How to make UserControl the top (ZOrder) control?

Hello All!

I'd like to make an ActiveX control, wich changes its size at runtime. So I use the UserControl.Height property to make that change.

But after I resized my control, the other control which are 'near' to my control, so these controls don't become invisible, I can see them 'in' (or over) my control.

Question: how can I make my control the top (in ZOrder) control, so the other control send to background?

Thx.

I've seen something like this for a login/menu combination where I think 2 different tabs were used to let one or the other tab show up using 'bring-to-front'.

good luck
