Hi,

I have to develop an application using VBA/EXCEL and I want to protect
as
much as possible the code. Macros are in the spreadsheet itself (just
a few like auto_open) and in a separate xla file.

Xla as far as I know can be open even if protected. can you please
advice any other way to protect it? I read somewhere that an option is
to create an .ocx. is this true? if so, does anyone know any good
reference on how to convert from XLA to OCX?

Thanks in advance
