[mapguide-users] switching to Maestro 5 API

[mika at digikartta.net]

Thanks Jackie,
that helped.

Another question relating to the same field.

Constructing features and inserting them into feature source. I'll try 
to cut irrelevant part out of this. I can't figure out how to do this. I 
guess the actual insert would go like this.

IInsertFeatures ins = 
(IInsertFeatures)conn.CreateCommand((int)CommandType.InsertFeature);
                                 ins.FeatureSourceId = "xxx";
                                 ins.ClassName = "yyy";
                                 ins.Execute();

But how would I "bind" and construct the "propertycollection" for that? 
Any examples?

This is a snippet from my old method.

routes)
     {
         int inserted = 0;

                 MgStringProperty type = new MgStringProperty("type",

                 routeCol.Add(geom);

                 string fclassName = 
"schema_routelines:dim_routepoints";
                 MgInsertFeatures insertFeatures = new 
MgInsertFeatures(fclassName, routeCol);
                 commands.Add(insertFeatures);
             }
             else if (route.geometry.type == "LineString")
             {

             }
         }
         if (commands.Count > 0)
         {
             insertedFeatures = mfs.UpdateFeatures(mri, commands, 
false);
             inserted = insertedFeatures.Count;
         }
         return inserted;
     }
