VB ZOOM 1.2c1.0 Released

VB-ZOOM is an implementation of ZOOM (Z39.50 Object-Orientation Model) v1.2. (http://zoom.z3950.org/api/zoom-1.2.html)

VB-ZOOM is an ActiveX COMponent written in Visual Basic. This component provides a wrapper to the Yaz toolkit Zoom functions which are available from Index Data (http://www.indexdata.dk/yaz/)

This release corrects a number of bugs. The most important probably being that the ZoomRecord.RawData property can now return a Variant Byte Array datatype, instead of the String data type which is subject to character encoding conversion which can corrupt the original data. Other changes are outlined in http://vb-zoom.sourceforge.net/ChangeLog.html... read more
