Q57884: Listbox Initialized Incorrectly in BASIC 7.00 UI Toolbox

Article: Q57884
Product(s): See article
Version(s): 7.00 7.10
Operating System(s): MS-DOS

The ListBox FUNCTION in the User Interface (UI) Toolbox WINDOW.BAS
file provided with Microsoft BASIC Professional Development System
(PDS) versions 7.00 and 7.10 does not behave correctly when a list box
is first activated. On initialization, the keyboard cursor is set on
the OK button instead of in the list box.

Microsoft has confirmed this to be a problem in Microsoft BASIC PDS
versions 7.00 and 7.10 for MS-DOS. We are researching this problem and
will post new information here as it becomes available.

Without the modification listed below, you must press the TAB key
twice before using the cursor keys to move into the list box.

To correct this behavior, the initial value of currButton (set early
in the ListBox FUNCTION) must be changed from 2 to 0. The following
are the statements from the ListBox FUNCTION of WINDOW.BAS adjacent to
(and including) the incorrect statement:

   currTop = 1
   currPos = 1
   currButton = 2       '****** Need to change this to currButton = 0

   GOSUB ListBoxDrawText

This correction should be made and the libraries rebuilt to have the
cursor positioned properly in the list box.
