有关vb.net制作计算器的问题

判断吧，如果点击+按钮，则一个全局变量为1，-按钮，则全局变量为2.以此类推，然后if或case判断哪个数，如果为1，就两个数相加。

如何编辑计算器功能的应用程序？

Visual Studio2008发布后，有大量的VB.net爱好者抛弃原来的Visual Studio2005平台转向现在流行的Visual Studio2008平台。但是Visual Studio2008有一个缺点就是需要比较高的硬件配置才能正常平稳的运行，所以到现在为止还有一部分人处于观望中，并没有转向这个平台。然而Visual Studio2008的一些新的功能以及优化性比先前版本有了很大的进步。本篇文章将主要介绍怎样利用VB.net去编写一个计算器程序，程序虽然不复杂，但是其中所运用的知识和代码非常具有代表性，在平时开发中也是经常需要用到的。希望对VB.net2008的初学者带来帮助。

打开 Visual Studio 2008。在文件 (File) 菜单上，单击新建项目 (New Project)。 在新建项目 (New Project) 对话框的模板 (Templates) 窗格中，单击 Windows 应用程序(Windows Application)。单击确定 (OK)。

在Form1窗体中添加一个TextBox1控件和19个Button按钮，详细属性设置请查看以下的表格。

如何用VB.NET编写计算器

简单的说拖出一些控件，设置相应的caption和属性等等，双击每个button控件，进行相应的处理，即可

怎么用VB.NET来编一个简单计算机的程序，代码怎么写？

创建一个工程

添加一个按扭

双击按扭

输入如下

msgbox ("Hello World!")

按F5

所有的可视开发工具基本都是这个流程，关键还是要学相关语言标准。
