Navigates forward one item in the history list.
This method has no parameters.
During a browsing session, the WebBrowser control and Windows Internet Explorer maintain a history list of all Web sites visited during a session, unless you specify the navNoHistory flag when you use the Navigate method.
Use the CommandStateChange event to check the enabled state of forward navigation. If the event's CSC_NAVIGATEFORWARD command is disabled, the end of the history list has been reached, and the GoForward method should not be used.
