Problem with Timers

[lucbrunet]

Hi, I have a form (frmForm) with a timer on it, and also an additional class (clsClass.vb). When I run the timer using a button on the form it works fine, but the minute I call a method from my class the timer_click event stops running at the set interval. I've checked and the enabled property is still set to true, but the timer event just no longer runs.

Also, if I put a msgbox inside the method in clsClass, the timer continues to run until I press 'ok' on the message box. This leaves me to believe that the problem lies when the code returns from the class to the form. Has anyone experienced anything like this?

The Windows Forms timer is single-threaded and runs synchronously with other code on the thread; in other words. I suspect that what's happening is that your clsClass code (also running on the same thread, I presume) takes priority and therefore the timer won't fire. The solution is to either start clsClass on a separate thread or use a System.Timers.Timers timer. If you choose to do the latter, read this first: http://msdn.microsoft.com/msdnmag/is...T/default.aspx.

Thanks for the reply! I actually changed the timer to a ccrpTimer and it works fine, so I don't know for sure what the problem was, maybe it was the priority of the threads like you said.
