I recently finished a project but was then asked to make it into a service. I hit a problem in that I need to put the monitor into standby mode as part of this and odviously can't use the usual as there is no window to send a message to. SendMessage( hWnd, WM_SYSCOMMAND, SC_MONITORPOWER, (LPARAM)2 ); Is there a more direct way of getting the same functionallity that would work in a service and if so how? Thanks for any help given. Joe.
If you don't have a window to SendMessage to, you can send the message to all top-level windows : Code: SendMessage(HWND_BROADCAST, WM_SYSCOMMAND, SC_MONITORPOWER, (LPARAM)2 ); or, you can also use GetDesktopWindow to send message to the desktop window. Hope that would be helpful
I've already tried the first and it doesn't compile because not only does a service have to run without its own window but also has to run without a windows messaging loop. I'll give the later a try tomorrow and will let you know if it works. Joe.
