Hi,
 I'd like to alter the default list of directories that VS.NET 2003
uses when building C++. I'd like to do this using a script or program.
Documentation on automation was promising (the DTE.Properties help) --
but notes that only the info listed on that page can be altered... and
it doesn't list the include path. What is the proper way to go about
this?

 In a bit more detail. One can add a directory to the default
multi-project list of include path searches in VS.NET by going to
Tools->Options->Projects->VC++ Directories and then selecting "Include
Files" and adding the directory. I'd like to do exactly this, but under
scriopt/program control.

 Burried in the registry are a list of the include paths
(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\7.1\VC\VC_OBJECTS_PLATFORM_INFO\Win32\Directories)
but altering things there doesn't change anything when the environment
is restarted. I also looked in AppData directory and failed to find
anything obvious (a quick text search of the files there).

 At that point I hit upon the idea of using automation to do it. After
all, if I did that, perhaps I'd even survive the upgrade to 2005. Alas,
I can't find the entrypoint to alter that information. The above
referenced page from MSDN documentation doesn't menting the
projects->include files path.

 Guidence most appricated!

 Cheers,
   Gordon.
