CE MAPI学习(二)结束一个MAPI SESSION

 
结束 MAPI Session
1.               IMAPISession::Logoff 方法结束 MAPI 会话 , 如下所示 :
hr = pSession->Logoff(0, 0, 0);
2.               减少 the MAPI session 引用总数, 通过在 MAPI session 对象上调用  IUnknown::Release 方法。
pSession->Release();
3.               Decrement the MAPI subsystem reference count, and delete any per-instance global data for the MAPI DLL with the MAPIUninitialize global MAPI function:
MAPIUninitialize();
 
Code Example
hr = pSession->Logoff(0, 0, 0);
if (hr != S_OK) {
    // Logoff failed.
    MessageBox(NULL,
               _T("Logoff failed."),
               _T("Warning"),
               MB_OK);
    exit(0); // 用异常处理代替
}
 
pSession->Release();
pSession = NULL;
MAPIUninitialize();
