StringBuilder lpString, //标题
int nMaxCount //最大值
);
//获取类的名字
[DllImport("user32.dll")]
private static extern int GetClassName(
IntPtr hWnd, //句柄
StringBuilder lpString, //类名
int nMaxCount //最大值
);
//根据坐标获取窗口句柄
[DllImport("user32")]
private static extern IntPtr WindowFromPoint(
Point Point //坐标
);
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
this.timer1.Enabled = !this.timer1.Enabled;
}
private void timer1_Tick(object sender, EventArgs e)
{
int x = Cursor.Position.X;
int y = Cursor.Position.Y;
Point p = new Point(x, y);
IntPtr formHandle = WindowFromPoint(p);//得到窗口句柄
StringBuilder title = new StringBuilder(256);
GetWindowText(formHandle, title, title.Capacity);//得到窗口的标题
StringBuilder className = new StringBuilder(256);
GetClassName(formHandle, className, className.Capacity);//得到窗口的句柄
this.textBox1.Text = "窗口句柄:" + formHandle.ToString() + Environment.NewLine + "窗口标题:" + title + Environment.NewLine + "类名:" + className;
}
private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
if(e.KeyCode==Keys.Enter || e.KeyCode==Keys.Space)
{
this.button1.PerformClick();
}
}
}
}
PS: timer1触发不好用。。自己用全局钩子触发的获取方法
