差异最小为%的工作表更改事件

Question

我有一个工作表更改事件。

原始代码：

Private Sub Worksheet_Change(ByVal Target As Range)
If Range("J12") < Range("G12") Then
MsgBox "Oppps. Your system is not working!"
End If
End Sub

我正试图将代码扩展到：

a。将范围从单个单元格(J12和G12(增加到扩展单元格范围(J12:42、G12:42(。

b。不是由小于(J12<G12(触发改变事件，而是由J12&lgt；G12.

Answer 1

这是更新后的代码。

Private Sub Worksheet_Change(ByVal Target As Range)
Dim diffPercent
'Check that the data is changed between row 12 and 42 and it is even row. eg 12,14,16...42.
If (Target.Row > 10 And Target.Row < 44) And ((Target.Row Mod 2) = 0) Then  'And _
'(Target.Column = 7 Or Target.Column = 10) Then
'Get the values in J ang G columns of that particular row.
number1 = Range("G" & Target.Row).Value
number2 = Range("J" & Target.Row).Value
'Check for presence of both the inputs to calculate difference in percentage.
If Not chkInputs(number1, number2) Then
Exit Sub
End If
'Calculate the percentage difference.
diff = number2 - number1
diffPercent = (diff / number2) * 100
'Give alert if difference more than 10 percent
If diffPercent > 10 Then
MsgBox "Oppps. Your system is not working! The difference is :" & diff & "|" & diffPercent
End If
End If
End Sub
Function chkInputs(number1, number2)
chkInputs = False
If IsNumeric(number1) And IsNumeric(number2) Then
chkInputs = True
End If
End Function
