실제 함수 사용 예 int iRet = 0; UINT uiFlags = MB_OK | MB_SETFOREGROUND | MB_SYSTEMMODAL | MB_ICONINFORMATION; iRet = MessageBoxTimeout(NULL, _T("Test a timeout of 2 seconds."), _T("MessageBoxTimeout Test"), uiFlags, 0, 2000); //iRet will = 1 uiFlags = MB_YESNO | MB_SETFOREGROUND | MB_SYSTEMMODAL | MB_ICONINFORMATION; iRet = MessageBoxTimeout(NULL, _T("Test a timeout of 5 seconds."), _T("MessageBoxTimeout Test"), uiFlags, 0, 5000);
