Hello All,
I have a DLL that I need to find the entry points and the parameters for each entry point. I do not have any instructions from the creator. I'm able to find the entry points by using dumpbin/EXPORTS in visual studio command prompt. I opened the dll in a Hexeditor but I cannot find anything in reference to the specific entry point or its paramters.
My question is first, is this possible? if so, how?
Thanks in advance.

Try the free decompiler, dotPeek, from JetBrains: [^]. Or, try Microsoft's ILDASM that comes with .NET [^].

Long ago, Lutz Roeder's Reflector [^] (free) was the tool of choice for dis-assembly, but then Red Gate Software acquired it, and it is now a commercial product with two versions with different features available [^].

ILSpy, open-source, free, is a new "incarnation" of Reflector [^].

But, best of all, would be to get some information from whoever developed the dll: hacking is not its own reward !

I think he's looking to load in a C/C++ dll into .NET, its not entirely clear but that's what it sounds like to me.

Thanks for your help. I will try your suggestions. Just a note on your comment as far as hacking, I do not condone hacking nor ever done it. This is a dll that does not come with any support even though I have purchased the SDK. I have contacted the vendor and the wait period is quite long.
