Hi All
I want to ShellExecute a program repeatedly but not until the previous instance has finished, what's the best approach? So I effectively want to wait in a loop until the previous instance exits and then run it again.
Ideas?
TIA
Chris.

Look at command START /wait:
c:> start /?

Sounds like the Task Scheduler would suit you. It has an option to not run if there's an existing run in progress.
