Encoder/X

- Version 1.00.009

Encoder/X provides an easy and powerful way to handle
the data encoding formats used by various Internet
protocols. There are four encoding types used by
protocols such as mail and news, Base64, BinHex 4.0,
Quoted-Printable, and UU. Encoder/X provides a number
of functions to convert back and forth between binary
(or text) data and any of those formats.
Encoder/X provides unlimited flexibility when it comes
to specifying source and destination for the data
being encoder or decoded. The following methods
fulfill basic requirements: FileToString, FileToFile,
StringToFile, and StringToString. In addition to that
Encoder/X utilizes our new Stream/X technology to
provide a fully extensible way of accessing and
storing encoded/decoded data.
Our Streams/X objects include the following:
MemStream, VirtualMemStream, and FileStream. Any of
those can be used by Encoder/X's StreamToStream
method. And there are StreamToFile, StreamToString,
FileToStream, and StringToStream methods. If, for
instance, you have a file containing a huge amount of
data to be decoded you could create a VirtualMemStream
and then use the FileToStream method to decode the
data. Using this technique you can easily access
many tens of megabytes of decoded data.
Streams/X also exports an interface call IMStream.
The IMStream interface is simple, consisting of a
handful of functions such as Seek, Read, and Write.
IMStream was designed with Visual Basic in mind so it
is easy for programmers to create their own classes
using Visual Basic that can easily perform tasks such
as decoding data directly out of a database field into
a string.
Encoder/X also makes use of the IMStream interface.
The Encoder and Decoder objects Implement the IMStream
interface, and each of them has an In property to
which an IMStream object can be assigned. This makes
it easy to perform a number of conversion jobs. For
instance, if you need to convert UU encoded data
stored in a file to Base64 in memory you could do
