Today's tip for the compact framework is a simple one. Suppose you are working on a PPC device that only has two or 3 buttons, most likely the built in "calendar" and "task" type buttons. Your users would rather not use the screen/stylus as much as possible. Yes, you still have to build a user interface with tabbing, space bar, enter, etc. For example, suppose you use MessageBox to indicate an error; with no space bar or enter key you can clear it by using OpenNetCF's windows message filter to catch the key event. Then, you can PInvoke keybd_event to send whatever other message you want to your application. For example, the enter key (Key code 13) to hit "OK" on your message box.

[DllImport("coredll.dll")]

public static extern void keybd_event(byte vKey, byte bScan, uint dwFlags, uint dwExtraInfo);

That's all for today. Hopfully my other furnace doesn't blow up this weekend and I get some work done on TRAP.
