IE编程——应用程序操作IE6

 

应用程序对IE6的操作分类：

 

1. 打开一个新的IE6窗口，并显示指定的页面；

2. 读取当前运行的所有IE6进程及其显示的页面url；

3. 读取指定的IE6窗口对应的IE6进程调用的模块及其线程；

4. 更新指定的IE6窗口url；

5. 关闭指定的IE6窗口；

 

将IE6操作封装为OperationOnIE6类，并将其用到的windows消息常量、windows API等也封装为类，分别为：ConstData、Win32API、CommonIEOperation，并指定这些类的命名空间为AutoOperationOnIE6，具体可参考代码（AutoOperationOnIE6.cs文件）。

using System;using System.Text;using Microsoft.Win32;using System.Threading;using System.Collections;using System.Diagnostics;using System.Runtime.InteropServices;namespace AutoOperationOnIE6{ public class ConstData { #region define message public const int WM_SETTEXT = 0x000C; //set text public const int WM_GETTEXT = 0x000D; //get text public const int WM_KEYDOWN = 0x0100; //key down public const int WM_KEYUP = 0x0101; //key up public const int WM_ACTIVATE = 0x0006; //activate window public const int VK_RETURN = 0x0D; //key value of return #endregion } public class Win32API { #region api function [DllImport("User32.dll")] public static extern int FindWindowEx(int hwndParent, int hwndChildAfter, string lpszClass, string lpszWindow); [DllImport("User32.dll")] public static extern int SendMessage(int hWnd, int Msg, int wParam, StringBuilder lParam); [DllImport("User32.dll")] public static extern int SendMessage(int hWnd, int Msg, int wParam, int lParam); #endregion } public class CommonIEOperation { #region variable private static string defaultBrowserName; //default ie browser name private static string defaultBrowserPath; //default ie browser path #endregion #region Properties public static string DefaultBrowserName { get { return defaultBrowserName; } set { defaultBrowserName = value; } } public static string DefaultBrowserPath { get { return defaultBrowserPath; } set { defaultBrowserPath = value; } } #endregion #region get default browser public static void GetDefaultBrowser() { string strIE = string.Empty; string strIEExe = string.Empty; string[] strsegs; try { RegistryKey regKey = Registry.ClassesRoot; regKey = regKey.OpenSubKey(@"http/shell/open/command"); strIE = regKey.GetValue("").ToString(); strsegs = strIE.Split(new char[1] { '"' }); foreach (string temp in strsegs) { if (temp.Contains(".exe") || temp.Contains(".EXE")) { strIEExe = temp.ToUpper(); break; } } int startPos = strIEExe.LastIndexOf(@"/"); int endPos = strIEExe.IndexOf(".EXE"); if (endPos > startPos) { defaultBrowserName = strIEExe.Substring(startPos + 1, (endPos - startPos) - 1); } defaultBrowserPath = strIEExe.Substring(0, strIEExe.IndexOf(".EXE") + 4); } catch (Exception) { defaultBrowserName = string.Empty; defaultBrowserPath = string.Empty; } } #endregion #region get version of IE private static int GetIEVersion() { try { RegistryKey regKey = Registry.LocalMachine; regKey = regKey.OpenSubKey(@"SOFTWARE/Microsoft/Internet Explorer"); string IEVersion = regKey.GetValue("Version").ToString(); string strVersion = IEVersion.Substring(0, 1); return int.Parse(strVersion); } catch (Exception) { return 6; } } #endregion } public class OperationOnIE6 { #region new a window with url public static Process NewUrl(string defaultIE,string url) { Process p = new Process(); p.StartInfo.FileName = defaultIE; p.StartInfo.Arguments = url; p.Start(); return p; } #endregion #region get url public static string GetUrl(int hIEWnd) { //using spy++ to find the type of window int hCtrlWnd = Win32API.FindWindowEx(hIEWnd, 0, "WorkerW", null); hCtrlWnd = Win32API.FindWindowEx(hCtrlWnd, 0, "ReBarWindow32", null); hCtrlWnd = Win32API.FindWindowEx(hCtrlWnd, 0, "ComboBoxEx32", null); hCtrlWnd = Win32API.FindWindowEx(hCtrlWnd, 0, "ComboBox", null); hCtrlWnd = Win32API.FindWindowEx(hCtrlWnd, 0, "Edit", null); StringBuilder buffer = new StringBuilder(1024); //send message to get url int num = Win32API.SendMessage(hCtrlWnd, ConstData.WM_GETTEXT, 1024, buffer); return buffer.ToString(); } #endregion #region set url public static void SetUrl(int hIEWnd, StringBuilder strUrl) { //using spy++ to find the type of window int hCtrlWnd = Win32API.FindWindowEx(hIEWnd, 0, "WorkerW", null); hCtrlWnd = Win32API.FindWindowEx(hCtrlWnd, 0, "ReBarWindow32", null); hCtrlWnd = Win32API.FindWindowEx(hCtrlWnd, 0, "ComboBoxEx32", null); hCtrlWnd = Win32API.FindWindowEx(hCtrlWnd, 0, "ComboBox", null); int hUrlWnd = Win32API.FindWindowEx(hCtrlWnd, 0, "Edit", null); //set IE url Win32API.SendMessage(hUrlWnd, ConstData.WM_SETTEXT, 0, strUrl); //refresh IE Win32API.SendMessage(hUrlWnd, ConstData.WM_KEYDOWN, ConstData.VK_RETURN, null); //activate the window Win32API.SendMessage(hIEWnd, ConstData.WM_ACTIVATE, 0, null); } #endregion }}

编写应用程序，调用命名空间AutoOperationOnIE6的类。

运行结果如下：
