所以我试图在excel中实现条形码扫描器。它已经作为单元格中的数字输入条形码。在另一栏中,我有一组条形码。因此,当扫描仪提供条形码时,应删除此条形码和另一列中的一个副本。
我已经尝试过excel compare-tables函数,但它既没有删除重复的条形码,也没有能够在条形码列中标记重复项。这意味着:如果条形码列中有两次代码123456,则会将其标记为重复。
所以想象我有条形码123,123,124,125。然后,如果我扫描124,我希望该列仅包含123,123,125,如果我扫描123,我希望它包含123,125。
有没有办法在excel中做到这一点,或者我是否需要特定的软件,如果有,那么使用哪个?
您可以尝试在工作表更改事件中导入以下代码,修改它并尝试:
Option Explicit
Private Sub Worksheet_Change(ByVal Target As Range)
Dim BarCode As String
Dim LastRowA As Long, LastRowC As Long, i As Long, Times As Long
Dim arr As Variant
'Let us assume that:
'1. All bar codes appears in column A
'2. The Selected bar code are in cell B2
'3. And the results are in column C
With ThisWorkbook.Worksheets("Sheet1")
If Not Intersect(Target, .Range("B2")) Is Nothing And Target.Count = 1 Then '<- Check if there is any change in cell B2
LastRowC = .Cells(.Rows.Count, "C").End(xlUp).Row
Application.EnableEvents = False
If LastRowC > 1 Then
.Range("C2:C" & LastRowC).Clear '<- If there are data in the results field clear them
End If
BarCode = Target.Value '<- Get the code imported
LastRowA = .Cells(.Rows.Count, "A").End(xlUp).Row
arr = .Range("A2:A" & LastRowA) '<- Create an array with all the bar codes
For i = LBound(arr) To UBound(arr) '<- Loop codes
Debug.Print arr(i, 1)
If arr(i, 1) = BarCode Then
Times = Times + 1
If Times > 1 Then
LastRowC = .Cells(.Rows.Count, "C").End(xlUp).Row
.Range("C" & LastRowC + 1).Value = arr(i, 1)
End If
Else
LastRowC = .Cells(.Rows.Count, "C").End(xlUp).Row
.Range("C" & LastRowC + 1).Value = arr(i, 1)
End If
Next i
Application.EnableEvents = True
End If
End With
End Sub
结果:
