获取鼠标句柄

（1）引用

using System.Runtime.InteropServices;

(2)调用方法

1、获取窗口标题

[DllImport( "user32.dll" )]　　
public static extern int GetWindowText( IntPtr hWnd, StringBuilder lpString,int nMaxCount );

注：hWnd 窗口句柄 lpString 窗口标题 nMaxCount 最大值

2、获取类名

[DllImport( "user32.dll" )]　　
public static extern int GetClassName( IntPtr hWnd, StringBuilder lpString,int nMaxCount );

注：hWnd 句柄 lpString 类名 nMaxCount 最大值

3、根据坐标获取窗口句柄

[DllImport( "user32.dll" )]　　
public static extern IntPtr WindowFromPoint(Point point);

注：point 坐标

二、显示数据

(1) 获取鼠标坐标

int x = Cursor.Position.X;
int y = Cursor.Position.Y;
this.textBox4.Text = string.Format( "({0},{1})" , x, y);

(2) 获取句柄

Point p = new Point(x,y);
IntPtr formHandle = WindowFromPoint(p);
this.textBox1.Text = formHandle.ToString();

(3) 得到窗口标题

GetWindowText(formHandle,title,title.Capacity);
this.textBox2.Text = title.ToString();

(4)得到窗体的类名

StringBuilder cllassName = new StringBuilder();
GetClassName(formHandle,cllassName,cllassName.Capacity);
this.textBox3.Text = cllassName.ToString();

(5)Load事件

this.timer1.Enabled = !this.timer1.Enabled;

注：动态显示信息
