:confused:Hi all, I have a small problem..I have an MFC application..and I want to enable screensaver or disable screensaver on meeting some condition...can I do it..I tried searching for it in google, codeproject etc..but hard luck...nothing is there..can anyone out there help me out...any help or pointers are highly appreciated.. Thanks a lot in advance.. Himanshu
Do you want to disable it permanently or just while your program is running? To disable it permanently, you might have to write to the registry or use
SystemParametersInfo(), although unless your program is specifically to change the screensaver, then most users won't like you doing this. To disable it temporarily, look atSetThreadExecutionState(ES_DISPLAYREQUIRED). This function is supported on Win98 or later. Hope this helps,Ryan

Oh, you want to start the screensaver running whenever you like? A screensaver is just an exe file on your hard-drive. The name of the screensaver file the user has selected is in the registry, at
"HKEY_CURRENT_USER\Control Panel\Desktop\SCRNSAVE.EXE". Read this value and pass it toShellExecute()and that will run the user's screensaver. Hope this helps,Ryan

Rage wrote: Hey, we are on CP here, the most *precise* web site about code stuff :rolleyes: OK, so how about mentioning that a screensaver doesn't actually have to have a .scr extension. Any executable file can be used as a screensaver (heck, even .bat files work :rolleyes: ). You can even setup VC++ as your screensaver if you want to :) beat that!! ;P

I have no idea what colour the sky is because I can't see it - all I see is more clouds than there are people in New York, and I'm hungry. PS. Did I mention I was hungry? :rolleyes:

If you want to start the currently configured screensaver, try this: PostMessage(GetForegroundWindow(), WM_SYSCOMMAND, SC_SCREENSAVE, 0); -------- There are 10 types of people in this world. Those who know binary and those who don't.
