How to include a .DLL?

If you don't want to provide the source, how can it be open source?

Most of it will be open source but I don't want to open source small part of it dealing with USB.So basically I want to release the source code but not one of include files.

Forget about that...
First you can easily dissemble hex file, and get that ASM code. Second, how PIC will execute commands if they are encrypted. Any way you must write original source code to FLASH if you want to execute it.
So even if code is loaded in flash encrypted, and then decrypt in pic and wrote to FLASH again, just run your code in some simulator, and look FLASH content...
I don't want to be rude, but open source with hidden source is plain stupid...

I don't want to be rude either but pedja089 realy does have a point. It's either open sorce or its not (like being a little bit dead)

I don't mind if they dissemble the hex.I just don't want it to be too easy to simply read the code.As far as I can call a function in Bootloader then I am fine.I am a bit new to bootloader but can I upload two hex files to MCU? or second hex should be done through bootloader?

There is some programmers that would you probably allow you to load two hex...
I always put precompiled bootloader at end of main app and every thing i need for production is in one HEX.
