Access listbox's rowsource: error Too many line continuations

Experts:

I need assistance with fixing a VBA error "Too many line continuations".

In a form, I'm using a listbox which row source is shown in the code below.   Ideally, I'd like to display 42 values in the listbox.   It appears there a limit to the menu options (based on the line break ' & _ ').   That is, once I keep on adding additional row source values, the VBA error is thrown.

How can this be fixed?   Thanks!

Me.ListBox.RowSource =  "Q01;" & _
                                              "Q02;" & _
			                      "Q03;" & _
			                      "Q04;" & _

wha t if you do it like this

Me.ListBox.RowSource =  "Q01;Q02;Q03;Q04;Q05;" & _
                              "Q06;Q07;Q08;Q09;Q10;" & _
                              "Q11;Q12;Q13;Q14;Q15;" & _
                              "Q16;Q17;Q18;Q19;Q20;" & _
                              "Q21;Q22;Q23;Q24;Q25;"

Or you could use something like:

For intLoop = 1 to 25
    strSource = strSource & ";Q" & Format(intLoop, "00")
Next
me.listbox.RowSource = Mid(strSource,2)

You would use a callback function for this:
Public Function ListNumbers( _
  ctl As Control, _
  lngId As Long, _
  lngRow As Long, _
  lngCol As Long, _
  intCode As Integer) As Variant
  
  Dim varValue      As Variant

  Select Case intCode
    Case acLBInitialize
      varValue = True             ' True to initialize.
    Case acLBOpen
      varValue = Timer            ' Autogenerated unique ID.
    Case acLBGetRowCount          ' Get rows.
      varValue = 42               ' Set number of rows.
    Case acLBGetColumnCount       ' Get columns.
      varValue = 1                ' Set number of columns.
    Case acLBGetColumnWidth       ' Get column width.
      varValue = -1               ' Use default width.
    Case acLBGetValue             ' Get the data.
      varValue = Format(lngRow + 1, "\Q00")
    Case acLBGetFormat            ' Format the data.
      ' varValue = strFormat
    Case acLBEnd
      ' Do something when form with listbox closes or
      ' listbox is requeried.
  End Select
  
  ' Return Value.
  ListNumbers = varValue

End Function

Now, set for the ListBox the property:

  RowSourceType: ListNumbers

Thanks... it looked like a very promising approach.   However, based on the approach (for which you assisted me last week), it won't work.

That is, in the ListBox_AfterUpdate() event, I'm using the following code as part of a strGenericField.

So, if the VBA is written as "Test Issue Q01; Test Issue Q02; Test Issue Q03; Test Issue Q04; Test Issue Q05;" & _"

then in the AfterUpdate event, the following line of code doesn't find the field (parameter error).

       Select Case Me.ListBoxStatistics
            Case "Test Issue Q01": strGenericField = "Q01"
            Case "Test Issue Q02": strGenericField = "Q02"
            etc. etc.

Dale -- I'm checking out your solution right now.    Based on the above response, it may not work either... 'didn't anticipate this domino effect.

Sorry... your proposed version probably would work under different conditions.   I thought I'd streamline the menu options (in the example posting).

However, the rowsource value do differ quite a bit.   For example, I also include a reference to test issues.   The next two lines show an actual example.

    Me.ListBoxStatistics.RowSource = "Test sub-issue '1.1.1.1' (Q07);" & _
                                                                 "Test sub-issue '1.1.2.1' (Q09);" & _
                                                                 etc. etc.

Gustav -- thanks for chiming in... previous comment appears to apply to your recommendation as well.  Again, I didn't anticipate the trickle-down effect.

Well, how could we know?
May I suggest you list your full requirements, not bit by bit.

I understand... as mentioned before, I didn't anticipate the secondary effect.   I'll split up the test issues into 4 different listboxes.   Not ideal (with respect to maintenance) but not big deal.

Thanks for chiming in... I know your solution would have worked otherwise.
