如何修改已插入到RichEdit里面的对象的属性?

[pioncare]

如题,
REOBJECT reobject;
ZeroMemory(&reobject, sizeof(REOBJECT));
reobject.cbStruct = sizeof(REOBJECT);
CLSID clsid;
sc = pOleObject->GetUserClassID(&clsid);
if (sc != S_OK)
AfxThrowOleException(sc);
reobject.clsid = clsid;
reobject.cp = REO_CP_SELECTION;
reobject.dvaspect = DVASPECT_CONTENT;
reobject.poleobj = pOleObject;
reobject.polesite = lpClientSite;
reobject.pstg = pStorage;
HRESULT hr = this->GetIRichEditOle()->InsertObject( &reobject );

在未插入图片对象时可先设定好其属性,问题是如果对象已经插入了,如何修改其属性呢?

已经知道可以获取对象的信息的方法:
IRichEditOle* pOle = GetIRichEditOle();
if(pOle)
{
REOBJECT object;
memset(&object,0,sizeof(REOBJECT));
object.cbStruct = sizeof(REOBJECT);

for(int i=pOle-> GetObjectCount()-1;i> =0;i--)
{
pOle-> GetObject(i,&object,REO_GETOBJ_ALL_INTERFACES);

LPOLEOBJECT lpObject = (LPOLEOBJECT)object.poleobj;
}
pOle-> Release();
}
