That still tells us nothing about what you are trying to do: we have no idea what controls you are trying to use and failing with, let alone how you are trying to use them!
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.

 This has "long day" written all over it ...
What does that have to do with C#?
What controls are you using?
What - exactly - are you trying to do with them?
Please, remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with. Unless you give us information, we can't respond to it - and we have no idea what code you are trying ...

This is one of the most common problems we get asked, and it's also the one we are least equipped to answer, but you are most equipped to answer yourself.
Let me just explain what the error means: You have tried to use a variable, property, or a method return value but it contains null - which means that there is no instance of a class in the variable.
It's a bit like a pocket: you have a pocket in your shirt, which you use to hold a pen. If you reach into the pocket and find there isn't a pen there, you can't sign your name on a piece of paper - and you will get very funny looks if you try! The empty pocket is giving you a null value (no pen here!) so you can't do anything that you would normally do once you retrieved your pen. Why is it empty? That's the question - it may be that you forgot to pick up your pen when you left the house this morning, or possibly you left the pen in the pocket of yesterdays shirt when you took it off last night.
We can't tell, because we weren't there, and even more importantly, we can't even see your shirt, much less what is in the pocket!
Back to computers, and you have done the same thing, somehow - and we can't see your code, much less run it and find out what contains null when it shouldn't.
But you can - and Visual Studio will help you here. Run your program in the debugger and when it fails, VS will show you the line it found the problem on. You can then start looking at the various parts of it to see what value is null and start looking back through your code to find out why. So put a breakpoint at the beginning of the method containing the error line, and run your program from the start again. This time, VS will stop before the error, and let you examine what is going on by stepping through the code looking at your values.
But we can't do that - we don't have your code, we don't know how to use it if we did have it, we don't have your data. So try it - and see how much information you can find out!

If you want to add drag & drop from Explorer, then it will work the same for any file; it's up to you whether or not to do something with the event. There's plenty examples of that in the CodeProject articles.

Which Control will Work for Acrobat Pdf in properties there is not DragDrop Event and DragEnter
|
|
|
|
|
If you're looking for a control to automatically handle the Drag and Drop for you AND/OR display a PDF for you without any work on your part, in either case, there is no such thing.

Hi loaded multiple files in web browser
But when I load image , image size is not fitScale in webbrowser . But pdf drag in same webbrowser it fitScale window and preview full screen.
If I use image width and height in webbrowser then image image was fitScale in webbrowser window.
But I can’t load in same webbrowser window pdf

I don't have a clue what you're talking about.
You offer up no context about anything. We have no idea what kind of app you're writing (Windows Forms, WPF, ASP.NET/MVC, ...), what problem you're having, how this "web browser" and "fitScale" stuff figures into your app, ... nothing makes any sense.

That's because a PDF doesn't show in an IMG tag. Look at the page source HTML after the PDF loads.

"Which Control will Work for Acrobat Pdf in properties there is not DragDrop Event and DragEnter"
Not everything is exposed using properties. If you want to drag and drop from Shell/Explorer, then you have to start coding. Also, the type of file is not relevant; it works the same way for all files

Weekend is approaching, and in case you may feel bored without a complicated programming task, I have a puzzle for you.
I already asked at StackOverflow: c# - Logging exceptions in fire&forget tasks - Stack Overflow[^], but did not get a usable answer.
In short, I want to create a method which takes an Action parameter, fires off a Task with it, and makes sure that exceptions do not crash the application (but logs the exception messages so that I can find out that something bad happened).
I tried following code:
public static void CreateAndStartTaskWithErrorLogging(Action _action, string _componentName, string _originalStacktrace = null)
{
DateTime started = HighPrecisionClock.Now;
Task task = new Task(_action);
task.ContinueWith(_continuation => _continuation.LogExceptions(_componentName, started, _originalStacktrace));
task.ConfigureAwait(false);
task.Start();
}
internal static void LogExceptions(this Task _t, string _componentName, DateTime _started, string _originalStacktrace = null)
{
try
{
_t.Wait(1000);
}
catch (Exception ex)
{
Logger.LogError(_componentName, $"An exception occurred in a fire-and-forget task which was started at {_started}.\r\n" +
$"The original stack trace is:\r\n{_originalStacktrace}");
Logger.LogException(_componentName, ex);
}
try
{
_t.Dispose();
}
catch (Exception dex)
{
Logger.LogException(_componentName, dex);
}
}
Well, normally, it works.
Normally.
Not always...
And then the service crashes with an error entry in the Windows Event Log.
(That's also true for the solution in the first answer at SO).
Some more background.
The application is a highly configurable Windows Service. The function is called with Utilities.TaskExtensions.CreateAndStartTaskWithErrorLogging(() => DataStore.StoreSyncedData(data), Name);, where DataStore is set to a composite which in turn calls Parallel.ForEach(m_InnerDataStores, _store => { _store.StoreSyncedData(_syncedData); }); on its members. One of them writes a video with the Accord library, which sometimes causes an AccessViolation at <Module>.avcodec_encode_video2(libffmpeg.AVCodecContext*, libffmpeg.AVPacket*, libffmpeg.AVFrame*, Int32*), i.e. the exception may come from non-managed code. Perhaps 10% of these exceptions evade...
So my question is:
how should my function look like to catch those evading exceptions?
And extra upvotes if you can explain why my code (or the suggested solution at SO) fails.

Native exceptions thrown by unmanaged code that occured on a thread started by that unmanaged code can't be caught. That's most often originating from a COM-object.

Thanks for that hint. Since most of these exceptions are caught by the catch, that seems unlikely (the stack trace, regardless if logged by my logger or the Windows Event Log, shows always the same function, i.e. these are not different kinds of exception, only different instances of the same exception).
So, what are the circumstances that let 1 out of 10 of these exceptions evade?
Is it something in the Parallel.ForEach which may or may not use a different thread for the execution?

No, more likely to be a thread by unmanaged code; avcodec_encode_video2 it was? Does it use DirectX?
