Some of the results are "#N/A" and there will be a green triangle on the left top of the cell. I want to remove the green triangle (ignore the error) automatically, but the "#N/A" result should be remained, just remove the green triangle. Anyone knows how to do this? Thanks in advance. excel vba share|improve this question asked Mar 5 vba on error goto 0 '14 at 9:08 user2774993 2717 add a comment| 4 Answers 4 active oldest votes up vote 1 down vote If you want the green triangle to go away you need to set the Error.Ignore property to true. For example, if you have a formula such as "=1/0" in cell A1, then in VBA you could do something like this: Dim r as Range Set r = Range("A1") r.Errors.Item(1).Ignore = True And the green triangle will go away. share|improve this answer answered Mar 5 '14 at 9:28 steveo40 781410 Thanks for your reply! I tried your method, but returned "Application not-defined" error...@steveo40 –user2774993 Mar 5 '14 at 9:38 If you copy the code exactly into a new sub and pop the dodgy formula into cell A1 it should work fine. (Do it in a new workbook.) –steveo40 Mar 5 '14 at 9:58 Is that the Item(1) means that there is one cell selected? @steveo40 –user2774993 Mar 6 '14 at 2:17 add a comment| up vote 1 down vote You can use below formula: =IFERROR(VLOOKUP([Your Value], [Your Range], [Your Column], FALSE), NA()) share|improve this answer answered Mar 5 '14 at 9:36 StanFish 3571412 add a comment| up vote 1 down vo

a positive number is acceptable; and run time errors, that occur when vba on error exit sub 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 article will use the division by zero error (Error 11) http://stackoverflow.com/questions/22193118/excel-macro-ignore-error 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 application begins, the more stable your http://www.cpearson.com/excel/errorhandling.htm 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 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.
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 http://www.exceltrick.com/formulas_macros/vba-on-error-statement/ 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 http://www.functionx.com/vbaexcel/Lesson26.htm 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 on error gracefully.

the wrong time. The application may crash. A calculation may produce unexpected results, etc. You can predict some of these effects and take appropriate actions. Some other problems are not under your control. Fortunately, both Microsoft Excel and the VBA language provide various tools or means of dealing with errors. Practical Learning:Introducing Error Handling Open the Georgetown Dry Cleaning Services1 spreadsheet and click the Employees tab Click the Payroll tab Click the TimeSheet tab To save the workbook and prepare it for code, press F12 Specify the folder as (My) Documents In the Save As Type combo box, select Excel Macro-Enabled Workbook Click Save Introduction to Handling Errors To deal with errors in your code, the Visual Basic language provides various techniques. One way you can do this is to prepare your code for errors. When an error occurs, you would present a message to the user to make him/her aware of the issue (the error). To prepare a message, you create a section of code in the procedure where the error would occur. To start that section, you create a label. Here is an example: Private Sub cmdCalculate_Click() ThereWasBadCalculation: End Sub After (under) the label, you can specify your message. Most of the time, you formulate the message using a message box. Here is an example: Private Sub cmdCalculate_Click() ThereWasBadCalculation: MsgBox "There was a problem when performing the calculation" End Sub If you simply create a label and its message like this, its section would always execute: Private Sub cmdCalculate_Click() Dim HourlySalary As Double, WeeklyTime As Double Dim WeeklySalary As Double ' One of these two lines could produce an error, such as ' if the user types an invalid number HourlySalary = CDbl(txtHourlySalary) WeeklyTime = CDbl(txtWeeklyTime) ' If there was an error, the flow would jump to the label WeeklySalary = HourlySalary * WeeklyTime txtWeeklySalary = FormatNumber(WeeklySalary) ThereWasBadCalculation: MsgBox "There was a problem when performing the calculation" End Sub To avoid this, you should find a way to interrupt the flow of the program before the label section. One way you can do this is to add a line marked Exit Sub befor
