一个难题：关于OCX控件在IE中取得所在页面的URL.

[zhuangzl]

以下为在网上找到的例子,但出错.

HRESULT hrResult = S_FALSE;
IOleClientSite *pClientSite = NULL;
IMoniker* pMoniker = NULL;
LPOLESTR sDisplayName;

pClientSite = GetClientSite(); //出错， 返加NULL值

hrResult = pClientSite ->GetMoniker(OLEGETMONIKER_TEMPFORUSER,
OLEWHICHMK_CONTAINER,
&pMoniker);
if(SUCCEEDED(hrResult))
{
hrResult = pMoniker->GetDisplayName(NULL,
NULL,
&sDisplayName);
pMoniker->Release();
}

望高手能指点。

CComPtr<IOleContainer> spContainer;
spClientSite->GetContainer(&spContainer);
CComQIPtr<IHTMLDocument2, &IID_IHTMLDocument2> spDoc(spContainer);
if (spDoc)
{
BSTR bstrDomain;
if(SUCCEEDED(spDoc->get_domain(&bstrDomain)))
{

bstrDomain就是网址了
}
}
