/**
 * The dialog procedure function for all regular ooDialog dialogs.  Handles and
 * processes all window messages for the dialog.
 *
 * @param hDlg
 * @param uMsg
 * @param wParam
 * @param lParam
 *
 * @return LRESULT CALLBACK
 *
 * @remarks  The WM_INITDIALOG message.
 *
 *           In CreateDialogParam() / CreateDialogIndirectParam() we pass the
 *           pointer to the PlainBaseDialog CSelf as the param.  The OS then
 *           sends us this value as the LPARAM argument in the WM_INITDIALOG
 *           message. The pointer is stored in the user data field of the window
 *           words for this dialog.  We do the same thing for the child dialogs,
 *           see the WM_USER_CREATECHILD message.
 *
 *           Note that when the child dialogs of the category dialog get
 *           created, we recieve a WM_INITDIALOG for each of them.  These child
 *           dialogs are all running on the same thread as the parent category
 *           dialog.  We don't want to do a bunch of nested AttachThreads()
 *           because we only do 1 DetachThread() for each window message loop.
 *           So, we check to see if dlgProcContext is null before doing the
 *           AttachThread().  Note that as of ooDialog 4.2.0, the CategoryDialog
 *           class is deprecated.
 *
 *           The WM_USER_CREATECHILD message.
 *
 *           This user message's purpose is to create a child dialog of this
 *           dialog and return its window handle. Child dialogs are only created
 *           to implement the CategoryDialog and at this time are always created
 *           dynamically (from an in-memory template.) The dialog template
 *           pointer is passed here as the LPARAM arg from
 *           DynamicDialog::startChildDialog().
 *
 *           These child dialogs do not have a backing Rexx dialog. There is no
 *           unique CPlainBaseDialog struct for them.  Instead, at this time,
 *           all interaction with the child dialogs is done through the
 *           CPlainBaseDialog struct of the parent.  For each child dialog, we
 *           set the CPlainBaseDialog struct of the parent in the window words
 *           of the child dialog.  Prior to the conversion of ooDialog to the
 *           C++ API, when a message came in for a child dialog, a search was
 *           made through the DialogTable to try and find the parent dialog.
 *           This has been disposed of and the CPlainBaseDialog struct is just
 *           pulled out of the window words.  Note that as of ooDialog 4.2.0,
 *           the CategoryDialog class is deprecated.
 *
 *           The WM_USER_CREATECONTROL_DLG
 *               WM_USER_CREATECONTROL_RESDLG messages.
 *
 *           These user messages create true child dialogs with a backing Rexx
 *           dialog and individual CSelfs (CPlainBaseDialog structs).
 *
 *           The WM_USER_CREATEPROPSHEET_DLG message.
 *
 *           This user messages creates a modeless Windows PropertySheet dialog.
 *           This dialog does have a backing Rexx dialog along with an
 *           individual CSelf.
 *
 *   @remarks  The existing, old, architecture of ooDialog uses delDialog() to
 *             both terminate the dialog and clean up the CSelf struct. No
 *             WM_COSE is sent to the window procdure.  Rather, in delDialog() a
 *             DestroyWindow() and PostQuitMessage() is done.  But, the
 *             PostQuitMessage() is done before DestroyWindow() AND
 *             DestroyWindow() can not be used on a window in a different
 *             thread.  Because of this, 1.) This procedure never gets a
 *             WM_DESTROY message.  2.) The DestroyWindow() probably usually
 *             fails.  This is likely the cause of memory leaks.
 *
 *             This whole architecture need to be re-thought out.  Rather than
 *             use delDialog() to terminate the dialog, it seems to me it would
 *             be better to send a WM_CLOSE message, do a DestroyWindow() in the
 *             WM_CLOSE processing, and use the WM_DESTROY processing to clean
 *             up.  I.e., use the normal Windows strategy.
 *
 *             It is tempting to set pcpbd->hDlg here.  But, if we do we break
 *             the deprecated CategoryDialog.  So, for now we don't do that.  At
 *             some point, it would be best to simply say the CategoryDialog
 *             support is removed and do that.  Note that the chidl dialogs of
 *             the CategoryDialog, *only* use this window procedure.  So, it is
 *             only here that we need to worry about this.  It is the
 *             customDrawCheckIDs() that needs the handle.  No category child
 *             dialog can have custom draw, so we set pcpbd->hDlg if we are
 *             going to call that function.

/**
 * This function will (should) cleanly end the dialog and the Rexx dialog object
 * when things needed to be terminated for unusual reason.  It can put up a
 * message box to inform the user of the circumstances depending on the args.
 *
 * @param pcpbd  Pointer to CSelf struct for the dialog (the PlainBaseDialog
 *               CSelf.)
 * @param hDlg   Window handle of the dialog.
 * @param t      Error type.
 *
 * @return False always.
 *
 * @remarks  For all the original types of ooDialog dialogs (4.0.1 and
 *           previous,) DestroyWindow() causes a WM_DESTROY message to reach
 *           RexxDlgProc(). The dialog procedure then posts a quit message, we
 *           fall out of the message loop and things unwind cleanly.
 *
 *           Setting abnormalHalt to true ensures we don't invoke leaving() and
 *           that the dialog return gets set to 2.  Calling ensureFinished()
 *           terminates the thread waiting on the finished instance variable.
 *
 *           This works fine for modeless property sheets, but modal property
 *           sheets hang.  The abortPropertySheet() essentially does a
 *           programmatic close and prevents any of the property sheet pages
 *           from nixing the close.
 *
 *           Note that if we do not call ensureFinished here, we get a crash in
 *           the Window message processing loop.

/* genericCommandInvoke
 *
 * The simplest form of invoking the Rexx method connected to a WM_COMMAND
 * message.  And actually, all WM_COMMAND messages are invoked through this
 * function. As far as I can tell, the return to the operating system is never
 * meaningful.
 *
 * The Rexx method is invoked with two arguments, the WPARAM and LPARAM
 * paramters of the WM_COMMAND message.  There is never any more meaningful
 * information we could send to the event handler (*1).  Since the return is
 * ignored by the OS, the return from the Rexx event handler is never
 * meaningful.
 *
 * Note that for WM_COMMAND messages, lParam is always the window handle of the
 * dialog control, if a control initiated the message.  For menu items and
 * accelerators, it is always 0. So, converting lParam to a pseudo pointer is
 * always the correct thing to do.
 *
 * (1)  We could create the Rexx control object from the hwnd.  But if we decide
 * to do that, we will just add it as the third argument.
 *
 * @remarks  The original ooDialog always sent the numeric value of wParam as
 *           the first arg and the numeric value of lParam as the second arg to
 *           the event handler.  Sending the control ID, the notification code
 *           and the Rexx dialog object constructed from the window handle makes
 *           much more sense.  But those args must be added as the next 3 args
 *           for backwards compatibility.  If thenotification comes from a menu
 *           or accelerator, the Rexx dialog control object should come out as
 *           the .nil object.

 *           exceeds 80 TCHARS in length.  If we alloc the memory, when do we

 *           entry.  We are assuming that only 1 tool tip text can display at
 *           any one time.  When we get TTN_NEEDTEXT, we copy the text returned
 *           from the user into this static buffer.  Then we do not need to

 *
 * @return The result of the search.  Either no entry was found, an entry was
 *         found reply true in the dialog procedure, or an entry was found reply
 *         false in the dialog procedure.
 *
 * @remarks We search through the message table looking for an entry where,
 *          after applying the filters to the WPARAM and LPARAM arguments, we
 *          have a match.  When we find a match, we check for a "tag" in the
 *          table entry.  If there is a tag, we can narrow the processing down.
 *          This concept of a "tag" is an addition to the original ooDialog
 *          code.
 *
 *          When we have matched a message in the table, but don't match a tag,
 *          the original ooDialog code would have invoked the the Rexx method
 *          with two arguments wParam and lParam turned into numbers. This is
 *          not very useful. The first arg would be idFrom and the second a
 *          meaningless number, a pointer to the NMHDR struct.
 *
 *          However, with the newer C++ native API, and since we know this is a
 *          WM_NOTIFY message, we can invoke the method with 4 arguments: the
 *          control id that sent the notification, the hwnd of the control that
 *          sent the notification, the notification code itself, and the Rexx
 *          control object that represents the control that sent the
 *          notification.
 *
 *          This can actually be useful ... but I'm not sure about backwards
 *          compatibility with that change.  But, it seems like an okay change.
 *          The first arg sent will be the same.  The second arg will appear to
 *          be the same, a seemingly meaningless number.  Any existing code
 *          could not have done anything with that number, new code could use it
 *          since it is a valid window handle.  Existing code would not have
 *          used args 3 and 4, they didn't exist.  New code can use them
 *          effectively.
 *
 *          MSDN says, or at least implies, that *all* WM_NOTIFY messages are
 *          from dialog controls.

 * @remarks  The command message table is allocated during the plain base dialog

 *           allocated.  Better to check and raise a condition for this
 *           situation.
 *
 *           Caller must ensure that 'method' is not an empty string and that
 *           winMsg, wParam, lParam are not all 0.
 *
 *           If the message table is full we reallocate a table double in size
 *           through LocalReAlloc().  Without the LMEM_MOVABLE flag, the realloc
 *           can fail.  Note that even though the LMEM_MOVABLE flag is used, if
 *           the memory object being reallocated is fixed, the returned memory
 *           object is still fixed.  LocalLock() does not need to be used.
 *
 *           LMEM_MOVEABLE:  If uBytes is nonzero, enables the system to move
 *           the reallocated block to a new location without changing the
 *           movable or fixed attribute of the memory object. If the object is
 *           fixed, the handle returned may be different from the handle
 *           specified in the hMem parameter.

 * @remarks  Caller must ensure that 'method' is not an empty string and that
 *           winMsg, wParam, lParam are not all 0.
 *
 *           See remarks in addCommandMessages() for some relevant information.
 *
 *           Note that the message filtering code was designed when 32 bit
 *           Windows was all that was available, and for some time ooDialog was
 *           32 bit only.  With the advent of 64-bit ooDialog, the filtering may
 *           be incorrect.  Take for instance the case where filter is on a
 *           window handle.  All the ooDialog code would set the filter to be
 *           0xFFFFFFFF.  But, a 64 bit window handle could be 0x00021cdffffffff
 *           and the filter would fail.
 *
 *           In C / C++ code the proper thing to do is to use UINTPTR_MAX rather
 *           than 0xFFFFFFFF for a filter, in cases where the thing being
 *           filtered could be a 64 bit value.  In most all cases, this has been
 *           fixed, but it is something to watch out for.

 *
 *           The GetKeyState() API adjusts the state of the control, alt, shift
 *           keys as it processes the message queue.  So, the Rexx programmer
 *           can specify that she wants to detect this situation by adding

 *  the WPARAM and LPARAM for the message, a filter for the message and its
 *  parameters, and the method name. Using the proper filters for the Windows
 *  message and its parameters allows the mapping of a very specific Windows
 *  event to the named method.
 *
 *  @param  methodName   [required]  The method name to be connected.
 *  @param  wm           [required]  The Windows event message
 *  @param  _wmFilter    [optional]  Filter applied to the Windows message.  If
 *                       omitted the filter is 0xFFFFFFFF.
 *  @param  wp           [optional]  WPARAM for the message
 *  @param  _wpFilter    [optional]  Filter applied to the WPARAM.  If omitted a
 *                       filter of all hex Fs is applied
 *  @param  lp           [optional]  LPARAM for the message.
 *  @param  _lpFilter    [optional]  Filter applied to LPARAM.  If omitted the
 *                       filter is all hex Fs.
 *  @param  _willReply   [optional]  The conventional _willReply arg, true,
 *                       false, or sync.
 *
 *  @return  0 on success, 1 on failure.
 *
 *  @note     Method name can not be the empty string. The Window message,
 *            WPARAM, and LPARAM arguments can not all be 0.
 *
 *            If incorrect arguments are detected a syntax condition is raised.
 *
 *  @remarks  All internal use of this method has been removed.  Therefore the
 *            old internal use of the _tag argument, which was never documented,
 *            is no longer needed. We change its use in 4.2.4 to allow the user
 *            to specify will reply or sync. This allows the user to specify
 *            invoke dispatch, invoke direct, or invoke sync
 *
 *            Although it would make more sense to return true on succes and
 *            false on failure, the method has been documented as returning 0
 *            for success and 1 for error.
 *
 *            Then only reason we pass methodName to parseWinMessageFilter() is
 *            to have the function check for the emtpy string.  We use
 *            methodName as is if there is no error.

 *                      SELECTFOCUS
 *
 *  @param  methodName  [OPTIONAL] The name of the method to be invoked in the
 *                      Rexx dialog.  If this argument is omitted then the
 *                      method name is constructed by prefixing the event
 *                      keyword with 'on'.  For instance onUserString.
 *
 *  @param  willReply   [OPTIONAL] Specifies if the method invocation should be
 *                      direct or indirect. With a direct invocation, the
 *                      interpreter waits in the Windows message loop for the
 *                      return from the Rexx method. With indirect, the Rexx
 *                      method is invoked through ~startWith(), which of course
 *                      returns immediately.
 *
 *                      For list views, at this time, the default is false, i.e.
 *                      the Rexx programmer needs to specify that she wants to
 *                      reply.  This could change if new key words are added.
 *
 *  @return 0 for no error, -1 for a bad resource ID or incorrect event keyword,
 *          1 if the event could not be connected.  The event can not be
 *          connected if there is a problem with the message table, full or out
 *          of memory error.
 *
 *  @remarks   For the current keywords, if a symbolic ID is  used and it can
 *             not be resolved to a numeric number -1 has to be returned for
 *             backwards compatibility.  Essentially, for this method, all
 *             behaviour needs to be pre-4.2.0.  The only change is that for
 *             tagged list view events, the user can specify to reply directly.
 *
 *             The processing for beginlabeledit and endlabeledit that was done
 *             for the DEFAULTEDIT keyword is not needed for a list-view.
 *             defListEditStarter and defListEditHandler methods are not needed
 *             and the methods are removed from the list-view.  For backwards
 *             compatibility, if the keyword DEFAULTEDIT, we only connect the
 *             defListEditHandler.  We need that to catch the message.  A tag is
 *             added for preserve old behavior and within processLVN() we simply
 *             do what the old defListEditHandler did.  Set the label text if
 *             the user did not cancel, don't set the label if the user did
 *             cancel.
 *
 *             For reference.  The arguments sent to the event handler for
 *             LVN_ENDLABELEDIT were never documented correctly, if at all.
 *             They were as follows.  If the user did *not* cancel the edit:
 *               arg 1 list-view id                   (from wParam)
 *               arg 2 item being edited id (0 based)
 *               arg 3 text user entered.
 *
 *             If the user did cancel the edit:
 *               arg 1 list-view id                   (from wParam)
 *               arg 2 pointer to the NMLVDISPINFO struct as a decimal value
 *                                                    (from lParam)
 *
 *             Note: it is highly unlikely that anyone ever connected
 *             LVN_ENDLABELEDIT in the old ooDialog, but if they did, the
 *             willReply argument would be omitted.  We do a special check for
 *             this and preserve what would have been the old behaviour.  That
 *             is: use invoke dispatch and use the arguments listed above.
 *
 *             The arguments to the event handler for LVN_BEGINLABELEDIT were
 *             never documented at all.  For reference they were:
 *               arg 1 list-view id                   (from wParam)
 *               arg 2 pointer to the NMLVDISPINFO struct as a decimal value
 *                                                    (from lParam)

 *
 *
 *
 *  @param  methodName  [OPTIONAL] The name of the method to be invoked in the
 *                      Rexx dialog.  If this argument is omitted or the empty
 *                      string then the method name is constructed by prefixing
 *                      the event keyword with 'on'.  For instance onPageDown.
 *
 *  @param  willReply   [OPTIONAL] Specifies if the method invocation should be
 *                      direct or indirect. With a direct invocation, the
 *                      interpreter waits in the Windows message loop for the
 *                      return from the Rexx method. With indirect, the Rexx
 *                      method is invoked through ~startWith(), which of course
 *                      returns immediately.
 *
 *                      For scroll bars, at this time, the default is false,
 *                      i.e. the Rexx programmer needs to specify that she wants
 *                      to reply.  This could change if new key words are added.
 *
 *  @return 0 for no error, -1 for a bad resource ID or incorrect event keyword,
 *          1 if the event could not be connected, or other errors.  The event
 *          can not be connected if there is a problem with the message table,
 *          full or out of memory error.
 *
 *  @note  Because this method requires the window handle of the scroll bar
 *         control, it can only be invoked after the underlying dialog has been
 *         created.  This is enforced by raising a syntax condition if needed.
 *
 *         This method does not distiguish between vertical and horizontal
 *         scroll bars because Windows uses the same values for the up and left
 *         flags, and the same values for the down and right flags.  I.e., if
 *         the event is LINEUP and the scroll bar is a vertical scroll bar, it
 *         means the user scrolled 1 unit up, but if the scroll bar is a
 *         horizontal scroll bar it means the user scrolled 1 unit to the left.
 *
 *         Therefore, UP, LINEUP, and LINELEFT all mean the same thing and can
 *         be used with either horizontal or vertical scroll bars.  The same
 *         thing is true for: DOWN, LINEDOWN, and LINERIGHT, for: TOP, LEFT, and
 *         for: BOTTOM, RIGHT.
 *
 *         Raises syntax conditions if incorrect arguments are detected.  Sets
 *         the .SystemErrorCode.
 *
 *         In addition to scroll bar controls, scroll bars can be added to any
 *         window by simply using the WS_VSCROLL or WS_HSCROLL styles to the
 *         window. In this case there is no resource ID for the scroll bar, or
 *         window handle.  We've added support here to connect the event by
 *         using 0 for rxID, but there is still no support in ooDialog for using
 *         the scroll bar methods in this case.  To be added later after 4.2.0
 *         is released.
 *
 *  @remarks   For the current keywords, if a symbolic ID is  used and it can
 *             not be resolved to a numeric number -1 has to be returned for
 *             backwards compatibility.  Essentially, for this method, all
 *             behaviour needs to be pre-4.2.0.  The only change is that the
 *             user can specify to reply directly.

 *             backwards compatibility.  Essentially, except for the keywords

 *             The processing for beginlabeledit and endlabeledit that was done
 *             for the DEFAULTEDIT keyword is not all needed for a tree-view.
 *             This is changed in a similar manner as the list-view was changed.
 *             However, for a tree-view if we do not subclass the edit control,
 *             the enter and the esc key close the dialog.  What we do here is
 *             very similar to what we do in the connect list-view event
 *             function.  See that header doc if more detail is needed.
 *
 *             For reference.  The arguments sent to the event handler for
 *             TVN_ENDLABELEDIT were never documented correctly, if at all.
 *             They were as follows.  If the user did *not* cancel the edit:
 *               arg 1 tree-view id    (from wParam)
 *               arg 2 handle of item being edited
 *               arg 3 text user entered.
 *
 *             If the user did cancel the edit:
 *               arg 1 tree-view id    (from wParam)
 *               arg 2 pointer to the NMLVDISPINFO struct as a decimal value
 *                                     (from lParam)

/** EventNotification::connectUpDownEvent()
 *
 *  Connects a Rexx dialog method with an up down control event.
 *
 *  @param  rxID        The resource ID of the dialog control.  Can be numeric
 *                      or symbolic.
 *
 *  @param  event       Keyword specifying which event to connect.  Only one at
 *                      this time:
 *
 *                      DELTAPOS
 *
 *  @param  methodName  [OPTIONAL] The name of the method to be invoked in the
 *                      Rexx dialog.  If this argument is omitted then the
 *                      method name is constructed by prefixing the event
 *                      keyword with 'on'.  For instance onDeltaPos.
 *
 *  @note   If a symbolic ID is  used and it can not be resolved to a numeric
 *          number an exception is raised.
 *
 *  @remarks  This method is new since the 4.0.0 release, therefore an exception
 *            is raised for a bad resource ID rather than returning -1.
 *
 *            MSDN docs say that the up-down control also sends the
 *            NM_RELEASEDCAPTURE message.  I see no evidence it is ever sent.
 *            And there is this from a news group:
