                      Release Notes ooDialog 4.2.3
                      ============================

The ooDialog 4.2.3 release is a routine update, providing some
incremental improvements and a few bug fixes.

ooDialog 4.2.3 can be installed to any ooRexx installation, 4.1.0 or
later.

Beginning with the release of ooDialog 4.2.0, the installation of
ooDialog has been decoupled from the interpreter.  ooDialog 4.2.3
installs over the top of any ooRexx installation.  It replaces the
version of ooDialog in the ooRexx installation with ooDialog 4.2.3.

This type of ooDialog installation is called an "independent" ooDialog
installation to indicate the ooDialog installation is independent of an
ooRexx installation and, to a degree, the version of ooRexx installed.

ooDialog 4.2.3 is distributed with ooRexx 4.2.0.


Indpendent Installation
========================================================================

The independent installation package is simple, done through a typical
Windows installer.  Pick the installation package that matches the
bitness of the ooRexx installation.  I.e., a 32-bit package for a 32-bit
ooRexx and a 64-bit package for a 64-bit ooRexx.

The installer will detect the installed ooRexx, location and version.
If the ooRexx version is less than 4.1.0, or if there is no installed
ooRexx, the installer will abort with a message explaining the problem.
Otherwise the installer will replace the current ooDialog with ooDialog
4.2.3.

Note that the actions of the installer are dependent on the version of
ooRexx, not the version of the installed ooDialog.  For instance, if the
installed ooDialog is version 4.3.0, but for some reason the user is not
happy with that version, running the ooDialog 4.2.3 installer will
replace the 4.3.0 version with the 4.2.3 version.

At the time of the installation, *all* ooDialog programs must be halted
and the ooDialog PDFs must be closed if they happen to be opened.

New Functionality in ooDialog:
------------------------------

The stand alone ooDialog installer now allows the user to choose to skip
the installation of the documentation and / or the example programs.
This matches the ooRexx installation where the documentation and sample
programs do not have to be installed.

An ooDialog executable, ooDialog.exe, has been added to the
distribution.  The executable will run ooDialog programs in a manner
similare to rexxhide, provides command line information on the version
of ooDialog installed, and can be used to set up file types and
associations for ooDialog programs.


New dialog classes:
-------------------

CommonItemDialog class

OpenFileDialog class

SaveFileDialog class



New utility classes:
--------------------

CommonDialogCustomizations class

ComConstants class

ShellItemFilter class

CommonDialogEvents class



New Methods:
------------

In the Application class:

requiredOS()       Checks that the current operating system is at least
                   the minmum specified.

updateWindow()     Causes an immediate repaint of an invalid region in
                   the window.  Does nothing if there is no invalid

                    for the specified item.

setStateImage()     Assigns the state image index in the image list for
                    the specified item.


Enhanced Methods:

In the TreeView class:

getImageList()      Enhanced to take a keyword for the type of image
                    list in addition to the raw number.

setImageList()      Enhanced to take a keyword for the type of image

            file that is executing and sets the .application srcDir
            attribute to that value.


New samples:
------------

* oodialog\controls\ComboBox\comboBoxTypes.rex

Demonstrates what the 3 types of combo boxes look like.  Shows how to
use the removeFullColor() and setFullColor() methods of the ComboBox
class.

* oodialog\controls\ListBox\incrementalSearch.rex

Shows how to implement an incremental search feature for the items in a
list box and over-ride the list box control's internal incremental
search.

* oodialog\examples\genGUID.rex

An example showing how to use the .DlgUtil's genGUID() method.  Also
provides a simple application that can be used to generate GUIDs for any
use.

* oodialog\examples\openSaveFileDemo.rex

An example showing a number of different uses of both the Open File
Dialog and the Save File Dialog.  Demonstrates the most common usage
patterns.

* oodialog\examples\saveFileWithFilter.rex

ResizingAdmin and BrowseForFolder classes.


Enhanced Samples:
-----------------

All of the samples have been enhanced so the they can locate any needed
resource files no matter which directory they are executed from.  This
allows them to run correctly if, for example, they are dragged and
dropped on ooDialog.exe.



Known Problems, "Gotchas," and Solutions with Independent Installations
========================================================================

* Problem:

The ooRexx installer creates a log of the files it installs.  When the
uninstaller runs, the user can select to only uninstall files logged
during installtion.  An indpendent ooDialog installation may install
some example programs, documentation files, and shortcuts not recorded
in the log file.  When ooRexx is uninstalled or upgraded, these files
and shortcuts may not be deleted.

  Solution 1:

  Before uninstalling ooRexx, install the independent ooDialog that
  matches the ooRexx installation.  I.e., if the ooRexx installation is
  any 4.0.x, or 4.1.x ooRexx version, install the ooDialog 4.1.0
  indpendent installation. Then when ooRexx is uninstalled, all ooDialog
  files and shortcuts will be removed because the files and shortcuts
  exactly match what was installed during the ooRexx installation.

  Solution 2:

  After uninstalling ooRexx, manually delete any files in the old ooRexx
  installation directory.

* Gotcha:

  The independent ooDialog installation deletes the entire ooDialog
  samples subdirectory tree.  This will delete any personal files
  that may have been put there after ooRexx was installed.

  Solution 1:

  Do not put personal files in the %REXX_HOME%\samples\ooDialog
  subdirectory tree.

  Solution 2:

  Before executing the independent ooDialog installer, move or back up
  any personal files that may be in %REXX_HOME%\samples\ooDialog
  subdirectory tree.
