hi, You could use an obfuscator (there are some good commercial ones, try google), but i don't see the point.
Either is the source so bad you don't want anyone to see it? or are you scared that someone steals it?
If someone can read the code, probably someone can write it as well.
If you see an an application, you can probably build your own version. I don't see any point in hiding code other than hiding your mistakes from the world.
