	// one window. If we want to create multiple windows, each hosting its own browser object (to display its
	// own web page), then we need to create unique IOleClientSite, IOleInPlaceSite, and IOleInPlaceFrame
	// structs for each window. And we'll put an extra field at the end of those structs to store our extra
	// data such as a window handle. So, our functions won't have to touch global data, and can therefore be
	// re-entrant and work with multiple objects/windows.
	//
	// Remember that a pointer to our IOleClientSite we create here will be passed as the first arg to every
	// one of our IOleClientSite functions. Ditto with the IOleInPlaceFrame object we create here, and the
	// IOleInPlaceFrame functions. So, our functions are able to retrieve the window handle we'll store here,
	// and then, they'll work with all such windows containing a browser control.
	//
	// Furthermore, since the browser will be calling our IOleClientSite's QueryInterface to get a pointer to
	// our IOleInPlaceSite and IDocHostUIHandler objects, that means that our IOleClientSite QueryInterface
	// must have an easy way to grab those pointers. Probably the easiest thing to do is just embed our

	// a _IOleClientSiteEx. As long as they come after the pointer to the IOleClientSite VTable, then we're
	// ok.
	//
	// Of course, we need to GlobalAlloc the above structs now. We'll just get all 4 with a single call to
	// GlobalAlloc, especially since 3 of them are all contained inside of our _IOleClientSiteEx anyway.

	// NOTE: We need this pointer to interact with and control the browser. With normal WIN32 controls such as a
	// Static, Edit, Combobox, etc, you obtain an HWND and send messages to it with SendMessage(). Not so with
	// the browser object. You need to get a pointer to its "base structure" (as returned by CoGetClassObject()). This
	// structure contains an array of pointers to functions you can call within the browser object. Actually, the
	// base structure contains a 'lpVtbl' field that is a pointer to that array. We'll call the array a 'VTable'.
	//
	// For example, the browser object happens to have a SetHostNames() function we want to call. So, after we
	// retrieve the pointer to the browser object (in a local we'll name 'browserObject'), then we can call that
	// function, and pass it args, as so:
	//
	// browserObject->lpVtbl->SetHostNames(browserObject, SomeString, SomeString);
	//
	// There's our pointer to the browser object in 'browserObject'. And there's the pointer to the browser object's
	// VTable in 'browserObject->lpVtbl'. And the pointer to the SetHostNames function happens to be stored in an
	// field named 'SetHostNames' within the VTable. So we are actually indirectly calling SetHostNames by using
	// a pointer to it. That's how you use a VTable.
	//
	// NOTE: We pass our _IOleClientSiteEx struct and lie -- saying that it's a IOleClientSite. It's ok. A
	// _IOleClientSiteEx struct starts with an embedded IOleClientSite. So the browser won't care, and we want

				// these names in its titlebar.
				//	
				// We are passing 3 args to SetHostNames. You'll note that the first arg to SetHostNames is the base
				// address of our browser control. This is something that you always have to remember when working in C
				// (as opposed to C++). When calling a VTable function, the first arg to that function must always be the
				// structure which contains the VTable. (In this case, that's the browser control itself). Why? That's
				// because that function is always assumed to be written in C++. And the first argument to any C++ function
				// must be its 'this' pointer (ie, the base address of its class, which in this case is our browser object
				// pointer). In C++, you don't have to pass this first arg, because the C++ compiler is smart enough to
				// produce an executable that always adds this first arg. In fact, the C++ compiler is smart enough to
				// know to fetch the function pointer from the VTable, so you don't even need to reference that. In other
				// words, the C++ equivalent code would be:
				//
				// browserObject->SetHostNames(L"My Host Name", 0);
				//
				// So, when you're trying to convert C++ code to C, always remember to add this first arg whenever you're
				// dealing with a VTable (ie, the field is usually named 'lpVtbl') in the standard objects, and also add
				// the reference to the VTable itself.
