Annoying is your code, not exception. In what line?

It's got to be the FromStream line. That's a common exception with this particular method call.

Thank you; I understand but all inquirers should specify it if they want help. There are many cases when this is not apparent. Comprehensive exception report is needed.

pictureBox1.Image = System.Drawing.Image.FromStream(ms);

You've just posted the same line as he already has.

Try using the following instead, to validate that the stream data is valid:

C#

pictureBox1.Image = System.Drawing.Image.FromStream(ms, false, true);

i have tried this line and i get the same exception

That means that the code thinks it's not a valid image format. Try writing out the contents of the memory stream to a file instead, and see what's in there. Also, save it out to a file, and see if you can open that file with something like Paint.NET.

is there another way to select image from database and store it into picturebox ?
