Win 9X下用调用SystemParametersInfo,在Win2000下无效。 Private Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, lpvParam As Any, ByVal fuWinIni As Long) As Long Private Const SPI_SCREENSAVERRUNNING = 97 Private Sub cmdEnable_Click() '使Ctrl+Alt+Del有效 SystemParametersInfo SPI_SCREENSAVERRUNNING, True, p, 0 End Sub Private Sub cmdDisable_Click() '使Ctrl+Alt+Del无效 SystemParametersInfo SPI_SCREENSAVERRUNNING, False, p, 0 End Sub 。
