The external dependencies is automatically created by the compiler; it drops any header files that aren't listed in another section in there. Also note that the External Depencies aren't saved in the .dsp file afaik, so they don't really belong to the project at all.
So if you want to add files to your project, always add it into one of the "proper" sections. External Dependencies is just there so that you don't accidently forget about a header file you depend on. Actually, you don't have to add header files to the project at all. The #include is all that matters. However, it's nice to have the headers in the source files list for easy browsing. Additionally, some tips features of the editor (such as member lists) only work when the header file is added to the project. cu, Prefect _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
