How do I get a screenshot of an entire Form, not just what is visible in the window ?

Could you attach your project (for 2 reasons) -
1) I have tried to make a form bigger than the screen in the past, and have never succeeded. Thus I am curious as to how you did that.
2) We can experiment with your project, and see if we can solve your problem.

The form is not bigger than the screen. The client area of the form is the one that is bigger that's why the form requires a scrollbar to navigate its contents.
