VB简单计算器编程代码(附图)

VB计算器此计算器能够实现加减乘除等一系列的功能。

还有实现显示系统时间的附加功能。

程序设计：0-9和点在command1的组内。

其他的按钮式运算符和其他功能。

正切和余切有对特殊值进行警告，除也有对除数为零的情况提示警告，还有阶乘等一系列计算溢出的情况提出警告，还有很多需要完善。

这仅供参考。

VB程序简单计算器最近学完VB，感觉很好，写了个计算器程序，虽然花了不少时间，可也着实高兴。

其中遇到很多问题，最终也在各种资料中得到解决。

现在附上截图和全部代码，希望和大家交流一下，相互学习。

也希望能帮助到准备做计算器的同学。

计算器最终执行文件图标：计算器包括三个窗体（form）：主页面form1：其中的“欢迎各位到此一游”是闪烁效果，呵呵，是自己想着无聊，就想出这么个玩意。

与计算器计算功能无关。

具体实现看下来代码。

Form1的实现代码：Public haha As BooleanPrivate Sub Command1_Click()Dim a As Integera = MsgBox("亲爱的你，真的想要退出本系统吗？", _vbYesNo + vbInformation + vbDefaultButton1, "退出系统前的询问撒(⊙o⊙)")If a = 6 Then '表示当选择“是”的时候的返回值EndEnd IfEnd SubPrivate Sub Command2_Click()Me.HideForm2.ShowEnd SubPrivate Sub Command3_Click()Me.HideForm3.ShowEnd SubPrivate Sub Form_Load()haha = FalseEnd SubPrivate Sub Timer1_Timer()haha = Not hahaIf haha ThenLabel2.ForeColor = &HFF00FFElseLabel2.ForeColor = vbWhiteEnd IfEnd Sub有些像图像等一些可见的控件属性就没在代码里写了，直接在属性里设置了。

页面（form2）：此页面将鼠标点上去，还有意想不到的效果喲。

全部代码为：Dim isFocus1, isFocus2 As BooleanPrivate Sub Command1_Click()If isFocus1 Then '判断焦点在那个文本框中，便于实现按钮输入Text1.Text = Text1.Text & 0End IfIf isFocus2 ThenText2.Text = Text2.Text & 0End IfEnd SubPrivate Sub Command10_Click() If isFocus1 ThenText1.Text = Text1.Text & 9 End IfIf isFocus2 ThenText2.Text = Text2.Text & 9 End IfEnd SubPrivate Sub Command11_Click() If isFocus1 ThenText1.Text = Text1.Text & "."
