I want the user to select a list of items.  The form would contains two list
boxes -- one list box contains a list of all items, the other list box
contains a list of selected items from the first list box.  The function
would look something like:

boolResponse = AddRemoveItems(colAll, colSelected)

where
   colAll is a two-dimensional collection of items (id and description)
   colSelected is a one-dimension collection of ids of the selected items
which is returned
   boolResponse is boolean; if user cancels form then false; otherwise, true
and colSelected contains selected items

I want this function to be as generic as possible so that it can be used in
different applications.

Can you get me started?

Thanks in advance.

Fortunately, Microsoft already had the same idea.

Check the help files for "MultiSelect Property".
