WIndows Mobile full screen problem

I have a windows mobile professional 6.1 applica开发者_StackOverflow中文版tion and I want it to be full screen in all pages so I put the code below into my every pages constructor;

this.WindowState = FormWindowState.Maximized;

this works OK but "sometimes" for example when I use

MessageBox.Show("alert"); 

or when I try to connect internet within application and there is a problem and Windows shows me some messages popping up from the top of the screen..in this cases I lose my full screen and the top menu bar of windows becomes visible again..

any ideas?

You can use SHFullScreen to hide the start icon and other system areas of the screen. There is an undocumented function named AllKeys which will allow you to block some of the hardware keys (notes, recorder, green + red phone keys) from running. It will require a lot of work because there are many ways to run programs and the taskbar has a habit of reappearing after a program is run. Simply calling SHFullScreen once is not enough. You'll have to handle WM_ACTIVATE messages and call SHFullScreen again and force your program to the top again. It's a struggle against the operating system to have a true kiosk application on Windows Mobile.

Getting an app to "kiosk mode" in Windows Mobile is challenging becasue the platform simply isn't designed for it. This page has a lot of links to resources of getting it working. Using your favorite search engine to look for "compact framework kiosk mode" is likely to bring up more as well.
