I've had a request to return the value entered in a field by user to the previous value if it does not pass data validation criteria.
Where I can trap this in the BeforeUpdate event I am using a global variable to store the .oldvalue and then reassigning in the AfterUpdate event.
However data validation triggered by table structure exceptions (such as text in a number field) trigger the Form_Error event before the BeforeUpdate event and the Form_Error event does not relate to a specific field that I can store as an old value.
I could get around this by setting up the table as completely free text in all fields with nulls allowed, such that there would be no Form_Error event triggered and all validation handled in BeforeUpdate
Is this really the way I need to go about this? It seems odd to have to set up a nonsense table structure to handle errors but I'm struggling to come up with another method
I'm turning this comment into an answer. This is the gist of how to revert from the Form_Error.
Private Sub Form_Error(DataErr As Integer, Response As Integer)
Undo
Response = 0
End Sub
You could do more like display a message on the screen saying what you did to you user then hide it on a timer event. Just something so their not sure why their data went away.
