Try this it disables several task switching keys.

SystemParametersInfo (SPI_SETSCREENSAVERRUNNING, TRUE, &nPreviousState, 0);

Note be sure to call false before closing your App.

SystemParametersInfo (SPI_SETSCREENSAVERRUNNING, FALSE, &nPreviousState, 0);

hi scooter1, unfortunately your solution's not working for NT, only Win9x...

hi zhangyunchao,

because it seems you have posted this question twice I post my comment here too,

you can use RegisterHotkey to do this, i.e.:

RegisterHotKey( m_hWnd, 1, MOD_ALT, VK_TAB );
RegisterHotKey( m_hWnd, 2, MOD_ALT, VK_F4 );

Add a pretranslate message on your WinApp. The sample below disables the Escape key so if im guessing correctly u can always  try getting the Macro for Alt-Tab and Alt-F4 to disable those 2 keys.

BOOL CYourApp::PreTranslateMessage(MSG* pMsg)
{
      if (pMsg->message == WM_KEYDOWN && pMsg->wParam == VK_ESCAPE) {
            return TRUE;
    } else  
          return CWinApp::PreTranslateMessage(pMsg);
      
}

ok.

MFCAnswer, I think the link doesn't point to anything new. All of these three possibilities where suggested earlier: SetWindowsHookEx, SystemParametersInfo and RegisterHotKey.

Seems we'll just have to wait if zhangyunchao will respond ...
