I use this class:

public class JsonContent : StringContent
{
    public JsonContent(object obj) :
        base(JsonConvert.SerializeObject(obj), Encoding.UTF8, "application/json")
    { }
}

Sample of usage:

new HttpClient().PostAsync("http://...", new JsonContent(new { x = 1, y = 2 }));

Display:flex apply flex layout to the flex items or children of the container only. So, the container itself stays a block level element and thus takes up the entire width of the screen.

This causes every flex container to move to a new line on the screen.

Display:inline-flex apply flex layout to the flex items or children as well as to the container itself. As a result the container behaves as an inline flex element just like the children do and thus takes up the width required by its items/children only and not the entire width of the screen.

This causes two or more flex containers one after another, displayed as inline-flex, align themselves side by side on the screen until the whole width of the screen is taken.

If I understand you correctly, you're talking about doing a

svn merge -rn:n-1

to back out of an earlier commit, in which case, you're probably looking for

git revert

I was experiencing the same issue with Cassandra 3.11.0, anytime I changed the address of rpc or listen address cqlsh wouldn't work. I had to add the same local ip to seeds

So after much trial and error my working cassandra.yml ended up like this:

class-name: org.apache.cassandra.locator.SimpleSeedProvider
parameters: 
    -seeds: "192.168.0.30"

listen_adress: 192.168.0.30
rpc_address: 192.168.0.30

public static int countWords(String input) {
        int wordCount = 0;
        boolean isBlankSet = false;
        input = input.trim();

        for (int j = 0; j < input.length(); j++) {
            if (input.charAt(j) == ' ')
                isBlankSet = true;
            else {
                if (isBlankSet) {
                    wordCount++;
                    isBlankSet = false;
                }
            }

        }

        return wordCount + 1;
    }

For this type error: UnexpectedTypeException ERROR: We are trying to use incorrect Hibernate validator annotation on any bean property. For this same issue for my Springboot project( validating type 'java.lang.Integer')

The solution that worked for me is using @NotNull for Integer.

I've always done it with a keypress handler like the above in the past, but today hit on a simpler solution. The enter key just triggers the first non-disabled submit button on the form, so actually all that's required is to intercept that button trying to submit:

<form>
  <div style="display: none;">
    <input type="submit" name="prevent-enter-submit" onclick="return false;">
  </div>
  <!-- rest of your form markup -->
</form>

That's it. Keypresses will be handled as usual by the browser / fields / etc. If the enter-submit logic is triggered, then the browser will find that hidden submit button and trigger it. And the javascript handler will then prevent the submision.

If you are using MySQL installed from HomeBrew in El Capitan, then you should link it as follows:

sudo ln -sf /usr/local/Cellar/mysql/5.6.27/lib/libmysqlclient.18.dylib /usr/local/lib/libmysqlclient.18.dylib

You should be able to do this with a pretty standard DAO recordset loop. You can see some examples at the following links:
http://msdn.microsoft.com/en-us/library/bb243789%28v=office.12%29.aspx
http://www.granite.ab.ca/access/email/recordsetloop.htm

My own standard loop looks something like this:

Dim rs As DAO.Recordset
Set rs = CurrentDb.OpenRecordset("SELECT * FROM Contacts")

'Check to see if the recordset actually contains rows
If Not (rs.EOF And rs.BOF) Then
    rs.MoveFirst 'Unnecessary in this case, but still a good habit
    Do Until rs.EOF = True
        'Perform an edit
        rs.Edit
        rs!VendorYN = True
        rs("VendorYN") = True 'The other way to refer to a field
        rs.Update

        'Save contact name into a variable
        sContactName = rs!FirstName & " " & rs!LastName

        'Move to the next record. Don't ever forget to do this.
        rs.MoveNext
    Loop
Else
    MsgBox "There are no records in the recordset."
End If

MsgBox "Finished looping through records."

rs.Close 'Close the recordset
Set rs = Nothing 'Clean up

Basically, flush() cleans out your RAM buffer, its real power is that it lets you continue to write to it afterwards - but it shouldn't be thought of as the best/safest write to file feature. It's flushing your RAM for more data to come, that is all. If you want to ensure data gets written to file safely then use close() instead.

you can use

ps -ef | grep mysql

Instead of using input type button you can use button and insert the image inside the button content.

<button class="btn btn-default">
     <img src="http://i.stack.imgur.com/e2S63.png" width="20" /> Sign In with Facebook
</button>

To iterate over all the key-value pairs in a table you can use pairs:

for k, v in pairs(arr) do
  print(k, v[1], v[2], v[3])
end

outputs:

pears   2   p   green
apples  0   a   red
oranges 1   o   orange

Edit: Note that Lua doesn't guarantee any iteration order for the associative part of the table. If you want to access the items in a specific order, retrieve the keys from arr and sort it. Then access arr through the sorted keys:

local ordered_keys = {}

for k in pairs(arr) do
    table.insert(ordered_keys, k)
end

table.sort(ordered_keys)
for i = 1, #ordered_keys do
    local k, v = ordered_keys[i], arr[ ordered_keys[i] ]
    print(k, v[1], v[2], v[3])
end

outputs:

  apples  a   red     5
  oranges o   orange  12
  pears   p   green   7

If what you need is that the process should run forever no matter whether you are logged in or not, consider running the process as a daemon.

supervisord is a great out of the box solution that can be used to daemonize any process. It has another controlling utility supervisorctl that can be used to monitor processes that are being run by supervisor.

You don't have to write any extra code or modify existing scripts to make this work. Moreover, verbose documentation makes this process much simpler.

After scratching my head for hours around python-daemon, supervisor is the solution that worked for me in minutes.

Hope this helps someone trying to make python-daemon work

The answers and the documentation provided by MSDN is the best, but I would like to add one typical case that I use a lot which requires the use of #pragma comment to send a command to the linker at link time for example

#pragma comment(linker,"/ENTRY:Entry")

tell the linker to change the entry point form WinMain() to Entry() after that the CRTStartup going to transfer controll to Entry()

For strings you can just after process the string. For docstrings you need to after process the function instead. Here is a solution for both that is still readable.

class Lstrip(object):
    def __rsub__(self, other):
        import re
        return re.sub('^\n', '', re.sub('\n$', '', re.sub('\n\s+', '\n', other)))

msg = '''

The problem with your code is the way the you are using the AsyncTask, because when you rotate the screen during your sleep thread:

Thread.sleep(2000) 

the AsyncTask is still working, it is because you didn't cancel the AsyncTask instance properly in onDestroy() before the fragment rebuilds (when you rotate) and when this same AsyncTask instance (after rotate) runs onPostExecute(), this tries to find the resources with getResources() with the old fragment instance(an invalid instance):

getResources().getString(R.string.app_name)

which is equivalent to:

MyFragment.this.getResources().getString(R.string.app_name)

So the final solution is manage the AsyncTask instance (to cancel if this is still working) before the fragment rebuilds when you rotate the screen, and if canceled during the transition, restart the AsyncTask after reconstruction by the aid of a boolean flag:

public class MyFragment extends SherlockFragment {

    private MyAsyncTask myAsyncTask = null;
    private boolean myAsyncTaskIsRunning = true;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if(savedInstanceState!=null) {
            myAsyncTaskIsRunning = savedInstanceState.getBoolean("myAsyncTaskIsRunning");
        }
        if(myAsyncTaskIsRunning) {
            myAsyncTask = new MyAsyncTask();
            myAsyncTask.execute();
        }
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        outState.putBoolean("myAsyncTaskIsRunning",myAsyncTaskIsRunning);
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        if(myAsyncTask!=null) myAsyncTask.cancel(true);
        myAsyncTask = null;

    }

    public class MyAsyncTask extends AsyncTask<Void, Void, Void>() {

        public MyAsyncTask(){}

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            myAsyncTaskIsRunning = true;
        }
        @Override
        protected Void doInBackground(Void... params) {
            try {
                Thread.sleep(2000);
            } catch (InterruptedException ex) {}
            return null;
        }

        @Override
        protected void onPostExecute(Void result){
            getResources().getString(R.string.app_name);
            myAsyncTaskIsRunning = false;
            myAsyncTask = null;
        }

    }
}

If the above solutions don't work on ubuntu/linux then you can try this

sudo fuser -k -n tcp port

Run it several times to kill processes on your port of choosing. port could be 3000 for example. You would have killed all the processes if you see no output after running the command

This far I've found this one is working, having to set a Timeout of 1ms for the action to complete after chrome's auto-filling ..

$(window).on('load', function() {
    setTimeout(function(){
        $('input[name*=email],input[name*=Password]').val('-').val(null);
    },1);
});

I'm wondering if there's any way of attaching this function to chrome self-completion firing, or even, redeclaring it

The make uses the $ for its own variable expansions. E.g. single character variable $A or variable with a long name - ${VAR} and $(VAR).

To put the $ into a command, use the $$, for example:

all:
  @echo "Please execute next commands:"
  @echo 'setenv PATH /usr/local/greenhills/mips5/linux86:$$PATH'

Also note that to make the "" and '' (double and single quoting) do not play any role and they are passed verbatim to the shell. (Remove the @ sign to see what make sends to shell.) To prevent the shell from expanding $PATH, second line uses the ''.

Here is a simple solution using rsync:

rsync -av -f"+ */" -f"- *" "$source" "$target"

• one line
• no problems with spaces
• preserve permissions

I found this solution there

Of course you can use multiple versions of Java under Windows. And different applications can use different Java versions. How is your application started? Usually you will have a batch file where there is something like

java ...

This will search the Java executable using the PATH variable. So if Java 5 is first on the PATH, you will have problems running a Java 6 application. You should then modify the batch file to use a certain Java version e.g. by defining a environment variable JAVA6HOME with the value C:\java\java6 (if Java 6 is installed in this directory) and change the batch file calling

%JAVA6HOME%\bin\java ...

With .Net Framework 4.5 (using ZipArchive):

using (ZipArchive zip = ZipFile.Open(zipfile, ZipArchiveMode.Read))
    foreach (ZipArchiveEntry entry in zip.Entries)
        if(entry.Name == "myfile")
            entry.ExtractToFile("myfile");

Find "myfile" in zipfile and extract it.

Since the number of columns is a constant, you can just have an List of int[].

    import java.util.*;
    //...

    List<int[]> rowList = new ArrayList<int[]>();

    rowList.add(new int[] { 1, 2, 3 });
    rowList.add(new int[] { 4, 5, 6 });
    rowList.add(new int[] { 7, 8 });

    for (int[] row : rowList) {
        System.out.println("Row = " + Arrays.toString(row));
    } // prints:
      // Row = [1, 2, 3]
      // Row = [4, 5, 6]
      // Row = [7, 8]

    System.out.println(rowList.get(1)[1]); // prints "5"

Since it's backed by a List, the number of rows can grow and shrink dynamically. Each row is backed by an int[], which is static, but you said that the number of columns is fixed, so this is not a problem.

Trying to make some order:

it all works - all but the firefox bookmarking function. for some reason the 'window.sidebar.addPanel' is not a function for the debugger, though it is working fine.

The problem is that it takes its values from the calling <a ..> tag: title as the bookmark name and href as the bookmark address. so this is my code:

javascript:

$("#bookmarkme").click(function () {
  var url = 'http://' + location.host; // i'm in a sub-page and bookmarking the home page
  var name = "Snir's Homepage";

  if (navigator.userAgent.toLowerCase().indexOf('chrome') > -1){ //chrome
    alert("In order to bookmark go to the homepage and press " 
        + (navigator.userAgent.toLowerCase().indexOf('mac') != -1 ? 
            'Command/Cmd' : 'CTRL') + "+D.")
  } 
  else if (window.sidebar) { // Mozilla Firefox Bookmark
    //important for firefox to add bookmarks - remember to check out the checkbox on the popup
    $(this).attr('rel', 'sidebar');
    //set the appropriate attributes
    $(this).attr('href', url);
    $(this).attr('title', name);

    //add bookmark:
    //  window.sidebar.addPanel(name, url, '');
    //  window.sidebar.addPanel(url, name, '');
    window.sidebar.addPanel('', '', '');
  } 
  else if (window.external) { // IE Favorite
        window.external.addFavorite(url, name);
  } 
  return;
});

html:

  <a id="bookmarkme" href="#" title="bookmark this page">Bookmark This Page</a>

In internet explorer there is a different between 'addFavorite': <a href="javascript:window.external.addFavorite('http://tiny.cc/snir','snir-site')">..</a> and 'AddFavorite': <span onclick="window.external.AddFavorite(location.href, document.title);">..</span>.

example here: http://www.yourhtmlsource.com/javascript/addtofavorites.html

Important, in chrome we can't add bookmarks using js (aspnet-i): http://www.codeproject.com/Questions/452899/How-to-add-bookmark-in-Google-Chrome-Opera-and-Saf

Use regular expression to achieve this task. Please refer the below code.

public static void main(String[] args) {
    try {

        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        System.out.print("Enter your content: ");
        String data = reader.readLine();            
        boolean b1 = Pattern.matches("^\\d+$", data);
        boolean b2 = Pattern.matches("[0-9a-zA-Z([+-]?\\d*\\.+\\d*)]*", data); 
        boolean b3 = Pattern.matches("^([+-]?\\d*\\.+\\d*)$", data);
        if(b1) {
            System.out.println("It is integer.");
        } else if(b2) {
            System.out.println("It is String. ");
        } else if(b3) {
            System.out.println("It is Float. ");
        }           
    } catch (IOException ex) {
        Logger.getLogger(TypeOF.class.getName()).log(Level.SEVERE, null, ex);
    }
}

Use this ..

    $str = rawurldecode($_SERVER['REQUEST_URI']);
    $arr = explode("{",$str);
    $arr1 = explode("}", $arr[1]);
    $jsS = '{'.$arr1[0].'}';
    $data = json_decode($jsS,true);

Now ..

use $data['elemname'] to access the values.

send jsonp request with JSON Object.

Request format :

$.ajax({
    method : 'POST',
    url : 'xxx.com',
    data : JSONDataObj, //Use JSON.stringfy before sending data
    dataType: 'jsonp',
    contentType: 'application/json; charset=utf-8',
    success : function(response){
      console.log(response);
    }
}) 

The canonical examples are __declspec(dllimport) and __declspec(dllexport), which instruct the linker to import and export (respectively) a symbol from or to a DLL.

// header
__declspec(dllimport) void foo();


// code - this calls foo() somewhere in a DLL
foo();

(__declspec(..) just wraps up Microsoft's specific stuff - to achieve compatibility, one would usually wrap it away with macros)

No, int in C is not defined to be 32 bits. int and long are not defined to be any specific size at all. The only thing the language guarantees is that sizeof(char)<=sizeof(short)<=sizeof(long).

Theoretically a compiler could make short, char, and long all the same number of bits. I know of some that actually did that for all those types save char.

This is why C now defines types like uint16_t and uint32_t. If you need a specific size, you are supposed to use one of those.

There are the slideDown, slideUp, and slideToggle functions native to jquery 1.3+, and they work quite nicely...

https://api.jquery.com/category/effects/

You can use slideDown just like this:

$("test").slideDown("slow");

And if you want to combine effects and really go nuts I'd take a look at the animate function which allows you to specify a number of CSS properties to shape tween or morph into. Pretty fancy stuff, that.

This can be done by using unlist before as.vector. The result is the same as using the parameter use.names=FALSE.

as.vector(unlist(myList))

In Xcode 11.3.1, the interface has changed from all the current answers.

1. Go to the menu "Xcode" > Preferences > Accounts.
2. Select the proper Apple ID on the left for the project.
3. If the profile is still active, click "Manage Certificates."
4. If there are any revoked certificates, right click the revoked certificate(s) and "Delete Certificate." In the attached screenshot, the certificate boxed in red should be deleted.

Deleting the latest "Date Created" certificate should refresh your certificate, but deleting all the revoked certificates is recommended.

After deleting the revoked certificate(s), you should be able to rebuild the app.

mvn clean package -DpropEnv=PROD

Then using like this in POM.xml

<properties>
    <myproperty>${propEnv}</myproperty>
</properties>

%%%   .
%%% \endtimeline
%%% in between the two, we may have:
%%% \item{date}{description}

%%% the options to timeline are:
%%%      length The amount of vertical space that the timeline should
%%%                use.
%%%      (start,stop) indicate the range of the timeline. All dates or
%%%                sortkeys should lie in the range [start,stop]
%%%
%%% \item without the sort key expects date to be a number (such as a
%%%      year).
%%% \item with the sort key expects the sort key to be a number; date
%%%      can be anything. This can be used for log scale time lines
%%%      or dates that include months or days.
%%% putting \optrule inside of the timeline environment will cause a

I've used python's datetime.data.toordinal to convert dates to 'sort keys' in the context of the package.

I had the same problem, as it did not installed

@angular-devkit/build-angular

The answer which has worked for me was this:

npm i --only=dev

you can covert domain to IP address because every Domain have specific IP address, then you will solve that issue. I hope this will help you.

The question is relatively old, but I hope this post still might be relevant for others.

TL;DR: use AlarmManager to schedule a task, use IntentService, see the sample code here;

What this test-application(and instruction) is about:

Simple helloworld app, which sends you notification every 2 hours. Clicking on notification - opens secondary Activity in the app; deleting notification tracks.

When should you use it:

Once you need to run some task on a scheduled basis. My own case: once a day, I want to fetch new content from server, compose a notification based on the content I got and show it to user.

What to do:

1. First, let's create 2 activities: MainActivity, which starts notification-service and NotificationActivity, which will be started by clicking notification:

   activity_main.xml

   <?xml version="1.0" encoding="utf-8"?>
   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:padding="16dp">
       <Button
           android:id="@+id/sendNotifications"
           android:onClick="onSendNotificationsButtonClick"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:text="Start Sending Notifications Every 2 Hours!" />
   </RelativeLayout>
   

   MainActivity.java

   public class MainActivity extends AppCompatActivity {
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
       }
   
       public void onSendNotificationsButtonClick(View view) {
           NotificationEventReceiver.setupAlarm(getApplicationContext());
       }   
   }
   

   and NotificationActivity is any random activity you can come up with. NB! Don't forget to add both activities into AndroidManifest.

2. Then let's create WakefulBroadcastReceiver broadcast receiver, I called NotificationEventReceiver in code above.

   Here, we'll set up AlarmManager to fire PendingIntent every 2 hours (or with any other frequency), and specify the handled actions for this intent in onReceive() method. In our case - wakefully start IntentService, which we'll specify in the later steps. This IntentService would generate notifications for us.

   Also, this receiver would contain some helper-methods like creating PendintIntents, which we'll use later

   NB1! As I'm using WakefulBroadcastReceiver, I need to add extra-permission into my manifest: <uses-permission android:name="android.permission.WAKE_LOCK" />

   NB2! I use it wakeful version of broadcast receiver, as I want to ensure, that the device does not go back to sleep during my IntentService's operation. In the hello-world it's not that important (we have no long-running operation in our service, but imagine, if you have to fetch some relatively huge files from server during this operation). Read more about Device Awake here.

   NotificationEventReceiver.java

   public class NotificationEventReceiver extends WakefulBroadcastReceiver {
   
       private static final String ACTION_START_NOTIFICATION_SERVICE = "ACTION_START_NOTIFICATION_SERVICE";
       private static final String ACTION_DELETE_NOTIFICATION = "ACTION_DELETE_NOTIFICATION";
       private static final int NOTIFICATIONS_INTERVAL_IN_HOURS = 2;
   
       public static void setupAlarm(Context context) {
           AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
           PendingIntent alarmIntent = getStartPendingIntent(context);
           alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                   getTriggerAt(new Date()),
                   NOTIFICATIONS_INTERVAL_IN_HOURS * AlarmManager.INTERVAL_HOUR,
                   alarmIntent);
       }
   
       @Override
       public void onReceive(Context context, Intent intent) {
           String action = intent.getAction();
           Intent serviceIntent = null;
           if (ACTION_START_NOTIFICATION_SERVICE.equals(action)) {
               Log.i(getClass().getSimpleName(), "onReceive from alarm, starting notification service");
               serviceIntent = NotificationIntentService.createIntentStartNotificationService(context);
           } else if (ACTION_DELETE_NOTIFICATION.equals(action)) {
               Log.i(getClass().getSimpleName(), "onReceive delete notification action, starting notification service to handle delete");
               serviceIntent = NotificationIntentService.createIntentDeleteNotification(context);
           }
   
           if (serviceIntent != null) {
               startWakefulService(context, serviceIntent);
           }
       }
   
       private static long getTriggerAt(Date now) {
           Calendar calendar = Calendar.getInstance();
           calendar.setTime(now);
           //calendar.add(Calendar.HOUR, NOTIFICATIONS_INTERVAL_IN_HOURS);
           return calendar.getTimeInMillis();
       }
   
       private static PendingIntent getStartPendingIntent(Context context) {
           Intent intent = new Intent(context, NotificationEventReceiver.class);
           intent.setAction(ACTION_START_NOTIFICATION_SERVICE);
           return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
       }
   
       public static PendingIntent getDeleteIntent(Context context) {
           Intent intent = new Intent(context, NotificationEventReceiver.class);
           intent.setAction(ACTION_DELETE_NOTIFICATION);
           return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
       }
   }
   

3. Now let's create an IntentService to actually create notifications.

   There, we specify onHandleIntent() which is responses on NotificationEventReceiver's intent we passed in startWakefulService method.

   If it's Delete action - we can log it to our analytics, for example. If it's Start notification intent - then by using NotificationCompat.Builder we're composing new notification and showing it by NotificationManager.notify. While composing notification, we are also setting pending intents for click and remove actions. Fairly Easy.

   NotificationIntentService.java

   public class NotificationIntentService extends IntentService {
   
       private static final int NOTIFICATION_ID = 1;
       private static final String ACTION_START = "ACTION_START";
       private static final String ACTION_DELETE = "ACTION_DELETE";
   
       public NotificationIntentService() {
           super(NotificationIntentService.class.getSimpleName());
       }
   
       public static Intent createIntentStartNotificationService(Context context) {
           Intent intent = new Intent(context, NotificationIntentService.class);
           intent.setAction(ACTION_START);
           return intent;
       }
   
       public static Intent createIntentDeleteNotification(Context context) {
           Intent intent = new Intent(context, NotificationIntentService.class);
           intent.setAction(ACTION_DELETE);
           return intent;
       }
   
       @Override
       protected void onHandleIntent(Intent intent) {
           Log.d(getClass().getSimpleName(), "onHandleIntent, started handling a notification event");
           try {
               String action = intent.getAction();
               if (ACTION_START.equals(action)) {
                   processStartNotification();
               }
               if (ACTION_DELETE.equals(action)) {
                   processDeleteNotification(intent);
               }
           } finally {
               WakefulBroadcastReceiver.completeWakefulIntent(intent);
           }
       }
   
       private void processDeleteNotification(Intent intent) {
           // Log something?
       }
   
       private void processStartNotification() {
           // Do something. For example, fetch fresh data from backend to create a rich notification?
   
           final NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
           builder.setContentTitle("Scheduled Notification")
                   .setAutoCancel(true)
                   .setColor(getResources().getColor(R.color.colorAccent))
                   .setContentText("This notification has been triggered by Notification Service")
                   .setSmallIcon(R.drawable.notification_icon);
   
           PendingIntent pendingIntent = PendingIntent.getActivity(this,
                   NOTIFICATION_ID,
                   new Intent(this, NotificationActivity.class),
                   PendingIntent.FLAG_UPDATE_CURRENT);
           builder.setContentIntent(pendingIntent);
           builder.setDeleteIntent(NotificationEventReceiver.getDeleteIntent(this));
   
           final NotificationManager manager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
           manager.notify(NOTIFICATION_ID, builder.build());
       }
   }
   

4. Almost done. Now I also add broadcast receiver for BOOT_COMPLETED, TIMEZONE_CHANGED, and TIME_SET events to re-setup my AlarmManager, once device has been rebooted or timezone has changed (For example, user flown from USA to Europe and you don't want notification to pop up in the middle of the night, but was sticky to the local time :-) ).

   NotificationServiceStarterReceiver.java

   public final class NotificationServiceStarterReceiver extends BroadcastReceiver {
   
       @Override
       public void onReceive(Context context, Intent intent) {
           NotificationEventReceiver.setupAlarm(context);
       }
   }
   

5. We need to also register all our services, broadcast receivers in AndroidManifest:

   <?xml version="1.0" encoding="utf-8"?>
   <manifest xmlns:android="http://schemas.android.com/apk/res/android"
       package="klogi.com.notificationbyschedule">
   
       <uses-permission android:name="android.permission.INTERNET" />
       <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
       <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
       <uses-permission android:name="android.permission.WAKE_LOCK" />
   
       <application
           android:allowBackup="true"
           android:icon="@mipmap/ic_launcher"
           android:label="@string/app_name"
           android:supportsRtl="true"
           android:theme="@style/AppTheme">
           <activity android:name=".MainActivity">
               <intent-filter>
                   <action android:name="android.intent.action.MAIN" />
   
                   <category android:name="android.intent.category.LAUNCHER" />
               </intent-filter>
           </activity>
   
           <service
               android:name=".notifications.NotificationIntentService"
               android:enabled="true"
               android:exported="false" />
   
           <receiver android:name=".broadcast_receivers.NotificationEventReceiver" />
           <receiver android:name=".broadcast_receivers.NotificationServiceStarterReceiver">
               <intent-filter>
                   <action android:name="android.intent.action.BOOT_COMPLETED" />
                   <action android:name="android.intent.action.TIMEZONE_CHANGED" />
                   <action android:name="android.intent.action.TIME_SET" />
               </intent-filter>
           </receiver>
   
           <activity
               android:name=".NotificationActivity"
               android:label="@string/title_activity_notification"
               android:theme="@style/AppTheme.NoActionBar"/>
       </application>
   
   </manifest>
   

That's it!

The source code for this project you can find here. I hope, you will find this post helpful.

I'm using XAMPP, in which there are several php.ini files.

You can find the line in the php.ini files: ;extension=php_curl.dll

Please remove ; at the beginning of this line. And you may need to restart apache server.

If dt is your datetime column, then

For 1:

SUBSTRING(CONVERT(varchar, dt, 13), 1, 2)
    + UPPER(SUBSTRING(CONVERT(varchar, dt, 13), 4, 3))

For 2:

SUBSTRING(CONVERT(varchar, dt, 100), 13, 2)
    + SUBSTRING(CONVERT(varchar, dt, 100), 16, 3)

By wrapping your comparisons in {} in your first example you are creating ScriptBlocks; so the PowerShell interpreter views it as Where-Object { <ScriptBlock> -and <ScriptBlock> }. Since the -and operator operates on boolean values, PowerShell casts the ScriptBlocks to boolean values. In PowerShell anything that is not empty, zero or null is true. The statement then looks like Where-Object { $true -and $true } which is always true.

Instead of using {}, use parentheses ().

Also you want to use -eq instead of -match since match uses regex and will be true if the pattern is found anywhere in the string (try: 'xlsx' -match 'xls').

Invoke-Command -computername SERVERNAME { 
    Get-ChildItem -path E:\dfsroots\datastore2\public | 
        Where-Object {($_.extension -eq ".xls" -or $_.extension -eq ".xlk") -and ($_.creationtime -ge "06/01/2014")}
}

A better option is to filter the extensions at the Get-ChildItem command.

Invoke-Command -computername SERVERNAME { 
    Get-ChildItem -path E:\dfsroots\datastore2\public\* -Include *.xls, *.xlk | 
        Where-Object {$_.creationtime -ge "06/01/2014"}
}

To save the Log cat content to the file, you need to redirect to the android sdk's platform tools folder and hit the below command

adb logcat > logcat.txt

In Android Studio, version 3.6RC1, file will be created of the name "logcat.txt" in respective project folder. you can change the name according to your interest. enjoy

You can't cast a base object to a derived type - it isn't of that type.

If you have a base type pointer to a derived object, then you can cast that pointer around using dynamic_cast. For instance:

DerivedType D;
BaseType B;

BaseType *B_ptr=&B
BaseType *D_ptr=&D;// get a base pointer to derived type

DerivedType *derived_ptr1=dynamic_cast<DerivedType*>(D_ptr);// works fine
DerivedType *derived_ptr2=dynamic_cast<DerivedType*>(B_ptr);// returns NULL

$("#YourElementID").css("display","block");

Edit: or as dave thieben points out in his comment below, you can do this as well:

$("#YourElementID").css({ display: "block" });

With the two previous steps stated above, you're still missing the foreign key constraint. This should work:

  class AddUserReferenceToTester < ActiveRecord::Migration
      def change
          add_column :testers, :user_id, :integer, references: :users
      end
  end

Well Suragch gave the best answer so far but he skipped certain minor stuff that was important to getting the app compiled.

I hope to make a better answer than Suragch by improving on his answer. I will add all the missing elements he didnt put.

I compiled my apk using the android app , APK Builder 1.1.0. So let's begin.

To build an Android app we need couple files and folders that are organized in a certain format and capitalized accordingly.

res layout -> xml files depicting how app will look on phone. Similar to how html shapes how web page looks on browser. Allowing your app to fit on screens accordingly.

values -> constant data such as colors.xml, strings.xml, styles.xml. These files must be properly spelt.

drawable -> pics{jpeg, png,...}; Name them anything.

mipmap -> more pics. used for app icon?

xml -> more xml files.

src -> acts like JavaScript in html. layout files will initiate the starting view and your java file will dynamically control the tag elements and trigger events. Events can also be activated directly in the layout.xml just like in html.

AndroidManifest.xml -> This file registers what your app is about. Application name, Type of program, permissions needed, etc. This seems to make Android rather safe. Programs literally cannot do what they didnt ask for in the Manifest.

Now there are 4 types of Android programs, an activity, a service, a content provider, and a broadcast reciever. Our keyboard will be a service, which allows it to run in the background. It will not appear in the list of apps to launch; but it can be uninstalled.

To compile your app, involves gradle, and apk signing. You can research that one or use APK Builder for android. It is super easy.

Now that we understand Android development, let us create the files and folders.

1. Create the files and folders as I discussed above. My directory wil look as follows:

   • NumPad
     • AndroidManifest.xml
     • src
       • Saragch
         • num_pad
           • MyInputMethodService.java
     • res
       • drawable
         • Suragch_NumPad_icon.png
       • layout
         • key_preview.xml
         • keyboard_view.xml
       • xml
         • method.xml
         • number_pad.xml
       • values
         • colors.xml
         • strings.xml
         • styles.xml

Remember if you are using an ide such as Android Studio it may have a project file.

2. Write files.

A: NumPad/res/layout/key_preview.xml

<?xml version="1.0" encoding="utf-8"?>
   <TextView
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:gravity="center"
      android:background="@android:color/white"
      android:textColor="@android:color/black"
      android:textSize="30sp">
</TextView>

B: NumPad/res/layout/keyboard_view.xml

<?xml version="1.0" encoding="utf-8"?>
<android.inputmethodservice.KeyboardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/keyboard_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:keyPreviewLayout="@layout/key_preview"
    android:layout_alignParentBottom="true">

</android.inputmethodservice.KeyboardView>

C: NumPad/res/xml/method.xml

<?xml version="1.0" encoding="utf-8"?>
<input-method  xmlns:android="http://schemas.android.com/apk/res/android">
    <subtype  android:imeSubtypeMode="keyboard"/>
</input-method>

D: Numpad/res/xml/number_pad.xml

<?xml version="1.0" encoding="utf-8"?>
<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"
    android:keyWidth="20%p"
    android:horizontalGap="5dp"
    android:verticalGap="5dp"
    android:keyHeight="60dp">

    <Row>
        <Key android:codes="49" android:keyLabel="1" android:keyEdgeFlags="left"/>
        <Key android:codes="50" android:keyLabel="2"/>
        <Key android:codes="51" android:keyLabel="3"/>
        <Key android:codes="52" android:keyLabel="4"/>
        <Key android:codes="53" android:keyLabel="5" android:keyEdgeFlags="right"/>
    </Row>

    <Row>
        <Key android:codes="54" android:keyLabel="6" android:keyEdgeFlags="left"/>
        <Key android:codes="55" android:keyLabel="7"/>
        <Key android:codes="56" android:keyLabel="8"/>
        <Key android:codes="57" android:keyLabel="9"/>
        <Key android:codes="48" android:keyLabel="0" android:keyEdgeFlags="right"/>
    </Row>

    <Row>
        <Key android:codes="-5"
             android:keyLabel="DELETE"
             android:keyWidth="40%p"
             android:keyEdgeFlags="left"
             android:isRepeatable="true"/>
        <Key android:codes="10"
             android:keyLabel="ENTER"
             android:keyWidth="60%p"
             android:keyEdgeFlags="right"/>
    </Row>

</Keyboard>

Of course this can be easily edited to your liking. You can even use images instead lf words for the label.

Suragch didnt demonstrate the files in the values folder and assumed we had access to Android Studio; which automatically creates them. Good thing I have APK Builder.

E: NumPad/res/values/colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">#3F51B5</color>
    <color name="colorPrimaryDark">#303F9F</color>
    <color name="colorAccent">#FF4081</color>
</resources>

F: NumPad/res/values/strings.xml

<resources>
    <string name="app_name">Suragch NumPad</string>
</resources>

G: NumPad/res/values/styles.xml

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="android:Theme.Material.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>

</resources>

H: Numpad/AndroidManifest.xml

This is the file that was really up for contension. Here I felt I would never compile my program. sob. sob. If you check Suracgh's answer you see he leaves the first set of fields empty, and adds the activity tag in this file. As I said there are four types of Android programs. An activity is a regular app with a launcher icon. This numpad is not an activity! Further he didnt implement any activity.

My friends do not include the activity tag. Your program will compile, and when you try to launch it will crash! As for xmlns:android and uses-sdk; I cant help you there. Just try my settings if they work.

As you can see there is a service tag, which register it as a service. Also service.android:name must be name of public class extending service in our java file. It MUST be capitalized accordingly. Also package is the name of the package we declared in java file.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="Saragch.num_pad">

    <uses-sdk

I: NumPad/src/Saragch/num_pad/MyInputMethodService.java

Note: I think java is an alternative to src.

This was another problem file but not as contentious as the manifest file. As I know Java good enough to know what is what, what is not. I barely know xml and how it ties in with Android development!

The problem here was he didnt import anything! I mean, he gave us a "complete" file which uses names that couldnt be resolved! InputMethodService, Keyboard, etc. That is bad practice Mr. Suragch. Thanks for helping me out but how did you expect the code to compile if the names cant be resolved?

Following is the correctly edited version. I just happened to pounce upon couple hints to drove me to the right place to learn what exactly to import.

package Saragch.num_pad;

import android.inputmethodservice.InputMethodService;
import android.inputmethodservice.KeyboardView;
import android.inputmethodservice.Keyboard;

import android.text.TextUtils;
import android.view.inputmethod.InputConnection;

import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.os.Build;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;


public class MyInputMethodService extends InputMethodService implements KeyboardView.OnKeyboardActionListener 
{
    @Override
    public View onCreateInputView() 
    {
     // get the KeyboardView and add our Keyboard layout to it
     KeyboardView keyboardView = (KeyboardView)getLayoutInflater().inflate(R.layout.keyboard_view, null);
     Keyboard keyboard = new Keyboard(this, R.xml.number_pad);
     keyboardView.setKeyboard(keyboard);
     keyboardView.setOnKeyboardActionListener(this);
     return keyboardView;
    }

    @Override
    public void onKey(int primaryCode, int[] keyCodes) 
    {

        InputConnection ic = getCurrentInputConnection();

        if (ic == null) return;

        switch (primaryCode)
        {
         case Keyboard.KEYCODE_DELETE:
            CharSequence selectedText = ic.getSelectedText(0);

            if (TextUtils.isEmpty(selectedText)) 
            {
             // no selection, so delete previous character
             ic.deleteSurroundingText(1, 0);
            }

            else 
            {
             // delete the selection
             ic.commitText("", 1);
            }

            ic.deleteSurroundingText(1, 0);
            break;

         default:
            char code = (char) primaryCode;
            ic.commitText(String.valueOf(code), 1);
        }
    }

    @Override
    public void onPress(int primaryCode) { }

    @Override
    public void onRelease(int primaryCode) { }

    @Override
    public void onText(CharSequence text) { }

    @Override
    public void swipeLeft() { }

    @Override
    public void swipeRight() { }

    @Override
    public void swipeDown() { }

    @Override
    public void swipeUp() { }
}

3. Compile and sign your project.

   This is where I am clueless as a newby Android developer. I would like to learn it manually, as I believe real programmers can compile manually.

I think gradle is one of the tools for compiling and packaging to apk. apk seems to be like a jar file or a rar for zip file. There are then two types of signing. debug key which is not alllowed on play store and private key.

Well lets give Mr. Saragch a hand. And thank you for watching my video. Like, subscribe.

Perhaps the following, then your calculator can use arbitrary number base (e.g. hex, binary, base 7! etc): (untested)

def convert(str):
    try:
        base = 10  # default
        if ':' in str:
            sstr = str.split(':')
            base, str = int(sstr[0]), sstr[1]
        val = int(str, base)
    except ValueError:
        val = None

    return val

val = convert(raw_input("Enter value:"))
# 10     : Decimal
# 16:a   : Hex, 10
# 2:1010 : Binary, 10

The Swift way is to use the global split function, like so:

var fullName = "First Last"
var fullNameArr = split(fullName) {$0 == " "}
var firstName: String = fullNameArr[0]
var lastName: String? = fullNameArr.count > 1 ? fullNameArr[1] : nil

with Swift 2

In Swift 2 the use of split becomes a bit more complicated due to the introduction of the internal CharacterView type. This means that String no longer adopts the SequenceType or CollectionType protocols and you must instead use the .characters property to access a CharacterView type representation of a String instance. (Note: CharacterView does adopt SequenceType and CollectionType protocols).

let fullName = "First Last"
let fullNameArr = fullName.characters.split{$0 == " "}.map(String.init)
// or simply:
// let fullNameArr = fullName.characters.split{" "}.map(String.init)

fullNameArr[0] // First
fullNameArr[1] // Last 

$s = "my name is ";

$s .= "keyur";

echo $s; 

result:

my name is keyur

Try

padding : 10px 10px 10px 10px;

I wrote a batch script a while ago that allows you to pick a file extension to delete. The script will look in the folder it is in and all subfolders for any file with that extension and delete it.

@ECHO OFF
CLS

SET found=0
ECHO Enter the file extension you want to delete...
SET /p ext="> "

IF EXIST *.%ext% (           rem Check if there are any in the current folder :)
  DEL *.%ext%
  SET found=1
)
FOR /D /R %%G IN ("*") DO (  rem Iterate through all subfolders
  IF EXIST %%G CD %%G
  IF EXIST *.%ext% (
    DEL *.%ext%
    SET found=1
  )
)

IF %found%==1 (
  ECHO.
  ECHO Deleted all .%ext% files.
  ECHO.
) ELSE (
  ECHO.
  ECHO There were no .%ext% files.
  ECHO Nothing has been deleted.
  ECHO.
)

PAUSE
EXIT

Hope this comes in useful to anyone who wants it :)

In WPF, TextBox element will not get opportunity to use "Enter" button for creating KeyUp Event until you will not set property: AcceptsReturn="True".

But, it would`t solve the problem with handling KeyUp Event in TextBox element. After pressing "ENTER" you will get a new text line in TextBox.

I had solved problem of using KeyUp Event of TextBox element by using Bubble event strategy. It's short and easy. You have to attach a KeyUp Event handler in some (any) parent element:

XAML:

<Window x:Class="TextBox_EnterButtomEvent.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:TextBox_EnterButtomEvent"
    mc:Ignorable="d"
    Title="MainWindow" Height="350" Width="525">
<Grid KeyUp="Grid_KeyUp">
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height ="0.3*"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
    <TextBlock Grid.Row="1" Grid.Column="1" Padding="0" TextWrapping="WrapWithOverflow">
        Input text end press ENTER:
    </TextBlock>
    <TextBox Grid.Row="2" Grid.Column="1" HorizontalAlignment="Stretch"/>
    <TextBlock Grid.Row="4" Grid.Column="1" Padding="0" TextWrapping="WrapWithOverflow">
        You have entered:
    </TextBlock>
    <TextBlock Name="txtBlock" Grid.Row="5" Grid.Column="1" HorizontalAlignment="Stretch"/>
</Grid></Window>

C# logical part (KeyUp Event handler is attached to a grid element):

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void Grid_KeyUp(object sender, KeyEventArgs e)
    {
        if(e.Key == Key.Enter)
        {
            TextBox txtBox = e.Source as TextBox;
            if(txtBox != null)
            {
                this.txtBlock.Text = txtBox.Text;
                this.txtBlock.Background = new SolidColorBrush(Colors.LightGray);
            }
        }
    }
}

Result:

Thanks, Bendin. I like your solution very much.

I changed it to work in reverse order, showing most recent changes first. Which is important with long standing code, maintained over several years. I usually pipe it into more.

I added -r to the sort. I removed spec. handling for 'first record'. It is it will error out on the last entry, as there is nothing to diff it with. Though I am living with it because I never get down that far.

To multiply, use mult for signed multiplication and multu for unsigned multiplication. Note that the result of the multiplication of two 32-bit numbers yields a 64-number. If you want the result back in $v0 that means that you assume the result will fit in 32 bits.

The 32 most significant bits will be held in the HI special register (accessible by mfhi instruction) and the 32 least significant bits will be held in the LO special register (accessible by the mflo instruction):

E.g.:

li $a0, 5
li $a1, 3
mult $a0, $a1
mfhi $a2 # 32 most significant bits of multiplication to $a2
mflo $v0 # 32 least significant bits of multiplication to $v0

To divide, use div for signed division and divu for unsigned division. In this case, the HI special register will hold the remainder and the LO special register will hold the quotient of the division.

E.g.:

div $a0, $a1
mfhi $a2 # remainder to $a2
mflo $v0 # quotient to $v0

I use the same method suggested by chalup,

ParentDirectory = <your directory>

RCC_DIR = "$$ParentDirectory\Build\RCCFiles"
UI_DIR = "$$ParentDirectory\Build\UICFiles"
MOC_DIR = "$$ParentDirectory\Build\MOCFiles"
OBJECTS_DIR = "$$ParentDirectory\Build\ObjFiles"

CONFIG(debug, debug|release) { 
    DESTDIR = "$$ParentDirectory\debug"
}
CONFIG(release, debug|release) { 
    DESTDIR = "$$ParentDirectory\release"
}

This is an example without the new C++ interface (works for 90, 180 and 270 degrees, using param = 1, 2 and 3). Remember to call cvReleaseImage on the returned image after using it.

IplImage *rotate_image(IplImage *image, int _90_degrees_steps_anti_clockwise)
{
    IplImage *rotated;

    if(_90_degrees_steps_anti_clockwise != 2)
        rotated = cvCreateImage(cvSize(image->height, image->width), image->depth, image->nChannels);
    else
        rotated = cvCloneImage(image);

    if(_90_degrees_steps_anti_clockwise != 2)
        cvTranspose(image, rotated);

    if(_90_degrees_steps_anti_clockwise == 3)
        cvFlip(rotated, NULL, 1);
    else if(_90_degrees_steps_anti_clockwise == 1)
        cvFlip(rotated, NULL, 0);
    else if(_90_degrees_steps_anti_clockwise == 2)
        cvFlip(rotated, NULL, -1);

    return rotated;
}

It can be done using SQL Server Import and Export Wizard. But if you're familiar with SSIS and don't want to run the SQL Server Import and Export Wizard, create an SSIS package that uses the Excel Source and the SQL Server Destination in the data flow.

You cannot use primitive types in HashMap. int, or double don't work. You have to use its enclosing type. for an example

Map<String,Integer> m = new HashMap<String,Integer>();

Now both are objects, so this will work.

IANA has registered the official MIME Type for JSON as application/json.

When asked about why not text/json, Crockford seems to have said JSON is not really JavaScript nor text and also IANA was more likely to hand out application/* than text/*.

I want to change the width and height of a div. data attributes did not change it. Instead I use:

var size = $("#theme_photo_size").val().split("x");
$("#imageupload_img").width(size[0]);
$("#imageupload_img").attr("data-width", size[0]);
$("#imageupload_img").height(size[1]);
$("#imageupload_img").attr("data-height", size[1]);

be careful:

$("#imageupload_img").data("height", size[1]); //did not work

did not set it

$("#imageupload_img").attr("data-height", size[1]); // yes it worked!

this has set it.

lista = list.sort(lista)

This should be

lista.sort()

The .sort() method is in-place, and returns None. If you want something not in-place, which returns a value, you could use

sorted_list = sorted(lista)

Aside #1: please don't call your lists list. That clobbers the builtin list type.

Aside #2: I'm not sure what this line is meant to do:

print str("value 1a")+str(" + ")+str("value 2")+str(" = ")+str("value 3a ")+str("value 4")+str("\n")

is it simply

print "value 1a + value 2 = value 3a value 4"

? In other words, I don't know why you're calling str on things which are already str.

Aside #3: sometimes you use print("something") (Python 3 syntax) and sometimes you use print "something" (Python 2). The latter would give you a SyntaxError in py3, so you must be running 2.*, in which case you probably don't want to get in the habit or you'll wind up printing tuples, with extra parentheses. I admit that it'll work well enough here, because if there's only one element in the parentheses it's not interpreted as a tuple, but it looks strange to the pythonic eye..

The exception TypeError: 'NoneType' object is not subscriptable happens because the value of lista is actually None. You can reproduce TypeError that you get in your code if you try this at the Python command line:

None[0]

The reason that lista gets set to None is because the return value of list.sort() is None... it does not return a sorted copy of the original list. Instead, as the documentation points out, the list gets sorted in-place instead of a copy being made (this is for efficiency reasons).

If you do not want to alter the original version you can use

other_list = sorted(lista)

Cursor might used for retrieving data row by row basis.its act like a looping statement(ie while or for loop). To use cursors in SQL procedures, you need to do the following: 1.Declare a cursor that defines a result set. 2.Open the cursor to establish the result set. 3.Fetch the data into local variables as needed from the cursor, one row at a time. 4.Close the cursor when done.

for ex:

declare @tab table
(
Game varchar(15),
Rollno varchar(15)
)
insert into @tab values('Cricket','R11')
insert into @tab values('VollyBall','R12')

declare @game  varchar(20)
declare @Rollno varchar(20)

declare cur2 cursor for select game,rollno from @tab 

open cur2

fetch next from cur2 into @game,@rollno

WHILE   @@FETCH_STATUS = 0   
begin

print @game

print @rollno

FETCH NEXT FROM cur2 into @game,@rollno

end

close cur2

deallocate cur2

More readable way:

class A {
  void foo() throws MyException() {
    ...
  }
}

Just hide it in a RuntimeException to get it past forEach()

  void bar() throws MyException {
      Stream<A> as = ...
      try {
          as.forEach(a -> {
              try {
                  a.foo();
              } catch(MyException e) {
                  throw new RuntimeException(e);
              }
          });
      } catch(RuntimeException e) {
          throw (MyException) e.getCause();
      }
  }

Although at this point I won't hold against someone if they say skip the streams and go with a for loop, unless:

• you're not creating your stream using Collection.stream(), i.e. not straight forward translation to a for loop.
• you're trying to use parallelstream()

I found dfsq's answer its comments extremely useful. I made some minor modifications applicable to me (and I'm posting it here, in case it is of some use to others).

1. Using class as hooks, instead of table elements tr
2. Searching/comparing text within a child class while showing/hiding parent
3. Making it more efficient by storing the $rows text elements into an array only once (and avoiding $rows.length times computation)

var $rows = $('.wrapper');
var rowsTextArray = [];

var i = 0;
$.each($rows, function () {
    rowsTextArray[i] = ($(this).find('.number').text() + $(this).find('.fruit').text())
        .replace(/\s+/g, '')
        .toLowerCase();
    i++;
});

$('#search').keyup(function() {
  var val = $.trim($(this).val()).replace(/\s+/g, '').toLowerCase();
  $rows.show().filter(function(index) {
    return (rowsTextArray[index].indexOf(val) === -1);
  }).hide();
});

span {
  margin-right: 0.2em;
}

<input type="text" id="search" placeholder="type to search" />

<div class="wrapper"><span class="number">one</span><span class="fruit">apple</span></div>

It facilitates importing other python files. When you placed this file in a directory (say stuff)containing other py files, then you can do something like import stuff.other.

root\
    stuff\
         other.py

    morestuff\
         another.py

Without this __init__.py inside the directory stuff, you couldn't import other.py, because Python doesn't know where the source code for stuff is and unable to recognize it as a package.

The tibble vignette has an updated way to change its default printing behavior:

You can control the default appearance with options:

options(tibble.print_max = n, tibble.print_min = m): if there are more than n rows, print only the first m rows. Use options(tibble.print_max = Inf) to always show all rows.

options(tibble.width = Inf) will always print all columns, regardless of the width of the screen.

examples

This will always print all rows:

options(tibble.print_max = Inf)

This will not actually limit the printing to 50 lines:

options(tibble.print_max = 50)

But this will restrict printing to 50 lines:

options(tibble.print_max = 50, tibble.print_min = 50)

Setting the HttpWebRequest.KeepAlive to false didn't work for me.

Since I was accessing a HTTPS page I had to set the Service Point Security Protocol to Tls12.

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Notice that there are other SecurityProtocolTypes: SecurityProtocolType.Ssl3, SecurityProtocolType.Tls, SecurityProtocolType.Tls11

So if the Tls12 doesn't work for you, try the three remaining options.

Also notice that you can set multiple protocols. This is preferable on most cases.

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;

Edit: Since this is a choice of security standards it's obviously best to go with the latest (TLS 1.2 as of writing this), and not just doing what works. In fact, SSL3 has been officially prohibited from use since 2015 and TLS 1.0 and TLS 1.1 will likely be prohibited soon as well. source: @aske-b

Finally I decided to use ls, and bash array expansion:

TEMP=( $( ls -ln FILE ) )
SIZE=${TEMP[4]}

it's not really nice, but at least it does only 1 fork+execve, and it doesn't rely on secondary programming language (perl/ruby/python/whatever)

For ASP.NET MVC, we successfully save a form with checkboxes via an AJAX POST with the following, which is a combination of several methods referenced in this post, including @Jecoms suggestion:

var form = $('#myForm');
// Serialize the form into a JavaScript object using the jQuery.serializeObject plugin
// https://plugins.jquery.com/serializeObject/
var data = form.serializeObject();
// Change the submitted value of checkboxes to the value of the checked property
$('#myForm input[type=checkbox]').each( function () { data[this.name] = this.checked; } );
// For a MVC controller, convert the JS object back into a query string using jQuery.param function
data = $.param(data);
// Perform AJAX POST with the form data
$.ajax({
    async: true,
    url: 'mvcActionMethodURL',
    type: 'POST',
    data: data,
    success: function (data, textStatus, xhr) {

    },
    error: function (xhr, status, error) {

    }
});

I guess it's a matter of taste, although (mistakenly) mixing them up might cause some undesired behaviors:

true && false || false; // returns false

true and false || false; // returns true

Hence, using && and || is safer for they have the highest precedence. In what regards to readability, I'd say these operators are universal enough.

UPDATE: About the comments saying that both operations return false ... well, in fact the code above does not return anything, I'm sorry for the ambiguity. To clarify: the behavior in the second case depends on how the result of the operation is used. Observe how the precedence of operators comes into play here:

var_dump(true and false || false); // bool(false)

$a = true and false || false; var_dump($a); // bool(true)

The reason why $a === true is because the assignment operator has precedence over any logical operator, as already very well explained in other answers.

I had a user control which sat on page in a free form way, not constrained by another container, and the contents within the user control would not auto size but expand to the full size of what the user control was handed.

To get the user control to simply size to its content, for height only, I placed it into a grid with on row set to auto size such as this:

<Grid Margin="0,60,10,200">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
    </Grid.RowDefinitions>
    <controls1:HelpPanel x:Name="HelpInfoPanel"
                         Visibility="Visible"
                         Width="570"
                         HorizontalAlignment="Right"
                         ItemsSource="{Binding HelpItems}"
                         Background="#FF313131" />
</Grid>

I would try to call

spinner.setOnItemSelectedListener(new MyOnItemSelectedListener());

after you call setAdapter(). Also try out calling before the adapter.

You always have the solution to go with subclassing, where you can wrap a boolean flag to your overriden setAdapter method to skip the event.

Edited: Kindly note that
whereBetween('date',$start_date,$end_date)
is inclusive of the first date.

This below command worked for me

Python version - 2.7

package - python-jenkins

command - $ pip install 'python-jenkins>=1.1.1'

I've been looking for a solution to this using the newest driver for C# 3.6 and here's the fix I eventually settled on. The key here is using "$[]" which according to MongoDB is new as of version 3.6. See https://docs.mongodb.com/manual/reference/operator/update/positional-all/#up.S[] for more information.

Here's the code:

{
   var filter = Builders<Scene>.Filter.Where(i => i.ID != null);
   var update = Builders<Scene>.Update.Unset("area.$[].discoveredBy");
   var result = collection.UpdateMany(filter, update, new UpdateOptions { IsUpsert = true});
}

For more context see my original post here: Remove array element from ALL documents using MongoDB C# driver

Check if you're not incrementing with some variable that its value is an empty string like ''.

Example:

$total = '';
$integers = range(1, 5);

foreach($integers as $integer) {
    $total += $integer;
}

iCalendar was based on a vCalendar and Outlook 2007 handles both formats well so it doesn't really matters which one you choose.

I'm not sure if this stands for Outlook 2003. I guess you should give it a try.

Outlook's default calendar format is iCalendar (*.ics)

namedtuples are immutable, just like standard tuples. You have two choices:

1. Use a different data structure, e.g. a class (or just a dictionary); or
2. Instead of updating the structure, replace it.

The former would look like:

class N(object):

    def __init__(self, ind, set, v):
        self.ind = ind
        self.set = set
        self.v = v

And the latter:

item = items[node.ind]
items[node.ind] = N(item.ind, item.set, node.v)

Edit: if you want the latter, Ignacio's answer does the same thing more neatly using baked-in functionality.

mbaird's answer works fine. Just be aware that there seems to be a bug in Android (2.1 at least), that if you set any individual corner's radius to 0, it forces all the corners to 0 (at least that's the case with "dp" units; I didn't try it with any other units).

I needed a shape where the top corners were rounded and the bottom corners were square. I got achieved this by setting the corners I wanted to be square to a value slightly larger than 0: 0.1dp. This still renders as square corners, but it doesn't force the other corners to be 0 radius.

According to MySQL documentation, you should be able to just enclose that datetime string in single quotes, ('YYYY-MM-DD HH:MM:SS') and it should work. Look here: Date and Time Literals

So, in your case, the command should be as follows:

UPDATE products SET former_date='2011-12-18 13:17:17' WHERE id=1

Slightly modifying answer by @Yogeesh Seralathan. His answer works perfectly, just run these commands at once.

adb shell input keyevent 26 && adb shell input touchscreen swipe 930 880 930 380 && adb shell input text XXXX && adb shell input keyevent 66

If you do have to do it this way, here's a few ways of doing it:

Disabling the button with ng-disabled

By far the easiest solution.

<input ng-disabled="!profileForm.$valid" ng-click="updateMyProfile()" ... >

Hiding the button (and showing something else) with ng-if

Might be OK if you're showing/hiding some complex markup.

<div ng-if="profileForm.$valid">
    <input ng-click="updateMyProfile()" ... >
</div>
<div ng-if="!profileForm.$valid">
    Sorry! We need all form fields properly filled out to continue.
</div>

(remember, there's no ng-else ...)

A mix of both

Communicating to the user where the button is (he won't look for it any longer), but explain why it can't be clicked.

<input ng-disabled="!profileForm.$valid" ng-click="updateMyProfile()" ... >
<div ng-if="!profileForm.$valid">
    Sorry! We need all form fields properly filled out to continue.
</div>

May use this-

#if defined CONDITION1 || defined CONDITION2
//your code here
#endif

This also does the same-

#if defined(CONDITION1) || defined(CONDITION2)
//your code here
#endif

Further-

• AND: #if defined CONDITION1 && defined CONDITION2
• XOR: #if defined CONDITION1 ^ defined CONDITION2
• AND NOT: #if defined CONDITION1 && !defined CONDITION2

Because you have used absolute positioning, and specified a top percentage, only margin-top will affect the location of your .item object. If instead you positioned it using bottom: 50%, then you'd need margin-bottom -8px to centre it, and margin-top would have no effect.

Margin affects the boundaries of an element in terms of positioning it, either absolutely as in your case, or relative to neighbouring elements. Imagine that margin is the foundations of your element on which it sits. They are typically the same size as it, but can be made larger or smaller on any or all of the four edges.

Your CSS tells the browser to position the top of your element the margin at a point 50% of the way down the page. However, as all elements are not a single pixel, the browser needs to know which part of it to line up 50% of the way down the page. For lining up the top of the element, it uses the top margin. By default this is in line with the top of the element, but you can alter it with CSS.

In your case, top 50% would result in the top of the element starting in the middle of the page. By applying a negative top margin, the browser uses the point 8px into the element from the top (ie the line across the middle of it) as the place to position at 50%.

If you apply a positive margin to the bottom, this extends the line the browser uses to position the bottom out away from the element itself, giving a gap between it and any adjacent element below, or affecting where it is placed absolutely if positioning based on the bottom.

To subtract timevals:

gettimeofday(&t0, 0);
/* ... */
gettimeofday(&t1, 0);
long elapsed = (t1.tv_sec-t0.tv_sec)*1000000 + t1.tv_usec-t0.tv_usec;

This is assuming you'll be working with intervals shorter than ~2000 seconds, at which point the arithmetic may overflow depending on the types used. If you need to work with longer intervals just change the last line to:

long long elapsed = (t1.tv_sec-t0.tv_sec)*1000000LL + t1.tv_usec-t0.tv_usec;

STEP 1: Include the following in OnConfiguring()

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        IConfigurationRoot configuration = new ConfigurationBuilder()
            .SetBasePath(AppDomain.CurrentDomain.BaseDirectory)
            .AddJsonFile("appsettings.json")
            .Build();
        optionsBuilder.UseSqlServer(configuration.GetConnectionString("DefaultConnection"));
    }

STEP 2: Create appsettings.json:

  {
    "ConnectionStrings": {       
      "DefaultConnection": "Server=YOURSERVERNAME; Database=YOURDATABASENAME; Trusted_Connection=True; MultipleActiveResultSets=true"        
    } 
  }

STEP 3: Hard copy appsettings.json to the correct directory

  Hard copy appsettings.json.config to the directory specified in the AppDomain.CurrentDomain.BaseDirectory directory. 
  Use your debugger to find out which directory that is.        

Assumption: you have already included package Microsoft.Extensions.Configuration.Json (get it from Nuget) in your project.

public static void SendMail(MailMessage Message)
{
    SmtpClient client = new SmtpClient();
    client.Host = "smtp.googlemail.com";
    client.Port = 587;
    client.UseDefaultCredentials = false;
    client.DeliveryMethod = SmtpDeliveryMethod.Network;
    client.EnableSsl = true;
    client.Credentials = new NetworkCredential("[email protected]", "password");
    client.Send(Message); 
}

You can also use Url.Action for the path instead like so:

$.ajax({
        url: "@Url.Action("Holiday", "Calendar", new { area = "", year= (val * 1) + 1 })",                
        type: "GET",           
        success: function (partialViewResult) {            
            $("#refTable").html(partialViewResult);
        }
    });

As the file object reads the file, it uses a pointer to keep track of where it is. If you read part of the file, then go back to it later it will pick up where you left off. If you read the whole file, and go back to the same file object, it will be like reading an empty file because the pointer is at the end of the file and there is nothing left to read. You can use file.tell() to see where in the file the pointer is and file.seek to set the pointer. For example:

>>> file = open('myfile.txt')
>>> file.tell()
0
>>> file.readline()
'one\n'
>>> file.tell()
4L
>>> file.readline()
'2\n'
>>> file.tell()
6L
>>> file.seek(4)
>>> file.readline()
'2\n'

Also, you should know that file.readlines() reads the whole file and stores it as a list. That's useful to know because you can replace:

for line in file.readlines():
    #do stuff
file.seek(0)
for line in file.readlines():
    #do more stuff

with:

lines = file.readlines()
for each_line in lines:
    #do stuff
for each_line in lines:
    #do more stuff

You can also iterate over a file, one line at a time, without holding the whole file in memory (this can be very useful for very large files) by doing:

for line in file:
    #do stuff

You can change the comment character to something besides # like this:

git config --global core.commentchar "@"

Download version tar.gz for windows and just extract files to the folder by your needs. On the left pane, you can select which version of openjdk to download

As has been said, datetime has no format/string representational format.

You can change the string output with some formatting.

To convert your string to a datetime:

declare @date nvarchar(25) 
set @date = '2011-09-28 18:01:00' 

-- To datetime datatype
SELECT CONVERT(datetime, @date)

Gives:

-----------------------
2011-09-28 18:01:00.000

(1 row(s) affected)

To convert that to the string you want:

-- To VARCHAR of your desired format
SELECT CONVERT(VARCHAR(10), CONVERT(datetime, @date), 105) +' '+ CONVERT(VARCHAR(8), CONVERT(datetime, @date), 108)

Gives:

-------------------
28-09-2011 18:01:00

(1 row(s) affected)

execl("/home/vlc", 
  "/home/vlc", "/home/my movies/the movie i want to see.mkv", 
  (char*) NULL);

You need to specify all arguments, included argv[0] which isn't taken from the executable.

Also make sure the final NULL gets cast to char*.

May be You are not registering the Controllers. Try below code:

Step 1. Write your own controller factory class ControllerFactory :DefaultControllerFactory by implementing defaultcontrollerfactory in models folder

  public class ControllerFactory :DefaultControllerFactory
    {
    protected override IController GetControllerInstance(RequestContext         requestContext, Type controllerType)
        {
            try
            {
                if (controllerType == null)
                    throw new ArgumentNullException("controllerType");

                if (!typeof(IController).IsAssignableFrom(controllerType))
                    throw new ArgumentException(string.Format(
                        "Type requested is not a controller: {0}",
                        controllerType.Name),
                        "controllerType");

                return MvcUnityContainer.Container.Resolve(controllerType) as IController;
            }
            catch
            {
                return null;
            }

        }
        public static class MvcUnityContainer
        {
            public static UnityContainer Container { get; set; }
        }
    }

Step 2:Regigster it in BootStrap: inBuildUnityContainer method

private static IUnityContainer BuildUnityContainer()
    {
      var container = new UnityContainer();

      // register all your components with the container here
      // it is NOT necessary to register your controllers

      // e.g. container.RegisterType<ITestService, TestService>();    
      //RegisterTypes(container);
      container = new UnityContainer();
      container.RegisterType<IProductRepository, ProductRepository>();


      MvcUnityContainer.Container = container;
      return container;
    }

Step 3: In Global Asax.

protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();

            WebApiConfig.Register(GlobalConfiguration.Configuration);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
            AuthConfig.RegisterAuth();
            Bootstrapper.Initialise();
            ControllerBuilder.Current.SetControllerFactory(typeof(ControllerFactory));

        }

And you are done

You can't depend on the file having a BOM. UTF-8 doesn't require it. And non-Unicode encodings don't even have a BOM. There are, however, other ways to detect the encoding.

UTF-32

BOM is 00 00 FE FF (for BE) or FF FE 00 00 (for LE).

But UTF-32 is easy to detect even without a BOM. This is because the Unicode code point range is restricted to U+10FFFF, and thus UTF-32 units always have the pattern 00 {00-10} xx xx (for BE) or xx xx {00-10} 00 (for LE). If the data has a length that's a multiple of 4, and follows one of these patterns, you can safely assume it's UTF-32. False positives are nearly impossible due to the rarity of 00 bytes in byte-oriented encodings.

US-ASCII

No BOM, but you don't need one. ASCII can be easily identified by the lack of bytes in the 80-FF range.

UTF-8

BOM is EF BB BF. But you can't rely on this. Lots of UTF-8 files don't have a BOM, especially if they originated on non-Windows systems.

But you can safely assume that if a file validates as UTF-8, it is UTF-8. False positives are rare.

Specifically, given that the data is not ASCII, the false positive rate for a 2-byte sequence is only 3.9% (1920/49152). For a 7-byte sequence, it's less than 1%. For a 12-byte sequence, it's less than 0.1%. For a 24-byte sequence, it's less than 1 in a million.

UTF-16

BOM is FE FF (for BE) or FF FE (for LE). Note that the UTF-16LE BOM is found at the start of the UTF-32LE BOM, so check UTF-32 first.

If you happen to have a file that consists mainly of ISO-8859-1 characters, having half of the file's bytes be 00 would also be a strong indicator of UTF-16.

Otherwise, the only reliable way to recognize UTF-16 without a BOM is to look for surrogate pairs (D[8-B]xx D[C-F]xx), but non-BMP characters are too rarely-used to make this approach practical.

XML

If your file starts with the bytes 3C 3F 78 6D 6C (i.e., the ASCII characters "<?xml"), then look for an encoding= declaration. If present, then use that encoding. If absent, then assume UTF-8, which is the default XML encoding.

If you need to support EBCDIC, also look for the equivalent sequence 4C 6F A7 94 93.

In general, if you have a file format that contains an encoding declaration, then look for that declaration rather than trying to guess the encoding.

None of the above

There are hundreds of other encodings, which require more effort to detect. I recommend trying Mozilla's charset detector or a .NET port of it.

A reasonable default

If you've ruled out the UTF encodings, and don't have an encoding declaration or statistical detection that points to a different encoding, assume ISO-8859-1 or the closely related Windows-1252. (Note that the latest HTML standard requires a “ISO-8859-1” declaration to be interpreted as Windows-1252.) Being Windows' default code page for English (and other popular languages like Spanish, Portuguese, German, and French), it's the most commonly encountered encoding other than UTF-8.

I am generally using the way posted by Barry Wark and Rahul Gupta.

Although, I do not like repeating the same words in both .h and .m file. Note, that in the following example the line is almost identical in both files:

// file.h
extern NSString* const MyConst;

//file.m
NSString* const MyConst = @"Lorem ipsum";

Therefore, what I like to do is to use some C preprocessor machinery. Let me explain through the example.

I have a header file which defines the macro STR_CONST(name, value):

// StringConsts.h
#ifdef SYNTHESIZE_CONSTS
# define STR_CONST(name, value) NSString* const name = @ value
#else
# define STR_CONST(name, value) extern NSString* const name
#endif

The in my .h/.m pair where I want to define the constant I do the following:

// myfile.h
#import <StringConsts.h>

STR_CONST(MyConst, "Lorem Ipsum");
STR_CONST(MyOtherConst, "Hello world");

// myfile.m
#define SYNTHESIZE_CONSTS
#import "myfile.h"

et voila, I have all the information about the constants in .h file only.

In Java, by default AES supports a 128 Bit key, if you plans to use 192 Bit or 256 Bit key, java complier will throw Illegal key size Exception, which you are getting.

The solution is as victor & James suggested, you will need to download JCE (Java Cryptography Extension) as per your JRE version,(java6, java7 or java8).

The JCE zip contains following JAR:

1. local_policy.jar
2. US_export_policy.jar

You need to replace these jar form your <JAVA_HOME>/jre/lib/security. if you are on a unix system the will probably refer to /home/urs/usr/lib/jvm/java-<version>-oracle/

Sometimes just replacing local_policy.jar, US_export_policy.jar in security folder doesn't work on unix, so I suggest to copy security folder to your desktop first, replace the jar's @Desktop/security folder, delete the security folder from /jre/lib/ & move the Desktop security folder to /jre/lib/.

eg :: sudo mv security /usr/lib/jvm/java-7-oracle/jre/lib

! is a logical NOT operator, it's a boolean operator that will invert something to its opposite.

Although you can bypass the parentheses of the invoked function by using the BANG (!) before the function, it will still invert the return, which might not be what you wanted. As in the case of an IEFE, it would return undefined, which when inverted becomes the boolean true.

Instead, use the closing parenthesis and the BANG (!) if needed.

// I'm going to leave the closing () in all examples as invoking the function with just ! and () takes away from what's happening.

(function(){ return false; }());
=> false

!(function(){ return false; }());
=> true

!!(function(){ return false; }());
=> false

!!!(function(){ return false; }());
=> true

Other Operators that work...

+(function(){ return false; }());
=> 0

-(function(){ return false; }());
=> -0

~(function(){ return false; }());
=> -1

Combined Operators...

+!(function(){ return false; }());
=> 1

-!(function(){ return false; }());
=> -1

!+(function(){ return false; }());
=> true

!-(function(){ return false; }());
=> true

~!(function(){ return false; }());
=> -2

~!!(function(){ return false; }());
=> -1

+~(function(){ return false; }());
+> -1

Perhaps involve the activity's life-cycle methods to achieve this:

Handler handler = new Handler();

@Override
protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      handler.post(sendData);
}

@Override
protected void onDestroy() {
      super.onDestroy();
      handler.removeCallbacks(sendData);
}


private final Runnable sendData = new Runnable(){
    public void run(){
        try {
            //prepare and send the data here..


            handler.postDelayed(this, 1000);    
        }
        catch (Exception e) {
            e.printStackTrace();
        }   
    }
};

In this approach, if you press back-key on your activity or call finish();, it will also stop the postDelayed callings.

Use this for slivers AppBar

SliverAppBar (
        automaticallyImplyLeading: false,
        elevation: 0,

        pinned: true,
      ),

Use this for normal Appbar

 appBar: AppBar(
    title: Text
    ("You decide on the appbar name"
    style: TextStyle(color: Colors.black,), 
    elevation: 0,
    brightness: Brightness.light,

For the me issue was that I had 2 other Android Emulators running. Once I closed those, I was able to start the new one.

The best way in my opinion is Reflection as others have recommended. Here's a sample that evaluates each local field for null. If it finds one that is not null, method will return false.

public class User {

    String id = null;
    String name = null;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public boolean isNull() {
        Field fields[] = this.getClass().getDeclaredFields();
        for (Field f : fields) {
            try {
                Object value = f.get(this);
                if (value != null) {
                    return false;
                }
            }
            catch (IllegalArgumentException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            catch (IllegalAccessException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }


        }
        return true;

    }

    public static void main(String args[]) {
        System.out.println(new User().isNull());
    }
}

$query    =    "SELECT username, userid FROM user WHERE username = 'admin' ";
$result    =    $conn->query($query);

if (!$result) {
  echo 'Could not run query: ' . mysql_error();
  exit;
}

$arrayResult    =    mysql_fetch_array($result);

//Now you can access $arrayResult like this

$arrayResult['userid'];    // output will be userid which will be in database
$arrayResult['username'];  // output will be admin

//Note- userid and username will be column name of user table.

Based on the answer I linked to in my comment above, this should work:

delete from
(
select pf.* From PRODUCTFILTERS pf 
where pf.id>=200 
And pf.rowid in 
  (
     Select rowid from PRODUCTFILTERS 
     inner join PRODUCTS on PRODUCTFILTERS.PRODUCTID = PRODUCTS.ID 
     And PRODUCTS.NAME= 'Mark'
  )
); 

or

delete from PRODUCTFILTERS where rowid in
(
select pf.rowid From PRODUCTFILTERS pf 
where pf.id>=200 
And pf.rowid in 
  (
     Select PRODUCTFILTERS.rowid from PRODUCTFILTERS 
     inner join PRODUCTS on PRODUCTFILTERS.PRODUCTID = PRODUCTS.ID 
     And PRODUCTS.NAME= 'Mark'
  )
); 

@rvighne solution works well, but as identified in the comments ParentElement and ClassList both have compatibility issues. To make it more compatible, I have used:

function findAncestor (el, cls) {
    while ((el = el.parentNode) && el.className.indexOf(cls) < 0);
    return el;
}

• parentNode property instead of the parentElement property
• indexOf method on the className property instead of the contains method on the classList property.

Of course, indexOf is simply looking for the presence of that string, it does not care if it is the whole string or not. So if you had another element with class 'ancestor-type' it would still return as having found 'ancestor', if this is a problem for you, perhaps you can use regexp to find an exact match.

First, squash all your commits into a single commit using git rebase --interactive. Now you're left with two commits to squash. To do so, read any of

• How do I combine the first two commits of a Git repository?
• git: how to squash the first two commits?

Suppose you have the following code:

import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;

public class Test {
    public static void main(String[] s) {
        Map<String, Boolean> whoLetDogsOut = new ConcurrentHashMap<>();
        whoLetDogsOut.computeIfAbsent("snoop", k -> f(k));
        whoLetDogsOut.computeIfAbsent("snoop", k -> f(k));
    }
    static boolean f(String s) {
        System.out.println("creating a value for \""+s+'"');
        return s.isEmpty();
    }
}

Then you will see the message creating a value for "snoop" exactly once as on the second invocation of computeIfAbsent there is already a value for that key. The k in the lambda expression k -> f(k) is just a placeolder (parameter) for the key which the map will pass to your lambda for computing the value. So in the example the key is passed to the function invocation.

Alternatively you could write: whoLetDogsOut.computeIfAbsent("snoop", k -> k.isEmpty()); to achieve the same result without a helper method (but you won’t see the debugging output then). And even simpler, as it is a simple delegation to an existing method you could write: whoLetDogsOut.computeIfAbsent("snoop", String::isEmpty); This delegation does not need any parameters to be written.

To be closer to the example in your question, you could write it as whoLetDogsOut.computeIfAbsent("snoop", key -> tryToLetOut(key)); (it doesn’t matter whether you name the parameter k or key). Or write it as whoLetDogsOut.computeIfAbsent("snoop", MyClass::tryToLetOut); if tryToLetOut is static or whoLetDogsOut.computeIfAbsent("snoop", this::tryToLetOut); if tryToLetOut is an instance method.

There are several ways to add files to an existing Java project in Eclipse. So lets assume you have already created the Java project in Eclipse (e.g. using File -> New -> Project... - and select Java project).

To get Java files into the new project you can do any of the following. Note that there are other ways as well. The sequence is my preference.

• Drag the files into the Navigator view directly from the native file manager. You must create any needed Java packages first. This method is best for a few files in an existing Java package.
• Use File -> Import... - select File System. Here you can then select exactly which files to import into the new project and in which Java package to put them. This is extremely handy if you want to import many files or there are multiple Java packages.
• Copy the fires directly to the folder/directory in the workspace and then use File -> Refresh to refresh the Eclipse view of the native system. Remember to select the new project before the refresh.

The last one is what you did - minus the refresh...

You are right, it's confusing that SQL Server allows you to create duplicate indexes on the same field(s). But the fact that you can create another doesn't indicate that the PK index doesn't also already exist.

The additional index does no good, but the only harm (very small) is the additional file size and row-creation overhead.

This assumes that the content is in column B on each sheet (since it's not clear how you determine the column on each sheet.) and the last row of that column is also the last row of the sheet.

$xlCellTypeLastCell = 11 
$startRow = 5 
$col = 2 

$excel = New-Object -Com Excel.Application
$wb = $excel.Workbooks.Open("C:\Users\Administrator\my_test.xls")

for ($i = 1; $i -le $wb.Sheets.Count; $i++)
{
    $sh = $wb.Sheets.Item($i)
    $endRow = $sh.UsedRange.SpecialCells($xlCellTypeLastCell).Row
    $city = $sh.Cells.Item($startRow, $col).Value2
    $rangeAddress = $sh.Cells.Item($startRow + 1, $col).Address() + ":" + $sh.Cells.Item($endRow, $col).Address()
    $sh.Range($rangeAddress).Value2 | foreach 
    {
        New-Object PSObject -Property @{ City = $city; Area = $_ }
    }
}

$excel.Workbooks.Close()

Have a look at this sample:

public class A {
  //statements
}

public class B extends A {
  public void foo() { }
}

A a=new B();

//To execute **foo()** method.

((B)a).foo();

If you are looking for a plain JS solution, then you just use insertBefore() against nextSibling.

Something like:

parentGuest.parentNode.insertBefore(childGuest, parentGuest.nextSibling);

Note that default value of nextSibling is null, so, you don't need to do anything special for that.

Update: You don't even need the if checking presence of parentGuest.nextSibling like the currently accepted answer does, because if there's no next sibling, it will return null, and passing null to the 2nd argument of insertBefore() means: append at the end.

Reference:

• nextSibling
• insertBefore

.

IF you are using jQuery (ignore otherwise, I have stated plain JS answer above), you can leverage the convenient after() method:

$("#one").after("<li id='two'>");

Reference:

• jQuery after()

setLoanItem is an instance method, meaning you need an instance of the Media class in order to call it. You're attempting to call it on the Media type itself.

You may want to look into some basic object-oriented tutorials to see how static/instance members work.

var str = "IAMA JavaScript Developer";
var a=str.split(''), b = a.length;
for (var i=0; i<b; i++) {
    a.unshift(a.splice(1+i,1).shift())
}
a.shift();
alert(a.join(''));

Thanks for the suggestions in the comments. I made a bit of a dirty hack to get what I want without having to create my own image. With javascript I first hide the default tag that's being used for the down arrow, like so:

$('b[role="presentation"]').hide();

I then included font-awesome in my page and add my own down arrow, again with a line of javascript, to replace the default one:

$('.select2-arrow').append('<i class="fa fa-angle-down"></i>');

Then with CSS I style the select boxes. I set the height, change the background color of the arrow area to a gradient black, change the width, font-size and also the color of the down arrow to white:

.select2-container .select2-choice {
    padding: 5px 10px;
    height: 40px;
    width: 132px; 
    font-size: 1.2em;  
}

.select2-container .select2-choice .select2-arrow {
    background-image: -khtml-gradient(linear, left top, left bottom, from(#424242), to(#030303));
    background-image: -moz-linear-gradient(top, #424242, #030303);
    background-image: -ms-linear-gradient(top, #424242, #030303);
    background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #424242), color-stop(100%, #030303));
    background-image: -webkit-linear-gradient(top, #424242, #030303);
    background-image: -o-linear-gradient(top, #424242, #030303);
    background-image: linear-gradient(#424242, #030303);
    width: 40px;
    color: #fff;
    font-size: 1.3em;
    padding: 4px 12px;
}

The result is the styling the way I want it:

Update 5/6/2015 As @Katie Lacy mentioned in the other answer the classnames have been changed in version 4 of Select2. The updated CSS with the new classnames should look like this:

.select2-container--default .select2-selection--single{
    padding:6px;
    height: 37px;
    width: 148px; 
    font-size: 1.2em;  
    position: relative;
}

.select2-container--default .select2-selection--single .select2-selection__arrow {
    background-image: -khtml-gradient(linear, left top, left bottom, from(#424242), to(#030303));
    background-image: -moz-linear-gradient(top, #424242, #030303);
    background-image: -ms-linear-gradient(top, #424242, #030303);
    background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #424242), color-stop(100%, #030303));
    background-image: -webkit-linear-gradient(top, #424242, #030303);
    background-image: -o-linear-gradient(top, #424242, #030303);
    background-image: linear-gradient(#424242, #030303);
    width: 40px;
    color: #fff;
    font-size: 1.3em;
    padding: 4px 12px;
    height: 27px;
    position: absolute;
    top: 0px;
    right: 0px;
    width: 20px;
}

JS:

$('b[role="presentation"]').hide();
$('.select2-selection__arrow').append('<i class="fa fa-angle-down"></i>');

It's simple

input {border:0;outline:0;}
input:focus {outline:none!important;}

I'll try and break it down (example from documention)

/* 
 *   The cellForRowAtIndexPath takes for argument the tableView (so if the same object
 *   is delegate for several tableViews it can identify which one is asking for a cell),
 *   and an indexPath which determines which row and section the cell is returned for. 
 */ 
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    /*
     *   This is an important bit, it asks the table view if it has any available cells
     *   already created which it is not using (if they are offScreen), so that it can
     *   reuse them (saving the time of alloc/init/load from xib a new cell ).
     *   The identifier is there to differentiate between different types of cells
     *   (you can display different types of cells in the same table view)
     */

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MyIdentifier"];

    /*
     *   If the cell is nil it means no cell was available for reuse and that we should
     *   create a new one.
     */
    if (cell == nil) {

        /* 
         *   Actually create a new cell (with an identifier so that it can be dequeued). 
         */

        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"MyIdentifier"] autorelease];

        cell.selectionStyle = UITableViewCellSelectionStyleNone;

    }

    /*
     *   Now that we have a cell we can configure it to display the data corresponding to
     *   this row/section
     */

    NSDictionary *item = (NSDictionary *)[self.content objectAtIndex:indexPath.row];
    cell.textLabel.text = [item objectForKey:@"mainTitleKey"];
    cell.detailTextLabel.text = [item objectForKey:@"secondaryTitleKey"];
    NSString *path = [[NSBundle mainBundle] pathForResource:[item objectForKey:@"imageKey"] ofType:@"png"];
    UIImage *theImage = [UIImage imageWithContentsOfFile:path];
    cell.imageView.image = theImage;

    /* Now that the cell is configured we return it to the table view so that it can display it */

    return cell;

}

This is a DataSource method so it will be called on whichever object has declared itself as the DataSource of the UITableView. It is called when the table view actually needs to display the cell onscreen, based on the number of rows and sections (which you specify in other DataSource methods).

Display property 'inline-block' will place both headers next to each other. You can run this code snippet to see it

<h1 style="display: inline-block" >Text 1</h1>
<h1 style="display: inline-block" >Text 2</h1>

Editor warning: This solution is computationally inefficient and may bring down your connection for a large table.

NB - You need to do this first on a test copy of your table!

When I did it, I found that unless I also included AND n1.id <> n2.id, it deleted every row in the table.

1. If you want to keep the row with the lowest id value:

   DELETE n1 FROM names n1, names n2 WHERE n1.id > n2.id AND n1.name = n2.name
   

2. If you want to keep the row with the highest id value:

   DELETE n1 FROM names n1, names n2 WHERE n1.id < n2.id AND n1.name = n2.name
   

I used this method in MySQL 5.1

Not sure about other versions.

Update: Since people Googling for removing duplicates end up here
Although the OP's question is about DELETE, please be advised that using INSERT and DISTINCT is much faster. For a database with 8 million rows, the below query took 13 minutes, while using DELETE, it took more than 2 hours and yet didn't complete.

INSERT INTO tempTableName(cellId,attributeId,entityRowId,value)
    SELECT DISTINCT cellId,attributeId,entityRowId,value
    FROM tableName;

I don't know the answer for SQL Server but...

In MySQL save it as FLOAT( 10, 6 )

This is the official recommendation from the Google developer documentation.

CREATE TABLE `coords` (
  `lat` FLOAT( 10, 6 ) NOT NULL ,
  `lng` FLOAT( 10, 6 ) NOT NULL ,
) ENGINE = MYISAM ;

                mb.panButtons.Controls.Add(b);
                b.Location = new Point(3, 3);
                b.TabIndex = Buttons.FindIndex(i => i.Text == b.Text);
                b.Click += new EventHandler(mb.Button_Click);
            }
            ButtonWidth = mb.panButtons.Width;
            ButtonHeight = mb.panButtons.Height;

            //Set Widths
            if (ButtonWidth > ImageWidth + LabelWidth)
            {
                Labels.ForEach(l => l.MinimumSize = new Size(ButtonWidth - ImageWidth - mb.ScrollBarWidth(Labels), 1));
                mb.panText.Height = Labels.Sum(l => l.Height);
                mb.panText.MinimumSize = new Size(Labels.Max(x => x.Width) + mb.ScrollBarWidth(Labels), ImageHeight);
                mb.panText.MaximumSize = new Size(Labels.Max(x => x.Width) + mb.ScrollBarWidth(Labels), 300);
                LabelWidth = mb.panText.Width;
                LabelHeight = mb.panText.Height;
            }
            TotalWidth = ImageWidth + LabelWidth;

            //Set Height
            TotalHeight = LabelHeight + ButtonHeight;

            mb.panButtons.Location = new Point(TotalWidth - ButtonWidth + 9, mb.panText.Location.Y + mb.panText.Height);

            mb.Size = new Size(TotalWidth + 25, TotalHeight + 47);
            mb.ShowDialog();
            return mb.Result;
        }

        private FlowLayoutPanel panText;
        private FlowLayoutPanel panButtons;
        private int ScrollBarWidth(List<Label> Labels)
        {
            return (Labels.Sum(l => l.Height) > 300) ? 23 : 6;
        }

        private void Button_Click(object sender, EventArgs e)
        {
            Result = ((Button)sender).Text;
            Close();
        }

        private string Result = "";
    }
}   

As of C# 7 you could also use this:

if (clientsParsed["objects"] is JArray clients) 
{
    foreach (JObject item in clients.Children())
    {
        if (item["thisParameter"] as JToken itemToken) 
        {
            command.Parameters["@MyParameter"].Value = JTokenToSql(itemToken);
        }
    }
}

The is Operator checks the Type and if its corrects the Value is inside the clients variable.

Google Chrome Developer Tools has (a currently experimental) feature called CSS Overview which will allow you to find unused CSS rules.

To enable it follow these steps:

1. Open up DevTools (Command+Option+I on Mac; Control+Shift+I on Windows)
2. Head over to DevTool Settings (Function+F1 on Mac; F1 on Windows)
3. Click open the Experiments section
4. Enable the CSS Overview option

This is a simple and maybe not the best solution, but it works.

On the line above the line you get your error, paste this:

// eslint-disable-next-line no-restricted-globals

shuf -i 2000-65000 -n 1

Enjoy!

Edit: The range is inclusive.

Try serialize(). It converts an array into a string format, you can then use unserialize() to convert it back to an array. Scripts like WordPress use this to save multiple values to a single database field.

You can also use json_encode() as Rob said, which maybe useful if you want to read the cookie in javascript.

A very simple but inefficient solution without any external library is:

public static String unescapeHtml3( String str ) {
    try {
        HTMLDocument doc = new HTMLDocument();
        new HTMLEditorKit().read( new StringReader( "<html><body>" + str ), doc, 0 );
        return doc.getText( 1, doc.getLength() );
    } catch( Exception ex ) {
        return str;
    }
}

This should be use only if you have only small count of string to decode.

I think you've misunderstood some python syntax, the following does two assignments:

In [11]: a = b = 1

In [12]: a
Out[12]: 1

In [13]: b
Out[13]: 1

So in your code it was as if you were doing:

sum = df['budget'] + df['actual']  # a Series
# and
df['variance'] = df['budget'] + df['actual']  # assigned to a column

The latter creates a new column for df:

In [21]: df
Out[21]:
  cluster                 date  budget  actual
0       a  2014-01-01 00:00:00   11000   10000
1       a  2014-02-01 00:00:00    1200    1000
2       a  2014-03-01 00:00:00     200     100
3       b  2014-04-01 00:00:00     200     300
4       b  2014-05-01 00:00:00     400     450
5       c  2014-06-01 00:00:00     700    1000
6       c  2014-07-01 00:00:00    1200    1000
7       c  2014-08-01 00:00:00     200     100
8       c  2014-09-01 00:00:00     200     300

In [22]: df['variance'] = df['budget'] + df['actual']

In [23]: df
Out[23]:
  cluster                 date  budget  actual  variance
0       a  2014-01-01 00:00:00   11000   10000     21000
1       a  2014-02-01 00:00:00    1200    1000      2200
2       a  2014-03-01 00:00:00     200     100       300
3       b  2014-04-01 00:00:00     200     300       500
4       b  2014-05-01 00:00:00     400     450       850
5       c  2014-06-01 00:00:00     700    1000      1700
6       c  2014-07-01 00:00:00    1200    1000      2200
7       c  2014-08-01 00:00:00     200     100       300
8       c  2014-09-01 00:00:00     200     300       500

As an aside, you shouldn't use sum as a variable name as the overrides the built-in sum function.

You could make two forms with 2 different actions

<form action="login.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="submit" value="Login">
</form>

<br />

<form action="register.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="submit" value="Register">
</form>

Or do this

<form action="doStuff.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="hidden" name="action" value="login">
    <input type="submit" value="Login">
</form>

<br />

<form action="doStuff.php" method="post">
    <input type="text" name="user">
    <input type="password" name="password">
    <input type="hidden" name="action" value="register">
    <input type="submit" value="Register">
</form>

Then you PHP file would work as a switch($_POST['action']) ... furthermore, they can't click on both links at the same time or make a simultaneous request, each submit is a separate request.

Your PHP would then go on with the switch logic or have different php files doing a login procedure then a registration procedure

import javax.swing.*;
class Demo extends JFrame
{
           String str1;
           Demo(String s1)
           {
             str1=s1;
            JOptionPane.showMessageDialog(null,"your message : "+str1);
            }
            public static void main (String ar[])
            {
             new Demo("Java");
            }
}

Try using ESAPIs Encryption methods. Its easy to configure and you can also easily change your keys.

http://owasp-esapi-java.googlecode.com/svn/trunk_doc/latest/org/owasp/esapi/Encryptor.html

You

1)encrypt 2)decrypt 3)sign 4)unsign 5)hashing 6)time based signatures and much more with just one library.

#if !defined(MANUF) || !defined(SERIAL) || !defined(MODEL)

Please use

-- turn on statistics IO for IO related 
SET STATISTICS IO ON 
GO

and for time calculation use

SET STATISTICS TIME ON
GO

then It will give result for every query . In messages window near query input window.

Note: this solution works only if the slaves have the same directory structure as the master. pwd() will return the workspace directory on the master due to JENKINS-33511.

I used to do it using pwd() functionality of pipeline plugin. So, if you need to get a workspace on slave, you may do smth like this:

node('label'){
    //now you are on slave labeled with 'label'
    def workspace = pwd()
    //${workspace} will now contain an absolute path to job workspace on slave 
}

Use:

memset(my_custom_data, 0, sizeof(my_custom_data));

Or:

memset(my_custom_data, 0, strlen(my_custom_data));

Expanding on the answers provided here.

You can just do set idx = 1 to set a variable, but that syntax is not recommended because the variable name may clash with a set sub-command. As an example set w=1 would not be valid.

This means that you should prefer the syntax: set variable idx = 1 or set var idx = 1.

Last but not least, you can just use your trusty old print command, since it evaluates an expression. The only difference being that he also prints the result of the expression.

(gdb) p idx = 1
$1 = 1

You can read more about gdb here.

Using bash regular expressions:

re="http://([^/]+)/"
if [[ $name =~ $re ]]; then echo ${BASH_REMATCH[1]}; fi

Edit - OP asked for explanation of syntax. Regular expression syntax is a large topic which I can't explain in full here, but I will attempt to explain enough to understand the example.

re="http://([^/]+)/"

This is the regular expression stored in a bash variable, re - i.e. what you want your input string to match, and hopefully extract a substring. Breaking it down:

• http:// is just a string - the input string must contain this substring for the regular expression to match
• [] Normally square brackets are used say "match any character within the brackets". So c[ao]t would match both "cat" and "cot". The ^ character within the [] modifies this to say "match any character except those within the square brackets. So in this case [^/] will match any character apart from "/".
• The square bracket expression will only match one character. Adding a + to the end of it says "match 1 or more of the preceding sub-expression". So [^/]+ matches 1 or more of the set of all characters, excluding "/".
• Putting () parentheses around a subexpression says that you want to save whatever matched that subexpression for later processing. If the language you are using supports this, it will provide some mechanism to retrieve these submatches. For bash, it is the BASH_REMATCH array.
• Finally we do an exact match on "/" to make sure we match all the way to end of the fully qualified domain name and the following "/"

Next, we have to test the input string against the regular expression to see if it matches. We can use a bash conditional to do that:

if [[ $name =~ $re ]]; then
    echo ${BASH_REMATCH[1]}
fi

In bash, the [[ ]] specify an extended conditional test, and may contain the =~ bash regular expression operator. In this case we test whether the input string $name matches the regular expression $re. If it does match, then due to the construction of the regular expression, we are guaranteed that we will have a submatch (from the parentheses ()), and we can access it using the BASH_REMATCH array:

• Element 0 of this array ${BASH_REMATCH[0]} will be the entire string matched by the regular expression, i.e. "http://www.google.com/".
• Subsequent elements of this array will be subsequent results of submatches. Note you can have multiple submatch () within a regular expression - The BASH_REMATCH elements will correspond to these in order. So in this case ${BASH_REMATCH[1]} will contain "www.google.com", which I think is the string you want.

Note that the contents of the BASH_REMATCH array only apply to the last time the regular expression =~ operator was used. So if you go on to do more regular expression matches, you must save the contents you need from this array each time.

This may seem like a lengthy description, but I have really glossed over several of the intricacies of regular expressions. They can be quite powerful, and I believe with decent performance, but the regular expression syntax is complex. Also regular expression implementations vary, so different languages will support different features and may have subtle differences in syntax. In particular escaping of characters within a regular expression can be a thorny issue, especially when those characters would have an otherwise different meaning in the given language.

Note that instead of setting the $re variable on a separate line and referring to this variable in the condition, you can put the regular expression directly into the condition. However in bash 3.2, the rules were changed regarding whether quotes around such literal regular expressions are required or not. Putting the regular expression in a separate variable is a straightforward way around this, so that the condition works as expected in all bash versions that support the =~ match operator.

Go to the repo-browser right-click the file and use 'Save As', I'm using TortoiseSVN though.

I was having the same problem, none of the posted solutions helped. Finally, I figured out what I was doing wrong. When I installed the Java JDK it asked me for a directiy where I wanted to install. I changed the directory to where I wanted the code to go. It then asked for a directory where it could install the Runtime Environment and I selected the SAME DIRECTORY where I installed the JDK. It over wrote my lib folder and erased the tools.jar. Be sure to use different folders during the install. I used my custom folder for the JDK and the default folder for the RE and everything worked fine.

Peoples, dont forget that you could actually get something more from it. I mean UTM tracking for example. https://developers.google.com/analytics/devguides/collection/android/v4/campaigns

public static final String MODULE_ICON_PACK_FREE = "com.example.iconpack_free";
public static final String APP_STORE_URI =
        "market://details?id=%s&referrer=utm_source=%s&utm_medium=app&utm_campaign=plugin";
public static final String APP_STORE_GENERIC_URI =
        "https://play.google.com/store/apps/details?id=%s&referrer=utm_source=%s&utm_medium=app&utm_campaign=plugin";

try {
    startActivity(new Intent(
        Intent.ACTION_VIEW,
        Uri.parse(String.format(Locale.US,
            APP_STORE_URI,
            MODULE_ICON_PACK_FREE,
            getPackageName()))).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
} catch (android.content.ActivityNotFoundException anfe) {
    startActivity(new Intent(
        Intent.ACTION_VIEW,
        Uri.parse(String.format(Locale.US,
            APP_STORE_GENERIC_URI,
            MODULE_ICON_PACK_FREE,
            getPackageName()))).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
}

I am sorry everyone that this is the solution the true one where you dont have to actually set the padding.

http://jsfiddle.net/techsin/TyXRY/1/

What i have done...

• Applied two gradients on background with both having one start and end color. Instead of using solid color. Reason being that you can't have two solid colors for one background.
• Then applied different background-clip property to each.
• thus making one color extend to content box and other to border, revealing the padding.

Clever if i say so to myself.

div {
    padding: 35px;
    background-image:
      linear-gradient(to bottom,
        rgba(240, 255, 40, 1) 0%,
        rgba(240, 255, 40, 1) 100%),
      linear-gradient(to bottom,
        rgba(240, 40, 40, 1) 0%,
        rgba(240, 40, 40, 1) 100%);
    background-clip: content-box, padding-box;
}

Your compound PRIMARY KEY specification already does what you want. Omit the line that's giving you a syntax error, and omit the redundant CONSTRAINT (already implied), too:

 CREATE TABLE tags
      (
               question_id INTEGER NOT NULL,
               tag_id SERIAL NOT NULL,
               tag1 VARCHAR(20),
               tag2 VARCHAR(20),
               tag3 VARCHAR(20),
               PRIMARY KEY(question_id, tag_id)
      );

NOTICE:  CREATE TABLE will create implicit sequence "tags_tag_id_seq" for serial column "tags.tag_id"
    NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "tags_pkey" for table "tags"
    CREATE TABLE
    pg=> \d tags
                                         Table "public.tags"
       Column    |         Type          |                       Modifiers       
    -------------+-----------------------+-------------------------------------------------------

     tag_id      | integer               | not null default nextval('tags_tag_id_seq'::regclass)
     tag1        | character varying(20) |
     tag2        | character varying(20) |

    Indexes:
        "tags_pkey" PRIMARY KEY, btree (question_id, tag_id)

I had the same issue. I was using eclipse platform and server was missing in my show view. To fix this go:

• help>install new software

• in work with : select : "Indigo Update Site - http://download.eclipse.org/releases/indigo/" , once selected, all available software will be displayed in the section under type filter text

• Expand “Web, XML, and Java EE Development” and select "JST Server adapters extensions"

• then click next and finish. The server should be displayed in show view

b1 = (Button) findViewById(R.id.click_me);
        b1.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {

                Intent i = new Intent(MainActivity.this, SecondActivity.class);
                startActivity(i);

            }
        });

Can try :

var arr = [10,3,4,5,3,4,3,8,3,6,3,5,1];
var temp = {};

for(let i=0;i<arr.length;i++){
    if(temp[arr[i]]==undefined){
       temp[arr[i]]=1;
    }else{
        temp[arr[i]]+=1;
    }
}

var max=0, maxEle;

for(const i in temp){
    if(temp[i]>max){
        max = temp[i];
        maxEle=i;
    }
}

console.log(`most occurred element is ${maxEle} and number of times is ${max}`);`

>>> arr = numpy.array(((2,2),(2,-2)))
>>> tuple(map(tuple, arr))
((2, 2), (2, -2))

• click fork button on original github project page
• clone your forked repository instead original
• push to it
• press Pull Requests button on your repository
• create it
• wait for original author to accept it

this worked like magic for me

Click on this Left-Bottom Manage Icon. Click Extensions or Short Cut Ctrl+Shift+X

Then Search in Extension with this key sentence Open In Default Browser. You will find this Extension. It is better to me.

Now right click on the html file and you will see Open in Default Browser or Short Cut Ctrl+1 to see the html file in browser.

The 500 code would normally indicate an error on the server, not anything with your code. Some thoughts

• Talk to the server developer for more info. You can't get more info directly.
• Verify your arguments into the call (values). Look for anything you might think could cause a problem for the server process. The process should not die and should return you a better code, but bugs happen there also.
• Could be intermittent, like if the server database goes down. May be worth trying at another time.

I would really recommend to:

• push only to the main repo

• make sure that main repo is a bare repo, in order to never have any problem with the main repo working tree being not in sync with its .git base. See "How to push a local git repository to another computer?"

• If you do have to make modification in the main (bare) repo, clone it (on the main server), do your modification and push back to it

In other words, keep a bare repo accessible both from the main server and the local computer, in order to have a single upstream repo from/to which to pull/pull.

In Java this would be System.in.read()

You cannot run .py files from JavaScript without the Python program like you cannot open .txt files without a text editor. But the whole thing becomes a breath with a help of a Web API Server (IIS in the example below).

1. Install python and create a sample file test.py

   import sys
   # print sys.argv[0] prints test.py
   # print sys.argv[1] prints your_var_1
   
   def hello():
       print "Hi" + " " + sys.argv[1]
   
   if __name__ == "__main__":
       hello()
   

2. Create a method in your Web API Server

   [HttpGet]
   public string SayHi(string id)
   {
       string fileName = HostingEnvironment.MapPath("~/Pyphon") + "\\" + "test.py";          
   
       Process p = new Process();
       p.StartInfo = new ProcessStartInfo(@"C:\Python27\python.exe", fileName + " " + id)
       {
           RedirectStandardOutput = true,
           UseShellExecute = false,
           CreateNoWindow = true
       };
       p.Start();
   
       return p.StandardOutput.ReadToEnd();                  
   }
   

3. And now for your JavaScript:

   function processSayingHi() {          
      var your_param = 'abc';
      $.ajax({
          url: '/api/your_controller_name/SayHi/' + your_param,
          type: 'GET',
          success: function (response) {
              console.log(response);
          },
          error: function (error) {
              console.log(error);
          }
       });
   }
   

Remember that your .py file won't run on your user's computer, but instead on the server.

use this code in Kotlin

fun makeCall(context: Context, mob: String) {
        try {
            val intent = Intent(Intent.ACTION_DIAL)

            intent.data = Uri.parse("tel:$mob")
            context.startActivity(intent)
        } catch (e: java.lang.Exception) {
            Toast.makeText(context,
                "Unable to call at this time", Toast.LENGTH_SHORT).show()

Either $(()) or $[] will work for computing the result of an arithmetic operation. You're using $() which is simply taking the string and evaluating it as a command. It's a bit of a subtle distinction. Hope this helps.

As tink pointed out in the comments on this answer, $[] is deprecated, and $(()) should be favored.

ALTER TABLE `table_name` AUTO_INCREMENT=1

Run following command:

mvn clean install -DskipTests=true

For just one run (from the unix shell prompt):

$ PORT=1234 node app.js

More permanently:

$ export PORT=1234
$ node app.js

In Windows:

set PORT=1234

In Windows PowerShell:

$env:PORT = 1234

simply pass the argument

attachtoroot = false

View view = inflater.inflate(R.layout.child_layout_to_merge, parent_layout, false);

Thank you, in PostgreSQL this works for boolean

SELECT

if you want to change the color dynamically:

1. Open de svg in a code editor
2. Add or rewrite the attribute of fill of every path to fill="currentColor"
3. Now, that svg will take the color of your font color so you can do something like:

svg {
    color : "red";
}

Simple:

st =  "abcdefghij"
st = st[:-1]

There is also another way that shows how it is done with steps:

list1 = "abcdefghij"
list2 = list(list1)
print(list2)
list3 = list2[:-1]
print(list3)

This is also a way with user input:

list1 = input ("Enter :")
list2 = list(list1)
print(list2)
list3 = list2[:-1]
print(list3)

To make it take away the last word in a list:

list1 = input("Enter :")
list2 = list1.split()
print(list2)
list3 = list2[:-1]
print(list3)

First you can give JavaScript's Date object (class) the new method 'fromYMD()' for converting MySQL's YMD date format into JavaScript format by splitting YMD format into components and using these date components:

Date.prototype.fromYMD=function(ymd)
{
  var t=ymd.split(/[- :]/); //split into components
  return new Date(t[0],t[1]-1,t[2],t[3]||0,t[4]||0,t[5]||0);
};

Now you can define your own object (funcion in JavaScript world):

function DateFromYMD(ymd)
{
  return (new Date()).fromYMD(ymd);
}

and now you can simply create date from MySQL date format;

var d=new DateFromYMD('2016-07-24');

According to lodash docs:

_.compact(_.map(array, fn))

Also you can filter out all nulls

Similar to this answer, though I used a temporary table instead:

CREATE TEMPORARY TABLE duplicates (
    SELECT payer_email
    FROM paypal_ipn_orders
    GROUP BY payer_email
    HAVING COUNT(id) > 1
);
SELECT id, payer_email
FROM paypal_ipn_orders AS p
INNER JOIN duplicates AS d ON d.payer_email=p.payer_email;

Just to add on Jacek's perfect solution. If you're trying to do this in Kotlin, it wont work immediately. Instead, you'll want to use this:

@Throws(IOException::class)
fun getSplashVideo(context: Context): File {
    val cacheFile = File(context.cacheDir, "splash_video")
    try {
        val inputStream = context.assets.open("splash_video")
        val outputStream = FileOutputStream(cacheFile)
        try {
            inputStream.copyTo(outputStream)
        } finally {
            inputStream.close()
            outputStream.close()
        }
    } catch (e: IOException) {
        throw IOException("Could not open splash_video", e)
    }
    return cacheFile
}

I used the below to solve this problem.

import org.apache.commons.lang.StringUtils;
StringUtils.capitalize(MyString);

Thanks to Ted Hopp for rightly pointing out that the question should have been TITLE CASE instead of modified CAMEL CASE.

Camel Case is usually without spaces between words.

.IMG files are ususally filesystems, not pictures. The easiest way to access them is to install VMWare, install Windows in VMWare, and then add the .img file as some kind of disk device (floppy, cdrom, hard disk). If you guess the right kind, Windows might be able to open it.

if (!s.match(/abc|def/g)) {
    alert("match");
}
else {
    alert("no match");
}

Overloading a method (or function) in C++ is the ability for functions of the same name to be defined as long as these methods have different signatures (different set of parameters). Method overriding is the ability of the inherited class rewriting the virtual method of the base class.

a) In overloading, there is a relationship between methods available in the same class whereas in overriding, there a is relationship between a superclass method and subclass method.

(b) Overloading does not block inheritance from the superclass whereas overriding blocks inheritance from the superclass.

(c) In overloading, separate methods share the same name whereas in overriding, subclass method replaces the superclass.

(d) Overloading must have different method signatures whereas overriding must have same signature.

try:

grep -n "text to find" file.ext | cut -f1 -d:

This XML file does not appear to have any style information associated with it. The document tree is shown below.

You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml instead of text/html and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.

In case of JSF/Facelets files which have the default extension of .xhtml, that can in turn happen if the HTTP request hasn't invoked the FacesServlet and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml file extension which is in your Firefox configuration apparently by default interpreted as text/xml.

You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern> of the FacesServlet as registered in webapp's web.xml, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf, then you need to open the page by /some.jsf instead of /some.xhtml. Alternatively, you can also just change the <url-pattern> to *.xhtml. This way you never need to fiddle with virtual URLs.

See also:

• JSF Facelets: Sometimes I see the URL is .jsf and sometimes .xhtml. Why?

Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.

Another tactic not yet mentioned is using appending to a list, and then converting the list to a tuple at the end:

mylist = []
for x in range(5):
    mylist.append(x)
mytuple = tuple(mylist)
print mytuple

returns

(0, 1, 2, 3, 4)

I sometimes use this when I have to pass a tuple as a function argument, which is often necessary for the numpy functions.

Maybe you need "sys." before:

select * from sys.registry$history;

This was how I solved it:

mysql> DROP DATABASE mydatabase;
ERROR 1010 (HY000): Error dropping database (can't rmdir '.\mydatabase', errno: 13)
mysql> 

I went to delete this directory: C:\...\UniServerZ\core\mysql\data\mydatabase.

mysql> DROP DATABASE mydatabase;
ERROR 1008 (HY000): Can't drop database 'mydatabase'; database doesn't exist

None of the about answers works for my case. I got the answer from here, and my SQL is:

INSERT INTO product (id, catalog_id, status_id, name, measure_unit_id, description, create_time)
VALUES (
  (SELECT id FROM (SELECT COALESCE(MAX(id),0)+1 AS id FROM product) AS temp),
  (SELECT id FROM product_catalog WHERE name="AppSys1"),
  (SELECT id FROM product_status WHERE name ="active"),
  "prod_name_x",
  (SELECT id FROM measure_unit WHERE name ="unit"),
  "prod_description_y",
  UNIX_TIMESTAMP(NOW())
)

if you want to have nullable property change your interface to this:

interface Person {
  name?:string | null,
  age?:string | null,
  gender?:string | null,
  occupation?:string | null,
 }

if being undefined is not the case you can remove question marks (?) from in front of the property names.

Note the "" at the beginning and at the end!

Run a program and pass a Long Filename

cmd /c write.exe "c:\sample documents\sample.txt"

Spaces in Program Path

cmd /c ""c:\Program Files\Microsoft Office\Office\Winword.exe""

Spaces in Program Path + parameters

cmd /c ""c:\Program Files\demo.cmd"" Parameter1 Param2

Spaces in Program Path + parameters with spaces

cmd /k ""c:\batch files\demo.cmd" "Parameter 1 with space" "Parameter2 with space""

Launch Demo1 and then Launch Demo2

cmd /c ""c:\Program Files\demo1.cmd" & "c:\Program Files\demo2.cmd""

CMD.exe (Command Shell)

Data for last month-

select count(distinct switch_id)
  from [email protected]
 where dealer_name =  'XXXX'
   and to_char(CREATION_DATE,'MMYYYY') = to_char(add_months(trunc(sysdate),-1),'MMYYYY');

All values of column A that are not present in column B will have a red background. Hope that it helps as starting point.

Sub highlight_missings()
Dim i As Long, lastA As Long, lastB As Long
Dim compare As Variant
Range("A:A").ClearFormats
lastA = Range("A65536").End(xlUp).Row
lastB = Range("B65536").End(xlUp).Row

For i = 2 To lastA
    compare = Application.Match(Range("a" & i), Range("B2:B" & lastB), 0)
        If IsError(compare) Then
            Range("A" & i).Interior.ColorIndex = 3
        End If
Next i
End Sub

Try this, it's working for me:

public bool IsValidEmailAddress(string s)
{
    if (string.IsNullOrEmpty(s))
        return false;
    else
    {
        var regex = new Regex(@"\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*");
        return regex.IsMatch(s) && !s.EndsWith(".");
    }
}

Using a jquery plugin I have adapted it to my needs adding customized options and creating a new plugin. You can find it here: https://github.com/david-dlc-cerezo/jquery-clearField

An example of a simple usage:

<script src='http://code.jquery.com/jquery-1.9.1.js'></script>
<script src='http://code.jquery.com/ui/1.10.3/jquery-ui.js'></script>
<script src='src/jquery.clearField.js'></script>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css">
<link rel="stylesheet" href="css/jquery.clearField.css">

<table>
    <tr>
        <td><input name="test1" id="test1" clas="test" type='text'></td>
        <td>Empty</td>
    </tr>
    <tr>
        <td><input name="test2" id="test2" clas="test" type='text' value='abc'></td>
        <td>Not empty</td>
    </tr>
</table>

<script>
    $('.test').clearField();
</script>

Obtaining something like this:

OSX Instructions

4. Open a terminal and cd into the package.
5. mkdir jdk-$version && cd jdk-$version
6. xar -xf ../JDK*.pkg
7. cd jdkTAB
8. tar zxf Payload
9. The Contents/Home folder contains the JDK

SYSDATE is an Oracle only function.

The ANSI standard defines current_date or current_timestamp which is supported by Postgres and documented in the manual:
http://www.postgresql.org/docs/current/static/functions-datetime.html#FUNCTIONS-DATETIME-CURRENT

(Btw: Oracle supports CURRENT_TIMESTAMP as well)

You should pay attention to the difference between current_timestamp, statement_timestamp() and clock_timestamp() (which is explained in the manual, see the above link)

This statement:

select up_time from exam where up_time like sysdate

Does not make any sense at all. Neither in Oracle nor in Postgres. If you want to get rows from "today", you need something like:

select up_time 
from exam 
where up_time = current_date

Note that in Oracle you would probably want trunc(up_time) = trunc(sysdate) to get rid of the time part that is always included in Oracle.
