- I am using ABF to maintain a tabel of items. The user should be able to add
- and delete these items, and modify most of the information associated with
- the item.
-
- Each items has a key value. I want to prevent the user from modifying this
- key value. Defining the column DISPLAYONLY is no good, for the user has to be
- able to specify the value when adding new items. By the time I catch the error
- I cannot change it back, as the original value is lost.
-
- Is there any way I can:
-
- a. Allow creation and deletion of a column in a table field, without also
- allowing modification?
- b. Have access to the old value, so I can change it back?
-
- Or is there any other way of doing what I want?
-
- Thanks in advance.
