The Inventu Viewer+ is a family of software components designed to optimally connect between the old (terminal-based applications) and the new (web, web services, .NET applications) by leveraging the power and reliability of Microsoft Windows Server and .NET technologies.

 

Pure and Secure Web-Based Terminal Emulation

 

The centrally managed Inventu FVTerm web application delivers secure, instant access to users without requiring any installation or plug-ins.  All functionality is implemented using HTML and Javascript with support for older browsers as well as touch-enabled device platforms such as the iPad, Android Tablets and the Microsoft Surface RT and Pro.

 

 Features Include:

 

•Has no installation delay--users are instantly running with no downloads and no Java or ActiveX plugins required

•Supports the latest and most secure Security, SSL and user identity technologies as implemented by Microsoft's Internet Information Server (IIS)

•Full Keyboard buffering - can key ahead of host response times

•Comprehensive Javascript Interface - Enables hosting in other web applications while integrating with data when needed

•Full feature Macro Recording and Scripting - Macros are saved centrally and shared between users

 

 

A Low Cost, High Value Kit for Integrating and Leveraging Terminal-Based Applications

 

Inventu Viewer+ provides organizations with an easily implemented solution for re-use of existing application logic "locked-up" in screen-based applications.  It does this through an approach that is based on decades of experience in screen integration technology.  With its high value and low cost, starting with analysis on through to full life-cycle maintenance, Inventu Viewer+ is the easiest purchase decision available in the terminal emulation market.

 

Using Inventu Viewer+, developers can create a wide variety of valuable, reusable application components within an organization, such as:

 

•Inquiry transactions (inventory on-hand for Web-based order-entry system)

•Update transactions (health insurance claims entry)

•User interface renovation (new graphical user interface for an application subset)

 

Only What you Need Without the Confusing Extras

 

The Inventu Viewer+ components are focused on the process of integrating screen-based applications with contemporary web and .NET clients and solutions.  Unlike many products available today, Inventu Viewer+ does not try to "integrate with everything" nor does it include any features or tools unrelated to screen interfacing (such as ODBC database access).

 

This keeps product pricing low while minimizing the learning curve for new developers and fully leverages your existing development infrastructure.

 

High Performance Coupled with Powerful Interface Features

 

Key to success of a server-based emulation product is that it succeed at its job without slowing things down.  In addition, the product can't be a "pig" on resources.  Through the use of time-tested C and C++ algorithms and techniques, Inventu Viewer+ performs at the top of its emulation class which enables it to be added to existing application server farms at minimal cost.

 

In designing the interfaces for the developer, careful attention was paid to minimizing the number of "core" methods required to create robust applications while "packaging" as much functionality as possible in each method.  As a result, developers can quickly produce callable routines that navigate the most screens with the least amount of code.

 

Minimizing Development Mystery

 

Inventu Viewer+ comes with a full set of diagnostic and administration tools that uncloak many of the mysteries involved in screen interface construction and management.  The Screen Workflow Screen Recorder and Viewer helps close the gap between users that know how the screen applications work and the analysts and developers that need to build interfaces to those screens.  The Inventu Viewer Studio provides visual editing of screen definitions used for recognition, data mapping and full Visual Studio Solution code generation (web services, ASP.NET user interfaces and a scriptable SharePoint web part).  The Administrator's Window provides live heartbeat information on the health and activity of the host sessions while the Trace Viewer provides full details on the interaction between the host applications, active screens and the developer API's that are at work on those screens.

 

This comprehensive set of documentation, analysis and diagnostic tools ensure that screen interfacing transactions are rapidly scoped, implemented and managed with minimal "head scratching".

 

Powerful Developer Productivity

 

The optional Inventu Viewer Studio helps identify screens, map fields, design web services and design modernized screens.  A sophisticated code generation framework converts your screen recordings and definitions into complete Visual Studio Solutions (works with free versions of Visual Studio Express) including:

 

•Full Function Web Services for data entry or inquiry

•Support for generating OpenAPI SWAGGER-based API's for interfacing to modern web development environments

•Ready to edit complete Visual Studio Solutions supporting versions 2003 through Visual Studio 2019 and .NET 4.0 through .NET 4.7

•Support for Windows Communication Foundation publishing and WCF clients

•Modernization and Migration:  screens published as ASP.NET web pages in portions, or combined

•Direct support for Javascript / jQuery clients using WCF REST-JSON publishing
