Reusing the Web Browser Control
The WebBrowser control is utilized to work for navigation, hyperlinking, history lists, favorites, and security. It serves as a filter for the MSHTML component also known as a DocObject that can show HTML. The MSHTML component displays the Dynamic HTML (DHTML) object model, Microsoft ActiveX controls and script languages, and parses and renders HTML.
Programs and Applications can also use the WebBrowser control to host Active documents. This means that richly formatted documents, such as Microsoft Excel spreadsheets or Microsoft Word documents, can be opened and edited in place from within the WebBrowser control.
