Introduction

MWA Software was originally best known as a supplier of JPEG, GIF and Text Editing software components for Borland's Delphi and C++Builder Development Tools. We also supply a general purpose text editor ideal for editing very large text files, and distributed Merge Modules for the Firebird RDMS (now a legacy product). We also develop bespoke database and real time software solutions.

IBX for Lazarus is a version of IBX ported to the Lazarus IDE by MWA Software.

MWA Software was launched in 1996 and is the software development division of McCallum Whyman Associates Ltd (MWA).

 

IBX 2.7.0 for Lazarus is now available for download

MWA Software is pleased to announce the release of version 2.7.0 of IBX for Lazarus. This is primarily a maintenance release but does contain some important future proofing. All users are recommended to upgrade to this version.

In this release:

  • Firebird 5 compatibility checked
  • Lazarus 3.4 compatibility checked
  • Internal changes necessary to correctly function with FPC 3.3.1 (development version) and later.
  • Dynamic Database Controls Direct Dependency on IBX  removed and replaced with corba interfaces.
  • Various bug fixes - see changelogs of IBX and the Firebird Pascal Interface for details.

The changes to the Dynamic Database Controls are intended to enable their use with database drivers other than IBX. Other developers are encourage to support the corba interfaces defined in their support so that their full functionality is available generally. See the new document "DynamicDatabaseControls.pdf" for further information.

IBX for Lazarus 2.6.3 is now available for download

MWA Software is pleased to announce the release of version 2.6.3 of IBX for Lazarus.

This version focuses primarily on improved testing and documentation for the handling of international single byte character sets. It includes several fixes for handling international character sets. Users of international character sets (other than UTF8) should read the opening remarks of Chapter 9 of the Firebird Pascal API Guide for guidance on the inclusion of FPC RTL units to ensure full support, and the new section 9.8 on Firebird Exceptions.

This version has also been tested with Lazarus 3.0RC2 and includes fixes in some example programs for compatibility with the latest version of Lazarus. Specifically using the "NullDate" constant instead of assuming that NullDate has a value of zero.

Version 2.6.3 is no longer labelled as Beta.

IBX 2.6.0 beta is now available for download

MWA Software is pleased to announce the release of version 2.6.0 of IBX for Lazarus.

This version features a complete rewrite of internal buffer management in order to improve performance
and maintainability. Highlights:

  •  Extending the size of the buffer pool no longer has to copy the entire record
    cache. Instead, a new extent is simply added to the buffer pool.
  •  A memory to memory copy of each display buffer now is avoided when scolling the
    dataset.
  •  A separate set of buffers is now used for calculated fields. This avoids
    having to keep copies of calculated field values in the buffer cache.
  • Compact bitmaps are used to record null status and need to refresh in each
    buffer.
  •  Display buffer type changed from PChar to TRecordBuffer in line with change of
    buffer type in FCL-DB.

There are also several bug fixes.

This version has passed all regression tests. However, it will benefit from wider field testing and is hence labelled as a beta release. Please conduct your own testing before considering its use in production software.

NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED AS BETA SOFTWARE.
