Which type of file, OCX or Dll, is more secure in terms of cracking the file
and changing the functions and/or procedures the file contains?

Thanks!

They're all equally hackable. As far as actually changing the functions...
if the hacker's capable of that level of disassemby, might as well give them
the source because it'll take far longer to protect against that skill level
than it will for that guy to crack your code.

Neither has a 'security' advantage over the other, if a potential attacker
has physical access to the file or its environment (OS).

In fact no 'program' can do anything to totally protect itself - it is
completely dependent on its environment to provide these services.

There is no elementary difference between an OCX and an ActiveX DLL,
especially there is >>no<< difference in the type of binary code.
Simplifying it one could say: An OCX is an ActiveX DLL with the filename
extension '.ocx', and an ActiveX DLL is an OCX with the filename extension
'.dll'.

No difference whatsoever because both (as far as created in VB) are
essentially the same (meaning both ActiveX). Sure, in development there are
differences, but as far as a compiled file, virtually no differences.
