Public Beta: Delphi 7 dbRTL "size mismatch" fix

By: John Kaster

Abstract: This is a public beta to test a new fix for size mismatch issues in persistent database fields for Delphi 7.

Description of Public Beta

This public beta contains an updated dbrtl.dll for Delphi 7. For further information on this issue, see the article Resolving size mismatch exceptions with the Delphi 7.1 update.

Bugs Fixed/New Features

This resolves issues with both the XML Mapper tool that ships with Delphi 7, and existing applications that have size mismatches among the persistent field definitions and the underlying database schema.
