Does this info tell you anything about why my app hangs the operating system?

M

MCM

Windows CE 5.0 (Eurotech BitsyXb) system running a heavily graphical
application with several user-drawn controls.

The application is a C# (.NET CF 2.0) application written in Visual Studio
2008 with some OpenNETCF.

After about 4 hours, the application freezes and Windows is frozen as well -
the only thing I can do is power down. (The mouse pointer won't move and
ActiveSync won't let me access the device.)

Threads (that I know of):
1. A Keypad monitoring thread (OpenNETCF thread)
2. A thread watching for Sleep mode (OpenNETCF thread)
3. A thread that is doing ModBus (RS-232) communication (not sure the
origin, though I think System.Threading)
4 Main Application thread (three timers running; one of which is a timer
running in an animation control)

Output Window Excerpts:
A first chance exception of type 'System.NullReferenceException' occurred in
System.Drawing.dll
A first chance exception of type 'System.InvalidCastException' occurred in
System.Drawing.dll

The obvious first step is to disable each thread, one at a time, and see
which causes the problem to go away or change its behavior. Why do you have
a keypad monitoring thread? Doesn't the keypad send suitable WM_ messages
for its keys via its driver? I'd start with that one...

The "lots of these" threads are a short-lived worker. I can't definitvely
say what they are without more info, but they wouldn't casue me concern
unless you don't expect workers to be running. The ThreadAbortException is
what you should be concerned about. What is calling Thread.Abort()? I just
checked and it's not called anywhere in the OpenNETCF.WindowsCE.Messaging
assembly.
