[mapguide-users] Nothing is working or what I'm doing wrong?

Whatever I try to do it's just not working.

Add a new layer?
The layer is added but never shown

Add a point? Nothing

Add a new group?
The Group is added but never shown

So, I simple tried to change the LegendLabel of an existing layer.
Nothing happened again...

If anyone can tell me what I am doing wrong I would appreciate it.

Code follows:

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using OSGeo.MapGuide;
using System.Xml;
using System.IO;
using System.Text;

public partial class _Default : System.Web.UI.Page
    public string sessionId;
    public string webLayout;
    public MgLayer tmpLayer;
    protected System.Web.UI.HtmlControls.HtmlGenericControl Frame1;

    protected void Page_Load(object sender, EventArgs e)
        string physicalPath = @"C:\Program



            //Associate a session ID with the MgSiteConnection Object
            MgUserInformation userInfo_new = new

            MgSiteConnection siteConnection = new MgSiteConnection();


            // Get an instance of the required service(s)
            MgResourceService resourceSrvc =
            MgFeatureService featureSrvc =

            MgMap map = new MgMap(siteConnection);

            webLayout =

            MgResourceIdentifier resId = new
MgResourceIdentifier("Library://GoSpatial/Maps/Italy Map.MapDefinition");

            String mapName = resId.GetName();

            MgResourceIdentifier mapStateId = new
MgResourceIdentifier("Session:" + sessionId + "//" + mapName + "." +

            createSaveOpen(map, resourceSrvc, resId, mapName, mapStateId);

            MgLayerBase firstLayer = map.GetLayers().GetItem(0);

            map.Save(resourceSrvc, mapStateId);
        catch (Exception ex)
            throw (ex);

Thx in advanced!

PS I have never but never in my life try to do something and in 2 weeks not
shown even a small improvement...
