ALL RIGHTS RESERVED Patrick Lassalle 2, rue Gutenberg 92100 Boulogne France Tel.: 33 1 46 03 42 20 Compuserve ID: 100325,725 August 1, 1994 =========================================================== -------- Contents -------- Part Description ---- ----------- 1 What is EasyNet Custom Control? 2 Version 1.31 enhancements 3 Technical info 4 Notes on running the demo program 5 How to register? -------------------------------------------- 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. Many properties and events allow you to "customize" your diagramming application. -------------------------------------------- Part 2 - Version 1.31 enhancements -------------------------------------------- - METAFILE: In previous versions, copying an EasyNet diagram to a Windows MetaFile did not work very well especially when the metafile was pasted into a Winword document. Now this bug is fixed. You can copy a selected portion of an EasyNet diagram with the following instruction: Net1.EditAction = 5 and you can copy the whole diagram with the following instruction: Net1.EditAction = 7 - VERSION MANAGEMENT: this feature is now included in order to avoid cases when a Visual Basic application created with a new version of EasyNet runs on a system with an older version. - The Welcome sample has a new look! - plus minor changes. ----------------------------------------- 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 into clipboard using METAFILE format (see EditAction property). * 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. 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 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. * 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. ------------------------------------------ Part 5 - How to register? ------------------------------------------ The demonstration version of the EasyNet control is fully functional but may only be used in the development environment.
