avoiding game draw on nav bar

[rcook]

I've got a C/C++ app on Win Mobile 5 developed in Visual Studio 2005 that uses direct draw to obtain pointers to memory containing the pixels I want to mess with and puts them on the screen. It's working.

It works in full screen mode right now. I found how to get the "client area", so I can limit my messing to the screen above the soft key menus at the bottom.

What is the correct system way to avoid writing on the nav bar at the top of the screen? I can't find where to get the size of that. I've searched the documentation only to find calls and flags that are new to Windows Vista, and I'm running on Win Mobile 5. Can someone please point me to the right place to look this up?

thanks,
