between 'on error goto 0' and 'on error goto -1' — VBA up vote 21 down vote favorite 9 Can anyone find the difference between 'On error goto -1' and 'on error goto 0' in VBA? I've tried google and msdn, but I've had no luck. excel vba msdn share|improve this question asked Jan 4 '13 at 14:22 sterlingalston 155116 This vba error handling best practices documentation is for Visual Basic, not VBA, but the concepts are similar enough in this case that it should explain the difference. –vcsjones Jan 4 '13 at 14:30 add a comment| 4 Answers 4 active oldest votes up vote 33 down vote accepted On Error GoTo 0 disables any error trapping currently present in the procedure. On Error GoTo -1 clears the error handling and sets it to nothing which allows you to create another error trap. Example: On Error GoTo -1 After the first error is raised, it will GoTo ErrorFound which will then clear the routine's error handling and set a new one, which will GoTo AnotherErrorFound when an error is found. Sub OnErrorGotoMinusOneTest() On Error GoTo ErrorFound Err.Raise Number:=9999, Description:="Forced Error" Exit Sub ErrorFound: On Error GoTo -1 'Clear the current error handling On Error GoTo AnotherErrorFound 'Set a new one Err.Raise Number:=10000, Description:="Another Forced Error" AnotherErrorFound: 'Code here End Sub Example: On Error GoTo 0 After the first error is raised, you will receive the error as error handling has been disabled. Sub OnErrorGotoZeroTest() On Error GoTo 0 Err.Raise Number:=9999, Description:="Forced Error" End Sub s

Vba Error Handling In Loop
user entering a negative value where only a positive number is vba iferror acceptable; and run time errors, that occur when VBA cannot correctly execute a program statement. We will iserror vba concern ourselves here only with run time errors. Typical run time errors include attempting to access a non-existent worksheet or workbook, or attempting to divide by zero. The example http://stackoverflow.com/questions/14158901/difference-between-on-error-goto-0-and-on-error-goto-1-vba code in this article will use the division by zero error (Error 11) when we want to deliberately raise an error. Your application should make as many checks as possible during initialization to ensure that run time errors do not occur later. In Excel, this includes ensuring that required workbooks and worksheets are present and that required http://www.cpearson.com/excel/errorhandling.htm names are defined. The more checking you do before the real work of your application begins, the more stable your application will be. It is far better to detect potential error situations when your application starts up before data is change than to wait until later to encounter an error situation. If you have no error handling code and a run time error occurs, VBA will display its standard run time error dialog box. While this may be acceptable, even desirable, in a development environment, it is not acceptable to the end user in a production environment. The goal of well designed error handling code is to anticipate potential errors, and correct them at run time or to terminate code execution in a controlled, graceful method. Your goal should be to prevent unhandled errors from arising. A note on terminology: Throughout this article, the term procedure should be taken to mean a Sub, Function, or Property procedure, and the term exit statement should be taken to mean Exit S

Starten Sie unbedingt mit dem Anfang, also mit : Fehlerbehandlung (0) - Einführung On Error Goto und Err VBA stellt uns verschiedene Möglichkeiten zur Verfügung, auf abfangbare Laufzeitfehler zu reagieren. Wenn wir dies tun, muss uns bewusst sein, dass für VBA damit der Fehler bearbeitet ist und wir frisch fröhlich unseren zusammengestrickten on error goto Code weiter ausführen lassen. Wir sind dafür verantwortlich, wie das Programm danach weiterarbeiten soll. Aber beginnen wir mit einem einfachen Beispiel: Public Sub Fehler0() Dim i As Long, k As Long i = 3 / k End Sub Klar - oder, dies produziert einen Fehler mit einer Meldung von VBA und fertig ist die Geschichte - ähh das Programm. Sehr unschön für den Anwender und auch für unser Programm, sofern wir da noch mehr dahinter stehen haben. Wir wollen dies nun ein klein wenig verändern: Public Sub Fehler0() Dim i As Long, k As Long On Error GoTo Fehler i = 3 / k Exit Sub Fehler: MsgBox "Da war ein Fehler" End Sub Hier kontrollieren wir selbst den Fehler. Aber schauen wir uns das im Einzelnen an: On Error Goto Fehler: Dies bedeutet für VBA, dass es bei einem Laufzeitfehler zu der Sprungmarke Fehler: gehen soll. Eine Sprungmarke kann ich nennen wie ich will, solange sie den Regeln für Bezeichner gehorcht. Also ich kann diese

These best practices will help ensure your apps run as intended, without a hitch. By Susan Harkins | in Five Apps, October 9, 2010, 1:15 AM PST RSS Comments Facebook Linkedin Twitter More Email Print Reddit Delicious Digg Pinterest Stumbleupon Google Plus A professional application always includes adequate error-handling routines to trap unexpected errors. Sometimes, the right handling means the user never knows the error occurred. At the very least, error-handling routines should address the problem, share adequate information on what the user should do next, and exit the program (if absolutely necessary) gracefully. You put a lot of effort into writing the procedures that run your custom applications. Why let a runtime error ruin it all? By employing a few best practices, you can improve error handling. 1: Verify and configure error settings Before you do anything, check the error-trapping settings. VBA, via the Visual Basic Editor (VBE), is flexible and allows you to determine how it responds to errors. To access these settings (shown in Fi
