定义 CreateControlSite 接口

ExpView.h

class CExpView : public CHtmlView{...........省略.....public:virtual BOOL CreateControlSite(COleControlContainer* pContainer,COleControlSite** ppSite, UINT nID, REFCLSID clsid);};

ExpView.cpp

BOOL CExpView::CreateControlSite(COleControlContainer* pContainer, COleControlSite** ppSite, UINT nID, REFCLSID clsid){// TODO:  在此添加专用代码和/或调用基类ASSERT(ppSite != NULL);*ppSite = new CSiteControlSite(pContainer);return TRUE;}
