Call .DLL file from MS Access

I need a .DLL file or some sort of encrypted file or something similar that can to be called or referenced from MS Access I have a monster size MS Access system that is a complete business, stock and sales management system with a comprehensive end of day reconciliation function. I do have a long password in the VBA code but it’s not secure enough And because of the systems size I cannot make it a .mde file to keep hacker out. I need to hide these functions en sequence of functions from potential hackers. See [login to view URL] for the type of functions that needs to be executed I would also need some guidance as to how the dll file is called or referenced to get to the functions working. I need to edit the dll file as the system grows and I need to add functions. ## Deliverables * * *This broadcast message was sent to all bidders on Monday Nov 22, 2010 5:50:49 PM: Hi guys It seems like most of you do not really understand what the requirements are. Please look at the attached diagram for more details I only need to hide critical modules and functions and thought .ddl is the way to go but if you have better idea please let me know.
