Hello,

I’m new to the compact framework and mobile development and I need a
little help. I have a form that has a panel, in the panel there’s a
label that’s tied to a timer. The timer runs ever second. It’s a
countdown and the label is reacting as expected.

The problem is when I shutdown the app, the timer is still running and
I get an ObjectDisposedException Error. I can prevent it from crashing
if I do a try catch in the timers tick method and catch that Exception
type. The problem with that is when I try to launch the app again, it
hangs. I have to do a soft reset in order to start the app again.

Anyone have any suggestions as to what I can do to resolve this?

Thanks in advance,

Kris
 
What kind of a Timer (Thread or Forms)? Why not stop the timer when you
close the Form or when the Form is disposed?

Its a form timer

I tried to override the forms closing. but it doesnt seem to fire even
in debug.


Thanks,

Use "OnClosing" (just type override and VS will do the rest for you).
However, as Chris alludes to, you should use Windows.Forms.Timer - that way
you won't have the problem of it not starting.
