Is there a way to estimate how big a visual basic project will be in kb?

I have heard of automated ways (as shown in the link h++p://www.vbexplorer.com/VBExplorer/tips/src38.asp) but I am looking for a manual way to do this for my A level project. I need to show i can estimate roughly how big my project will be and explain how i did this.

E.g. A project with 13 forms with 4 command buttons each, 2 labels with short headers like "View Details", several text boxes and two modules with 100 words in them.

Any ideas?
