For Each Loop works once then gives error 91

For Each Loop works once then gives error 91

For Each Loop works once then gives error 91

(OP)
Upfront, letting you know I might not have explained well or need to provide more code for context...

This question is using MS-Access to run vba to modify an excel sheet.

Found this code to refresh data in pivot at https://www.automateexcel.com/vba/refresh-pivot-ta...

It seems to work fine without error the first time I run it. Normally I only have to run the code once and only discovered the issue when doing some testing to adjust other things in the spreadsheet unrelated to the pivot, when I click the button to run the code a second time, it stops on this line with the error.

Run-time error 91 Object or variable with block not set

CODE --> 

Case "Submittal Data"
                    .Cells(2, 1).CopyFromRecordset rs
                    For Each chPivot In ActiveWorkbook.PivotCaches
                        chPivot.Refresh
                    Next chPivot
                    .Range("H2:H" & lastRow + 1).ClearContents
            End Select

This code is only run one time per click and I finish it off by setting things to nothing.
If I completely close/exit MS-Access and reopen it. It is fine again to run once, but not more than once before the error happens.

RE: For Each Loop works once then gives error 91

What do you get when you add a line in the code:

MsgBox ActiveWorkbook.PivotCaches.Count
For Each chPivot In ActiveWorkbook.PivotCaches

You may also check if you refer to proper workbook before refreshing the cache:
MsgBox ActiveWorkbook.Name

combo

RE: For Each Loop works once then gives error 91

If this is your code from Access, you (should) have some code above to reference an Excel object, right?

CODE

With xlApp
    ...
    .Cells(2, 1).CopyFromRecordset rs
    ...
End With

This is weird with Excel.
If you have this in your code: Cells(2, 1). (See the missing period before Cells?), Excel will let you run it first time just fine, but then complains about the code you have just run. Nice.

So, I would check how you declared chPivot, and fully qualify it.

combo, first time through:
Debug.Print ActiveWorkbook.Name displays: SubmittalsOverdueDataLeadChart_Template.xlsx
Debug.Print ActiveWorkbook.PivotCaches.Count displays: 1

second time error 91 when it gets to the debug statement

CODE --> 

Case "Submittal Data"
                    .Cells(2, 1).CopyFromRecordset rs
                    Debug.Print ActiveWorkbook.Name
                    Debug.Print ActiveWorkbook.PivotCaches.Count
                    For Each chPivot In ActiveWorkbook.PivotCaches
                        chPivot.Refresh
                    Next chPivot
                    .Range("H2:H" & lastRow + 1).ClearContents
            End Select

RE: For Each Loop works once then gives error 91

You are worrking in Access, yes?

In that case, I am surprised that

ActiveWorkbook.PivotCaches (or trying to access anyu other properties or methods of ActiveWorkbook)

works at all!

Unless, of course, you have a global object declared as ActiveWorkbook somewhere else, are assigning it to an excel application's ActiveWorkbook, and is being referenced and dereferenced elsewhere.


You'd be best off in the short term to be explicxit, and use

objapp.ActiveWorkbook

In the long run, see if you can hunt down the declaration and usage of ActiveWorkbook with a view to eliminating it if you can; this is a great example of why global variables are to be used sparingly

RE: For Each Loop works once then gives error 91

You don't need ActiveWorkbook in your function. After Set wb = objapp.Workbooks.Open(filename, True, False) you can work directly with wb, so:
For Each chPivot In wb.PivotCaches.

I guess that you have reference to Excel (so why excel objects and constants work). You may benefit from early binding, for instance:
Dim objapp As Excel.Application
Dim wb As Excel.Workbook
Dim ws As Excel.Worksheet
Dim Rng As Excel.Range
Set objapp = New Excel.Application

combo

RE: For Each Loop works once then gives error 91

sxschech does have an early binding to Excel. Otherwise the declaration:
Dim chPivot As PivotCache
would error.

So, we have here combination of early and late binding, but why?

And nowhere in the code I can see:

CODE

With objapp
    ...
End With
to explicitly reference Excel object.
That's why, in my opinion, Excel is saying: I will let you pass once, but after that - an error.
Happened to me many times.

RE: For Each Loop works once then gives error 91

Here's an illustyration of what I think is happening (and early or late binding makes no difference):

CODE --> 

Option Compare Database
Option Explicit

Public ActiveWorkbook As Object

' Early or late binding makes no difference to this
Public Sub Demo()
    Set ActiveWorkbook = CreateObject("Excel.Application").workbooks.Add ' possibly in some startup code somewhere, so only run once
       
    minimalexample
    
    ActiveWorkbook.Close
    Set ActiveWorkbook = Nothing ' possibly in some cleanup code, but this can be run multiple times without error, so could happily sit ion your main processing loop
    
    minimalexample
     
End Sub

Public Sub minimalexample()
    Dim objapp As Object
    Set objapp = CreateObject("Excel.Application")
    Debug.Print ActiveWorkbook.Name
End Sub

RE: For Each Loop works once then gives error 91

Quote (sxschech)

second time error 91 when it gets to the debug statement

Try:

CODE

Case "Submittal Data"
    .Cells(2, 1).CopyFromRecordset rs
    Debug.Print objapp.ActiveWorkbook.Name
    ...

---- Andy

"Hmm...they have the internet on computers now"--Homer Simpson

RE: For Each Loop works once then gives error 91

The error is because of Excel is not an active window. Tested in Word VBA with reference to Excel:

CODE --> 

Sub test()
Dim objExcel As Object
Set objExcel = CreateObject("Excel.Application")
objExcel.Visible = True
objExcel.Workbooks.Add
' Application.Activate
MsgBox ActiveWorkbook.Name
objExcel.Quit
Set objExcel = Nothing
End Sub
The code works, Word displays workbook name (under Excel window on top). If Application.Activate is uncommented, Word is on top, code breaks with run-time error 91.

combo

RE: For Each Loop works once then gives error 91

combo,

Your code gives "Variable not defined" error on line:
MsgBox ActiveWorkbook.Name
It needs:
MsgBox objExcel.ActiveWorkbook.Name

---- Andy

"Hmm...they have the internet on computers now"--Homer Simpson

RE: For Each Loop works once then gives error 91

Andy, do you have Excel referenced? ActiveWorkbook is in the library, so should be recognised.

combo

RE: For Each Loop works once then gives error 91

No, I do not have Excel referenced, since your code refers to a late binding (I guess)

With an early binding (Excel referenced), I would expect to see:
Dim objExcel As New Excel.Application

"Hmm...they have the internet on computers now"--Homer Simpson

RE: For Each Loop works once then gives error 91

(OP)
Wow, great discussion. Thanks for the input.

Andy, looks like your last post sorted it out. After adding objapp. before ActiveWorkbook, I was able to run the code multiple times without the error.

I did a search [CTRL+F] for Current Project and that was the only spot where ActivWorkbook exists, so my thought is that it only affected that one item...unless as Andy mentioned there are other statements that should be prefixed with objApp or use

Quote (Andy)

With objapp
...
End With

Sometimes hard for me to discern which statements need more prefixes (excuse if terminology not correct) between native excel vba and running excel code indirectly via access vba.

Revised code in green

CODE --> 

Case "Submittal Data"
    .Cells(2, 1).CopyFromRecordset rs
    Debug.Print objapp.ActiveWorkbook.Name
    Debug.Print objapp.ActiveWorkbook.PivotCaches.Count
    For Each chPivot In objapp.ActiveWorkbook.PivotCaches
        chPivot.Refresh
    Next chPivot
    .Range("H2:H" & lastRow + 1).ClearContents
End Select

Regarding early/late binding, yes I have both because in the beginning I used early binding and then down the road tried to switch to late binding and then sometimes copied bits and pieces from older code or the web to get things working and so things got a bit muddled.

RE: For Each Loop works once then gives error 91

Looks like my screen refreshed whilst I was clicking on the post, meant to star Andy's post from 29 Aug 23 14:53 rather than 29 Aug 23 18:18 which must have come in while preparing and reviewing my reply.

Quote (sxschech)

Regarding early/late binding, yes I have both

it is kind of tricky to switch, unless you have a way to fully compile your code and assure you do have Option Explicit
With an early binding, all Excel's constants like xlNone, xlDiagonalDown, xlEdgeBottom, xlContinuous, etc. will work just fine. But as soon as you change to a late binding (and eliminate reference to Excel), you may crash all over unless you change all of those constants to -4142, 5, 9, 1 respectively.

I need the reference to Excel even with late binding, as I use ActiveWorkbook in the code. There is no ActiveWorkbook when Excel is not active, so run-time error 91.

RE: For Each Loop works once then gives error 91

(OP)
Contributing a new line of code before the refresh since I figured out how to adjust the range of the pivot table due to the latest refresh having less rows than the template and that caused the chart to display a literal blank. This is a hard coded statement per the comments, so it would need to be modified if dealing with multiple pivot charts or if the sheet containing the pivot is on another tab.

CODE --> 

'Adjust the range for the pivot table and refresh
    'Since this is from an excel file being used like a template, we know there is only
    'one pivot table as well as the sheet and range which
    'is why that is hard coded in the replace statement as R663
    'otherwise, would need to further identify the sheet, the
    'pivottable name and the range in order not to change the
    'source data of multiple pivots.  
'Found the range via chPivot.SourceData
    '20230829
    For Each chPivot In objapp.ActiveWorkbook.PivotCaches        
        chPivot.SourceData = Replace(chPivot.SourceData, "R663", "R" & lastRow)
        chPivot.Refresh
    Next chPivot

RE: For Each Loop works once then gives error 91

>After adding objapp. before ActiveWorkbook

Something I advised way back near the beginning ...

RE: For Each Loop works once then gives error 91

(OP)
strongm, sorry for the oversight, you are correct. <smiley>ashamed icon</smiley> I think due to the additional discussions and examples, it didn't register that you provided the original solution. Hopefully it is rectified by the star. If not, please advise.
