实现效果;
知识运用:
API FindWindow函数 //可用来返回任务栏所在窗口Shell_TrayWnd的句柄
IpClassName :要返回的窗口的类名称字符串指针
IpWindowName:要返回的窗口的名称
GetWindowRect函数 //获取任何一个窗口的矩阵范围的函数
hwnd:目标窗口的句柄
IpRect:存储窗口区域的Rectangle结构变量
实现代码:
[DllImport("user32.dll")] public static extern int FindWindow(string IpClassName,string IpWindowName); [DllImport("user32.dll")] public static extern int GetWindowRect(int hwnd,ref Rectangle IpRect); Rectangle rect; private void button1_Click(object sender, EventArgs e) { if ((GetWindowRect(FindWindow("Shell_TrayWnd", null), ref rect)) == 0) return; else { textBox1.Text = Convert.ToString(rect.Left); textBox2.Text = Convert.ToString(rect.Top); textBox3.Text = Convert.ToString(rect.Right); textBox4.Text = Convert.ToString(rect.Bottom); } }
