關於 PowerTCP Emulation for ActiveX

用 VT 和 Telnet 控制項將終端模擬功能構建到您的應用程式中。

PowerTCP Emulation for ActiveX is a component that provides terminal emulation, complete with screen-scraping, advanced graphic fonts, and printing capability. Features include VT320, VT220, VT100,VT52 emulation as well as Telnet, Remote Shell (RSH), Remote execute (REXEC), and Remote login (RLOGIN). Useful for web-enabling legacy systems, automating terminal sessions, and more.

PowerTCP Emulation for ActiveX features:

  • Intuitive On-line Help
  • VT320, VT 220, VT100, VT52
  • Telnet
  • RSH
  • REXEC
  • RLOGIN

Potential Uses/Applications:

  • Web-enable legacy systems with screen mapping
  • Create custom front-end for an Informix system
  • Develop "screen-scraping" applications running canned reports
  • Build a remote console for a Video Bridge
  • Automate terminal sessions and file transfers

Sample Projects:

  • VT320 Emulator -Fully functional VT320 Emulator can be enhanced and deployed royalty free
  • Data Capture - Demonstrates how to use the VT Control with the aid of the Telnet Control to access data from either a local file or a Unix box. Once the file is accessed, it is sent to the VT Control to strip out the escape sequences. The data is then extracted from the VT Control and sent to an Excel application

Benefits & Features:

  • 100% .NET compatible using .NET COM interop, samples included
  • VT ActiveX control emulates VT-52, VT-100, VT-220 and VT-320 terminals, interpreting text and escape sequences to display a screen that can be used interactively (like a regular terminal) or invisibly (to capture reports that can subsequently be “screen-scraped” by your application)
  • Telnet ActiveX control can be used to provide a real-time data source, and supports rlogin, rsh and rexec
  • Display options are set using simple properties
  • Printing of the display is fully supported, as is the printing of postscript files and auto-print (prints each line as it is received)
  • Screen-scraping is achieved by reading the Text property, which returns all the text in the scroll-back buffer as well as the display
  • Graphic characters for box drawing is fully supported
  • Key remapping is easily accomplished with a Keydown event, where key 'substitution' can be used to remap keys
  • Dynamic scroll-back buffer can save hundreds (or thousands) of lines
  • Can be used in BOTH event driven and scripted (blocking) application designs
  • Wrapper classes included for convenient integration into Visual C++

What’s Included: The Emulation for ActiveX installation comes complete with the following:

  • 3 Controls/Objects
  • 7 Full Sample projects
  • 2 ASP/ASP.NET Samples
  • Debug Server for debugging and protocol testing
  • Full MS Help 1.3 Documentation, including examples

What's new in V1.1?

VT emulation is now available in the .NET Framework. Included are Dart's standard PowerTCP Emulation for ActiveX samples translated to Visual Basic.NET which enables developers to create VT terminal applications using any .NET Framework language. Just as we have done with our previous product enhancements, this latest release also includes a new debugging application called the Debug Server. This server application is based upon one of Dart's own internal testing tools and is designed to help developers debug their client-side applications by being able to see the message sent from a client application. Then, a developer can respond to the client application with a customized response message sent from the server. This server application will run on any Windows 32-bit platform and is especially helpful when trying to determine if a problem is code related or connection related.
