VB编程!请问有谁会VB编程，请
我这有一个简单的计算器代码,只能加减乘除。
觉得合适就给点分。
Option Explicit
Dim flg As Boolean, op As Integer, first As Single
Private Sub Command1_Click(Index As Integer)
If Index = 10 Then
Text1。 Text = Text1。Text & "。"
Else
Text1。Text = Text1。Text & CStr(Index)
End If
If Len(Text1) = 2 And Left(Text1, 1) = "0" And Mid(Te...全部
