I was using a code, to draw the image on the screen. But I am not able to figure out why it is not being drawn on the screen. I am using the following code,

C#

Bitmap bmp = new Bitmap("10630606_727195303982470_1655175415434850365_o.jpg");
Graphics gr = Graphics.FromImage(bmp);
gr.DrawImage(bmp, 60, 30);

..if I add a new line at the end of the code, as

C#

bmp.Save("<location>");

..then I can still find out the file created at that location. Which means that the code was working find and the image was loaded. But the graphics aren't drawn on the screen. I am having a WPF application of 900x700 size but the image or any thing is not found anywhere on the screen in that application.

Any help will be appreciated.

Afzaal,

In the code you show, you don't do any attempt to show anything on screen. Besides, it does not look like WPF code. Yes, you can use System.Drawing.Graphics with WPF, but this is irrelevant to your question. Even if you tried to draw some image on screen, we cannot see this code; so how anyone can help you based on your information?

Yes Sergey, you're right. This is a part of Windows Forms and from System.Drawing.dll. I am sorry, I forgot to mention that part. However, the code that I am using is from the MSDN documentation, http://msdn.microsoft.com/en-us/library/42807xh1(v=vs.110).aspx you can see that they're having a commentary label "// Draw image to screen." So, I thought this might be a draw image on screen and show in the application type of thing. I guess, I am wrong?

Thank you. You still just need to prepare some code sample, as small as possible but comprehensive, with the steps to reproduce the problem.

Please see my comments to the question. I did not see your code; there can be too many ways to screw up things. You did not show any code where you tried to draw anything on screen; and drawing on a bitmap you show is pretty much irrelevant.

However, first check the problems which looked similar and my past answers:

Chances are, you can get a clue from those answers.
