设计一个可以适时展开的对话框以便于在对话框中添加更多控件，在单击Advanced按钮时，对话框可以向下展开。

以通过方式创建一个具有扩展功能的Advanced按钮的对话框资源和对话框类，需要在对话框类的OnInisDialg()函数中利用CWnd::MoveWindow()函数将对话框缩为Advanced按钮。这样当单击该按钮时，将使用MoveWindows()函数来切换对话框窗口尺寸。

-The design of a dialog can begin in good time in order to add more in the dialog box controls, click the Advanced button, the dialog can be launched down. Created through the expansion of a function of the dialog box Advanced button dialog resource and class, the need for dialog class OnInisDialg () function to use CWnd:: MoveWindow () function will shrink the dialog box for the Advanced button. So that when click the button, will use MoveWindows () function to switch the dialog box window size.
