>I would guess that it displays whatever you pass to it the same way IE5.0 (or whatever version used this rendering engine) did. I'm pretty sure that what is available as the OCX is the same engine that was used in some version of IE. Of course, that's just something I heard way back when, so it may not be accurate.

The Microsoft Web Browser ActiveX control is Internet Explorer, it is the same engine based on what version of IE you have installed. It is used in several parts of VFP itself, the Component Gallery, the Task Pane, and in FFC via _WebBrowser4 (for IE4 and above), and _WebBrowser3 (for IE3). I wrote those FFC classes, and the code in the Component Gallery (Class Browser), and a few other tools in the 90s. I first hosted the web browser control on a VFP form in 1996. DHTML was introduced in IE 4.0. The architecture and the overall DOM interface has been the same since IE 4.0, small features added but all backward compatible to IE 4.0. Info about hosting the WBC on a VFP form is the same for a VB form, so any docs you see about VB apply about the same for VFP. Rick Strahl has a good whitepaper on this at http://west-wind.com/presentations/shellapi/shellapi.asp, he has done sessions on this topic at conferences for years.
