Vba Error Handling Best Practices

Or perhaps you could tell me how to "better vba on error goto 0 write" the following macro so I don't get an error at all. I have a list of cells with numbers and what the macro does is insert "x" number of rows based on whatever the number is in the row (above) the active cell. For example: A1 = 8 A2 = 2 A3 = 5 A4 = 3 below A4 3 rows are inserted, below A3 5 rows are inserted, etc. The macro works from the bottom up but errors out when it gets to the top (A1): Sub FormatForm() Range("A1").End(xlDown).Offset(1, 0).Activate Do Until ActiveCell = "A1" ActiveCell.Offset(-1, 0).Activate Dim i As Integer For i = 1 To ActiveCell.Offset(-1, 0).Value ActiveCell.EntireRow.Insert Next Loop End Sub I'm sure it has something to do with my Do Until or maybe I need an Error On statement, but not quite sure. Help would be appreciated!

Join them; it vba on error msgbox only takes 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 http://www.mrexcel.com/forum/excel-questions/58276-exit-sub-error.html of just letting 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 145k22195274 asked Sep 4 '09 at 3:53 RNamo add a comment| 2 Answers 2 active oldest votes up vote 19 down vote accepted http://stackoverflow.com/questions/1377152/error-handler-exit-sub-vs-end-sub Your ProcExit label is your 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 23.2k60200387 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
three flavors: compiler errors such as undeclared variables that prevent your code from compiling; user data entry error such as a user entering a negative value where only a positive number is acceptable; and run time errors, that occur when VBA cannot correctly execute a program http://www.cpearson.com/excel/errorhandling.htm statement. We will concern ourselves here only with run time errors. Typical run time errors include attempting https://bytes.com/topic/access/answers/193185-how-exit-sub-error to access a non-existent worksheet or workbook, or attempting to divide by zero. The example 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 on error worksheets are present and that required 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 on error goto 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 should be taken to mean End Sub , End Function, End Property, or just End. The On Error Statement The heart of error handling in VBA is the On Error statement. This statement instructs VBA what to do when an run time error is encountered. The On Error statement takes three forms. On Error Goto 0 On Error Resume Next On Error Goto
