Subject: Add() Method Sender: mutafchiev@gmx.de 12.06.07 05:04 Hello, I have a question about MFNode.Add() method. I create a "Switch" node and an "IndexedFaceSet" node with: if(SUCCEEDED(this->m_Engine->CreateNode(L"IndexedFaceSet", L"IndexedFaceSetNode", &vrmlLayer)))         AfxMessageBox(L"IndexedFaceSetNode created"); and add it to the "switch" node. I catch the "coord" field of the "IndexedFaceSet" node and cast it to IID_IMFNodeObject with: if(SUCCEEDED(pField->QueryInterface(IID_IMFNodeObject, (void**) &m_coordFMNode)))         AfxMessageBox(L"m_coordFMNode OK"); The problem occur when I want to add some "Coordinate" object to that field: VARIANT CoordVar; VariantInit(&CoordVar); CoordVar.vt = VT_ERROR; CoordVar.lVal = 0; if(SUCCEEDED(m_coordFMNode->Add(Coordinate, &CoordVar)))         AfxMessageBox(L"add Coordinate succeeded"); Could somebody tell me why and how can I prevent this problem. Tanks o lot!   [reply] [back to forum] [new message] [all forums] Add() Method / mutafchiev@gmx.de / 12.06.07 05:04      Re: Add() Method / nalex@parallelgaphics.com / 13.06.07 04:32          Re: Add() Method / mutafchiev@gmx.de / 13.06.07 05:53 Messages in thread: 3 [reply] [back to forum] [new message] [all forums]
