Protecting VBA code.

[cheeseed]

I have written some VBA code that I am thinking about selling. How can I protect my work? The way I see it there's nothing stopping someone from just copying the source file from one PC to another instead of buying additional copies from me.

Any ideas?

8) You can do a couple of thing to stop others from pritating your code..

1/ Compile your code into a DLL...you will need VB for this and the code itself will have to transfered to it...you'll have call autocad from the application.

2/ You can also LOCK your application, so that user would need an authorisation code to unlock it...Have a read of this link to get more info on this.
