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

[Kenneth Skovhede, GEOGRAF A/S]

You are correct about the new MgMap(...) call. My mistake.
So it becomes:
MgMap map = new MgMap(siteConnection);
map.Open(mapname);
map.GetLayers().GetItem(0).SetLegend("Changed");
map.Save(resourceSrvc, mapname);

Yes, I meant the Refresh() call.

If nothing happens, either you are not calling the correct frame, or the 
map has not been saved.
Try to use FireFox and the FireBug plugin to see where the calls go.

Regard, Kenneth Skovhede, GEOGRAF A/S
