Loading HTML content from a Stream

Loading HTML content from a Stream(2) The IWebBrowser2::Navigate2 method of the IWebBrowser2 interface enables you to navigate the browser to a URL. In the following sample code, the IWebBrowser2::Navigate2 method is used to navigate to the about:blank page. Navigating to this empty page ensures that MSHTML is loaded and that the HTML elements are available through the Dynamic HTML (DHTML) Object Model.

This example demonstrates how to navigate the WebBrowser control to an empty page. The variable m_pBrowser contains the IWebBrowser2 interface pointer obtained from the WebBrowser control.

m_pBrowser->Navigate2( _T("about:blank"), NULL, NULL, NULL, NULL );

Availability of the DHTML Object Model

The DHTML Object Model is used to Access and manipulate the contents of an HTML page and is not available until the page is loaded. Your application determines that a page is loaded by handling the DWebBrowserEvents2::DocumentComplete event of the WebBrowser control. This event may be fired once for each frame in the page, and once when the top frame of the document is loaded. You can determine if the DWebBrowserEvents2::DocumentComplete event is for the top frame by comparing the IDispatch interface pointer passed by this event with that of the WebBrowser control.
