How to manage the "No current record" situation after a Form.Requery method

Hello,
I'm preparing a simple mask in Access 2003.
The RecordSource of this mask is a table named Persons, whose fields are "IDPerson" (counter field and primary key), "Name", "SecondName" and "Age".
In the mask there are some textboxes linked to the fields above, and there are the classical CommandButtons "btnAdd", "btnDelete" and, when I’m inserting a new record (by clicking on "btnAdd"), "btnSave" and "btnCancel".
At the end there is a "lstPersons" ListBox to select the desired record. It has as RowSource:
RowSource = "SELECT IDPerson, Name FROM Persons ORDER BY Name"
so it has 2 columns, the first one (that is also the one that gives the value to the ListBox) linked to "IDPerson" field (0 cm width, so invisible to the user), the second one linked to "Name" field.

The code of the lstPersons_AfterUpdate() event handler is very simple:

Code:

---

Private Sub lstPersons _AfterUpdate()

    Me.Recordset.FindFirst "IDPerson = " & lstPersons.Value

End Sub

---

The code of the btnAdd() is this one:

Code:

---

Private Sub btnAdd_Click()

    Me.AllowAdditions = True
    Me.Recordset.AddNew

End Sub

---

The code of the btnSave_Click() event handler is this one:

Code:

---

Private Sub btnSave_Click()

    Dim IDPerson As Long
   
    With Me
        IDPerson = Me.Recordset.Fields("IDPerson")
        DoCmd.RunCommand acCmdSaveRecord
        .Requery
       
        .Recordset.FindFirst "IDPerson = " & IDPerson
    End With
   
    Me.Refresh

End Sub

---

At the end I have prepared an "UpdateMaskControls" procedure that is called in the Form_Current() event handler, so, when the current record changes (because the user has selected another record in "lstPersons" or because he has clicked on "btnAdd" and then on "btnSave"), "UpdateMaskControls" code is executed:

Code:

---

Private Sub Form_Current()

    UpdateMaskControls
   
End Sub

---

The goal of the "UpdateMaskControls" is to show/hide the CommandButtons (if the record is new or not) and to select the correct value of "lstPersons" (in the case the user has added a new record):

Code:

---

Public Sub UpdateMaskControls ()

    With Me
       
        If .NewRecord Then
            .btnSave.Visible = True
            .btnCancel.Visible = True

            .btnAdd.Visible = False
            .btnDelete.Visible = False
        Else
            .lstPersons.Enabled = True
            .lstPersons.Value = .Recordset.Fields("IDPerson")

            .btnAdd.Visible = True
            .btnDelete.Visible = True

            .btnSave.Visible = False
            .btnCancel.Visible = False
        End If
       
    End With
   
End Sub

---

The problem is this one: when the user adds a new record and then clicks on “btnSave”, the Me.Requery statement (in btnSave_Click event handler) calls Form_Current event handler that calls UpdateMaskControls procedure, and when the statement:

Code:

---

.lstPersons.Value = .Recordset.Fields("IDPerson")

---

is executed, an error occurs (the reason is: no current record).
At the beginning I have thought that perhaps, after the Form Requery, the state of the Recordset is BOF or EOF, so at the top of UpdateMaskControls I have added the code:

Code:

---

If Me.Recordset.BOF Or Me.Recordset.EOF Then
        Exit Sub
End If

---

But I have realized that the Form Recordset is not BOF and not EOF.
I also tried to use the Me.CurrentRecord method (always at the top of UpdateMaskControls):

Code:

---

Dim l As Long
l = Me.Recordset.Fields("IDPerson")

---

to understand if its value could help me, but I have realized that, after the Form Requery, l = 1 (as the current record had been the first one)

How can I catch the "No current record" exception before executing the entire UpdateMaskControls code?

Thank you very much. Sorry for the length of the thread, but I have tried to be as clear as possible.

Before I address your issue, it would make life easier if you would
edit your post and wrap the several code snippets using the Code icon
at the top of the window.

Ok, now I have seen the Code icon and used it... Sorry

Thanks.. that helps alot.

I've read thru your OP twice, albeit rather quickly, and must confess
that I dont' quite get the picture yet. Gotta run for a bit, but will
look at it again a little later.

In the meantime, hopefully someone else will jump in.

Did you check to see if the below piece was successfull?

vb Code:

.Recordset.FindFirst "IDPerson = " & IDPerson
