Creating custom encoding schemes

You can implement a custom encoding scheme by building a custom encoding DLL. You could use this DLL to apply special features required for a particular messages system, or to collect statistics, such as how many messages or how many bytes were sent to each user.

The header file dbrmt.h, installed into the h subdirectory of your installation directory, provides an application programming interface for building such a scheme.

To instruct SQL Remote to use your DLL for a particular message system, you need to set a message control parameter called encode_dll to a value that is the full path to the custom DLL you have created. For example:

SET REMOTE ftp OPTION "Public"."encode_dll" = 'c:\\sany11\\Bin32\\custom.dll';
Encoding and decoding must be compatible

If you implement a custom encoding, you must make sure that the DLL is present at the receiving end, and that the DLL is in place to decode your messages properly.
