Access Error Method Example

Access Error Method - You can use the Access Error method to return the description associated with a Microsoft Access or DAO error when the error hasn't actually occurred.
However, you can't use the Access Error method for ADO errors in Visual Basic.

Application Object AccessError method Visual Basic example:

Function ErrorString(ByVal lngError As Long) As String

            ' begin Access Error method code

Const conAppError = "Application-defined or " & _
"object-defined error"

On Error Resume Next
Err.Raise lngError

If Err.Description = conAppError Then
    ErrorString = AccessError(lngError)
ElseIf Err.Description = vbNullString Then
    MsgBox "No error string associated with this error."
Else
    ErrorString = Err.Description
End If

' end Access Error method code

End Function
