自己写了个简易的计算器程序，有兴趣的看下
很简易的一个计算器，没什么技术含量~
--------------------编程问答--------------------
加油
--------------------编程问答--------------------
加油。
--------------------编程问答--------------------
可以模仿windows自带的计算器写一个
--------------------编程问答--------------------
http://download.csdn.net/detail/wujianfei0428/4881866贴个下载链接~
--------------------编程问答--------------------
加油哦～～
--------------------编程问答--------------------
除
--------------------编程问答--------------------
有这个想法
--------------------编程问答--------------------
谢谢，同加~
--------------------编程问答--------------------
我这有好多计算器版本。哎不算啥
--------------------编程问答--------------------
贵在坚持 加油
--------------------编程问答--------------------
自己玩玩的，开心就好了~
--------------------编程问答--------------------
不错顶一下，希望下次的版本可以多加一些功能
--------------------编程问答--------------------
话说....代码你也不发 运行程序也木有 就贴个图上来做什么
--------------------编程问答--------------------
其实4L也是我...
--------------------编程问答--------------------
帮顶，从简单做起。
--------------------编程问答--------------------
计算器要想写到无Bug的程度, 也非常不容易.
--------------------编程问答--------------------
是的，我的这个很简易的，bug很多，比如按等于计算完了后再输数据，没清空tb里面的值。
--------------------编程问答--------------------
看来, 你离考虑超过Int甚至Double边界的时候还有段距离呢......
--------------------编程问答--------------------

--------------------编程问答--------------------
--------------------编程问答--------------------
加油哈！！！
--------------------编程问答--------------------
这个,新人练手啊,但是功能太少了啊
--------------------编程问答--------------------

--------------------编程问答--------------------
加油。来看看，收藏了。呵呵。
--------------------编程问答--------------------
你让我们看什么呀，源码呢
--------------------编程问答--------------------
呵呵。其实如果新手了不错了。。支持一个 --------------------编程问答--------------------
--------------------编程问答--------------------
times new roman，不错。。

--------------------编程问答--------------------
楼主可以的
--------------------编程问答--------------------
发个图来，有毛用。不是说共赏的嘛。。不过，，
--------------------编程问答--------------------
看看，路过，我是新手
--------------------编程问答--------------------
可以交流一下经验 我也写过。 
楼主贴出源码..
--------------------编程问答--------------------
--------------------编程问答--------------------
我只知道计算器是特练手的程序之一。。
--------------------编程问答--------------------
给两个积分吧。
--------------------编程问答--------------------
不错，挺好的，加油！贵在坚持

--------------------编程问答-------------------- 1.简化了代码
2.修正2个bug
3.重新在vss 2010中编译（PS：买了新电脑，win 7直接装vss 2010，花了整整半个小时，微软敢不敢把它做得再大一点~）
--------------------编程问答--------------------
大哥或者大姐 其实你做的这个比我做的那个bug要少点 嘿嘿 大家一起加油啊
补充：.NET技术 , C#
