Automated Development of Projects with Custom Build Steps

We are trying to build a project made up from eight hundred individual source files each of which requires a custom build step, and because of that needs it's dependencies specifying explicitly.


Does any body know how to do this?


We are having trouble assosiating the collection of documents objects of the application with the projects collection.


Also the help does not tell us of any method for adding dependencies to a custom build step from a C++ add-in, or VBScript.
