下面是类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
namespace txj
{
public class Browser
{
[DllImport("User32.DLL")]
public static extern int SendMessage(IntPtr hWnd, uint Msg, int wParam, int lParam);
[DllImport("User32.DLL")]
public static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass, string lpszWindow);
public int IDM_ADDFAVORITES = 2261;
public uint WM_COMMAND = 0x0111;
private System.Windows.Forms.WebBrowser myBrowser;
public Browser(System.Windows.Forms.WebBrowser webBrowser)
{
myBrowser = webBrowser;
}
public void back()
{
myBrowser.GoBack();
}
public void forward()
{
myBrowser.GoForward();
}
public void stop()
{
myBrowser.Stop();
}
public void refresh()
{
myBrowser.Refresh();
}
public void home()
{
myBrowser.GoHome();
}
public void addFav()
{
IntPtr vHandle = myBrowser.Handle;
vHandle = FindWindowEx(vHandle, IntPtr.Zero, "Shell Embedding", null);
vHandle = FindWindowEx(vHandle, IntPtr.Zero, "Shell DocObject View", null);
vHandle = FindWindowEx(vHandle, IntPtr.Zero, "Internet Explorer_Server", null);
SendMessage(vHandle, WM_COMMAND, IDM_ADDFAVORITES, (int)vHandle);
}
}
}
现在遇到几个问题：(1）多页面后前进后退等操作都只在第一页进行。
(2) 网页标题是在页面完成后再给tabpage的，导致打开网页时，选择其他tabpage 则网页标题就给选中 的那个tabpage了。
本人新手，代码中还有问题的话 也请高手们指点下，谢谢！
