方法基本同Knowledge Base文章Q220844HOWTO: Insert a Bitmap Into an RTF Document Using the RichEdit Control 只是在最后插入之前调用一下IOleCache::SetData,用一个HGLOBAL作为参数，HGLOBAL里面的数据是一个METAFILEPICT结构，包含自己提供的图片
ASSERT_VALID(this); ASSERT(m_lpObject != NULL); // get IOleCache interface LPOLECACHE lpOleCache = QUERYINTERFACE(m_lpObject, IOleCache); if (lpOleCache == NULL) { TRACE0("Warning: object does not support IOleCache interface.\n"); return FALSE; } ASSERT(lpOleCache != NULL); // new cache is for CF_METAFILEPICT, DVASPECT_ICON FORMATETC formatEtc; formatEtc.cfFormat = CF_METAFILEPICT; formatEtc.ptd = NULL; formatEtc.dwAspect = DVASPECT_ICON; formatEtc.lindex = -1; formatEtc.tymed = TYMED_MFPICT; // setup the cache so iconic aspect is now included DWORD dwConnection; SCODE sc = lpOleCache->Cache(&formatEtc, ADVF_NODATA|ADVF_PRIMEFIRST|ADVF_ONLYONCE, &dwConnection); if (FAILED(sc)) { lpOleCache->Release(); return FALSE; } // set data if iconic image provided if (hMetaPict != NULL) { STGMEDIUM stgMedium; stgMedium.tymed = TYMED_MFPICT; stgMedium.hGlobal = hMetaPict; stgMedium.pUnkForRelease = NULL; sc = lpOleCache->SetData(&formatEtc, &stgMedium, FALSE); if (FAILED(sc)) { lpOleCache->Release(); return FALSE; } } lpOleCache->Release(); return TRUE;
