Simple question, or is it?

How can I get the full filename of a part from an Occurance object?
I need to do this in C++ using Inventor Application object (not Apprentice,
but if this can be done differently using Apprentice, by all means tell me
that also 🙂

I have a recursive function(basically same as the GetOccurancesDispatch from
the SDK samples)
In some cases I need to get the Filename of a part 'behind' the occurance.
How would I do this?

Here is a stripped version of my recursive function...

HRESULT CTree::FillTree(HTREEITEM ParentItem, CTreeCtrl* pTreeToFill,
ComponentOccurrences* pIncomingOccurances)

Result = pIncomingOccurances->get_Count(&nOccMax);

for(long nOccuCount = 1; nOccuCount <= nOccMax;++nOccuCount){

CComPtr pOccu;
CComPtr pOcEn;

HTREEITEM LocalItem;
pOccu = pIncomingOccurances->GetItem(nOccuCount);
strName = (LPCSTR)pOccu->Get_DisplayName();

if(pOccu->GetDefinitionDocumentType() == kAssemblyDocumentObject)
LocalItem = pTreeToFill->InsertItem(strName,0,0,ParentItem);
else
LocalItem = pTreeToFill->InsertItem(strName,1,1,ParentItem);

Result = pOccu->get_SubOccurrences(&pOcEn);
CComQIPtr pOccs(pOcEn);

Result = FillTree(LocalItem, pTreeToFill, pOccs);
}
return Result;
}

Answering to my myself, I found one way by try/error method 🙂 Here it is...

CComPtr pOccu

IDispatch* pIDisp=NULL;
pOccu->GetDefinition()->get_Document(&pIDisp);
DocumentPtr pDocFromOcc(pIDisp);
CString strFullFileName = (LPCSTR)pDocFromOcc->GetFullFileName();

As I'm relatively new to COM programmnig especially with C++ I would
appreciate any comments you might have. Is this the 'right' way of doing
this?
