Re: Any Windows gurus out there?

Mark,

Your idea should work fine. The trick is how to simlulate mouse
movement or keypresses in order to disable the screen saver when
desired. ACE uses a Windows API call to move the mouse pointer in
order to achieve this same functionality. I seem to remember that it
may not work on all versions of Windows. But, I may be thinking of
something else. So, just try it.

VB declarations:

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)

Public Const MOUSEEVENTF_ABSOLUTE = &H8000
Public Const MOUSEEVENTF_LEFTDOWN = &H2
Public Const MOUSEEVENTF_LEFTUP = &H4
Public Const MOUSEEVENTF_MIDDLEDOWN = &H20
Public Const MOUSEEVENTF_MIDDLEUP = &H40
Public Const MOUSEEVENTF_MOVE = &H1
Public Const MOUSEEVENTF_RIGHTDOWN = &H8
Public Const MOUSEEVENTF_RIGHTUP = &H10

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

left click:
wParam = x_position
lParam = y_position
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 click:
wParam = x_position
lParam = y_position
Call mouse_event(MOUSEEVENTF_MOVE Or MOUSEEVENTF_ABSOLUTE Or
MOUSEEVENTF_MIDDLEDOWN, wParam, lParam, 0, 0)
Call mouse_event(MOUSEEVENTF_MOVE Or MOUSEEVENTF_ABSOLUTE Or
MOUSEEVENTF_MIDDLEUP, wParam, lParam, 0, 0)

right click:
wParam = x_position
lParam = y_position
Call mouse_event(MOUSEEVENTF_MOVE Or MOUSEEVENTF_ABSOLUTE Or
MOUSEEVENTF_MIDDLEDOWN, wParam, lParam, 0, 0)
Call mouse_event(MOUSEEVENTF_MOVE Or MOUSEEVENTF_ABSOLUTE Or
MOUSEEVENTF_MIDDLEUP, wParam, lParam, 0, 0)
