Well, that won't help you much... You will see a list of functions, but to call them, you also need to know their signatures, and that's the problem as far as you only have a dll. You either need to have a header file (C/C++ program) or some kind of a document (maybe help file) that describes the functions in that dll.

This is not a function, it's a dialog resource definition.
