求助：IRapiSinK的问题，搞不懂啊,懂的进来看看！进来的有分，解决的高分（60分-80分）相送

我调用IRAPIDesktop类成员HRESULT Advise(IRAPISink* pISink,DWORD* pdwContext);去注册连接事件；但不知道Advise()函数里的第1个参数pISink指针怎样取得，懂的帮帮忙啊

DWORD dwtext=NOERROR;
	HRESULT hr = S_OK;
	// Initialize COM.
	//hr = CoInitializeEx(NULL, COINIT_MULTITHREADED);
	clearSession();
	addNewInfo(_T("Try to connect a device....."));
	CoInitialize(NULL);
	// Create an instance of the IRAPIDesktop interface.
	hr = CoCreateInstance(CLSID_RAPI,
		NULL,
		CLSCTX_INPROC_SERVER,
		IID_IRAPIDesktop,
		(void**)&mpIRapiDesktop);

	if (hr ==0 && mpIRapiDesktop)
	{
		addNewInfo(_T("CoCreateInstance success"));
	}else{
		addNewInfo(_T("CoCreateInstance failure"));
		return ;
	}

	hr=mpIRapiDesktop->Advise(mpIRapiSink,&dwtext);

Use the following steps to initialize RAPI2 and create a session with a connected device.

1. Instantiate the IRAPIDesktop interface using COM's CoInitializeEx method.
2. Call IRAPIDesktop::Advise to register your applications implementation of the IRAPISink interface. This will alert your application when a device connects.
3. Once a device has connected, call IRAPIDesktop::EnumDevices to obtain an instance of the IRAPIEnumDevices interface.
4. Call IRAPIEnumDevices::Next to obtain an instance of the IRAPIDevice interface. This interface can be used to query for information about the selected device.
5. Call IRAPIDevice::CreateSession to establish a session with the selected device.
6. Initialize the underlying communications layer for the session by calling IRAPISession::CeRapiInit.
7. Call methods of the IRAPISession interface to perform operations on the connected device.

上面的实现我知道,但我现在要实现的Advise函数就是不清楚第一个参数IRAPISink×怎么获得。怎么样取得IRAPSink这个类的初始值

[oyljerry]

查找你对应的连接点信息..然后连接
void CConnClientDlg::OnConnect()
{
if(m_dwCookie!=0)
{
return;
}

if(m_pIUnknown!=NULL)
{
HRESULT hResult;
hResult = m_pIUnknown->QueryInterface(IID_IConnectionPointContainer,
(void**)&pConnPtCont);
if(FAILED(hResult))
{
::AfxMessageBox("不能获取对象的IConnectionPointContainer接口!");
return;
}

ASSERT(pConnPtCont!=NULL);

hResult = pConnPtCont->FindConnectionPoint(IID_IEventSink,&pConnPt);
if(FAILED(hResult))
{
pConnPtCont->Release();
::AfxMessageBox("不能获取对象的IEventSink连接点接口!");
return;
}

ASSERT(pConnPt!=NULL);

//获取事件接收器指针

IUnknown* pIEventSink;

m_xEventSink.QueryInterface(IID_IUnknown,(void**)&pIEventSink);

//通过连接点接口的Advise方法将事件接收器指针传给可连接对象

if(SUCCEEDED(pConnPt->Advise(pIEventSink,&m_dwCookie)))
{
::AfxMessageBox("与可连接对象ConnObject建立连接成功!");
}
else
{
::AfxMessageBox("不能与ConnObject建立连接!");
}
pConnPt->Release();
pConnPtCont->Release();
return;
}

IRAPISink必须由你自己实现，然后作为第一个参数。你不实现怎么接收通知？

[xin_zzq1]

谢谢啊·我还以为IRAPISink系统提供呢，

[xin_zzq1]

有高手知道IRAPISink怎么样实现吗？说下大概也可以！！

[xin_zzq1]

第一次搞～一点头绪都没啊
