我正在制作的表单上有两个列表框。第一个列表框链接到具有各种公司名称的表。我追求的目标是双击公司名称,然后将值插入第二个列表框中。
在我尝试添加代码以防止重复项出现在第二个列表框中之前,它一直运行良好,因此您不会无意间两次插入同一家公司。我尝试了几次不同的迭代,但是没有运气。有人能帮忙吗?我的最终目标是弹出msgbox
,警告用户不允许重复。
Private Sub ContractorLstbx_DblClick(Cancel As Integer)
Dim found As Boolean
found = False
Dim ID As Long
Dim Contractor As String
For Each newItem In Me.ContractorLstbx.ItemsSelected
For j = 0 To Me.SelectedContractorLst.ListCount - 1
If (Me!ContractorLstbx.ItemData(newItem).Column(1) = Me.SelectedContractorLst.ItemData(j).Column(1)) Then
found = True
Exit For
End If
Next j
If found = False Then
ID = Me.ContractorLstbx.ItemData(newItem)
Me.SelectedContractorLst.AddItem ContractorLstbx!.ItemData(newItem).Column(0) & ";" & Me!ContractorLstbx.ItemData(newItem).Column(1)
End If
found = False
Next newItem
End Sub

这是您的解决方案的完整代码。我在测试样本上尝试过,并且工作正常。只需复制并粘贴代码即可。如果您需要比较时区分大小写(我是说A <> a),请使用Option Compare Binary
,如下面的代码所示。如果要求不区分大小写(A = a),则保留默认值Option Compare Database
,或者最好使用Option Compare Text
