获取鼠标句柄

一、调用user32.dll

    

  （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
