I'm using MS Access 2000 Sp1. I don't know if this is a but specific to this older version, but this problems does exist with this version.
I create a form using text boxes, combo boxes etc, which have code in various event procedures (ongotfocus, afterupdate, onchange, etc)
Later, decide to use the tab control, so I create a tab.
I copy the controls originally created (before the tab was inserted), and paste the controls onto one tab.
At this point, everything appears to paste correctly, although none of the events work.
To fix an after update event, I need to go to the process that I would to create an event, and then PRESTO... the original event is now accessible.. so I simple close and the problem seems solved.
In my case however, I've pasted about 30 controls, and I can't remember which controls use events, and which events they use.
Since the events are still in the code, it seems like there should be an easy what to have the new tab control, link up with them.
