i work for a non-IT company.i made a s/w solution using vb6 basically as a hobby.now the boss is pressurising me to part with the source code as maybe he sees marketing potential in that.(maybe he thinks of changing the name of our company on the software and selling it to others or something like that) .since i am under a job contract, i will have to part with the source code but can anybody suggest ways that he is unable to use it.any suggestions are welcome.something like some hidden code which makes the program go bad after some date or anything like that.
