>I'm having trouble with my custom write buffer.When I am on a record and make changes then go to the next record using my toolbar the writebuffer traps for changes and allows me to commit or revert my changes. But if I were to make changes then select my listbox and go to another record, the changes are already committed. How do I check if data has changed in any of my text boxes and prompt the user to save, discard or cancel the last action?

Jon,

This happens because you are still on the same record when you clicking your toolbar, and your WriteBuffer fires OK,
But when you move record pointer through the listbox and use row buffering, the changes are written automatically, right, and you can do nothing about that.
The solution may be to use table buffering, if it suits. When you move
the record pointer through listbox you may trap this, for example,in Listbox InteractiveChange event, and use GETFIELDSTATE() to check, if particular field was updated then ask for confirmation, and then force TABLEUPDATE() to update current record. It may be complicated, if you have many fields to update.
In case of row buffering, may be you can put the trap to Listbox GotFocus(), that just off the top of my head, I didn't try it :)
Well, just some thoughts.
