procedure BeginUpdate;
Description
The BeginUpdate and EndUpdate methods speed repetitive tasks by eliminating triggering of the OnNavigate event.
Batches of, say, Add calls can be sandwiched between BeginUpdate and EndUpdate. Since the OnNavigate event is typically used to refresh a screen display, its elimination can speed things up considerably.
BeginUpdate and EndUpdate can be nested -- i.e., it takes two EndUpdates to balance two BeginUpdates.
