[mapguide-users] Add geometry to SHP

[Dejan Gregor]

Hello Simon,

thank you for the code sample! Did you need to develop any additional tools
for adding features (e.g. edit tool)?

I am not a developer, but would really like to test this on adding new
polygons (SHP) through the MGOS 2.x web client.

Thanks, I will try it out.

Dejan
