See our guidelines for contributing to VBA documentation. Errors and Error Handling When you are programming an application, you need to consider what happens when an error occurs. An error can occur in your application for one of two of reasons. First, some condition at the time the application is running makes otherwise https://msdn.microsoft.com/en-us/library/office/ff193267.aspx valid code fail. For example, if your code attempts to open a table that the user has deleted, an error occurs. Second, your code may contain improper logic that prevents it from doing what you intended. For example, an error occurs if your code attempts to divide a value by zero. If you have not implemented error handling, Visual Basic halts execution and displays an error message when an error occurs in your code. The user of your application is likely to be confused and frustrated when this happens. You can forestall many problems by including thorough error-handling routines in your code to handle any error that may occur. When adding error handling to a procedure, you should consider how the procedure will route execution when an error occurs. The first step in routing execution to an error handler is to enable an error handler by including some form of the On Error statement within the procedure. The On Error statement directs execution in event of an error. If there is no On Error statement, Visual Basic simply halts execution and displays an error message when an error occurs. When an error occurs in a procedure with an enabled error handler, Visual Basic does not display the normal error message. Instead it routes execution to an error handler, if one exists. When execution passes to an enabled error ha
user may be left viewing the faulty code in a full version of Access, while a run-time version just crashes. The simplest approach http://allenbrowne.com/ser-23b.html is to display the Access error message and quit the procedure. Each procedure, then, will have this format (without the line numbers): 1 Sub|Function SomeName() 2 On Error GoTo Err_SomeName ' Initialize error handling. 3 ' Code to do something here. 4 Exit_SomeName: ' Label to resume after error. 5 Exit Sub|Function ' Exit before error handler. 6 Err_SomeName: error handling ' Label to jump to on error. 7 MsgBox Err & " " & Error$ ' Place error handling here. 8 Resume Exit_SomeName ' Pick up again and quit. 9 End Sub|Function The labels (lines 4 and 6) must be in the current procedure, and must be unique. For a task where several things could go wrong, replace lines vba error handling 7~8 with more detail: Select Case Err Case 9999 ' Whatever number you anticipate. Resume Next ' Use this to just ignore the line. Resume Exit_SomeName ' Use this to give up on the proc. Case Else ' Any unexpected error. Call LogError(Err, Error$, "SomeName()") Resume Exit_SomeName End Select The Case Else in this example calls a custom procedure 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 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. Below is the procedure for writing to this table. If you wish to go further, you could extend it to count errors recorded recently and suppress the display of the same message repeatedly, or give up retrying locking errors. Sub Log
