[mapguide-users] Add point to map

[Kenneth Skovhede, GEOGRAF A/S]

If I understand correctly, you want to draw features on the map.
This is usually called redline or redlining, so searching for that 
should yield a few examples.

The process is this:
1) Create a FeatureSource (or re-use one)
2) Insert geometry into FeatureSource (point in your case)
3) Create a LayerDefinition that describes how to display the geometry, 
and references the FeatureSource.
4) Insert the layer in the runtime map
5) Refresh the client

I have written about this numerous times, so you should be able to find 
good examples in the archives.
Also, all steps are performed with the Buffer code in the AJAX viewer.
Simply open buffer.(aspx|jsp|php) and you can see each step in your 
favored language.
