Access 2007 vba to find last row in Excel 2007 worksheet - excel

Question

I have some VBA code within an Access 2007 database that exports data to an Excel 2007 file. I have a problem with this piece of the code:
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
The issue is the variable lngLastRow does not count belong the header rows (these are already in the excel file) in excel file unless I manually open the Excel session and then continue running the code. I would like to solve this correctly, but as a minimum if I could include some code to display the excel file so it appears automatically that would solve the issue anyway. But can't see where/how I could do this.
The following is the function that calls the above function.
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

Your code has a number of unqualified and partially qualified references to Worksheets and Ranges. These will refer to the ActiveWorkbook or ActiveSheet, probably not wjhat you want, and will cause unpredictable results.
Try this refactor
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
Call it like this
GetLastRow wbAllData.Worksheets("MainSheet").Columns("A")
