In what way is this question different from the last time you asked it?

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.Collecti ons;
#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.

I have no idea why the thread doesn't appear on Google. I'd say they
probably did lose it. The thread is on my own news server though and
probably on other more-reliable ones. You might try an alternate news
server; Google is definitely not the most reliable around.

In the meantime, see below for the two replies to your original question.

I'm not sure. I don't think so, but haven't explored that fully. But,
you should be able to use the configuration manager to create a build
configuration where a particular preprocessor symbol is set
appropriately and the associated library is referenced. Both the symbol
and the reference would be dependent on the build configuration, rather
than making the reference dependent on the symbol. But that may be
close enough to what you want.

Not based on preprocessor symbols as far as I'm aware, but if you tweak
the build file you can change references based on build configurations
(which can also change the preprocessor symbols of course). We do this
for MiscUtil. For instance, we've got sections like this:
>
<ItemGroup Condition=" '$(Configuratio n)' != 'Release 2.0' ">
<Reference Include="System .Core">
<RequiredTarget Framework>3.5</RequiredTargetF ramework>
</Reference>
<Reference Include="System .Xml.Linq">
<RequiredTarget Framework>3.5</RequiredTargetF ramework>
</Reference>
</ItemGroup>

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

Look for a file called .csproj.

Difficult to say for sure, because it depends on what you have access to.
But there's a free server at http://aioe.org/ For this particular
newsgroup, you can use Microsoft's public server, which can be reached
with the name msnews.microsof t.com or news.microsoft. com. There are paid
services, including Supernews (not great, but better than Google), and the
one that my own ISP uses, Giganews (that is, I don't pay them directly,
but my ISP outsources to them so that's what I wind up using anyway).

If you only need access to the Microsoft "microsoft.publ ic..." hierarchy,
then I'd say Microsoft's server would be the best bet. You appear to be
using Vista, so as a news reader you might use the Windows Mail program
(which used to be Outlook Express). Or, since you're a Firefox user, you
might prefer Thunderbird. Other alternatives include 40tude, FortÃ© Agent,
and Opera.
