Hi,
I have created the "screen saver" for OS Windows, but it ignores option "turn off monitor" (Display properties -> tab Screen saver -> Power) and running anyway :confused: .

My code based on DirectX SDK example.

I process this messages:

case WM_ACTIVATEAPP:
    if( wParam == FALSE && m_SaverMode != sm_test )
        InterruptSaver();
    break;

case WM_POWERBROADCAST:
    if( wParam == PBT_APMSUSPEND && m_VerifySaverPassword == NULL )
        InterruptSaver();
    break;

case WM_SYSCOMMAND:
    if ( m_SaverMode == sm_full )
    {
        switch ( wParam )
        {
            case SC_NEXTWINDOW:
            case SC_PREVWINDOW:
            case SC_SCREENSAVE:
            case SC_CLOSE:
                return FALSE;
        };
    }
    break;

Thank you.

What happens when you select "turn off monitor". Where in your code do you action that selector, what actions does your code take? Please do not expect people to guess how your code works.

Hi,
Display properties -> tab Screen saver -> Power
I do nothing :). This is must start automatically, but my screen saver is blocked this.

I have found the problem :) .
In window procedure:

case WM_SYSCOMMAND:

switch ( wParam )
{
case SC_MONITORPOWER:
return DefWindowProc(hWnd, message, wParam, lParam);
//was: return 0;
};
