I'm making a script using AutoHotkey programming language but I want to expand its abilities by calling different types of .DLL functions. The problem is that other than most of the known windows standard .DLLs I cannot be aware of any other .DLL list of functions and their input demands. Is there any website that can provide me with information about what I'm looking for? PS. Please avoid suggesting me to try use the "dumpbin.exe /export .." command on the visual studio command prompt - doesn't work for me for some reason - plus It's best to know first what suits me for the job before downloading it. Thank you.
