Thanks for your help.

This is from using the F1 key help on Sendkeys:
Note SendKeys can't send keystrokes to an application that is not designed to
run in Microsoft Windows. Sendkeys also can't send the Print Screen (PRTSC)
key to any application.
The only way I know would be to write a DLL that get the PrtSc key
identification code and sends an interrupt to it. If you are not familiar
with "C" then ask a C programmer around if they could write a quick DLL for
you.
