Hi,
Is it possible to change the references in a project by using
preprocessor directives?

Thanks,
Bob

It is not at all different. I have no idea where that thread is, I
thought that google lost it. When I look under my profile there is
nothing and when I search for preprocessor directives I get nothing.
If you could point me to the thread I'm sure it would answer the
question.

Thanks,
Bob

I think you can do something like the below for referencing the
namespace.

#if SYMBOL
using System.Collections;
#endif

however referencing dll is a compile time option not included in the
code.

It would be your choice to include a perticular dll in /r option or
not.

-Cnu

Thanks for your response. The problem I am having is with different
versions of Excel that have same name so I want to be able to have one
build for release 11 and another for release 12. They have the same
"using" name so the first option won't work. I don't follow your
second suggestion.

Thanks very much! What is a better news server?

Thanks. This is a dumb question but where is the build file in a
Visual Studio project?

Look for a file called .csproj.
