move most of the code or critical parts of the code out of excel and compile
it (would probably require extensive rewrites) . Within Excel, no.

Hi

Is it possible to secure the VBA in an excel project, so that it cannot be
openned, even with third party software, such as that from Elcomsoft? I
know
how to password protect the VBA, using the project properties, but have
heard that there is software that can either crack this password, or use a
"backdoor" to gain access to the source code. Is there anything that can
be
done to prevent uch software allowing access to the source code?

Many thanks in advance for help,

Dave
