Terminates the connection established through AtlAdvise.
Important
This function cannot be used in applications that execute in the Windows Runtime.
HRESULT AtlUnadvise(
IUnknown* pUnkCP,
const IID& iid,
DWORD dw
);
Parameters
pUnkCP
[in] A pointer to the IUnknown of the object that the client is connected with.iid
[in] The GUID of the connection point. Typically, this is the same as the outgoing interface managed by the connection point.dw
[in] The cookie that uniquely identifies the connection.
Return Value
A standard HRESULT value.
Example
LPUNKNOWN m_pSourceUnk;
LPUNKNOWN m_pSinkUnk;
DWORD m_dwCustCookie;
// create source object
HRESULT hr = CoCreateInstance (CLSID_MyComponent, NULL, CLSCTX_ALL,
IID_IUnknown, (LPVOID*)&m_pSourceUnk);
ATLASSERT(SUCCEEDED(hr));
// Create sink object. CMySink is a CComObjectRootEx-derived class
// that implements the event interface methods.
CComObject<CMySink>* pSinkClass;
CComObject<CMySink>::CreateInstance(&pSinkClass);
hr = pSinkClass->QueryInterface (IID_IUnknown, (LPVOID*)&m_pSinkUnk);
ATLASSERT(SUCCEEDED(hr));
hr = AtlAdvise (m_pSourceUnk, m_pSinkUnk, __uuidof(_IMyComponentEvents), &m_dwCustCookie);
ATLASSERT(SUCCEEDED(hr));
// do something
CComBSTR bstrMsg(L"Hi there!");
((CMyComponent*)m_pSourceUnk)->Fire_ShowMyMsg(bstrMsg);
hr = AtlUnadvise (m_pSourceUnk, __uuidof(_IMyComponentEvents), m_dwCustCookie);
ATLASSERT(SUCCEEDED(hr));
