VS2008开发的VB.net数学计算器，由NeverWind撰写，用于新手教程或指导。

　　注意：本程序是简单的四则运算计算器，不自动判定运算顺序，即，当输入1-2*3时候，先计算1-2，再计算-1*3。

　　为方便新手，不在设计界面更改控件属性。对控件属性赋值操作可以直接在窗体设计界面更改，如果你觉得这样一个一个的按键事件很麻烦，可以不手动画控件，在窗口初始化时生成按键数组，然后调用。但此方法不在本程序讨论之列。-The development of mathematical calculator VB.net VS2008 by NeverWind written tutorial or guide for the novice. Note: This program is a simple arithmetic calculator, does not automatically determine the order of operations, that is, the time when the input 1-2* 3, 1-2 first calculated, then calculate the-1* 3. For the convenience of beginners, the interface is not designed to change control properties. Assignment of the control properties can be changed directly in the form design interface, if you think that one of the key events of a lot of trouble, you can not hand animation control buttons in the window generates an array initialization, then calls. However, this method is not in the program discussed.
