This code will remove comments, indentations and blank lines. It will need a
reference to the VBE extensiblity,
Microsoft Visual Basic for Applications Extensibility 5.x. You could put it
in an add-in.

To scramble all Procedure names shouldn't be too difficult either.

Hi,
I have an excel VBA application that I'm considering to sell at some
point.

As a deterant to any unauthorized usage, I was wondering if it's possible
through VBA to completely remove all comments and rename all the routines
and
functions in all modules and forms with unrecogizable names so that the
code
would work yet be vertutally impossible to understand.

Thanks for any help!
