Remove Excel task from Task manager after running from Access using VBA - excel

Question

I will now take the opportunity to ask here, I have really tried a lot of different way, but it seems that I am not able to be able to close the Excel task in task-manger, It hangs until I close Access completely, annoying, because I can not run two different jobs using Excel from Access. Second job will give me errors.
I have made some comments to where I still is able to get rid of Excel.
The purpose for the code is to run some query's and export data to excel and then lock the excel sheet so users only can fill in answers to the data.
Code:
Private Sub Command65_Click()
Dim r As Double
'On Error GoTo Error_Handler
Dim objExcel As Excel.Application
Dim objWorkbook As Workbook
Dim objWorksheet As Worksheet
Dim dbs As DAO.Database
Dim rSt As DAO.Recordset
Set dbs = CurrentDb
Set rSt = CurrentDb.OpenRecordset("qry_VC_Confirmation")
Set objExcel = CreateObject("Excel.Application")
objExcel.Visible = True
'objExcel.Quit ' at this point it still works to close again
'Set objExcel = Nothing ' at this point it will remove from task manager
Set objWorkbook = objExcel.Workbooks.Add
Set objWorksheet = objWorkbook.Worksheets(1)
'Set objWorkbook = Nothing ' can close still at this stage
'Set objWorksheet = Nothing ' can close still at this stage
'objExcel.Quit ' at this point it still works to close again ?
'Set objExcel = Nothing ' at this point it still will not remove from task manager
iFld = 0
irow = 1
For icol = 1 To (rSt.Fields.count)
objWorksheet.Cells(irow, icol) = rSt.Fields(iFld).Name
objWorksheet.Cells(irow, icol).Interior.ColorIndex = 1
objWorksheet.Cells(irow, icol).Font.ColorIndex = 2
objWorksheet.Cells(irow, icol).Font.Bold = True
iFld = iFld + 1
Next
'Set objWorkbook = Nothing '
'Set objWorksheet = Nothing '
'objExcel.Quit ' at this point it still works to close Excel again ?
'Set objExcel = Nothing ' at this point it will still remove from task manager
irow = 2
If Not rSt.BOF Then rSt.MoveFirst
Do Until rSt.EOF
iFld = 0
lRecords = lRecords + 1
For icol = 1 To (rSt.Fields.count)
objWorksheet.Cells(irow, icol) = rSt.Fields(iFld)
iFld = iFld + 1
Next
irow = irow + 1
rSt.MoveNext
Loop
r = irow - 1
Columns("A:F").EntireColumn.AutoFit
ActiveSheet.Protection.AllowEditRanges.Add Title:="Unprotected", Range:=Range("F2:F" & r)
ActiveSheet.Protect DrawingObjects:=True, Contents:=True, Scenarios:=True, Password:="secret"
objWorkbook.SaveAs ("C:\Dropbox\VC_Confirmation.xlsx")
ExitSub:
Set objWorkbook = Nothing '
Set objWorksheet = Nothing '
objExcel.Quit ' at this point it still works to close excel again ?
Set objExcel = Nothing ' at this point it will **NOT** remove from task manager
Exit Sub
Error_Handler:
MsgBox Error$
Resume ExitSub
End Sub

Answer 1

In the comments you mentioned that you had reset your code (i.e. pressed the stop button). This means that the portion of your code that kills excel did not run, thus leaving an open session of excel. There is a small (possibly semantic) issue with your code, but I don't believe that's what was causing your issue. Regardless, you should properly shut down the application like this.
ExitSub:
If Not objWorksheet Is Nothing Then
set objWorksheet = Nothing
End If
' You have to check for the workbook's existence before
' you try to close something that isn't there. This avoids runtime errors.
' Since your error handler points you back here, this code always runs, so
' The workbook might not be open.
If Not objWorkbook Is Nothing Then
objWorkbook.close
Set objWorkbook = Nothing
End If
' Same goes for quitting the application
If Not objExcel Is Nothing Then
objExcel.Quit
Set objExcel = Nothing
End If
Exit Sub
Error_Handler:
' error handling code here
Resume ExitSub
End Sub

Columns("A:F").EntireColumn.AutoFit
Adding as an answer just in case. Fully qualify this with the worksheet name and try again. This same problem was a huge bother to me too. You have to qualify 100% of your references, no matter what. Also, be super careful about using With statements on ranges, worksheets etc. So change it to ObjWorksheet.Columns("A:F")... instead
