Hi all and thanks for reading,

I'm trying to figure it out how the developement licensing works.

Can I use VBA with the 9.3 version for free?, do I need a license?
If I have to use Visual Studio to extend ArcMap, what kind of license do I need, the EDN subscription?, if I buy the annual EDN subscription, I'll be licensed to develop in any ESRI platform (Server, Mobile and Desktop)?.

Thank you very much!
