Locking a screening

[Drathmar]

A client recently asked me if I could make a porgram that would have a fairly simple functionality, but with a catch. When the program is running he wants it to be the only program available. So a user couldn't alt tab and go to another program or minimize the program and open up a web broswer. To get out might require the user to hit escape and type in a password. I call it "Locking" but maybe there's already a phrase for this type of functionality. Is there? Drathmar

The program could make itself topmost, I guess. It could also grab the input focus whenever it loses it.

This could be done, but it is better left to Group Policy to do this. There are LOTS of ways to get around this "lock", and your app won't be able to cover them all.

When you say to leave it to Group Policy? I don't exactly follow, how would you do this with "Group Policy"?

Pick up the Windows XP Resource Kit and you'll find out. It's covered in about half of the book. But, to give you a quick look-see, click Start, Run, then type gpedit.msc and Hit enter.
