(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
