I have an old DLL that stopped working (log2vis.dll) and I want to look inside it to see what objects it uses.
The DLL was written in C++ (not .NET). Is there a tool that will decompile/disassemble C++ files?
This question is related to
c++
dll
decompiling
This might be impossible or at least very hard. The DLL's contents don't depend (a lot) on it being written in C++; it's all machine code. That code might have been optimized so a lot of information that was present in the original source code is simply gone.
That said, here is one article that goes through a lot of material about doing this.
I think a C++ DLL is a machine code file. Therefore decompiling will only result in assembler code. If you can read that and create C++ from that you're good to go.
There are no decompilers which I know about. W32dasm is good Win32 disassembler.
There really isn't any way of doing this as most of the useful information is discarded in the compilation process. However, you may want to take a look at this site to see if you can find some way of extracting something from the DLL.
The closest you will ever get to doing such thing is a dissasembler, or debug info (Log2Vis.pdb).
