how to know if loop contains a fixed number of iterations

[bullfrog83]

According to the thread "For...Next vs Do...Loop, and the Winner is?" you should use a For...Next loop if it has a fixed number of iterations and doesn't contain any logical conditions. This may be a dumb question but how do I know if my loop contains a fixed number of iterations? The majority of my loops consist of opening a recordset with a string expression equating to a query. Example:

        strRstClass = "SELECT C.* FROM StdDegReqClass C INNER JOIN StdDegReqDisc D ON C.StdDegReqDiscId = " _
                    & "D.StdDegReqDiscId WHERE C.StdDegReqDiscId = " & lngDiscId & " ORDER BY C.SortOrder"
        Set rstClass = CurrentDb.OpenRecordset(strRstClass, dbOpenSnapshot)
 

or

Set rstDegReqDisc = CurrentDb.OpenRecordset("SELECT * FROM DegReqDisc WHERE DegReqId = " & lngDegReqId, dbOpenSnapshot)
 

The recordset type is always Snapshot. (If I do any updating/deleting I usually do a CurrentDb.Execute "UPDATE...", not on the recordset.) I want to loop through the recordset until EOF or until another condition is met if not at EOF. Here's an example of a For...Next loop that I have that illustrates this:

        For intClass = 0 To rstClass.RecordCount
 
            If rstClass.EOF Then
                Exit For
            End If
 
            If sngDiscCredits >= rstDisc!CreditMin And lngDiscCourses >= rstDisc!CourseMin Then
                lngTakenDiscId = lngDiscId
                Exit For
            End If
 
            'more code....
            rst.MoveNext
        Next
 

So, from what I described, which looping structure should I use?

Personally, this is the Looping Structure that I always use and find to be very concise, and efficient:

'The Recordset rst has previously been defined
 
With rst
  Do While Not .EOF
    'processing example
    Debug.Print ![FirstName] & " " & ![LastName]
      .MoveNext
  Loop
End With
 
rst.Close
Set rst = Nothing
