If your query uses parameters,you put it in code with:
Set qdf= currentdb.querydefs("qsMyQuery")
Qdf.parameters(0)="myCriteria"
Qdf.parameters(1)="myOtherCrit"
Set rst=qdf.openRecordset
 
Hi,

Usually this can mean that you have a spelling mistake in one of the the field names of an SQL statement

However, if you are passing a saved query, then you will need to resolve the criteria.

You can use the Leigh's Generic Recordset() function to open your recordset.

You would substitute the following line in your code:
Code:
' ...
'  Set rs = CurrentDb.OpenRecordset(strTable, dbOpenSnapshot)
  Set rs = fDAOGenericRst(strTable, dbOpenSnapshot)
' ...

As an alternative to all the code you have written to create a tab-delimited file, you can utilise a neat trick of an ADODB recordset (GetString() method).

It would mean using the fADOGenericRst() for the link I posted above. Here is version modified to be late bound, so you don't have to set a reference:
Code:
Function fADOGenericRst(ByVal strSource As String, _
                        Optional cnn As Object, _
                        Optional pCursorLocation As Integer = 2, _
                        Optional pCursorType As Integer = 1, _
                        Optional pLockType As Integer = 3, _
                        Optional pOption As Integer = -1) As Object

  Dim cmd As Object
  Dim prm As Object

  Set cmd = CreateObject("ADODB.Command")
  Set prm = CreateObject("ADODB.Parameter")

  If cnn Is Nothing Then
    Set cnn = CurrentProject.Connection
  End If

  Set cmd.ActiveConnection = cnn

  If Left(strSource, 11) <> "PARAMETERS " And Left(strSource, 7) <> "SELECT " Then
    strSource = "SELECT * FROM [" & strSource & "]"
  End If

  cmd.CommandText = strSource
  'cmd.Parameters.Refresh 'Is implicit - this is a Jet util so doesn't incur
  'overhead penalties
  For Each prm In cmd.Parameters
    prm.Value = Eval(prm.Name)
  Next

  Set fADOGenericRst = CreateObject("ADODB.Recordset")
  With fADOGenericRst
    .CursorLocation = pCursorLocation
    .Open cmd, , pCursorType, pLockType, pOption
  End With

  Set prm = Nothing
  Set cmd = Nothing

End Function

Then, you can reduce your code to:
Code:
Public Sub DataToText(ByVal strTable As String, _
                      Optional ByVal strOutput As String, _
                      Optional ByVal strDelimiter As String, _
                      Optional ByVal strRecBreak As String = vbNewLine, _
                      Optional ByVal bolExtaSpaceAbove As Boolean)
On Error GoTo ErrHandler

  Const adSaveCreateOverWrite = 2
  Dim i As Integer, strRecs As String
  
  DoCmd.Hourglass True
  If strOutput = "" Then strOutput = CurrentProject.Path & "\Text.txt"
  If strDelimiter = "" Then strDelimiter = Chr(9)
  With fADOGenericRst(strTable)
    For i = 0 To .Fields.Count - 1
      strRecs = strRecs & strDelimiter & .Fields(i).Name
    Next i
    strRecs = Mid(strRecs, Len(strDelimiter) + 1) & strRecBreak & _
              IIf(bolExtaSpaceAbove, strRecBreak, vbNullString)
    strRecs = strRecs & .GetString(, , strDelimiter, strRecBreak)
    .Close
  End With
  With CreateObject("ADODB.Stream")
    .Charset = "utf-8"
    .Open
    .WriteText strRecs
    .SaveToFile strOutput, adSaveCreateOverWrite
    .Close
  End With
  
Resume_Here:
  DoCmd.Hourglass False
  Exit Sub
  
ErrHandler:
  DoCmd.Hourglass False
  If Err.Number = 70 Then
    MsgBox "Error: " & Err.Number & vbCrLf & vbCrLf & _
            "Cannot create " & strOutput & "." & vbCrLf & _
            "Make sure you have sufficient right."
  Else
    MsgBox Err.Number & ": " & Err.Description
  End If
  Resume Resume_Here
  
End Sub
