It's amazing how much time you've spent not learning how to use the
API calls, just in posting messages here.
It's a four-line function you add to your application, plus a bit of
error-trapping and call it with:
lcMyNewTempFileName = GTFN()
Here's my original program that does something a bit different from
what you're trying to do. See if you can adapt it for your needs.
Don't hesitate to ask questions.
