Remarks
Internet Explorer8. On WindowsVista, to create an instance of Internet Explorer running at a medium integrity level, passCLSID_InternetExplorerMedium(defined in exdisp.idl) toCoCreateInstance. The resultingInternetExplorerMediumobject supports the same events, methods, and properties as theInternetExplorerobject.
Examples
The following example usesCreateObjectin Microsoft Visual Basic to launch an instance of Internet Explorer.
Dim IE As SHDocVw.InternetExplorerSet IE = CreateObject("InternetExplorer.Application")
The following C# example launches an instance of Internet Explorer and navigates to a Web page. The code also demonstrates how to create an event handler to listen for theBeforeNavigate2event. The project requires a reference to the Microsoft Internet Controls (SHDocVw) type library.
using System;using System.Collections.Generic;using System.Text;namespace ConsoleApplication1{ class EventHandlers { public void OnBeforeNavigate2(object sender, ref object URL, ref object Flags, ref object Target, ref object PostData, ref object Headers, ref bool Cancel) { Console.WriteLine("BeforeNavigate2 fired!"); } } class Program { static void Main(string[] args) { EventHandlers e = new EventHandlers(); SHDocVw.InternetExplorer IE = new SHDocVw.InternetExplorer(); object Empty = 0; object URL = "http://www.live.com"; // override BeforeNavigate2 event IE.BeforeNavigate2 += new SHDocVw.DWebBrowserEvents2_BeforeNavigate2EventHandler( e.OnBeforeNavigate2); IE.Visible = true; IE.Navigate2(ref URL, ref Empty, ref Empty, ref Empty, ref Empty); System.Threading.Thread.Sleep(5000); IE.Quit(); } }}
