For example, the following line causes a syntax error because it is missing a closing parenthesis: Function ErrorHanlding_Demo() dim x,y x = "Tutorialspoint" y = Ucase(x End Function Runtime errors Runtime errors, also called exceptions, occur during execution, after interpretation. For example, the following line causes a runtime error because here syntax is correct but at runtime it is trying to call fnmultiply, which is a non-existing function: https://www.tutorialspoint.com/vba/vba_error_handling.htm Function ErrorHanlding_Demo1() Dim x,y x = 10 y = 20 z = fnadd(x,y) a = fnmultiply(x,y) End Function Function fnadd(x,y) fnadd = x+y End Function Logical errors Logic errors can be the most difficult type of errors to track down. These errors are not the result of a syntax or runtime error. Instead, they occur when you make a mistake in the logic that drives your script and you do not get the result you expected. You can not catch those errors, because it depends on your business requirement what type of logic you want to put in your program. For example, dividing a number by zero or a script that is written which enters into infinite loop. Err Object Assume if we have a runtime error, then the execution stops by displaying the error message. As a developer, if we want to capture the error, then Error Object is used. Example In the below example, Err.Number gives the error number and Err.Description gives error description. Err.Raise 6 ' Raise an overflow error. MsgBox "Error # " & CStr(Err.Number) & " " & Err.Description Err.Clear ' Clear the error. Error Handling VBA Enables an error-handling routine and can also be used to disable an error-handling routine. Without an On Error statement, any run-time error that occurs is fatal: an error message is displayed, and execution stops abruptly. On Error { GoTo [ line | 0 | -1 ] | Resume Next } KeywordD
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 http://www.exceltrick.com/formulas_macros/vba-on-error-statement/ 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 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 gracefully. Definition of VBA On Error Statement: On Error error handling statement instructs VBA Compiler, what to do in case any runtime 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
