How do I see functions in a DLL?

If a DLL is written in one of the . NET languages and if you only want to view what functions, there is a reference to this DLL in the project. Then doubleclick the DLL in the references folder and then you will see what functions it has in the OBJECT EXPLORER window.

How can I see the parameters in a DLL?

If it is a COM Dll, then register it, use OLE view to know the Interafaces and parameters. Show activity on this post. Show activity on this post. If the only piece of information you have is the undecorated function name, then unfortunately it's not possible to deduce the function parameters from that alone.

How do I expose a function in a DLL?

In your library build project create a define LIBRARY_EXPORTS this will cause your functions to be exported for your DLL build. Since LIBRARY_EXPORTS will not be defined in a project consuming the DLL, when that project includes the header file of your library all of the functions will be imported instead.

How do I view DLL contents in Visual Studio?

You can easily open a DLL file in Visual Studio the same way you would any other file. To do so, click File in the menu bar at the top, followed by Open. Then click File and select the DLL file you want to open and click Open. This will open the DLL file in a new Resource Editor window.


For native code it's probably best to use Dependency Walker. It also possible to use dumpbin command line utility that comes with Visual Studio.


Use the free DLL Export Viewer, it is very easy to use.


You may try the Object Browser in Visual Studio.

Select Edit Custom Component Set. From there, you can choose from a variety of .NET, COM or project libraries or just import external DLLs via Browse.


Use dumpbin command-line.

  • dumpbin /IMPORTS <path-to-file> should provide the function imported into that DLL.
  • dumpbin /EXPORTS <path-to-file> should provide the functions it exports.
