Sometimes it's not always clear when a mistake has been made, which means I have to go back through a bunch of queries to find where some div/0 error has taken place, since usually the errors occur silently. I'd like to be able to explicitly look for #Iserror so I

display the Access error message and quit the procedure. Each procedure, then, error number : -2147217900 vba will have this format (without the line numbers): 1 Sub|Function SomeName() 2 On Error GoTo Err_SomeName ' Initialize error handling in access 2013 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: ' Label to http://stackoverflow.com/questions/11565644/ms-access-handling-error 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 7~8 with more detail: Select http://allenbrowne.com/ser-23b.html 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.

Surprisingly though, errors and their properties are relatively unknown to a large part of the development community. To effectively implement error handling error handling in your applications, it is necessary to know the resources that are available when your program encounters an error. Assuming we are working with non-executable programs (.mdb's or .accdb's), the most important thing to understand is the global settings for error trapping in our VBA procedure. Under the "Tools » Options" menu, then on the vba error handling "General" Tab there are three options for error trapping: Break on all errors » Stops code execution when an error is encountered. Break in class module » Stops code execution in class modules only. Break on unhandled errors » Stops code execution only if there is no error handling routine present in the procedure. This is the global setting for error handling. So, if error traps are present in our procedures, they will be ignored if we have specified the "Break on all errors" option. In the following image, we've done just that: There are three important statements in an error handling routine: On Error, Resume and GoTo. Typically, they will appear together at the beginning of a procedure: On Error Resume Next On Error GoTo 0 The "Resume" and "GoTo" statements simply tell VBA what to do when an error is encountered. First, Resume has two primary actions associated with it: Resume Next » Ignores the encountered error and continues execution with the next line of co

Add custom error handling to my Access forms and reports?

When capturing and handling errors, you probably think of the Err object, which stores information about the current run-time error. If a form or report encounters an error, you'll find the information you need in an event — the object's Error event to be exact. By default, Access handles action errors without any help from you. On occasion, you might find you want a little more control. When that's the case, take matters into your own hands by usurping the object's Error event. About the Error event Both forms and reports sometimes generate action errors, such as trying to delete a record protected by referential integrity or trying to add a new record without filling in required fields. When this happens, Access displays a predefined warning message that's usually adequate. But if you prefer, you can take charge of the event and force it to do the following: Inhibit the internal message Display a custom message Redirect the application's flow Using the Error even
