我在Access 2007数据库中有一些VBA代码,用于将数据导出到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(这些行已经在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,那么它会自动显示,无论如何都会解决问题。但无法看到我在哪里/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

您的代码包含许多对Worksheets
和Ranges
的不合格且部分限定的引用。这些将引用ActiveWorkbook
或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
GetLastRow wbAllData.Worksheets("MainSheet").Columns("A")
