Ok here is my question:
I have an access application that I use to enter sensitive information. If somebody makes a change to one record I want to be able to track the field that was changed the user name of the person who logged on to my database and the change made. I want to create a table that gets this information thru vb code or queries. Please send me sample code assuming a simple record with name, age, DOB fields and the mechanism to track changes to this record. Remember I need to know who did it, when, what fields were changed and what were the old and new values for those fields. thanks

I did this by adding a memo field to the data record. When you populate the fields place the *same* data into the .Tag of the control as you put in the .Text. Then at save time you watch to see if .Text=.Tag, if they don't, then you know that particular field has been updated. I then just add the info to the start of the memo field with something like:

DIM obj as Object
'
for each obj in Form.Controls
if typename(obj) = "TextBox" then
  if obj.text <> obj.tag then
    RS!memo = "Data Field" & obj.name & "changed from: " & obj.tag & " to: " & obj.text & " by: " & user & " on: " & format(now, "hh:mm dd-mmm-yy") & rs!memo
  endif
  '
endif
'
next obj

This is off the top of my head, but I have written this (the code is at home) and it DOES work.

I believe you understood what i am ying to do very well but i did not quite get the idea. Please clarify when you say:
1)"adding a memo field to the data record"
you mean adding a field to let's say the customer table that i am trying to track.
2)"populate the fields" means adding a new member right?
3)*same* what does this mean?
4)".Tag of the control as you put in the .Text" what control?, are you talking about the same text box where i am entering data?
5)Do you place the code that you gave me on the general section of the code window?
Thanks!!!!

1) Yes
2) When you fill your screen with data from the record you do:

Text1.Text = Trim("" & RS!Fieldname)
Text1.Tag = Text1.Text

3) Same means *same*
4) Yes
5) No, code goes in click event of [Update] button
