Scott,

Here is some code I use in ACE (written in VB6) in order to move the mouse
and click mouse buttons.  In most cases, they de-activate the screen saver.
These are all Windows API functions so you can call them from C too.

Move the mouse to center of screen:
Call mouse_event(MOUSEEVENTF_MOVE Or MOUSEEVENTF_ABSOLUTE, 32000, 32000, 0,
0)

Move mouse to specific screen location:
Call mouse_event(MOUSEEVENTF_MOVE Or MOUSEEVENTF_ABSOLUTE, wParam, lParam,
0, 0)

Left button click:
Call mouse_event(MOUSEEVENTF_MOVE Or MOUSEEVENTF_ABSOLUTE Or
MOUSEEVENTF_LEFTDOWN, wParam, lParam, 0, 0)
Call mouse_event(MOUSEEVENTF_MOVE Or MOUSEEVENTF_ABSOLUTE Or
MOUSEEVENTF_LEFTUP, wParam, lParam, 0, 0)

Middle and right buttons clicks are done the same way, just use MIDDLExxx
and RIGHTxxx.

Declaration for mouse_event subroutine:
Public Declare Sub mouse_event Lib "user32" (ByVal dwFlags As Long, ByVal dX
As Long, ByVal dY As Long, ByVal cButtons As Long, ByVal dwExtraInfo As
Long)

Have fun!
