摘要:复制代码代码如下:usingSystem;usingSystem.Collections.Generic;usingSystem.Compo...

复制代码 代码如下:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using System.Runtime.InteropServices;

namespace BrowserMouseClick

{

public partial class Form1 : Form

{

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]

static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

[DllImport("user32.dll", SetLastError = true)]

static extern IntPtr GetWindow(IntPtr hWnd, uint uCmd);

[DllImport("user32.dll", CharSet = CharSet.Auto)]

static extern int GetClassName(IntPtr hWnd, StringBuilder lpClassName, int nMaxCount);

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

webBrowser1.Navigate("http://www.devpub.com");

}

private void btnMouseClick_Click(object sender, EventArgs e)

{

int x = 100; // X coordinate of the click

int y = 80; // Y coordinate of the click

IntPtr handle = webBrowser1.Handle;

StringBuilder className = new StringBuilder(100);

while (className.ToString() != "Internet Explorer_Server") // The class control for the browser

{

handle = GetWindow(handle, 5); // Get a handle to the child window

GetClassName(handle, className, className.Capacity);

}

IntPtr lParam = (IntPtr)((y << 16) | x); // The coordinates

IntPtr wParam = IntPtr.Zero; // Additional parameters for the click (e.g. Ctrl)

const uint downCode = 0x201; // Left click down code

const uint upCode = 0x202; // Left click up code

SendMessage(handle, downCode, wParam, lParam); // Mouse button down

SendMessage(handle, upCode, wParam, lParam); // Mouse button up

}

}

}

想在WebBrowser控件里面模拟鼠标点击,在百度上找了半天,怎么也找不到,还是google强大,在一个国外网站上找到的,代码比较清楚了,不做说明。
