>When building an application in the project manager it is including some forms and class libraries that are not in the project but are in another project. I have traced each control in every form to see if the class/base class is referencing the control from the other project and I have also check the class libraries as well to see if they are referencing the other project's classes. Is there a way to get the project to log where each control that is being included is coming from. I've looked at the project hook in the help but I don't see anything there.

Just a guess, but

If the parent project has a call reference to a child project, and the child project has a program with the same name as the project. Then you must build the child project first, and then add the built application (app,etc) to the parent project. When the parent project is built, it will see the child application and will not attempt to include the file reference in it. Unless the parent project files reference them explicitly.
