过一段时间消失的MessageBox(源自MSDN)
void CALLBACK MessageBoxTimer(HWND hwnd, UINT uiMsg, UINT idEvent, DWORD dwTime)
{
   PostQuitMessage(0);
}
UINT TimedMessageBox(HWND hwndParent, LPCTSTR ptszMessage, LPCTSTR ptszTitle, UINT flags, DWORD dwTimeout)
{
   MSG msg;
   UINT idTimer = SetTimer(NULL, 0, dwTimeout, (TIMERPROC)MessageBoxTimer);
   UINT uiResult = MessageBox(hwndParent, ptszMessage, ptszTitle, flags);
   KillTimer(NULL, idTimer);
   if (PeekMessage(&msg, NULL, WM_QUIT, WM_QUIT, PM_REMOVE)) {
       uiResult = 0;//默认值
   }
   return uiResult;
}
使用方法同MessageBox，只是多了个DWORD参数 dwTimeout
 
4）微软以前未公开的函数
 
#include <windows.h>
#include <tchar.h>
