DLL  

I asked about this in another thread but I didn't explain why I need to know about this. I am working on fixing an app that was created by a person that is no longer here. Since I was the one that worked closely with him, they felt I should be the one to fix the app. He taught me about going in to the DLL or the registry to fix things in the code. I just cant remember how to get to the DLL or the registry. This app is a very important function in my work cell and I need to get this fixed and fast.

I'm not quite sure what you mean by the DLL. Are you referring to a .dll file as in a Dynamic Link Library? Which is a compiled file that usually expands the functionality of any executable binary file that calls it, as a dependency for example. Also when you said the registry are you referring to the Windows registry or something different?

DLL files can't just be open in a text edited and modified BTW, they are in and of themselves binary files also.....just not executable ones, although there are things like rundll32 that can launch functionality stored in shared .dll files.
