Error Handling Parameters

This topic contains parameters that are used for error handling.

JET_paramErrorToString 70

This parameter can be used to convert a JET_ERR into a string. This is done using a special call to JetGetSystemParameter where the integer output buffer contains the JET_ERR value to be converted (as an input parameter) and the string output buffer returns the matching error string. The string will look something like this: "JET_errSuccess,Successful Operation". The string is composed of the symbolic name for the string, then a comma, and then a simple text description of the error. The description string may itself contain commas. If the error is not recognized then the string will be "Unknown Error,Unknown Error".

Note  This parameter is read only.

JET_paramExceptionAction
98

This parameter controls what happens when an exception is thrown by the database engine or code that is called by the database engine. When set to JET_ExceptionMsgBox, any exception will be thrown to the Windows unhandled exception filter. This will result in the exception being handled as an application failure. The intent is to prevent application code from erroneously trying to catch and ignore an exception generated by the database engine. This cannot be allowed because database corruption could occur. If the application wishes to properly handle these exceptions then the protection can be disabled by setting this parameter to JET_ExceptionNone.
