Possible duplicate:Determine source language from binary?
There is a compiled application (com, exe, etc.).
I want to ask if there is any recognition method in which programming language the application was developed (C #, Delphi, Visual Basic, Visual C ++, etc.)?
You can use PEiD , this tool has been discontinued., But the latest version is still working.
PEiD discovers most common packers, cryptomers, and compilers for PE files. Currently, it can detect over 600 different signatures in PE files.
