Thank you... PostMessage() works to turn off the display, but for some strange
reason it can't turn it back on. I set a 20 second delay, and precisely at 20
seconds my monitor light turns green, but then the monitor goes back to sleep
before the screen can be displayed. I'm guessing the signal is being sent to
turn on the monitor, but not to get windows out of power save mode... I also
see using -1 to turn the display back on is an un-documented feature. I can
get the display back on with a keystroke or moving the mouse, but I'm wanting
the program to turn the display back on without user input. Can anyone think
of any other way I could make my console application to turn the display back
on without user input?
I've tried
progname := FindWindow('displaycontrol', nil);
PostMessage(progname, WM_KEYDOWN, VK_F5, 0);
And while the key sent to the program, it does not wake the display up. I
see other examples of simulating keyboard input, but I haven't been able to get
them to work in a freepascal console application.
