Vba 结束通过Excel中的工作表的For循环
如果有人能在以下方面提供帮助,我将不胜感激。以下代码从MS Excel复制一个范围,并将其粘贴到MS PowerPoint中。此外,还有一个循环,它遍历工作簿的所有工作表,并应用相同的复制粘贴公式。然而,当循环到达最后一个工作表时,我正在努力如何“关闭”循环。在代码末尾,我得到一个运行时错误“91”:未设置突出显示Vba 结束通过Excel中的工作表的For循环,vba,excel,for-loop,Vba,Excel,For Loop,如果有人能在以下方面提供帮助,我将不胜感激。以下代码从MS Excel复制一个范围,并将其粘贴到MS PowerPoint中。此外,还有一个循环,它遍历工作簿的所有工作表,并应用相同的复制粘贴公式。然而,当循环到达最后一个工作表时,我正在努力如何“关闭”循环。在代码末尾,我得到一个运行时错误“91”:未设置突出显示sh(ActiveSheet.Index+1)的对象变量或With block变量。当我选择Debug时,请选择 Sub CreateDeck() Dim WSheet_Count

您的脚本在工作表
中的循环工作做得很好,但实际上有一个内置的集合
专门针对这种情况设计
此工作簿。工作表
包含此工作簿
中的所有工作表
——您可以这样循环:
Option Explicit
Public Sub LoopThroughAllWorksheets()
Dim wks As Worksheet
For Each wks In ThisWorkbook.Worksheets
MsgBox "On sheet: " & wks.Index
Next wks
End Sub
For Each sh in ThisWorkbook.Worksheets
'do stuff, like:
'Set Rng = sh.Range("A1:A2")
'etc.
Next sh
这意味着您可以调整For…Next
循环以如下方式工作:
Option Explicit
Public Sub LoopThroughAllWorksheets()
Dim wks As Worksheet
For Each wks In ThisWorkbook.Worksheets
MsgBox "On sheet: " & wks.Index
Next wks
End Sub
For Each sh in ThisWorkbook.Worksheets
'do stuff, like:
'Set Rng = sh.Range("A1:A2")
'etc.
Next sh
利用工作表
集合还可以帮助您避免使用。选择和活动表
,这会给用户带来很多痛苦:
您将变量sh
声明为工作表
,但从未为其赋值。异常试图在状态为“未设置对象变量”时指出这一点
行中:
sh(ActiveSheet.Index + 1).Select
您正试图调用尚未赋值的sh
工作表。看来你在这里做的作业不对。您可以使用类似于ThisWorkbook.Worksheets(ActiveSheet.Index+1)的功能。选择以实现此功能,但您的循环也必须修改才能正常工作
如果您只是尝试循环浏览工作簿中的所有工作表,那么只需使用内置集合,而无需担心如何处理索引
Option Explicit
Dim ws As Worksheet
Sub MessageAllNames()
For Each ws In ThisWorkbook.Worksheets
' Everything that should be contained within your loop, for example...
MsgBox ws.Name
Next ws
End Sub
向上投票!这是一个非常好和正确的答案。你关于避免.Select`和ActiveSheet`的建议非常正确,我看你有经验。我不明白你为什么会被否决。Downvoter,你能解释一下吗?嘿@SQLPolice,谢谢你的客气话。我对否决票也有同样的疑问,但希望帮助OP的主要目标能够实现……谢谢@grovesNL,你说得对,我不知道内置的收藏。使用起来容易多了!对实际对象变量not set error@grovesNL的出色解释
