It uses the YAZ Toolkit from Index Data to provide the low-level functionality. VB-ZOOM makes it very easy to write simple Z39.50 clients on the Windows platform. It can be used from any language which support ActiveX COM, including Visual Basic, C++, VB Script, Javascript, Delphi, Perl, and probably others. In addition to the basic Z39.50 support, the component has some support for converting the MARC and OPAC record syntaxes into XML, and using XPath to extract data. Of course, the code is open source and freely available for download from SourceForge."
