Hi José,

Have them sign a contract that specifies what they are allowed to do with the code and gives you the chance to discover misuse. There's no way to protect a single VCX file against decompilation.

You might be able compile the class into a COM DLL and only ship the DLL without source. Then you could use ReFox or similar tools to protect the DLL to a certain degree. It's still not 100% secure, but raises the bar. However, this only works if the classes are strictly non-visual, the project permits to deploy additional DLLs and the other developers don't have to subclass you classes.
