I planed to create a engineering application program by using excel macros.
However, I realise that someone could open the code of the program, although
I could have protect the sheet. I wonder, is there any possity to compile the
codes as an dll or exe file.

You can't compile VBA code into a DLL or EXE file. If you have
VB6 or the Developers Edition of Excel, you can write a COM
Add-In, which is an ActiveX DLL with some special code for
startup and shutdown.
