I am having a problem using the OnTimer class in my program. While the timer is running, none of the buttons that are on my GUI respond in a timely fashion. I am gussing this is because the timer is taking conrtol on the CPU, and the button click only reponds after the timer has completed its iteration. Is there a way to give the button clicks higher priority over the timer? I am trying to make it so the user can click on a button and not think that the program is locked up.

Timer Problem

OnTimer is the usual name for the handler method of the WM_TIMER message associated with timers. It is a message just like button click notifications. This means they are serialized -- same priority, first come first served.
What's probably happening is either:
a) You have set the timer period way too short, causing tons of WM_TIMER messages to flood your message pump.
b) You are doing something in the OnTimer method that is taking a long time. While any message, including WM_TIMER, is in process by a message handler, no other messages can get through (unless you reenter the message pump, like when you call DoModal on a dialog).
It might be a combination of the two. Try reducing the timer period. Also, think about making your program multi-threaded, and move what you're doing in the OnTimer handler to this other thread. Then you can make that thread lower priority if you wish.
