turn off monitor

[test_man]

Is there anyway to turn off/on monitor in CVI?

Hello Sheetal,

You can use the Windows SDK SendMessage function.

#include "windows.h"

HWND hwnd;

hwnd = (HWND)GetCVIWindowHandle();

To turn off the monitor: 
SendMessage(hwnd, WM_SYSCOMMAND, SC_MONITORPOWER, 2) ;

To put the monitor in standby:

SendMessage(hwnd, WM_SYSCOMMAND, SC_MONITORPOWER, 1) ;

To turn on the monitor:

SendMessage(hwnd, WM_SYSCOMMAND, SC_MONITORPOWER, -1) ;

More documentation on these functions can be found on MSDN.

Thanks.
