Call LogError(Err.Number, Err.Description, "SomeName()") Resume Exit_SomeName End Select The Case Else in this example calls a custom function to write the error details to a table. This allows you to review the details after the error has been cleared. The table might be named "tLogError" and consist of: Field Name Data Type Description ErrorLogID AutoNumber Primary Key. ErrNumber Number Long Integer. The Access-generated error number. ErrDescription Text Size=255. The Access-generated error message. ErrDate Date/Time System Date and Time of error. Default: =Now() CallingProc Text Name of procedure that called LogError() UserName Text Name of User. ShowUser Yes/No Whether error data was displayed in MsgBox Parameters Text 255. Optional. Any parameters you wish to record. Below is a procedure for writing to this table. It optionally allows recording the value of any variables/parameters at the time the error occurred. You can also opt to suppress the display of information about the error. Function LogError(ByVal lngErrNumber As Long, ByVal strErrDescription As String, _ strCallingProc As String, Optional vParameters, Optional bShowUser As Boolean = True) As Boolean On Error GoTo Err_LogError ' Purpose: Generic error handler. ' Logs errors to table "tLogError". ' Arguments: lngErrNumber - value of Err.Number ' strErrDescription - value of Err.Description ' strCallingPro

Most developers include adequate error-handling routines in their code, but that might not be enough. Knowing when an error occurs and how often it occurs can be important to resolving the issue and avoiding future errors. Access doesn't track errors, but you can add that functionality to any database. All you need is a table and a little code. Note: Our companion download includes a demonstration database and a several .bas module files you can import into any Access database. Don't cut and paste the code directly from here into an Access module, as the article text contains formatting that will generate errors. The easiest way If you have just one database to maintain and you're its only user, error logging isn't a critical issue because you're around when the error occurs.
