Raise Method (Err Object) Visual Studio 2008 Other Versions Visual Studio 2005 Visual Studio .NET 2003 Generates a run-time error; can be used instead of the Error statement. Copy Public Sub Raise( _ ByVal Number As err.raise vbscript Integer, _ Optional ByVal Source As Object = Nothing, _ Optional ByVal Description As Object = Nothing, _ Optional ByVal HelpFile As Object = Nothing, _ Optional ByVal HelpContext As Object = Nothing _ ) ParametersNumberRequired. Long integer that identifies the error. Visual Basic errors are in the range 0–65535; the range 0–512 is reserved for system errors; the range 513–65535 is available for user-defined errors as well. However, when you set the Number property for an error that you are creating, add your error code number to the vbObjectError constant. For example, to generate the error number 1000, assign vbObjectError + 1000 to the Number property.SourceOptional. String expression naming the object or application that generated the error. When setting this property for an object, use the form project.class. If Source is not specified, the process ID of the current Visual Basic project is used.DescriptionOptional. String expression describing the error. If unspecified, the value in the Number property is examined. If it can be mapped to a Visual Basic run-time error code, the string that would be returned by the Error function is used as the Description property. If there is no Visual Basic error corresponding to the Number property, the "Application-defined or object-defined error" message is used.HelpFileOptional

October 22, 2015 AnalystCave Leave a comment Writing VBA code is hard, vba error but properly debugging code is even harder. Sounds like non-sense? Well I dare say developers spend more time debugging code than writing it. Looking for errors is what developers do most of the time! A critical part of debugging is proper error handling (VBA error handling in our case). Debugging is twice as hard as writing the code in the first place. raise error vba Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it. — Brian W. Kernighan However, today I don't want to expand on debugging VBA. That I covered in this post. No - today let's learn how to properly handle errors The Mouse Trap Analogy What is error handling? Take this analogy: Say you have a mouse (an error) in the house which turns up every now and then in the least expected moment as slips from your hands (an uncaught exception if you prefer). Without knowing where the mouse is and when it (the exception/error) will appear (in which line of code) you would need to search entire house to catch it (run through the entire code in our case). Obviously a better approach is setting mouse traps in several critical places in the house (corridors etc.) and waiting for the mouse to fall into your trap. So what is our mouse trap when speaking about VBA error handling? The On Error do this statement! Using VBA On Error The VBA On Error s

Syntax errors Syntax errors, also called parsing errors, occur at interpretation time for VBScript. 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: 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 tha
