可重复使用的WNDCTRL类 这个类基本上容纳了一些隐藏的控件和窗口。一个 WndCtrl对象有两个状态, 即开和关。你必须把这个控件加到m_WndCtrl中。当WndCtrl被打开的时候,控件被创建,当WndCtrl被关闭的时候，控件被隐藏或撤销。WndCtrl将会是所有加到它上面的控件的父节点。WndCtrl可以在关闭或开着的状态下改变大小或重新定位。然而，关闭状态下的大小是静态的，不能被改变。无论大小是否被改变,都将会影响WndCtrl开着的状态- Might duplicate a WNDCTRL kind of this kind which used basically holds some hideaways to control and the window. A WndCtrl object has two conditions, namely opens with the pass. You must control this to add to in m_WndCtrl. When WndCtrl is opened, controls to found, when WndCtrl is closed, controls to hide or to abolish. WndCtrl could be all adds to above it to control the father pitch point. WndCtrl may the condition change the size under the closure either is opening or relocate. However, under the off-position size is the static state, cannot change. Regardless of size whether is changed, all will be able to affect WndCtrl will be opening the condition

以上代码实现修改显示器分辨率和刷新频率的功能,其中#region Windows Form Designer generated code private void InitializeComponent() { this.AutoScaleBaseSize = new System.Drawing.Size(6, 14) this.ClientSize = new System.Drawing.Size(292, 273) this.Text = "改变屏幕分辨率的例子" 好象有点问题,请站长帮忙指正,修改-achieve the above code revision display resolution and refresh frequency features,# region Windows Form Designer generated code private void InitializeComponent () (this.AutoScaleBaseSize = new System.Drawing.Size (6, 14) = new System.Drawing this.ClientSize . Size (292, 273) = this.Text "change the screen resolution examples" seems a little problem, please help correct station revised
