David C# is probably the quick solution. These classes, generated by XSD or XDS2Code (much nicer, as an add-in with lots of control), will be hand-tuned and then can be compiled to a DLL - so the VB people can use that. The application it will be used in was originally (2004 to 2007) written in VB.NET with framework 2.0 - I had forgotten the rehashed version of the application will be written in C# anyway. The XSD schemas are set in stone (and include many includes) - ISO FGDC ANZLIC etc - so we leave the xml alone. Generated classes for the UI / data maintenance have more flexibility.
Thanks - you got me over that mental block. (and it would be clumsy to code that in VB) ________________________________ Ian Thomas Victoria Park, Western Australia -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of David Richards Sent: Monday, August 06, 2012 6:51 AM To: ozDotNet Subject: Re: Enum problem - case-sensitivity Ian, I just got into the office and confirmed the enumeration would work in c#. eg: enum blah {y, Y, n, N} is fine. I just realised the reference to a default enumeration value was a separate question, sorry. I'm not aware of this option being available in xml but the first value in an enumeration is, unless specified otherwise, set to 0. So you could possibly include "Unknown" or "NotSet" as your first value. The result would be: enum blah { Unknown, y, Y, n, N } I'm assuming I understood your question correctly :) David "If we can hit that bullseye, the rest of the dominoes will fall like a house of cards... checkmate!" -Zapp Brannigan, Futurama On 6 August 2012 07:13, David Richards <[email protected]> wrote: > Ian, use c#.
