Look into Microsoft's Virtual Earth SDK. It might do what you want, but I don't know for sure, because I've never used it.

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.

Try out something and if you get stuck then ask.

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.

There's tons of examples out there. You take those examples, learn the basic techniques from them, then modify or rewrite the examples to fit your needs.
try Google search for Setup & deployment VB.NET[^]

But could you please tell me about the COM components I have talked about?
I Wanted to know after addidng these components (VLC player and WMP), is it necessary that the installed system should install the players, or not necessary

thanks

I think, you can copy the COM component reference in Debug/Release folder of your project directory and after that when you create setup, include this references.

when you add COM component, a references is added to your application. Navigate Menu Project--->Properties --->References Tab
This tab show all the references which is used by your application.Select appropriate COM COmponent Refrences and then from Properties choose 'Copy Local' to TRUE

hope this helps

thanks a lot...

one more thing i wanted to confirm is what is copy to local means? It copies the dll to application or what?

And I can see the option "imported namespaces" too with so many checkboxes down... What am I supposed to do that for deploying purpose?

Thanks in advance
