This package includes a VB-authored subclassing control. A
subclassing control allows Visual Basic programs to detect messages
for which Visual Basic does not provide direct support for. This
controls is documented below.

The Subclass OCX is freeware that you can use freely with your own
programs. However, you may only distribute Subclass.ocx as a) part of
your own application that uses this control or b) within this complete
and unmodified package (i.e., you may distribute the entire
SysTray.zip file).

Using Subclass.ocx
------------------

Note that you must register Subclass.ocx with the system registry in
order to use it. To do this, select the Project/Components command
within Visual Basic. Then check SoftCircuits Subclass Control from the
list. NOTE: This control was not designed for, nor tested with, Visual
Basic 4.

Properties
----------
hWnd        Handle of the window to be subclassed. Must be set at run time.

Messages        Specifies which messages you want to detect. Must be set at run
                time. The Messages property operates like an array and allows you
                to specify multiple messages like this:

                Subclass1.Messages(WM_MENUSELECT) = True 'Detect this message
                Subclass1.Messages(WM_SIZE) = True       'Detect this message
                Subclass1.Messages(WM_PAINT) = False     'Don't detect msg (default)

Methods
-------
CallWndProc     Invokes the original window procedure. Invoke only from within
                the WndProc event.

Events
------
WndProc  This event is invoked when any of the specified messages are sent
                to the specified window. The arguments are specific to the message
                sent (see the Windows API documentation for details). The Result
                argument is the value returned to Windows. This argument is 0 by
                default.
