Modern计算器—提前体验Windows10的计算器

Win10 Build 9926引入了新版Modern计算器，新计算器采用全新设计的UI，整体上更倾向于扁平，与Win10搭配起来倒也相得益彰。

没有升级到win10就不能使用Modern计算器了嘛？

NO...初二在家也是无聊，没有去所谓的走亲戚，既然无聊，就仿Win10写一个计算器吧。

Windows的计算器不是一般的强大，今天只完成了简单的标准模式（标准模式也不是完整），主要还是体验一下Modern的设计风格。

绘出所有的素材。

由于VB的局限性，使用Command的按钮并不美观，于是，将所有的按钮图片化，并使用Image显示出来。

此处用到了2个 控件组和N个image空间，两个Text控件。

功能：

· 简单的计算

· 最小化

· 窗口移动

素材：

固定好各个键的位置后：

上源码，由于使用了拼音变量命名，还是比较理解的：
