Hi,
I have an audit trail text field called "Updates" setup in my forms to
track the changes to the controls when the fields are updated. The only issue
is the audit trail is listing fields that have not been changed. Any idea
what i can change so it only lists the fields that have been updated? Here is
the code to the module that i have setup that controls the auditfield.
Option Explicit
Function AuditTrail()
On Error GoTo Err_Handler
Dim MyForm As Form, C As Control, xName As String
Set MyForm = Screen.ActiveForm
'Set date and current user if form has been updated.
MyForm!Updates = MyForm!Updates & Chr(13) & Chr(10) & _
"Changes made on " & Date & " by " & CurrentUser() & ";"
'If new record, record it in audit trail and exit sub.
If MyForm.NewRecord = True Then
MyForm!Updates = MyForm!Updates & Chr(13) & Chr(10) & _
"New Record """
End If
'Check each data entry control for change and record
'old value of Control.
For Each C In MyForm.Controls
'Only check data entry type controls.
Select Case C.ControlType
Case acTextBox, acComboBox, acListBox, acOptionGroup
' Skip Updates field.
If C.Name <> "Updates" Then
' If control was previously Null, record "previous
' value was blank."
If IsNull(C.OldValue) Or C.OldValue = "" Then
MyForm!Updates = MyForm!Updates & Chr(13) & _
Chr(10) & C.Name & "--previous value was blank"
' If control had previous value, record previous value.
ElseIf IIf(IsNull(C.Value), "", C.Value) <> C.OldValue Then
MyForm!Updates = MyForm!Updates & Chr(13) & Chr(10) & _
C.Name & "==previous value was " & C.OldValue
End If
End If
End Select
Next C
TryNextC:
Exit Function
Err_Handler:
If Err.Number <> 64535 Then
MsgBox "Error #: " & Err.Number & vbCrLf & "Description: " &
Err.Description
End If
Resume TryNextC
End Function
