Visual C++ 6.0
Additional Include Directories tell Visual Assist where to find header files for 3rd-party libraries--header files that Visual Assist parses infrequently. Because there is no interface in Microsoft Visual C++ 6.0 to specify the directories, give direction to Visual Assist by manually editing your project file.
1) Add the following line after "#Begin Project" to make Visual C++ 6.0 accept the modified .dsp file:
CPP=cl.exe
2) Add the following line at the end of a #PROP section to include the dir1 and dir2 directories:
# ADD CPP /I "dir1" /I "dir2"
