The auto-generated part of files start with "Begin VB.Form" and end with "End" (first thing on the line). The "End" keyword may appear inside the auto-generated part, but not at the beginning of the line.

I think we can take help of regular expressions.

import re

rx = re.compile('^Begin VB.Form.*^End\n', re.DOTALL|re.MULTILINE)

def count(filename)
    text = open(filename).read()
    return rx.sub('', text).count('\n')
