我目前正在尝试设置一个Do While
循环,其中循环的一部分只执行一次。我正在有效地尝试为一个工作表定义单元格范围,然后让我的循环将相同的单元格范围应用于所有工作表/工作簿,而无需重新指定范围。
这是我到目前为止所做的:
isExecuted = False
Do While FileName <> ""
' Open a workbook in the folder
Set WorkBk = Workbooks.Open(Folder & "\" & FileName)
' Conditional to select range only once
If Not isExecuted Then
Dim rng As Range
Set rng = Application.InputBox("Select a Range", "Obtain Range Object", Type:=8)
Debug.Print (rng.Address)
MsgBox "The cells selected were " & rng.Address
isExecuted = True
End If
Set SourceRange = WorkBk.Worksheets(1).Range(rng.Address)
' more stuff goes here
在调试模式下。第一次执行此循环时,一切都按预期工作,我可以看到我的rng.Address是指定的单元格范围。但是,在第二个循环中,rng.Address变为<ObjectRequired>
,因此脚本的其余部分失败。关于如何将rng.Address永久设置为指定单元格区域的任何想法?

如果没有看到更多代码,很难说具体问题是什么,但我建议使用更简洁的逻辑,而不是这样:
If Not isExecuted Then
Dim rng As Range
Set rng = Application.InputBox("Select a Range", "Obtain Range Object", Type:=8)
Debug.Print (rng.Address)
MsgBox "The cells selected were " & rng.Address
isExecuted = True
End If
这样做:
If rng is Nothing Then
Set rng = Application.InputBox("Select a Range", "Obtain Range Object", Type:=8)
End If
注意:如果您在' more stuff goes here
部分期间关闭了工作簿,那可能会杀死对范围的对象引用
有关如何将
rng.Address
永久设置为指定单元格范围的任何想法?
是的,只保留Address
而不是对象。由于Address
是一个字符串文字,因此即使对象引用超出范围,您也可以将其保留在String
变量中:
Dim addr As String
If addr = vbNullString
addr = Application.InputBox("Select a Range", "Obtain Range Object", Type:=8).Address
End If
Set SourceRange = WorkBk.Worksheets(1).Range(addr)

问题是,Range对象是否连接到第一个工作簿。因此,当您关闭该工作簿时,Range对象将丢失。
您需要在字符串变量中保存地址,以便您可以在每个循环上访问它。
Dim strAddress as String
isExecuted = False
Do While FileName <> ""
' Open a workbook in the folder
Set WorkBk = Workbooks.Open(Folder & "\" & FileName)
' Conditional to select range only once
If Not isExecuted Then
Dim rng As Range
Set rng = Application.InputBox("Select a Range", "Obtain Range Object", Type:=8)
Debug.Print (rng.Address)
MsgBox "The cells selected were " & rng.Address
strAddress = rng.Address
isExecuted = True
End If
Set SourceRange = WorkBk.Worksheets(1).Range(strAddress )
' more stuff goes here

您需要在if语句之外声明变量,更好地在循环之外。否则你无法在if / loop语句之外访问它。
