怎么实现SetClientSite接口？ 请高手帮忙！

[guothreelove2003]

问题比较奇怪，我明明都写好了函数的定义和实现了，但编译时却报告这种错误。请大家帮帮忙，这里先给100分，我在这里http://community.csdn.net/Expert/topic/5044/5044648.xml?temp=.5452387 还开了个贴子，问题解决后两个贴子一起结。

头文件
class ATL_NO_VTABLE CSUploader :
public CComObjectRootEx<CComSingleThreadModel>,
public CComCoClass<CSUploader, &CLSID_SUploader>,
public ISupportErrorInfo,
public IOleObjectImpl<CSUploader>, //自己加的，可能不对
public IConnectionPointContainerImpl<CSUploader>,
public IDispatchImpl<ISUploader, &IID_ISUploader, &LIBID_SUPERUPLOADERLib>,
public CProxy_ISUploaderEvents< CSUploader >

{
public:
STDMETHOD (SetClientSite)(ConnectType eConnectType);

}

CPP文件：
STDMETHODIMP CSUploader::SetClientSite(ConnectType eConnectType)
{
return S_OK;
}


错误提示：
:\program files\microsoft visual studio\vc98\atl\include\atlctl.h(1661) : error C2039: 'IOleObject_SetClientSite' : is not a member of 'CSUploader'
