COM API and multiple versions
When I create a COM program in VB.NET and add a reference to the Bricscad type library, I am required to select a library for only one version. The program then runs only on the version that matches the reference added. This can be a problem when some users are using older versions of Bricscad. I have attempted to add multiple Bricscad references but Visual Studio does not allow that. Is there a way to work around this other than creating a program version for each Bricscad version being used?

Hi James,
I think you do have to create multiple executables. I create multiple Projects within one Solution - each project has a target eg Bricscad 10, Bricscad 11, AutoCAD 2010 etc. All my source code is in one of these projects only. Then I add those source files to the other projects 'AS LINK'. So there's only one set of source code files.
Installer: In Program Files under my program's folder I create multiple sub folders for these different program executables. My toolbar commands launch 'someprogram.exe' without any path given. I set the search path variable in CAD to include the correct subfolder. So there's only one set of toolbars. There may be other approaches, but that's what I do!

you can also try using late binding techniques

Damian: Thank you for your response. I was hoping to avoid multiple executables but your method sounds good.
Daniel: I have never used late binding but will do some research. Thank you.
