Dispose method not doing its job

[Merlynx]

I am using TimerCallback to call a method in an activex dll repeatedly. The
TimerCallback works fines but when i exit the program, it still shows up in
the taskmgr i.e still running. So i use the Dispose method to release
resource from the thread on closing but still it doesn't work. I was
thinking whether it was the dll the culprit, which is better out process or
something else?

static System.Threading.Timer tr;

private void run(object state){
long value = test.MonitorRAS();
switch(value){
case 1:MessageBox.Show("Connected");break;
case 0:MessageBox.Show
("Disconnected");break;
}
}

private void Callback(){
TimerCallback call = new TimerCallback(run);
tr = new System.Threading.Timer
(call,null,0,20);
}

Please post a complete repro, the snippet you posted doesn't show the
Dispose method's implementation.
Are you running this on a separate thread? If it is, make sure it's a
backgroud thread otherwise the process will not terminate if the threadproc
is in an endless loop.

The Dispose method is implemented in an event handler closing. No it is not
a background thread.

When I read this "the Dispose method to release resource from the thread on
closing but ", I assume you call Dispose from another thread than the Main
thread. Are you sure you return from the thread procedure after the call.
Remember non-background threads don't terminate when the main thread
terminates, this will prevent the process to terminate.
