how to loop through the records of a subform, VBA Access 2010

Question

Here's my question: i have a subform inside a main form. The main form contains the customer number, and the subform contains the order for that customer. So one customer may have multiple orders. I want to create a buttom which when clicked moves to the next order for that customer. I have no issue doing this with the code:

 Private Sub next_comp_Click()
 [Forms]![Customer]![Order Subform].SetFocus
 DoCmd.GoToRecord , , acNext
  end sub

where I have issues is when I get to the last order for that customer. I will like it to loop back to the first order. To do this i used this code:

Private sub next_comp_click()
[Forms]![Customer]![Compressor Subform].SetFocus
Dim dbcustomer As Database
Dim rstorder As Recordset

Set dbcustomer = CurrentDb
Set rstorder= dbcustomer.OpenRecordset("orders", dbOpenSnapshot)
  With rstEmployees
    If .AbsolutePosition = - 1 Then
    MsgBox (.RecordCount)
    'DoCmd.GoToRecord , , acFirst
    Else
    DoCmd.GoToRecord , , acNext
    End If
  End With
 end sub

I used the MsgBox function to kind of debug to figure what record I am on (ultimately I want it to loop back to the first record as shown in the commented out code), but for some reason, it tells me i am always on the first record, ie it tells me the RecordCount is 1. This is not supposed to be so because most of the records I am working with have multiple orders. If I change the condition to something like If .AbsolutePosition = 3, it moves the records to the next until i get to the last or empty record and if i click next from there, it gives me the run-time error '2105' you cannot go to the specified record.

I think the issue is the .AbsolutePositon property is not looking at the right form or table, but any answers will be much appreciated.

Thank you in advance.

Answer 1

You do not even need that recordset stuff if your forms are bounded. Just use the following code in the button:

Private sub next_comp_click()
   [Forms]![Customer]![Order Subform].SetFocus
   If [Forms]![Customer]![Order Subform].Form.CurrentRecord >= [Forms]![Customer]![Order Subform].Form.Recordset.RecordCount Then
       DoCmd.GoToRecord , , acFirst
   Else
       DoCmd.GoToRecord , , acNext
   End If
End sub

I built an access database to replicate this just to make sure the code was exact. You should be able to copy and paste this and it will work.

This is what I do to loop to the First record after hitting the last record. Put it in VBA. Just do the reverse if using a previous button.

 If Me.CurrentRecord = Me.Recordset.RecordCount Then
       DoCmd.GoToRecord , , acFirst
   Else
       DoCmd.GoToRecord , , acNext
   End If
