How could I use vba to close an "on the fly" created Listbox if
ignored by the user.... if I use the Worksheet_SelectionChange event
and say.. ActiveSheet.ListBoxes("OfficeList").Delete for example it
is fine if the listbox is open but gives and error if not. I have
tried to poll for any open Listboxes ( and hences close them ) but
can't get the code right or am I on the "wrong road" ...?
Cheers

ActiveSheet.ListBoxes("OfficeList") generates error if OfficeList does
not exist. so use that fact

function GetOfficeListBox as listbox
on error goto trapit
set GetOfficeListbox = ActiveSheet("officelist")
exit function
trapit:
set GetOfficeListbox = nothing
end function


in your main program


dim olb as listbox
set olb = getOfficeListbox ()
if not olb is nothing then
olb.delete
end if

--------

eventually getOfficeListbox can have a name of listbox as paramater and
be used to get listbox reference or nothing for any listbox.
