--------------------------------------------
Part 1 - What is EasyNet Custom Control?
--------------------------------------------

 If you want to develop a Windows application needing diagramming
features, you may develop it quickly with Visual Basic and the
EasyNet control.

 EasyNet control allows to draw net graphs interactively 
in your forms, which means drawing nodes and linking them. 
 So an EasyNet control contains items that can be nodes or links. 
You can resize, move, stretch each item and alter their attributes
(shape, color, transparency, orientation, etc...) 
 You can associate data (text, picture, integer, reference to other 
data like a database record) to each item and you can navigate in
the EasyNet diagram.

  You will find EasyNet useful in following applications:

  * workflow
  * data base diagram
  * organigrams
  * communication networks
  * state transition diagrams
  * ... and all application that needs to manage a network graph.


--------------------------------------------
Part 2 - Version 1.3 enhancements
--------------------------------------------

- 2 new node shapes: ROUND RECTANGLE and DIAMOND

- INCREASED NUMBER OF ITEMS 
  Now you can create 1000 nodes and 1000 links for each control!!!

- display bug corrected: with previous versions and under certain 
  conditions, the text associated to a link was not properly displayed 
  and a window refresh was necessary. This bug is fixed now.

- 4 obsolete events (StartMove, StartLink, etc) have been removed. 
  PointedArea property should rather be used (see demonet1 sample).
  Consequence: applications compiled with older versions of EasyNet  
  will have to be recompiled in order to work with this new version.


-----------------------------------------
Part 3 - Technical info
-----------------------------------------

Interface
---------

 EasyNet programmatic interface contains:

  * 68 properties (26 standards)
  * 17 events (12 standards)
  * 0 method 

 All those properties and events are described in 
EASYNET.HLP file. 


Compatibility
-------------

 EasyNet can work in every versions of Visual Basic. Therefore, 
it can also be used with Visual C++ and Borland C++ 4.0.


Misc
----

* You can copy an EasyNet diagram to clipboard using METAFILE
  format (see demonet1 sample).

* Keyboard management is under the responsability of the
  application using EasyNet. The KeyDown, KeyPress and KeyUp
  events have to be used for this purpose (see demonet1 sample).

* Easynet is a container for other controls.

* Printing, saving and loading an EasyNet diagram is under the
  responsability of the application using EasyNet (see demonet1 
  sample).

Part 4 - Notes on running demo programs
------------------------------------------

 This ZIP file contains the following files:

WELCOME.EXE  A demo without source files. It displays 4 EasyNet 
             controls with different property values and behaviour:

               * The mouse pointer is changing in the "blue" Control. 
               * A keyboard interface is offered in the "yellow" control, 
                 allowing to scroll with up, down, left, right keys.
               * The "green" control does not allow multiselection.
               * The "blue" control contains one "sleeping" node 
                 (it is the yellow one).
               * One control contains the 3 buttons (Help, Exit, About).
                 It has no border. You can only stretch the existing 
                 links between the buttons.

Remarks:
--------

  * EASYNET.VBX and EASYNET.HLP should be copied in your 
    WINDOWS\SYSTEM directory.

  * If you don't know EasyNet, you should run first WELCOME.EXE.

  * First demo allows to draw diagrams, save them in files and print
    them. It shows also how to add a keyboard interface and how to 
    change cursor shape using "PointedArea" property.

  * Second demo focuses on EasyNet capabilities.

  * Third shows how to use EasyNet in the case of a network 
    application. It is a MDI sample application. The following 
    properties are illustrated: Picture, Transparent, DrawStyle.

  * Fourth demo shows how to combine node and link adds into a 
    single step. It needs xScroll and yScroll properties.

Part 5 - How to register?
------------------------------------------ 

 The demonstration version of the EasyNet control is fully 
functional but may only be used in the development environment.
If you generate an EXE file with this version of the EasyNet 
control but without an EasyNet license file, then any attempt 
to use this EXE file will display a dialog box explaining that 
it has been generated without license file and the control 
will fail to load.

 If you like EasyNet control then you can receive a full version 
by registering as follows:

  1) Either in the SWREG forum on Compuserve. The fee is $99 and 
  the Registration ID number is 2547.Then you will receive EasyNet
  by Compuserve E-Mail and the registration fee will be billed to 
  your Compuserve Account.

  2) Either by completing and sending the Order Form, along with a
