6.18. How can I put an icon on the title bar regardless of the which form is active?
This is not supported with the current version of the .NET Compact Framework. You can, however, P/Invoke Pocket PC's notificaiton system to do this. Refer to the following for more information:
Sample Code:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnppc2k2/html/ppc_fications.asp
AYGShell APIs:
The native Notification APIs are: SHNotificationAdd, SHNotificationRemove, SHNotificationGetData, and SHNotificationUpdate.
6.19. How do I disable and capture hardware buttons?
Refer to the sample in the P/Invoke library.
http://msdn.microsoft.com/library/en-us/dnnetcomp/html/PInvokeLib.asp#PInvokeLib_Topic03
6.20. How do I hide the start icon?
The Start icon can be hidden using the SHFullScreen API. //C#
const uint SHFS_SHOWTASKBAR = 0x0001;
const uint SHFS_HIDETASKBAR = 0x0002;
const uint SHFS_SHOWSIPBUTTON = 0x0004;
const uint SHFS_HIDESIPBUTTON = 0x0008;
const uint SHFS_SHOWSTARTICON = 0x0010;
const uint SHFS_HIDESTARTICON = 0x0020;
