以下代碼演示瞭如何加載指定tab文件

int CHtGisClientView::LoadCustomLayers(char *LayerDirPath)
{

    CMapXLayerInfo layerInfo ;

//    CMapXFields mapFields;
    
    CStringArray tabFileList ;

    try{

        layerInfo.CreateDispatch( layerInfo.GetClsid() );
//        mapFields.CreateDispatch( mapFields.GetClsid());
//
//        mapFields.AddStringField("FID",254);                 
//
//        COleVariant vFields;
//        vFields.vt=VT_DISPATCH;
//        vFields.pdispVal=mapFields;
//         vFields.pdispVal->AddRef();

        GetFilesOfPath( LayerDirPath , tabFileList ) ;

        CString tabFileName , tabFileTitle ;

        for ( int i = 0 ; i < tabFileList.GetSize() ; i++ ) {
            
            tabFileName = tabFileList.GetAt( i ) ;
            tabFileTitle = GetFileTitleFromFileName( tabFileName , FALSE );

            layerInfo.SetType( miLayerInfoTypeTab ) ;
            layerInfo.AddParameter("Filespec" , COleVariant(tabFileName) );
            layerInfo.AddParameter("Name" , COleVariant(tabFileTitle)  );
//            layerInfo.AddParameter("Fields", vFields );

            m_ctrlMapX.GetLayers().Add(layerInfo);

        }


        return R_OK ;
    }
    catch(COleDispatchException* e) {
        e->ReportError();
        e->Delete();
    } catch(COleException* e) {
        e->ReportError();
        e->Delete();
    }    
    return  R_DEFAULT ;

}
