用HScroll 做加减法运算 OPTION 选择运算符号
Dim ,,s As Long
Private Sub Command1_Click()
If Option1 Then
s = m + n
Label5.Caption = "运算结果：" & m & "+" & n & "=" & s
Else
If Option2 Then
s = m - n
Label5.Caption = "运算结果：" & m & "-" & n & "=" & s
Else
If Option3 Then
s = m * n
Label5.Caption = "运算结果：" & m & "*" & n & "=" & s
Else
s = Format(m / n,"0.00")
Label5.Caption = "运算结果：" & m & "/" & n & "=" & s
End If
End If
End If
End Sub
Private Sub Form_Load()
End Sub
Private Sub HScroll1_Change()
m = HScroll1.Value
Label3.Caption = m
End Sub
Private Sub HScroll2_Change()
n = HScroll2.Value
Label4.Caption = n
End Sub
算不出结果来都等于0

Option Explicit
Dim m!,n!,s As Long
Private Sub Command1_Click()
If Option1 Then
s = m + n
Label5.Caption = "运算结果：" & m & "+" & n & "=" & s
Else
If Option2 Then
s = m - n
Label5.Caption = "运算结果：" & m & "-" & n & "=" & s
Else
If Option3 Then
s = m * n
Label5.Caption = "运算结果：" & m & "*" & n & "=" & s
Else
Label5.Caption = "运算结果：" & m & "/" & n & "=" & Format(m / n,"0.00")
End If
End If
End If
End Sub
Private Sub Form_Load()
Option1.Value = True
End Sub
Private Sub HScroll1_Change()
m = HScroll1.Value
Label3.Caption = m
End Sub
Private Sub HScroll2_Change()
n = HScroll2.Value
Label4.Caption = n
End Sub
