Question

Recordset Clone in Access2003 ADP connected to SQL 2005

Asked by: afsfire

I am simply trying to have a the result selected from a Combo box post to this form. I had it working in an mdb (see mdb code ) and tried to translate it to ADO (see adp code) however it is not quite right.

mdb Code
Private Sub cboCompany1_AfterUpdate()
    ' Find the record that matches the control.
    Dim rs As Object
 
    Set rs = Me.Recordset.Clone
    rs.FindFirst "[ID] = " & Str(Nz(Me![cboCompany1], 0))
    If Not rs.EOF Then Me.Bookmark = rs.Bookmark
End Sub
 
ADP Code
 
Private Sub cboCompany1_AfterUpdate()
Dim rs As Object
Set rs = Me.Recordset
    rs.MoveFirst
    rs.Find "[ID] = " & Str(Nz(Me![cboCompany1], 0))
    If rs.EOF Then Exit Sub
    
    Me.Bookmark = rs.Bookmark
End Sub

Hi

In what way doesn't it work? i.e. What error if there's an error or what behaviour is manifested?

The code you're using isn't exactly the wizard generated code in an ADP.
The most crucial difference is that you're refering to the form's Recordset property. You're not creating a clone or working with the form's own clone.

What you would normally have instead would be

Private Sub cboCompany1_AfterUpdate()
Dim rs As Object
Set rs = Me.Recordset.Close '<<<<< ---- This line here
   rs.Find "[ID] = " & Str(Nz(Me![cboCompany1], 0))
   If rs.EOF Then Exit Sub
   Me.Bookmark = rs.Bookmark
End Sub

This makes it a bit closer to the MDB created equivalent.
The reason for this is that a new Clone (which is what's created by the .Clone method) will be distinct from the form's own recordset. It will be position on the first row and the Find method will search from there. (The default should be the Current Row - but in a form's own recordset - you may or may not see consistent behaviour). The MoveFirst should guarantee that you code worked - when you're working with the form's recordset as you are then the Bookmark line is unnecessary.
i.e. this should still have worked for you

Private Sub cboCompany1_AfterUpdate()
Dim rs As Object
Set rs = Me.Recordset
   rs.MoveFirst
   rs.Find "[ID] = " & Str(Nz(Me![cboCompany1], 0))
End Sub

or even

Private Sub cboCompany1_AfterUpdate()
   Me.Recordset.Find "[ID] = " & Str(Nz(Me![cboCompany1], 0)), 0, adSearchForward, adBookmarkFirst
End Sub

The rest of the code is wizard standard, including the presupposition that "0" isn't a viable value in your records selection. (It's an Autonumber/Identity assumption that you'll have started from 1 and are unlikely to have come back to 0!)

If something specific is wrong then certainly spell it out.

Cheers.

And once you move away from recordset-oriented thinking from Access-oriented, it becomes

Private Sub cboCompany1_AfterUpdate()
    ServerFilter = "id=" & cboCompany1
    Requery
End Sub

that is,

from recordset-oriented thinking to Access-oriented

(since I'm now working with very similar design)

actually, the best solution, it appears, is to have unbound main form, and accordingly unbound field (combobox or textbox) where the user is making the entry to search for; the found data is displayed in the subform by means of the usual master field/child field; in this case, no code is required at all.

If search field is bound, it becomes hard to prevent changing the existing record to the entered value, instead of navigating to it - too many various scenarios.
