var landmark = new Service("Service.Landmarks", "IDataSource");

                // Get the lists of IDs and landmark information to Arrays
                idList.push(outputEntry.id);

        var errorId = outParams.ErrorCode;
        text_txt.text = "Error while listing: "+errorId;
    };
};

export_mc.onPress = function() {
 
    // Define input parameters
    var inputData = {
        IdList:idList, DestinationFile:"c:\\Data\\Others\\landmarks.lmx", 
        MimeType:"application/vnd.nokia.landmarkcollection+xml"
        };
    var inParams = {Type:"Landmark", Data:inputData};
 
    // Define result value
    var outParams = landmark.Export(inParams);
    if(idList[0]) {
        if (outParams.ErrorCode == 0) {
            text_txt.text = "All landmarks exported to file";
        } else {
            var errorId2 = outParams.ErrorCode;
            text_txt.text = "Error while exporting: "+errorId2;
        };
    } else {
        text_txt.text = "No landmarks listed!" +
            "Press the List button to list all the landmarks to the input.";
    };
};

When the List button is pressed, all landmarks are displayed. You can export listed landmarks by pressing the Export button.
