Tom-

>I have an app that using a timer control I simulate a loop. The loop, using a windows api calls Carbon Copy 32 to initiate file transfers. I need to find a way to break the app out of the loop to it's 'paused' state. (When the timer is counting.) I would like this to be done with a command button to keep the user interface simple for the not so intelligent user. Any ideas?

Here a simple example that will show you one way to pause a loop. It uses two buttons--one to start a loop and one to stop it. You'll need to adapt it, of course, to your specific case. HTH
