confusion from an MFC NOOB

I'm creating (perhaps that's a strong word) a multiple document web browser. I made the program skeleton using MSVC++6's MFC wizard- a multiple document viewing app loaded up with CHtmlView. What I'm trying to do is get a button on the toolbar to chnge the page that is currently being displayed. The problem is, the class that the toolbar function is in doesn't have access to the HtmlView functions, or access to any of the app's other classes that do. In the case that I include a header file of a class that does, I get flooded with errors. So tell me, how do I call Navigate2() from a toolbar?

One solution is messages. Send a messages to main frame and have it dispatch an appropriate function.

And how might I do that?

Here are some essential Win32 API for sending messages.

SendMessage()
PostMessage()
SendNotifyMessage()
