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.
