what property or method should I use in combo box to

[Amanda]

User is going to be transferring items out of combobox to listbox and
vice versa keeping ascending and desending order respectively at all
time.

If user selects the last item in combobox, the program is supposed to
display a message box stating that there is no more item in the
combobox with OK button to be clicked as the only option and upon
clicking OK, the program should terminate, i.e the program should check
to ensure that the ComboBox contains at least one item.

What property or method should I use to check that the user has
selected the last item left in combo box? Or should I just keep track
of the count of items and when the last one is selected, display the
message and terminate the program?

Never mind. Got that part.

Now, how do I set descending order for list box?

There are 2 cases
1) Use Array.Sort + Array.Reverse
2) Override ListBox.Sort in custom class inherited from ListBox

We can't use array in this assignment yet. No inheritance either.

Data is placed at design time in combo box. At runt ime, move back and
forth (as long as at leats one entry is left in combo box) to the list
box but the data must be in descending order in list box at all time.

I set sort property to true in design time for both combo and list box
which by default, it seems is ascending order.

Hello Amanda,

There is no other way for desc sort except I described -data sort or override
Sort of ListBox control
