How to get into PartDocument using C++ API?

[Anonymous]

Hi.

My name is WJ Lee, KOREA.

I Tried to access part document of ipt file.

My model has 1 Assembly file with 30 part model.

I want to access one of 30 part. 

So I tried this.

Application *app

app->get_ActiveDocument(&pDoc);

CComPtr<PartDocument> pPartDocument(pDoc);

But Active Document is iam document.

So I tried this

pAssemCompDef->get_Occurrences(&pCompOccs);

CComPtr<ComponentOccurrences> pCompOccs;
CComPtr<ComponentOccurrence> pCompOcc;

CComPtr<PartDocument> pPartDocument;

pCompOccs->get_Item(index_part, &pCompOcc);

pCompOcc->Definition()->get_Document(&pPartDocument);

But get_Document function variable needs 

get_Document (IDisPatch **p_result );

I Stucked here.

Is there any way to get pPartDocument from IDisPatch  ??

Or is there anyway to access part document?

I just access part document internaly.

In VBA I can access Partdocument file just like this.

Dim oPartDocument As PartDocument

RedimDim oPartDoc(number) As ComponentOccurrence

For Each oOcc In oCompDef.Occurrences
If oOcc.SubOccurrences.Count = 0 Then
iPartCount = iPartCount + 1
Set oPartDoc(iPartCount) = oOcc
Else
Call PartSet(oOcc, oPartDoc(), oPartName(), iPartCount) 
End If
Next

For i = 1 To oPartCoun

Set oPartDocument = oPartDoc(i).Definition.Document

Next

Thanks for reading.
