程序的功能是将vlookup的结果返回到要查找的值的同一单元格中,但它有两个问题。
1。如果' no'它会一次又一次地返回消息框。在消息框中按下了吗?
2。如果在空白单元格上按下输入,我不想显示消息框吗?
这是代码
Sub Worksheet_Change(ByVal Target As Range)
Dim Ret_type As Integer
Dim strMsg As String
Dim strTitle As String
If Target.Count > 1 Then Exit Sub
If Not Intersect(Target, Range("A1:A114")) Is Nothing Then
Application.EnableEvents = False
Table2 = Sheet2.Range("C2:D3")
strTitle = "Alert"
strMsg = "Combination not found press Yes for manual entry"
On Error Resume Next
Target.Value = Application.WorksheetFunction.VLookup(Target.Value, Table2, 2, False)
Application.EnableEvents = True
If Err.Number <> 0 Then
Ret_type = MsgBox(strMsg, vbYesNo, strTitle)
Select Case Ret_type
Case 7
ActiveCell.Offset(-1, 0).Clear
End Select
End If
On Error GoTo 0 ''no error, coming back to default conditions
End If
End Sub
答案 0 :(得分:0)
1:确保仅在代码进行每次更改后重新启用事件。否则它将继续在递归中重新启动。
2:如果目标为空,请检查代码的开头。
+1:不要在像这样的宏中使用activecell.offset;您的用户可能已经单击了任何单元格,在这种情况下,偏移是没有意义的。改为使用Target变量。
你的代码非常混乱,我不确定它在这一点上是否完全合理。无论如何,这是一个工作版本。有关兴趣点,请参阅我的在线评论。
我也简化了一点,删除了一些无用的结构。
Sub Worksheet_Change(ByVal Target As Range)
Dim strMsg As String
Dim strTitle As String
If Target.Cells.Count > 1 Then Exit Sub
If Target.Value = "" Then Exit Sub 'don't bother with a blank cell
If Not Intersect(Target, Range("A1:A114")) Is Nothing Then
Application.EnableEvents = False
Table2 = Sheet2.Range("C2:D3")
strTitle = "Alert"
strMsg = "Combination not found press Yes for manual entry"
On Error Resume Next
Target.Value = Application.WorksheetFunction.VLookup(Target.Value, Table2, 2, False)
If Err.Number <> 0 Then
If MsgBox(strMsg, vbYesNo, strTitle) = vbYes Then
Target.Clear 'Better than the offset version; this works also if your user uses tab or mouse click, not only enter
End If
End If
On Error GoTo 0
Application.EnableEvents = True 'only re-enable events AFTER having changed everything you want to change
End If
End Sub
