我知道可以使用If
声明,但出于好奇,如标题中所述,是否可以使用 SELECT
声明做某事为粗体 以下?我已经提交了我的全部 Sub
如下以便更好地理解:
子 addNewCust_Click()
Dim response As String
response = Application.InputBox(prompt:="", Title:="New customer name", Type:=2)
Select Case response
Case False
Exit Sub
'Check if response is not an empty value AND record found in "CustomerList"
Case Is <> "" & WorksheetFunction.CountIf(Worksheets("CustomerList").Range("B:B"), response) > 0
MsgBox "'" & response & "' already exists on this sheet."
Call addNewCust_Click
'Check if response is not an empty value and record is not found in "Customerlist"
Case Is <> "" & WorksheetFunction.CountIf(Worksheets("CustomerList").Range("B:B"), response) < 1
Sheets("CustomerList").Range("B1048576").End(xlUp).Offset(1, 0).Value = response
MsgBox "'" & response & "' successfully entered!"**
Case Else
MsgBox "Field is empty!"
Call addNewCust_Click
End Select
End Sub
最佳答案
像这样?
Sub addNewCust_Click()
Dim response As String
response = Application.InputBox(prompt:="", Title:="New customer name", Type:=2)
Select Case response
Case False: Exit Sub
'Check if response is not an empty value AND record found in "CustomerList"
Case Is <> ""
If WorksheetFunction.CountIf(Worksheets("CustomerList").Range("B:B"), response) > 0 Then
MsgBox "'" & response & "' already exists on this sheet."
Call addNewCust_Click
Else
Sheets("CustomerList").Range("B1048576").End(xlUp).Offset(1, 0).Value = response
MsgBox "'" & response & "' successfully entered!"
End If
Case Else
MsgBox "Field is empty!"
Call addNewCust_Click
End Select
End Sub
跟进(来自评论)
Select Case
被认为比 If-Endif
快但是对于这么小的场景,效率比较是徒劳的。更重要的是如何编写代码下面是另一种方式。我喜欢这种方式,因为事情被分解成更小的部分,并且一切都被正确地声明了。我没有触及下面的错误处理。详情见这里analysis .
下面的方法很有用,因为
Codenames
Range("B1048576")
那么上述代码在 Excel 2003 中将无法使用。示例代码
Sub addNewCust_Click()
Dim ws As Worksheet
Dim Lrow As Long
Dim response
'~~> Set the relevant worksheet
Set ws = ThisWorkbook.Worksheets("CustomerList")
With ws
Do
'~~> Get user response
response = Application.InputBox(prompt:="", Title:="New customer name", Type:=2)
Select Case response
Case False: Exit Sub '<~~ If user presses cancel or closes using 'X'
Case "": MsgBox "Field is empty!" '<~~ If user enters a blank entry
Case Else
'~~> Check if the entry exists
If WorksheetFunction.CountIf(.Range("B:B"), response) > 0 Then
MsgBox "'" & response & "' already exists on this sheet."
Else
'~~> Get last Row
Lrow = .Range("B" & .Rows.Count).End(xlUp).Row + 1
'~~> Add the new entry
.Range("B" & Lrow).Value = response
MsgBox "'" & response & "' successfully entered!"
Exit Do 'OR Exit Sub (As Applicable)
End If
End Select
Loop
End With
End Sub
