Hello you all. This is Edson from rainy days in Brazil (finally).
I need to learn how to generate either a form or report able to show me the history of data changes made by users in the fields of Access Objects. I'm more interested in Forms, since the users will use Forms to change data in the db.
Let me give an example:
My db has, for instance, a form named Frm1 and a form named Frm2. Both were built including several fields such as text boxes, combo boxes, etc.
So, if the user Paul first changes the field Color of the record Id 235 in the Frm1 from Green to Yellow, and then, down the road George changes the field Size of the record Id 14 in the Frm2 from Big to Small, I need to know what changes were made, by who, and when changes happened. Also, it is important to know if a record Id is added or excluded.
My final intent is to have a report/form that shows some sort of user activity log which I think could be like this:
Date--------Time----------User-----Form------RecId------Action------Field-----From-----------To
Dec12,14---15:12:35-----Paul-----Frm1--------235------Changed---Color----Green-----------Yellow
Dec18,14---07:05:19-----George--Frm2---------14------Changed---Size-----Big--------------Small
Dec22,14---09:23:59-----Sean----Frm2--------116------Deleted
Dec23,14---11:07:03-----Paul-----Frm2--------321------Added
etc...
By sorting this output by date, form and field it will easy to check/audit for user processing mistakes.
I believe it is possible but I have no idea how to make it. I know enough to build tables, queries, forms and reports, but don't know how to structure such thing. Could you supply me with some guidelines, or examples, or macros, please? Specially on the VBA to capture such information. What kind of form event should I setup?
It would be very handy. Thank you.
