Code security in VB
I have written an add-in using VBA in excel that I want to sell. It
began as some programs to help me do things I do every day, but
eventually grew enough and is useful enough that I think there will be
some interest in it.
However I am concerned about the security of my source code when
distributing the add-in. From searching on the internet I have found
at least one program that promises to unlock any protection in VBA.
While I know this is illegal, it is easy enough that I worry that some
people might do it.
Is there any way for me to encrypt or otherwise protect my source code
in the addin? The VBA SDK 6.3 says it has improved password
protection, does this meet my needs? I do not want to have to
re-write much of my code.
