[RESOLVED] noob question i think

I have looked on the faq before i made this thread but i cant seemto find what i'm after.

In the faq i have found the code to make the form stay on top of others,but i am trying to do the opposite. I want my form to be at the very back, so my other forms load on top of it and other programs stay on top of it.

I am trying to make a shell replacement, so the form is basicly the desktop, when i load up a program using my shell replacement it loads ok, but if i minimise it i cant get it back up because it stays behind the form.
