DELPHI RAS COMPONENT

DELPHI RAS COMPONENT - version 3.0 - 28th March 1999 ===================================================== (C) 1996 Daniel Polistchuck and 1999 Magenta Systems Ltd This is a Delphi 2.0 wrapper for the RAS & W95 Dial-Up Connection client services. It was tested and re-tested. This component is a rewrite of the excelent Mike Armstrong's TRAS component. Parts of it were rewritten in order to conform to the 32 bits RAS Api, whose prototypes are included in the RAS_API32 unit source code. Daniel Polistchuck with collaborations from Ronaldo Smith Jr. ------------------------------------------------------------------------------ Updated by Angus Robertson, Magenta Systems Ltd, England in early 1999, delphi@magsys.co.uk, http://www.magsys.co.uk/delphi/ Compatible with Delphi 2, 3 and 4, Windows 95, 98 and NT 4.0. TRAS is an installable Delphi non-visual component, supplied with full source and a demo program, for accessing Dial Up Networking or Remote Access Services functions. This is an updated version of Daniel Polistchuck's and Mike Armstrong's earlier component. It adds support for phone books including DUN password update, using existing connections, NT compatible, improved events and progress messages, on demand DLL loading to allow application use without RAS installed, connection IP addressed, performance statistics for Win95/98/NT showing data transmitted and received. A new demo program illustrates nearly all the methods and properties. By using TRAS, it is not necessary to understand any of the RAS APIs or structures. Since TRAS does need design time properties, it need not really be installed as such, but may be created in the application as needed, as shown in the demo program. Known Problems -------------- Please note that getting performance statistics from Windows 95/98 can sometimes be difficult. This component now searches the registry for any Dial-Up Adaptors and will default to the first found. If there are two or more adaptors installed, I'm not currently sure how to determine which is being used, but a list is returned and a property may be changed to select one. To get performance statistics running, make sure that Connection Properties, Server Types, Record a Log File is ticked, and in Modem Properties, Options, Display Modem Status is ticked. You may need to reboot after these changes and then make a connection, at which point the correct registry keys should be created. Users have reported difficulties geting performance statistics from DUN version earlier than 1.2, so this is recommended. TAPI Functions -------------- Note that Magenta Systems also has available some TAPI functions that allow monitoring on modems and ISDN adaptors using events, avoiding needing to continually poll using the RAS APIs. TAPI also monitors non-RAS modem usage and will monitor incoming calls. A TAPI function is also used to convert the canonical telephone number into a dialable number according to telephony dialling properties. See the web site listed above for more details on the TAPI functions. Distribution ------------ TRAS may be freely distributed via web pages, FTP sites, BBS and conferencing systems or on CD-ROM in unaltered zip format, but no charge may be made other than reasonable media or bandwidth cost. TRAS may be used freely in Delphi applications, but it would be polite to mention in the documentation that your application is using "TRAS from Daniel Polistchuck and Magenta Systems Ltd". Please email Magenta Systems Ltd at delphi@magsys.co.uk if you use TRAS in some way, so you can be notified of upgrades or other important changes. Magenta Systems Ltd uses TRAS in its DUN Manager and CamCollect applications that may be found at http://www.magsys.co.uk/ so if you want to support the effort that has gone into enhancing and testing this component, please look at one or both of those applications and register them.
