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 http://stackoverflow.com/questions/1377152/error-handler-exit-sub-vs-end-sub add a comment| 2 Answers 2 active oldest votes up vote 19 down vote accepted 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 w

I feel like Err.Raise is how I would accomplish what I'll describe below. But, I'm not sure how to implement it in the way I need. If I were to use Err.Raise how would I exit the Sub1-15 first before raising the error code in the main sub? That being said, I have a large Excel VBA project that performs a plethora of different routines. I chose to call all routines from one main routine on error goto for means of later maintenance on the individual routines. I have an On Error handler in my main sub that I would like to have triggered if an error is thrown in any of the routines called from that main routine. Is there a way to: Record the Error type that occurred Error message Sub that raises the error On Error exit that sub to return to the main sub, then Raise the error that just occurred in the other sub so that the NotifyandRepair Error Handler is called? I have the following situation Sub MainSub() On Error GoTo NotifyandCorrect Call Sub1 Call Sub2 ... Call Sub15 Exit Sub NotifyandCorrect: 'Send copy of faulty file, the error code and Sub that caused it 'Then stop macro execution completely End Sub Sub Sub1() On Error Exit Sub1 and raise current Error in MainSub(?) 'Perform data checks End Sub Sub Sub2() On Error Exit Sub2 and raise current Error in MainSub(? 'Modify data groups End Sub Sub Sub15() On Error Exit Sub15 and raise current Error in MainSub(? 'Clean up work End Sub Is there anyway I can avoid having to do something like below for each of Sub1-Sub15? Sub MainSub() On Error GoTo NotifyandCorrect Call Sub1 Call Sub2 ... Call Sub15 Exit Sub NotifyandCorrect: 'Send copy of faulty file, the error code and Sub that caused it 'Then stop macro execution completely End Sub ... ... Sub Sub15() On Error Goto HaltExecution 'Clean up work E
generally put more focus on the coding part and getting the desired result but during this process we forget an important thing i.e. Error handling. Error handling is an important part of every code and VBA On Error Statement is an easy way for handling unexpected exceptions in Excel Macros. A well written macro is one that includes proper exception handling routines to catch and tackle every possible error. Error handling is important because in case of any unexpected exceptions your code doesn’t break. Even if any fatal unexpected error occurs in the code then also you should ensure that the code should terminate gracefully. Definition of VBA On Error Statement: On Error statement instructs VBA Compiler, what to do in case any runtime exception are thrown. Syntax of On Error Statement: Basically there are three types of On Error statement: On Error Goto 0 On Error Resume Next On Error Goto
