Clear Method (Err Object) Visual Studio 2008 Other Versions Visual Studio error trapping in vba 2005 Visual Studio .NET 2003 Clears all property settings of the Err object. Copy object.Clear ParametersobjectAlways the Err object.RemarksUse Clear to explicitly clear the Err object after an error has been handled, such as when you use deferred error handling with On Error Resume Next. The Clear method is called automatically whenever any of the following statements executes: Any type of Resume statementExit Sub, Exit Function, or Exit PropertyAny On Error statementAny Try...Catch...Finally statement Note:The On Error Resume Next construct may be preferable to On Error GoTo when handling errors generated during access to other objects. Checking Err after each interaction with an object removes ambiguity about which object was accessed by the code: You can be sure which object placed the error code in Err.Number, as well as which object originally generated the error (the object specified in Err.Source).ExampleThis example uses the Err object's Clear method to reset the numeric properties of the Err object to zero and its string properties to zero-length strings.

On Error GoTo -1 clears the error handling and sets it to nothing which allows you to create another error trap. Example: On Error GoTo -1 After the first error is raised, it will GoTo ErrorFound which will then clear the routine's error handling and set a new one, which will GoTo AnotherErrorFound when an error is found. Sub OnErrorGotoMinusOneTest() On Error GoTo ErrorFound Err.Raise Number:=9999, Description:="Forced Error" Exit Sub ErrorFound: On Error GoTo -1 'Clear the current error handling On Error GoTo AnotherErrorFound 'Set a new one Err.Raise Number:=10000, Description:="Another Forced Error" AnotherErrorFound: 'Code here End Sub Example: On Error GoTo 0 After the first error is raised, you will receive the error as error handling has been disabled.

It is interesting to point out that ONLY On Error Goto -1 will allow
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 http://www.cpearson.com/excel/errorhandling.htm cannot correctly execute a program statement. We will concern ourselves here only with run time http://www.globaliconnect.com/excel/index.php?option=com_content&view=article&id=348:excel-vba-errors-error-handling-on-error-resume-satements-exit-statement-err-object&catid=79&Itemid=475 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) 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 on error 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 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 on error goto 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. 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

On encountering a run-time error, an On Error statement enables or disables an error-handling routine within a procedure. A Resume statement can only be used in an error-handling routine - it resumes execution at a sepcified point after the error-handline routine finishes. You can get information on the error from the properties of the Error object - this object is the Err Object. In this section, we cover: VBA Erros & Error Handling In vba programming you can have Syntax Errors or Run-time Errors. An error handler determines what action is to be taken within a procedure, on the occurrence of a run-time error. A syntax error occurs when you enter a line of code which is not allowed or recognized by Visual Basic. You will encounter a syntax error on misspelling a keyword or a named argument, for incorrect punctuation (ex. not specifying a comma as a placeholder for the omitted argument), use an undefined procedure, and so on. These errors are easier to locate as the Code Editor points them out at the time you are writing your code. A run-time error occurs at the time during which your code is running, that is after you have created your macro. There could be an error in your programming due to incorrect logic used in your code that prevents it from doing what you intended and may stop code execution, for example, if your code attempts to divide a value by zero. Another reason for an error which may cause even a valid code to crash could be a condition not being met, say, a reference to a worksheet in your code which has been deleted by the user. Other examples when a run-time error can occur are: on using incorrect variable names or variable types; if your code goes into an infinite loop; using a value or reference outside the allowable range; and so on.
