[mapguide-users] Re: Is it Possible to set Feature Label for a layer dynamically

[Kenneth Skovhede, GEOGRAF A/S]

Yes, you should change the <Text> node for the <Label> element.
The xml format is not as documented as it should be, but there are some 
xsd files
in the MapGuide folder that explains the technical format.

To save the resource, simply call SetResourceContent,
much in the same way that you called GetResourceContent to
get the xml.

6) is layer.SetLayerDefinition(...) (MgLayer::SetLayerDefinition)
7) map.Save(...) (MgMap::Save)
8) GetMap().Refresh()
