我在 Access 2007 数据库中有一些 VBA 代码，可将数据导出到 Excel 2007 文件。我对这段代码有疑问：

Sub GetLastRow(strSheet, strColum)
Dim MyRange As Range
Dim lngLastRow As Long

Set MyRange = Worksheets(strSheet).Range(strColum & "1")

lngLastRow = Cells(65536, MyRange.Column).End(xlUp).Row
lngLastRow = lngLastRow + 1
Rows(lngLastRow & ":1048576").Select

Selection.Delete Shift:=xlUp
End Sub

问题是变量 lngLastRow 不计算属于 excel 文件中的标题行（这些已经在 excel 文件中），除非我手动打开 Excel 会话然后继续运行代码。我想正确解决这个问题，但至少如果我可以包含一些代码来显示 excel 文件，这样它就会自动出现，无论如何都会解决这个问题。但看不到我在哪里/如何做到这一点。

以下是调用上述函数的函数。

Function CreateExcelData()
'Copies data to be exported to an Excel workbook
Dim objExcel         As Excel.Application
Dim strTemplate      As String
Dim strPathFile      As String
Dim RowCount         As Integer
Dim wbExported       As Workbook  'The initial exported data
Dim wbAllData        As Workbook   'Workbook to copy exported data to
Dim rngUsed          As Range        'Used range in exported data
Dim Sheet            As Worksheet

'Try GetObject first in case Excel Application is already open.
On Error Resume Next
Set objExcel = GetObject(, "excel.Application")
If Err.Number <> 0 Then
    'GetObject returns error if not already open
    'so use CreateObject
    On Error GoTo 0 'Turnoff ASAP so error trapping is available
    Set objExcel = CreateObject("Excel.Application")
End If

strTemplate = "TEMPLATE.xlsm"
strPathFile = strPath & strTemplate
strPathFileFinal = strPath & strReportName & "_" & Mydat & ".xlsm"

FileCopy strPathFile, strPathFileFinal

'Open the exported data workbook and assign to a variable
Set wbExported = objExcel.Workbooks.Open(strFilePath)

'Open the data workbook to receive the exported data and assign to a variable.
Set wbAllData = objExcel.Workbooks.Open(strPathFileFinal)

'Exported data 
With wbExported.Sheets(1).UsedRange
    Set rngUsed = .Offset(1, 0) _
        .Resize(.Rows.Count - 1, .Columns.Count)
End With

With wbAllData.Sheets("MainSheet")
    'Copy exported data and paste to first empty cell of MainSheet in File
    rngUsed.Copy
    .Cells(Rows.Count, "A").End(xlUp).Offset(1, 0).PasteSpecial Paste:=xlPasteValues
End With

Call GetLastRow("MainSheet", "A")

wbExported.Close

wbAllData.Save
wbAllData.Close

Set rngUsed = Nothing
Set wbExported = Nothing
Set wbAllData = Nothing
Set objExcel = Nothing

Kill strFilePath

End Function

您的代码有许多对 和 的非限定和部分限定Worksheets引用Ranges。这些将引用ActiveWorkbookor ActiveSheet，可能不是您想要的，并且会导致不可预测的结果。

试试这个重构

Sub GetLastRow(MyRange As Excel.Range)
    Dim lngLastRow As Long

    With MyRange.Worksheet
        lngLastRow = .Cells(.Rows.Count, MyRange.Column).End(xlUp).Row
        .Range(.Cells(lngLastRow + 1, 1), .Cells(.Rows.Count, 1)).EntireRow.Delete
    End With
End Sub

像这样称呼它

GetLastRow wbAllData.Worksheets("MainSheet").Columns("A")
