What have you done so far? What sort of object are your drawing onto?

Ok, so glancing through your code you have no reference to a second form. Create the form with a method to accept a Graphic object. Then when you want to triger this then you pass your object to the child form as a parameter and handle it. You say you have it working on your main form, so it should be pretty easy to transpose. Also You seam to be repeating your work in the case statement, try to extract this into a method.

Let me know how it goes and use the code tag to display your code, makes it a lot easier to read.
