Join them; it only takes vba iferror a minute: Sign up Error Handler - Exit Sub vs. End Sub up vote 13 down vote favorite 1 Why would I want to get out of an Error Handler (after handling) with an Exit Sub instead of just letting https://msdn.microsoft.com/en-us/library/5hsw66as.aspx it go to the End Sub? I'm sure it's simple. I just don't understand. Thanks for any help. Example: Public Sub SubA() On Error Goto ProcError ''# other code MsgBox FuncA() ProcExit: Exit Sub ProcError: MsgBox Err.Description Resume ProcExit End Sub vba vb6 error-handling share|improve this question edited Sep 4 '09 at 12:06 AnthonyWJones 144k22195274 asked Sep 4 '09 at 3:53 RNamo add a comment| 2 Answers 2 active oldest votes up vote 19 down vote accepted Your ProcExit label is your http://stackoverflow.com/questions/1377152/error-handler-exit-sub-vs-end-sub place where you release all the resources whether an error happened or not. For instance: Public Sub SubA() On Error Goto ProcError Connection.Open Open File for Writing SomePreciousResource.GrabIt ProcExit: Connection.Close Connection = Nothing Close File SomePreciousResource.Release Exit Sub ProcError: MsgBox Err.Description Resume ProcExit End Sub share|improve this answer answered Sep 4 '09 at 5:08 AngryHacker 23.1k60199387 1 +1. And, obviously, if you don't need to close or release any resources, there's no need for it and you can just fall through to the End Sub. –MarkJ Sep 4 '09 at 8:16 @MarkJ: Thats probably Ok but I'd be uncomfortable with that, If the error has truely been "handled" I'd prefer to Resume to ProcExit even if its immediately followed with Exit Sub. –AnthonyWJones Sep 4 '09 at 12:05 7 Wouldn't this cause an infinite loop if something below ProcExit raises an error? –Mike Spross Sep 5 '09 at 7:19 add a comment| up vote 1 down vote Typically if you have database connections or other objects declared that, whether used safely or created prior to your exception, will need to be cleaned up (disposed of), then returning your error handling code back to the ProcExit entry point will allow you to do your garbage collection in both cases. If you drop out of your procedure by falling to Exit Sub, you may risk having a yucky build-up of instantiated objects that are just sitting around in your prog
three flavors: compiler errors such as undeclared variables that prevent your code from compiling; user data entry error such as a user entering http://www.cpearson.com/excel/errorhandling.htm a negative value where only a positive number is acceptable; and run time errors, that occur when VBA cannot correctly execute a program statement. We will 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 code in this on error 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 names are defined. The more vba on error 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 Sub, Exit Function, or Exit Property. The term end statement
