Reference Form Fields Value - Application-defined Error 2465

[jbrumbau]

Hello,

I am trying to refer to fields on a given form from the form query's recordset, essentially from the following commands:

    Dim frm As Form 'Refers to the current form
    Dim tagName As String 'Refers to the field in the form's recordset (not a control on the form)
 
    ...
    frm.Fields(tagName).Value 'This gives Error 2465
 

My question is how do I refer to a field in the form's record set (not an individual control on the form)? If I use frm![LineTag].Value, it works fine, but frm.Fields(tagName).Value does not. Conversely, rs.Fields(tagName) does work fine. (note: tagName="LineTag")

Please let me know how I can refer to a form's recordset field.

Thanks!

...
For more info and as to why I need it, here is a large chunk of the function I use to call the segments mentioned above:

Function duplicateRecord(ByRef frm As Form, tableName As String, uniqueCtl As TextBox, tagName As String, ByRef avarExceptionList() As String) As Long     Dim rsExist As Recordset
    Dim keyName As String, keyValue As Long
    Dim tempRecord As Long
    Dim fld As Field
 
On Error GoTo Err_duplicateRecord
    Set rsExist = CurrentDb.OpenRecordset(tableName)
    keyName = uniqueCtl.ControlSource
    If uniqueCtl.Value > 1 Then
        keyValue = uniqueCtl.Value
        If frm.NewRecord Then
            Call MsgBox("New records cannot be duplicated, please save this record first then try again.", vbExclamation, "Nonexistant Record")
            duplicateRecord = -1
            Exit Function
        ElseIf frm.Dirty Then  
            If MsgBox("Save changes?", vbYesNo, "Unsaved Changes Detected") = vbYes Then
                MsgBox frm.Fields("LineTag")  
                If isSaveable(tableName, tagName, frm.Fields(tagName).Value, keyName, keyValue) Then 'This gives Error 2465  
                    Call saveRecord(frm, keyValue)  
                Else
                    Exit Function
                End If
            Else
                Exit Function
            End If
        End If
    ...
End Function

I'm actually a little confused about your question, but to Output a List of Fields comprising a Form's Recordset:

Dim rst As DAO.Recordset
Dim fld As DAO.Field
 
Set rst = Me.RecordsetClone
 
For Each fld In rst.Fields
  Debug.Print fld.Name
Next

Sample Output:

EmployeeID
LastName
FirstName
MI
Title
TitleOfCourtesy
BirthDate
HireDate
Address
City
Region
PostalCode
Country
HomePhone
Extension
Photo
Notes
ReportsTo

To actually refer to Fields within the context of a Form's Recordset, once it has been defined:

rst!EmployeeID
rst!LastName
rst!FirstName
rst!MI
rst!Title
rst!TitleOfCourtesy
rst!BirthDate
rst!HireDate
rst!Address
rst!City
rst!Region
rst!PostalCode
rst!Country
rst!HomePhone
rst!Extension
rst!Photo
rst!Notes
rst!ReportsTo

Just figured it out, I used:
frm.RecordSet.Fields(tagName)

Thanks for help ADezii, Me.RecordsetClone was a good hint.

It is usually a good idea to always avoid accessing the actual Form's Recordset in any manner, which is why I always use RecordsetClone whenever appropriate.
