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

[Antonis Mihalas]

As far as I know, this is not possible, because 
MgMap map = new MgMap(resourceSrvc); it takes as argument a siteConnection...


When you say refresh the client you mean just to write one line *.js?
without importing anything?

I'm asking, cause parent.parent.Refresh();
              or
parent.mapFrame.Refresh();

doesn't do anything...

The viewer overwrites the runtime map on startup, so if you run this 
before starting the viewer, your changes will be lost.
You should not create a new runtime map, but open the one the viewer 
creates for you, modify it, save it, and refresh the client.
I belive the correct sequence would be:
MgMap map = new MgMap(resourceSrvc);
map.Open(mapName):

The viewer takes a string like:
"Library://Folder/MapName.MapDefinition"
and uses the map name:
"Folder/MapName"

You must use the same name in your code, or you won't get to the runtime 
map.

If you want the layer to show when the map loads, have a look at this:
http://trac.osgeo.org/mapguide/wiki/maestro/MaestroAPI/samples/AddInitialLayer

You can perform the same actions without the MaestroAPI if you like, but 
you have to deal with the xml in raw form.
