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

 EasyNet is a "vbx" (Visual basic Custom Control) which allows 
to develop QUICKLY an application that needs to manage a network 
diagram:
	* workflow
	* data base diagram
	* organigrams
	* communication networks
	* state transition diagrams
	* etc...

INTERACTIVITY
-------------

An EasyNet diagram contains nodes and those nodes can be linked.
Drawings can be made interactively or programmaticaly:
 
	* Network items (nodes or links) may have attributes which  
	can be easily modified (shape, colors, pen width or style, etc)
	* Pictures (icon, bitmap or metafile) may be displayed inside nodes.
	* You can move, resize, stretch each item.
	* Multiselection allowed
	* Transparent items, sleeping items, hided items etc...
	* Links can be oriented or not.
	* Links can be composed of several segments.
	* 4 link arrowhead shapes

OPEN
----

* You can associate data (text, picture, integer, reference to other 
data like a database record) to each item. 

* METAFILE copy: you can copy an EasyNet diagram onto the 
clipboard and paste it in Window Write, in PaintBrush, Excel, 
Winword, WordPerfect, in a VB picture, etc... 
And the result can be resized.
For instance, you may paste the metafile in a Winword document, 
double-click on the picture, adjust the margins so that
there's room for other drawing objects, use the drawing 
tools to draw some lines, circles, etc, close the picture,
select it, copy it to the clipboard, etc... Try this with
Welcome demo.

* METAFILE saving. You may save an image of your EasyNet diagram
on disk as a metafile.


NAVIGATION
----------

 You can navigate in the EasyNet diagram (for instance, get every
nodes linked to one given node).

CUSTOMIZABLE
------------

 Many properties and events allow you to "customize" your
diagramming application (CanDrawNode, CanSizeNode, 
CanStretchLink, ReadOnly, ScrollBars, etc...).


--------------------------------------------
Part 2 - New version enhancements
--------------------------------------------

* ImageFile property allowing to set a file name to which the 
  metafile is written when EditAction is set to 8. (FOR THIS 
  FEATURE TO WORK, YOU MUST HAVE A REGISTERED VERSION.)
* Version property that returns current EasyNet version number.
* Hiding property allowing to make items invisible.
* New navigation options (See LoopAction property).
* VB source code to save and load an EasyNet diagram 
  (see Help file: topic Saving/Loading)
  

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

Interface
---------

 EasyNet programmatic interface contains:

  * 83 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 every host environment that is "VB 1 level"
compatible (Visual C++, Borland C++ 4.0, SQL Windows, 
DBase for Windows, etc...).


Misc
----

* EasyNet is a container for other controls.

* Limits for one EasyNet control:
  - 1000 nodes.
  - 1000 links.
  - 15 segments for each link.
  - the total amount of memory available for all the displayed 
    text in one EasyNet control is 64 K.
  - the total amount of memory available for all the tag 
    text (see ItemTag property) in one EasyNet control is 64 K.

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

 This ZIP file contains the following files:

WELCOME.EXE  A demo without source files.

PROJECT1.MAK  (First Demo source files)
FORM1.FRM
ABOUT1.FRM
MODULE1.BAS 

PROJECT2.MAK  (Second Demo source files)
FORM2.FRM
ABOUT2.FRM

PROJECT3.MAK  (Third Demo source files)
FORM3.FRM
ABOUT3.FRM
MDI3.FRM

PROJECT4.MAK  (Fourth Demo source files)
FORM4.FRM
ABOUT4.FRM

PROJECT5.MAK  (Fifth Demo source files)
FORM5.FRM
ABOUT5.FRM

EASYNET.VBX   EasyNet Custom Control 
EASYNET.HLP   EasyNet help file.
README.TXT    This text file.


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.
    Note that the saving procedure used in this program is just an 
    example. You should adapt it to your needs or rewrite a better
    procedure.

  * 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: you bring the mouse cursor into the handle at the
    center of the selected node, press the left button, move the 
    mouse towards the other node. When you release the left button,
    a node is created at this place and a link between the origin node
    and this one is created also. 
    This demo needs xScroll and yScroll properties.

  * Fifth demo illustrates node text Alignment property.
