You’re probably aware that using dumpbin.exe is very useful if you need to P/Invoke. dumpbinGUI.exe is a tool that I’ve been using for years that you might be interested in. It adds a simply context menu to the Windows shell, so you can right click any DLL or LIB and view it’s exports (among other things).
The install leaves a bit to be desired. You have to have a dev tool installed, and you must modify your path to allow dumpbinGUI to find a couple files. If you have Studio 2003 installed in the default location, add these to your system path:
C:Program FilesMicrosoft Visual Studio .NET 2003Vc7bin
C:Program FilesMicrosoft Visual Studio .NET 2003Common7IDE
