Enhancing the HP e3000 User Interface

Visual Magic

Empowering your HP e3000 applications for the Web

Visual Magic allows you to:

• Use normal terminal emulation for the HP e3000

• Convert MPE VPlus applications into 2-tier client server architecture

• Web-enable HP e3000 applications using 3-tier architecture

• Transfer data to Excel and integrate applications

Terminal Emulation and Electronic File Transfer

In a conventional MPE interface the application runs on the MPE host and accessed by the user

through a dumb terminal or through an emulation (like Reflection) software on a desktop

computer like PC or UNIX. The interfaces in the terminal can be either character mode or block

mode. These terminal interfaces are available over HP proprietary VT-MGR and telnet protocol

over TCP/IP. In Magic, we offer similar interfaces like Reflection. This includes terminal

emulation and electronic file transfer. Terminal emulation in Magic supports both VT-MGR and

telnet over TCP/IP. However, Magic does not support the local field validation as supported by

HP native terminal.

MPE Application Access Through HP Terminal Using Visual Magic

2-tier Client/Server Application

Using the VB wizard in Magic, we convert the presentation layer into a Visual Basic application.

Using this framework we convert the single tier MPE legacy application into a two-tier

Client/Server application. The Magic VB wizard generates VB code, which replicates the

presentation of the legacy application exactly in the same way as the dumb terminal. The server

continues to do business processing and logically unaware of the change in the interface in the

presentation layer. The VPlus screens are converted into VB MDI (multi document interface)

forms. As a part of Magic infrastructure we offer an adapter called AACom (Application Adapter

Component) which allows the VB application in the client to communicate to the legacy

application in a seamless fashion. The VB wizard generates a VB project and necessary VB code

to interface with the AACom.
