Events Generated by the ODBC Driver Manager

  • Article

Important

Support for Visual Studio Analyzer was removed beginning in Windows 8 (Visual Studio Analyzer was only included in older versions of Visual Studio.). For an alternative troubleshooting mechanism, use BID tracing.

Events generated by the ODBC Driver Manager are registered when the Start Visual Studio Analyzer button is clicked. The tool itself offers system-defined events and the ability to create custom events. For more information about events, see the Visual Studio Analyzer Reference Guide within the Visual Studio suite of documentation.
