You shouldn't use ${varName} when you're outside of strings, you should just use varName. Inside strings you use it like this; echo "this is a string ${someVariable}";. Infact you can place an general java expression inside of ${...}; echo "this is a string ${func(arg1, arg2)}.

I am getting similar errors recently because recent JDKs (and browsers, and the Linux TLS stack, etc.) refuse to communicate with some servers in my customer's corporate network. The reason of this is that some servers in this network still have SHA-1 certificates.

Please see: https://www.entrust.com/understanding-sha-1-vulnerabilities-ssl-longer-secure/ https://blog.qualys.com/ssllabs/2014/09/09/sha1-deprecation-what-you-need-to-know

If this would be your current case (recent JDK vs deprecated certificate encription) then your best move is to update your network to the proper encription technology.

In case that you should provide a temporal solution for that, please see another answers to have an idea about how to make your JDK trust or distrust certain encription algorithms:

How to force java server to accept only tls 1.2 and reject tls 1.0 and tls 1.1 connections

Anyway I insist that, in case that I have guessed properly your problem, this is not a good solution to the problem and that your network admin should consider removing these deprecated certificates and get a new one.

rawLapsData continues to point to the same array, even if you modify the contents of the array (e.g., add items, remove items, change an item).

During change detection, when Angular checks components' input properties for change, it uses (essentially) === for dirty checking. For arrays, this means the array references (only) are dirty checked. Since the rawLapsData array reference isn't changing, ngOnChanges() will not be called.

I can think of two possible solutions:

1. Implement ngDoCheck() and perform your own change detection logic to determine if the array contents have changed. (The Lifecycle Hooks doc has an example.)

2. Assign a new array to rawLapsData whenever you make any changes to the array contents. Then ngOnChanges() will be called because the array (reference) will appear as a change.

In your answer, you came up with another solution.

Repeating some comments here on the OP:

I still don't see how laps can pick up on the change (surely it must be using something equivalent to ngOnChanges() itself?) while map can't.

• In the laps component your code/template loops over each entry in the lapsData array, and displays the contents, so there are Angular bindings on each piece of data that is displayed.
• Even when Angular doesn't detect any changes to a component's input properties (using === checking), it still (by default) dirty checks all of the template bindings. When any of those change, Angular will update the DOM. That's what you are seeing.
• The maps component likely doesn't have any bindings in its template to its lapsData input property, right? That would explain the difference.

Note that lapsData in both components and rawLapsData in the parent component all point to the same/one array. So even though Angular doesn't notice any (reference) changes to the lapsData input properties, the components "get"/see any array contents changes because they all share/reference that one array. We don't need Angular to propagate these changes, like we would with a primitive type (string, number, boolean). But with a primitive type, any change to the value would always trigger ngOnChanges() – which is something you exploit in your answer/solution.

As you probably figured out by now object input properties have the same behavior as array input properties.

I did manage to finally display a window on the lock screen with the use of TYPE_SYSTEM_OVERLAY instead of TYPE_KEYGUARD_DIALOG. This works as expected and adds the window on the lock screen.

The problem with this is that the window is added on top of everything it possibly can. That is, the window will even appear on top of your keypad/pattern lock in case of secure lock screens. In the case of an unsecured lock screen, it will appear on top of the notification tray if you open it from the lock screen.

For me, that is unacceptable. I hope that this may help anybody else facing this problem.

Actually you can still have a Map with the original keys after converting to array with Array.from. That's possible by returning an array, where the first item is the key, and the second is the transformed value.

const originalMap = new Map([
  ["thing1", 1], ["thing2", 2], ["thing3", 3]
]);

const arrayMap = Array.from(originalMap, ([key, value]) => {
    return [key, value + 1]; // return an array
});

const alteredMap = new Map(arrayMap);

console.log(originalMap); // Map { 'thing1' => 1, 'thing2' => 2, 'thing3' => 3 }
console.log(alteredMap);  // Map { 'thing1' => 2, 'thing2' => 3, 'thing3' => 4 }

If you don't return that key as the first array item, you loose your Map keys.

It seems the button you are invoking is not in the layout you are using in setContentView(R.layout.your_layout) Check it.

what worked for me is converting the props.data to an array using data = Array.from(props.data); then I could use the data.map() function

For API level >= 28 available attribute android:dialogCornerRadius . To support previous API versions need use

<style name="RoundedDialog" parent="Theme.AppCompat.Light.Dialog.Alert">

I had the very same problem and then I realized that programming in NodeJS is actually different than Python or Java as its based on JavaScript. I'll try to use simple concepts as there may be a few new folks that would be interested or may come to this question.

Let's look at the following code :

var http = require('http'); // (1)
exports.handler = function(event, context) {
  console.log('start request to ' + event.url)
  http.get(event.url,  // (2)
  function(res) {  //(3)
    console.log("Got response: " + res.statusCode);
    context.succeed();
  }).on('error', function(e) {
    console.log("Got error: " + e.message);
    context.done(null, 'FAILURE');
  });

  console.log('end request to ' + event.url); //(4)
}

Whenever you make a call to a method in http package (1) , it is created as event and this event gets it separate event. The 'get' function (2) is actually the starting point of this separate event.

Now, the function at (3) will be executing in a separate event, and your code will continue it executing path and will straight jump to (4) and finish it off, because there is nothing more to do.

But the event fired at (2) is still executing somewhere and it will take its own sweet time to finish. Pretty bizarre, right ?. Well, No it is not. This is how NodeJS works and its pretty important you wrap your head around this concept. This is the place where JavaScript Promises come to help.

You can read more about JavaScript Promises here. In a nutshell, you would need a JavaScript Promise to keep the execution of code inline and will not spawn new / extra threads.

Most of the common NodeJS packages have a Promised version of their API available, but there are other approaches like BlueBirdJS that address the similar problem.

The code that you had written above can be loosely re-written as follows.

'use strict';
console.log('Loading function');
var rp = require('request-promise');
exports.handler = (event, context, callback) => {    

    var options = {
    uri: 'https://httpbin.org/ip',
    method: 'POST',
    body: {

    },
    json: true 
};


    rp(options).then(function (parsedBody) {
            console.log(parsedBody);
        })
        .catch(function (err) {
            // POST failed... 
            console.log(err);
        });

    context.done(null);
};

Please note that the above code will not work directly if you will import it in AWS Lambda. For Lambda, you will need to package the modules with the code base too.

I needed to use a link with onLoad attribute in my head where div is not allowed so this caused me significant pain. My current workaround is to close the original script tag, do what I need to do, then open script tag (to be closed by the original). Hope this might help someone who has absolutely no other choice:

<script dangerouslySetInnerHTML={{ __html: `</script>
   <link rel="preload" href="https://fonts.googleapis.com/css?family=Open+Sans" as="style" onLoad="this.onload=null;this.rel='stylesheet'" crossOrigin="anonymous"/>
<script>`,}}/>

If you're using getApplicationContext() as Context in Activity for the dialog like this

Dialog dialog = new Dialog(getApplicationContext());

then use YourActivityName.this

Dialog dialog = new Dialog(YourActivityName.this);

I found the SVG marker/icon to be best one yet. It is very flexible and allows any color you like. You can customize the entire icon without much of a hassle:

function createIcon(markerColor) {
  /* ...Code ommitted ... */

  return new L.DivIcon.SVGIcon({
            color: markerColor,
            iconSize: [15,30],
            circleRatio: 0.35
  });
}

See how the Code is working here:

After calling the Async task, the async task runs in the background. that is desirable. Now, this Async task has a progress dialog which is attached to the Activity, if you ask how to see the code:

pDialog = new ProgressDialog(CLASS.this);

You are passing the Class.this as context to the argument. So the Progress dialog is still attached to the activity.

Now consider the scenario: If we try to finish the activity using the finish() method, while the async task is in progress, is the point where you are trying to access the Resource attached to the activity ie the progress bar when the activity is no more there.

Hence you get:

java.lang.IllegalArgumentException: View not attached to the window manager

Solution to this:

1) Make sure that the Dialog box is dismissed or canceled before the activity finishes.

2) Finish the activity, only after the dialog box is dismissed, that is the async task is over.

In my case this error appeared when I asigned to both dynamic created controls (combobox), same created control from other class.

//dynamic created controls
ComboBox combobox1 = ManagerControls.myCombobox1;
...some events

ComboBox combobox2 = ManagerControl.myComboBox2;
...some events

.

//method in constructor
public static void InitializeDynamicControls()
{
     ComboBox cb = new ComboBox();
     cb.Background = new SolidColorBrush(Colors.Blue);
     ...
     cb.Width = 100;
     cb.Text = "Select window";
        
     ManagerControls.myCombobox1 = cb;
     ManagerControls.myComboBox2 = cb; // <-- error here
}

Solution: create another ComboBox cb2 and assign it to ManagerControls.myComboBox2.

I hope I helped someone.

Since Date implements Comparable<Date>, it is as easy as:

date1.compareTo(date2);

As the Comparable contract stipulates, it will return a negative integer/zero/positive integer if date1 is considered less than/the same as/greater than date2 respectively (ie, before/same/after in this case).

Note that Date has also .after() and .before() methods which will return booleans instead.

Here's a fixed version of it: http://play.golang.org/p/w2ZcOzGHKR

The biggest fix that was needed is when Unmarshalling an array, that property needs to be an array/slice in the struct as well.

For example:

{ "things": ["a", "b", "c"] }

Would Unmarshal into a:

type Item struct {
    Things []string
}

And not into:

type Item struct {
    Things string
}

The other thing to watch out for when Unmarshaling is that the types line up exactly. It will fail when Unmarshalling a JSON string representation of a number into an int or float field -- "1" needs to Unmarshal into a string, not into an int like we saw with ShippingAdditionalCost int

just this ?

<style name="Theme.AppCompat.Light.NoActionBar.FullScreen">
    <item name="android:windowFullscreen">true</item>
</style>

Wanny is correct. The && operator doesn't work in HTML. With Angular, you must use the double pipes (||)for multiple conditions.

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 try this it solved.

 AlertDialog.Builder builder = new AlertDialog.Builder(
                   this);
            builder.setCancelable(true);
            builder.setTitle("Opss!!");

            builder.setMessage("You Don't have anough coins to withdraw. ");
            builder.setMessage("Please read the Withdraw rules.");
            builder.setInverseBackgroundForced(true);
            builder.setPositiveButton("OK",
                    (dialog, which) -> dialog.dismiss());
            builder.create().show();

Just had the same problem here. In my case, the bat files had space " " After getting rid of spaces from filename and change into underscore, bat file worked

sample before it wont start

"x:\Update & pull.bat"

This is good Angular plugin for uploading files, and its free!

angular file upload

I was getting this error after adding the include files and linking the library. It was because the lib was built with non-unicode and my application was unicode. Matching them fixed it.

Maybe this will help

Great solutions here, just one more option that taking into consideration handling of null values:

Map<String,Object> map = new HashMap<>();

Map<String,String> stringifiedMap = map.entrySet().stream()
             .filter(m -> m.getKey() != null && m.getValue() !=null)
             .collect(Collectors.toMap(Map.Entry::getKey, e -> (String)e.getValue()));

create a folder inside htdocs, place your website there, access it via localhost or Internal IP (if you're behind a router) - check out this video demo here

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

    var show_button = 'Show', hide_button = 'Hide';
    function showhide() {
        var div = document.getElementById( "hide_show" );
        var showhide = document.getElementById( "showhide" );

If that message is bother you, You need run Visual Studio with administrative rights to apply this direction on Visual Studio.

Tools-> Options-> Debugging-> Symbols and select check in a box "Microsoft Symbol Servers", mark load all modules then click Load all Symbols.

Everything else Visual Studio will do it for you, and you will have this message under Debug in Output window "Native' has exited with code 0 (0x0)"

A module is a file containing Python definitions and statements. The file name is the module name with the suffix .py

create hello.py then write the following function as its content:

def helloworld():
   print "hello"

Then you can import hello:

>>> import hello
>>> hello.helloworld()
'hello'
>>>

To group many .py files put them in a folder. Any folder with an __init__.py is considered a module by python and you can call them a package

|-HelloModule
  |_ __init__.py
  |_ hellomodule.py

You can go about with the import statement on your module the usual way.

For more information, see 6.4. Packages.

For Sublime Text Editor

Indentation Error generally occurs when the code contains a mix of both tabs and spaces for indentation. I have got a very nice solution to correct it, just open your code in a sublime text editor and find 'Tab Size' in the bottom right corner of Sublime Text Editor and click it. Now select either

'Convert Indentation to Spaces'

OR

'Convert Indentation to Tabs'

Your code will work in either case.

Additionally, if you want Sublime text to do it automatically for you for every code you can update the Preference settings as below:-

Sublime Text menu > Preferences > Settings - Syntax Specific :

Python.sublime-settings

{
    "tab_size": 4,
    "translate_tabs_to_spaces": true
}

If you just want to have screenshot of a div, you can do it like this

html2canvas($('#div'), {
  onrendered: function(canvas) {
    var img = canvas.toDataURL()
    window.open(img);
  }
});

 private void requestFocus(View view) {
        if (view.requestFocus()) {
            getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
        }
    }

//Function Call
requestFocus(yourEditetxt);

To sum with decimal use this:

In the javascript change parseInt with parseFloat and add this line tot.toFixed(2); for this result:

    function findTotal(){
    var arr = document.getElementsByName('qty');
    var tot=0;
    for(var i=0;i<arr.length;i++){
        if(parseFloat(arr[i].value))
            tot += parseFloat(arr[i].value);
    }
    document.getElementById('total').value = tot;
    tot.toFixed(2);
}

Use step=".01" min="0" type="number" in the input filed

Qty1 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty1"/><br>
Qty2 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty2"/><br>
Qty3 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty3"/><br>
Qty4 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty4"/><br>
Qty5 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty5"/><br>
Qty6 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty6"/><br>
Qty7 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty7"/><br>
Qty8 : <input onblur="findTotal()" step=".01" min="0" type="number" name="qty" id="qty8"/><br>
<br><br>
Total : <input type="number" step=".01" min="0" name="total" id="total"/>

i solved this in a shorter fashion.

Dim marray() as variant, array2() as variant, YY ,ZZ as integer
YY=1
ZZ=1

Redim marray(1 to 1000, 1 to 10)
Do while ZZ<100 ' this is populating the first array
marray(ZZ,YY)= "something"
ZZ=ZZ+1
YY=YY+1 
Loop
'this part is where you store your array in another then resize and restore to original
array2= marray
Redim marray(1 to ZZ-1, 1 to YY)
marray = array2

Your BlockID function uses the undefined variable images, which will lead to an error. Also, you should not use an Array here - JavaScripts key-value-maps are plain objects:

function BlockID() {
    return {
        "s": "Images/Block_01.png",
        "g": "Images/Block_02.png",
        "C": "Images/Block_03.png",
        "d": "Images/Block_04.png"
    };
}

An "incomplete class" is one declared but not defined. E.g.

class Wielrenner;

as opposed to

class Wielrenner
{
    /* class members */
};

You need to #include "wielrenner.h" in dokter.ccp

 @Override
    protected void onPostExecute(final Boolean success) {
        mProgressDialog.dismiss();
        mProgressDialog = null;

setting the value null works for me

The first problem is that your query string is wrong:

I think this: "INSERT INTO employee(hans,germany) values(?,?)" should be like this: "INSERT INTO employee(name,country) values(?,?)"

The other problem is that you have a parameterized PreparedStatement and you don't set the parameters before running it.

You should add these to your code:

String inserting = "INSERT INTO employee(name,country) values(?,?)";
System.out.println("insert " + inserting);//
PreparedStatement ps = con.prepareStatement(inserting); 
ps.setString(1,"hans"); // <----- this
ps.setString(2,"germany");// <---- and this
ps.executeUpdate();

Make sure that you do not put into Intent object data of large size. In my case I was adding String 500k size and then starting another activity. It always failed with this exception. I avoided sharing data between activities by using static variables of activities - you don't have to send them to Intent and then pulling from it.

What I had:

String html = new String();//some string of 500K data.
Intent intent = new Intent(MainActivity.this, PageWebView.class);
//this is workaround - I just set static variable and then access it from another    activity.
MainActivity.htmlBody = timelineDb.getHTMLBodyForTweet(tweet);
//This line was present and it actually failed with the same exception you had.
//intent.putExtra("com.gladimdim.offtie.webview", html);

Try something like this inside ThisOutlookSession:

Private Sub Application_NewMail()
    Call Your_main_macro
End Sub

My outlook vba just fired when I received an email and had that application event open.

Edit: I just tested a hello world msg box and it ran after being called in the application_newmail event when an email was received.

Since @Etienne asked how to do this without melting the data (which in general is the preferred method, but I recognize there may be some cases where that is not possible), I present the following alternative.

Start with a subset of the original data:

datos <-
structure(list(fecha = structure(c(1317452400, 1317538800, 1317625200, 
1317711600, 1317798000, 1317884400, 1317970800, 1318057200, 1318143600, 
1318230000, 1318316400, 1318402800, 1318489200, 1318575600, 1318662000, 
1318748400, 1318834800, 1318921200, 1319007600, 1319094000), class = c("POSIXct", 
"POSIXt"), tzone = ""), TempMax = c(26.58, 27.78, 27.9, 27.44, 
30.9, 30.44, 27.57, 25.71, 25.98, 26.84, 33.58, 30.7, 31.3, 27.18, 
26.58, 26.18, 25.19, 24.19, 27.65, 23.92), TempMedia = c(22.88, 
22.87, 22.41, 21.63, 22.43, 22.29, 21.89, 20.52, 19.71, 20.73, 
23.51, 23.13, 22.95, 21.95, 21.91, 20.72, 20.45, 19.42, 19.97, 
19.61), TempMin = c(19.34, 19.14, 18.34, 17.49, 16.75, 16.75, 
16.88, 16.82, 14.82, 16.01, 16.88, 17.55, 16.75, 17.22, 19.01, 
16.95, 17.55, 15.21, 14.22, 16.42)), .Names = c("fecha", "TempMax", 
"TempMedia", "TempMin"), row.names = c(NA, 20L), class = "data.frame")

You can get the desired effect by (and this also cleans up the original plotting code):

ggplot(data = datos, aes(x = fecha)) +
  geom_line(aes(y = TempMax, colour = "TempMax")) +
  geom_line(aes(y = TempMedia, colour = "TempMedia")) +
  geom_line(aes(y = TempMin, colour = "TempMin")) +
  scale_colour_manual("", 
                      breaks = c("TempMax", "TempMedia", "TempMin"),
                      values = c("red", "green", "blue")) +
  xlab(" ") +
  scale_y_continuous("Temperatura (C)", limits = c(-10,40)) + 
  labs(title="TITULO")

The idea is that each line is given a color by mapping the colour aesthetic to a constant string. Choosing the string which is what you want to appear in the legend is the easiest. The fact that in this case it is the same as the name of the y variable being plotted is not significant; it could be any set of strings. It is very important that this is inside the aes call; you are creating a mapping to this "variable".

scale_colour_manual can now map these strings to the appropriate colors. The result is

In some cases, the mapping between the levels and colors needs to be made explicit by naming the values in the manual scale (thanks to @DaveRGP for pointing this out):

ggplot(data = datos, aes(x = fecha)) +
  geom_line(aes(y = TempMax, colour = "TempMax")) +
  geom_line(aes(y = TempMedia, colour = "TempMedia")) +
  geom_line(aes(y = TempMin, colour = "TempMin")) +
  scale_colour_manual("", 
                      values = c("TempMedia"="green", "TempMax"="red", 
                                 "TempMin"="blue")) +
  xlab(" ") +
  scale_y_continuous("Temperatura (C)", limits = c(-10,40)) + 
  labs(title="TITULO")

(giving the same figure as before). With named values, the breaks can be used to set the order in the legend and any order can be used in the values.

ggplot(data = datos, aes(x = fecha)) +
  geom_line(aes(y = TempMax, colour = "TempMax")) +
  geom_line(aes(y = TempMedia, colour = "TempMedia")) +
  geom_line(aes(y = TempMin, colour = "TempMin")) +
  scale_colour_manual("", 
                      breaks = c("TempMedia", "TempMax", "TempMin"),
                      values = c("TempMedia"="green", "TempMax"="red", 
                                 "TempMin"="blue")) +
  xlab(" ") +
  scale_y_continuous("Temperatura (C)", limits = c(-10,40)) + 
  labs(title="TITULO")

In my case, I was defining a bean and autowiring it in the constructor of the same class file.

@SpringBootApplication
public class MyApplication {
    private MyBean myBean;

    public MyApplication(MyBean myBean) {
        this.myBean = myBean;
    }

    @Bean
    public MyBean myBean() {
        return new MyBean();
    }
}

My solution was to move the bean definition to another class file.

@Configuration
public CustomConfig {
    @Bean
    public MyBean myBean() {
        return new MyBean();
    }
}

Hi I hope this will help:

 private PowerManager mPowerManager;
 private PowerManager.WakeLock mWakeLock;

 public void turnOnScreen(){
     // turn on screen
     Log.v("ProximityActivity", "ON!");
     mWakeLock = mPowerManager.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "tag");
     mWakeLock.acquire();
}

 @TargetApi(21) //Suppress lint error for PROXIMITY_SCREEN_OFF_WAKE_LOCK
 public void turnOffScreen(){
     // turn off screen
     Log.v("ProximityActivity", "OFF!");
     mWakeLock = mPowerManager.newWakeLock(PowerManager.PROXIMITY_SCREEN_OFF_WAKE_LOCK, "tag");
     mWakeLock.acquire();
}

After execute the thread, add these two line of code, and that will solve the issue.

Looper.loop();
Looper.myLooper().quit();

Simply Use EditText.setFocusable(false); in activity

or use in xml

android:focusable="false"

Its Working in Pie OS Use this

    @Override
    protected void onCreate() {
        super.onCreate();
        //setNotificationBadge();

        if (android.os.Build.VERSION.SDK_INT >= 9) {
            StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
            StrictMode.setThreadPolicy(policy);
        }

    }

        userImage.setTitle("Login");

        runOnUiThread(new Runnable() {
            @Override

This is an old question but it might help someone.

@Override
protected void onUserLeaveHint()
{
    Log.d("onUserLeaveHint","Home button pressed");
    super.onUserLeaveHint();
}

According to the documentation, the onUserLeaveHint() method is called when the user clicks the home button OR when something interrupts your application (like an incoming phone call).

This works for me.. :)

use this method before show

public static ViewGroup getActivityFirstLayout(Context ctx)
{
    return (ViewGroup)((ViewGroup) ActivityMaster.getActivity(ctx).findViewById(android.R.id.content)).getChildAt(0);
}

private boolean activityIsOk(Activity activity)
{
    boolean s1 = !(activity == null || activity.isFinishing());

    if(s1)
    {
        View v = LayoutMaster.getActivityFirstLayout(activity);
        return v.isShown() && ViewCompat.isLaidOut(v);
    }

    return false;
}

Your class:

class name {
  public:
    string first;
    string last;

  name() { }  //Default constructor.

  name(string a, string b){
    first = a;
    last = b;
  }
};

Has an explicit constructor that requires two string parameters. Classes with no constructor written explicitly get default constructors taking no parameters. Adding the explicit one stopped the compiler from generating that default constructor for you.

So, if you wish to make an array of uninitialized objects, add a default constructor to your class so the compiler knows how to create them without providing those two string parameters - see the commented line above.

Your PersonSheets has a property int Id, Id isn't in the post, so modelbinding fails. Make Id nullable (int?) or send atleast Id = 0 with the POst .

fun Activity.setStatusBarVisibility(isVisible: Boolean) {
    //see details https://developer.android.com/training/system-ui/immersive
    if (isVisible) {
        window.decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN)
        window.decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN)
    } else {
        window.decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                or View.SYSTEM_UI_FLAG_FULLSCREEN)
    }
}

You can continue to use getApplicationContext(), but before use, you should add this flag: dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT), and the error will not show.

And don't forget to add permission:

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

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Mikhail,

The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.

Good luck with your implementation.

You need to wrap button click handler to match the pattern

public void klik(object sender, EventArgs e)

UPDATE 2

@Override
    protected void onResume() {
        super.onResume();
        mUserNameEdit.requestFocus();

        mUserNameEdit.postDelayed(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                InputMethodManager keyboard = (InputMethodManager)
                getSystemService(Context.INPUT_METHOD_SERVICE);
                keyboard.showSoftInput(mUserNameEdit, 0);
            }
        },200); //use 300 to make it run when coming back from lock screen
    }

I tried very hard and found out a solution ... whenever a new activity starts then keyboard cant open but we can use Runnable in onResume and it is working fine so please try this code and check...

UPDATE 1

add this line in your AppLogin.java

mUserNameEdit.requestFocus();

and this line in your AppList.java

listview.requestFocus()'

after this check your application if it is not working then add this line in your AndroidManifest.xml file

<activity android:name=".AppLogin" android:configChanges="keyboardHidden|orientation"></activity>
<activity android:name=".AppList" android:configChanges="keyboard|orientation"></activity>

ORIGINAL ANSWER

 InputMethodManager imm = (InputMethodManager)this.getSystemService(Service.INPUT_METHOD_SERVICE);

for hide keyboard

 imm.hideSoftInputFromWindow(ed.getWindowToken(), 0); 

for show keyboard

 imm.showSoftInput(ed, 0);

for focus on EditText

 ed.requestFocus();

where ed is EditText

To achieve this feat, define a outer linear layout with a weightSum={amount of weight to distribute}.

it defines the maximum weight sum. If unspecified, the sum is computed by adding the layout_weight of all of the children. This can be used for instance to give a single child 50% of the total available space by giving it a layout_weight of 0.5 and setting the weightSum to 1.0.Another example would be set weightSum=2, and if the two children set layout_weight=1 then each would get 50% of the available space.

WeightSum is dependent on the amount of children in the parent layout.

Display display = getActivity().getWindowManager().getDefaultDisplay(); 
int screenWidth = display.getWidth();
int screenHeight = display.getHeight();
Log.d("Tag", "Getting Width >> " + screenWidth);
Log.d("Tag", "Getting Height >> " + screenHeight);

This worked properly in my application

Get Screen Width and Height in terms of DP with some good decoration:

Step 1: Create interface

public interface ScreenInterface {

   float getWidth();

   float getHeight();

}

Step 2: Create implementer class

public class Screen implements ScreenInterface {
    private Activity activity;

    public Screen(Activity activity) {
        this.activity = activity;
    }

    private DisplayMetrics getScreenDimension(Activity activity) {
        DisplayMetrics displayMetrics = new DisplayMetrics();
        activity.getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
        return displayMetrics;
    }

    private float getScreenDensity(Activity activity) {
        return activity.getResources().getDisplayMetrics().density;
    }

    @Override
    public float getWidth() {
        DisplayMetrics displayMetrics = getScreenDimension(activity);
        return displayMetrics.widthPixels / getScreenDensity(activity);
    }

    @Override
    public float getHeight() {
        DisplayMetrics displayMetrics = getScreenDimension(activity);
        return displayMetrics.heightPixels / getScreenDensity(activity);
    }
} 

Step 3: Get width and height in activity:

Screen screen = new Screen(this); // Setting Screen
screen.getWidth();
screen.getHeight();

You can also define Theme in android manifest file for not display Title bar..

You just define theme android:theme="@android:style/Theme.Light.NoTitleBar" in activity where u dont want to display title bar

Example:-

    <uses-sdk android:minSdkVersion="4"android:targetSdkVersion="4" />
<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".splash"
              android:label="@string/app_name" android:screenOrientation="portrait"
              android:theme="@android:style/Theme.Light.NoTitleBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

<activity android:name="main" android:screenOrientation="portrait" android:theme="@android:style/Theme.Light.NoTitleBar"></activity>

If you are outside of the Activity then you need to use in your function "NameOfMyActivity.this" as Activity activity, example:

public static void showDialog(Activity activity) {
        AlertDialog.Builder builder = new AlertDialog.Builder(activity);
        builder.setMessage("Your Message")
        .setPositiveButton("Yes", dialogClickListener)
        .setNegativeButton("No", dialogClickListener).show();
}


//Outside your Activity
showDialog(NameOfMyActivity.this);

In Python3 iteritems() is no longer supported

Use .items

for field, possible_values in fields.items():
    print(field, possible_values)

Use String.Format:

string title1 = "Sample Title One";
string element1 = "Element One";
string format = "{0,-20} {1,-10}";

string result = string.Format(format, title1, element1);
//or you can print to Console directly with
//Console.WriteLine(format, title1, element1);

In the format {0,-20} means the first argument has a fixed length 20, and the negative sign guarantees the string is printed from left to right.

Here's a simple solution, your problem is that your whole application closes when your login form closes right? If so, then go to your projects properties and on the Application Tab change the shutdown mode to "When last form closes" that way you can use Me.close without closing the whole program

to change pro-grammatically use :

imgview.setScaleType(ScaleType.FIT_XY);

OR

to change from xml use:

 android:scaleType="fitXY"

Well try my code, atleast it gives you a string as overlay, you can very well replace it with a button or an image. You wont believe this is my first ever android app LOL. Anyways if you are more experienced with android apps than me, please try

• changing parameters 2 and 3 in "new WindowManager.LayoutParams"
• try some different event approach

http://developer.android.com/reference/android/content/Context.html#BIND_ABOVE_CLIENT

public static final int BIND_ABOVE_CLIENT -- Added in API level 14

Flag for bindService(Intent, ServiceConnection, int): indicates that the client application binding to this service considers the service to be more important than the app itself. When set, the platform will try to have the out of memory killer kill the app before it kills the service it is bound to, though this is not guaranteed to be the case.

Other flags of the same group are: BIND_ADJUST_WITH_ACTIVITY, BIND_AUTO_CREATE, BIND_IMPORTANT, BIND_NOT_FOREGROUND, BIND_WAIVE_PRIORITY.

Note that the meaning of BIND_AUTO_CREATE has changed in ICS, and old applications that don't specify BIND_AUTO_CREATE will automatically have the flags BIND_WAIVE_PRIORITY and BIND_ADJUST_WITH_ACTIVITY set for them.

If you are dealing with LiveData, when updating value instead of using liveData.value = someValue try to do liveData.postValue(someValue)

I had the same problem while using a button to sync a list from the server: 1) I click the button 2) A progress dialog shows up while dowloading the list from server 3) I turn the device to another orientation 4) java.lang.IllegalArgumentException: View not attached to window manager on postExecute() of the AsyncTask during progress.dismiss().

As I tried the fix I figured that even if the problem doesn't occur my list wasn't showing all items.

I figured that what I wanted was for the AsyncTask to finish (and dismiss the dialog) before the activity beign destroyed, so I made the asynctask object an attribute and overrided the onDestroy() method.

If the asynctask takes a lot of time the user maybe will feel that the device is slow, but I think that's the price he pays for trying to change the device orientation while the progress dialog is showing up. And even if it takes some time the app doesn't crash.

private AsyncTask<Boolean, Void, Boolean> atask;

@Override
protected void onDestroy() {
    if (atask!=null)
        try {
            atask.get();
        } catch (InterruptedException e) {
        } catch (ExecutionException e) {
        }
    super.onDestroy();
}

For nested dialogs this issue is very common, It works when

AlertDialog.Builder mDialogBuilder = new AlertDialog.Builder(MyActivity.this);

is used instead of

mDialogBuilder = new AlertDialog.Builder(getApplicationContext);

this alternative.

I do it with this simple examps

jQuery

$('.map').click(function(){
    $(this).find('iframe').addClass('clicked')
    }).mouseleave(function(){
    $(this).find('iframe').removeClass('clicked')
});

CSS

.map {
    width: 100%; 
}
.map iframe {
    width: 100%;
    display: block;
    pointer-events: none;
    position: relative; /* IE needs a position other than static */
}
.map iframe.clicked {
    pointer-events: auto;
}

Or use the gmap options

function init() { 
    var mapOptions = {  
        scrollwheel: false, 

Why not try catch, like this:

protected void onPostExecute(Object result) {
        try {
            if ((mDialog != null) && mDialog.isShowing()) {
                mDialog.dismiss();
            }
        } catch (Exception ex) {
            Log.e(TAG, ex.getMessage(), ex);
        }
    }

Suppose you declared HashMap as :-

HashMap<Character,Integer> hs = new HashMap<>();

Then,key in map is of type Character data type and value of int type.Now,to get value corresponding to key irrespective of type of key,value type, syntax is :-

    char temp = 'a';
    if(hs.containsKey(temp)){
`       int val = hs.get(temp); //val is the value corresponding to key temp
    }

So, according to your question you want to get string value corresponding to a key.For this, just declare HashMap as HashMap<"datatype of key","datatype of value" hs = new HashMap<>(); Using this will make your code cleaner and also you don't have to convert the result of hs.get("my_code") to string as by default it returns value of string if at entry time one has kept value as a string.

For Activities shown within TabActivities use getParent()

final AlertDialog.Builder builder = new AlertDialog.Builder(getParent());

instead of

final AlertDialog.Builder builder = new AlertDialog.Builder(this);

You may add this values to your style android:windowMinWidthMajor and android:windowMinWidthMinor

<style name="Theme_Dialog" parent="android:Theme.Holo.Dialog">
    ...
    <item name="android:windowMinWidthMajor">97%</item>
    <item name="android:windowMinWidthMinor">97%</item>
</style>

Count Normal arrya or object

count($object_or_array); 

Count multidimensional arrya or object

count($object_or_array, 1); // 1 for  multidimensional array count, 0 for Default

Tried to implement jfelectron's solution because it is a "rock-solid solution to these issues that conforms with the 'Android Way' of things" but it took some time to look up and put together all the elements mentioned. Ended up with this slightly different, and I think more elegant, solution posted here in it's entirety.

Uses an IntentService fired from an activity to perform the long running task on a separate thread. The service fires back sticky Broadcast Intents to the activity which update the dialog. The Activity uses showDialog(), onCreateDialog() and onPrepareDialog() to eliminate the need to have persistent data passed in the application object or the savedInstanceState bundle. This should work no matter how your application is interrupted.

Activity Class:

public class TesterActivity extends Activity {
private ProgressDialog mProgressDialog;
private static final int PROGRESS_DIALOG = 0;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Button b = (Button) this.findViewById(R.id.test_button);
    b.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            buttonClick();
        }
    });
}

private void buttonClick(){
    clearPriorBroadcast();
    showDialog(PROGRESS_DIALOG);
    Intent svc = new Intent(this, MyService.class);
    startService(svc);
}

protected Dialog onCreateDialog(int id) {
    switch(id) {
    case PROGRESS_DIALOG:
        mProgressDialog = new ProgressDialog(TesterActivity.this);
        mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        mProgressDialog.setMax(MyService.MAX_COUNTER);
        mProgressDialog.setMessage("Processing...");
        return mProgressDialog;
    default:
        return null;
    }
}

@Override
protected void onPrepareDialog(int id, Dialog dialog) {
    switch(id) {
    case PROGRESS_DIALOG:
        // setup a broadcast receiver to receive update events from the long running process
        IntentFilter filter = new IntentFilter();
        filter.addAction(MyService.BG_PROCESS_INTENT);
        registerReceiver(new MyBroadcastReceiver(), filter);
        break;
    }
}

public class MyBroadcastReceiver extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.hasExtra(MyService.KEY_COUNTER)){
            int count = intent.getIntExtra(MyService.KEY_COUNTER, 0);
            mProgressDialog.setProgress(count);
            if (count >= MyService.MAX_COUNTER){
                dismissDialog(PROGRESS_DIALOG);
            }
        }
    }
}

/*

 */
private void clearPriorBroadcast(){
    Intent broadcastIntent = new Intent();
    broadcastIntent.setAction(MyService.BG_PROCESS_INTENT);
    sendStickyBroadcast(broadcastIntent);
}}

IntentService Class:

public class MyService extends IntentService {

public static final String BG_PROCESS_INTENT = "com.mindspiker.Tester.MyService.TEST";
public static final String KEY_COUNTER = "counter";
public static final int MAX_COUNTER = 100;

public MyService() {
  super("");
}

@Override
protected void onHandleIntent(Intent intent) {
    for (int i = 0; i <= MAX_COUNTER; i++) {
        Log.e("Service Example", " " + i);
        try {
            Thread.sleep(100);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        Intent broadcastIntent = new Intent();
        broadcastIntent.setAction(BG_PROCESS_INTENT);
        broadcastIntent.putExtra(KEY_COUNTER, i);
        sendStickyBroadcast(broadcastIntent);
    }
}}

Manifest file entries:

Lambdas are deeply linked to functional programming style in general. The idea that you can solve problems by applying a function to some data, and merging the results, is what google uses to implement most of its algorithms.

Programs written in functional programming style, are easily parallelized and hence are becoming more and more important with modern multi-core machines. So in short, NO you should not forget them.

The problem in my case is that the Gemfile.lock file had a BUNDLED_WITH version of 1.16.1 and gem install bundler installed version 2.0.1, so there was a version mismatch when looking to right the folder

gem install bundler -v 1.16.1 fixed it

Of course, you can also change your Gemfile.lock's BUNDLED_WITH with last bundler version and use recent software, as Sam3000 suggests

Have you tried the exec command within the Runtime class?

Runtime.getRuntime().exec("java -jar map.jar time.rel test.txt debug")

Runtime - Java Documentation

Install Composer

On Windows, you can use the Composer Windows Installer.

You could finish your Activity by calling Activity.finish(). However take care of the Android Activity life-cycle.

To set white colour of the image(arrow icon) on the button, we're using:

let imageOnButton = UIImage(named: "navForwardArrow")?.imageWithColor(color: UIColor.white)
button.setImage(imageOnButton, for: .normal)

Known issue: The icon looses its white colour while the button is pressed.

Screenshot:

I have catched the same exception and found a InnerException: SocketException. in the svclog trace.

After looking in the windows event log I saw an error coming from the System.ServiceModel.Activation.TcpWorkerProcess class.

Are you hosting your wcf service in IIS with netTcpBinding and port sharing?

It seems there is a bug in IIS port sharing feature, check the fix:

My solution is to host your WCF service in a Windows Service.

Select your terminal Command prompt instead of Power shell. That should work.

Bash can be pretty obtuse sometimes.

The following commands all return different error messages for basically the same error:

$ echo hello >
bash: syntax error near unexpected token `newline`

$ echo hello > ${NONEXISTENT}
bash: ${NONEXISTENT}: ambiguous redirect

$ echo hello > "${NONEXISTENT}"
bash: : No such file or directory

Adding quotes around the variable seems to be a good way to deal with the "ambiguous redirect" message: You tend to get a better message when you've made a typing mistake -- and when the error is due to spaces in the filename, using quotes is the fix.

I'd move to lists and solve it this way:

1. Sort both lists by id ascending using custom Comparator if objects in lists aren't Comparable
2. Iterate over elements in both lists like in merge phase in merge sort algorithm, but instead of merging lists, you check your logic.

The code would be more or less like this:

/* Main method */
private void execute(Collection<Foo> oldSet, Collection<Foo> newSet) {
  List<Foo> oldList = asSortedList(oldSet);
  List<Foo> newList = asSortedList(newSet);

  int oldIndex = 0;
  int newIndex = 0;
  // Iterate over both collections but not always in the same pace
  while( oldIndex < oldList.size() 
      && newIndex < newIndex.size())  {
    Foo oldObject = oldList.get(oldIndex);
    Foo newObject = newList.get(newIndex);

    // Your logic here
    if(oldObject.getId() < newObject.getId()) {
      doRemove(oldObject);
      oldIndex++;
    } else if( oldObject.getId() > newObject.getId() ) {
      doAdd(newObject);
      newIndex++;
    } else if( oldObject.getId() == newObject.getId() 
            && isModified(oldObject, newObject) ) {
      doUpdate(oldObject, newObject);
      oldIndex++;
      newIndex++;
    } else {
      ... 
    }
  }// while

  // Check if there are any objects left in *oldList* or *newList*

  for(; oldIndex < oldList.size(); oldIndex++ ) {
    doRemove( oldList.get(oldIndex) );  
  }// for( oldIndex )

  for(; newIndex < newList.size(); newIndex++ ) {
    doAdd( newList.get(newIndex) );
  }// for( newIndex ) 
}// execute( oldSet, newSet )

/** Create sorted list from collection 
    If you actually perform any actions on input collections than you should 
    always return new instance of list to keep algorithm simple.
*/
private List<Foo> asSortedList(Collection<Foo> data) {
  List<Foo> resultList;
  if(data instanceof List) {
     resultList = (List<Foo>)data;
  } else {
     resultList = new ArrayList<Foo>(data);
  }
  Collections.sort(resultList)
  return resultList;
}

It sounds like you're asking about a function

string Left(string s, int left)

that will return the leftmost left characters of the string s. In that case you can just use String.Substring. You can write this as an extension method:

public static class StringExtensions
{
    public static string Left(this string value, int maxLength)
    {
        if (string.IsNullOrEmpty(value)) return value;
        maxLength = Math.Abs(maxLength);

        return ( value.Length <= maxLength 
               ? value 
               : value.Substring(0, maxLength)
               );
    }
}

and use it like so:

string left = s.Left(number);

For your specific example:

string s = fac.GetCachedValue("Auto Print Clinical Warnings").ToLower() + " ";
string left = s.Substring(0, 1);

Another option is to use youtube-dl:

youtube-dl --skip-download --write-auto-sub $youtube_url

The default format is vtt and the other available format is ttml (--sub-format ttml).

--write-sub
       Write subtitle file

--write-auto-sub
       Write automatically generated subtitle file (YouTube only)

--all-subs
       Download all the available subtitles of the video

--list-subs
       List all available subtitles for the video

--sub-format FORMAT
       Subtitle format, accepts formats preference, for example: "srt" or "ass/srt/best"

--sub-lang LANGS
       Languages of the subtitles to download (optional) separated by commas, use --list-subs for available language tags

You can use ffmpeg to convert the subtitle file to another format:

ffmpeg -i input.vtt output.srt

This is what the VTT subtitles look like:

WEBVTT

You can see that each subtitle text is repeated three times. There is a new subtitle text every eighth line (3rd, 11th, 19th, and 27th).

This converts the VTT subtitles to a simpler format:

sed '1,/^$/d' *.vtt| # remove the part at the top
sed 's/<[^>]*>//g'| # remove tags
awk -F. 'NR%8==1{printf"%s ",$1}NR%8==3' # print each new subtitle text and its start time without milliseconds

This is what the output of the command above looks like:

00:00:01 ladies and gentlemen I'd like to thank
00:00:04 you for coming tonight especially at
00:00:05 such short notice
00:00:07 I'm sure mr. Irving will fill you in on
00:00:09 the circumstances that's brought us

This prints the closed captions of a video in the simplified format:

cap()(cd /tmp;rm -f -- *.vtt;youtube-dl --skip-download --write-auto-sub -- "$1";sed '1,/^$/d' -- *.vtt|sed 's/<[^>]*>//g'|awk -F. 'NR%8==1{printf"%s ",$1}NR%8==3')

The command below downloads the captions of all videos on a channel. When there is an error like Unable to extract video data, -i (--ignore-errors) causes youtube-dl to skip the video instead of exiting with an error.

youtube-dl -i --skip-download --write-auto-sub -o '%(upload_date)s.%(title)s.%(id)s.%(ext)s' https://www.youtube.com/channel/$channelid;for f in *.vtt;do sed '1,/^$/d' "$f"|sed 's/<[^>]*>//g'|awk -F. 'NR%8==1{printf"%s ",$1}NR%8==3'>"${f%.vtt}";done

Try this:

$array = array_values($array);

Using array_values()

Using Base64 string in JSON will be very heavy. The parser has to do a lot of heavy lifting. Currently, Fresco only supports base supports Base64. Better you put something on Amazon Cloud or Firebase Cloud. And get an image as a URL. So that you can use Picasso or Glide for caching.

     @Override
     public String toString() {
          return String.format("%15s /n %15d /n %15s /n %15s", name, age, Occupation, status);
     }

Here a JScript variant of JohnB's answer

// Below the MSDN page for MapNetworkDrive Method with link and in case if Microsoft breaks it like every now and then the path to the documentation of now.
// https://msdn.microsoft.com/en-us/library/8kst88h6(v=vs.84).aspx
// MSDN Library -> Web Development -> Scripting -> JScript and VBScript -> Windows Scripting -> Windows Script Host -> Reference (Windows Script Host) -> Methods (Windows Script Host) -> MapNetworkDrive Method

var WshNetwork = WScript.CreateObject('WScript.Network');
function localNameInUse(localName) {
    var driveIterator = WshNetwork.EnumNetworkDrives();
    for (var i=0, l=driveIterator.length; i < l; i += 2) {
        if (driveIterator.Item(i) == localName) {
            return true;

    }
    return false;
}

function mount(localName, remoteName) {
    if (localNameInUse(localName)) {
        WScript.Echo('"' + localName + '" drive letter already in use.');
    } else {
        WshNetwork.MapNetworkDrive(localName, remoteName);
    }
}

function unmount(localName) {
    if (localNameInUse(localName)) {
        WshNetwork.RemoveNetworkDrive(localName);

}

You can do it like this.

Models.TestModels obj = new Models.TestModels();
foreach (var item in obj.sp)
{
    Console.Write(item.Key);
    Console.Write(item.Value.name);
    Console.Write(item.Value.age);
}

The problem you most likely have right now is that the collection is private. If you add public to the beginning of this line

Dictionary<int, dynamic> sp = new Dictionary<int, dynamic> 

You should be able to access it from the function inside your controller.

Edit: Adding functional example of the full TestModels implementation.

Your TestModels class should look something like this.

public class TestModels
{
    public Dictionary<int, dynamic> sp = new Dictionary<int, dynamic>();

    public TestModels()
    {
        sp.Add(0, new {name="Test One", age=5});
        sp.Add(1, new {name="Test Two", age=7});
    }
}

You probably want to read up on the dynamic keyword as well.

You can solve this in two ways:

First way: If you wish to keep using REST you have to you a ModelAndView object to render a HTML page. An example is being posted by Happy Nguyen and I am posting it once more here:

@RequestMapping("/")
public ModelAndView index () {
    ModelAndView modelAndView = new ModelAndView();
    modelAndView.setViewName("index");
    return modelAndView;
}

Second Way: If it is not important weather you keep using REST or not, so you can just change the @RestController to @Controller and make sure that you have already added Thymeleaf template engine.

You can use the Calendar class to convert Date

public long getDifference()
{
    SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd kk:mm:ss z yyyy");
    Date d = sdf.parse("Mon May 27 11:46:15 IST 2013");

    Calendar c = Calendar.getInstance();
    c.setTime(d);
    long time = c.getTimeInMillis();
    long curr = System.currentTimeMillis();
    long diff = curr - time;    //Time difference in milliseconds
    return diff/1000;
}

In short,
The web server is a server that serves static web pages to users via HTTP requests.
The application server is a server that hosts the business logic for a system.
It often hosts both long-running/batch processes and/or interop services not meant for human consumption (REST/JSON services, SOAP, RPC, etc).

The following revision seeks to more clearly delineate PHP's array_filer(), array_map(), and array_walk(), all of which originate from functional programming:

array_filter() filters out data, producing as a result a new array holding only the desired items of the former array, as follows:

<?php
$array = array(1, "apples",2, "oranges",3, "plums");

$filtered = array_filter( $array, "ctype_alpha");
var_dump($filtered);
?>

live code here

All numeric values are filtered out of $array, leaving $filtered with only types of fruit.

array_map() also creates a new array but unlike array_filter() the resulting array contains every element of the input $filtered but with altered values, owing to applying a callback to each element, as follows:

<?php

$nu = array_map( "strtoupper", $filtered);
var_dump($nu);
?>

live code here

The code in this case applies a callback using the built-in strtoupper() but a user-defined function is another viable option, too. The callback applies to every item of $filtered and thereby engenders $nu whose elements contain uppercase values.

In the next snippet, array walk() traverses $nu and makes changes to each element vis a vis the reference operator '&'. The changes occur without creating an additional array. Every element's value changes in place into a more informative string specifying its key, category and value.

<?php

$f = function(&$item,$key,$prefix) {
    $item = "$key: $prefix: $item";
}; 
array_walk($nu, $f,"fruit");
var_dump($nu);    
?>    

See demo

Note: the callback function with respect to array_walk() takes two parameters which will automatically acquire an element's value and its key and in that order, too when invoked by array_walk(). (See more here).

There are some good answers here. I would add to them the following points.

What is the correct C# way of representing a data structure, which, "logically" (that is to say, "to the human mind") is just a list of things with a few bells and whistles?

Ask any ten non-computer-programmer people who are familiar with the existence of football to fill in the blank:

A football team is a particular kind of _____

Did anyone say "list of football players with a few bells and whistles", or did they all say "sports team" or "club" or "organization"? Your notion that a football team is a particular kind of list of players is in your human mind and your human mind alone.

List<T> is a mechanism. Football team is a business object -- that is, an object that represents some concept that is in the business domain of the program. Don't mix those! A football team is a kind of team; it has a roster, a roster is a list of players. A roster is not a particular kind of list of players. A roster is a list of players. So make a property called Roster that is a List<Player>. And make it ReadOnlyList<Player> while you're at it, unless you believe that everyone who knows about a football team gets to delete players from the roster.

Is inheriting from List<T> always unacceptable?

Unacceptable to who? Me? No.

When is it acceptable?

When you're building a mechanism that extends the List<T> mechanism.

What must a programmer consider, when deciding whether to inherit from List<T> or not?

Am I building a mechanism or a business object?

But that's a lot of code! What do I get for all that work?

You spent more time typing up your question that it would have taken you to write forwarding methods for the relevant members of List<T> fifty times over. You're clearly not afraid of verbosity, and we are talking about a very small amount of code here; this is a few minutes work.

UPDATE

I gave it some more thought and there is another reason to not model a football team as a list of players. In fact it might be a bad idea to model a football team as having a list of players too. The problem with a team as/having a list of players is that what you've got is a snapshot of the team at a moment in time. I don't know what your business case is for this class, but if I had a class that represented a football team I would want to ask it questions like "how many Seahawks players missed games due to injury between 2003 and 2013?" or "What Denver player who previously played for another team had the largest year-over-year increase in yards ran?" or "Did the Piggers go all the way this year?"

That is, a football team seems to me to be well modeled as a collection of historical facts such as when a player was recruited, injured, retired, etc. Obviously the current player roster is an important fact that should probably be front-and-center, but there may be other interesting things you want to do with this object that require a more historical perspective.

Your class has a base class, and this base class also has a property (which is not virtual or abstract) called Events which is being overridden by your class. If you intend to override it put the "new" keyword after the public modifier. E.G.

public new EventsDataTable Events
{
  ..
}

If you don't wish to override it change your properties' name to something else.

I was facing the same issue, to solve it I have added the below entry in pom.xml and performed a maven update.

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>

Using the spread operator:

const a = [1,2,3]
const [, ...rest] = a.reverse();
const withoutLast = rest.reverse();
console.log(withoutLast)

Tabview: lightweight python curses command line CSV file viewer (and also other tabular Python data, like a list of lists) is here on Github

Features:

• Python 2.7+, 3.x
• Unicode support
• Spreadsheet-like view for easily visualizing tabular data
• Vim-like navigation (h,j,k,l, g(top), G(bottom), 12G goto line 12, m - mark, ' - goto mark, etc.)
• Toggle persistent header row
• Dynamically resize column widths and gap
• Sort ascending or descending by any column. 'Natural' order sort for numeric values.
• Full-text search, n and p to cycle between search results
• 'Enter' to view the full cell contents
• Yank cell contents to clipboard
• F1 or ? for keybindings
• Can also use from python command line to visualize any tabular data (e.g. list-of-lists)

This might also help:

void ButtQuitClick(object sender, EventArgs e)
{
    QuitWin form = new QuitWin();
    form.Show();
}

Change ButtQuit to your button name and also change QuitWin to the name of the form that you made.

When the button is clicked it will open another window, you will need to make another form and a button on your main form for it to work.

Make (or rather a Makefile) is a buildsystem - it drives the compiler and other build tools to build your code.

CMake is a generator of buildsystems. It can produce Makefiles, it can produce Ninja build files, it can produce KDEvelop or Xcode projects, it can produce Visual Studio solutions. From the same starting point, the same CMakeLists.txt file. So if you have a platform-independent project, CMake is a way to make it buildsystem-independent as well.

If you have Windows developers used to Visual Studio and Unix developers who swear by GNU Make, CMake is (one of) the way(s) to go.

I would always recommend using CMake (or another buildsystem generator, but CMake is my personal preference) if you intend your project to be multi-platform or widely usable. CMake itself also provides some nice features like dependency detection, library interface management, or integration with CTest, CDash and CPack.

Using a buildsystem generator makes your project more future-proof. Even if you're GNU-Make-only now, what if you later decide to expand to other platforms (be it Windows or something embedded), or just want to use an IDE?

Borders on tables are always a bit flaky. One possibility would be to add a border-right declaration to each table cell except for the ones in right-most column. If you're using any kind of table-spacing this won't work very well.

Another option would be to use a 1px high background image with the borders inside it, but that'll only work if you can guarantee the width of each cell at all times.

Another possibility is to experiment with colgroup / col. This had fairly horrible support cross-browser the last time i looked at it but could have improved since then: http://www.webmasterworld.com/forum83/6826.htm

Just wrap the button label in an extra span and add class="align-middle" to both (the icon and the label). This will center your icon with text vertical.

<button id="edit-listing-form-house_Continue" 
    class="btn btn-large btn-primary"
    style=""
    value=""
    name="Continue"
    type="submit">
<span class="align-middle">Continue</span>
<i class="icon-ok align-middle" style="font-size:40px;"></i>

Just a side note, in Python 2.0 you could compare anything to anything (int to string). As this wasn't explicit, it was changed in 3.0, which is a good thing as you are not running into the trouble of comparing senseless values with each other or when you forget to convert a type.

Note that if the user may be in multiple zones used in the query, you may probably want to add .distinct(). Otherwise you get one user multiple times:

users_in_zones = User.objects.filter(zones__in=[zone1, zone2, zone3]).distinct()

The following will result in a comma separated list. Be sure to include a using statement for System.Linq

List<string> ls = new List<string>();
ls.Add("one");
ls.Add("two");
string type = ls.Aggregate((x,y) => x + "," + y);

will yield one,two

if you need a space after the comma, simply change the last line to string type = ls.Aggregate((x,y) => x + ", " + y);

function final_submit1() {
    var city = $("#city").val();
    var airport = $("#airport").val();

    var vehicle = $("#vehicle").val();

    if(city && airport){
    $.ajax({
        type:"POST",
        cache:false,
        data:{"city": city,"airport": airport},
        url:'http://airportLimo/ajax-car-list', 
        success: function (html) {
             console.log(html);
          //$('#add').val('data sent');
          //$('#msg').html(html);
           $('#pprice').html("Price: $"+html);
        }
      });

    }  
}

It looks like your Spring component scan Base is missing UserServiceImpl

<context:component-scan base-package="org.assessme.com.controller." />

I had the same problem. I followed the steps to change the icon but it always installed the default icon.

FIX: After I did the above, I rebuilt the solution by going to build on the Visual Studio menu bar and clicking on 'rebuild solution' and it worked!

Default html color code like this:

Red      #FF0000  rgb(255, 0, 0)
Maroon   #800000  rgb(128, 0, 0)
Yellow   #FFFF00  rgb(255, 255, 0)
Olive    #808000  rgb(128, 128, 0)
Blue     #0000FF  rgb(0, 0, 255)
Navy     #000080  rgb(0, 0, 128)
Fuchsia  #FF00FF  rgb(255, 0, 255)
Purple   #800080  rgb(128, 0, 128)

You probably want to look into the observer pattern.

Here's some sample code to get yourself started:

import java.util.*;

// An interface to be implemented by everyone interested in "Hello" events
interface HelloListener {
    void someoneSaidHello();
}

// Someone who says "Hello"
class Initiater {
    private List<HelloListener> listeners = new ArrayList<HelloListener>();

    public void addListener(HelloListener toAdd) {
        listeners.add(toAdd);
    }

    public void sayHello() {
        System.out.println("Hello!!");

        // Notify everybody that may be interested.
        for (HelloListener hl : listeners)
            hl.someoneSaidHello();
    }
}

// Someone interested in "Hello" events
class Responder implements HelloListener {
    @Override
    public void someoneSaidHello() {
        System.out.println("Hello there...");
    }
}

class Test {
    public static void main(String[] args) {
        Initiater initiater = new Initiater();
        Responder responder = new Responder();

        initiater.addListener(responder);

        initiater.sayHello();  // Prints "Hello!!!" and "Hello there..."
    }
}

This error might be caused by the jQuery event-aliases like .load(), .unload() or .error() that all are deprecated since jQuery 1.8. Lookup for these aliases in your code and replace them with the .on() method instead. For example, replace the following deprecated excerpt:

$(window).load(function(){...});

with the following:

$(window).on('load', function(){ ...});

I consider myself a complete newbie, but I think I have an extremely simple answer to one of the original subquestions that has not been stated here: accessing the data frames, or parts of it.

Let's start by creating the list with data frames as was stated above:

d1 <- data.frame(y1 = c(1, 2, 3), y2 = c(4, 5, 6))

d2 <- data.frame(y1 = c(3, 2, 1), y2 = c(6, 5, 4))

my.list <- list(d1, d2)

Then, if you want to access a specific value in one of the data frames, you can do so by using the double brackets sequentially. The first set gets you into the data frame, and the second set gets you to the specific coordinates:

my.list[[1]][[3,2]]

Check this UniversalVideoView library its simple and straight forward with controller as well.

Here is the code to play the video
Add this dependancyy in build.gradle

 implementation 'com.linsea:universalvideoview:1.1.0@aar'

Java Code

        UniversalVideoView mVideoView = findViewById(R.id.videoView);
        Uri uri=Uri.parse("https://firebasestorage.googleapis.com/v0/b/contactform-d9534.appspot.com/o/Vexento%20-%20Masked%20Heroes.mp4?alt=media&token=74c2e448-5b1b-47b7-b761-66409bcfbf56");
        mVideoView.setVideoURI(uri);
        UniversalMediaController mMediaController = findViewById(R.id.media_controller);
        mVideoView.setMediaController(mMediaController);
        mVideoView.start();   

Xml Code

            android:id="@+id/video_layout"
            android:layout_width="match_parent"
            android:layout_height="200dp"
            android:background="@android:color/black">

                android:layout_height="fill_parent"
                android:layout_gravity="center"
                app:uvv_autoRotation="true"
                app:uvv_fitXY="false" />

            <com.universalvideoview.UniversalMediaController

        </FrameLayout>

Just to throw this in, an often forgotten view is of security, picture this scenario if strings were mutable:

string dir = "C:\SomePlainFolder";

//Kick off another thread
GetDirectoryContents(dir);

void GetDirectoryContents(string directory)
{
  if(HasAccess(directory) {
    //Here the other thread changed the string to "C:\AllYourPasswords\"
    return Contents(directory);
  }
  return null;
}

You see how it could be very, very bad if you were allowed to mutate strings once they were passed.

HTML

<div id="myDiv" style="display:none;" class="answer_list" >WELCOME</div>
<input type="button" name="answer" onclick="ShowDiv()" />

JavaScript

function ShowDiv() {
    document.getElementById("myDiv").style.display = "";
}

Or if you wanted to use jQuery with a nice little animation:

<input id="myButton" type="button" name="answer" />

$('#myButton').click(function() {
  $('#myDiv').toggle('slow', function() {
    // Animation complete.
  });
});

Official FAQ ( https://reactjs.org/docs/hooks-faq.html#is-there-something-like-forceupdate ) now recommends this way if you really need to do it:

  const [ignored, forceUpdate] = useReducer(x => x + 1, 0);

  function handleClick() {
    forceUpdate();
  }

Now .find and .find_by_id methods are deprecated in rails 4. So instead we can use below:

Comment.where(id: [2, 3, 5])

It will work even if some of the ids don't exist. This works in the

user.comments.where(id: avoided_ids_array)

Also for excluding ID's

Comment.where.not(id: [2, 3, 5])

You should set the AllowRating property to true, preferably in the controller or model.
Like other inputs, the checkbox's state reflects the value of the property.

From tutorial here

"It has the extremely useful property that if all of the edges in a graph are unweighted (or the same weight) then the first time a node is visited is the shortest path to that node from the source node"

We can use map function

print map(str, EmployeeList)

Check Opacity, You can set this css property to the div, the <p> or using <span> you want to make transparent

And by the way, the font tag is deprecated, use css to style the text

div {
    opacity: 0.5;
} 

Edit: This code will make the whole element transparent, if you want to make ** just the text ** transparent check @Mattias Buelens answer

You can use default javascript cookies set method. this working perfect.

createCookieInHour: (cookieName, cookieValue, hourToExpire) => {

    date.setTime(date.getTime()+(hourToExpire*60*60*1000));
    document.cookie = cookieName + " = " + cookieValue + "; expires = " +date.toGMTString();
},

call java scripts funtion in react method as below,

createCookieInHour('cookieName', 'cookieValue', 5);

and you can use below way to view cookies.

let cookie = document.cookie.split(';');
console.log('cookie : ', cookie);

This works with font awesome:

<button class="btn btn-outline-success">
   <i class="fa fa-print" aria-hidden="true"></i>
   Print
</button>

The case-insensitive marker, (?i) can be incorporated directly into the regex pattern:

>>> import re
>>> s = 'This is one Test, another TEST, and another test.'
>>> re.findall('(?i)test', s)
['Test', 'TEST', 'test']

Here is an example to explain the most simple way of using getter and setter in java. One can do this in a more straightforward way but getter and setter have something special that is when using private member of parent class in child class in inheritance. You can make it possible through using getter and setter.

package stackoverflow;

    public class StackoverFlow 

    {

        private int x;

        public int getX()
        {
            return x;
        }

        public int setX(int x)
        {
          return  this.x = x;
        }
         public void showX()
         {
             System.out.println("value of x  "+x);
         }


        public static void main(String[] args) {

            StackoverFlow sto = new StackoverFlow();
            sto.setX(10);
            sto.getX();
            sto.showX();
        }

    }

Windows users just do a Windows Explorer search to find it.

The closest legal equivalent to illegal syntax mentioned in question is:

select * from myTable m
where not exists (
  select 1
  from table(sys.ku$_vcnt('Done', 'Finished except', 'In Progress')) patterns
  where m.status like patterns.column_value || '%'
)

Both mine and @Sethionic's answer make possible to list patterns dynamically (just by choosing other source than auxiliar sys.whatever table).

Note, if we had to search pattern inside string (rather than from the beginning) and database contained for example status = 'Done In Progress', then my solution (modified to like '%' || patterns.column_value || '%') would still generate one row for given record, whileas the @Sethionic's solution (modified to another auxiliar join before a) would produce multiple rows for each pattern occurence. Not judging which is better, just be aware of differences and choose which better fits your need.

var responseData = //Fetch Data

System.IO.File.WriteAllText(Server.MapPath("~/JsonData/jsondata.txt"), jsonData);

You don't necessarily have to choose between the two paradigms. You can write software with an OO architecture using many functional concepts. FP and OOP are orthogonal in nature.

Take for example C#. You could say it's mostly OOP, but there are many FP concepts and constructs. If you consider Linq, the most important constructs that permit Linq to exist are functional in nature: lambda expressions.

Another example, F#. You could say it's mostly FP, but there are many OOP concepts and constructs available. You can define classes, abstract classes, interfaces, deal with inheritance. You can even use mutability when it makes your code clearer or when it dramatically increases performance.

Many modern languages are multi-paradigm.

Recommended readings

As I'm in the same boat (OOP background, learning FP), I'd suggest you some readings I've really appreciated:

• Functional Programming for Everyday .NET Development, by Jeremy Miller. A great article (although poorly formatted) showing many techniques and practical, real-world examples of FP on C#.

• Real-World Functional Programming, by Tomas Petricek. A great book that deals mainly with FP concepts, trying to explain what they are, when they should be used. There are many examples in both F# and C#. Also, Petricek's blog is a great source of information.

Tip for 1 website resizing the height. But you can change to 2 websites.

Here is my code to resize an iframe with an external website. You need insert a code into the parent (with iframe code) page and in the external website as well, so, this won't work with you don't have access to edit the external website.

• local (iframe) page: just insert a code snippet
• remote (external) page: you need a "body onload" and a "div" that holds all contents. And body needs to be styled to "margin:0"

Local:

<IFRAME STYLE="width:100%;height:1px" SRC="http://www.remote-site.com/" FRAMEBORDER="no" BORDER="0" SCROLLING="no" ID="estframe"></IFRAME>

<SCRIPT>
var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
var eventer = window[eventMethod];
var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";
eventer(messageEvent,function(e) {
  if (e.data.substring(0,3)=='frm') document.getElementById('estframe').style.height = e.data.substring(3) + 'px';
},false);
</SCRIPT>

You need this "frm" prefix to avoid problems with other embeded codes like Twitter or Facebook plugins. If you have a plain page, you can remove the "if" and the "frm" prefix on both pages (script and onload).

Remote:

You need jQuery to accomplish about "real" page height. I cannot realize how to do with pure JavaScript since you'll have problem when resize the height down (higher to lower height) using body.scrollHeight or related. For some reason, it will return always the biggest height (pre-redimensioned).

<BODY onload="parent.postMessage('frm'+$('#master').height(),'*')" STYLE="margin:0">
<SCRIPT SRC="path-to-jquery/jquery.min.js"></SCRIPT>
<DIV ID="master">
your content
</DIV>

So, parent page (iframe) has a 1px default height. The script inserts a "wait for message/event" from the iframe. When a message (post message) is received and the first 3 chars are "frm" (to avoid the mentioned problem), will get the number from 4th position and set the iframe height (style), including 'px' unit.

The external site (loaded in the iframe) will "send a message" to the parent (opener) with the "frm" and the height of the main div (in this case id "master"). The "*" in postmessage means "any source".

Hope this helps. Sorry for my english.

(And if you have no admin access to the server)

ALTER ROLE <your_login_role> SET search_path TO a,b,c;

Two important things to know about:

1. When a schema name is not simple, it needs to be wrapped in double quotes.
2. The order in which you set default schemas a, b, c matters, as it is also the order in which the schemas will be looked up for tables. So if you have the same table name in more than one schema among the defaults, there will be no ambiguity, the server will always use the table from the first schema you specified for your search_path.

My computer crashed while I was writing a commit message. After rebooting, the working tree was as I had left it and I was able to successfully commit my changes.

However, when I tried to run git status I got

error: object file .git/objects/xx/12345 is empty
fatal: loose object xx12345 (stored in .git/objects/xx/12345 is corrupt

Unlike most of the other answers, I wasn't trying to recover any data. I just needed Git to stop complaining about the empty object file.

Overview

The "object file" is git's hashed representation of a real file that you care about. Git thinks it should have a hashed version of some/file.whatever stored in .git/object/xx/12345, and fixing the error turned out to be mostly a matter of figuring out which file the "loose object" was supposed to represent.

Details

Possible options seemed to be

1. Delete the empty file
2. Get the file into a state acceptable to Git

Approach 1: Remove the object file

The first thing I tried was just moving the object file

mv .git/objects/xx/12345 ..

That didn't work - git began complaining about a broken link. On to Approach 2.

Approach 2: Fix the file

Linus Torvalds has a great writeup of how to recover an object file that solved the problem for me. Key steps are summarized here.

$> # Find out which file the blob object refers to
$> git fsck
broken link from    tree 2d9263c6d23595e7cb2a21e5ebbb53655278dff8
           to    blob xx12345
missing blob xx12345

$> git ls-tree 2d926
...
10064 blob xx12345  your_file.whatever

This tells you what file the empty object is supposed to be a hash of. Now you can repair it.

$> git hash-object -w path/to/your_file.whatever

After doing this I checked .git/objects/xx/12345, it was no longer empty, and git stopped complaining.

That was simple for me!

Try to run the XAMPP Control Panel as administrator.

You can look at how Hector does this for Cassandra, where the goal is the same - convert everything to and from byte[] in order to store/retrieve from a NoSQL database - see here. For the primitive types (+String), there are special Serializers, otherwise there is the generic ObjectSerializer (expecting Serializable, and using ObjectOutputStream). You can, of course, use only it for everything, but there might be redundant meta-data in the serialized form.

I guess you can copy the entire package and make use of it.

The 2018 ES6 answer is:

return Object.is(x, undefined) ? y : x;

If variable x is undefined, return variable y... otherwise if variable x is defined, return variable x.

If using a SASS version (eg: thomas-mcdonald's one), then you may want to be slightly more dynamic (honor existing variables) and create all badge contexts using the same technique as used for labels:

// Colors
// Contextual variations of badges
// Bootstrap 3.0 removed contexts for badges, we re-introduce them, based on what is done for labels
.badge-default {
  @include label-variant($label-default-bg);
}

.badge-primary {
  @include label-variant($label-primary-bg);
}

.badge-success {
  @include label-variant($label-success-bg);
}

.badge-info {
  @include label-variant($label-info-bg);
}

.badge-warning {
  @include label-variant($label-warning-bg);
}

.badge-danger {
  @include label-variant($label-danger-bg);
}

The LESS equivalent should be straightforward.

I changed a few things to work with Option Explicit, and the code ran fine against a cell containing "abc.123", which returned "abc.12,". There were no compile errors.

Option Explicit ' This is new

Public Function ProcessString(input_string As String) As String
    ' The temp string used throughout the function
    Dim temp_string As String
    Dim i As Integer ' This is new
    Dim return_string As String ' This is new
    For i = 1 To Len(input_string)
        temp_string = Mid(input_string, i, 1)
        If temp_string Like "[A-Z, a-z, 0-9, :, -]" Then
            return_string = return_string & temp_string
        End If
    Next i
    return_string = Mid(return_string, 1, (Len(return_string) - 1))
    ProcessString = return_string & ", "
End Function

I'll suggest you post more of your relevant code (that calls this function). You've stated that last_name is a String, but it appears that may not be the case. Step through your code line by line and ensure that this is actually the case.

It's 2021... keep it simple.

Times have changed and now the cleanest and most readable way to do this is:

Array.from(document.querySelectorAll('widget hover')).forEach((el) => el.classList.remove('hover'));

If you can't support arrow functions then just convert it like this:

Array.from(document.querySelectorAll('widget hover')).forEach(function(el) { 
    el.classList.remove('hover');
});

Additionally if you need to support extremely old browsers then use a polyfil for the forEach and Array.from and move on with your life.

okey I believe the fastest way it would be

import os
print(os.popen('command').readline())
x = _
print(x)

As others pointed out, the most straightforward way to deploy a WAR is to copy it to the webapps of the Tomcat install. Another option would be to use the manager application if it is installed (this is not always the case), if it's properly configured (i.e. if you have the credentials of a user assigned to the appropriate group) and if it you can access it over an insecure network like Internet (but this is very unlikely and you didn't mention any VPN access). So this leaves you with the webappdirectory.

Now, if Tomcat is installed and running on bilgin.ath.cx (as this is the machine where you uploaded the files), I noticed that Apache is listening to port 80 on that machien so I would bet that Tomcat is not directly exposed and that requests have to go through Apache. In that case, I think that deploying a new webapp and making it visible to the Internet will involve the edit of Apache configuration files (mod_jk?, mod_proxy?). You should either give us more details or discuss this with your hosting provider.

Update: As expected, the bilgin.ath.cx is using Apache Tomcat + Apache HTTPD + mod_jk. The configuration usually involves two files: the worker.properties file to configure the workers and the httpd.conf for Apache. Now, without seeing the current configuration, it's not easy to give a definitive answer but, basically, you may have to add a JkMount directive in Apache httpd.conf for your new webapp¹. Refer to the mod_jk documentation, it has a simple configuration example. Note that modifying httpd.conf will require access to (obviously) and proper rights and that you'll have to restart Apache after the modifications.

_{¹ I don't think you'll need to define a new worker if you are deploying to an already used Tomcat instance, especially if this sounds like Chinese for you :)}

you just need to divide the Date Time stamp by 1000 like:

var a = 1437203995000;
a = (a)/1000;

It completely depends on the contexts in which the data structure is needed. For example, if you are creating items to be used by other functions or services using List is the perfect way to accomplish it.

Now if you have a list of items and you just want to display them, say on a web page array is the container you need to use.

Hibernate uses a ConnectionProvider internally to obtain connections. From the hibernate javadoc:

The ConnectionProvider interface is not intended to be exposed to the application. Instead it is used internally by Hibernate to obtain connections.

The more elegant way of solving this would be to create a database connection pool yourself and hand connections to hibernate and your legacy tool from there.

First you have to install the Illuminate Html helper class:

composer require "illuminate/html":"5.0.*"

Next you need to open /config/app.php and update as follows:

'providers' => [

...

Illuminate\Html\HtmlServiceProvider::class,
],

'aliases' => [

...

'Form' => Illuminate\Html\FormFacade::class, 
'HTML' => Illuminate\Html\HtmlFacade::class,
],

To confirm it’s working use the following command:

php artisan tinker
> Form::text('foo')
"<input name=\"foo\" type=\"text\">"

To include external css in you files, use the following syntax:

{!! HTML::style('foo/bar.css') !!}

Years later, another one is below. But for everyday use I just

np.set_printoptions( threshold=20, edgeitems=10, linewidth=140,
    formatter = dict( float = lambda x: "%.3g" % x ))  # float arrays %.3g

''' printf( "... %.3g ... %.1f  ...", arg, arg ... ) for numpy arrays too

Example:
    printf( """ x: %.3g   A: %.1f   s: %s   B: %s """,
                   x,        A,        "str",  B )

If `x` and `A` are numbers, this is like `"format" % (x, A, "str", B)` in python.
If they're numpy arrays, each element is printed in its own format:
    `x`: e.g. [ 1.23 1.23e-6 ... ]  3 digits
    `A`: [ [ 1 digit after the decimal point ... ] ... ]
with the current `np.set_printoptions()`. For example, with
    np.set_printoptions( threshold=100, edgeitems=3, suppress=True )
only the edges of big `x` and `A` are printed.
`B` is printed as `str(B)`, for any `B` -- a number, a list, a numpy object ...

`printf()` tries to handle too few or too many arguments sensibly,
but this is iffy and subject to change.

How it works:
numpy has a function `np.array2string( A, "%.3g" )` (simplifying a bit).
`printf()` splits the format string, and for format / arg pairs
    format: % d e f g
    arg: try `np.asanyarray()`
-->  %s  np.array2string( arg, format )
Other formats and non-ndarray args are left alone, formatted as usual.

Notes:

`printf( ... end= file= )` are passed on to the python `print()` function.

Only formats `% [optional width . precision] d e f g` are implemented,
not `%(varname)format` .

%d truncates floats, e.g. 0.9 and -0.9 to 0; %.0f rounds, 0.9 to 1 .
%g is the same as %.6g, 6 digits.
%% is a single "%" character.

The function `sprintf()` returns a long string. For example,
    title = sprintf( "%s  m %g  n %g  X %.3g",
                    __file__, m, n, X )
    print( title )
    ...
    pl.title( title )

Module globals:
_fmt = "%.3g"  # default for extra args
_squeeze = np.squeeze  # (n,1) (1,n) -> (n,) print in 1 line not n

Fix:

I chose the "ISAPI & CGI Restrictions" after clicking the server name (not the site name) in IIS Manager, and right clicked the "ASP.NET v4.0.30319" lines and chose "Allow".

After turning on ASP.NET from "Programs and Features > Turn Windows features on or off", you must install ASP.NET from the Windows command prompt. The MIME types don't ever show up, but after doing this command, I noticed these extensions showed up under the IIS web site "Handler Mappings" section of IIS Manager.

From the official JAR File Specification (link goes to the Java 7 version, but the text hasn't changed since at least v1.3):

The META-INF directory

The following files/directories in the META-INF directory are recognized and interpreted by the Java 2 Platform to configure applications, extensions, class loaders and services:

• MANIFEST.MF

The manifest file that is used to define extension and package related data.

• INDEX.LIST

This file is generated by the new "-i" option of the jar tool, which contains location information for packages defined in an application or extension. It is part of the JarIndex implementation and used by class loaders to speed up their class loading process.

• x.SF

The signature file for the JAR file. 'x' stands for the base file name.

• x.DSA

The signature block file associated with the signature file with the same base file name. This file stores the digital signature of the corresponding signature file.

• services/

This directory stores all the service provider configuration files.

This error can come not only because of the Date conversions

This error can come when we try to pass date whereas varchar is expected
or
when we try to pass varchar whereas date is expected.

Use to_char(sysdate,'YYYY-MM-DD') when varchar is expected

You can do Your own Animation style as an xml file like this(put it in anim folder):

left to right:

  <set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
        <translate android:fromXDelta="-100%" android:toXDelta="0%"
         android:fromYDelta="0%" android:toYDelta="0%"
         android:duration="500"/>
  </set>

right to left:

    <set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
     <translate
        android:fromXDelta="0%" android:toXDelta="100%"
        android:fromYDelta="0%" android:toYDelta="0%"
        android:duration="500" />
   </set>

here You can set Your own values at duration, maybe it depends on the phone model how the animation will look like, try some values out if it looks not good.

and then You can call it in Your activity:

     Intent animActivity = new Intent(this,YourStartAfterAnimActivity.class);
      startActivity(nextActivity);

      overridePendingTransition(R.anim.your_left_to_right, R.anim.your_right_to_left);

The format option %ai was what I wanted:

%ai: author date, ISO 8601-like format

--format="%ai"

Note that as of Microsoft SQL Server 2016, UTF-8 is supported by bcp, BULK_INSERT, and OPENROWSET.

Addendum 2016-12-21: SQL Server 2016 SP1 now enables Unicode Compression (and most other previously Enterprise-only features) for all versions of MS SQL including Standard and Express. This is not the same as UTF-8 support, but it yields a similar benefit if the goal is disk space reduction for Western alphabets.

Extending Alex's answer slightly:

class User:
    def __init__(self):
        self.data = [1,2,3]
        self.other_data = [4,5,6]
    def doSomething(self, source):
        dataSource = getattr(self,source)
        return dataSource

A = User()
print A.doSomething("data")
print A.doSomething("other_data")

will yield:

[1, 2, 3]
[4, 5, 6]

However, personally I don't think that's great style - getattr will let you access any attribute of the instance, including things like the doSomething method itself, or even the __dict__ of the instance. I would suggest that instead you implement a dictionary of data sources, like so:

class User:
    def __init__(self):

        self.data_sources = {
            "data": [1,2,3],
            "other_data":[4,5,6],
        }

    def doSomething(self, source):
        dataSource = self.data_sources[source]
        return dataSource

A = User()

print A.doSomething("data")
print A.doSomething("other_data")

again yielding:

[1, 2, 3]
[4, 5, 6]

Changing history

If it is the most recent commit, you can simply do this:

git commit --amend

This brings up the editor with the last commit message and lets you edit the message. (You can use -m if you want to wipe out the old message and use a new one.)

Pushing

And then when you push, do this:

git push --force-with-lease <repository> <branch>

Or you can use "+":

git push <repository> +<branch>

Or you can use --force:

git push --force <repository> <branch>

Be careful when using these commands.

• If someone else pushed changes to the same branch, you probably want to avoid destroying those changes. The --force-with-lease option is the safest, because it will abort if there are any upstream changes (

• If you don't specify the branch explicitly, Git will use the default push settings. If your default push setting is "matching", then you may destroy changes on several branches at the same time.

Pulling / fetching afterwards

Anyone who already pulled will now get an error message, and they will need to update (assuming they aren't making any changes themselves) by doing something like this:

git fetch origin
git reset --hard origin/master # Loses local commits

Be careful when using reset --hard. If you have changes to the branch, those changes will be destroyed.

A note about modifying history

The destroyed data is really just the old commit message, but --force doesn't know that, and will happily delete other data too. So think of --force as "I want to destroy data, and I know for sure what data is being destroyed." But when the destroyed data is committed, you can often recover old commits from the reflog—the data is actually orphaned instead of destroyed (although orphaned commits are periodically deleted).

If you don't think you're destroying data, then stay away from --force... bad things might happen.

This is why --force-with-lease is somewhat safer.

Only a teacher would ask you to do something silly like this. You could provide an expected answer. Or a unique solution, while the rest of the class will be (yawn) the same...

from operator import lt, gt
def ultimate (l,op,c=1,u=0):
    try:
        if op(l[c],l[u]): 
            u = c
        c += 1
        return ultimate(l,op,c,u)
    except IndexError:
        return l[u]
def minimum (l):
    return ultimate(l,lt)
def maximum (l):
    return ultimate(l,gt)

The solution is simple. Use this to set yourself apart from obvious choices.

If buttonSearch has no code, and only action is to return dialog result then:

    private void textBox1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
            DialogResult = DialogResult.OK;
    }

You could use the library lxml (Note top level link is now spam) , which is a superset of ElementTree. Its tostring() method includes a parameter pretty_print - for example:

>>> print(etree.tostring(root, pretty_print=True))
<root>
  <child1/>
  <child2/>
  <child3/>
</root>

Yes, as other answers have states, it cannot be done with Write-Output. Where PowerShell fails, turn to .NET, there are even a couple of .NET answers here but they are more complex than they need to be.

Just use:

[Console]::Write("Enabling feature XYZ.......")
Enable-SPFeature...
Write-Output "Done"

It is not purest PowerShell, but it works.

Select Tasks, Export Data

Select Source DB

Select Destination: Flat File Destination

Pick a file name

Select Format - Delimited

Choose a table or write a query

Pick a Column delimiter

Note: You can pick a Text qualifier that will delimit your text fields, such as quotes.

If you have a field with commas, don't use you use comma as a delimiter, because it does not escape commas. You can pick a column delimiter such as Vertical Bar: | instead of comma, or a tab character. Otherwise, write a query that escapes your commas or delimits your varchar field.

The escape character or text qualifier you need to use depends on your requirements.

Just to offer you a different angle -

I find it's not a good idea to maintain public variables between function calls. Any variables you need to use should be stored in Subs and Functions and passed as parameters. Once the code is done running, you shouldn't expect the VBA Project to maintain the values of any variables.

The reason for this is that there is just a huge slew of things that can inadvertently reset the VBA Project while using the workbook. When this happens, any public variables get reset to 0.

If you need a value to be stored outside of your subs and functions, I highly recommend using a hidden worksheet with named ranges for any information that needs to persist.

The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date') declare the date property like so: private _date: string;. Also, make sure you are instantiating the model with the new keyword. Lastly, access the property using regular dot notation.

Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :

let passcode = "secret passcode";

class Employee {
    private _fullName: string;

    get fullName(): string {
        return this._fullName;
    }

    set fullName(newName: string) {
        if (passcode && passcode == "secret passcode") {
            this._fullName = newName;
        }
        else {
            console.log("Error: Unauthorized update of employee!");
        }
    }
}

let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
    console.log(employee.fullName);
}

And here is a plunker demonstrating what it sounds like you're trying to do: https://plnkr.co/edit/OUoD5J1lfO6bIeME9N0F?p=preview

A character set is a subset of all written glyphs. A character encoding specifies how those characters are mapped to numeric values. Some character encodings, like UTF-8 and UTF-16, can encode any character in the Universal Character Set. Others, like US-ASCII or ISO-8859-1 can only encode a small subset, since they use 7 and 8 bits per character, respectively. Because many standards specify both a character set and a character encoding, the term "character set" is often substituted freely for "character encoding".

A collation comprises rules that specify how characters can be compared for sorting. Collations rules can be locale-specific: the proper order of two characters varies from language to language.

Choosing a character set and collation comes down to whether your application is internationalized or not. If not, what locale are you targeting?

In order to choose what character set you want to support, you have to consider your application. If you are storing user-supplied input, it might be hard to foresee all the locales in which your software will eventually be used. To support them all, it might be best to support the UCS (Unicode) from the start. However, there is a cost to this; many western European characters will now require two bytes of storage per character instead of one.

Choosing the right collation can help performance if your database uses the collation to create an index, and later uses that index to provide sorted results. However, since collation rules are often locale-specific, that index will be worthless if you need to sort results according to the rules of another locale.

In my case, I wanted to check out a new branch that has cut recently but it's it big in size and I want to save time and internet bandwidth, as I'm in a slow metered network

so I copped the previous branch that I already checked in

I went to the working directory, and from svn info, I can see it's on the previous branch I did the following command (you can find this command from svn switch --help)

svn switch ^/branches/newBranchName

go check svn info again you can see it is becoming the newBranchName go ahead and svn up

and this how I got the new branch easily, quickly with minimum data transmitting over the internet

hope sharing my case helps and speeds up your work

Building on the Python 2 solution from @GarethLatty, the following is a way to get a single line equivalent without intermediate variables in Python 2.

t=iter([1, 1, 2, 3, 5, 8, 13, 21, 34, 55]);h,t = [(h,list(t)) for h in t][0]

If you need it to be exception-proof (i.e. supporting empty list), then add:

t=iter([]);h,t = ([(h,list(t)) for h in t]+[(None,[])])[0]

If you want to do it without the semicolon, use:

h,t = ([(h,list(t)) for t in [iter([1,2,3,4])] for h in t]+[(None,[])])[0]

sudo apt-get install nodejs does not work for me. In order to get it to work, I have to do the following:

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs

Hope this will help someone having the same problem as me.

You can use the following to programmatically center TextView text in Kotlin:

textview.gravity = Gravity.CENTER

Before going into Bucketing, we need to understand what Partitioning is. Let us take the below table as an example. Note that I have given only 12 records in the below example for beginner level understanding. In real-time scenarios you might have millions of records.

PARTITIONING
---------------------
Partitioning is used to obtain performance while querying the data. For example, in the above table, if we write the below sql, it need to scan all the records in the table which reduces the performance and increases the overhead.

select * from sales_table where product_id='P1'

To avoid full table scan and to read only the records related to product_id='P1' we can partition (split hive table's files) into multiple files based on the product_id column. By this the hive table's file will be split into two files one with product_id='P1' and other with product_id='P2'. Now when we execute the above query, it will scan only the product_id='P1' file.

../hive/warehouse/sales_table/product_id=P1
../hive/warehouse/sales_table/product_id=P2

The syntax for creating the partition is given below. Note that we should not use the product_id column definition along with the non-partitioned columns in the below syntax. This should be only in the partitioned by clause.

create table sales_table(sales_id int,trans_date date, amount int) 
partitioned by (product_id varchar(10))

Cons : We should be very careful while partitioning. That is, it should not be used for the columns where number of repeating values are very less (especially primary key columns) as it increases the number of partitioned files and increases the overhead for the Name node.

BUCKETING
------------------
Bucketing is used to overcome the cons that I mentioned in the partitioning section. This should be used when there are very few repeating values in a column (example - primary key column). This is similar to the concept of index on primary key column in the RDBMS. In our table, we can take Sales_Id column for bucketing. It will be useful when we need to query the sales_id column.

Below is the syntax for bucketing.

create table sales_table(sales_id int,trans_date date, amount int) 
partitioned by (product_id varchar(10)) Clustered by(Sales_Id) into 3 buckets

Here we will further split the data into few more files on top of partitions.

Since we have specified 3 buckets, it is split into 3 files each for each product_id. It internally uses modulo operator to determine in which bucket each sales_id should be stored. For example, for the product_id='P1', the sales_id=1 will be stored in 000001_0 file (ie, 1%3=1), sales_id=2 will be stored in 000002_0 file (ie, 2%3=2),sales_id=3 will be stored in 000000_0 file (ie, 3%3=0) etc.

The syntax to store the command output into a variable is var=$(command).

So you can directly do:

result=$(ls -l | grep -c "rahul.*patle")

And the variable $result will contain the number of matches.

We had a similar issue and we managed to fix it by setting the Platform target to x86.

 window.open($('#myanchor').attr('href'));

               $('#myanchor')[0].click();

Example of a Boolean (AND) plus Wildcard search, which I'm using inside a javascript Autocomplete plugin:

String to match: "my word"

String to search: "I'm searching for my funny words inside this text"

You need the following regex: /^(?=.*my)(?=.*word).*$/im

Explaining:

^ assert position at start of a line

?= Positive Lookahead

.* matches any character (except newline)

() Groups

$ assert position at end of a line

i modifier: insensitive. Case insensitive match (ignores case of [a-zA-Z])

m modifier: multi-line. Causes ^ and $ to match the begin/end of each line (not only begin/end of string)

Test the Regex here: https://regex101.com/r/iS5jJ3/1

So, you can create a javascript function that:

1. Replace regex reserved characters to avoid errors
2. Split your string at spaces
3. Encapsulate your words inside regex groups
4. Create a regex pattern
5. Execute the regex match

Example:

function fullTextCompare(myWords, toMatch){_x000D_
    //Replace regex reserved characters_x000D_
    myWords=myWords.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');_x000D_
    //Split your string at spaces_x000D_
    arrWords = myWords.split(" ");_x000D_
    //Encapsulate your words inside regex groups_x000D_
    arrWords = arrWords.map(function( n ) {_x000D_
        return ["(?=.*"+n+")"];_x000D_
    });_x000D_
    //Create a regex pattern_x000D_
    sRegex = new RegExp("^"+arrWords.join("")+".*$","im");_x000D_
    //Execute the regex match_x000D_
    return(toMatch.match(sRegex)===null?false:true);_x000D_
}_x000D_
_x000D_
//Using it:_x000D_
console.log(_x000D_
    fullTextCompare("my word","I'm searching for my funny words inside this text")_x000D_
);_x000D_
_x000D_
//Wildcards:_x000D_
console.log(_x000D_
    fullTextCompare("y wo","I'm searching for my funny words inside this text")_x000D_
);

1. In your project folder, create a “.gdbinit” text file. It will contain your gdb debugger configuration
2. Edit “.gdbinit”, and add the line (without the quotes) : “set new-console on”

3. After building the project right click on the project Debug > “Debug Configurations”, as shown below

4. In the “debugger” tab, ensure the “GDB command file” now points to your “.gdbinit” file. Else, input the path to your “.gdbinit” configuration file :

5. Click “Apply” and “Debug”. A native DOS command line should be launched as shown below

Try something like this:

foreach (ListItem listItem in clbIncludes.Items)
{
    if (listItem.Selected) { 
        //do some work 
    }
    else { 
        //do something else 
    }
}

NumPy has a numpy.mean which is an arithmetic mean. Usage is as simple as this:

>>> import numpy
>>> a = [1, 2, 4]
>>> numpy.mean(a)
2.3333333333333335

Since Java 11 the most convenient way it to use java.net.http.HttpClient from the standard library.

Example:

HttpRequest request = HttpRequest.newBuilder(new URI(
    "https://stackoverflow.com/questions/6159118/using-java-to-pull-data-from-a-webpage"))
  .timeout(Duration.of(10, SECONDS))
  .GET()
  .build();

HttpResponse<String> response = HttpClient.newHttpClient()
  .send(request, BodyHandlers.ofString());

if (response.statusCode() != 200) {
  throw new RuntimeException(
    "Invalid response: " + response.statusCode() + ", request: " + response);
}

System.out.println(response.body());

Here's the most common use case. Suppose you're switching on an enum value:

switch (fruit) {
  case apple:
    // do something
    break;
  case pear:
    // do something
    break;
  case banana:
    // do something
    break;
}

As long as you handle every case, you're fine. But someday, somebody will add fig to your enum and forget to add it to your switch statement. This produces a bug that may get tricky to catch, because the effects won't be felt until after you've left the switch statement. But if you write your switch like this, you can catch it immediately:

switch (fruit) {
  case apple:
    // do something
    break;
  case pear:
    // do something
    break;
  case banana:
    // do something
    break;
  default:
    assert false : "Missing enum value: " + fruit;
}

I have recently written a blog about it for the Laravel5.6. Link to blog is https://www.samundra.com.np/integrating-font-awesome-with-laravel-5.x-using-webpack/1574

The steps are similar to above description. But in my case, I had to do extra steps like configuring the webfonts path to font-awesome in "public" directory. Setting the resource root in Laravel mix etc. You can find the details in the blog.

I am leaving the link here so it helps people for whom the mentioned solutions don't work.

I think the simplest way would be

 return new Friend[0];

The requirements of the return are merely that the method return an object which implements IEnumerable<Friend>. The fact that under different circumstances you return two different kinds of objects is irrelevant, as long as both implement IEnumerable.

Try this code for Kotlin

 val display = windowManager.defaultDisplay
 val size = Point()
 display.getSize(size)
 var DEVICE_WIDTH = size.x
 var DEVICE_HEIGHT = size.y

instanceof is just syntactic sugar for isPrototypeOf:

function Ctor() {}
var o = new Ctor();

o instanceof Ctor; // true
Ctor.prototype.isPrototypeOf(o); // true

o instanceof Ctor === Ctor.prototype.isPrototypeOf(o); // equivalent

instanceof just depends on the prototype of a constructor of an object.

A constructor is just a normal function. Strictly speaking it is a function object, since everything is an object in Javascript. And this function object has a prototype, because every function has a prototype.

A prototype is just a normal object, which is located within the prototype chain of another object. That means being in the prototype chain of another object makes an object to a prototype:

function f() {} //  ordinary function
var o = {}, // ordinary object
 p;

f.prototype = o; // oops, o is a prototype now
p = new f(); // oops, f is a constructor now

o.isPrototypeOf(p); // true
p instanceof f; // true

The instanceof operator should be avoided because it fakes classes, which do not exist in Javascript. Despite the class keyword not in ES2015 either, since class is again just syntactic sugar for...but that's another story.

Another alternative is the old school NET USER commands:

NET USER username "password" /ADD

OK - you can't set all the options but it's a lot less convoluted for simple user creation & easy to script up in Powershell.

NET LOCALGROUP "group" "user" /add to set group membership.

You can use Janitor package remove_empty

library(janitor)

df %>%
  remove_empty(c("rows", "cols")) #select either row or cols or both

Also, Another dplyr approach

 library(dplyr) 
 df %>% select_if(~all(!is.na(.)))

OR

df %>% select_if(colSums(!is.na(.)) == nrow(df))

this is also useful if you want to only exclude / keep column with certain number of missing values e.g.

 df %>% select_if(colSums(!is.na(.))>500)

The solution for me was to install the oracle unlimited JCE and install in JRE_HOME/lib/security. Then restarted glassfish and I was able to connect to my sftp server using jsch.

If you're using Spring you can simply call HtmlUtils.htmlEscape(String input) which will handle the '&' to '&' translation.

The permament pool contains everything that is not your application data, but rather things required for the VM: typically it contains interned strings, the byte code of defined classes, but also other "not yours" pieces of data.

Take a look at this JQuery plugin:

http://fixedheadertable.com

It adds vertical (fixed header row) or horizontal (fixed first column) scrolling to an existing HTML table. There is a demo you can check for both cases of scrolling.

If you are using Bash, then use:

command >/dev/null |& grep "something"

http://www.gnu.org/software/bash/manual/bashref.html#Pipelines

You could use:

sorted(d.items(), key=lambda x: x[1])

This will sort the dictionary by the values of each entry within the dictionary from smallest to largest.

To sort it in descending order just add reverse=True:

sorted(d.items(), key=lambda x: x[1], reverse=True)

Input:

d = {'one':1,'three':3,'five':5,'two':2,'four':4}
a = sorted(d.items(), key=lambda x: x[1])    
print(a)

Output:

[('one', 1), ('two', 2), ('three', 3), ('four', 4), ('five', 5)]

You can also use html to override the css locally. I was having a similar issue and this worked for me:

<html>
<body>

<h4>A nested List:</h4>
<ul style="PADDING-LEFT: 12px">
  <li>Coffee</li>
  <li>Tea
    <ul>
    <li>Black tea</li>
    <li>Green tea</li>
    </ul>
  </li>
  <li>Milk</li>
</ul>

</body>
</html>

yeah you will come across of various issues using HTML5 datepicker, it would work with some or might not be. I faced the same issue. Please check this DatePicker Demo, I solved my problem with this plugin. Its very good and flexible datepicker plugin with complete demo. It is completely compatible with mobile browsers too and can be integrated with jquery mobile too.

I just copy the file name Queue.py in the */lib/python2.7/ to queue.py and that solved my problem.

List is just an interface. The question is: is your actual List implementation serializable? Speaking about the standard List implementations (ArrayList, LinkedList) from the Java run-time, most of them actually are already.

It seems to be a python bug (that works perfectly in vim). The source of the problem is the (\s*...)+ bit. Basically , you can't do (\s*)+ which make sense , because you are trying to repeat something which can be null.

>>> re.compile(r"(\s*)+")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/re.py", line 180, in compile
    return _compile(pattern, flags)
  File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/re.py", line 233, in _compile
    raise error, v # invalid expression
sre_constants.error: nothing to repeat

However (\s*\1) should not be null, but we know it only because we know what's in \1. Apparently python doesn't ... that's weird.

I use proxychains ssh user@host; from proxychains-ng (see https://github.com/rofl0r/proxychains-ng).
By default it uses a socks4 proxy at 127.0.0.1:9050 but it can be changed in the conf file /etc/proxychains.conf or you can specify another conf file proxychains -f custom.conf

Add These two lines in your text

android:ellipsize="end"
android:singleLine="true"

background-image takes an url as a value. Use either

background-image: url ('/image/btn.png');

or

background: url ('/image/btn.png') no-repeat;

which is a shorthand for

background-image: url ('/image/btn.png');
background-repeat: no-repeat;

Also, you might want to look at the button HTML element for fancy submit buttons.

Easiest way i found -

1. Uninstall current version
2. Download the appropriate .msi installer (x64 or x86) for the desired version from https://nodejs.org/download/release/

1. Static means..You can use it without instantiate of the class or using any object.

2. final..It is a keyword which is used for make the string constant. You can not change the value of that string. Look at the example below:

     public class StringTest { 
              static final String str = "Hello"; 
     public static void main(String args[]) { 
              // str = "world"; // gives error 
              System.out.println(str); // called without the help of an object                       
              System.out.println(StringTest.str);// called with class name  
                } 
            } 
   

Thanks

1. You need

   @ManagedBean(name="userBean")

2. Make sure you have getUser() method.

3. Type of setUser() method should be void.

4. Make sure that User class has proper setters and getters as well.

An ECMAScript 6 solution with reflection. Create a wrapper like:

my problem was with the accents (á É ñ ) and the plus sign (+) when i to try to save javascript "code examples" to mysql:

my solution (not the better way, but it works):

javascript:

function replaceAll( text, busca, reemplaza ){
  while (text.toString().indexOf(busca) != -1)
  text = text.toString().replace(busca,reemplaza);return text;
}


function cleanCode(cod){
code = replaceAll(cod , "|", "{1}" ); // error | palos de explode en java
code = replaceAll(code, "+", "{0}" ); // error con los signos mas   
return code;
}

function to save:

function save(pid,code){
code = cleanCode(code); // fix sign + and |
code = escape(code); // fix accents
var url = 'editor.php';
var variables = 'op=save';
var myData = variables +'&code='+ code +'&pid='+ pid +'&newdate=' +(new Date()).getTime();    
var result = null;
$.ajax({
datatype : "html",
data: myData,  
url: url,
success : function(result) {
    alert(result); // result ok                     
},
}); 
} // end function

function in php:

<?php
function save($pid,$code){
    $code= preg_replace("[\{1\}]","|",$code);
    $code= preg_replace("[\{0\}]","+",$code);
    mysql_query("update table set code= '" . mysql_real_escape_string($code) . "' where pid='$pid'");
}

You can find if the textbox is disabled using is method by passing :disabled selector to it. Try this.

if($('textbox').is(':disabled')){
     //textbox is disabled
}

You can also use head and tail:

In [29]: pd.concat([df.head(1), df.tail(1)])
Out[29]:
   a  b
0  1  a
3  4  d

it is basically multiplying and dividing with the base power 2

shift left = x * 2 ^ y

shift right = x / 2 ^ y

shl eax,2 = 2 * 2 ^ 2 = 8

shr eax,3 = 2 / 2 ^ 3 = 1/4

change user to root

sodu su -

browse to etc

vi sudoers

look for root user in user priviledge section. you will get it like

root ALL=(ALL:ALL) ALL 

make same entry for your user name. if you username is 'myuser' then add

myuser ALL=(ALL:ALL) ALL

it will look like

root ALL=(ALL:ALL) ALL 

myuser ALL=(ALL:ALL) ALL 

save it. change root user to your user. now try the same where you were getting the sudoers issue

You have forgotten a * between -3.7 and (prof[x]).

Thus:

for x in range(len(prof)):
    PB = 2.25 * (1 - math.pow(math.e, (-3.7 * (prof[x])/2.25))) * (math.e, (0/2.25)))

Also, there seems to be missing an ( as I count 6 times ( and 7 times ), and I think (math.e, (0/2.25)) is missing a function call (probably math.pow, but thats just a wild guess).

If you want to add a new record in the form

newRecord = [4L, 1L, u'DDD', 1689544L, datetime.datetime(2010, 9, 21, 21, 45), u'jhhjjh']

to messageName where messageName in the form X_somemessage can, but does not have to be in your dictionary, then do it this way:

myDict.setdefault(messageName, []).append(newRecord)

This way it will be appended to an existing messageName or a new list will be created for a new messageName.

For those of you who are using the Data Binding Library, to get the root of the current activity, simply use:

View rootView = dataBinding.getRoot();

And for Kotlin users, it's even simpler:

val rootView = dataBinding.root

For example :

In MainActivity :

Intent intent = new Intent(this, OtherActivity.class);
intent.putExtra(OtherActivity.KEY_EXTRA, yourDataObject);
startActivity(intent);

In OtherActivity :

public static final String KEY_EXTRA = "com.example.yourapp.KEY_BOOK";

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  String yourDataObject = null;

  if (getIntent().hasExtra(KEY_EXTRA)) {
      yourDataObject = getIntent().getStringExtra(KEY_EXTRA);
  } else {
      throw new IllegalArgumentException("Activity cannot find  extras " + KEY_EXTRA);
  }
  // do stuff
}

More informations here : http://developer.android.com/reference/android/content/Intent.html

To get the fields info too, you can use the following:

SELECT TABLE_SCHEMA, TABLE_NAME, 
       COLUMN_NAME, substring(DATA_TYPE, 1,1) AS DATA_TYPE
FROM information_schema.COLUMNS 
WHERE TABLE_SCHEMA NOT IN("information_schema", "mysql", "performance_schema") 
ORDER BY TABLE_SCHEMA, TABLE_NAME, ORDINAL_POSITION

Just made this.. it will print files and directory in hierarchical way

But I didn't used fnmatch or walk

#!/usr/bin/python

import os,glob,sys

def dirlist(path, c = 1):

        for i in glob.glob(os.path.join(path, "*")):
                if os.path.isfile(i):
                        filepath, filename = os.path.split(i)
                        print '----' *c + filename

                elif os.path.isdir(i):
                        dirname = os.path.basename(i)
                        print '----' *c + dirname
                        c+=1
                        dirlist(i,c)
                        c-=1


path = os.path.normpath(sys.argv[1])
print(os.path.basename(path))
dirlist(path)

We can use TRUNC function in Oracle DB. Here is an example.

SELECT TRUNC(TO_DATE('01 Jan 2018 08:00:00','DD-MON-YYYY HH24:MI:SS')) FROM DUAL

Output: 1/1/2018

You need the link inside to be clickable, meaning it needs a href with some content, and also, close() is a built-in function of window, so you need to change the name of the function to avoid a conflict.

<div id="upbutton"><a href="#" onclick="close2()">click to close</a></div>

Also if you want a real "button" instead of a link, you should use <input type="button"/> or <button/>.

Try this

Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
String userName = authentication.getName();

You should use ContextWrapper like this:

ContextWrapper cw = new ContextWrapper(context);
File directory = cw.getDir("media", Context.MODE_PRIVATE);

As always, refer to documentation, ContextWrapper has a lot to offer.

I am doing this on click of Button.

private static final int CAMERA_PIC_REQUEST = 1;

private View.OnClickListener  OpenCamera=new View.OnClickListener() {

            @Override
            public void onClick(View paramView) {
                // TODO Auto-generated method stub

                Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

                NewSelectedImageURL=null;
                //outfile where we are thinking of saving it
                Date date = new Date();
                SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH-mm-ss");

                String newPicFile = RecipeName+ df.format(date) + ".png";


                String outPath =Environment.getExternalStorageDirectory() + "/myFolderName/"+ newPicFile ;
                File outFile = new File(outPath);               

                CapturedImageURL=outFile.toString();
                Uri outuri = Uri.fromFile(outFile);
                cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, outuri);            
                startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);  

            }
        };

You can get the URL of the recently Captured Image from variable CapturedImageURL

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


    //////////////////////////////////////
    if (requestCode == CAMERA_PIC_REQUEST) {  
        // do something  

         if (resultCode == RESULT_OK) 
         {
             Uri uri = null;

             if (data != null) 
             {
                 uri = data.getData();
             }
             if (uri == null && CapturedImageURL != null) 
             {
                 uri = Uri.fromFile(new File(CapturedImageURL));
             }
             File file = new File(CapturedImageURL);
             if (!file.exists()) {
                file.mkdir();
                sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"+Environment.getExternalStorageDirectory())));
            }




         }


    }

Old thread but for me it started working (after following all advise above) when i renamed int main(void) to int wmain(void) and removed WIN23 from cmake's add_executable().

date only work with GNU date (usually comes with Linux)

for OS X, two choices:

1. change command (verified)

   #!/bin/sh
   #DATE=20090801204150
   #date -jf "%Y%m%d%H%M%S" $DATE "+date \"%A,%_d %B %Y %H:%M:%S\""
   date "Saturday, 1 August 2009 20:41:50"

Why not use tabs (introduced in Vim 7)? You can switch between tabs with :tabn and :tabp, With :tabe <filepath> you can add a new tab; and with a regular :q or :wq you close a tab. If you map :tabn and :tabp to your F7/F8 keys you can easily switch between files.

If there are not that many files or you don't have Vim 7 you can also split your screen in multiple files: :sp <filepath>. Then you can switch between splitscreens with Ctrl+W and then an arrow key in the direction you want to move (or instead of arrow keys, w for next and W for previous splitscreen)

Unless you have a special situation that requires a non thread-pool thread, just use a thread pool thread like this:

Action secondFooAsync = new Action(SecondFoo);

secondFooAsync.BeginInvoke(new AsyncCallback(result =>
      {
         (result.AsyncState as Action).EndInvoke(result); 

      }), secondFooAsync); 

Gaurantees that EndInvoke is called to take care of the clean up for you.

I faced the issue with my web application based on Spring 3 and deployed on Weblogic 10.3 on Oracle Linux 6. The solution mentioned at the link did not work for me.

I had to take the following steps - 1. Copy the Arial*.ttf font files to JROCKIT_JAVA_HOME/jre/lib/fonts directory 2. Make entries of the fonts in fontconfig.properties.src 3. Restart the cluster from Weblogic console

filename.Arial=Arial.ttf
filename.Arial_Bold=Arial_Bold.ttf
filename.Arial_Italic=Arial_Italic.ttf
filename.Arial_Bold_Italic=Arial_Bold_Italic.ttf

There are two cases:

1. If you are having a single image, irrespective of device version, then you should put your images in drawable folder.

2. But for the images that you created separately for hdpi, ldpi, mdpi, xhdpi, xxhdpi and xxxhdpi, depending on screen resolution of the mobile that will be using the app, you have to puy them in drawable-hdpi, drawable-ldpi, drawable-mdpi, drawable-xhdpi, drawable-xxhdpi and drawable-xxxhdpi folders respectively.

For the first case, if there is a single image, you can pretty much place it in any drawable folder, but its standard convention to put them in drawable folder.

<ItemTemplate>
     <asp:Button ID="Button1" runat="server" Text="Button" 
            OnClick="MyButtonClick" />
</ItemTemplate>

and your method

 protected void MyButtonClick(object sender, System.EventArgs e)
{
     //Get the button that raised the event
Button btn = (Button)sender;

    //Get the row that contains this button
GridViewRow gvr = (GridViewRow)btn.NamingContainer;
}

First try this: dont use the php composer.phar [parameters] simply use composer [parameters] if this doesn't work for you than try the rest. Hope it helps.

I guess the following code will help:

var refreshIntervalId = setInterval(fname, 10000);

clearInterval(refreshIntervalId);

You did the code 100% correct... So... What's the problem? Or it's a tutorial...

From Windows Vista on you have the TIMEOUT and SLEEP commands, but to use them on Windows XP or Windows Server 2003, you'll need the Windows Server 2003 resource tool kit.

Here you have a good overview of sleep alternatives (the ping approach is the most popular as it will work on every Windows machine), but there's (at least) one not mentioned which (ab)uses the W32TM (Time Service) command:

w32tm /stripchart /computer:localhost /period:1 /dataonly /samples:N  >nul 2>&1

Where you should replace the N with the seconds you want to pause. Also, it will work on every Windows system without prerequisites.

Typeperf can also be used:

typeperf "\System\Processor Queue Length" -si N -sc 1 >nul

With mshta and javascript (can be used for sleep under a second):

start "" /wait /min /realtime mshta "javascript:setTimeout(function(){close();},5000)"

This should be even more precise (for waiting under a second) - self compiling executable relying on .net:

::
::

Here is one way to test which YAML implementation the user has selected on the virtualenv (or the system) and then define load_yaml_file appropriately:

load_yaml_file = None

if not load_yaml_file:
    try:

        load_yaml_file = lambda fn: yaml.load(open(fn))
    except:

        def load_yaml_file(fn):
            ruby = "puts YAML.load_file('%s').to_json" % fn
            j = commands.getstatusoutput('ruby -ryaml -rjson -e "%s"' % ruby)
            return json.loads(j[1])

if not load_yaml_file:
    import os, sys
    print """

It's actually quite easy, assuming you have an openssl installation handy. (What platform are you on?)

Assuming you're on linux/solaris/mac os/x, Van's Apache SSL/TLS mini-HOWTO has an excellent walkthrough that I won't reproduce here.

However, the executive summary is that you have to create a self-signed certificate. Since you're running apache for localhost presumably for development (i.e. not a public web server), you'll know that you can trust the self-signed certificate and can ignore the warnings that your browser will throw at you.

The above answers work fine too, but I've found you can usually just use message.author.send("blah blah") instead of message.author.sendMessage("blah blah").

-EDIT- : This is because the sendMessage command is outdated as of v12 in Discord Js

.send tends to work better for me in general than .sendMessage, which sometimes runs into problems. Hope that helps a teeny bit!

This does not work in Chrome Developer tools to locate a element, i am looking to locate the 'Submit' button in the screen

//input[matches(@value,'submit','i')]

However, using 'translate' to replace all caps to small works as below

//input[translate(@value,'ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghijklmnopqrstuvwxyz') = 'submit']

Update: I just found the reason why 'matches' doesnt work. I am using Chrome with xpath 1.0 which wont understand the syntax 'matches'. It should be xpath 2.0

I tried the @Alexander Farber and @Sino Raj answers. Both answers are nice, but I couldn't use the onCreateOptionsMenu inside my fragment, until I discover what was missing:

Add setSupportActionBar(toolbar) in my Activity, like this:

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

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
}

I hope this answer can be helpful for someone with the same problem.

After a few hours of messing around I eventually got something that works, partially answered in a similar issue here: How do I include a JavaScript file in another JavaScript file?

BUT there was an import that was screwing the rest of it up:

Use require in .vue files

<script>
  var mylib = require('./mylib');
  export default {
  ....

Exports in mylib

 exports.myfunc = () => {....}

Avoid import

The actual issue in my case (which I didn't think was relevant!) was that mylib.js was itself using other dependencies. The resulting error seems to have nothing to do with this, and there was no transpiling error from webpack but anyway I had:

import models from './model/models'
import axios from 'axios'

This works so long as I'm not using mylib in a .vue component. However as soon as I use mylib there, the error described in this issue arises.

I changed to:

let models = require('./model/models');
let axios = require('axios');

And all works as expected.

I find it easier to access it by doing the following:

        for (int i = 0; i < Table.Rows.Count-1; i++) //Looping through rows
        {
            var myValue = Table.Rows[i]["MyFieldName"]; //Getting my field value

        }

Using res.json with Express:

function random(response) {
  console.log("response.json sets the appropriate header and performs JSON.stringify");
  response.json({ 
    anObject: { item1: "item1val", item2: "item2val" }, 
    anArray: ["item1", "item2"], 
    another: "item"
  });
}

Alternatively:

function random(response) {
  console.log("Request handler random was called.");
  response.writeHead(200, {"Content-Type": "application/json"});
  var otherArray = ["item1", "item2"];
  var otherObject = { item1: "item1val", item2: "item2val" };
  var json = JSON.stringify({ 
    anObject: otherObject, 
    anArray: otherArray, 
    another: "item"
  });
  response.end(json);
}

You can also use the Cookies API and do:

browser.cookies.set({
  url: 'example.com',
  name: 'HelloWorld',
  value: 'HelloWorld',
  expirationDate: myDate
}

MDN Set() Method Documentation

After Redis 2.6, the result of INFO command are splitted by sections. In the "keyspace" section, there are "keys" and "expired keys" fields to tell how many keys are there.

Add !important rule to display: table of your .v-center class.

.v-center {
    display:table !important;
    border:2px solid gray;
    height:300px;
}

Your display property is being overridden by bootstrap to display: block.

Example

To answer your first question... .format just seems more sophisticated in many ways. An annoying thing about % is also how it can either take a variable or a tuple. You'd think the following would always work:

"hi there %s" % name

yet, if name happens to be (1, 2, 3), it will throw a TypeError. To guarantee that it always prints, you'd need to do

"hi there %s" % (name,)   # supply the single argument as a single-item tuple

which is just ugly. .format doesn't have those issues. Also in the second example you gave, the .format example is much cleaner looking.

Why would you not use it?

• not knowing about it (me before reading this)
• having to be compatible with Python 2.5

To answer your second question, string formatting happens at the same time as any other operation - when the string formatting expression is evaluated. And Python, not being a lazy language, evaluates expressions before calling functions, so in your log.debug example, the expression "some debug info: %s"%some_infowill first evaluate to, e.g. "some debug info: roflcopters are active", then that string will be passed to log.debug().

In the example in the code you have posted there is, in fact, no point in catching the exception as there is nothing done on the catch it is just re-thown, in fact it does more harm than good as the call stack is lost.

You would, however catch an exception to do some logic (for example closing sql connection of file lock, or just some logging) in the event of an exception the throw it back to the calling code to deal with. This would be more common in a business layer than front end code as you may want the coder implementing your business layer to handle the exception.

To re-iterate though the There is NO point in catching the exception in the example you posted. DON'T do it like that!

If you need the highlighted tint which the OS provides by default when you tap and hold on a custom button for the selected state as well, use this UIButton subclass. Written in Swift 5:

import Foundation
import UIKit
class HighlightOnSelectCustomButton: UIButton {
    override var isHighlighted: Bool {
        didSet {
            if (self.isSelected != isHighlighted) {
                self.isHighlighted = self.isSelected
            }
        }
    }
}

Using the length of the list would be the fastest solution to check if an index exists:

def index_exists(ls, i):
    return (0 <= i < len(ls)) or (-len(ls) <= i < 0)

This also tests for negative indices, and most sequence types (Like ranges and strs) that have a length.

If you need to access the item at that index afterwards anyways, it is easier to ask forgiveness than permission, and it is also faster and more Pythonic. Use try: except:.

try:
    item = ls[i]
    # Do something with item
except IndexError:
    # Do something without the item

This would be as opposed to:

if index_exists(ls, i):
    item = ls[i]
    # Do something with item
else:
    # Do something without the item

private static final int[] CDRIVES = new int[] {0xe0, 0xf4, ...};

and after access convert to byte.

When calling a constructor it actually allocates memory, either from the stack or from the heap. So calling a constructor in another constructor creates a local copy. So we are modifying another object, not the one we are focusing on.

Since R is already installed, you should be able to upgrade it with this method. First of all, you may want to have the packages you installed in the previous version in the new one,so it is convenient to check this post. Then, follow the instructions from here

1. Open the sources.list file:

    sudo nano /etc/apt/sources.list    
   

2. Add a line with the source from where the packages will be retrieved. For example:

    deb https://cloud.r-project.org/bin/linux/ubuntu/ version/
   

   Replace https://cloud.r-project.org with whatever mirror you would like to use, and replace version/ with whatever version of Ubuntu you are using (eg, trusty/, xenial/, and so on). If you're getting a "Malformed line error", check to see if you have a space between /ubuntu/ and version/.

3. Fetch the secure APT key:

    gpg --keyserver keyserver.ubuntu.com --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9
   

or

    gpg --hkp://keyserver keyserver.ubuntu.com:80 --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9

4. Add it to keyring:

    gpg -a --export E084DAB9 | sudo apt-key add -
   

5. Update your sources and upgrade your installation:

    sudo apt-get update && sudo apt-get upgrade
   

6. Install the new version

    sudo apt-get install r-base-dev
   

7. Recover your old packages following the solution that best suits to you (see this). For instance, to recover all the packages (not only those from CRAN) the idea is:

-- copy the packages from R-oldversion/library to R-newversion/library, (do not overwrite a package if it already exists in the new version!).

-- Run the R command update.packages(checkBuilt=TRUE, ask=FALSE).

You can use array_filter() which works great for all situations:

$ray_state = array_filter($myarray);

if (empty($ray_state)) {
    echo 'array is empty';
} else {
    echo 'array is not empty';
}

You can use model.predict() to predict the class of a single image as follows [doc]:

# load_model_sample.py
from keras.models import load_model
from keras.preprocessing import image
import matplotlib.pyplot as plt
import numpy as np
import os


def load_image(img_path, show=False):

    img = image.load_img(img_path, target_size=(150, 150))
    img_tensor = image.img_to_array(img)                    # (height, width, channels)
    img_tensor = np.expand_dims(img_tensor, axis=0)         # (1, height, width, channels), add a dimension because the model expects this shape: (batch_size, height, width, channels)
    img_tensor /= 255.                                      # imshow expects values in the range [0, 1]

    if show:
        plt.imshow(img_tensor[0])                           
        plt.axis('off')
        plt.show()

    return img_tensor


if __name__ == "__main__":

    # load model
    model = load_model("model_aug.h5")

    # image path
    img_path = '/media/data/dogscats/test1/3867.jpg'    # dog
    #img_path = '/media/data/dogscats/test1/19.jpg'      # cat

    # load a single image
    new_image = load_image(img_path)

    # check prediction
    pred = model.predict(new_image)

In this example, a image is loaded as a numpy array with shape (1, height, width, channels). Then, we load it into the model and predict its class, returned as a real value in the range [0, 1] (binary classification in this example).

You could also go into XCode -> Preferences, select the Indentation tab, and turn on Line Wrapping.

That way, you won't have to type anything extra, and it will work for the stuff you already wrote. :-)

One annoying thing though is...

if (you're long on indentation
    && short on windows) {
            then your code will
                end up squished
                     against th
                         e side
                             li
                              k
                              e

                              t
                              h
                              i
                              s
}

The purrr package has a lot of handy functions for working on lists. The flatten command can clean up unwanted nesting.

resultsa <- list(1,2,3,4,5)
resultsb <- list(6,7,8,9,10)
resultsc <- list(11,12,13,14,15)

nested_outlist <- list(resultsa, resultsb, resultsc)
outlist <- purrr::flatten(nested_outlist)

You can use ConnectivityManager.

val cm = getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
            val activeNetwork: NetworkInfo? = cm.activeNetworkInfo
            val dialogBuilder = AlertDialog.Builder(this)

            if (activeNetwork!=null) // Some network is available
            {
                if (activeNetwork.isConnected) { // Network is connected to internet

    }else{ // Network is NOT connected to internet

    }

In Java File

public class MainActivity extends Activity {
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main); 
        GifImageView gifImageView = (GifImageView) findViewById(R.id.gifImageView1);
        if (Build.VERSION.SDK_INT >= 11) {
            gifImageView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
        }
    }
}

We need to use gifImageView.setLayerType(View.LAYER_TYPE_SOFTWARE, null); as when hardware accelerated enabled, GIF image not work on those device. Hardware accelerated is enabled on devices above(4.x).

Here is some information about one more source of the JSESSIONID cookie:

I was just debugging some Java code that runs on a tomcat server. I was not calling request.getSession() explicitly anywhere in my code but I noticed that a JSESSIONID cookie was still being set.

I finally took a look at the generated Java code corresponding to a JSP in the work directory under Tomcat.

It appears that, whether you like it or not, if you invoke a JSP from a servlet, JSESSIONID will get created!

Added: I just found that by adding the following JSP directive:

<%@ page session="false" %>

you can disable the setting of JSESSIONID by a JSP.

Depends on where the file you are trying to include from is located.

Example:

/rootdir/pages/file.php

/someotherDir/index.php

If you wrote the following in index.php: include('/rootdir/pages/file.php');it would error becuase it would try to get:

/someotherDir/rootdir/pages/file.php Which of course doesn't exist...

So you would have to use include('../rootdir/pages/file.php');

As hadley mentioned there are more effective ways of communicating your message than labels in stacked bar charts. In fact, stacked charts aren't very effective as the bars (each Category) doesn't share an axis so comparison is hard.

It's almost always better to use two graphs in these instances, sharing a common axis. In your example I'm assuming that you want to show overall total and then the proportions each Category contributed in a given year.

library(grid)
library(gridExtra)
library(plyr)

# create a new column with proportions
prop <- function(x) x/sum(x)
Data <- ddply(Data,"Year",transform,Share=prop(Frequency))

# create the component graphics
totals <- ggplot(Data,aes(Year,Frequency)) + geom_bar(fill="darkseagreen",stat="identity") + 
  xlab("") + labs(title = "Frequency totals in given Year")
proportion <- ggplot(Data, aes(x=Year,y=Share, group=Category, colour=Category)) 
+ geom_line() + scale_y_continuous(label=percent_format())+ theme(legend.position = "bottom") + 
  labs(title = "Proportion of total Frequency accounted by each Category in given Year")

# bring them together
grid.arrange(totals,proportion)

This will give you a 2 panel display like this:

If you want to add Frequency values a table is the best format.

You are getting the WebView before setting the Content view so the wv is probably null.

public class ViewWeb extends Activity {  
        @Override  
        public void onCreate(Bundle savedInstanceState) {  
            super.onCreate(savedInstanceState);
            setContentView(R.layout.webview);  
            WebView wv;  
            wv = (WebView) findViewById(R.id.webView1);  
            wv.loadUrl("file:///android_asset/aboutcertified.html");   // now it will not fail here
        }  
    }

I was running Eclipse Neon.2 and the Android SDK Build-tools + platform-tools version 26 on Mac OS 10.12.4 and none of the above answers (including the accepted answer) worked for me.

What did work was to

1. Quit Eclipse

2. Remove the folder <android-sdk>/build-tools/26.0.0 and to install the (older) version 25.0.3 of the build tools through the Android SDK manager.

3. Start Eclipse again

For me, this used to work, but upgrading libraries caused this issue to appear. Problem was having a class like this:

package example.counter;

import javax.validation.constraints.NotNull;

import lombok.Data;

@Data
public class CounterRequest {
    @NotNull
    private final Integer int1;

    @NotNull
    private final Integer int2;
}

Using lombok:

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.0</version>
</dependency>

Falling back to

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.16.10</version>
</dependency>

Fixed the issue. Not sure why, but wanted to document it for future.

The question is about a non rooted device but if it is rooted the simplest way would be to:

From the terminal on your phone, do this:

su
setprop service.adb.tcp.port 5555
stop adbd
start adbd

See this answer for full details.

If you are using Maven you may have both src/{main,test}/resources/META-INF/persistence.xml. This is a common setup: test your JPA code with h2 or Derby and deploy it with PostgreSQL or some other full DBMS. If you're using this pattern, do make sure the two files have different unit names, else some versions of the Persistence class will try to load BOTH (because of course your test-time CLASSPATH includes both classes and test-classes); this will cause conflicting definitions of the persistence unit, resulting in the dreaded annoying message that we all hate so much!

Worse: this may "work" with some older versions of e.g., Hibernate, but fail with current versions. Worth getting it right anyway...

I think this may work.

public static byte[] StrToByteArray(string str)
    {
        Dictionary<string, byte> hexindex = new Dictionary<string, byte>();
        for (int i = 0; i <= 255; i++)
            hexindex.Add(i.ToString("X2"), (byte)i);

        List<byte> hexres = new List<byte>();
        for (int i = 0; i < str.Length; i += 2)            
            hexres.Add(hexindex[str.Substring(i, 2)]);

        return hexres.ToArray();
    }

Take a look at ?legend and try this:

legend('topright', names(a)[-1] , 
   lty=1, col=c('red', 'blue', 'green',' brown'), bty='n', cex=.75)

<a href="javascript:;" onclick="window.location = 'http://example.com/submit.php?url=' + escape(document.location.href);'">Go</a>;

Do as follows for milliseconds:

select round(date_format(CURTIME(3), "%f")/1000)

You can get microseconds by the following:

select date_format(CURTIME(6), "%f")

Use IFNULL:

IFNULL(expr1, 0)

From the documentation:

If expr1 is not NULL, IFNULL() returns expr1; otherwise it returns expr2. IFNULL() returns a numeric or string value, depending on the context in which it is used.
