Question

Is it possible to change the Openargs values once the form is already open in Access? It works only the first time the form is open. It fails of the form is open already.

EDIT:

I have this code in the onActivate event of the form

If Not IsNull(Me.OpenArgs) Then
    Me.Recordset.FindFirst ("Id =" & Me.OpenArgs)
    If Me.Recordset.NoMatch Then
        MsgBox "ISOS not found"
    End If
End If

Me.OpenArgs contains the result of a search in another form that uses this command DoCmd.OpenForm "<Form_Name>", acNormal, , , , acWindowNormal, Forms!Lookup_Form!Id to open up the main form.

How about running your code from the search form, like so:

Dim frm As Form

If Not CurrentProject.AllForms("Form1").IsLoaded Then
    DoCmd.OpenForm "Form1"
End If

Set frm = Forms!Form1
frm.Recordset.FindFirst ("Id =" & Me.ID)
If frm.Recordset.NoMatch Then
    MsgBox "ISOS not found"
End If
