 HWND g_hwndTimedOwner = 0; 
 BOOL g_bTimedOut = 0; 
void CALLBACK MessageBoxTimer(HWND hwnd,  
UINT uiMsg,  
UINT idEvent,  
DWORD dwTime) 
{ 
g_bTimedOut = TRUE; 
if (g_hwndTimedOwner) 
EnableWindow(g_hwndTimedOwner, TRUE); 
PostQuitMessage(0); 
} 
int TimedMessageBox(HWND hwndOwner, 
LPCTSTR pszMessage, 
LPCTSTR pszTitle, 
UINT flags, 
DWORD dwTimeout) 
{ 

UINT idTimer; 
int iResult; 


g_hwndTimedOwner = NULL; 
g_bTimedOut = FALSE; 


if (hwndOwner && IsWindowEnabled(hwndOwner)) 
g_hwndTimedOwner = hwndOwner; 


// Set a timer to dismiss the message box. 
idTimer = SetTimer(NULL, 0, dwTimeout, (TIMERPROC)MessageBoxTimer); 


iResult = MessageBox(hwndOwner, pszMessage, pszTitle, flags); 


// Finished with the timer. 
KillTimer(NULL, idTimer); 


// See if there is a WM_QUIT message in the queue if we timed out. 
// Eat the message so we do not quit the whole application. 
if (g_bTimedOut) 
{ 
MSG msg; 
PeekMessage(&msg, NULL, WM_QUIT, WM_QUIT, PM_REMOVE); 
iResult = -1; 
} 


return iResult; 

} 

用法：

TimedMessageBox( theApp.m_pMainWnd->m_hWnd,   CString("设置2000毫秒显示，然后自动关闭"),  _T("消息框标题"), MB_OK, 2000 );
