[mapguide-users] Add geometry to SHP

[Dejan Gregor]

Dear Fabio,

you are saying that with the exsiting FDO it is possible to add geometry to
a SHP?

Do you have a sample code for MGOS 2.x also for the interface or maybe a
whole project/sln? I am not a programmer, but would like just to test this
functionality in MapGuide.

Best regards,
Dejan
