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.
