Hi,

We have a project that was originally developed in VC++ 6.0.  It had a dsw,
a dsp, and a number of c, cpp, and h files.

We upgraded to .NET (Microsoft Development Environment 2003 7.1.3088) and
opened the DSP file. It was converted into a vcproj and a sln.  After
making necessary changes we got it to compile and link.

Then it turned out we needed to modify some preprocessor definitions.  In
VC++ 6 we had set them in Project/Settings/C-C++/Preprocessor Definitions.  
Those settings carried over into .NET in the Project/Myproj Properties/C-
C++/Preprocessor/Preprocessor Definitions.

So we modified them there, recompiled, and found that our changes had no
effect.  The new preprocessor definitions showed up as undefined, and old
preprocessor definitions that we had removed showed up as defined.  We
closed MSDE and re-opened it; our changes still showed up in the
Preprocessor Definitions section but had no effect on the code.

We can make other changes to the project properties and they do take effect
-- the preprocessor definitions are the only ones that don't take.

Is there someplace else to set up C++ preprocessor definitions in Visual
Studio .NET?
