Invisible Form
This code will simply allow you to create a form which is clear, meaning you can only see the controls on the form, and everything else will appear as whatever ur form is covering up. The best thing about this code is that if you click on an area of the form which has no controls, and is transparent, then it will take you to that window. MAKE SURE YOUR FORM SCALEMODE IS PIXELS
