Specifically, you're telling grep to only look in directories which have
'.vb' in their name.

You should always use the -print0/-0 syntax, just in case. And I'd find
it a bit more readable as:
find . -name '*.vb' -print0 | xargs -0 grep -i path32

Alternatively, you could use zsh as your shell, and just use:
grep -i path32 **/*.vb*
