Version 2.1

The error processing mechanism is completely reconstructed. Now IBProvider can use OLEDB services to create more detailed description of occurred errors:

• Error collections. Earlier several errors were united into one, which could lead to displaying a very long error message.
• Error parametrization. Earlier the only information, that could be obtained from the object of error, was text description. Now you can get more detailed error description. It is an error code (specific for IBProvider) and parameters. For more details see IErrorRecords interface description.

Since ADO.NET can process only OLEDB-errors, from now IBProvider completely satisfies these requirements.

Technical details

• Error processing is completely based on C++ exceptions. Pay attention that when debugging your applications, debugger can react to the exceptions inside the provider.
• There is a limitation in the provider to a maximum quantity of errors returned in error collection. Due to this a generation of the potentially long errors lists is avoided when such operations as delayed commit in updatable rowsets.

Preferences

• Simplification and cardinal improvement of the provider internal structure.
• General productivity is improved. In particular several fairly complicated error control constructions were removed from data selection operation (fetch).
• Sufficiently significant decrease in size of the provider optimized build.
• Basis for further localization of error messages appeared.

If OLEDB services (forming part of ADODB) are not installed on computer, then the provider will use a standard mechanism of error processing with the use OLE Automation.

New error processing is implemented for both versions of the IBProvider - 1.7.14 and 2.1.

Something else

• At present, in comparison with the free version, we completely changed the entire internal design of the provider. See the list of basic differences here.
• Short-term price-cutting allowed one user of IBProvider to purchase at long last the commercial version. Judging by the archive of correspondence, he awaited 8 months for this event. Although even low-priced IBProvider cost him more expensive than other alternative decisions.
