当然肯定是要实现IRichEditOleCallback这个接口，网上很多文章有这个介绍，

HRESULT STDMETHODCALLTYPE TRichEditOleCallback::QueryAcceptData(LPDATAOBJECT lpdataobj, CLIPFORMAT FAR *lpcfFormat,  DWORD reco, BOOL fReally, HGLOBAL hMetaPict){HRESULT result=S_OK;if (TRUE==fReally){FORMATETC tFormat={ 0xC007/*FileNameW*/, 0, DVASPECT_CONTENT, -1, TYMED_HGLOBAL };STGMEDIUM tSTGMEDIUM;ZeroMemory(&tSTGMEDIUM,  sizeof(STGMEDIUM));if (S_OK==lpdataobj->GetData(&tFormat,&tSTGMEDIUM)){LPOLESTR pstrData =(LPOLESTR)GlobalLock(tSTGMEDIUM.lpszFileName); //GlobalLock(tSTGMEDIUM.lpszFileName);/*USES_CONVERSION;  CString strFileName =OLE2T(pstrData);HYPERLINKINFO linkInfo;NMHDR header;header.hwndFrom = m_RichEditCtrl->m_hWnd ;header.idFrom   = m_RichEditCtrl->GetDlgCtrlID();header.code     = 0xFFFF;m_RichEditCtrl->GetParent()->SendMessage(WM_NOTIFY,(WPARAM)strFileName.GetBuffer(0),(LPARAM)&header);*/GlobalUnlock(tSTGMEDIUM.lpszFileName);ReleaseStgMedium(&tSTGMEDIUM);return S_FALSE;}}return S_OK;}
