Develop app. for Pocket PC by VB .NET

Hi,

Now, I'm developing application for running in Pocket PC by using VB .NET. I got some problem when I close the form. my app is not raise Closed and Closing events when I close form and the application is not exit or stop after I've closed all form. If I set MaximizeBox and MinimizeBox to false the app. will close with code 0 (that's what I want). What should I do to solve these problems?

Thank you,
