Q: Identifying the origin of a DLL How do I determine what compiler was used to create a DLL? 
I have a DLL - is it possible to find out how the DLL was created (.NET/C++/Labview etc). I don't have the source of the DLL file. I tried checking with decompilers also, but it does not provide me any information of how the DLL was created.

A: There are a number of tools for performing this sort of analysis. Have a look here for a summary of some popular options (namely PEiD, Exeinfo PE, and Language 2000).
