////////////////////
in win98:
Sometimes applications need to terminate a screen saver that is already running. In Windows 3.1 or Windows 95, a screen saver could be terminated easily by posting a WM_CLOSE message to the currently active screen saver window as in this example:
PostMessage (GetActiveWindow(), WM_CLOSE, 0, 0L);
//////////////////
WinNT or Win2K:
BOOL CALLBACK KillScreenSaverFunc(HWND hwnd, LPARAM lParam)
{
if(IsWindowVisible(hwnd))
PostMessage(hwnd, WM_CLOSE, 0, 0);
return TRUE;
}
HDESK hdesk;
hdesk = OpenDesktop(TEXT("Screen-saver"),
0,
FALSE,
DESKTOP_READOBJECTS | DESKTOP_WRITEOBJECTS);
if (hdesk)
{
EnumDesktopWindows(hdesk, KillScreenSaverFunc, 0);
CloseDesktop(hdesk);
}

HOWTO: Force a Screen Saver to Close Once Started in Windows NT
ID: Q140723
and another way
nRet = SystemParametersInfo (SPI_SETSCREENSAVEACTIVE,
0, NULL, 0);
will disable the screen saver.

程序启动时修改注册表值禁用屏保，
程序退出时再恢复回来。
