CreateObject("Excel.Application") Failure

Hello,
Using VBA in Access 2007, I'm trying to create an Excel workbook with 2 sheets. The first sheet is created from a query, the second sheet "Result" requires a lot of formatting.
The problem is that the second sheet does not get created, the following code executes from the Event Procedure of a button:
Private Sub Command0_Click()
On Error GoTo errHdl
Dim xlApp As Object, path As String, fileName As String
Dim xlWB As Object, xlWS As Object, xlRes As Object
Dim lst As Integer, ctr As Integer, arr() As String, arrCtr As Integer, arrObj() As String
arrCtr = 0

start:
Set xlApp = CreateObject("Excel.Application")

path = Mid(CurrentDb.Name, 1, InStrRev(CurrentDb.Name, "\"))

If radAll.Value = -1 Then
fileName = "All Clients"
DoCmd.TransferSpreadsheet acExport, acSpreadsheetTypeExcel9, "qryAcct_Pos_All_Client", path & fileName & ".xls", True
Else
fileName = cmbClient.Value
DoCmd.TransferSpreadsheet acExport, acSpreadsheetTypeExcel9, "qryAcct_Pos_Client", path & fileName & ".xls", True
End If

xlApp.Visible = True
xlApp.workbooks.Open path & fileName & ".xls"

If radAll.Value = -1 Then

Set xlWB = xlApp.workbooks(fileName)
Set xlWS = xlWB.Worksheets("qryAcct_Pos_All_Client")

If radAll.Value = -1 Then
With xlApp
.workbooks(fileName).Worksheets.Add After:=xlApp.Worksheets(1)
.activesheet.Name = "Result"
.workbooks(fileName).Worksheets(1).Select
End With

lst = xlApp.worksheetfunction.counta(xlWS.Range("A:A")) - 1

Open in new window


Then there is a lot of formatting that I won't bore you with, ending with:
xlWB.Save
xlApp.screenupdating = True

Set xlApp = Nothing

Exit Sub
errHdl:
If Err.Number = 1004 Then
k = MsgBox("All Clients file already exist in the folder. Do you want to replace it", vbYesNo)
If k = 6 Then
xlWB.Close False
Kill path & fileName & ".xls"
GoTo start
ElseIf k = 7 Then
xlWB.Close False
Exit Sub
End If
End If
End Sub

Open in new window

The code creates the 'qry' sheet correctly and then the Excel window pops-up but without the second 'Result' sheet.
 No error is thrown.
I appreciate any help,
Thanks

What is radAll and what's it's value?

Have you tried stepping through the code with F8 and checking what's happening?

Is the code to add the worksheet actually being executed?

radAll is a radio checkbox and its value is -1.
The workbook 'All Clients.xls' is created with one sheet, 'qryAcct_Pos_All_Client'.

xlApp.Visible = True
xlApp.workbooks.Open path & fileName & ".xls"

If radAll.Value = -1 Then  

Open in new window

     
(The code stops working here)

When it stops working what's happening with Excel?

Also, are there any error messages?

PS Why are you checking radAll multiple times?

When the code stops, an Excel window pops-up displaying the 'All Clients' workbook and showing the only sheet.

There are no error messages.

I tried to eliminate the number of times the code checked for radAll values but it didn't make any difference. The workbook still only printed with one sheet.

Here's the order to open and close Excel:

    Dim xls     As Excel.Application
    Dim wkb     As Excel.Workbook
    Dim wks     As Excel.Worksheet
   
    Set xls = New Excel.Application
    Set wkb = xls.Workbooks.Open("c:\test\workbook1.xlsx")
    Set wks = wkb.Worksheets(1)
   
    wks.Name = "My New Name"
    wkb.Close True
   
    Set wks = Nothing
    Set wkb = Nothing
   
    xls.Quit
   
    Set xls = Nothing

You _MUST_ be very specific to this. If you set your xlApp to Nothing, its feet are kicked away.

Also, this won't Work:

With xlApp
.workbooks(fileName).Worksheets.Add After:=xlApp.Worksheets(1)
.activesheet.Name = "Result"
.workbooks(fileName).Worksheets(1).Select
End With

It should look like:

Set xlWB = xlApp.WorkBooks(fileName)
Set xlWS = xlWB.WorkSheets("qryAcct_Pos_All_Client")

Set xlWSnew = xlWB.WorkSheets.Add After:=xlWB.Worksheets(1)
xlWSnew.Name = "Result"
xlWB.WorkSheets(1).Select

etc.
Always state the explicit object, and always open and close carefully.

Further, except if you wish to view the formatting etc. taking place, there's no reason to Select anything, neither to make Excel visible - it only slows things down.

I am with @cactus_data on this one, I think the organization of your sub plays into a bit of your problems.

I'd get the xlApp,  xlWB  and xlWS  declared and set FIRST
I'd then walk through adding the additional sheets you want
Set xlWS = obook.Worksheets.Add
osheet.Move After:=obook.Worksheets(3) 'or whatever number

Open in new window

Once you have your sheets, add data to them
Being an Access guy, I like
Dim db as database
Dim rs as recordset
Set db = Currentdb
Set rs = db.OpenRecordset("Some SQL string, or the name of a saved query",dbOpenDynaset, dbSeeChanges)
xlWS.Range("A2").CopyFromRecordset rs

Open in new window

much better than TransferSpreadsheet, but your mileage may vary

Add data to each sheet in turn
Then format each sheet in turn.

You may find that when you think about re-factoring your code, you could break it into chunks: a sub to create the workbook and add the required sheets, a sub to add data to the sheets, and a sub to format the sheets.

It might be more maintainable and easier to read and de-bug
