Does rendering HTML to a window require CLSID_WebBrowser, or just CLSID_HTMLDocument?

Solution for Does rendering HTML to a window require CLSID_WebBrowser, or just CLSID_HTMLDocument?
is Given Below:

I apologize, but I’m a little confused. I was wondering what the simplest way to render an HTML string to an HWND is. This question/answer suggests that all you need is CLSID_HTMLDocument. But does that suffice for rendering? I would have thought that to render, you’d also need CLSID_WebBrowser. Any clarification is greatly appreciated.

It can be done either way, it is a matter of how much of OLE/ActiveX your client implements.

Personally I prefer using CLSID_HTMLDocument and then requesting the window as needed but I was implementing the OLE support rather than relying on an existing framework so your mileage may vary. I suspect with an existing very complete framework the CLSID_WebBrowser route may well be easier.
