Prevent Full Screen Applications From Drawing On A Windows Form

[Spaces]

I am working on a project using c# where I need a windows form to be on top of any open application. Since my form is docked, most issues are solved. My only problem I have is when certain full screen applications are started, they draw over top of my form. I would like to reach at least one of the following scenarios:
1.) Be able to notify the user and prompt whether or not to allow the full screen app.
2.) The best case scenario would be to allow the Full Screen Application but prevent it from drawing over my form.

If anyone knows of a solution/direction regardless of complexity please let me know. Thanks in advanced!

I don't have much input to help you, but read this msdn blog post...it gives some very good info about always on top which might help.

Thanks for that article, it was interesting and answered a few of my questions. I guess another question I have would be: can I define the area for full screen applications to run in. My program is always docked at the top so I would know the exact size it would need to be.
