Hi
I have to edit the geometry of existing line shapes. Is this really possible and how can I manage it?
I don't want to create an empty inMemoryLayer and than add shapes by listing coodinate queues in the source code.
A good example (Visual Basic) of this will really help us. The examples in the webeditionsample doesn't unfortunately contain no hints on this action.
Any advise on how to edit existing layers?

Hi Ben,
thanks for the good example. I think this will answer my question. Is it possible to get the example also in Visual Basic Code?
Thank you much for Your help.

Hi Ben,
thank You for the rigth example. We have a last problem with the code record
--> Dim features As Collection(Of Feature) = Map1.EditOverlay.Features
It doesn't work because the string 'Feature' in the brackets is marked by the VB Editor as error.
Thank You much for Your help.

Joerg,
That’s because you didn’t imports the System.Collections.ObjectModel namespace. By default using VB.net, there is a collection but that’s not a general Collection(Of T).
Thanks,
Ben
Hi Ben,
wonderfull! It finally works. Now we intend to edit a PostgresLayer. Is this also possible?
Thank you very much for Your help.
With best regards
Joerg
Joerg,
Yes, we support the transaction in Postgre. Go ahead and have a try, the codes should be very similar as the ShapeFile one.
Thanks,
Ben
