Ms Access Error Handling Best Practice
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 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

In particular, what should I do in this situation: ... some code ... ... some code where an error might occur ... ... some code ... ... some other code where a different error might occur ... ... some other code ... ... some code that must always be run (like a finally block) ... I want to handle both errors, and resume execution after the code where the error http://stackoverflow.com/questions/1038006/good-patterns-for-vba-error-handling may occur. Also, the finally code at the end must ALWAYS run - no matter what exceptions are thrown earlier.

Errors in the error handling routine are terminating. The range 513-65535 is available for user errors. For custom class errors, you add vbObjectError to the error number. For not implemented interface members in a derived class, you should use the constant E_NOTIMPL = &H80004001. Option Explicit Sub HandleError() Dim a As Integer On Error GoTo errMyErrorHandler a = 7 / 0 On Error GoTo 0 Debug.Print "This line won't be executed."

a full version of Access, while a run-time version just crashes. For a more detailed approach to error handling, see FMS' article http://allenbrowne.com/ser-23a.html on Error Handling and Debugging. The simplest approach 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 vba error ' Exit before error handler. 6 Err_SomeName: ' Label to jump to on error. 7 MsgBox Err.Number & Err.Description ' Place error handling here. 8 Resume Exit_SomeName ' Pick up again and quit. 9 End Sub|Function For a task where several things could go wrong, lines 7~8 will be replaced with more detail: Select Case Err.Number Case 9999 ' Whatever vba error handling number you anticipate. Resume Next ' Use this to just ignore the line. Case 999 Resume Exit_SomeName ' Use this to give up on the proc. Case Else ' Any unexpected error. 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 displa
