Example

This example shows how to obtain (the GetEnumSectionContribs function) and use (the ShowSectionContribs function) the IDiaEnumSectionContribs interface. For a more complete example of using section contributions, see the IDiaSectionContrib interface.

  
      IDiaEnumSectionContribs* GetEnumSectionContribs(IDiaSession *pSession)  
{  
    IDiaEnumSectionContribs* pUnknown    = NULL;  
    REFIID                   iid         = __uuidof(IDiaEnumSectionContribs);  
    IDiaEnumTables*          pEnumTables = NULL;  
    IDiaTable*               pTable      = NULL;  
    ULONG                    celt        = 0;  
  
    if (pSession->getEnumTables(&pEnumTables) != S_OK)  
    {  
        wprintf(L"ERROR - GetTable() getEnumTables\n");  
        return NULL;  
    }  
    while (pEnumTables->Next(1, &pTable, &celt) == S_OK && celt == 1)  
    {  
        // There is only one table that matches the given iid  
        HRESULT hr = pTable->QueryInterface(iid, (void**)&pUnknown);  
        pTable->Release();  
        if (hr == S_OK)  
        {  
            break;  
        }  
    }

    pEnumSectionContribs = GetEnumSectionContribs(pSession);  
    if (pSectionContrib != NULL)  
    {  
        IDiaSectionContrib* pSectionContrib;  
        ULONG celt = 0;  
  
        while(pEnumSectionContribs->Next(1, &pSectionContrib, &celt) == S_OK &&  
              celt == 1)  
        {  
            PrintSectionContrib(pSectionContrib, pSession);

        }  
        pSectionContrib->Release();   
    }
