ACTIVESOCKET 3.0 RELEASE NOTES

INTRODUCTION

ActiveSocket 3.0 is the newest version of the ActiveSocket Network Communication Toolkit. The mission of the product is to provide a collection of useful network communication tools for a variety of development platforms.

WHAT'S NEW IN ACTIVESOCKET 3.0

- Constants -

  • Constants are now defined in a separate class called 'ASConstants'. The use of a separate constants class makes your code better readable and maintainable.

- Snmp -

  • New SNMP classes. The ActiveSocket 2.4 'Snmp' object doesn't exist anymore; instead, two new objects are introduced: 'SnmpManager' and 'SnmpData'. The 'SnmpManager' object is used to connect to the remote SNMP manager. The 'SnmpData' object encapsulates a single SNMP data object;
  • In previous versions of ActiveSocket, the 'Set' operation didn't work for identifiers of type 'IPAddress'. This has been fixed in v.3.0.

- Snmp Traps -

  • New SNMP Trap classes. The ActiveSocket 2.4 'SnmpTrapIn' and 'SnmpTrapOut' objects don't exist anymore; instead, two new objects are introduced: 'SnmpTrapManager' and 'SnmpTrapData'. The 'SnmpTrapManager' object is used to connect to the remote SNMP manager and send or receive SNMP trap data. The 'SnmpTrapData' object encapsulates a single SNMP trap data object;
  • You can now see the sender of a trap when a trap is received. The IP address of the sender is part of the SnmpTrapData object;
  • In previous versions of ActiveSocket, traps where received from any community, regardless of which community was specified. This has been fixed in v.3.0;
  • ActiveSocket now supports SNMP v.1 trap types. The following generic SNMP v.1 trap types are supported: Cold Start, Warm Start, Link Down, Link Up, Authentication Failure, Neighbor Loss and User Specific.

- Socket -

  • The 'Socket' object now automatically detects a broken connection. The ConnectionState property is set to asSOCKET_CONNSTATE_DISCONNECTED when the connection is beroken, for instance because the remote TCP/IP party initiated a disconnect. In previous versions of ActiveSocket, a disconnect was not detected;
  • The SendString function now only takes one parameter, and sends a carriage return/line feed automatically. If you don't want to send a carriage return/line, use the SendBytes function. In previous versions of ActiveSocket, the SendString function required a second parameter to specify whether or not to send a carriage return/line feed;
  • You can now specify a maximum buffer size for a receive cycle. The default buffer size is 16KB, which means that no more than 16K is received by a ReadString or ReadBytes operation (i.e. you need to call ReadString or ReadBytes twice to receive all data);

- New protocol supported: Ftp -

  • ActiveSocket now supports FTP, featuring: Anonymous login, login using username and password, binary- and ascii up/download of files, passive/active mode and more.

- Licensing -

  • Licensing of ActiveSocket has changed. There are now 3 different license schemes:

    1. Standard License (#AX001-0010) - Allows you to use the following objects only: Icmp, Http, Ftp, Socket and ASConstants;
    2. Professional License (#AX001-0012) - Allows you to use all objects: Icmp, Http, Ftp, Socket, Dns, Ntp, Rsh, SnmpManager/SnmpData, SnmpTrapManager/SnmpTrapData, WOL and ASConstants;
    3. Distribution License (#AX001-0020) - Allows you to use all objects; Allows you to Rent, lease or distribute an unlimited number of licenses of the software outside your organization bundled with an application.
