Yeah I've been there and done that :) The company I worked for is still using an (shudder) access database system that I developed 4+ years ago. I got no honours or recognition for it other than the knowledge that I had done a good job (well at the time...) and produced a useful tool. My advice- release the code, update your resume and find a job with someone who *will* appreciate you.

All the better on your resume if the product *is* so good they sell it- imagine going into an interview and being able to say to a potential employer that you saw a problem within your present company, that on your own initiative you solved the problem *and* your solution was so good that the company was able to turn it into sales revenue as well.

Do what you love doing. Do it well. Let the accolades and the money take care of itself.
