This sample demonstrates how to write a VBX control using MFC 2.0.
This sample uses _USRDLL. This enables this sample to be used used
by MFC and VB applications.  Using _AFXDLL will restrict this sample
to be used only by MFC applications.

It is important that the MODEL, Property and Event structures be
declared NEAR in order for this control to work correctly.  It is
also important that you create an object of a class derived from
CWinApp.  This allows some MFC initializations to take place.  

Depressing the left button inside the control when your application
is executing will display a message box indicating the point of your
mouse click.   

You can use AppStudio to set the properties of this control.
You can use ClassWizard to manipulate CVBCtlWnd class if needed.

For more information on _USRDLL and _AFXDLL refer to technote 33.

P.S. The include files VBAPI.H and VBAPI.LIB are not included with this 
     sample.  In order to re-compile this sample, you will need this file.
     This file comes with the Visual Control Pack or VB PRO.
     If you are writing vbx controls, then you will need either
     of these packages.
