>I have a grid that displays sensitive corporate data that should be protected against copying by screenshot appliations. Any suggestions? I have tried to intercept key stroke(s) but have been unsuccessful. (Hot keys for one screenshot program used by the enterprise are CTRL 4 which I can not interrupt via the KeyPress method of the grid control... KeyPreview of the form is set to .t.) Thanks to all.

Doyle, you have virtually no chance. You might be able to trap for the PrtSc key when *your* app is foremost and active but not when another app is. You may be able to disable PrtSc altogether but there are screen scrapper programs like Kleptomania and AquaDeskperience that will allow a user to very easily snapshot whatever region on the screen they like. The only way around that would be that your app checks running processes and exits itself if undesirable applications are running. But blacklist approaches are tough to implement effectively. Ultimately you need to change your focus from preventing screen dumps to implementing access control to the application and data in the first place.
