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 checking you do before the real work of your error handling in vba macro 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.

The issue is sometimes the part I'm looking for may not be in that Tab, so http://www.mrexcel.com/forum/excel-questions/473606-visual-basic-applications-error-goto-loop.html I added an "On Error GOTO ErrorHandler2" in my code so that it will skip to the next tab and start the looking process over again. The first time the macro runs the Error Handler work great, but when the Macro Loops to go on to the next tab and finds another Error the ErrorHandler2" dosen't work and I get a Run Time Error. I've been looking for the answer on Google.com, but I can find the answer. I've tried ERR.CLEAR and I can't use "ON Error Resume Next" because I'm working with multiple tabs and it would goof everything up. Dose anyone Know why VBA dose this and/or have a solution? Below is my code: Code: Sub Where_Used() ' ' Where_Used Macro PartCount = 1 Q_Total = 0 Q_GrandTotal = 0 Dim Bomnumber As Integer Dim PartNumber As String 'Text Box where user can enter queried part number. a = InputBox("Enter Part Number You are looking for Below. Make sure it dose not contain any of these symbols : \ / ? * [ ]", "Text Box") If a = vbNullString Then MsgBox ("no value was entered, Please try again.") Exit Sub End If PartNumber

I error handling don't know a lot about error handling and I hope you can help me here. I'm working in Access 2003 with VBA ( I know...stuck in the dark ages with Access here at work lol) I know exactly what is causing the problem...but, I'm unsure what error handler to code to make it work. The logic behind the code is to open an Excel workbook based on a date, import a row of excel cells as a new record in Access, close that workbook, then go to the error handling in next date. But, some times the next day looped doesn't exist as an Excel File. So, I'm trying to tell the code to skip over that date since it doesn't exist, and go to the next date. I have a form where the user enters a from date and to date (These vaules are stored variables "FromDay" and "ToDay". (i.e FromDay = 18 and ToDay = 25) The XL files (not every day will have a file date) Estore Refunds 4-19-2010 Estore Refunds 4-21-2010 Estore Refunds 4-22-2010 Pseudo code For nDays = FromDay to ToDay Step 1 Set Global_XL_Estore_Records = Global_XL_Estore.Workbooks.Open("filepath" & "Estore Refund" & month "-" & ndays & "-" year & ".xls") For 4 to 96 Step 1 ' each step is a row in the worksheet "load XL cells in variables, add new record in access table 'close workbook Next 'go to next workbook xl file Next My problem is that the object Global_XL_Estore_Records = nothing when nDays hits 18, or 20, and throws the error "file cannot be found...blah blah blah" I then either have to click end or debug...bringing me back to the code to fix The code works great when lets say the user puts in 4/21/2010 to 4/22/2010 because those XL files exist at the file path. It's just when the user puts in a date range like 4/15/2010 to4/25/2010 where some files dates exist where other dates don't. Any help or adivse will be great...as this is the best I can remember the code...since it's at work, and I can't bring home work

See our guidelines for contributing to VBA documentation. Errors and Error Handling When you are programming an application, you need to consider what happens when an error occurs. An error can occur in your application for one of two of reasons. First, some condition at the time the application is running makes otherwise valid code fail. For example, if your code attempts to open a table that the user has deleted, an error occurs. Second, your code may contain improper logic that prevents it from doing what you intended. For example, an error occurs if your code attempts to divide a value by zero. If you have not implemented error handling, Visual Basic halts execution and displays an error message when an error occurs in your code. The user of your application is likely to be confused and frustrated when this happens. You can forestall many problems by including thorough error-handling routines in your code to handle any error that may occur. When adding error handling to a procedure, you should consider how the procedure will route execution when an error occurs. The first step in routing execution to an error handler is to enable an error handler by including some form of the On Error statement within the procedure. The On Error statement directs execution in event of an error. If there is no On Error statement, Visual Basic simply halts execution and displays an error message when an error occurs. When a
