I use the following code block with some more code inside the using block:
using (System.Drawing.Bitmap tempImg =
(System.Drawing.Bitmap)tempObj.GetDa
Finally I could find what was wrong in my code and would like to mention it here as I think it may be useful to someone....
As I have given a relative path in tempImg.Save, and after the user clicks 'Save' in SaveFileDialog, the actual path for tempImg.Save become :
Path specified by SaveFileDialog + the relative path
automatically.
Thus if the path does not exist, this error occurs.
Thanks every one for the answers.
