[mapguide-users] Modify layout with anonymous user

[Kenneth Skovhede, GEOGRAF A/S]

Something like this would do it with MaestroAPI (untested):

            MaestroAPI.ServerConnectionI con; //Needs initialization

            //Read the current resources
            MaestroAPI.WebLayout layout = con.GetWebLayout("???.WebLayout");
            MaestroAPI.MapDefinition map = 
con.GetMapDefinition(layout.Map.ResourceId);

            //Create the temp layer
            MaestroAPI.MapLayerType layer = new 
OSGeo.MapGuide.MaestroAPI.MapLayerType();
            layer.ResourceId = "???.LayerDefinition";
            layer.Name = "Temporary layer";

            //Add it to the map
            map.Layers.Add(layer);

            //Generate a session based temporary id (will become 
Session:<sessionid>//Random Map Identifier.MapDefinition)
            string tempMapId = new MaestroAPI.ResourceIdentifier("Random 
Map Identifier", MaestroAPI.ResourceTypes.MapDefinition, con.SessionID);
           
            //Save the modified map in the session repo
            con.SaveResourceAs(map, tempMapId);

            //Modify the layout to point at the temp map
            layout.Map.ResourceId = tempMapId;

            //Generate a session based temporary id, and save the 
modified layout (will become Session:<sessionid>//Random WebLayot 
Identifier.WebLayout)
            string tempLayoutId = new 
MaestroAPI.ResourceIdentifier("Random WebLayout Identifier", 
MaestroAPI.ResourceTypes.WebLayout, con.SessionID);
            con.SaveResourceAs(layout, tempLayoutId);

            //Open the viewer with the modified weblayout, that uses the 
modified map
            Response.Redirect("/mapguide/mapviewerajax/?session=" + 
Server.UrlEncode(con.SessionID) + "&layout=" + 
Server.UrlEncode(tempLayoutId));

You can rewrite the property access with the corresponding xml changes,
and the GetResource/SaveResource with the corresponding function calls 
to the
MapGuide API, if you don't want to use Maestro.

Instead of the "Random ... Identifier" strings, you should use 
Guid.NewGuid().ToString().
