Flowcharting of Visual Basic Project Files

Dear all,

I'm looking for software that would flowchart my visual basic files:
relationships between forms, called dlls etc... I'm not interested in
flowcharting the source code. I found one program that can do this in
Project Analyzer.
However, I was looking for a cheaper alternative. It seems that Visio
and UML can achieve something similar, but I have been unsuccessful so

If you guys have any good ides let me know.

Thank you,
