABAQDl""" 
key = paramiko.RSAKey(data=decodebytes(keydata)) 
cnopts = pysftp.CnOpts()
cnopts.hostkeys.add(host, 'ssh-rsa', key)


with pysftp.Connection(host=host, username=username, password=password, cnopts=cnopts) as sftp:   
  with sftp.cd(directory):
    sftp.put(file_to_sent_to_ftp)

You'll need to allocate memory for the new string otherString. In general for a substring of length n, something like this may work for you (don't forget to do bounds checking...)

char *subString(char *someString, int n) 
{
   char *new = malloc(sizeof(char)*n+1);
   strncpy(new, someString, n);
   new[n] = '\0';
   return new;
}

This will return a substring of the first n characters of someString. Make sure you free the memory when you are done with it using free().

# dump into file
pg_dump myDB > /tmp/myDB.sql

# create an empty db with the right encoding (on older versions the escaped single quotes are needed!)
psql -c 'CREATE DATABASE "tempDB" WITH OWNER = "myself" LC_COLLATE = '\''de_DE.utf8'\'' TEMPLATE template0;'

# import in the new DB
psql -d tempDB -1 -f /tmp/myDB.sql

# rename databases
psql -c 'ALTER DATABASE "myDB" RENAME TO "myDB_wrong_encoding";' 
psql -c 'ALTER DATABASE "tempDB" RENAME TO "myDB";'

# see the result
psql myDB -c "SHOW LC_COLLATE"   

Running the script like this (cron case for example): php5 /pathToScript/info.php produces the same error.

The correct way: php5 -cli /pathToScript/info.php

Easiest way to do this is close the project. Using file explorer head to the location of that project and delete.

Alot of processes, even simply deleting can be annoying to figure out in studio. Most deleting options a good work around is to delete using file explorer. This is a part of the process tht works for deleting modules as well. Which u will prob find is painful as well

If its ubuntu then go ahead with this, already tested.:--

first, installing dependencies

sudo aptitude install openssl build-essential xorg libssl-dev

for 64bits OS

wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-amd64.tar.bz2 
tar xvjf wkhtmltopdf-0.9.9-static-amd64.tar.bz2
mv wkhtmltopdf-amd64 /usr/local/bin/wkhtmltopdf
chmod +x /usr/local/bin/wkhtmltopdf

for 32bits OS

wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-i386.tar.bz2 
tar xvjf wkhtmltopdf-0.9.9-static-i386.tar.bz2
 mv wkhtmltopdf-i386 /usr/local/bin/wkhtmltopdf
chmod +x /usr/local/bin/wkhtmltopdf

for me the "workaround" solution was to remove the "_normal" from the end of the string

Check it out below:

• Low res image: https://pbs.twimg.com/profile_images/636894769742897152/frlgaWB8_normal.jpg

• Hi res image: https://pbs.twimg.com/profile_images/636894769742897152/frlgaWB8.jpg

To expand on katrmr's answer, if the container is stopped and can't be started due to an error, you'll need to commit it to an image. Then you can launch bash in the new image:

docker commit [CONTAINER_ID] temporary_image
docker run --entrypoint=bash -it temporary_image

I'm not convinced your algorithm is anything but efficient. It's O(n) and only looks at each character once. You're not gonna get any better than that unless you magically know values before checking them.

I would however initialize the capacity of your StringBuilder to the initial size of the string. I'm guessing your perceived performance problem comes from memory reallocation.

Side note: Checking A-z is not safe. You're including [, \, ], ^, _, and `...

Side note 2: For that extra bit of efficiency, put the comparisons in an order to minimize the number of comparisons. (At worst, you're talking 8 comparisons tho, so don't think too hard.) This changes with your expected input, but one example could be:

if (str[i] >= '0' && str[i] <= 'z' && 
    (str[i] >= 'a' || str[i] <= '9' ||  (str[i] >= 'A' && str[i] <= 'Z') || 
    str[i] == '_') || str[i] == '.')

Side note 3: If for whatever reason you REALLY need this to be fast, a switch statement may be faster. The compiler should create a jump table for you, resulting in only a single comparison:

switch (str[i])
{
    case '0':
    case '1':
    .
    .
    .
    case '.':
        sb.Append(str[i]);
        break;
}

I added this to my package.json:

"build": "npm build",
"clean": "rm -rf node_modules", 
"reinstall": "npm run clean && npm install", 
"rebuild": "npm run clean && npm install && npm run build",

Seems to work well.

Now require-dev is enabled by default, for local development you can do composer install and composer update without the --dev option.

When you want to deploy to production, you'll need to make sure composer.lock doesn't have any packages that came from require-dev.

You can do this with

composer update --no-dev

Once you've tested locally with --no-dev you can deploy everything to production and install based on the composer.lock. You need the --no-dev option again here, otherwise composer will say "The lock file does not contain require-dev information".

composer install --no-dev

Note: Be careful with anything that has the potential to introduce differences between dev and production! I generally try to avoid require-dev wherever possible, as including dev tools isn't a big overhead.

In addition to kiran's post, there's the update helper (formerly a react addon). This can be installed with npm using npm install immutability-helper

import update from 'immutability-helper';

var abc = update(this.state.abc, {
   xyz: {$set: 'foo'}
});

this.setState({abc: abc});

This creates a new object with the updated value, and other properties stay the same. This is more useful when you need to do things like push onto an array, and set some other value at the same time. Some people use it everywhere because it provides immutability.

If you do this, you can have the following to make up for the performance of

shouldComponentUpdate: function(nextProps, nextState){
   return this.state.abc !== nextState.abc; 
   // and compare any props that might cause an update
}

You are using images to submit.. so you can simply use an type="image" input "button":

<input type="image" src="yourimage.png" name="yourinputname" value="yourinputvalue" />

This is a working BackButton component (React 0.14):

var React = require('react');
var Router = require('react-router');

var History = Router.History;

var BackButton = React.createClass({
  mixins: [ History ],
  render: function() {
    return (
      <button className="back" onClick={this.history.goBack}>{this.props.children}</button>
    );
  }
});

module.exports = BackButton;

You can off course do something like this if there is no history:

<button className="back" onClick={goBack}>{this.props.children}</button>

function goBack(e) {
  if (/* no history */) {
    e.preventDefault();
  } else {
    this.history.goBack();
  }
}

You've already done it correctly by using a DateTime parameter with the value from the DateTime, so it should already work. Forget about ToString() - since that isn't used here.

If there is a difference, it is most likely to do with different precision between the two environments; maybe choose a rounding (seconds, maybe?) and use that. Also keep in mind UTC/local/unknown (the DB has no concept of the "kind" of date; .NET does).

I have a table and the date-times in it are in the format: 2011-07-01 15:17:33.357

Note that datetimes in the database aren't in any such format; that is just your query-client showing you white lies. It is stored as a number (and even that is an implementation detail), because humans have this odd tendency not to realise that the date you've shown is the same as 40723.6371916281. Stupid humans. By treating it simply as a "datetime" throughout, you shouldn't get any problems.

C# 6 adds a new feature just for this: extension Add methods. This has always been possible for VB.net but is now available in C#.

Now you don't have to add Add() methods to your classes directly, you can implement them as extension methods. When extending any enumerable type with an Add() method, you'll be able to use it in collection initializer expressions. So you don't have to derive from lists explicitly anymore (as mentioned in another answer), you can simply extend it.

public static class TupleListExtensions
{
    public static void Add<T1, T2>(this IList<Tuple<T1, T2>> list,
            T1 item1, T2 item2)
    {
        list.Add(Tuple.Create(item1, item2));
    }

    public static void Add<T1, T2, T3>(this IList<Tuple<T1, T2, T3>> list,
            T1 item1, T2 item2, T3 item3)
    {
        list.Add(Tuple.Create(item1, item2, item3));
    }

    // and so on...
}

This will allow you to do this on any class that implements IList<>:

var numbers = new List<Tuple<int, string>>
{
    { 1, "one" },
    { 2, "two" },
    { 3, "three" },
    { 4, "four" },
    { 5, "five" },
};
var points = new ObservableCollection<Tuple<double, double, double>>
{
    { 0, 0, 0 },
    { 1, 2, 3 },
    { -4, -2, 42 },
};

Of course you're not restricted to extending collections of tuples, it can be for collections of any specific type you want the special syntax for.

public static class BigIntegerListExtensions
{
    public static void Add(this IList<BigInteger> list,
        params byte[] value)
    {
        list.Add(new BigInteger(value));
    }

    public static void Add(this IList<BigInteger> list,
        string value)
    {
        list.Add(BigInteger.Parse(value));
    }
}

var bigNumbers = new List<BigInteger>
{
    new BigInteger(1), // constructor BigInteger(int)
    2222222222L,       // implicit operator BigInteger(long)
    3333333333UL,      // implicit operator BigInteger(ulong)
    { 4, 4, 4, 4, 4, 4, 4, 4 },               // extension Add(byte[])
    "55555555555555555555555555555555555555", // extension Add(string)
};

C# 7 will be adding in support for tuples built into the language, though they will be of a different type (System.ValueTuple instead). So to it would be good to add overloads for value tuples so you have the option to use them as well. Unfortunately, there are no implicit conversions defined between the two.

public static class ValueTupleListExtensions
{
    public static void Add<T1, T2>(this IList<Tuple<T1, T2>> list,
        ValueTuple<T1, T2> item) => list.Add(item.ToTuple());
}

This way the list initialization will look even nicer.

var points = new List<Tuple<int, int, int>>
{
    (0, 0, 0),
    (1, 2, 3),
    (-1, 12, -73),
};

But instead of going through all this trouble, it might just be better to switch to using ValueTuple exclusively.

var points = new List<(int, int, int)>
{
    (0, 0, 0),
    (1, 2, 3),
    (-1, 12, -73),
};

This is how you would drop the constraint

ALTER TABLE <schema_name, sysname, dbo>.<table_name, sysname, table_name>
   DROP CONSTRAINT <default_constraint_name, sysname, default_constraint_name>
GO

With a script

-- t-sql scriptlet to drop all constraints on a table
DECLARE @database nvarchar(50)
DECLARE @table nvarchar(50)

set @database = 'dotnetnuke'
set @table = 'tabs'

DECLARE @sql nvarchar(255)
WHILE EXISTS(select * from INFORMATION_SCHEMA.TABLE_CONSTRAINTS where constraint_catalog = @database and table_name = @table)
BEGIN
    select    @sql = 'ALTER TABLE ' + @table + ' DROP CONSTRAINT ' + CONSTRAINT_NAME 
    from    INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
    where    constraint_catalog = @database and 
            table_name = @table
    exec    sp_executesql @sql
END

I've solved the problem , and I will explain how :

1. Download Github For Windows client and install it.
2. After The client successfully installed , connect it with your github account.It should be easy , just follow the wizard.
3. Then you should add git.exe location to your "Path Variable". The location you should add will probably be something like : C:\Users\Your_Username\AppData\Local\GitHub\PortableGit_ca477551eeb4aea0e4ae9fcd3358bd96720bb5c8\bin

Alternatively , if you don't want to add to environment variables. You can open the android studio and go to : Settings -> Version Control -> Git In text box next to "Path to Git Executable" you will see "git.exe" , just give it a full path like so : C:\Users\Your_Username\AppData\Local\GitHub\PortableGit_ca477551eeb4aea0e4ae9fcd3358bd96720bb5c8\bin\git.exe

Hope it saved your time . Happy coding :)

EDIT : For latest Github for windows versions some can find the git.exe under "...\cmd\git.exe" rather than "...\bin\git.exe".

You can also modify the windowTitle attribute in Qt Designer.

axios signature for post is axios.post(url[, data[, config]]). So you want to send params object within the third argument:

.post(`/mails/users/sendVerificationMail`, null, { params: {
  mail,
  firstname
}})
.then(response => response.status)
.catch(err => console.warn(err));

This will POST an empty body with the two query params:

POST http://localhost:8000/api/mails/users/sendVerificationMail?mail=lol%40lol.com&firstname=myFirstName

You can do this by reading from the boolean property at:

System.Web.Security.Roles.Enabled

This is a direct read from the enabled attribute of the roleManager element in the web.config:

<configuration>
  <system.web>
    <roleManager enabled="true" />
  </system.web>
</configuration>

One easy solution is to use overflow values other than visible to make the text flex basis width reset as expected.

1. Here with value auto the text wraps as expected and the article content does not overflow main container.

2. Also, the article flex value must either have a auto basis AND be able to shrink, OR, only grow AND explicit 0 basis

Everyone is right. You can't print an int[] object out directly, but there's also no need to not use an ArrayList of integer arrays.

Using,

Arrays.toString(arl.get(0))

means splitting the String object into a substring if you want to insert anything in between, such as commas.

Here's what I think amv was looking for from an int array viewpoint.

System.out.println("Arraylist contains: " 
    + arl.get(0)[0] + ", " 
    + arl.get(0)[1] + ", " 
    + arl.get(0)[2]);

This answer is a little late for amv but still may be useful to others.

There are multiple ways to get the last inserted ID after insert command.

1. @@IDENTITY : It returns the last Identity value generated on a Connection in current session, regardless of Table and the scope of statement that produced the value
2. SCOPE_IDENTITY(): It returns the last identity value generated by the insert statement in the current scope in the current connection regardless of the table.
3. IDENT_CURRENT(‘TABLENAME’) : It returns the last identity value generated on the specified table regardless of Any connection, session or scope. IDENT_CURRENT is not limited by scope and session; it is limited to a specified table.

Now it seems more difficult to decide which one will be exact match for my requirement.

I mostly prefer SCOPE_IDENTITY().

If you use select SCOPE_IDENTITY() along with TableName in insert statement, you will get the exact result as per your expectation.

After you correct the possible dmp file problem, this is a way to ensure that the schema is remapped and imported appropriately. This will also ensure that the tablespace will change also, if needed:

impdp system/<password> SCHEMAS=user1 remap_schema=user1:user2 \
            remap_tablespace=user1:user2 directory=EXPORTDIR \
            dumpfile=user1.dmp logfile=E:\Data\user1.log

EXPORTDIR must be defined in oracle as a directory as the system user

create or replace directory EXPORTDIR as 'E:\Data';
grant read, write on directory EXPORTDIR to user2;

1. Using the x509 module
openssl x509 ...
...

2 Using the ca module
openssl ca ...
...

You are missing the prelude to those commands.

This is a two-step process. First you set up your CA, and then you sign an end entity certificate (a.k.a server or user). Both of the two commands elide the two steps into one. And both assume you have a an OpenSSL configuration file already setup for both CAs and Server (end entity) certificates.

First, create a basic configuration file:

$ touch openssl-ca.cnf

Then, add the following to it:

keyUsage               = keyCertSign, cRLSign

The fields above are taken from a more complex openssl.cnf (you can find it in /usr/lib/openssl.cnf), but I think they are the essentials for creating the CA certificate and private key.

Tweak the fields above to suit your taste. The defaults save you the time from entering the same information while experimenting with configuration file and command options.

I omitted the CRL-relevant stuff, but your CA operations should have them. See openssl.cnf and the related crl_ext section.

Then, execute the following. The -nodes omits the password or passphrase so you can examine the certificate. It's a really bad idea to omit the password or passphrase.

$ openssl req -x509 -config openssl-ca.cnf -newkey rsa:4096 -sha256 -nodes -out cacert.pem -outform PEM

After the command executes, cacert.pem will be your certificate for CA operations, and cakey.pem will be the private key. Recall the private key does not have a password or passphrase.

You can dump the certificate with the following.

$ openssl x509 -in cacert.pem -text -noout

For part two, I'm going to create another configuration file that's easily digestible. First, touch the openssl-server.cnf (you can make one of these for user certificates also).

$ touch openssl-server.cnf

Then open it, and add the following.

HOME            = .
RANDFILE        = $ENV::HOME/.rnd

If you are developing and need to use your workstation as a server, then you may need to do the following for Chrome. Otherwise Chrome may complain a Common Name is invalid (ERR_CERT_COMMON_NAME_INVALID). I'm not sure what the relationship is between an IP address in the SAN and a CN in this instance.

# IPv4 localhost
IP.1     = 127.0.0.1

# IPv6 localhost
IP.2     = ::1

Then, create the server certificate request. Be sure to omit -x509*. Adding -x509 will create a certificate, and not a request.

$ openssl req -config openssl-server.cnf -newkey rsa:2048 -sha256 -nodes -out servercert.csr -outform PEM

After this command executes, you will have a request in servercert.csr and a private key in serverkey.pem.

And you can inspect it again.

$ openssl req -text -noout -verify -in servercert.csr

Next, you have to sign it with your CA.

You are almost ready to sign the server's certificate by your CA. The CA's openssl-ca.cnf needs two more sections before issuing the command.

First, open openssl-ca.cnf and add the following two sections.

####################################################################
[ signing_policy ]
countryName            = optional
stateOrProvinceName    = optional
localityName           = optional
organizationName       = optional
organizationalUnitName = optional
commonName             = supplied
emailAddress           = optional

####################################################################
[ signing_req ]
subjectKeyIdentifier   = hash
authorityKeyIdentifier = keyid,issuer
basicConstraints       = CA:FALSE
keyUsage               = digitalSignature, keyEncipherment

Second, add the following to the [ CA_default ] section of openssl-ca.cnf. I left them out earlier, because they can complicate things (they were unused at the time). Now you'll see how they are used, so hopefully they will make sense.

base_dir      = .
certificate   = $base_dir/cacert.pem   # The CA certifcate
private_key   = $base_dir/cakey.pem    # The CA private key
new_certs_dir = $base_dir              # Location for new certs after signing
database      = $base_dir/index.txt    # Database index file
serial        = $base_dir/serial.txt   # The current serial number

unique_subject = no  # Set to 'no' to allow creation of
                     # several certificates with same subject.

Third, touch index.txt and serial.txt:

$ touch index.txt
$ echo '01' > serial.txt

Then, perform the following:

$ openssl ca -config openssl-ca.cnf -policy signing_policy -extensions signing_req -out servercert.pem -infiles servercert.csr

You should see similar to the following:

Using configuration from openssl-ca.cnf
Check that the request matches the signature
Signature ok
The Subject's Distinguished Name is as follows
countryName           :PRINTABLE:'US'
stateOrProvinceName   :ASN.1 12:'MD'
localityName          :ASN.1 12:'Baltimore'
commonName            :ASN.1 12:'Test CA'
emailAddress          :IA5STRING:'[email protected]'

Sign the certificate? [y/n]:Y

1 out of 1 certificate requests certified, commit? [y/n]Y

After the command executes, you will have a freshly minted server certificate in servercert.pem. The private key was created earlier and is available in serverkey.pem.

Finally, you can inspect your freshly minted certificate with the following:

$ openssl x509 -in servercert.pem -text -noout

Earlier, you added the following to CA_default: copy_extensions = copy. This copies extension provided by the person making the request.

If you omit copy_extensions = copy, then your server certificate will lack the Subject Alternate Names (SANs) like www.example.com and mail.example.com.

If you use copy_extensions = copy, but don't look over the request, then the requester might be able to trick you into signing something like a subordinate root (rather than a server or user certificate). Which means he/she will be able to mint certificates that chain back to your trusted root. Be sure to verify the request with openssl req -verify before signing.

If you omit unique_subject or set it to yes, then you will only be allowed to create one certificate under the subject's distinguished name.

unique_subject = yes            # Set to 'no' to allow creation of
                                # several ctificates with same subject.

Trying to create a second certificate while experimenting will result in the following when signing your server's certificate with the CA's private key:

Sign the certificate? [y/n]:Y
failed to update database
TXT_DB error number 2

So unique_subject = no is perfect for testing.

If you want to ensure the Organizational Name is consistent between self-signed CAs, Subordinate CA and End-Entity certificates, then add the following to your CA configuration files:

[ policy_match ]
organizationName = match

If you want to allow the Organizational Name to change, then use:

[ policy_match ]
organizationName = supplied

There are other rules concerning the handling of DNS names in X.509/PKIX certificates. Refer to these documents for the rules:

• RFC 5280, Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile
• RFC 6125, Representation and Verification of Domain-Based Application Service Identity within Internet Public Key Infrastructure Using X.509 (PKIX) Certificates in the Context of Transport Layer Security (TLS)
• RFC 6797, Appendix A, HTTP Strict Transport Security (HSTS)
• RFC 7469, Public Key Pinning Extension for HTTP
• CA/Browser Forum Baseline Requirements
• CA/Browser Forum Extended Validation Guidelines

RFC 6797 and RFC 7469 are listed, because they are more restrictive than the other RFCs and CA/B documents. RFC's 6797 and 7469 do not allow an IP address, either.

As @StahlRat already answered. I would like to add another method for it. There is extension pack for Python Default idle editor Python Extensions Package.

The first parameter to the iterator in forEach is the value and second is the key of the object.

angular.forEach(objectToIterate, function(value, key) {
    /* do something for all key: value pairs */
});

In your example, the outer forEach is actually:

angular.forEach($scope.filters, function(filterObj , filterKey)

Since I couldn't find confirmation of this anywhere, I tested if disposing of the MailMessage and/or the Attachment object would dispose of the stream loaded into them as I expected would happen.

It does appear with the following test that when the MailMessage is disposed, all streams used to create attachments will also be disposed. So as long as you dispose your MailMessage the streams that went into creating it do not need handling beyond that.

MailMessage mail = new MailMessage();
//Create a MemoryStream from a file for this test
MemoryStream ms = new MemoryStream(File.ReadAllBytes(@"C:\temp\test.gif"));

mail.Attachments.Add(new System.Net.Mail.Attachment(ms, "test.gif"));
if (mail.Attachments[0].ContentStream == ms) Console.WriteLine("Streams are referencing the same resource");
Console.WriteLine("Stream length: " + mail.Attachments[0].ContentStream.Length);

//Dispose the mail as you should after sending the email
mail.Dispose();
//--Or you can dispose the attachment itself
//mm.Attachments[0].Dispose();

Console.WriteLine("This will throw a 'Cannot access a closed Stream.' exception: " + ms.Length);

REST is very abstract. It helps to have some good, simple, real-world examples.

Take for example all major social media apps -- Tumblr, Instagram, Facebook, and Twitter. They all have a forever-scrolling view where the farther you scroll down, the more content you see, further and further back in time. However, we've all experienced that moment where you lose where you were scrolled to, and the app resets you back to the top. Like if you quit the app, then when you reopen it, you're back at the top again.

The reason why, is because the server did not store your session state. Sadly, your scroll position was just stored in RAM on the client.

Fortunately you don't have to log back in when you reconnect, but that's only because your client-side also stored login certificate has not expired. Delete and reinstall the app, and you're going to have to log back in, because the server did not associate your IP address with your session.

You don't have a login session on the server, because they abide by REST.

Now the above examples don't involve a web browser at all, but on the back end, the apps are communicating via HTTPS with their host servers. My point is that REST does not have to involve cookies and browsers etc. There are various means of storing client-side session state.

But lets talk about web browsers for a second, because that brings up another major advantage of REST that nobody here is talking about.

If the server tried to store session state, how is it supposed to identify each individual client?

It could not use their IP address, because many people could be using that same address on a shared router. So how, then?

It can't use MAC address for many reasons, not the least of which because you can be logged into multiple different Facebook accounts simultaneously on different browsers plus the app. One browser can easily pretend to be another one, and MAC addresses are just as easy to spoof.

If the server has to store some client-side state to identify you, it has to store it in RAM longer than just the time it takes to process your requests, or else it has to cache that data. Servers have limited amounts of RAM and cache, not to mention processor speed. Server-side state adds to all three, exponentially. Plus if the server is going to store any state about your sessions then it has to store it separately for each browser and app you're currently logged in with, and also for each different device you use.

So... I hope that you see now why REST is so important for scalability. I hope you can start to see why server-side session state is to server scalability what welded-on anvils are to car acceleration.

Where people get confused is by thinking that "state" refers to, like, information stored in a database. No, it refers to any information that needs to be in the RAM of the server when you're using it.

Failure [INSTALL_FAILED_USER_RESTRICTED: Install canceled by user]:

Go to Settings->Additional Settings->Developer options->Developer Option(Need to enable)->USB debugging(Need to enable)->Install via USB (Need to enable)->USB debugging (Security settings)(Need to enable)

Perfectly working in the above steps.

Enjoy your coding...

I've been testing v4 for a few days now and .. I'm loving it so far! It just makes sense after a while.

I also had the same question and I found handling it like the following worked best (and might even be how it is intended). It uses state, a ternary operator and <Redirect>.

In the constructor()

this.state = {
    redirectTo: null
} 
this.clickhandler = this.clickhandler.bind(this);

In the render()

render(){
    return (
        <div>
        { this.state.redirectTo ?
            <Redirect to={{ pathname: this.state.redirectTo }} /> : 
            (
             <div>
               ..
             <button onClick={ this.clickhandler } />
              ..
             </div>
             )
         }

In the clickhandler()

 this.setState({ redirectTo: '/path/some/where' });

Hope it helps. Let me know.

On Ubuntu:

sudo apt install ca-certificates-java

or

sudo apt-get install ca-certificates-java

sorted it for me.

If you want to find one element or None use default in next, it won't raise StopIteration if the item was not found in the list:

first_or_default = next((x for x in lst if ...), None)

Try below code:

public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

        getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));// set transparent in window background

        View _v = inflater.inflate(R.layout.some_you_layout, container, false);

        //load animation
        //Animation transition_in_view = AnimationUtils.loadAnimation(getContext(), android.R.anim.fade_in);// system animation appearance
        Animation transition_in_view = AnimationUtils.loadAnimation(getContext(), R.anim.customer_anim);//customer animation appearance

        _v.setAnimation( transition_in_view );
        _v.startAnimation( transition_in_view );
        //really beautiful
        return _v;

    }

Create the custom Anim.: res/anim/customer_anim.xml:

<?xml version="1.0" encoding="utf-8"?>

    <translate

If column A contains the amounts to be reimbursed, and column B contains the "yes/no" indicating whether the reimbursement has been made, then either of the following will work, though the first option is recommended:

=SUMIF(B:B,"No",A:A)

or

=SUMIFS(A:A,B:B,"No")

Here is an example that will display the amounts paid and outstanding for a small set of sample data.

 A         B            C                   D
 Amount    Reimbursed?  Total Paid:         =SUMIF(B:B,"Yes",A:A)
 $100      Yes          Total Outstanding:  =SUMIF(B:B,"No",A:A)
 $200      No           
 $300      No
 $400      Yes
 $500      No

I looked all over for an easy solution and found this code that worked for me. The right div is a third column which I left in for readability sake.

Here is the HTML:

<div class="container">
  <div class="row">
    <div class="left">
      <p>PHONE & FAX:</p>
    </div>
    <div class="middle">
      <p>+43 99 554 28 53</p>
    </div>
    <div class="right"> </div>
  </div>
  <div class="row">
    <div class="left">
      <p>Cellphone Gert:</p>
    </div>
    <div class="middle">
      <p>+43 99 302 52 32</p>
    </div>
    <div class="right"> </div>
  </div>
  <div class="row">
    <div class="left">
      <p>Cellphone Petra:</p>
    </div>
    <div class="middle">
      <p>+43 99 739 38 84</p>
    </div>
    <div class="right"> </div>
  </div>
</div>

And the CSS:

.container {
    display: table;
    }
.row  {
    display: table-row;
    }
.left, .right, .middle {
    display: table-cell;
    padding-right: 25px;
    }
.left p, .right p, .middle p {
    margin: 1px 1px;
   }

Another easy way is :

 function getIndex(items) {
        for (const [index, item] of items.entries()) {
            if (item.prop2 === 'yutu') {
                return index;
            }
        }
    }

const myIndex = getIndex(myArray);

As of the 0.17.0 release, the sort method was deprecated in favor of sort_values. sort was completely removed in the 0.20.0 release. The arguments (and results) remain the same:

df.sort_values(['a', 'b'], ascending=[True, False])

You can use the ascending argument of sort:

df.sort(['a', 'b'], ascending=[True, False])

For example:

In [11]: df1 = pd.DataFrame(np.random.randint(1, 5, (10,2)), columns=['a','b'])

In [12]: df1.sort(['a', 'b'], ascending=[True, False])
Out[12]:
   a  b
2  1  4
7  1  3
1  1  2
3  1  2
4  3  2
6  4  4
0  4  3
9  4  3
5  4  1
8  4  1

As commented by @renadeen

Sort isn't in place by default! So you should assign result of the sort method to a variable or add inplace=True to method call.

that is, if you want to reuse df1 as a sorted DataFrame:

df1 = df1.sort(['a', 'b'], ascending=[True, False])

or

df1.sort(['a', 'b'], ascending=[True, False], inplace=True)

No, but you can use the Builder Pattern, as described in this Stack Overflow answer.

As described in the linked answer, the Builder Pattern lets you write code like

Student s1 = new StudentBuilder().name("Eli").buildStudent();
Student s2 = new StudentBuilder()
                 .name("Spicoli")
                 .age(16)
                 .motto("Aloha, Mr Hand")
                 .buildStudent();

in which some fields can have default values or otherwise be optional.

This works for up to 5 dates and handles nulls. Just couldn't get it to work as an Inline function.

CREATE FUNCTION dbo.MinDate(@Date1 datetime = Null,
                            @Date2 datetime = Null,
                            @Date3 datetime = Null,
                            @Date4 datetime = Null,
                            @Date5 datetime = Null)
RETURNS Datetime AS
BEGIN
--USAGE select dbo.MinDate('20120405',null,null,'20110305',null)
DECLARE @Output datetime;

WITH Datelist_CTE(DT)
AS (
        SELECT @Date1 AS DT WHERE @Date1 is not NULL UNION
        SELECT @Date2 AS DT WHERE @Date2 is not NULL UNION
        SELECT @Date3 AS DT WHERE @Date3 is not NULL UNION
        SELECT @Date4 AS DT WHERE @Date4 is not NULL UNION
        SELECT @Date5 AS DT WHERE @Date5 is not NULL
   )
Select @Output=Min(DT) FROM Datelist_CTE

RETURN @Output
END

Another way to do it, is creating a custom component extending TextView. It's good for cases where you need to have multiple underlined TextViews.

Here's the code for the component:

package com.myapp.components;

import android.content.Context;
import android.support.v7.widget.AppCompatTextView;
import android.text.SpannableString;
import android.text.style.UnderlineSpan;
import android.util.AttributeSet;

public class LinkTextView extends AppCompatTextView {
    public LinkTextView(Context context) {
        this(context, null);
    }

    public LinkTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void setText(CharSequence text, BufferType type) {
        SpannableString content = new SpannableString(text);
        content.setSpan(new UnderlineSpan(), 0, content.length(), 0);

        super.setText(content, type);
    }
}

And how to use it in xml:

<com.myapp.components.LinkTextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Hello World!" />

for a = 1 to 100 step 1

Command line in Windows . Please use %%a if running in Batch file.

    for /L %a in (1,1,100) Do echo %a 

You'll want to use the process.argv array to access the command-line arguments to get the filename and the FileSystem module (fs) to read the file. For example:

// Make sure we got a filename on the command line.
if (process.argv.length < 3) {
  console.log('Usage: node ' + process.argv[1] + ' FILENAME');
  process.exit(1);
}
// Read the file and print its contents.
var fs = require('fs')
  , filename = process.argv[2];
fs.readFile(filename, 'utf8', function(err, data) {
  if (err) throw err;
  console.log('OK: ' + filename);
  console.log(data)
});

To break that down a little for you process.argv will usually have length two, the zeroth item being the "node" interpreter and the first being the script that node is currently running, items after that were passed on the command line. Once you've pulled a filename from argv then you can use the filesystem functions to read the file and do whatever you want with its contents. Sample usage would look like this:

$ node ./cat.js file.txt
OK: file.txt
This is file.txt!

[Edit] As @wtfcoder mentions, using the "fs.readFile()" method might not be the best idea because it will buffer the entire contents of the file before yielding it to the callback function. This buffering could potentially use lots of memory but, more importantly, it does not take advantage of one of the core features of node.js - asynchronous, evented I/O.

The "node" way to process a large file (or any file, really) would be to use fs.read() and process each available chunk as it is available from the operating system. However, reading the file as such requires you to do your own (possibly) incremental parsing/processing of the file and some amount of buffering might be inevitable.

SSL first connects to the host, so the host name and port number are transferred as clear text. When the host responds and the challenge succeeds, the client will encrypt the HTTP request with the actual URL (i.e. anything after the third slash) and and send it to the server.

There are several ways to break this security.

It is possible to configure a proxy to act as a "man in the middle". Basically, the browser sends the request to connect to the real server to the proxy. If the proxy is configured this way, it will connect via SSL to the real server but the browser will still talk to the proxy. So if an attacker can gain access of the proxy, he can see all the data that flows through it in clear text.

Your requests will also be visible in the browser history. Users might be tempted to bookmark the site. Some users have bookmark sync tools installed, so the password could end up on deli.ci.us or some other place.

Lastly, someone might have hacked your computer and installed a keyboard logger or a screen scraper (and a lot of Trojan Horse type viruses do). Since the password is visible directly on the screen (as opposed to "*" in a password dialog), this is another security hole.

Conclusion: When it comes to security, always rely on the beaten path. There is just too much that you don't know, won't think of and which will break your neck.

openURL() has been deprecated in iOS 10. Here is the new syntax:

if let url = URL(string: "tel://\(busPhone)") {
    UIApplication.shared.open(url, options: [:], completionHandler: nil)
}

TLDR; Performance-wise Any seems to be slower (if I have set this up properly to evaluate both values at almost same time)

        var list1 = Generate(1000000);
        var forceListEval = list1.SingleOrDefault(o => o == "0123456789012");
        if (forceListEval != "sdsdf")
        {
            var s = string.Empty;
            var start2 = DateTime.Now;
            if (!list1.Exists(o => o == "0123456789012"))
            {
                var end2 = DateTime.Now;
                s += " Exists: " + end2.Subtract(start2);
            }

            var start1 = DateTime.Now;
            if (!list1.Any(o => o == "0123456789012"))
            {
                var end1 = DateTime.Now;
                s +=" Any: " +end1.Subtract(start1);
            }

            if (!s.Contains("sdfsd"))
            {

            }

testing list generator:

private List<string> Generate(int count)
    {
        var list = new List<string>();
        for (int i = 0; i < count; i++)
        {
            list.Add( new string(
            Enumerable.Repeat("ABCDEFGHIJKLMNOPQRSTUVWXYZ", 13)
                .Select(s =>
                {
                    var cryptoResult = new byte[4];
                    new RNGCryptoServiceProvider().GetBytes(cryptoResult);
                    return s[new Random(BitConverter.ToInt32(cryptoResult, 0)).Next(s.Length)];
                })
                .ToArray())); 
        }

        return list;
    }

With 10M records

" Any: 00:00:00.3770377 Exists: 00:00:00.2490249"

With 5M records

" Any: 00:00:00.0940094 Exists: 00:00:00.1420142"

With 1M records

" Any: 00:00:00.0180018 Exists: 00:00:00.0090009"

With 500k, (I also flipped around order in which they get evaluated to see if there is no additional operation associated with whichever runs first.)

" Exists: 00:00:00.0050005 Any: 00:00:00.0100010"

With 100k records

" Exists: 00:00:00.0010001 Any: 00:00:00.0020002"

It would seem Any to be slower by magnitude of 2.

Edit: For 5 and 10M records I changed the way it generates the list and Exists suddenly became slower than Any which implies there's something wrong in the way I am testing.

New testing mechanism:

private static IEnumerable<string> Generate(int count)
    {
        var cripto = new RNGCryptoServiceProvider();
        Func<string> getString = () => new string(
            Enumerable.Repeat("ABCDEFGHIJKLMNOPQRSTUVWXYZ", 13)
                .Select(s =>
                {
                    var cryptoResult = new byte[4];
                    cripto.GetBytes(cryptoResult);
                    return s[new Random(BitConverter.ToInt32(cryptoResult, 0)).Next(s.Length)];
                })
                .ToArray());

        var list = new ConcurrentBag<string>();
        var x = Parallel.For(0, count, o => list.Add(getString()));
        return list;
    }

    private static void Test()
    {
        var list = Generate(10000000);
        var list1 = list.ToList();
        var forceListEval = list1.SingleOrDefault(o => o == "0123456789012");
        if (forceListEval != "sdsdf")
        {
            var s = string.Empty;

            var start1 = DateTime.Now;
            if (!list1.Any(o => o == "0123456789012"))
            {
                var end1 = DateTime.Now;
                s += " Any: " + end1.Subtract(start1);
            }

            var start2 = DateTime.Now;
            if (!list1.Exists(o => o == "0123456789012"))
            {
                var end2 = DateTime.Now;
                s += " Exists: " + end2.Subtract(start2);
            }

            if (!s.Contains("sdfsd"))
            {

            }
        }

Edit2: Ok so to eliminate any influence from generating test data I wrote it all to file and now read it from there.

 private static void Test()
    {
        var list1 = File.ReadAllLines("test.txt").Take(500000).ToList();
        var forceListEval = list1.SingleOrDefault(o => o == "0123456789012");
        if (forceListEval != "sdsdf")
        {
            var s = string.Empty;
            var start1 = DateTime.Now;
            if (!list1.Any(o => o == "0123456789012"))
            {
                var end1 = DateTime.Now;
                s += " Any: " + end1.Subtract(start1);
            }

            var start2 = DateTime.Now;
            if (!list1.Exists(o => o == "0123456789012"))
            {
                var end2 = DateTime.Now;
                s += " Exists: " + end2.Subtract(start2);
            }

            if (!s.Contains("sdfsd"))
            {
            }
        }
    }

10M

" Any: 00:00:00.1640164 Exists: 00:00:00.0750075"

5M

" Any: 00:00:00.0810081 Exists: 00:00:00.0360036"

I think currently the application-context.xml file is into src/main/resources AND the social.properties file is into src/main/java... so when you package (mvn package) or when you run tomcat (mvn tomcat:run) your social.properties disappeared (I know you said when you checked into the .war the files are here... but your exception says the opposite).

The solution is simply to put all your configuration files (application-context.xml and social.properties) into src/main/resources to follow the maven standard structure.

You should also make sure that the ports WAMP uses aren't already in use.

That can be done by typing the following command into the command prompt:

netstat –o

Use a normal blue border, a medium border-radius, and a blue box-shadow with position 0 0.

It sounds trivial, but my issue was that I wasn't in the right project. Make sure you are in the project you expect to be in; otherwise, you won't be able to pull down the correct branches.

You are correct that ** is the power function.

^ is bitwise XOR.

% is indeed the modulus operation, but note that for positive numbers, x % m = x whenever m > x. This follows from the definition of modulus. (Additionally, Python specifies x % m to have the sign of m.)

// is a division operation that returns an integer by discarding the remainder. This is the standard form of division using the / in most programming languages. However, Python 3 changed the behavior of / to perform floating-point division even if the arguments are integers. The // operator was introduced in Python 2.6 and Python 3 to provide an integer-division operator that would behave consistently between Python 2 and Python 3. This means:

| context                                | `/` behavior   | `//` behavior |
---------------------------------------------------------------------------
| floating-point arguments, Python 2 & 3 | float division | int divison   |
---------------------------------------------------------------------------
| integer arguments, python 2            | int division   | int division  |
---------------------------------------------------------------------------
| integer arguments, python 3            | float division | int division  |

For more details, see this question: Division in Python 2.7. and 3.3

Be aware that the result may be slightly different than you expect.

NOW() returns a DATETIME.

And INTERVAL works as named, e.g. INTERVAL 1 DAY = 24 hours.

So if your script is cron'd to run at 03:00, it will miss the first three hours of records from the 'oldest' day.

To get the whole day use CURDATE() - INTERVAL 1 DAY. This will get back to the beginning of the previous day regardless of when the script is run.

the best away now.

this.setState({ myArr: [...this.state.myArr, new_value] })

I did not test the following snippet... hopefully it will point you towards the right direction:

    var jsreader = new JsonTextReader(new StringReader(stringData));
    var json = (JObject)new JsonSerializer().Deserialize(jsreader);
    var tableRows = from p in json["items"]
                 select new
                 {
                     Name = (string)p["Name"],
                     Age = (int)p["Age"],
                     Job = (string)p["Job"]
                 };

Declaring the field as 'final' will ensure that the field is a constant and cannot change. The difference comes in the usage of 'static' keyword.

Declaring a field as static means that it is associated with the type and not with the instances. i.e. only one copy of the field will be present for all the objects and not individual copy for each object. Due to this, the static fields can be accessed through the class name.

As you can see, your requirement that the field should be constant is achieved in both cases (declaring the field as 'final' and as 'static final').

Similar question is private final static attribute vs private final attribute

Queue is an Interface so you can not initiate it directly. Initiate it by one of its implementing classes.

From the docs all known implementing classes:

• AbstractQueue
• ArrayBlockingQueue
• ArrayDeque
• ConcurrentLinkedQueue
• DelayQueue
• LinkedBlockingDeque
• LinkedBlockingQueue
• LinkedList
• PriorityBlockingQueue
• PriorityQueue
• SynchronousQueue

You can use any of above based on your requirement to initiate a Queue object.

I recommend to use moment.js. Only providing date to moment will validate it, no need to pass the dateFormat.

var date = moment("2016-10-19");

And then date.isValid() gives desired result.

This will do:

db.getCollectionNames().forEach(c => {
    db[c].find().forEach(d => {
        print(c); 
        printjson(d)
    })
})

I had a similar issue. You are trying to apply foreign key on a table which has content and the column is not nullable. You have two options.

1. Make the column you want to apply foreign key constraints on to be nullable. That way the foreign key will apply knowing that some fields can be nullable. (This is what i did.)
2. Create the column you want to apply foreign key constraint on, write a query to insert the foreign key into the column and then apply the foreign key constraints. (Did not try this but it should work)

Notice: This is for MySQLdb module in Python.

For a SELECT statement, there shouldn't be an exception for an empty recordset. Just an empty list ([]) for cursor.fetchall() and None for cursor.fetchone().

For any other statement, e.g. INSERT or UPDATE, that doesn't return a recordset, you can neither call fetchall() nor fetchone() on the cursor. Otherwise, an exception will be raised.

There's one way to distinguish between the above two types of cursors:

def yield_data(cursor):
    while True:
        if cursor.description is None:
            # No recordset for INSERT, UPDATE, CREATE, etc
            pass
        else:
            # Recordset for SELECT, yield data
            yield cursor.fetchall()
            # Or yield column names with
            # yield [col[0] for col in cursor.description]

        # Go to the next recordset
        if not cursor.nextset():
            # End of recordsets
            return

Typically a one-line truncate is quite simple

.truncate-text {
  overflow: hidden;
  text-overflow: ellipsis;
  white-space: nowrap;
}

Two line truncate is a little bit more tricky, but it can be done with css this example is in sass.

@mixin multiLineEllipsis($lineHeight: 1.2rem, $lineCount: 2, $bgColor: white, $padding-right: 0.3125rem, $width: 1rem, $ellipsis-right: 0) {
  overflow: hidden; /* hide text if it is more than $lineCount lines  */
  position: relative; /* for set '...' in absolute position */
  line-height: $lineHeight; /* use this value to count block height */
  max-height: $lineHeight * $lineCount; /* max-height = line-height * lines max number */
  padding-right: $padding-right; /* place for '...' */
  white-space: normal; /* overwrite any white-space styles */
  word-break: break-all; /* will break each letter in word */
  text-overflow: ellipsis; /* show ellipsis if text is broken */

  &::before {
    content: '...'; /* create the '...'' points in the end */
    position: absolute;
    right: $ellipsis-right;
    bottom: 0;

Use requests.packages.urllib3.disable_warnings() and verify=False on requests methods.

import requests
from urllib3.exceptions import InsecureRequestWarning

# Suppress only the single warning from urllib3 needed.
requests.packages.urllib3.disable_warnings(category=InsecureRequestWarning)

# Set `verify=False` on `requests.post`.
requests.post(url='https://example.com', data={'bar':'baz'}, verify=False)

Hashtags at the end of the URL bring a visitor to the element with the ID: e.g.

http://stackoverflow.com/questions/8424785/link-to-a-section-of-a-webpage#answers 

Would bring you to where the DIV with the ID 'answers' begins. Also, you can use the name attribute in anchor tags, to create the same effect.

Resource

You can get rid of the first line. You don't need import java.lang.*;

Just change your 5th line to:

public static void main(String [] args) throws Exception

I'll give a slightly advanced answer. In Python, functions are first-class objects. This means they can be "dynamically created, destroyed, passed to a function, returned as a value, and have all the rights as other variables in the programming language have."

Calling a function/class instance in Python means invoking the __call__ method of that object. For old-style classes, class instances are also callable but only if the object which creates them has a __call__ method. The same applies for new-style classes, except there is no notion of "instance" with new-style classes. Rather they are "types" and "objects".

As quoted from the Python 2 Data Model page, for function objects, class instances(old style classes), and class objects(new-style classes), "x(arg1, arg2, ...) is a shorthand for x.__call__(arg1, arg2, ...)".

Thus whenever you define a function with the shorthand def funcname(parameters): you are really just creating an object with a method __call__ and the shorthand for __call__ is to just name the instance and follow it with parentheses containing the arguments to the call. Because functions are first class objects in Python, they can be created on the fly with dynamic parameters (and thus accept dynamic arguments). This comes into handy with decorator functions/classes which you will read about later.

For now I suggest reading the Official Python Tutorial.

Error happens in your function declarations,look the following sentence!You need a semicolon!

AST_NODE* Statement(AST_NODE* node)

You can use a ScheduledExecutorService for this. First you would submit it only once to begin immediately and retain the future that is created. After that you can submit a new task that would cancel the retained future after some period of time.

 ScheduledExecutorService executor = Executors.newScheduledThreadPool(2); 
 final Future handler = executor.submit(new Callable(){ ... });
 executor.schedule(new Runnable(){
     public void run(){
         handler.cancel();
     }      
 }, 10000, TimeUnit.MILLISECONDS);

This will execute your handler (main functionality to be interrupted) for 10 seconds, then will cancel (i.e. interrupt) that specific task.

U can use something like this....

  function (field,value) {

         var newItemOrder= value;
          // Make sure user hasnt already added this item
        angular.forEach(arr, function(item) {
            if (newItemOrder == item.value) {
                arr.splice(arr.pop(item));

            } });

        submitFields.push({"field":field,"value":value});
    };

You just try this, Its so easy

 <script>

  $("#YourDropDownId").change(function () {
            alert($("#YourDropDownId").val());
        });

</script>

The above answer is correct. Works really well. There is also quick way to do this.

1. Open command prompt
   

2. Type - echo export "ANDROID_HOME=/Users/yourName/Library/Android/sdk" >> ~/.bash_profile
   

   Thats's it.
   

3. Close your terminal.
   

4. Open it again.
   

5. Type - echo $ANDROID_HOME to check if the home is set.

Here's another way of doing it:

function isPalin(str) {
  str = str.replace(/\W/g,'').toLowerCase();
  return(str==str.split('').reverse().join(''));
}

you can make that using transform and transform origins.

Combining various transfroms gives similar result. I hope you find it helpful. :) See these examples for simpler transforms. this has left point :

what transform: 0% 50%; does is it sets the origin to vertical middle and horizontal left of the element. so the perspective is not visible at the left part of the image, so it looks flat. Perspective effect is there at the right part, so it looks slanted.

Try : Internet Information Services (IIS) Manager -> Default Web Site -> Click Error Pages properties and select Detail errors

A proper REST API should have below components in response

1. Status Code
2. Response Body
3. Location to the resource which was altered(for example, if a resource was created, client would be interested to know the url of that location)

The main purpose of ResponseEntity was to provide the option 3, rest options could be achieved without ResponseEntity.

So if you want to provide the location of resource then using ResponseEntity would be better else it can be avoided.

Consider an example where a API is modified to provide all the options mentioned

// Step 1 - Without any options provided
@RequestMapping(value="/{id}", method=RequestMethod.GET)
public @ResponseBody Spittle spittleById(@PathVariable long id) {
  return spittleRepository.findOne(id);
}

// Step 2- We need to handle exception scenarios, as step 1 only caters happy path.
@ExceptionHandler(SpittleNotFoundException.class)
@ResponseStatus(HttpStatus.NOT_FOUND)
public Error spittleNotFound(SpittleNotFoundException e) {
  long spittleId = e.getSpittleId();
  return new Error(4, "Spittle [" + spittleId + "] not found");
}

// Step 3 - Now we will alter the service method, **if you want to provide location**
@RequestMapping(
    method=RequestMethod.POST
    consumes="application/json")
public ResponseEntity<Spittle> saveSpittle(
    @RequestBody Spittle spittle,
    UriComponentsBuilder ucb) {

  Spittle spittle = spittleRepository.save(spittle);
  HttpHeaders headers = new HttpHeaders();
  URI locationUri =
  ucb.path("/spittles/")
      .path(String.valueOf(spittle.getId()))
      .build()
      .toUri();
  headers.setLocation(locationUri);
  ResponseEntity<Spittle> responseEntity =
      new ResponseEntity<Spittle>(
          spittle, headers, HttpStatus.CREATED)
  return responseEntity;
}

// Step4 - If you are not interested to provide the url location, you can omit ResponseEntity and go with
@RequestMapping(
    method=RequestMethod.POST
    consumes="application/json")
@ResponseStatus(HttpStatus.CREATED)
public Spittle saveSpittle(@RequestBody Spittle spittle) {
  return spittleRepository.save(spittle);
}

In TextPad:

With the mouse, Left-Click + Alt + Drag. Note that if you first use Alt, and then Click-and-drag, it does not work (at least for me). Ctrl+Alt instead of Alt also Works.

For pure keyboard, no mouse, enable Block Select Mode with Ctrl+Q, B. Or use the sequence Alt, C, B, to do it via the Configure menu.

Warning 1: if Word Wrap is enabled, then Block Select Mode will not be available (which is somewhat logical). First disable Word Wrap. This was causing me some trouble, and this gave me the answer.

Warning 2: if you mean to insert text in every selected row by typing, you have to use Edit, Fill Block. Other editors let you type in directly.

None of these answers worked for me. I had to create my own function called alphanum which stripped the chars for me:

DROP FUNCTION IF EXISTS alphanum; 
DELIMITER | 
CREATE FUNCTION alphanum( str CHAR(255) ) RETURNS CHAR(255) DETERMINISTIC
BEGIN 
  DECLARE i, len SMALLINT DEFAULT 1; 
  DECLARE ret CHAR(255) DEFAULT ''; 
  DECLARE c CHAR(1);
  IF str IS NOT NULL THEN 
    SET len = CHAR_LENGTH( str ); 
    REPEAT 
      BEGIN 
        SET c = MID( str, i, 1 ); 
        IF c REGEXP '[[:alnum:]]' THEN 
          SET ret=CONCAT(ret,c); 
        END IF; 
        SET i = i + 1; 
      END; 
    UNTIL i > len END REPEAT; 
  ELSE
    SET ret='';
  END IF;
  RETURN ret; 
END | 
DELIMITER ; 

Now I can do:

select 'This works finally!', alphanum('This works finally!');

and I get:

+---------------------+---------------------------------+
| This works finally! | alphanum('This works finally!') |
+---------------------+---------------------------------+
| This works finally! | Thisworksfinally                |
+---------------------+---------------------------------+
1 row in set (0.00 sec)

Hurray!

Use

//find first element with "someAttr" attribute
document.querySelector('[someAttr]')

or

//find all elements with "someAttr" attribute
document.querySelectorAll('[someAttr]') 

to find elements by attribute. It's now supported in all relevant browsers (even IE8): http://caniuse.com/#search=queryselector

You can provide options as a parameter to format date. First parameter is for locale which you might not need and second is for options. For more info visit https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleDateString

var date = new Date(Date.UTC(2012, 1, 1, 3, 0, 0));
var options = { year: 'numeric', month: '2-digit', day: '2-digit' };
console.log(date.toLocaleDateString(undefined,options));

I started to write a Script to read OS and browser version that can be tested on Fiddle. Feel free to use and extend.

Since September 2020 the new Edge gets detected. So 'Microsoft Edge' is the new version based on Chromium and the old Edge is now detected as 'Microsoft Legacy Edge'!

First I need to say that your code,

MyClass *myclass;
myclass->DoSomething();

will cause an undefined behavior. Because the pointer "myclass" isn't pointing to any "MyClass" type objects.

Here I have three suggestions for you:-

option 1:- You can simply declare and use a MyClass type object on the stack as below.

MyClass myclass; //allocates memory for the object "myclass", on the stack.
myclass.DoSomething();

option 2:- By using the new operator.

MyClass *myclass = new MyClass();

Three things will hapen here.

i) Allocates memory for the "MyClass" type object on the heap.

ii) Allocates memory for the "MyClass" type pointer "myclass" on the stack.

iii) pointer "myclass" points to the memory address of "MyClass" type object on the heap

Now you can use the pointer to access member functions of the object after dereferencing the pointer by "->"

myclass->DoSomething();

But you should free the memory allocated to "MyClass" type object on the heap, before returning from the scope unless you want it to exists. Otherwise it will cause a memory leak!

delete myclass; // free the memory pointed by the pointer "myclass"

option 3:- you can also do as below.

MyClass myclass; // allocates memory for the "MyClass" type object on the stack.
MyClass *myclassPtr; // allocates memory for the "MyClass" type pointer on the stack.
myclassPtr = &myclass; // "myclassPtr" pointer points to the momory address of myclass object.

Now, pointer and object both are on the stack. Now you can't return this pointer to the outside of the current scope because both allocated memory of the pointer and the object will be freed while stepping outside the scope.

So as a summary, option 1 and 3 will allocate an object on the stack while only the option 2 will do it on the heap.

In Bootstrap 3.3.x make sure you use the scrollspy JavaScript capability to track active elements. It's easy to include it in your HTML. Just do the following:

<body data-spy="scroll" data-target="Id or class of the element you want to track">

In most cases I usually track active elements on my navbar, so I do the following:

<body data-spy="scroll" data-target=".navbar-fixed-top" >

Now in your CSS you can target .navbar-fixed-top .active a:

.navbar-fixed-top .active a { 
    // Put in some styling 
}

This should work if you are tracking active li elements in your top fixed navigation bar.

I found a post suggesting a solution for that. It's about to run:

svn resolve --accept working <YourPath>

which will claim the local version files as OK.
You can run it for single file or entire project catalogues.

You should try console_runner gem. This gem makes your pure Ruby code executable from command-line. All you need is to add YARD annotations to your code:

# @runnable This tool can talk to you. Run it when you are lonely.
#   Written in Ruby.  
class MyClass

    def initialize
      @hello_msg = 'Hello' 
      @bye_msg = 'Good Bye' 
    end

    # @runnable Say 'Hello' to you.
    # @param [String] name Your name
    # @param [Hash] options options
    # @option options [Boolean] :second_meet Have you met before?
    # @option options [String] :prefix Your custom prefix
    def say_hello(name, options = {})
      second_meet = nil
      second_meet = 'Nice to see you again!' if options['second_meet']
      prefix = options['prefix']
      message = @hello_msg + ', '
      message += "#{prefix} " if prefix
      message += "#{name}. "
      message += second_meet if second_meet
      puts message
    end

end

Then run it from console:

$ c_run /projects/example/my_class.rb  say_hello -n John --second-meet --prefix Mr. 
-> Hello, Mr. John. Nice to see you again!

You may be looking for the Git feature called submodules. This feature helps you manage dependent repositories that are nested inside your main repository.

If you are not required to use Apple's look and feel, a simple fix is to put the following code in your application or applet, before you add any GUI components to your JFrame or JApplet:

 try {
    UIManager.setLookAndFeel( UIManager.getCrossPlatformLookAndFeelClassName() );
 } catch (Exception e) {
            e.printStackTrace();
 }

That will set the look and feel to the cross-platform look and feel, and the setBackground() method will then work to change a JButton's background color.

You just need to provide an alias for your aggregate columns in the CTE

d as (SELECT 
   duration, 
   sum(totalitems) as sumtotalitems
FROM 
   [DrySoftBranch].[dbo].[mnthItemWiseTotalQty] ('1') AS BkdQty
group by duration
)

There's many forms of timeout, are you after the connection timeout, request timeout or time to live (time before TCP connection stops).

The default TimeToLive on Firefox is 115s (network.http.keep-alive.timeout)

The default connection timeout on Firefox is 250s (network.http.connection-retry-timeout)

The default request timeout for Firefox is 30s (network.http.pipelining.read-timeout).

The time it takes to do an HttpRequest depends on if a connection has been made this has to be within 250s which I'm guessing you're not after. You're probably after the request timeout which I think is 30,000ms (30s) so to conclude I'd say it's timing out with a connection time out that's why you got a response back after ~150s though I haven't really tested this.

If you have to write static methods in ES5 I found a great tutorial for that:

//Constructor
var Person = function (name, age){
//private properties
var priv = {};

//Public properties
this.name = name;
this.age = age;

//Public methods
this.sayHi = function(){
    alert('hello');
}
}


// A static method; this method only 
// exists on the class and doesn't exist  
// on child objects
Person.sayName = function() {
   alert("I am a Person object ;)");  
};

see @https://abdulapopoola.com/2013/03/30/static-and-instance-methods-in-javascript/

Use stream to write content to webrequest

string data = "username=<value>&password=<value>"; //replace <value>
byte[] dataStream = Encoding.UTF8.GetBytes(data);
private string urlPath = "http://xxx.xxx.xxx/manager/";
string request = urlPath + "index.php/org/get_org_form";
WebRequest webRequest = WebRequest.Create(request);
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.ContentLength = dataStream.Length;  
Stream newStream=webRequest.GetRequestStream();
// Send the data.
newStream.Write(dataStream,0,dataStream.Length);
newStream.Close();
WebResponse webResponse = webRequest.GetResponse();  

Another option, in the host you run rsync from, set the port in the ssh config file, ie:

cat ~/.ssh/config
Host host
    Port 2222

Then rsync over ssh will talk to port 2222:

rsync -rvz --progress --remove-sent-files ./dir user@host:/path

Click on your project properties, go to the web section, from the Servers section, change from IIS express to Local IIS, it will create a virtual directory for you

In case you want to see the local variables of a calling function use select-frame before info locals

E.g.:

(gdb) bt

public class MultiFolderReading {

public void checkNoOfFiles (String filename) throws IOException {

    File dir=new File(filename);
    File files[]=dir.listFiles();//files array stores the list of files

 for(int i=0;i<files.length;i++)
    {
        if(files[i].isFile()) //check whether files[i] is file or directory
        {
            System.out.println("File::"+files[i].getName());

            System.out.println();

If you want it in crlf (Windows Eol), go to File -> Preferences -> Settings. Type "end of line" in the User tab and make sure Files: Eol is set to \r\n and if you're using the Prettier extension, make sure Prettier: End of Line is set to crlf. Finally, on your eslintrc file, add this rule: 'linebreak-style': ['error', 'windows']

On Debian WSL (Windows Subsystem for Linux) I had to use:

sudo chmod -R 775 /var/log/nginx

ArrayList<String> arraylist= new ArrayList<String>();

arraylist.addAll( Arrays.asList("mp3 radio", "presvlake", "dizalica", "sijelice", "brisaci farova", "neonke", "ratkape", "kuka", "trokut")); 

Out of all the available alternatives I found Inkscape to produce the most accurate results when converting PDFs to PNG. Especially when the source file had transparent layers, Inkscape succeeded where Imagemagick and other tools failed.

This is the command I use:

inkscape "$pdf" -z --export-dpi=600 --export-area-drawing --export-png="$pngfile"

And here it is implemented in a script:

#!/bin/bash

while [ $# -gt 0 ]; do

pdf=$1
echo "Converting "$pdf" ..."
pngfile=`echo "$pdf" | sed 's/\.\w*$/.png/'`
inkscape "$pdf" -z --export-dpi=600 --export-area-drawing --export-png="$pngfile"
echo "Converted to "$pngfile""
shift

done

echo "All jobs done. Exiting."

Another base R option could be gl():

gl(5, 3)

Where the output is a factor:

 [1] 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5
Levels: 1 2 3 4 5

If integers are needed, you can convert it:

as.numeric(gl(5, 3))

 [1] 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5

You have to right idea generating the url based off of the input value. The only issue is you are using window.location.href. Setting window.location.href changes the url of the current window. What you probably want to do is change the src attribute of an image.

<html>
<body>
<form>
  <input type="text" value="" id="imagename">
  <input type="button" onclick="var image = document.getElementById('the-image'); image.src='http://webpage.com/images/'+document.getElementById('imagename').value +'.png'" value="GO">
</form>
<img id="the-image">
</body>
</html>

The database.yml is the file where you set up all the information to connect to the database. It differs depending on the kind of DB you use. You can find more information about this in the Rails Guide or any tutorial explaining how to setup a rails project.

The information in the database.yml file is scoped by environment, allowing you to get a different setting for testing, development or production. It is important that you keep those distinct if you don't want the data you use for development deleted by mistake while running your test suite.

Regarding source control, you should not commit this file but instead create a template file for other developers (called database.yml.template). When deploying, the convention is to create this database.yml file in /shared/config directly on the server.

With SVN: svn propset svn:ignore config "database.yml"

With Git: Add config/database.yml to the .gitignore file or with git-extra git ignore config/database.yml

... and now, some examples:

SQLite

adapter: sqlite3
database: db/db_dev_db.sqlite3
pool: 5
timeout: 5000

MYSQL

adapter: mysql
database: my_db
hostname: 127.0.0.1
username: root
password: 
socket: /tmp/mysql.sock
pool: 5
timeout: 5000

MongoDB with MongoID (called mongoid.yml, but basically the same thing)

host: <%= ENV['MONGOID_HOST'] %>
port: <%= ENV['MONGOID_PORT'] %>
username: <%= ENV['MONGOID_USERNAME'] %>
password: <%= ENV['MONGOID_PASSWORD'] %>
database: <%= ENV['MONGOID_DATABASE'] %>
# slaves:
#   - host: slave1.local
#     port: 27018
#   - host: slave2.local
#     port: 27019

You could use JavaScript and trigger the hidden file input when the button input has been clicked.

http://jsfiddle.net/gregorypratt/dhyzV/ - simple

http://jsfiddle.net/gregorypratt/dhyzV/1/ - fancier with a little JQuery

Or, you could style a div directly over the file input and set pointer-events in CSS to none to allow the click events to pass through to the file input that is "behind" the fancy div. This only works in certain browsers though; http://caniuse.com/pointer-events

Just change the version of opencv to 3.4.2.16 .Since it is patented it is not available in newer version.

#include<iostream>
#include<stdlib>
using namespace std;

void main()
{
     char ch;
     int x;
     cin >> ch;
     x = char (ar[1]);
     cout << x;
}

If the starting cell of the range and of the key is static, the solution can be very simple:

Range("A3").Select
Range(Selection, Selection.End(xlToRight)).Select
Range(Selection, Selection.End(xlDown)).Select
Selection.Sort key1:=Range("B3", Range("B3").End(xlDown)), _
order1:=xlAscending, Header:=xlNo

The multi-column index can be used for queries referencing all the columns:

SELECT *
FROM TableName
WHERE Column1=1 AND Column2=2 AND Column3=3

This can be looked up directly using the multi-column index. On the other hand, at most one of the single-column index can be used (it would have to look up all records having Column1=1, and then check Column2 and Column3 in each of those).

There are not a lot of clear answers on this because you are always assuming things.

This solution calculates between two dates the months between assuming you want to save the day of month for comparison, (meaning that the day of the month is considered in the calculation)

Example, if you have a date of 30 Jan 2012, 29 Feb 2012 will not be a month but 01 March 2013 will.

It's been tested pretty thoroughly, probably will clean it up later as we use it, and takes in two dates instead of a Timespan, which is probably better. Hope this helps out anyone else.

private static int TotalMonthDifference(DateTime dtThis, DateTime dtOther)
{
    int intReturn = 0;
    bool sameMonth = false;

    if (dtOther.Date < dtThis.Date) //used for an error catch in program, returns -1
        intReturn--;

    int dayOfMonth = dtThis.Day; //captures the month of day for when it adds a month and doesn't have that many days
    int daysinMonth = 0; //used to caputre how many days are in the month

    while (dtOther.Date > dtThis.Date) //while Other date is still under the other
    {
        dtThis = dtThis.AddMonths(1); //as we loop, we just keep adding a month for testing
        daysinMonth = DateTime.DaysInMonth(dtThis.Year, dtThis.Month); //grabs the days in the current tested month

        if (dtThis.Day != dayOfMonth) //Example 30 Jan 2013 will go to 28 Feb when a month is added, so when it goes to march it will be 28th and not 30th
        {
            if (daysinMonth < dayOfMonth) // uses day in month max if can't set back to day of month
                dtThis.AddDays(daysinMonth - dtThis.Day);
            else
                dtThis.AddDays(dayOfMonth - dtThis.Day);
        }
        if (((dtOther.Year == dtThis.Year) && (dtOther.Month == dtThis.Month))) //If the loop puts it in the same month and year
        {
            if (dtOther.Day >= dayOfMonth) //check to see if it is the same day or later to add one to month
                intReturn++;
            sameMonth = true; //sets this to cancel out of the normal counting of month
        }
        if ((!sameMonth)&&(dtOther.Date > dtThis.Date))//so as long as it didn't reach the same month (or if i started in the same month, one month ahead, add a month)
            intReturn++;
    }
    return intReturn; //return month
}

If the value type is already double, then update the value with $set command can not change the value type double to int when using NumberInt() or NumberLong() function. So, to Change the value type, it must update the whole record.

var re = db.data.find({"name": "zero"})
re['value']=NumberInt(0)
db.data.update({"name": "zero"}, re)

Form isn't included in laravel 5.0 as it was on 4.0, steps to include it:

Begin by installing laravelcollective/html package through Composer. Edit your project's composer.json file to require:

"require": {
    "laravelcollective/html": "~5.0"
}

Next, update composer from the Terminal:

composer update

Next, add your new provider to the providers array of config/app.php:

'providers' => [
  // ...
  'Collective\Html\HtmlServiceProvider',
  // ...
],

Finally, add two class aliases to the aliases array of config/app.php:

'aliases' => [
// ...
  'Form' => 'Collective\Html\FormFacade',
  'Html' => 'Collective\Html\HtmlFacade',
// ...
],

At this point, Form should be working

Source

Update Laravel 5.8 (2019-04-05):

In Laravel 5.8, the providers in the config/app.php can be declared as:

Collective\Html\HtmlServiceProvider::class,

instead of:

'Collective\Html\HtmlServiceProvider',

This notation is the same for the aliases.

Try:

array[i] = Convert.ToDouble(Console.Readline());

You might also want to use double.TryParse() to make sure that the user didn't enter bogus text and handle that somehow.

You can use the this customization to change the default mapping to java.util.Date

<xsd:annotation>
<xsd:appinfo>
    <jaxb:globalBindings>
        <jaxb:javaType name="java.util.Date" xmlType="xsd:dateTime"
                 parseMethod="org.apache.cxf.xjc.runtime.DataTypeAdapter.parseDateTime"
                 printMethod="org.apache.cxf.xjc.runtime.DataTypeAdapter.printDateTime"/>
    </jaxb:globalBindings>
</xsd:appinfo>

Swift 3 with custom title supported

        func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
                return true
            }

    //If you want to change title
            func tableView(_ tableView: UITableView, titleForDeleteConfirmationButtonForRowAt indexPath: IndexPath) -> String? {
                return "Cancel"
            }

            func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
                if (editingStyle == UITableViewCellEditingStyle.delete) {
// you might want to delete the item at the array first before calling this function
                    tableView.deleteRows(at: indexPath, with: .automatic)
                }
            }

You were close. Add this code in the UserForm_Initialize() event handler:

tbxDate.Value = Date

Here is an alternative solution that I found on the matplotlib mailing list:

import matplotlib.pylab as plt

x = range(1000)
ax = plt.axes()
ax.semilogx(x, x)
ax.xaxis.set_ticks_position('none') 

In modern browsers you can do:

.reMode_hover:not(.reMode_selected):hover{}

Consult http://caniuse.com/css-sel3 for compatibility information.

I will add an option to VitalyB's answer:

Option 3

Via npm. If you run your commands via npm, then you could add this setup to your package.json (check out also the webpack.config.js there too). For developing run npm start, no need to copy index.html in this case because the web server will be run from the source files directory, and the bundle.js will be available from the same place (the bundle.js will live in memory only but will available as if it was located together with index.html). For production run npm run build and a dist folder will contain your bundle.js and index.html gets copied with good old cp-command, as you can see below:

"scripts": {
    "test": "NODE_ENV=test karma start",
    "start": "node node_modules/.bin/webpack-dev-server --content-base app",
    "build": "NODE_ENV=production node node_modules/.bin/webpack && cp app/index.html dist/index.html"
  }

Update: Option 4

There is a copy-webpack-plugin, as described in this Stackoverflow answer

But generally, except for the very "first" file (like index.html) and larger assets (like large images or video), include the css, html, images and so on directly in your app via require and webpack will include it for you (well, after you set it up correctly with loaders and possibly plugins).

Windows:

1. in File Win/Users/HOME/.gitconfig set mergetool.keepTemporaries=false
2. in File git/libexec/git-core/git-mergetool, in the function cleanup_temp_files() add rm -rf -- "$MERGED.orig" within the else block.

In Ubuntu if you execute the script with sh scriptname.sh you get this problem.

Try executing the script with ./scriptname.sh instead.

Also look at log4net, which makes logging to 1 or more event stores — whether it's the console, the Windows event log, a text file, a network pipe, a SQL database, etc. — pretty trivial. You can even filter stuff in its configuration, for instance, so that only log records of a particular severity (say ERROR or FATAL) from a single component or assembly are directed to a particular event store.

np.max is just an alias for np.amax. This function only works on a single input array and finds the value of maximum element in that entire array (returning a scalar). Alternatively, it takes an axis argument and will find the maximum value along an axis of the input array (returning a new array).

>>> a = np.array([[0, 1, 6],
                  [2, 4, 1]])
>>> np.max(a)
6
>>> np.max(a, axis=0) # max of each column
array([2, 4, 6])

The default behaviour of np.maximum is to take two arrays and compute their element-wise maximum. Here, 'compatible' means that one array can be broadcast to the other. For example:

>>> b = np.array([3, 6, 1])
>>> c = np.array([4, 2, 9])
>>> np.maximum(b, c)
array([4, 6, 9])

But np.maximum is also a universal function which means that it has other features and methods which come in useful when working with multidimensional arrays. For example you can compute the cumulative maximum over an array (or a particular axis of the array):

>>> d = np.array([2, 0, 3, -4, -2, 7, 9])
>>> np.maximum.accumulate(d)
array([2, 2, 3, 3, 3, 7, 9])

This is not possible with np.max.

You can make np.maximum imitate np.max to a certain extent when using np.maximum.reduce:

>>> np.maximum.reduce(d)
9
>>> np.max(d)
9

Basic testing suggests the two approaches are comparable in performance; and they should be, as np.max() actually calls np.maximum.reduce to do the computation.

Place the image (cancel icon) with position absolute, adjust top and left properties and call method onclick event which clears the input field.

<div class="form-control">
    <input type="text" id="inputField" />
</div>
<span id="iconSpan"><img src="icon.png" onclick="clearInputField()"/></span>

In css position the span accordingly,

#iconSpan {
 position : absolute;
 top:1%;
 left :14%;
}

MD5 encrypting is possible, but decrypting is still unknown (to me). However, there are many ways to compare these things.

1. Using compare methods like so:

   <?php
     $db_pass = $P$BX5675uhhghfhgfhfhfgftut/0;
     $my_pass = "mypass";
     if ($db_pass === md5($my_pass)) {
       // password is matched
     } else {
       // password didn't match
     }
   

2. Only for WordPress users. If you have access to your PHPMyAdmin, focus you have because you paste that hashing here: $P$BX5675uhhghfhgfhfhfgftut/0, WordPress user_pass is not only MD5 format it also uses utf8_mb4_cli charset so what to do?

   That's why I use another Approach if I forget my WordPress password I use

   I install other WordPress with new password :P, and I then go to PHPMyAdmin and copy that hashing from the database and paste that hashing to my current PHPMyAdmin password ( which I forget )

   EASY is use this :

   1. password = "ARJUNsingh@123"
   2. password_hasing = " $P$BDSdKx2nglM.5UErwjQGeVtVWvjEvD1 "
   3. Replace your $P$BX5675uhhghfhgfhfhfgftut/0 with my $P$BDSdKx2nglM.5UErwjQGeVtVWvjEvD1

I USE THIS APPROACH FOR MY SELF WHEN I DESIGN THEMES AND PLUGINS

WORDPRESS USE THIS
