Slow_learner,

I am actually enquiring about Windows forms not ASP. Thanks for the info though.

I have run programs in the past where the PrtScrn key has not worked. Somehow the programmer has managed to disable it. Maybe even if there's a way to know when the user presses this key, it might then be possible to clear the clipboard????

Anyone?

PT_Exorcist,

thanks heaps for that. I will try it and see.
