New Sample: Application-Defined System Variables

[Anonymous]

   http://www.caddzone.com/CustomSystemVariableExample.zip

Abstract:

As of AutoCAD 2010, it has been possible to add new system variables to

AutoCAD, that are both defined and managed by ObjectARX extensions

(managed or native).

Application-defined system variables behave just like AutoCAD's

own 'built-in' system variables.

The sample project at the above link shows how to implement your own

application-defined system variables.

Thank you Tony.

Interesting concept with a lot of potential.

... and a generous license.

also excellent study material.

Hope this is a tease to book or guide you are putting together

Well, it woudln't make sense to just throw it out there if that were the case, as I haven't really left much out.

Sorry, what I meant was the example was great. It had a good explantion and good design pattern,reusable, easy to matain etc...... all of the things you try to accomplish writing code.

I was implying it would great to have a book that covered many topics in the API like your example.

Sorry about that.

I didn't bother checking the 2010 API, and just learned that the APIs

required to implement app-defined sysvars is not avaialble in 2010.

A revised and expanded version of the sample has been posted at

the same URL, which makes that clear.
