IRichEditOle::GetObject 是怎么个用法

[bborn]

IRichEditOle::GetObject
怎么用啊

哪个给个例子

看了msdn 不知道第一个参数怎么用？
每次返回值都不成功

[trexoven]

iob
Zero-based index specifying which object to return information about. If this parameter is REO_IOB_USE_CP, information about the object at the character position specified by the REOBJECT structure is returned.

or (int i = 0; i < nCount; i++)
{
REOBJECT reobject;
ZeroMemory(&reobject, sizeof(REOBJECT));
reobject.cbStruct = sizeof(REOBJECT);

if (E_INVALIDARG == pOle->GetObject(i, &reobject, REO_GETOBJ_ALL_INTERFACES))
{
return;
}

IDataObject *pDataObject;
if (S_OK != reobject.poleobj->QueryInterface(IID_IDataObject, (void **)&pDataObject))
{

return;
}

FORMATETC fm;
STGMEDIUM sm;

pDataObject->GetData(&fm, &sm);
if (fm.cfFormat == CF_BITMAP) //得到位图的例子
{

}


}

reobject.cbStruct = sizeof(REOBJECT);
注意这句，是必须的，如果没有就会返回E_INVALIDARG
