Form always on top behavior - vb.net

Hi all,

I'm programming an addin with a form and I'd like the form stay on top of ArcMap. The always on top property of the form makes it always on top of every window I have open.

I'd like it to behave like all the other ArcMap forms do:
Only the top most form when they have focus.
Always on top of ArcMap.
Never on top of other open programs that have focus.

Thank you,
