BTW, if you periodically call DO EVENTS in the loop, that also allows you to use a button on the form to signal the stopping of the process too (i.e. the Click() event would set the variable that's checked). Depending on how long the particulars of what you're doing in the loop, there may be cases where you may not always want to execute DO EVENTS for every loop iteration (the DO EVENTS does introduce a bit of a delay within the loop -- though it would impact the responsiveness of the control to stop the loop).
