Vba Error Handling Best Practices
In VB6 IDE menu Tools->Options select General tab and set Break on unhandled errors only. –wqw Dec 27 '11 at 19:46 thats nice to know u should ve sended that as an answer u know. –Berker Yüceer Dec 28 '11 at 7:09 @Deanna thanks for correcting the title. –Berker Yüceer Dec 30 '11 at 6:42 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote accepted There are several problems with your example, but to answer your question, change your error handler to On Error Resume Next or add an actual error handler, check the err.Number there and decide what action to take. Do While Not somevalue= "" sorgu = "INSERT INTO somedb VALUES('" & somevalue & "')" On Error GoTo est rs.Open sorgu, cnn j = j + 1 Loop est: 'some error handling code I would also suggest moving your GoTo statement to just ahead of your Do statement. As you have it you unnecessarily assign the On Error redirect each time the loop executes. On Error GoTo est Do While Not somevalue= "" sorgu = "INSERT INTO somedb VALUES('" & somevalue & "')" rs.Open sorgu, cnn j = j + 1 Loop est: If err.Number = (unique key error) Resume Next Else MsgBox "An error occurred while inserting records. Error " & CStr(Err.Number) & ", " & Err.Description share|improve this answer edited Dec 27 '11 at 18:02 answered Dec 27 '11 at 17:41 jac 7,17511845 add a comment| Your Answer draft saved draft discarded Sign up or log in

Join them; it only takes a minute: Sign up Excel VBA: On Error Goto statement not working inside For-Loop up vote 7 down vote favorite 1 I'm trying to cycle through a table http://stackoverflow.com/questions/8645539/on-error-statement-doesnt-work-when-an-error-occurs-inside-a-loop in excel. The first three columns of this table have text headings, the rest of them have dates as headings. I want to assign those dates, sequentially, to a Date-type variable, and then perform some operations based on the date To do this I am using a foreach loop on myTable.ListColumns. Since the first three columns do not have date headers, I have tried to set the loop up so that, if there is an http://stackoverflow.com/questions/11998836/excel-vba-on-error-goto-statement-not-working-inside-for-loop error assigning the header string to the date-type variable, the loop goes straight to the next column This seems to work for the first column. However, when the second column's header is 'assigned' to the date-type variable, the macro encounters an error even though it is within an error-handling block Dim myCol As ListColumn For Each myCol In myTable.ListColumns On Error GoTo NextCol Dim myDate As Date myDate = CDate(myCol.Name) On Error GoTo 0 'MORE CODE HERE NextCol: On Error GoTo 0 Next myCol To reiterate, the error is thrown on the second round of the loop, at the statement myDate = CDate(myCol.Name) Can anyone explain why the On Error statement stops working? excel vba excel-vba for-loop error-handling share|improve this question asked Aug 17 '12 at 1:52 Swiftslide 41751828 Rather than using an error as your control structure, maybe an IF with an IsDate function would be more suitable in this scenario? –ray Aug 17 '12 at 2:29 1 If you are "blindly" handling the error - rather than taking specific action on an error type - then you should just use an On Error Resume Next outside your loop. At the moment you are using error handling afresh on each column. –brettdj Aug 17 '12 at 2:40 1 @brettdj, I don't think you can just resume next.

Database Guide User login Username: * Password: * Request new password Home › Tutorials Error Handling In Visual Basic Level: Despite your best efforts to cover all possible contingencies, run-time errors will occur in your applications. You can and should do all you can to prevent them, but when they happen you have to handle them. Introduction Trapping Errors at Run-Time Building Error Handlers Raising Your Own Errors Summary Introduction The various functions, statements, properties and methods available in Visual Basic and the components used in Visual Basic expect to deal with certain types of data and behavior in your applications. For example, the CDate() function can convert a value to a Date variable. The function is remarkably flexible in the type of information it can accept, but it expects to receive data that it can use to derive a date. If you provide input that it can't convert, it raises error number 13 - "Type mismatch" - essentially saying "I can't handle this input data." In an application, this type of error may be a program logic error (you simply passed the wrong data) or it may be a data entry error on the part of the user (you asked for a date and the user typed a name). In the first case, you need to debug the program to fix the mistake. However, there is no way for you to anticipate the behavior of the end users of the application. If the user enters data you can't handle, you need to deal with the situation. Dealing with errors at run-time is a two step process: Trap the Error Before you can deal with an error, you need to know about it. You use VB's On Error statement to setup an error trap. Handle the Error Code in your error handler may correct an error, ignore it, inform the user of the problem, or deal with it in some other way. You can examine the properties of the Err object to determine the nature of the error. Once the error has been dealt with, you use the Resume statement to return control to the regular flow of the code in the application. In addition to dealing with run-time errors, you may at times want to generate them. This is often done in class modules built as components of ActiveX server DLLs or EXEs. It is considered good programming practice to separate the user interface from the program logic as much as possible, so if a server component cannot deal with an error, it should raise the error in its client application rather than simply display an error message for the user. In VB5, there is an option that allows you to specify that an application has been designed for unattended execution (this is typically used for
