Date: 2011jul29 OS: Windows Q. Windows: see what DLLs my program uses A. There is a nice graphical tool called DEPENDS.EXE which you can use to open your EXE (or DLL). It shows the DLLs your program uses. And the DLLs those DLLs, in turn, use. Its proper name is Dependency Walker. And its part of Microsoft Visual Studio.
