使用excel激活工作表VBA

Question

我在文件夹中有一个“工作簿A”文件。每两周发送一次更新的版本给我。我想从另一个工作簿“工作簿B”打开此工作簿，同时删除“工作簿A”中的空白行。

打开和删除操作将通过使用宏来进行。

这是我迄今为止的代码。

Sub RemoveEmptyRows() 
    ' this macro will remove all rows that contain no data 
    ' ive named 2 variables of data type string 
    Dim file_name As String 
    Dim sheet_name As String 

    file_name = "C:\Users\Desktop\Workstation_A\Workbook_A.xlsm" 
    'Change to whatever file i want 
    sheet_name = "Worksheet_A" 'Change to whatever sheet i want 

    ' variables "i" and "LastRow" are needed for the for loop 
    Dim i As Long 
    Dim LastRow As Long 

    ' we set wb as a new work book since we have to open it 
    Dim wb As New Workbook 

    ' To open and activate workbook 
    ' it opens and activates the workbook_A and activates the worksheet_A 
    Set wb = Application.Workbooks.Open(file_name) 
    wb.Sheets(sheet_name).Activate 

    ' (xlCellTypeLastCell).Row is used to find the last cell of the last row 
    ' i have also turned off screen updating 
    LastRow = wb.ActiveSheet.Cells.SpecialCells(xlCellTypeLastCell).Row 
    Application.ScreenUpdating = False 

    ' here i am using a step 
    ' the step is negative 
    ' therefore i start from the last row and go to the 1st in steps of 1 
    For i = LastRow To 1 Step -1 
    ' Count A - Counts the number of cells that are not empty and the 
    ' values within the list of arguments (wb..ActiveSheet.Rows(i)) 
    ' Afterwards deleting the rows that are totally blank 
     If WorksheetFunction.CountA(wb.ActiveSheet.Rows(i)) = 0 Then 
      wb.ActiveSheet.Rows(i).EntireRow.Delete 
     End If 
    Next i 

    ' used to update screen 
    Application.ScreenUpdating = True 
End Sub 

工作片名称包含Worksheet_A作为其名称后跟一个日期的一部分。例如Worksheet_A 11-2-15。

在我的代码，我已经赋值的变量sheet_name到Worksheet_A

sheet_name = "Worksheet_A" 

进一步压低我用

.Sheets(sheet_name).Activate 

激活工作表。我觉得有下面一行的一个问题：

sheet_name = "Worksheet_A" 

因为sheet_name是不完全Worksheet_A它只包含Worksheet_A作为其名称的一部分。

这是造成problem.The工作簿中打开，但不会出现空白行的删除。
此外还会显示一条错误消息。

运行时错误9：下标超出范围。

如何修改我的代码以便工作表被激活并执行宏操作？

Answer 1

is it possible to solve this by using Like or Contain statements?
从您的评论，是的。打开工作簿后，重复这样的工作表集合：

Dim sh As Worksheet 
For Each sh In wb.Sheets 
    If InStr(sh.Name, "WorkSheet_A") <> 0 Then 
     sheet_Name = sh.Name: Exit For 
    End If 
Next 

或者您可以抓住该对象并直接在其上工作。

Dim sh As Worksheet, mysh As Worksheet 
For Each sh In wb.Sheets 
    If InStr(sh.Name, "WorkSheet_A") <> 0 Then 
     Set mysh = sh: Exit For 
    End If 
Next 

LastRow = mysh.Cells.SpecialCells(xlCellTypeLastCell).Row 
'~~> rest of your code here 

如果您只有一（1）张工作表，您可以通过索引访问它。

Set mysh = wb.Sheets(1) 

您可能会发现这个有趣的POST其中讨论如何避免选择/激活/主动进一步提高您在未来的编码。 HTH。

这里是你的代码定制：

Sub RemoveEmptyRows() 
    Dim file_name As String 

    file_name = "C:\Users\Desktop\Workstation_A\Workbook_A.xlsm" 
    Dim i As Long 
    Dim LastRow As Long 

    Dim wb As Workbook, mysh As Worksheet 
    Set wb = Application.Workbooks.Open(file_name) 
    'Above code is same as yours 

    Set mysh = wb.Sheets(1) 'if only one sheet, use loop otherwise 

    Application.ScreenUpdating = False 
    Dim rngtodelete As Range 
    With mysh 
     LastRow = .Cells.SpecialCells(xlCellTypeLastCell).Row 
     'Collect all the range for deletion first 
     For i = LastRow To 1 Step -1 
      If WorksheetFunction.CountA(.Rows(i)) = 0 Then 
       If rngtodelete Is Nothing Then 
        Set rngtodelete = .Rows(i) 
       Else 
        Set rngtodelete = Union(rngtodelete, .Rows(i)) 
       End If 
      End If 
     Next i 
    End With 
    'Delete in one go 
    If Not rngtodelete Is Nothing Then rngtodelete.Delete xlUp 
    Application.ScreenUpdating = True 
End Sub 

Answer 2

工作表是.select，工作簿是.activate。

尝试

.Sheets(sheet_name).Select 

，而不是在一个时间删除行我会建议你建立一个字符串或范围，只是一个批量删除结尾。这里是设置你的方式为例：

Sub delete_rows() 
Dim MyRows As String 
For i = 27 To 1 Step -1 
    If WorksheetFunction.CountA(ActiveSheet.Rows(i)) = 0 Then 
     MyRows = MyRows & "$" & i & ":$" & i & "," 
     'wb.ActiveSheet.Rows(i).EntireRow.Delete 
    End If 
Next i 
MyRows = Left(MyRows, Len(MyRows) - 1) 
Range(MyRows).Delete 
End Sub
