In VC++ 2008 Express, I open a new "Hello World" project (CLR Console Application). If I right-click the project in the solution explorer, and select "properties", I get a "... Property Pages" window which shows a line entry for: Configuration Properties / C,C++ / General / Additional Include Directories. It also has a line entry for: Configuration Properties / Resources / General / Additional Include Directories. (Both lines are empty).
If I go to the main menu, and select: Tools / Options / Projects and Solutions / VC++ Directories, and select "Show Directories for Include Files", I see another multiline entry. This one lists many directories, such as:
Why so many places to specifiy include directories? Could I place my list of include directories in any and/or all of those places? And secondly, where in the IDE can I found out what the environment variables $(VCInstallDir) etc.... are set to? (Without going out to a command window and checking $PATH).
Thanks ahead of time :-)
