Problem with TimerCallback in.NET Compact Framework

Hi all,
I'm developing a PocketPC application using .NET CF.
In my application, I want to use timer callback ,so that after a specified
time interval I'm able to do some logging operation continuously.

I've implemented this and the build is also successful.
However, I observe the following:

When my application alone running it seems to log the details perfectly
on
to the specified file after a duration of 10 seconds as specified in the
callback function argument .

When I try to open another application at the same time, however logging
into the file stops and the timer no longer seems to be working.

I'm using a PDA with PocketPC2002 with PXA250 processor.
Can some please help?

Why is the timercallback not getting executed when I open any other
file/application?

NOTE: I'm not even trying to open the same file in which logging is
happening.

Any help is appreciated.

Thanks.

Below is the code I'm using to create the timer:
TimerCallback timerCollectDelegate =
new TimerCallback(charge.ChargeStatus);
System.Threading.Timer CollectTimer =
new System.Threading.Timer(timerCollectDelegate,
null, 0,
2000);
 
Hi,

did you (in your event function) stop the timer before doing your work - and restart it after this?
Otherwise you could get (depending on your code) an event while handling the event.....
Starting apps can slowdown the PPC for a while and than such a situation can happen.

You can prevent this by locking your code (a simple lock should do the job), or much easier
just stop the timer on entrance - and restart it when leaving.
