This is exactly what I am doing, but it seems that PrgUserCancel never gets
called. Any idea why?
I check the return value of PrgHandleEvent to see if it was a cancel, but
this never happens.

I don't think so.

You need to detect when the Progress Manager goes into "cancel mode" and
abort the operation in progress, cleaning up as necessary. The Progress
Manager doesn't know how to abort the process cleanly since it has no idea
what the process is. See the macro PrgUserCancel. If PrgHandleEvent returns
false, you should call PrgUserCancel to check whether the user pressed the
Cancel button. If he did, you should start the abort process. Depending on
what the main process is, this can be complex or trivial. You should update
the progress dialog: your callback function should display an appropriate
"Cancelling..." message while you're aborting.
