Thread: putting screen in stand-by

    putting screen in stand-by

    I have actually two questions:

    1)Is there a way to put the screen in stand-by
    I guess there must be because windows can do it, I just don't kow it

    2)Also, is there a way to start up the screensaver? like when you press the example button in the screensaver section in the desktop poperties.


    thx

    SystemParametersInfo()

    Take a look at SPI_SETPOWEROFFACTIVE and SPI_SETSCREENSAVEACTIVE.

    One of my first, simplest and most useful windows programs.
    Code:
    #include <windows.h>
    
    int APIENTRY WinMain(HINSTANCE hinst, HINSTANCE hinstPrev, LPSTR lpCmdLine, int nCmdShow)
    {
    
    // Give user time to take hand away from mouse
    Sleep(atoi(lpCmdLine) * 1000);
    
    // Try setting below to SC_MONITORPOWER for standby
    SendMessage(GetDesktopWindow(), WM_SYSCOMMAND, SC_SCREENSAVE, 0);
    
    return TRUE;
    }

    same result here .

    Although the function succeeds (return value != 0) it doesn't give me the result it should.

    I'll try the screensaver function later today.

    Thanks for the effort/advice guy

    edit couldn't wait for later today
    the screensaver works as you said it would
    and also the SC_MONITORPOWER works.
    this will put my monitor off:
    SendMessage(GetDesktopWindow(), WM_SYSCOMMAND, SC_MONITORPOWER, 2);

    thanks guys

    SC_MONITORPOWER - Awsome!

    Never even noticed that one in the WM_SYSCOMMAND reference.
