I am currently asked to edit an existing application which uses an old dll that may have been created using Microsoft Visual C++.
I initially thought that it could have been a dll created in Visual Basic so I used a Visual Basic Decompiler to decompile it but it says that it didn't detect Visual Basic Runtime Environment on it. Then I open the dll on the notepad and as I browse through the "un-understandable" text, I saw "Microsoft Visual C++ Runtime Library". That is why i think this old dll is created from a Visual C++. Now the point here is the old dll's code is already gone therefore I can't edit it anymore. I was thinking if there are ways to get the source code back from the old dll.
