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 cannot correctly execute a program on error exit sub statement. We will concern ourselves here only with run time errors. Typical run time errors include vba on error goto 0 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 vba error handling in loop 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 https://msdn.microsoft.com/en-us/library/5hsw66as.aspx 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 a run time error occurs, VBA will display its standard run time error dialog box. While http://www.cpearson.com/excel/errorhandling.htm 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
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 http://www.exceltrick.com/formulas_macros/vba-on-error-statement/ 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 https://wiki.openoffice.org/wiki/Documentation/BASIC_Guide/Error_Handling 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 on error 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

OpenOffice.org Basic provides a range of tools for simplifying error handling. The On Error Instruction The On Error instruction is the key to any error handling: Sub Test On Error Goto ErrorHandler ' ... undertake task during which an error may occur Exit Sub ErrorHandler: ' ... individual code for error handling End Sub The On Error Goto ErrorHandler line defines how OpenOffice.org Basic proceeds in the event of an error. The Goto ErrorHandler ensures that OpenOffice.org Basic exits the current program line and then executes the ErrorHandler: code. The Resume Command The Resume Next command continues the program from the line that follows where the error occurred in the program after the code in the error handler has been executed: ErrorHandler: ' ... individual code for error handling Resume Next Use the Resume Proceed command to specify a jump point for c
