This is my code....Picture box shows empty

System.Net.WebRequest request = System.Net.WebRequest.Create(""); System.Net.WebResponse response = request.GetResponse(); System.IO.Stream responseStream = response.GetResponseStream(); Bitmap bitmap2 = new Bitmap(responseStream); pictureBox11.Image = bitmap2;

What I have tried:

If you had bothered to do what I told you last time you posted this question: Load a image from URL to picture box using[^] you would have seen what was going on: it's a PNG image. And a quick test with your code shows it works. Except ... you didn't read the documentation: Image.FromStream Method (System.Drawing) | Microsoft Docs[^] which clearly states:
You must keep the stream open for the lifetime of the Image.
You don't. You specifically Dispose the stream once you have created the Bitmap, which means the image is no longer valid.

Go back to your existing code, create Bitmap object, use the debugger to prove it is correct - as I suggested yesterday - and then copy the image to a new bitmap before you Dispose the Stream.

A quick check with the debugger would have shown you that the image was valid inside the using block and invalid outside it a day ago ... so why didn't you try using it?

not all code faults give error messages - that's why you use the debugger to see exactly what *is* going on. It lets you look at (or even change) variables while you code is executing, run your app line by line, and so on.
Error messages just tell you a fatal error happened at some point in the past, they are a tiny percentage of actual bugs!

Learn to use the debugger - it will save you hours of work and hair pulling frustration!
