Hi, I'm not sure what programming language dlls are, so I just posted this here.

What program can I use to open up dlls and modify the code within?

Thanks.

DLLs can be made in a plethora of languages, Delphi, C++, C, Visual Basic, and even FORTRAN I believe.

You don't really 'modify' a DLL like you would a .jpg file, it's an actual file with code, so the best you'll get is a disassembly reading. They're very important parts of Windows, so it's advised that you try not to mess with them if you don't exactly know what you're doing.

I know what I'm modifying; it's a dll that I dled from a forum.

I opened it with Visual Studios 2005, and it doesn't really display codes... this is what it displays:

It's just displaying information over the file, not the file itself. You have the ability to specify a lot of information over stuff like that when it's produced and whatnot - that's what you're being shown.

If it's just a resource DLL with things like Icons and whatever, you can use a program like Resource Hacker, if you actually want to disassemble it, use a program like OllyDBG or IDA Pro.
