| Library type: |
ActiveX, DLL and VBX |
| Price: |
approx. $400 for the main kit, $600 for the RPC kit |
| Licensing: |
Royalty-free? |
| Commentary: |
The ActiveX and 32-bit DLL versions are sold together. VBX and 16-bit
DLL versions are sold as separate packages.
The package also includes uuencoding/uudecoding support, a license
manager, and a network sniffer.
The license manager allows for trialware and "number of running copies"
types of licensing.
The sniffer apparently only works for programs built with the
library.
The ONC/RPC kit appears not to be dependent on the base package, but
it is clear that it does not include all of the functionality of
the base package. That is, basic networking is available in the RPC
package, but not, for example, MIME support. The RPC kit does include
the network sniffer and the license manager.

| Package: |
Xceed Winsock Library |
| Vendor: |
Xceed |
| Provides: |
Complete Winsock 2 COM wrapper |
| Platform(s): |
Win32 only |
| Library type: |
COM components |
| Price: |
$300 |
| Licensing: |
Royalty-free |
| Commentary: |
This is, at base, a basic network I/O library with a few distinguishing
features. It's a COM component that seems truly targeted at language
independence and a broad range of product types. By contrast,
other COM network I/O libraries focus on trivializing Winsock for
lash-it-together-quickly Visual Basic projects.
The library makes real efforts to be scalable: for example, it provides
transparent overlapped I/O support. It's the sort of library that you
design a program around, knowing that it will scale if the project needs
to go beyond simple network I/O.
Obviously it's no replacement for direct Winsock I/O for those projects
that have truly tight space and speed requirements (high-load web servers,
for example), but it might be a good choice if you need something better
than the truly basic network I/O components out there.
Caveat: I've never tried the library; this is just my distilled
impression from reading their web pages and such.

Shareware and Freeware Products:
| Package: |
ACE |
| Author: |
Douglas Schmidt, et al. |
| Provides: |
Advanced network I/O, CORBA ORB, extensible web server |
| Platform(s): |
Win32, virtually all Unixes, various RTOSes |
| Library type: |
C++ class library |
| Licensing: |
Freeware (details here), with commercial support available. |
| Commentary: |
ACE is the Adaptive Communication Environment, the core component of Dr.
Schmidt's offerings. It started as part of his PhD work, and he's been
more interested in publishing papers on it than making money from it.
It's a very extensive library: hundreds of thousands of lines of code.
There's quite a lot of documentation for it, but sadly nothing on
the order of a good user manual. There's a tutorial that will get you
started, but no reference material to speak of, and the tutorial does
not go very deeply into the system. Dr. Schmidt offers all the papers
he's published on various aspects of ACE and the related projects, but
these are mainly about design elements, rather than teaching one how to
use the library.
In summary, the liberal license, the large user community, and the
scope of the library demands that you at least take a look at it. The
documentation issue means that you'll spend more time reading ACE
examples and ACE source code rather than the ACE tutorial and papers,
but the learning curve isn't vertical.
Two related components are worth noting: The ACE ORB (TAO) and the JAWS
Adaptive Web Server. These are both built on ACE, and are useful items
in their own right.

| Package: |
adns |
| Author: |
Ian Jackson, Tony Finch and Jarle Aasa |
| Provides: |
Advanced DNS lookups |
| Platform(s): |
Win32, Unix |
| Library type: |
C library |
| Licensing: |
GPL |
| Commentary: |
This library allows you to look up all kinds of DNS records (as opposed to
just the A and PTR records Winsock gives you direct access to). It's also
useful because it allows asynchronous lookups. Winsock has asynchronous
DNS lookup functions, but they require window messages to work and
they're somewhat limited.
Beware that this is under the GPL license, which means that if you use
this library, your program will have to be released under the GPL
license as well.

This open-source networking effort is now included with Borland's Delphi
6 and Kylix products. Development continues independently, however, so
you may want to visit this site to get updated versions of your Borland
tool's networking components. Or, if you're using C++Builder, you'll
want to get these now instead of waiting for the next release to include
them.
