I want to know the procedure in Windows7 to make appear the screensaver when required and disappear when not.
did you find a solution for your question in the meantime? Please let us know!
I couldn't find anything that would force a screensaver to run when needed BUT you might want to check out a program called Outtasight. I think it can help in your case.
I'm not sure if this is what you are looking for, but I hope it helps.
Thank You,for the link u sent
But, i was not looking for this
Actually, i want to know that " a screen saver to appear when we require to hide a file copying process,etc. from without being seen"
