在xp下，FindWindowEx如何进一步获取子窗口？
下面代码，已经成功地获取到了，装载所有任务图标的区域。

handle3就是这个区域的句柄，接着如何进一步获取子窗口？

我要获取的目标子窗口是：程序名是text.exe、标题是"TEXT-1"的那个任务窗体。

C# code

         [DllImport("user32.dll")]        private static extern int FindWindow(string className, string windowText);        [DllImport("user32.dll")]        private static extern int FindWindowEx(int hWnd1, int hWnd2, string lpsz1, string lpsz2);         private void Button_Click(object sender, RoutedEventArgs e)        {            int handle0 = FindWindow("Shell_TrayWnd", null);            int handle1 = FindWindowEx(handle0, 0, "ReBarWindow32", null);            int handle2 = FindWindowEx(handle1, 0, "MSTaskSwWClass", null);            int handle3 = FindWindowEx(handle2, 0, "ToolbarWindow32", null);         }
