MSTSCLib :: MsRdpClient错误行为

Question

我正在尝试使用MsRdpClient连接到rdp服务器，并收到一些基本通知。现在，我遇到了同样的问题，人们已经有大约8年的时间了，但没有找到任何答案，因此我再次提出了这个话题。我所拥有的就是这样的代码，这些代码来自有关如何在Winapi中使用rdp的各种示例：

#include <Windows.h>
#include <CommCtrl.h>
#include <tchar.h>
#include "resource.h"
#include <atlbase.h>
#include <exdisp.h>

#include "mstscax.tlh"
#include "mstscax.tli"
using namespace MSTSCLib;

        hr = pTscAx->QueryInterface(IID_IConnectionPointContainer, (LPVOID *)&cpCPCont);
        if (FAILED(hr))
            return FALSE;
        hr = cpCPCont->FindConnectionPoint(__uuidof(IMsTscAxEvents), &m_cpConnect);
        if (FAILED(hr))
        {

好的，所以我在这段代码中做什么。我创建一个窗口，创建一个MSTSCLib::IMsRdpClient2* pInterface对象，将事件接收器类附加到捕获事件到该对象，然后将无效数据传递给该对象。但是，不会触发任何事件，OnFatalError，OnConnecting等，也不会被调用，并且无论服务器/用户/密码是什么，HRESULT hrConnect = pInterface->Connect();总是返回S_OK。据我了解，此行为与Invoke中的CTscEventSink实现有关，我需要在这里做一些事情：

STDMETHOD(Invoke)(DISPID dispidMember, REFIID riid, LCID lcid, WORD wFlags,
    DISPPARAMS FAR* pdispparams, VARIANT FAR* pvarResult,
    EXCEPINFO FAR* pexcepinfo, UINT FAR* puArgErr)
{

    return S_OK;
}

我需要做一些事情，而不是仅仅返回S_OK来进一步传递connect命令。有人可以帮忙吗，我需要在这里做什么？喜欢从Invoke打电话来吗？这太麻烦了，我不知道任何示例，也没有msdn页对此有所说明。
