There are apparently distributions or custom builds in which the ability to set Task Tags for non-Java files is not present. This post mentions that ColdFusion Builder (built on Eclipse) does not let you set non-Java Task Tags, but the beta version of CF Builder 2 does. (I know the OP wasn't using CF Builder, but I am, and I was wondering about this question myself ... because he didn't see the ability to set non-Java tags, I thought others might be in the same position.)

I know this is an old thread, but I wanted to share a solution I ended up having to use since the accepted post still has an issue.

The Issue:

As pointed out by Alexandre Severino, if param (in the function below) changes shortly after the function call, you might get some unexpected behavior in MethodWithParameter.

Task.Run(() => MethodWithParameter(param)); 

My Solution:

To account for this, I ended up writing something more like the following line of code:

(new Func<T, Task>(async (p) => await Task.Run(() => MethodWithParam(p)))).Invoke(param);

This allowed me to safely use the parameter asynchronously despite the fact that the parameter changed very quickly after starting the task (which caused issues with the posted solution).

Using this approach, param (value type) gets its value passed in, so even if the async method runs after param changes, p will have whatever value param had when this line of code ran.

A clean example that answers the Title

string output = "Error";
Task task = Task.Factory.StartNew(() =>
{
    System.Threading.Thread.Sleep(2000);
    output = "Complete";
});

task.Wait();
Console.WriteLine(output);

This is the same method I have been using for a couple of years now and I haven't seen or found anything better. As people have said, PHP is single threaded, so there isn't much else you can do.

I have actually added one extra level to this and that's getting and storing the process id. This allows me to redirect to another page and have the user sit on that page, using AJAX to check if the process is complete (process id no longer exists). This is useful for cases where the length of the script would cause the browser to timeout, but the user needs to wait for that script to complete before the next step. (In my case it was processing large ZIP files with CSV like files that add up to 30 000 records to the database after which the user needs to confirm some information.)

I have also used a similar process for report generation. I'm not sure I'd use "background processing" for something such as an email, unless there is a real problem with a slow SMTP. Instead I might use a table as a queue and then have a process that runs every minute to send the emails within the queue. You would need to be warry of sending emails twice or other similar problems. I would consider a similar queueing process for other tasks as well.

Real-time is the highest priority class available to a process. Therefore, it is different from 'High' in that it's one step greater, and 'Above Normal' in that it's two steps greater.

Similarly, real-time is also a thread priority level.

The process priority class raises or lowers all effective thread priorities in the process and is therefore considered the 'base priority'.

So, a process has a:

1. Base process priority class.
2. Individual thread priorities, offsets of the base priority class.

Since real-time is supposed to be reserved for applications that absolutely must pre-empt other running processes, there is a special security privilege to protect against haphazard use of it. This is defined by the security policy.

In NT6+ (Vista+), use of the Vista Multimedia Class Scheduler is the proper way to achieve real-time operations in what is not a real-time OS. It works, for the most part, though is not perfect since the OS isn't designed for real-time operations.

Microsoft considers this priority very dangerous, rightly so. No application should use it except in very specialized circumstances, and even then try to limit its use to temporary needs.

The best way is to use fixtures.

Note: Keep in mind that fixtures do direct inserts and don't use your model so if you have callbacks that populate data you will need to find a workaround.

This is called fire and forget, and there is an extension for that.

Consumes a task and doesn't do anything with it. Useful for fire-and-forget calls to async methods within async methods.

Install nuget package.

Use:

MyAsyncMethod().Forget();

Usually you hear Task is a higher level concept than thread... and that's what this phrase means:

1. You can't use Abort/ThreadAbortedException, you should support cancel event in your "business code" periodically testing token.IsCancellationRequested flag (also avoid long or timeoutless connections e.g. to db, otherwise you will never get a chance to test this flag). By the similar reason Thread.Sleep(delay) call should be replaced with Task.Delay(delay, token) call (passing token inside to have possibility to interrupt delay).

2. There are no thread's Suspend and Resume methods functionality with tasks. Instance of task can't be reused either.

3. But you get two new tools:

   a) continuations

   // continuation with ContinueWhenAll - execute the delegate, when ALL
   // tasks[] had been finished; other option is ContinueWhenAny
   
   Task.Factory.ContinueWhenAll( 
      tasks,
      () => {
          int answer = tasks[0].Result + tasks[1].Result;
          Console.WriteLine("The answer is {0}", answer);
      }
   );
   

   b) nested/child tasks

   //StartNew - starts task immediately, parent ends whith child
   var parent = Task.Factory.StartNew
   (() => {
             var child = Task.Factory.StartNew(() =>
            {
            //...
            });
         },  
         TaskCreationOptions.AttachedToParent
   );
   

4. So system thread is completely hidden from task, but still task's code is executed in the concrete system thread. System threads are resources for tasks and ofcourse there is still thread pool under the hood of task's parallel execution. There can be different strategies how thread get new tasks to execute. Another shared resource TaskScheduler cares about it. Some problems that TaskScheduler solves 1) prefer to execute task and its conitnuation in the same thread minimizing switching cost - aka inline execution) 2) prefer execute tasks in an order they were started - aka PreferFairness 3) more effective distribution of tasks between inactive threads depending on "prior knowledge of tasks activity" - aka Work Stealing. Important: in general "async" is not same as "parallel". Playing with TaskScheduler options you can setup async tasks be executed in one thread synchronously. To express parallel code execution higher abstractions (than Tasks) could be used: Parallel.ForEach, PLINQ, Dataflow.

5. Tasks are integrated with C# async/await features aka Promise Model, e.g there requestButton.Clicked += async (o, e) => ProcessResponce(await client.RequestAsync(e.ResourceName)); the execution of client.RequestAsync will not block UI thread. Important: under the hood Clicked delegate call is absolutely regular (all threading is done by compiler).

That is enough to make a choice. If you need to support Cancel functionality of calling legacy API that tends to hang (e.g. timeoutless connection) and for this case supports Thread.Abort(), or if you are creating multithread background calculations and want to optimize switching between threads using Suspend/Resume, that means to manage parallel execution manually - stay with Thread. Otherwise go to Tasks because of they will give you easy manipulate on groups of them, are integrated into the language and make developers more productive - Task Parallel Library (TPL) .

One issue with your ContentLoader is that internally it operates sequentially. A better pattern is to parallelize the work and then sychronize at the end, so we get

public class PageViewModel : IHandle<SomeMessage>
{
   ...

   public async void Handle(SomeMessage message)
   {
      ShowLoadingAnimation();

      // makes UI very laggy, but still not dead
      await this.contentLoader.LoadContentAsync(); 

      HideLoadingAnimation();   
   }
}

public class ContentLoader 
{
    public async Task LoadContentAsync()
    {
        var tasks = new List<Task>();
        tasks.Add(DoCpuBoundWorkAsync());
        tasks.Add(DoIoBoundWorkAsync());
        tasks.Add(DoCpuBoundWorkAsync());
        tasks.Add(DoSomeOtherWorkAsync());

        await Task.WhenAll(tasks).ConfigureAwait(false);
    }
}

Obviously, this doesn't work if any of the tasks require data from other earlier tasks, but should give you better overall throughput for most scenarios.

In addition to @takemyoxygen's answer the convention of having a function name that ends in Async is that this function is truly asynchronous. I.e. it does not start a new thread and it doesn't simply call Task.Run. If that is all the code that is in your function, it will be better to remove it completely and simply have:

List<Item> list = await Task.Run(() => manager.GetList());

From SDK:

Cancelling a task

A task can be cancelled at any time by invoking cancel(boolean). Invoking this method will cause subsequent calls to isCancelled() to return true.

After invoking this method, onCancelled(Object), instead of onPostExecute(Object) will be invoked after doInBackground(Object[]) returns.

To ensure that a task is cancelled as quickly as possible, you should always check the return value of isCancelled() periodically from doInBackground(Object[]), if possible (inside a loop for instance.)

So your code is right for dialog listener:

uploadingDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
    public void onCancel(DialogInterface dialog) {
        myTask.cancel(true);
        //finish();
    }
});

Now, as I have mentioned earlier from SDK, you have to check whether the task is cancelled or not, for that you have to check isCancelled() inside the onPreExecute() method.

For example:

if (isCancelled()) 
    break;
else
{
   // do your work here
}

In Celery 3+:

CLI:

$ celery -A proj purge

Programatically:

>>> from proj.celery import app
>>> app.control.purge()

http://docs.celeryproject.org/en/latest/faq.html#how-do-i-purge-all-waiting-tasks

You can't. Tasks use background threads from the thread pool. Also canceling threads using the Abort method is not recommended. You may take a look at the following blog post which explains a proper way of canceling tasks using cancellation tokens. Here's an example:

class Program
{
    static void Main()
    {
        var ts = new CancellationTokenSource();
        CancellationToken ct = ts.Token;
        Task.Factory.StartNew(() =>
        {
            while (true)
            {
                // do some heavy work here
                Thread.Sleep(100);
                if (ct.IsCancellationRequested)
                {
                    // another thread decided to cancel
                    Console.WriteLine("task canceled");
                    break;
                }
            }
        }, ct);

        // Simulate waiting 3s for the task to complete
        Thread.Sleep(3000);

        // Can't wait anymore => cancel this task 
        ts.Cancel();
        Console.ReadLine();
    }
}

I just wanted to add this version because this is such a useful thread and I think this is a very simple implementation. I have used this multiple times in various types if multithreaded application:

 Task.Factory.StartNew(() =>
      {
        DoLongRunningWork();
        Application.Current.Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(() =>
              { txt.Text = "Complete"; }));
      });

When setup a job in new windows you have two fields "program/script" and "Start in(Optional)". Put program name in first and program location in second. If you will not do that and your program start not in directory with exe, it will not find files that are located in it.

Use Platform.runLater(...) for quick and simple operations and Task for complex and big operations .

• Use case for Platform.runLater(...)
• Use case for Task: Task Example in Ensemble App

Example: Why Can't we use Platform.runLater(...) for long calculations (Taken from below reference).

Problem: Background thread which just counts from 0 to 1 million and update progress bar in UI.

Code using Platform.runLater(...):

final ProgressBar bar = new ProgressBar();
new Thread(new Runnable() {
    @Override public void run() {
    for (int i = 1; i <= 1000000; i++) {
        final int counter = i;
        Platform.runLater(new Runnable() {
            @Override public void run() {
                bar.setProgress(counter / 1000000.0);
            }
        });
    }
}).start();

This is a hideous hunk of code, a crime against nature (and programming in general). First, you’ll lose brain cells just looking at this double nesting of Runnables. Second, it is going to swamp the event queue with little Runnables — a million of them in fact. Clearly, we needed some API to make it easier to write background workers which then communicate back with the UI.

Code using Task :

Task task = new Task<Void>() {
    @Override public Void call() {
        static final int max = 1000000;
        for (int i = 1; i <= max; i++) {
            updateProgress(i, max);
        }
        return null;
    }
};

ProgressBar bar = new ProgressBar();
bar.progressProperty().bind(task.progressProperty());
new Thread(task).start();

it suffers from none of the flaws exhibited in the previous code

Reference : Worker Threading in JavaFX 2.0

        if (File.Exists(fpath))
        {

            var data = File.ReadLines(fpath);
            Console.WriteLine(data.ToArray()[14]);
        }

Assuming you are writing a bootloader or other application that has access to the BIOS, here is a rough sketch of what you can do:

• Isolate the first digit of the hex byte
• If it is greater than 9 (i.e. 0x0A to 0x0F), subtract 10 from it (scaling it down to 0 to 5), and add 'A' (0x41).
• If it is less than or equal to 9 (i.e. 0x00 to 0x09), add '0' to it.
• Repeat this with the next hex digit.

Here is my implementation of this:

; Prints AL in hex.
printhexb:
    push ax
    shr al, 0x04
    call print_nibble
    pop ax
    and al, 0x0F
    call print_nibble
    ret
print_nibble:
    cmp al, 0x09
    jg .letter
    add al, 0x30
    mov ah, 0x0E
    int 0x10
    ret
.letter:
    add al, 0x37
    mov ah, 0x0E
    int 0x10
    ret   

It's impossible. You can only find and access views that are currently running. If you want to check the value of ex. TextView used in previus activity you must save the value is SharedPreferences, database, file or pass by Intent.

"Segmentation fault" means that you tried to access memory that you do not have access to.

The first problem is with your arguments of main. The main function should be int main(int argc, char *argv[]), and you should check that argc is at least 2 before accessing argv[1].

Also, since you're passing in a float to printf (which, by the way, gets converted to a double when passing to printf), you should use the %f format specifier. The %s format specifier is for strings ('\0'-terminated character arrays).

Hope this helps .

Well, here is my "answer". It uses the fact that String.Split can be told hold many items it should split to (which I found lacking in the other answers):

string theString = "Some Very Large String Here";
var array = theString.Split(new [] { ' ' }, 2); // return at most 2 parts
// note: be sure to check it's not an empty array
string firstElem = array[0];
// note: be sure to check length first
string restOfArray = array[1];

This is very similar to the Substring method, just by a different means.

you can do:

A = randi(10, [3 4]);      %# a random matrix
any( A(:)==5 )             %# does A contain 5?

To do the above in a vectorized way, use:

any( bsxfun(@eq, A(:), [5 7 11] )

or as @woodchips suggests:

ismember([5 7 11], A)

Given exportPath and queryResults as String variables, the following block creates a results.zip file under exportPath and writes the content of queryResults to a results.txt file inside the zip.

URI uri = URI.create("jar:file:" + exportPath + "/results.zip");
Map<String, String> env = Collections.singletonMap("create", "true");

try (FileSystem zipfs = FileSystems.newFileSystem(uri, env)) {
  Path filePath = zipfs.getPath("/results.txt");
  byte[] fileContent = queryResults.getBytes();

  Files.write(filePath, fileContent, StandardOpenOption.CREATE);
}

I had the exact same issue, after rightly have configured in Mac OSX host a SharedFolder with Auto-Mount enabled. On the Guest OS, it is also required to install VirtualBox Guest Additions. For the case of Windows, it is:

VBoxWindowsAdditions.exe

Right after this installation, i could perfectly view the shared folder content under This PC and Network ("\VBOXSVR\Installers").

If you use clearRect only, if you have it in a form to submit your drawing, you'll get a submit instead the clearing, or maybe it can be cleared first and then upload a void drawing, so you'll need to add a preventDefault at the beggining of the function:

   function clearCanvas(canvas,ctx) {
        event.preventDefault();
        ctx.clearRect(0, 0, canvas.width, canvas.height);

Just for clarification, CorFlags.exe is part of the .NET Framework SDK. I have the development tools on my machine, and the simplest way for me determine whether a DLL is 32-bit only is to:

1. Open the Visual Studio Command Prompt (In Windows: menu Start/Programs/Microsoft Visual Studio/Visual Studio Tools/Visual Studio 2008 Command Prompt)

2. CD to the directory containing the DLL in question

3. Run corflags like this: corflags MyAssembly.dll

You will get output something like this:

Microsoft (R) .NET Framework CorFlags Conversion Tool.  Version  3.5.21022.8
Copyright (c) Microsoft Corporation.  All rights reserved.

Version   : v2.0.50727
CLR Header: 2.5
PE        : PE32
CorFlags  : 3
ILONLY    : 1
32BIT     : 1
Signed    : 0

As per comments the flags above are to be read as following:

• Any CPU: PE = PE32 and 32BIT = 0
• x86: PE = PE32 and 32BIT = 1
• 64-bit: PE = PE32+ and 32BIT = 0

Basically, tree conflicts arise if there is some restructure in the folder structure on the branch. You need to delete the conflict folder and use svn clean once. Hope this solves your conflict.

JavaScript code using ng-controller:

$scope.checkkey = function (event) {
  alert(event.keyCode);  //this will show the ASCII value of the key pressed

}

In HTML:

<input type="text" ng-keypress="checkkey($event)" />

You can now place your checks and other conditions using the keyCode method.

Use this code:

'{:x}'.format(int(line))

it allows you to specify a number of digits too:

'{:06x}'.format(123)
# '00007b'

For Python 2.6 use

'{0:x}'.format(int(line))

or

'{0:06x}'.format(int(line))

The top voted answer is deprecated in Bootstrap 3.3 and will be removed in v4. Try this instead:

While both reducebykey and groupbykey will produce the same answer, the reduceByKey example works much better on a large dataset. That's because Spark knows it can combine output with a common key on each partition before shuffling the data.

On the other hand, when calling groupByKey - all the key-value pairs are shuffled around. This is a lot of unnessary data to being transferred over the network.

Ok, here 's my answer. The method that fixes the ListView height is closed enough, but not perfect. In case that most of the items are the same height, that work well. But in case that's not, then there's a big problem. I've tried many time, and when I put out the value of listItem.getMeasureHeight and listItem.getMeasuerWidth into the log, I saw the width values vary a lot, which is not expected here, since all the item in the same ListView should have the same width. And there go the bug :

Some used measure(0 ,0), which actually made the view unbound, in both direction, and width run wild. Some tried to getWidth of listView, but then it return 0, meaningless.

When I read further into how android render the View, I realize that all of this attempt can't reach the answer that I searched for, unless these function run after the view is render.

This time I use the getViewTreeObserver on the ListView that I want to fix height, then addOnGlobalLayoutListener. Inside this method, I declare a new OnGlobalLayoutListener, in which, this time, getWidth return the actual width of the ListView.

private void getLayoutWidth(final ListView lv, final int pad){
        //final ArrayList<Integer> width = new ArrayList<Integer>();

        ViewTreeObserver vto = lv.getViewTreeObserver();
        vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                lv.getViewTreeObserver().removeOnGlobalLayoutListener(this);
                //width.add(layout.getMeasuredWidth());
                int width = lv.getMeasuredWidth();
                ListUtils.setDynamicHeight(lv, width, pad);
            }
        });
    }

public static class ListUtils {
        //private static final int UNBOUNDED = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
        public static void setDynamicHeight(ListView mListView, int width, int pad) {
            ListAdapter mListAdapter = mListView.getAdapter();
            mListView.getParent();
            if (mListAdapter == null) {
                // when adapter is null
                return;
            }
            int height = 0;


            int desiredWidth = View.MeasureSpec.makeMeasureSpec(width - 2*pad, View.MeasureSpec.EXACTLY);
            for (int i = 0; i < mListAdapter.getCount(); i++) {
                View listItem = mListAdapter.getView(i, null, mListView);

                listItem.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED);
                //listItem.measure(UNBOUNDED, UNBOUNDED);
                height += listItem.getMeasuredHeight() + 2*pad;
                Log.v("ViewHeight :", mListAdapter.getClass().toString() + " " + listItem.getMeasuredHeight() + "--" + listItem.getMeasuredWidth());
            }
            ViewGroup.LayoutParams params = mListView.getLayoutParams();
            params.height = height + (mListView.getDividerHeight() * (mListAdapter.getCount() - 1));
            mListView.setLayoutParams(params);
            mListView.requestLayout();
        }
    }

The value pad, is the padding that I set in ListView layout.

Here's a solution to your problem using dplyr's filter function.

Although you can pass your data frame as the first argument to any dplyr function, I've used its %>% operator, which pipes your data frame to one or more dplyr functions (just filter in this case).

Once you are somewhat familiar with dplyr, the cheat sheet is very handy.

> print(df <- data.frame(sub=rep(1:3, each=4), day=1:4))
   sub day
1    1   1
2    1   2
3    1   3
4    1   4
5    2   1
6    2   2
7    2   3
8    2   4
9    3   1
10   3   2
11   3   3
12   3   4
> print(df <- df %>% filter(!((sub==1 & day==2) | (sub==3 & day==4))))
   sub day
1    1   1
2    1   3
3    1   4
4    2   1
5    2   2
6    2   3
7    2   4
8    3   1
9    3   2
10   3   3

In order to send data from child component create property decorated with output() in child component and in the parent listen to the created event. Emit this event with new values in the payload when ever it needed.

@Output() public eventName:EventEmitter = new EventEmitter();

to emit this event:

this.eventName.emit(payloadDataObject);

OK, we have got something called Intl which is very useful for formatting a date in JavaScript these days:

Your date as below:

var date = '10/8/2010';

And you change to Date by using new Date() like below:

date = new Date(date);

And now you can format it any way you like using a list of locales like below:

date = new Intl.DateTimeFormat('en-AU').format(date); // Australian date format: "8/10/2010" 

date = new Intl.DateTimeFormat('en-US').format(date); // USA date format: "10/8/2010" 

date = new Intl.DateTimeFormat('ar-EG').format(date);  // Arabic date format: "??/???/????"

If you exactly want the format you mentioned above, you can do:

date = new Date(Date.UTC(2010, 7, 10, 0, 0, 0));
var options = {year: "numeric", month: "short", day: "numeric"};
date = new Intl.DateTimeFormat("en-AU", options).format(date).replace(/\s/g, '-');

And the result is going to be:

"10-Aug-2010"

For more see the Intl API and Intl.DateTimeFormat documentation.

Should you want what is exactly specified in the web page, just use:

document.querySelector('head base')['href']

As noted by jitter, the $.ajax function serializes any object/array used as the data parameter into a url-encoded format. Oddly enough, the dataType parameter only applies to the response from the server - and not to any data in the request.

After encountering the same problem I downloaded and used the jquery-json plugin to correctly encode the request data to the ScriptService. Then, used the $.toJSON function to encode the desired arguments to send to the server:

$.ajax({
    type: "POST",
    url: "EditUserProfile.aspx/DeleteRecord",
    data: $.toJSON(obj),
    contentType: "application/json; charset=utf-8",
    dataType: "json"
    ....
});

qImageView.setImageResource(R.drawable.img2);

I think this will help you

HISTTIMEFORMAT="%d/%m/%y %H:%M "

For any commands typed prior to this, it will not help since they will just get a default time of when you turned history on, but it will log the time of any further commands after this.

If you want it to log history for permanent, you should put the following line in your ~/.bashrc

export HISTTIMEFORMAT="%d/%m/%y %H:%M "

Since August 2018 showinfo and rel parameter doesn't work so answers which recommend to use them no longer works and modestbranding do not remove all logos

here is my tricky solution how to hide EVERYTHING

1. Before you start you should realize that all youtube's info are sticks to the top and bottom of iframe(not video, that's important)

2. Make iframe higher than real video height. In iframe parameters set height = width * 1.7 (or other multiplicator)

3. Hide youtube's info under your header and footer with an absolute position at top and bottom of iframe wrapper element. Height of header and footer could be calculated as: iframeHeight - (iframeWidth * (9 / 16))) / 2. If you want fullscreen than you should hide it outside screen visible zone and set overflow to hidden

4. In my case I use JS to destroy iframe after video is finished so user couldn't see youtube's offer with another videos

5. Also important note: since iOS 12.2 is replacing Youtube's player by their own, width and height calculation should be done in constructor(in case of React) because iOS player arrival cause page resize ->possible width&height recalculation-> video rerender -> video pause

A disadvantage of this solution is that it stretches image placeholder.

that's how it could look like with custom controls

This example might help you. by using simple casting you can get code behind urdu character.

string str = "?????";
        char ch = ' ';
        int number = 0;
        for (int i = 0; i < str.Length; i++)
        {
            ch = str[i];
            number = (int)ch;
            Console.WriteLine(number);
        }

If you want to be able to time functions conveniently, you can use a simple decorator:

def timing_decorator(func):
    def wrapper(*args, **kwargs):
        start = time.time()
        original_return_val = func(*args, **kwargs)
        end = time.time()
        print("time elapsed in ", func.__name__, ": ", end - start, sep='')
        return original_return_val

    return wrapper

You can use it on a function that you want to time like this:

@timing_decorator
def function_to_time():
    time.sleep(1)

Then any time you call function_to_time, it will print how long it took and the name of the function being timed.

you can use default ng-submitted is set if the form was submitted.

example: http://jsbin.com/cowufugusu/1/

For simple cases like this, TimeUnit should be used. TimeUnit usage is a bit more explicit about what is being represented and is also much easier to read and write when compared to doing all of the arithmetic calculations explicitly. For example, to calculate the number days from milliseconds, the following statement would work:

    long days = TimeUnit.MILLISECONDS.toDays(milliseconds);

For cases more advanced, where more finely grained durations need to be represented in the context of working with time, an all encompassing and modern date/time API should be used. For JDK8+, java.time is now included (here are the tutorials and javadocs). For earlier versions of Java joda-time is a solid alternative.

Here's a method that I use to run a process and gets its output and errors :

public static string ShellExecute(this string path, string command, TextWriter writer, params string[] arguments)
    {
        using (var process = Process.Start(new ProcessStartInfo { WorkingDirectory = path, FileName = command, Arguments = string.Join(" ", arguments), UseShellExecute = false, RedirectStandardOutput = true, RedirectStandardError = true }))
        {
            using (process.StandardOutput)
            {
                writer.WriteLine(process.StandardOutput.ReadToEnd());
            }
            using (process.StandardError)
            {
                writer.WriteLine(process.StandardError.ReadToEnd());
            }
        }

        return path;
    }

For example :

@"E:\Temp\MyWorkingDirectory".ShellExecute(@"C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin\svcutil.exe", Console.Out);

The best way is to change any setting you want in your code.

Check out the below example:

using(WCFServiceClient client = new WCFServiceClient ())
{ 
    client.Endpoint.Binding.SendTimeout = new TimeSpan(0, 1, 30);

I'm using the J.S. to fix a sidebar menu. I've tried a lot of solutions with CSS but it's the simplest way to solve it, just add J.S. adding and removing a native BootStrap class: "position-fixed".

The J.S.:

var lateral = false;
function fixar() {

            var element, name, arr;
            element = document.getElementById("minhasidebar");

            if (lateral) {
                element.className = element.className.replace(
                        /\bposition-fixed\b/g, "");
                lateral = false;
            } else {

                name = "position-fixed";
                arr = element.className.split(" ");
                if (arr.indexOf(name) == -1) {
                    element.className += " " + name;
                }
                lateral = true;
            }

        }

The HTML:

Sidebar:

<aside>
        <nav class="sidebar ">
             <div id="minhasidebar">
                 <ul class="nav nav-pills">
                     <li class="nav-item"><a class="nav-link active" 
                     th:href="@{/hoje/inicial}"> <i class="oi oi-clipboard"></i> 
                     <span>Hoje</span>

How can I display these open transactions and commit or cancel them?

There is no open transaction, MySQL will rollback the transaction upon disconnect.
You cannot commit the transaction (IFAIK).

You display threads using

SHOW FULL PROCESSLIST  

See: http://dev.mysql.com/doc/refman/5.1/en/thread-information.html

It will not help you, because you cannot commit a transaction from a broken connection.

What happens when a connection breaks
From the MySQL docs: http://dev.mysql.com/doc/refman/5.0/en/mysql-tips.html

4.5.1.6.3. Disabling mysql Auto-Reconnect

If the mysql client loses its connection to the server while sending a statement, it immediately and automatically tries to reconnect once to the server and send the statement again. However, even if mysql succeeds in reconnecting, your first connection has ended and all your previous session objects and settings are lost: temporary tables, the autocommit mode, and user-defined and session variables. Also, any current transaction rolls back.

This behavior may be dangerous for you, as in the following example where the server was shut down and restarted between the first and second statements without you knowing it:

Also see: http://dev.mysql.com/doc/refman/5.0/en/auto-reconnect.html

How to diagnose and fix this
To check for auto-reconnection:

If an automatic reconnection does occur (for example, as a result of calling mysql_ping()), there is no explicit indication of it. To check for reconnection, call mysql_thread_id() to get the original connection identifier before calling mysql_ping(), then call mysql_thread_id() again to see whether the identifier has changed.

Make sure you keep your last query (transaction) in the client so that you can resubmit it if need be.
And disable auto-reconnect mode, because that is dangerous, implement your own reconnect instead, so that you know when a drop occurs and you can resubmit that query.

Updated mysqli version:

if ($result = $mysqli->query("SHOW TABLES LIKE '".$table."'")) {
    if($result->num_rows == 1) {
        echo "Table exists";
    }
}
else {
    echo "Table does not exist";
}

Original mysql version:

if(mysql_num_rows(mysql_query("SHOW TABLES LIKE '".$table."'"))==1) 
    echo "Table exists";
else echo "Table does not exist";

Referenced from the PHP docs.

Calling the built-in function stat($fh) returns an array with the following information about the file handle passed in (from the perlfunc man page for stat):

  0 dev      device number of filesystem
  1 ino      inode number
  2 mode     file mode  (type and permissions)
  3 nlink    number of (hard) links to the file
  4 uid      numeric user ID of file's owner
  5 gid      numeric group ID of file's owner
  6 rdev     the device identifier (special files only)
  7 size     total size of file, in bytes
  8 atime    last access time since the epoch
  9 mtime    last modify time since the epoch
 10 ctime    inode change time (NOT creation time!) since the epoch
 11 blksize  preferred block size for file system I/O
 12 blocks   actual number of blocks allocated

Element number 9 in this array will give you the last modified time since the epoch (00:00 January 1, 1970 GMT). From that you can determine the local time:

my $epoch_timestamp = (stat($fh))[9];
my $timestamp       = localtime($epoch_timestamp);

Alternatively, you can use the built-in module File::stat (included as of Perl 5.004) for a more object-oriented interface.

And to avoid the magic number 9 needed in the previous example, additionally use Time::localtime, another built-in module (also included as of Perl 5.004). Together these lead to some (arguably) more legible code:

use File::stat;
use Time::localtime;
my $timestamp = ctime(stat($fh)->mtime);

They're simply different schemes for representing Unicode characters.

Both are variable-length - UTF-16 uses 2 bytes for all characters in the basic multilingual plane (BMP) which contains most characters in common use.

UTF-8 uses between 1 and 3 bytes for characters in the BMP, up to 4 for characters in the current Unicode range of U+0000 to U+1FFFFF, and is extensible up to U+7FFFFFFF if that ever becomes necessary... but notably all ASCII characters are represented in a single byte each.

For the purposes of a message digest it won't matter which of these you pick, so long as everyone who tries to recreate the digest uses the same option.

See this page for more about UTF-8 and Unicode.

(Note that all Java characters are UTF-16 code points within the BMP; to represent characters above U+FFFF you need to use surrogate pairs in Java.)

You can do trickery by using exec() to invoke something that can do HTTP requests, like wget, but you must direct all output from the program to somewhere, like a file or /dev/null, otherwise the PHP process will wait for that output.

If you want to separate the process from the apache thread entirely, try something like (I'm not sure about this, but I hope you get the idea):

exec('bash -c "wget -O (url goes here) > /dev/null 2>&1 &"');

It's not a nice business, and you'll probably want something like a cron job invoking a heartbeat script which polls an actual database event queue to do real asynchronous events.

You can use the iterator that is returned by the begin() method of the map template:

std::map<K,V> myMap;
std::pair<K,V> firstEntry = *myMap.begin()

But remember that the std::map container stores its content in an ordered way. So the first entry is not always the first entry that has been added.

The notion of security is meaningless unless you define what it is that you want to be secure against.

If you want to be secure against stored browser history, some types of logging, and people looking at your URLs, then POST is more secure.

If you want to be secure against somebody sniffing your network activity, then there's no difference.

For those, who faced

stat: unrecognized option: format

when executed the line from Heppo's answer (find $1 -type f -exec stat --format '%Y :%y %n' "{}" \; | sort -nr | cut -d: -f2- | head)

Please try the -c key to replace --format and finally the call will be:

find $1 -type f -exec stat -c '%Y :%y %n' "{}" \; | sort -nr | cut -d: -f2- | head

That worked for me inside of some Docker containers, where stat was not able to use --format option.

It is safe to store your token in localStorage as long as you encrypt it. Below is a compressed code snippet showing one of many ways you can do it.

    import SimpleCrypto from 'simple-crypto-js';

    const saveToken = (token = '') => {
          const encryptInit = new SimpleCrypto('PRIVATE_KEY_STORED_IN_ENV_FILE');
          const encryptedToken = encryptInit.encrypt(token);

          localStorage.setItem('token', encryptedToken);
     }

Then, before using your token decrypt it using PRIVATE_KEY_STORED_IN_ENV_FILE

It is better to create new environment with new name ($newenv):conda create -n $newenv tensorflow

Then by using anaconda navigator under environment tab you can find newenv in the middle column.

By clicking on the play button open terminal and type: activate tensorflow

Then install tensorflow inside the newenv by typing: pip install tensorflow

Now you have tensorflow inside the new environment so then install jupyter by typing: pip install jupyter notebook

Then just simply type: jupyter notebook to run the jupyter notebook.

Inside of the jupyter notebook type: import tensorflow as tf

To test the the tf you can use THIS LINK

I assume you stop execution if something goes wrong.

Jerryf's answer is fine, except for one flaw.

The onload event should be set before the src. Sometimes the src can be loaded instantly and never fire the onload event.

(Like Totty.js pointed out.)

var canvas = document.getElementById("c");
var ctx = canvas.getContext("2d");

var image = new Image();
image.onload = function() {
    ctx.drawImage(image, 0, 0);
};
image.src = "data:image/  png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAIAAAACDbGyAAAAAXNSR0IArs4c6QAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9oMCRUiMrIBQVkAAAAZdEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIEdJTVBXgQ4XAAAADElEQVQI12NgoC4AAABQAAEiE+h1AAAAAElFTkSuQmCC";

raise ValueError('could not find %c in %s' % (ch,str))

If you only need to share data between views/scopes/controllers, the easiest way is to store it in $rootScope. However, if you need a shared function, it is better to define a service to do that.

Something like this..

 RelativeLayout linearLayout = (RelativeLayout) findViewById(R.id.widget43);
                // ListView listView = (ListView) findViewById(R.id.ListView01);

                LayoutInflater inflater = (LayoutInflater) this
                        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                // View footer = inflater.inflate(R.layout.footer, null);
                View footer = LayoutInflater.from(this).inflate(R.layout.footer,
                        null);
                final RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
                        RelativeLayout.LayoutParams.FILL_PARENT,
                        RelativeLayout.LayoutParams.FILL_PARENT);
                layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, 1);
footer.setLayoutParams(layoutParams);

Also, it's probably useful to note that if you have a multiple dimensional Array, you can get the respective dimension just by appending a '[0]' to the array you are querying until you arrive at the appropriate axis/tuple/dimension.

This is probably better explained with the following code:

public class Test {
    public static void main(String[] args){
        String[][] moo = new String[5][12];

        System.out.println(moo.length); //Prints the size of the First Dimension in the array
        System.out.println(moo[0].length);//Prints the size of the Second Dimension in the array
    }

}

Which produces the output:

5
12

function hasSpaces(str) {
  if (str.indexOf(' ') !== -1) {
    return true
  } else {
    return false
  }
}

I don't see an obvious problem with the above.

It's possible your ldap.conf is being overridden, but the command-line options will take precedence, ldapsearch will ignore BINDDN in the main ldap.conf, so the only parameter that could be wrong is the URI. (The order is ETCDIR/ldap.conf then ~/ldaprc or ~/.ldaprc and then ldaprc in the current directory, though there environment variables which can influence this too, see man ldapconf.)

Try an explicit URI:

ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base -H ldap://localhost

or prevent defaults with:

LDAPNOINIT=1 ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

If that doesn't work, then some troubleshooting (you'll probably need the full path to the slapd binary for these):

• make sure your slapd.conf is being used and is correct (as root)

  slapd -T test -f slapd.conf -d 65535

  You may have a left-over or default slapd.d configuration directory which takes preference over your slapd.conf (unless you specify your config explicitly with -f, slapd.conf is officially deprecated in OpenLDAP-2.4). If you don't get several pages of output then your binaries were built without debug support.

• stop OpenLDAP, then manually start slapd in a separate terminal/console with debug enabled (as root, ^C to quit)

  slapd -h ldap://localhost -d 481

  then retry the search and see if you can spot the problem (there will be a lot of schema noise in the start of the output unfortunately). (Note: running slapd without the -u/-g options can change file ownerships which can cause problems, you should usually use those options, probably -u ldap -g ldap )

• if debug is enabled, then try also

  ldapsearch -v -d 63 -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

@Corey - It just simply strips out all invalid characters. However, your comment made me think of the answer.

The problem was that many of the fields in my database are nullable. When using SqlBulkCopy, an empty string is not inserted as a null value. So in the case of my fields that are not varchar (bit, int, decimal, datetime, etc) it was trying to insert an empty string, which obviously is not valid for that data type.

The solution was to modify my loop where I validate the values to this (repeated for each datatype that is not string)

//--- convert decimal values
foreach (DataColumn DecCol in DecimalColumns)
{
     if(string.IsNullOrEmpty(dr[DecCol].ToString()))
          dr[DecCol] = null; //--- this had to be set to null, not empty
     else
          dr[DecCol] = Helpers.CleanDecimal(dr[DecCol].ToString());
}

After making the adjustments above, everything inserts without issues.

That is the right code. What is probably happening is your form is submitting, and you see the new page (where the element will exist again).

In Python2, input is evaluated, input() is equivalent to eval(raw_input()). When you enter klj, Python tries to evaluate that name and raises an error because that name is not defined.

Use raw_input to get a string from the user in Python2.

Demo 1: klj is not defined:

>>> input()
klj
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1, in <module>
NameError: name 'klj' is not defined

Demo 2: klj is defined:

>>> klj = 'hi'
>>> input()
klj
'hi'

Demo 3: getting a string with raw_input:

>>> raw_input()
klj
'klj'

It is probably not the best thing to do. You need to at least check out your PHP error log for things going wrong ;)

Since nobody mentioned it yet, you can compare arrays with the std::equal algorithm:

int iar1[] = {1,2,3,4,5};
int iar2[] = {1,2,3,4,5};

if (std::equal(std::begin(iar1), std::end(iar1), std::begin(iar2)))
    cout << "Arrays are equal.";
else
    cout << "Arrays are not equal.";

You need to include <algorithm> and <iterator>. If you don't use C++11 yet, you can write:

if (std::equal(iar1, iar1 + sizeof iar1 / sizeof *iar1, iar2))

Here is a function to convert UNICODE (ISO_8859_1) to UTF-8

public static String String_ISO_8859_1To_UTF_8(String strISO_8859_1) {
final StringBuilder stringBuilder = new StringBuilder();
for (int i = 0; i < strISO_8859_1.length(); i++) {
  final char ch = strISO_8859_1.charAt(i);
  if (ch <= 127) 
  {
      stringBuilder.append(ch);
  }
  else 
  {
      stringBuilder.append(String.format("%02x", (int)ch));
  }
}
String s = stringBuilder.toString();
int len = s.length();
byte[] data = new byte[len / 2];
for (int i = 0; i < len; i += 2) {
    data[i / 2] = (byte) ((Character.digit(s.charAt(i), 16) << 4)
                         + Character.digit(s.charAt(i+1), 16));
}
String strUTF_8 =new String(data, StandardCharsets.UTF_8);
return strUTF_8;
}

TEST

String strA_ISO_8859_1_i = new String("??????".getBytes(StandardCharsets.UTF_8), StandardCharsets.ISO_8859_1);

System.out.println("ISO_8859_1 strA est = "+ strA_ISO_8859_1_i + "\n String_ISO_8859_1To_UTF_8 = " + String_ISO_8859_1To_UTF_8(strA_ISO_8859_1_i));

Write this a single line of jQuery Code

Rebase doesn't happen in the background. "rebase in progress" means that you started a rebase, and the rebase got interrupted because of conflict. You have to resume the rebase (git rebase --continue) or abort it (git rebase --abort).

As the error message from git rebase --continue suggests, you asked git to apply a patch that results in an empty patch. Most likely, this means the patch was already applied and you want to drop it using git rebase --skip.

Import by using the import keyword:

import package.myclass;

But since it's the default package and same, you just create a new instance like:

elf ob = new elf(); //Instance of elf class

When the Resolve Conflicts->Content Menu are disabled, one may be on the Pending files list. We need to select the Conflicted files option from the drop down (top)

hope it helps

In PHP 7 you can write it even shorter:

$age = $_GET['age'] ?? 27;

This means that the $age variable will be set to the age parameter if it is provided in the URL, or it will default to 27.

See all new features of PHP 7.

I adopted a SQL 2012 database where I was not a sysadmin but was an administrator on the machine. I used SSMS with "Run as Administrator", added my NT account as a SQL login and set the server role to sysadmin. No problem.

For the Java programming language, there is no difference between the two. Java has two types of comments: traditional comments (/* ... */) and end-of-line comments (// ...). See the Java Language Specification. So, for the Java programming language, both /* ... */ and /** ... */ are instances of traditional comments, and they are both treated exactly the same by the Java compiler, i.e., they are ignored (or more correctly: they are treated as white space).

However, as a Java programmer, you do not only use a Java compiler. You use a an entire tool chain, which includes e.g. the compiler, an IDE, a build system, etc. And some of these tools interpret things differently than the Java compiler. In particular, /** ... */ comments are interpreted by the Javadoc tool, which is included in the Java platform and generates documentation. The Javadoc tool will scan the Java source file and interpret the parts between /** ... */ as documentation.

This is similar to tags like FIXME and TODO: if you include a comment like // TODO: fix this or // FIXME: do that, most IDEs will highlight such comments so that you don't forget about them. But for Java, they are just comments.

if u want to set a bitmap object to image view here is simple two line`

Bitmap bitmap=BitmapFactory.decodeResource(getResources(),R.drawable.sample_drawable_image);

If you want to make sure the border is on the inside of your element, you can use

box-sizing:border-box;

this will place the following border on the inside of the element:

border: 10px solid black;

(similar result you'd get using the additonal parameter inset on box-shadow, but instead this one is for the real border and you can still use your shadow for something else.)

Note to another answer above: as soon as you use any inset on box-shadow of a certain element, you are limited to a maximum of 2 box-shadows on that element and would require a wrapper div for further shadowing.

Both solutions should as well get you rid of the undesired 3D effects. Also note both solutions are stackable (see the example I've added in 2018)

.example-border {_x000D_
  width:100px;_x000D_
  height:100px;_x000D_
  border:40px solid blue;_x000D_
  box-sizing:border-box;_x000D_
  float:left;_x000D_
}_x000D_
_x000D_

<div class="example-combined"></div>

You could use it in conjunction with backticks (``) to execute a command without displaying its output, like this:

: `some_command`

Of course you could just do some_command > /dev/null, but the :-version is somewhat shorter.

That being said I wouldn't recommend actually doing that as it would just confuse people. It just came to mind as a possible use-case.

There's no need, just use fadeToggle() on the element:

$('#testElement').fadeToggle('fast');

Here's a demo.

I know this question it is very old. But I didn't see any simple answer like I used to use.

You just need to add the fas class to the input and put a valid hex in this case &#xf002 for Font-Awesome's glyph as here <input type="text" class="fas" placeholder="&#xf002" />

You can find the unicode of each glyph in the official web here.

This is a simple example you don't need css or javascript.

  padding: 5px;_x000D_

java.lang.Thread.activeCount()

We can use Array.sort method to sort this array.

ES5 solution

var array = ["ab", "abcdefgh", "abcd"];

array.sort(function(a, b){return b.length - a.length});

console.log(JSON.stringify(array, null, '\t'));

For ascending sort order: a.length - b.length

For descending sort order: b.length - a.length

ES6 solution

Attention: not all browsers can understand ES6 code!

In ES6 we can use an arrow function expressions.

let array = ["ab", "abcdefgh", "abcd"];

array.sort((a, b) => b.length - a.length);

console.log(JSON.stringify(array, null, '\t'));

When you are using a custom Toolbar, you can use

toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle(R.string.activity_title);
setSupportActionBar(toolbar);
getSupportActionBar().setLogo(R.drawable.logo);

and in your toolbar layout simply set app:titleMarginStart="16dp"

Note that you have to set the icon as a logo, don't use getSupportActionBar().setIcon(R.drawable.logo) instead use: getSupportActionBar().setLogo(R.drawable.logo)

I generally try to avoid the Convert class (meaning: I don't use it) because I find it very confusing: the code gives too few hints on what exactly happens here since Convert allows a lot of semantically very different conversions to occur with the same code. This makes it hard to control for the programmer what exactly is happening.

My advice, therefore, is never to use this class. It's not really necessary either (except for binary formatting of a number, because the normal ToString method of number classes doesn't offer an appropriate method to do this).

Heres a solution.

Setup a boolean sitiation using blur and focus

//see if our window is active
window.isActive = true;
$(window).focus(function() { this.isActive = true; });
$(window).blur(function() { this.isActive = false; });

Bind your link with a jquery click handler that calls something like this.

function startMyApp(){
  document.location = 'fb://';

  setTimeout( function(){
    if (window.isActive) {
        document.location = 'http://facebook.com';
    }
  }, 1000);
}

if the app opens, we'll lose focus on the window and the timer ends. otherwise we get nothing and we load the usual facebook url.

You can save effort with the new AsyncEnumerator NuGet Package, which didn't exist 4 years ago when the question was originally posted. It allows you to control the degree of parallelism:

using System.Collections.Async;
...

await ids.ParallelForEachAsync(async i =>
{
    ICustomerRepo repo = new CustomerRepo();
    var cust = await repo.GetCustomer(i);
    customers.Add(cust);
},
maxDegreeOfParallelism: 10);

Disclaimer: I'm the author of the AsyncEnumerator library, which is open source and licensed under MIT, and I'm posting this message just to help the community.

On most POSIX systems, it is ignored. But, check your system to be sure.

The mode string can also include the letter 'b' either as last character or as a character between the characters in any of the two-character strings described above. This is strictly for compatibility with ISO/IEC 9899:1990 ('ISO C90') and has no effect; the 'b' is ignored.

Linux

The mode string can also include the letter 'b' either as a last character or as a character between the characters in any of the two- character strings described above. This is strictly for compatibility with C89 and has no effect; the 'b' is ignored on all POSIX conforming systems, including Linux. (Other systems may treat text files and binary files differently, and adding the 'b' may be a good idea if you do I/O to a binary file and expect that your program may be ported to non-UNIX environments.)

The best way to find out the REAL type of an object (including BOTH the native Object or DataType name (such as String, Date, Number, ..etc) AND the REAL type of an object (even custom ones); is by grabbing the name property of the object prototype's constructor:

Native Type Ex1:

var string1 = "Test";
console.log(string1.__proto__.constructor.name);

displays:

String

Ex2:

var array1 = [];
console.log(array1.__proto__.constructor.name);

displays:

Array

Custom Classes:

function CustomClass(){_x000D_
  console.log("Custom Class Object Created!");_x000D_
}_x000D_
var custom1 = new CustomClass();_x000D_
_x000D_
console.log(custom1.__proto__.constructor.name);

displays:

It means somewhere in your chain of calls, you tried to access a Property or call a method on an object that was null.

Given your statement:

img1.ImageUrl = ConfigurationManager
                    .AppSettings
                    .Get("Url")
                    .Replace("###", randomString) 
                + Server.UrlEncode(
                      ((System.Web.UI.MobileControls.Form)Page
                      .FindControl("mobileForm"))
                      .Title);

I'm guessing either the call to AppSettings.Get("Url") is returning null because the value isn't found or the call to Page.FindControl("mobileForm") is returning null because the control isn't found.

You could easily break this out into multiple statements to solve the problem:

var configUrl = ConfigurationManager.AppSettings.Get("Url");
var mobileFormControl = Page.FindControl("mobileForm")
                            as System.Web.UI.MobileControls.Form;

if(configUrl != null && mobileFormControl != null)
{
    img1.ImageUrl = configUrl.Replace("###", randomString) + mobileControl.Title;
}

use cut

$ cut -f4-13 file

or if you insist on awk and $13 is the last field

$ awk '{$1=$2=$3="";print}' file

else

$ awk '{for(i=4;i<=13;i++)printf "%s ",$i;printf "\n"}' file

Also u can consider this

$('#select_2').find('option:selected').text();

which might be a little faster solution though I am not sure.

Use a SQL DATA READER:

In this example i use a List instead an array.

try
{
    SqlCommand comm = new SqlCommand("SELECT CategoryID, CategoryName FROM Categories;",connection);
    connection.Open();

    SqlDataReader reader = comm.ExecuteReader();
    List<string> str = new List<string>();
    int i=0;
    while (reader.Read())
    {
        str.Add( reader.GetValue(i).ToString() );
        i++;
    }
    reader.Close();
}
catch (Exception)
{
    throw;
}
finally
{
    connection.Close();
}

i think this is cool, even tho in general its good form to leave the caller of a method responsible for ensuring its called on the right thread.

if (![[NSThread currentThread] isMainThread]) {
    [self performSelector:_cmd onThread:[NSThread mainThread] withObject:someObject waitUntilDone:NO];
    return;
}

It worked for me this way, it's the best I've found. It is for a max length of 200 characters

editObservations.addTextChangedListener(new TextWatcher() {

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        if (editObservations.getText().length() >= 201){
                String str = editObservations.getText().toString().substring(0, 200);
                editObservations.setText(str);
                editObservations.setSelection(str.length());
        }
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count,
                                          int after) {
    }

    @Override
    public void afterTextChanged(Editable s) {
    }
});

It is often preferable to avoid loops and use vectorized functions. If that is not possible there are two approaches:

1. Preallocate your data.frame. This is not recommended because indexing is slow for data.frames.
2. Use another data structure in the loop and transform into a data.frame afterwards. A list is very useful here.

Example to illustrate the general approach:

mylist <- list() #create an empty list

for (i in 1:5) {
  vec <- numeric(5) #preallocate a numeric vector
  for (j in 1:5) { #fill the vector
    vec[j] <- i^j 
  }
  mylist[[i]] <- vec #put all vectors in the list
}
df <- do.call("rbind",mylist) #combine all vectors into a matrix

In this example it is not necessary to use a list, you could preallocate a matrix. However, if you do not know how many iterations your loop will need, you should use a list.

Finally here is a vectorized alternative to the example loop:

outer(1:5,1:5,function(i,j) i^j)

As you see it's simpler and also more efficient.

• Visit phpmyadmin
• Select your database and click on structure
• In front of your table, you can see Empty, click on it to clear all the entries from the selected table.

Or you can do the same using sql query:

Click on SQL present along side Structure

TRUNCATE tablename; //offers better performance, but used only when all entries need to be cleared
or
DELETE FROM tablename; //returns the number of rows deleted

Refer to DELETE and TRUNCATE for detailed documentaion

You shouldn't use CascadeType.ALL on @ManyToOne since entity state transitions should propagate from parent entities to child ones, not the other way around.

The @ManyToOne side is always the Child association since it maps the underlying Foreign Key column.

Therefore, you should move the CascadeType.ALL from the @ManyToOne association to the @OneToMany side, which should also use the mappedBy attribute since it's the most efficient one-to-many table relationship mapping.

You can use urllib.parse.urljoin:

>>> from urllib.parse import urljoin
>>> urljoin('/media/path/', 'js/foo.js')
'/media/path/js/foo.js'

But beware:

>>> urljoin('/media/path', 'js/foo.js')
'/media/js/foo.js'
>>> urljoin('/media/path', '/js/foo.js')
'/js/foo.js'

The reason you get different results from /js/foo.js and js/foo.js is because the former begins with a slash which signifies that it already begins at the website root.

On Python 2, you have to do

from urlparse import urljoin

It depends what you mean by "it". The iterator knows what index it's reached, yes - in the case of a List<T> or an array. But there's no general index within IEnumerator<T>. Whether it's iterating over an indexed collection or not is up to the implementation. Plenty of collections don't support direct indexing.

(In fact, foreach doesn't always use an iterator at all. If the compile-time type of the collection is an array, the compiler will iterate over it using array[0], array[1] etc. Likewise the collection can have a method called GetEnumerator() which returns a type with the appropriate members, but without any implementation of IEnumerable/IEnumerator in sight.)

Options for maintaining an index:

• Use a for loop
• Use a separate variable

• Use a projection which projects each item to an index/value pair, e.g.

   foreach (var x in list.Select((value, index) => new { value, index }))
   {
       // Use x.value and x.index in here
   }
  

• Use my SmartEnumerable class which is a little bit like the previous option

All but the first of these options will work whether or not the collection is naturally indexed.

You can use String.Join. If you have a List<string> then you can call ToArray first:

List<string> names = new List<string>() { "John", "Anna", "Monica" };
var result = String.Join(", ", names.ToArray());

In .NET 4 you don't need the ToArray anymore, since there is an overload of String.Join that takes an IEnumerable<string>.

Results:

John, Anna, Monica

The first one .clear(); will keep the same list just clear the list.

The second one new ArrayList<Integer>(); creates a new ArrayList in memory.

Suggestion: First one because that's what is is designed to do.

std::string var = "sometext" + somevar + "sometext" + somevar;

This doesn't work because the additions are performed left-to-right and "sometext" (the first one) is just a const char *. It has no operator+ to call. The simplest fix is this:

std::string var = std::string("sometext") + somevar + "sometext" + somevar;

Now, the first parameter in the left-to-right list of + operations is a std::string, which has an operator+(const char *). That operator produces a string, which makes the rest of the chain work.

You can also make all the operations be on var, which is a std::string and so has all the necessary operators:

var = "sometext";
var += somevar;
var += "sometext";
var += somevar;

I think, that in this case using PYTHONPATH is a better thing, mostly because it doesn't introduce (questionable) unneccessary code.

After all, if you think of it, your user doesn't need that sys.path thing, because your package will get installed into site-packages, because you will be using a packaging system.

If the user chooses to run from a "local copy", as you call it, then I've observed, that the usual practice is to state, that the package needs to be added to PYTHONPATH manually, if used outside the site-packages.

User order by with that field, and then do distinct.

ProductOrder.objects.order_by('category').values_list('category', flat=True).distinct()

• START MYSQL using admin user
  • mysql -u admin-user -p (ENTER PASSWORD ON PROMPT)
• Create a new user:
  • CREATE USER 'newuser'@'%' IDENTIFIED BY 'password'; (% -> anyhost)
• Grant Privileges:
  • GRANT SELECT,DELETE,INSERT,UPDATE ON db_name.* TO 'newuser'@'%';
  • FLUSH PRIVILEGES;

If you are running EC2 instance don't forget to add the inbound rules in security group with MYSQL/Aurura.

sed -i '/pattern/d' file

Use 'd' to delete a line. This works at least with GNU-Sed.

If your Sed doesn't have the option, to change a file in place, maybe you can use an intermediate file, to store the modification:

sed '/pattern/d' file > tmpfile && mv tmpfile file

Writing directly to the source usually doesn't work: sed '/pattern/d' file > file so make a copy before trying out, if you doubt it.

I wrote a Tester class which can test the performance:

public class Tester
{
    public static void main(String[] args)
    {
        String text = "";

        int loopCount = 10000000;
        long startTime, endTime, duration1, duration2;

        startTime = System.nanoTime();
        for (int i = 0; i < loopCount; i++) {
            text.equals("");
        }
        endTime = System.nanoTime();
        duration1 = endTime - startTime;
        System.out.println(".equals(\"\") duration " +": \t" + duration1);

        startTime = System.nanoTime();
        for (int i = 0; i < loopCount; i++) {
            text.isEmpty();
        }
        endTime = System.nanoTime();
        duration2 = endTime - startTime;
        System.out.println(".isEmpty() duration "+": \t\t" + duration2);

        System.out.println("isEmpty() to equals(\"\") ratio: " + ((float)duration2 / (float)duration1));
    }
}

I found that using .isEmpty() took around half the time of .equals("").

For file operations, Python uses the operating system's default buffering unless you configure it do otherwise. You can specify a buffer size, unbuffered, or line buffered.

For example, the open function takes a buffer size argument.

http://docs.python.org/library/functions.html#open

"The optional buffering argument specifies the file’s desired buffer size:"

• 0 means unbuffered,
• 1 means line buffered,
• any other positive value means use a buffer of (approximately) that size.
• A negative buffering means to use the system default, which is usually line buffered for tty devices and fully buffered for other files.
• If omitted, the system default is used.

code:

bufsize = 0
f = open('file.txt', 'w', buffering=bufsize)

Have you got the driver installed? If you go into Start > Settings > Control Panel > Administrative Tools and click the Data Sources, then select the Drivers tab your driver info should be registered there.

Failing that it may be easier to simply set up a DSN connection to test with.

You can define multiple connection strings of course and set-up a 'mode' for working on different machines.

Also there's ConnectionStrings.com.

-- EDIT --

Just to further this, I found this thread on another site.

System.out.println(char1+""+char2+char3)

or

String s = char1+""+char2+char3;

Note: For those dealing with CJK text (Chinese, Japanese, and Korean), the double-byte space (Unicode \u3000) is not included in \s for any implementation I've tried so far (Perl, .NET, PCRE, Python). You'll need to either normalize your strings first (such as by replacing all \u3000 with \u0020), or you'll have to use a character set that includes this codepoint in addition to whatever other whitespace you're targeting, such as [ \t\u3000].

If you're using Perl or PCRE, you have the option of using the \h shorthand for horizontal whitespace, which appears to include the single-byte space, double-byte space, and tab, among others. See the Match whitespace but not newlines (Perl) thread for more detail.

However, this \h shorthand has not been implemented for .NET and C#, as best I've been able to tell.

Here is your solution for the problem,

$letter = array();
for ($i = 'A'; $i !== 'ZZ'; $i++){
        if(ord($i) % 2 != 0)
           $letter[] .= $i;
}
print_r($letter);

You need to get the ASCII value for that character which will solve your problem.

Here is ord doc and working code.

For your requirement, you can do like this,

for ($i = 'A'; $i !== 'ZZ'; ord($i)+$x){
  $letter[] .= $i;
}
print_r($letter);

Here set $x as per your requirement.

According to the docs for func (*Client) Do:

"An error is returned if caused by client policy (such as CheckRedirect), or if there was an HTTP protocol error. A non-2xx response doesn't cause an error.

When err is nil, resp always contains a non-nil resp.Body."

Then looking at this code:

res, err := client.Do(req)
defer res.Body.Close()

if err != nil {
    return nil, err
}

I'm guessing that err is not nil. You're accessing the .Close() method on res.Body before you check for the err.

The defer only defers the function call. The field and method are accessed immediately.

So instead, try checking the error immediately.

res, err := client.Do(req)

if err != nil {
    return nil, err
}
defer res.Body.Close()

You can use values_list alongside filter like so;

active_emps_first_name = Employees.objects.filter(active=True).values_list('first_name',flat=True)

As I replied to "Is there a simple, consistent way to change the color scheme of Eclipse editors?":

I've been looking for this too and after a bit of research found a workable solution. This is based on the FDT editor for Eclipse, but I'm sure you could apply the same logic to other editors.

My blog post: Howto create a color-scheme for FDT

Hope this helps!

For a more definitive answer, you'll need to post some of your markup. You can simplify your jQuery quite a bit, like the following:

$("#productList li").each(function() {
    var product = $(this);
    var productid = $(".productId", product).val();
    var productPrice = $(".productPrice", product).val();
    var productMSRP = $(".productMSRP", product).val();

    // the rest remains unchanged
}

In addition to Ishan's answer, if you want to draw programatically without user interaction, you can edit the class just a little like this.

public class DrawingCanvas extends View {

private Paint mPaint;
private Path mPath;
private boolean isUserInteractionEnabled = false;

public DrawingCanvas(Context context, AttributeSet attrs) {
    super(context, attrs);
    mPaint = new Paint();
    mPaint.setColor(Color.RED);
    mPaint.setStyle(Paint.Style.STROKE);
    mPaint.setStrokeJoin(Paint.Join.ROUND);
    mPaint.setStrokeCap(Paint.Cap.ROUND);
    mPaint.setStrokeWidth(10);
    mPath = new Path();
}


@Override
protected void onDraw(Canvas canvas) {
    canvas.drawPath(mPath, mPaint);
    super.onDraw(canvas);
}


@Override
public boolean onTouchEvent(MotionEvent event) {
    if (isUserInteractionEnabled) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                mPath.moveTo(event.getX(), event.getY());
                break;
            case MotionEvent.ACTION_MOVE:
                mPath.lineTo(event.getX(), event.getY());
                invalidate();
                break;
            case MotionEvent.ACTION_UP:
                break;
        }
    }

    return true;
}

public void moveCursorTo(float x, float y) {
    mPath.moveTo(x, y);
}

public void makeLine(float toX, float toY) {
    mPath.lineTo(toX, toY);
}

public void setUserInteractionEnabled(boolean userInteractionEnabled) {
    isUserInteractionEnabled = userInteractionEnabled;
}
}

And then use it like

drawingCanvas.setUserInteractionEnabled(true) // to enable user interaction
drawingCanvas.setUserInteractionEnabled(true) // to disable user interaction

To Draw programatically

drawingCanvas.moveCursorTo(70f, 70f) // Move the cursor (Define starting point)
drawingCanvas.makeLine(200f, 200f) // End point (To where you need to draw)

Inside testing2.php you should print the $_POST array which contains all the data from the post. Also, $_POST['name'] should be available. For more info check $_POST on php.net.

This may be helpful :

SecureRandom.base64(15).tr('+/=', '0aZ')

If you want to remove any special character than put in first argument '+/=' and any character put in second argument '0aZ' and 15 is the length here .

And if you want to remove the extra spaces and new line character than add the things like :

SecureRandom.base64(15).tr('+/=', '0aZ').strip.delete("\n")

Hope this will help to anybody.

API 29.+ usage AndroidX libraries. If you are using API 29.+, then you cannot remove these. If you want to remove AndroidX, then you need to remove the entire 29.+ API from your SDK:

This will work fine.

You can use c++ boost::property_tree::ptree for parsing json data. here is the example for your json data. this would be more easy if you shift name inside each child nodes

#include <iostream>

    people.push_back(std::make_tuple("Anna", age, profession));                 

    //Get Second child

You'll need to use fs for that: http://nodejs.org/api/fs.html

And in particular the fs.rename() function:

var fs = require('fs');
fs.rename('/path/to/Afghanistan.png', '/path/to/AF.png', function(err) {
    if ( err ) console.log('ERROR: ' + err);
});

Put that in a loop over your freshly-read JSON object's keys and values, and you've got a batch renaming script.

fs.readFile('/path/to/countries.json', function(error, data) {
    if (error) {
        console.log(error);
        return;
    }

    var obj = JSON.parse(data);
    for(var p in obj) {
        fs.rename('/path/to/' + obj[p] + '.png', '/path/to/' + p + '.png', function(err) {
            if ( err ) console.log('ERROR: ' + err);
        });
    }
});

(This assumes here that your .json file is trustworthy and that it's safe to use its keys and values directly in filenames. If that's not the case, be sure to escape those properly!)

If you know the width of the child element you are animating, you can use and animate a margin offset as well. For example, this will animate from left:0 to right:0

CSS:

.parent{
width:100%;
position:relative;
}

#itemToMove{
position:absolute;
width:150px;
right:100%;
margin-right:-150px;
}

Javascript:

$( "#itemToMove" ).animate({
"margin-right": "0",
"right": "0"
}, 1000 );

From a sqlite prompt:

sqlite> .read db.sql

Or:

cat db.sql | sqlite3 database.db

Also, your SQL is invalid - you need ; on the end of your statements:

create table server(name varchar(50),ipaddress varchar(15),id init);
create table client(name varchar(50),ipaddress varchar(15),id init);

You can use a data: URL to embed a Base64 encoded version of an image. But it's not very efficient and wouldn't recommend embedding large images. Any reason linking to another file is not feasible?

var list = arr.Select(i => Int32.Parse(i));

Using domain Name may solve the problem (get domain name using powershell: $env:userdomain):

    Hashtable<String, Object> env = new Hashtable<String, Object>();
    String principalName = "domainName\\userName";
    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, "ldap://URL:389/OU=ou-xx,DC=fr,DC=XXXXXX,DC=com");
    env.put(Context.SECURITY_AUTHENTICATION, "simple");
    env.put(Context.SECURITY_PRINCIPAL, principalName);
    env.put(Context.SECURITY_CREDENTIALS, "Your Password");

    try {
        DirContext authContext = new InitialDirContext(env);
        // user is authenticated
        System.out.println("USER IS AUTHETICATED");
    } catch (AuthenticationException ex) {
        // Authentication failed
        System.out.println("AUTH FAILED : " + ex);

    } catch (NamingException ex) {
        ex.printStackTrace();
    }

Here is solution:

<?php

$students['ter1003']['birthplace'] = ("San Juan <br>");
$students['fgg1003']['birthplace'] = ("Quezon City <br>");
$students['bdf1003']['birthplace'] = ("Manila <br>");

$key = array_search('Delata Jona', array_column($students, 'name'));
echo $key;  

?>

You can define two entry points in your webpack configuration, one for your normal js and the other one for minified js. Then you should output your bundle with its name, and configure UglifyJS plugin to include min.js files. See the example webpack configuration for more details:

module.exports = {
 entry: {
   'bundle': './src/index.js',
   'bundle.min': './src/index.js',
 },

 output: {
   path: path.resolve(__dirname, 'dist'),
   filename: "[name].js"
 },

 plugins: [
   new webpack.optimize.UglifyJsPlugin({
      include: /\.min\.js$/,
      minimize: true
   })
 ]
};

After running webpack, you will get bundle.js and bundle.min.js in your dist folder, no need for extra plugin.

In PostgreSQL, to get the average of multiple (2 to 8) columns in one row just define a set of seven functions called average(). Will produce the average of the non-null columns.

And then just

select *,(r1+r2+r3+r4+r5)/5.0,average(r1,r2,r3,r4,r5) from request;
 req_id | r1 | r2 | r3 | r4 | r5 |      ?column?      |      average

I never remember the openssl command needed to create a .pem file, so I made this bash script to simplify the process:

#!/bin/bash
if [ $# -eq 2 ]
then
    echo "Signing $1..."

    if ! openssl pkcs12 -in $1 -out $2 -nodes -clcerts; then
        echo "Error signing certificate."
    else
        echo "Certificate created successfully: $2"
    fi
else
    if [ $# -gt 2 ]
    then
        echo "Too many arguments"
        echo "Syntax: $0 <input.p12> <output.pem>"
    else
        echo "Missing arguments"
        echo "Syntax: $0 <input.p12> <output.pem>"
    fi
fi

Name it, for example, signpem.sh and save it on your user's folder (/Users/<username>?). After creating the file, do a chmod +x signpem.sh to make it executable and then you can run:

~/signpem myCertificate.p12 myCertificate.pem

And myCertificate.pem will be created.

you can add keyup event like this

template: `
  <input (keyup)="onKey($event)">
  <p>{{values}}</p>
`

in Component, code some like below

export class KeyUpComponent_v1 {
  values = '';

  onKey(event:any) { // without type info
    this.values += event.target.value + ' | ';
  }
}

If you're okay with Apache commons lib

outputWriter.write(ArrayUtils.join(array, ","));

A solution is to create your own jquery plugin that take the json map and populate the select with it.

(function($) {     
     $.fn.fillValues = function(options) {
         var settings = $.extend({
             datas : null, 
             complete : null,
         }, options);

         this.each( function(){
            var datas = settings.datas;
            if(datas !=null) {
                $(this).empty();
                for(var key in datas){
                    $(this).append('<option value="'+key+'"+>'+datas[key]+'</option>');
                }
            }
            if($.isFunction(settings.complete)){
                settings.complete.call(this);
            }
        });

    }

}(jQuery));

You can call it by doing this :

$("#select").fillValues({datas:your_map,});

The advantages is that anywhere you will face the same problem you just call

 $("....").fillValues({datas:your_map,});

Et voila !

You can add functions in your plugin as you like

I'm not sure I understand your question. But there are two approaches to making the image invisible...

Pure HTML

<img src="a.gif" style="display: none;" />

Or...

HTML + Javascript

<script type="text/javascript">
document.getElementById("myImage").style.display = "none";
</script>

<img id="myImage" src="a.gif" />

I had the same issue with cmake-gui (No CMAKE_CXX_COMPILER could be found.), while running CMake from the command line worked fine. After manually adding the entries

to the PATH environment variable it worked for me.

tl;dr

myJavaUtilDate.toInstant()
              .plusHours( 8 )

Or…

myJavaUtilDate.toInstant()                // Convert from legacy class to modern class, an `Instant`, a point on the timeline in UTC with resolution of nanoseconds.
              .plus(                      // Do the math, adding a span of time to our moment, our `Instant`. 
                  Duration.ofHours( 8 )   // Specify a span of time unattached to the timeline.
               )                          // Returns another `Instant`. Using immutable objects creates a new instance while leaving the original intact.

Using java.time

The java.time framework built into Java 8 and later supplants the old Java.util.Date/.Calendar classes. Those old classes are notoriously troublesome. Avoid them.

Use the toInstant method newly added to java.util.Date to convert from the old type to the new java.time type. An Instant is a moment on the time line in UTC with a resolution of nanoseconds.

Instant instant = myUtilDate.toInstant();

You can add hours to that Instant by passing a TemporalAmount such as Duration.

Duration duration = Duration.ofHours( 8 );
Instant instantHourLater = instant.plus( duration );

To read that date-time, generate a String in standard ISO 8601 format by calling toString.

String output = instantHourLater.toString();

You may want to see that moment through the lens of some region’s wall-clock time. Adjust the Instant into your desired/expected time zone by creating a ZonedDateTime.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

Alternatively, you can call plusHours to add your count of hours. Being zoned means Daylight Saving Time (DST) and other anomalies will be handled on your behalf.

ZonedDateTime later = zdt.plusHours( 8 );

You should avoid using the old date-time classes including java.util.Date and .Calendar. But if you truly need a java.util.Date for interoperability with classes not yet updated for java.time types, convert from ZonedDateTime via Instant. New methods added to the old classes facilitate conversion to/from java.time types.

java.util.Date date = java.util.Date.from( later.toInstant() );

For more discussion on converting, see my Answer to the Question, Convert java.util.Date to what “java.time” type?.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

First of all, the annotation doesn't annotate List. It annotates the method, just as RequestMapping does. Your code is equivalent to

@RequestMapping(value="/orders", method=RequestMethod.GET)
@ResponseBody
public List<Account> accountSummary() {
    return accountManager.getAllAccounts();
}

Now what the annotation means is that the returned value of the method will constitute the body of the HTTP response. Of course, an HTTP response can't contain Java objects. So this list of accounts is transformed to a format suitable for REST applications, typically JSON or XML.

The choice of the format depends on the installed message converters, on the values of the produces attribute of the @RequestMapping annotation, and on the content type that the client accepts (that is available in the HTTP request headers). For example, if the request says it accepts XML, but not JSON, and there is a message converter installed that can transform the list to XML, then XML will be returned.

I have done with below single git command:

git clone [url] -b [branch-name] --single-branch

For internal gridlines, use the tag: td For external gridlines, use the tag: table

Here is a complete example

#include <thread>
#include <iostream>

class Wrapper {
   public:
      void member1() {
          std::cout << "i am member1" << std::endl;
      }
      void member2(const char *arg1, unsigned arg2) {
          std::cout << "i am member2 and my first arg is (" << arg1 << ") and second arg is (" << arg2 << ")" << std::endl;
      }
      std::thread member1Thread() {
          return std::thread([=] { member1(); });
      }
      std::thread member2Thread(const char *arg1, unsigned arg2) {
          return std::thread([=] { member2(arg1, arg2); });
      }
};
int main(int argc, char **argv) {
   Wrapper *w = new Wrapper();
   std::thread tw1 = w->member1Thread();
   std::thread tw2 = w->member2Thread("hello", 100);
   tw1.join();
   tw2.join();
   return 0;
}

Compiling with g++ produces the following result

g++ -Wall -std=c++11 hello.cc -o hello -pthread

i am member1
i am member2 and my first arg is (hello) and second arg is (100)

I've just solved a problem related to this which may help other people.

Initially when loading up MSSMSE it had the server as PC_NAME\SQLEXPRESS and when I tried to connect it gave me Error: 26 - Error Locating Server/Instance Specified, so I went into SQL Server Configuration Manager to check if my SQL Server Browser and SQL Server services were running and set to automatic, only to find that instead of saying SQL Server (SQLEXPRESS) it says SQL Server(MSSQLSERVER).

I then tried connecting to PC-NAME\MSSQLSERVER and this time got SQL Network Interfaces, error: 25 - Connection string is not valid) (MicrosoftSQL Server, Error: 87) The parameter is incorrect so I googled this error and found that somebody had suggested that instead of using PC-NAME\MSSQLSERVER just use PC-NAME as the Server Name at the server connection interface, and this seems to work.

There's a link here http://learningsqlserver.wordpress.com/2011/01/21/what-version-of-sql-server-do-i-have/ which explains that MSSQLSERVER is the default instance and can be connected to by using just your hostname.

I think this may have arisen because I've had SQL Server 2008 installed at some point in the past.

In modern browsers that support HTML5, the following is possible:

<a href="link/to/your/download/file" download>Download link</a>

You also can use this:

<a href="link/to/your/download/file" download="filename">Download link</a>

This will allow you to change the name of the file actually being downloaded.

You can define foreign key by:

public class Parent
{
   public int Id { get; set; }
   public virtual ICollection<Child> Childs { get; set; }
}

public class Child
{
   public int Id { get; set; }
   // This will be recognized as FK by NavigationPropertyNameForeignKeyDiscoveryConvention
   public int ParentId { get; set; } 
   public virtual Parent Parent { get; set; }
}

Now ParentId is foreign key property and defines required relation between child and existing parent. Saving the child without exsiting parent will throw exception.

If your FK property name doesn't consists of the navigation property name and parent PK name you must either use ForeignKeyAttribute data annotation or fluent API to map the relation

Data annotation:

// The name of related navigation property
[ForeignKey("Parent")]
public int ParentId { get; set; }

Fluent API:

modelBuilder.Entity<Child>()
            .HasRequired(c => c.Parent)
            .WithMany(p => p.Childs)
            .HasForeignKey(c => c.ParentId);

Other types of constraints can be enforced by data annotations and model validation.

Edit:

You will get an exception if you don't set ParentId. It is required property (not nullable). If you just don't set it it will most probably try to send default value to the database. Default value is 0 so if you don't have customer with Id = 0 you will get an exception.

The value for an annotation must be a compile time constant, so there is no simple way of doing what you are trying to do.

See also here: How to supply value to an annotation from a Constant java

It is possible to use some compile time tools (ant, maven?) to config it if the value is known before you try to run the program.

SET

SET @var_name = value 

OR

SET @var := value

both operators = and := are accepted

SELECT

SELECT col1, @var_name := col2 from tb_name WHERE "conditon";

if multiple record sets found only the last value in col2 is keep (override);

SELECT col1, col2 INTO @var_name, col3 FROM .....

in this case the result of select is not containing col2 values

Ex both methods used

-- TRIGGER_BEFORE_INSERT --- setting a column value from calculations

...
SELECT count(*) INTO @NR FROM a_table WHERE a_condition;
SET NEW.ord_col =  IFNULL( @NR, 0 ) + 1;

            if (logOut)
                Login();
        }
        else
            Application.Exit();
    }

    static void main_FormClosed(object sender, FormClosedEventArgs e)
    {
        logOut= (sender as MainForm).logOut;
    }
}

public partial class MainForm : Form
{
    private void btnLogout_ItemClick(object sender, ItemClickEventArgs e)
    {
        //timer1.Stop();
        this.logOut= true;
        this.Close();
    }
}

Normally, Spring should do the autowiring, as long as your abstract class is in the base-package provided for component scan.

See this and this for further reference.

@Service and @Component are both stereotypes that creates beans of the annotated type inside the Spring container. As Spring Docs state,

This annotation serves as a specialization of @Component, allowing for implementation classes to be autodetected through classpath scanning.

Python decorator is like a wrapper of a function or a class. It’s still too conceptual.

def function_decorator(func):
    def wrapped_func():
        # Do something before the function is executed
        func()
        # Do something after the function has been executed
    return wrapped_func

The above code is a definition of a decorator that decorates a function. function_decorator is the name of the decorator.

wrapped_func is the name of the inner function, which is actually only used in this decorator definition. func is the function that is being decorated. In the inner function wrapped_func, we can do whatever before and after the func is called. After the decorator is defined, we simply use it as follows.

@function_decorator
def func():
    pass

Then, whenever we call the function func, the behaviours we’ve defined in the decorator will also be executed.

EXAMPLE :

from functools import wraps

def mydecorator(f):
    @wraps(f)
    def wrapped(*args, **kwargs):
        print "Before decorated function"
        r = f(*args, **kwargs)
        print "After decorated function"
        return r
    return wrapped

@mydecorator
def myfunc(myarg):
    print "my function", myarg
    return "return value"

r = myfunc('asdf')
print r

Output :

    Before decorated function
    my function asdf
    After decorated function
    return value

When I try:

<input type="button" id="moreFields" onclick="alert('The text will be show!!'); return false;" value="Give me more fields!"  />

It's worked well. So I think the problem is position of moreFields() function. Ensure that function will be define before your input tag.

Pls try:

<script type="text/javascript">
    function moreFields() {
        alert("The text will be show");
    }
</script>

<input type="button" id="moreFields" onclick="moreFields()" value="Give me more fields!"  />

Hope it helped.

 this.LabelControl.Text = datatable.AsEnumerable()
    .Sum(x => x.Field<int>("Amount"))
    .ToString();

If you want to filter the results:

 this.LabelControl.Text = datatable.AsEnumerable()
    .Where(y => y.Field<string>("SomeCol") != "foo")
    .Sum(x => x.Field<int>("MyColumn") )
    .ToString();

If you want to update/replace the values of first dataframe df1 with the values of second dataframe df2. you can do it by following steps —

Step 1: Set index of the first dataframe (df1)

df1.set_index('id')

Step 2: Set index of the second dataframe (df2)

df2.set_index('id')

and finally update the dataframe using the following snippet —

df1.update(df2)

In Jelly.core to test a literal string one would use:

<core:when test="${ name == 'ABC' }"> 

But if I have to check for string "Toy's R Us":

<core:when test="${ name == "Toy's R Us" }">

It would be like this, if the double quotes were allowed inside:

<core:when test="${ name == "Toy's R Us" }"> 

You can use the getters of java.time.LocalDateTime for that.

LocalDateTime now = LocalDateTime.now();
int year = now.getYear();
int month = now.getMonthValue();
int day = now.getDayOfMonth();
int hour = now.getHour();
int minute = now.getMinute();
int second = now.getSecond();
int millis = now.get(ChronoField.MILLI_OF_SECOND); // Note: no direct getter available.

System.out.printf("%d-%02d-%02d %02d:%02d:%02d.%03d", year, month, day, hour, minute, second, millis);

Or, when you're not on Java 8 yet, make use of java.util.Calendar.

Calendar now = Calendar.getInstance();
int year = now.get(Calendar.YEAR);
int month = now.get(Calendar.MONTH) + 1; // Note: zero based!
int day = now.get(Calendar.DAY_OF_MONTH);
int hour = now.get(Calendar.HOUR_OF_DAY);
int minute = now.get(Calendar.MINUTE);
int second = now.get(Calendar.SECOND);
int millis = now.get(Calendar.MILLISECOND);

System.out.printf("%d-%02d-%02d %02d:%02d:%02d.%03d", year, month, day, hour, minute, second, millis);

Either way, this prints as of now:

2010-04-16 15:15:17.816

To convert an int to String, make use of String#valueOf().

If your intent is after all to arrange and display them in a human friendly string format, then better use either Java8's java.time.format.DateTimeFormatter (tutorial here),

LocalDateTime now = LocalDateTime.now();
String format1 = now.format(DateTimeFormatter.ISO_DATE_TIME);
String format2 = now.atZone(ZoneId.of("GMT")).format(DateTimeFormatter.RFC_1123_DATE_TIME);
String format3 = now.format(DateTimeFormatter.ofPattern("yyyyMMddHHmmss", Locale.ENGLISH));

System.out.println(format1);
System.out.println(format2);
System.out.println(format3);

or when you're not on Java 8 yet, use java.text.SimpleDateFormat:

Date now = new Date(); // java.util.Date, NOT java.sql.Date or java.sql.Timestamp!
String format1 = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS", Locale.ENGLISH).format(now);
String format2 = new SimpleDateFormat("EEE, d MMM yyyy HH:mm:ss Z", Locale.ENGLISH).format(now);
String format3 = new SimpleDateFormat("yyyyMMddHHmmss", Locale.ENGLISH).format(now);

System.out.println(format1);
System.out.println(format2);
System.out.println(format3);

Either way, this yields:

2010-04-16T15:15:17.816
Fri, 16 Apr 2010 15:15:17 GMT
20100416151517

You can control this via HTTP header by adding Access-Control-Allow-Origin. Setting it to * will accept cross-domain AJAX requests from any domain.

Using PHP it's really simple, just add the following line into the script that you want to have access outside from your domain:

header("Access-Control-Allow-Origin: *");

Don't forget to enable mod_headers module in httpd.conf.

Lazy setting decides whether to load child objects while loading the Parent Object.You need to do this setting respective hibernate mapping file of the parent class.Lazy = true (means not to load child)By default the lazy loading of the child objects is true. This make sure that the child objects are not loaded unless they are explicitly invoked in the application by calling getChild() method on parent.In this case hibernate issues a fresh database call to load the child when getChild() is actully called on the Parent object.But in some cases you do need to load the child objects when parent is loaded. Just make the lazy=false and hibernate will load the child when parent is loaded from the database.Exampleslazy=true (default)Address child of User class can be made lazy if it is not required frequently.lazy=falseBut you may need to load the Author object for Book parent whenever you deal with the book for online bookshop.

In short, you can navigate to MobileDevice/Provisioning Profiles/ folder path and delete all profiles and then Archive. Now you can see there are new profiles for you. Cheers :)

@JasonH hope it will help you.

I've used CSS Grid to fix that. CSS Grid will make all the elements in the same row, all the same height.

I haven't looked into making all the elements in all the rows the same height though.

Anyway, here's how it can be done:

HTML:

<div class="grid-container">

  <div class="card">...</div>
  <div class="card">...</div>
</div>

CSS:

.grid-container {
  display: grid;  
  grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));
}

Here's a complete JSFiddle. https://jsfiddle.net/bluegrounds/owjvhstq/4/

To get the current time in UTC in Python 3.2+:

>>> from datetime import datetime, timezone
>>> datetime.now(timezone.utc).isoformat()
'2015-01-27T05:57:31.399861+00:00'

To get local time in Python 3.3+:

>>> from datetime import datetime, timezone
>>> datetime.now(timezone.utc).astimezone().isoformat()
'2015-01-27T06:59:17.125448+01:00'

Explanation: datetime.now(timezone.utc) produces a timezone aware datetime object in UTC time. astimezone() then changes the timezone of the datetime object, to the system's locale timezone if called with no arguments. Timezone aware datetime objects then produce the correct ISO format automatically.

I found this solution on Mike Hike Hostetler's site that worked perfectly for me.

# rsync -avz -e "ssh -p $portNumber" user@remoteip:/path/to/files/ /local/path/

For all who search to return something and then for another call throw exception:

when(mockFoo.someMethod())
        .thenReturn(obj1)
        .thenReturn(obj2)
        .thenThrow(new RuntimeException("Fail"));

or

when(mockFoo.someMethod())
        .thenReturn(obj1, obj2)
        .thenThrow(new RuntimeException("Fail"));

it's worked for me set tabindex to 0 this.yourtextbox.TabIndex = 0;

So, if you are using flask_restful Package for API's returning 201 would becomes like

def bla(*args, **kwargs):
    ...
    return data, 201

where data should be any hashable/ JsonSerialiable value, like dict, string.

this code helps to get it easily............

Actually in some devices external sdcard default name is showing as extSdCard and for other it is sdcard1. This code snippet helps to find out that exact path and helps to retrive you the path of external device..

String sdpath,sd1path,usbdiskpath,sd0path; 

if(new File("/storage/extSdCard/").exists()) 
{ 
  sdpath="/storage/extSdCard/";
  Log.i("Sd Cardext Path",sdpath); 
} 
if(new File("/storage/sdcard1/").exists()) 
{ 
  sd1path="/storage/sdcard1/";
  Log.i("Sd Card1 Path",sd1path); 
} 
if(new File("/storage/usbcard1/").exists()) 
{ 
  usbdiskpath="/storage/usbcard1/";
  Log.i("USB Path",usbdiskpath); 
} 
if(new File("/storage/sdcard0/").exists()) 
{ 
  sd0path="/storage/sdcard0/";
  Log.i("Sd Card0 Path",sd0path); 
}

Although this is old, it still keeps coming up pretty well in google. So I figured I'd mention this. No one mentioned to check for when x = 0.

0! and 1! both = 1.

This isn't being checked with the previous answers, and would cause a stack overflow, if fact(0) was run. Anyway simple fix:

public static int fact(int x){
    if (x==1 | x==0)
        return 1;
    return fact(x-1) * x;
}// fact

Almost what I wanted @Ralph, but here is the best answer. It'll solve your code problems:

1. it exports just the hardcoded sheet named "Sheet1";
2. it always exports to the same temp file, overwriting it;
3. it ignores the locale separation char.

To solve these problems, and meet all my requirements, I've adapted the code from here. I've cleaned it a little to make it more readable.

Option Explicit
Sub ExportAsCSV()
 
    Dim MyFileName As String
    Dim CurrentWB As Workbook, TempWB As Workbook
     
    Set CurrentWB = ActiveWorkbook
    ActiveWorkbook.ActiveSheet.UsedRange.Copy
 
    Set TempWB = Application.Workbooks.Add(1)
    With TempWB.Sheets(1).Range("A1")
      .PasteSpecial xlPasteValues
      .PasteSpecial xlPasteFormats
    End With        

    Dim Change below to "- 4"  to become compatible with .xls files
    MyFileName = CurrentWB.Path & "\" & Left(CurrentWB.Name, Len(CurrentWB.Name) - 5) & ".csv"
     
    Application.DisplayAlerts = False
    TempWB.SaveAs Filename:=MyFileName, FileFormat:=xlCSV, CreateBackup:=False, Local:=True
    TempWB.Close SaveChanges:=False
    Application.DisplayAlerts = True
End Sub

There are still some small thing with the code above that you should notice:

1. .Close and DisplayAlerts=True should be in a finally clause, but I don't know how to do it in VBA
2. It works just if the current filename has 4 letters, like .xlsm. Wouldn't work in .xls excel old files. For file extensions of 3 chars, you must change the - 5 to - 4 when setting MyFileName.
3. As a collateral effect, your clipboard will be substituted with current sheet contents.

Edit: put Local:=True to save with my locale CSV delimiter.

I have faced the same issue when I tried to install xampp on windows 8.1. The problem in my system was there was no password for the current logged in user account. After creating the password then I tried to install xampp. It installed without any issue. Hope it helps someone in the feature.

Using "VanillaJS" means using plain JavaScript without any additional libraries like jQuery.

People use it as a joke to remind other developers that many things can be done nowadays without the need for additional JavaScript libraries.

Here's a funny site that jokingly talks about this: http://vanilla-js.com/

APC segfaults all day and all night, got no experience with eAccelerator but XCache is very reliable with loads of options and constant development.

If you're using AForge.NET:

using(var croppedBitmap = new Crop(new Rectangle(10, 10, 10, 10)).Apply(bitmap))
{
    // ...
}

Since you mention cls, it sounds like you are referring to windows. If so, then this KB item has the code that will do it. I just tried it, and it worked when I called it with the following code:

cls( GetStdHandle( STD_OUTPUT_HANDLE ));

In addition to Mathias answer.

Although not mentioned in OP, if you also need to see the Powershell specific/related internal variables, you need to use Get-Variable:

$ Get-Variable

Name                           Value
----                           -----

?                              True
^                              gci
args                           {}
ChocolateyTabSettings          @{AllCommands=False}
ConfirmPreference              High
DebugPreference                SilentlyContinue

false                          False
FormatEnumerationLimit         4
...

These also include stuff you may have set in your profile startup script.

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).

The Chosen plugin does not automatically update its list of options when the OPTION elements in the DOM change. You have to send it an event to trigger the update:

Pre Chosen 1.0: $('.chzn-select').trigger("liszt:updated");

Chosen 1.0 $('.chosen-select').trigger("chosen:updated");

If you are dynamically managing the OPTION elements, then you'll have to do this whenever the OPTIONs change. The way you do this will vary - in AngularJS, try something like this:

$scope.$watch(
  function() {
    return element.find('option').map(function() { return this.value }).get().join();
  }, 
  function() {
    element.trigger('liszt:updated');
  }
 }

Try connecting to a vpn, if possible. That was the reason I was facing problem. Tip: if you're using an ec2 machine, try rebooting it. This worked for me the other day :)

If searching for an element is important, I'd recommend std::set instead of std::vector. Using this:

std::find(vec.begin(), vec.end(), x) runs in O(n) time, but std::set has its own find() member (ie. myset.find(x)) which runs in O(log n) time - that's much more efficient with large numbers of elements

std::set also guarantees all the added elements are unique, which saves you from having to do anything like if not contained then push_back()....

API 21 has view.setElevation(float) build-in

Use ViewCompat.setElevation(view, float); for backward compatibility

More methods ViewCompat.setZ(v, pixels) and ViewCompat.setTranslationZ(v, pixels)

Another way collect buttons or view array and use addView to add to RelativeLayout
