PInvoke.net will show you how to setup your P/Invoke so that you can call the method from managed code (assuming that's what you want to know.)

pinvoke.net is a great site for familiarizing yourself with WIN32 APIs, or for reference, complete with sample usages.

It's hard to understand your question, but this link shows how it is possible to call FindWindowEx from C# application.

Basically, you declare it like that:

[DllImport("user32.dll", SetLastError = true)]
 static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass, string lpszWindow);

and then call it:

handle = FindWindowEx(hwnd, IntPtr.Zero, "WindowName", IntPtr.Zero);

A great source of information for calling windows APIs from c# is the pinvoke site.

It has a list of the api's, examples of how to use most. And it also has other options in .net for several APIs
