The web-browser is an Activex control hosted in the CVI panel. You are limited to the ActiveX methods and properties exposed by the control when it comes to accessing any features of the control. These functions are wrapped as C functions in the inet.fp instrument of the project. You can also find more documentation about this Microsoft ActiveX control on MSDN. For example, the IWebBrowser2 interface is documented at:

I am able to get the interface pointer for the Document object as follows:

IUnknown *pUnk = 0;
SHDocVw_GetProperty (ieHandle, 0, SHDocVw_IWebBrowser2Document, CAVT_UNKNOWN, &pUnk);

// Do something with the document interface

if (pUnk)
    pUnk->lpVtbl->Release(pUnk);

I tried this at the end of the TellIEToNavigate function of samples/activex/ie/iedemo.c.
