what is the problem? Elaborate your problem in detail I think you want to call the function(or method) of a dll on the click event of button. simply add the reference of dll to your project and use it.

First, you haven't asked a question. You also haven't described any kind of problem, or provided any detail into what you have, and what's you've done. If you want to call a function in a .DLL, there's two basic methods of going about it. Which one you use depends on the type of .DLL you're talking about. If it's a normal library .DLL, you have to use P/Invoke. This means you better have the documentation on the .DLL so you can create a correct function header to use. Google for "Pinvoke vb.net" for millions of examples. If it's a COM-based .DLL, it has to be registered properly, the you can open your project properties, click on the References tab, then add a COM reference to the .DLL. You can then use the objects exposed by that library just like you would normal .NET classes.
