    CString strPrint;

    _variant_t pVariantArray = dsDoc->GetExternalReferences();
    if( V_VT( &pVariantArray ) != VT_EMPTY )
    {
        IExternalReferencePtr *ExtRef = NULL;
        int countOfExtRef = 0;
        TypeConverter::convertVariantArrayToPtrArray<IExternalReferencePtr, IExternalReference>( pVariantArray, ExtRef, countOfExtRef );

        strPrint.Format( L"External references (%d):\r\n", countOfExtRef );
        fileOutput.WriteString( strPrint );

        if( ExtRef && countOfExtRef > 0)
        {                           
            for( int i = 0; i < countOfExtRef; ++i )
            {
                IBlockDefinitionPtr blkDefs = ExtRef[i]->GetBlockDefinition();               
                if( !blkDefs )
                    continue;

                bstr_t BLockName= ExtRef[i]->GetName();
                strPrint.Format( L"Block definition name: %s\r\n", BLockName.operator const wchar_t*() );
                fileOutput.WriteString( strPrint );              
            }
            delete[] ExtRef;
        }
