a run-time error; can be used instead of the Error statement. Copy Public Sub Raise( _ ByVal Number As 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-

Excel, MS Office, Outlook, PowerPoint, Word Proper VBA error handling (3 votes, average: 4.67 out of 5) Loading... October 22, 2015 AnalystCave Leave vba user defined error a comment Writing VBA code is hard, 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 https://msdn.microsoft.com/en-us/library/w4t2e92e(v=vs.90).aspx 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. 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 http://analystcave.com/vba-proper-vba-error-handling/ 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 statement - tells VBA what it should do from now on, within the vicinity of the current block of code (Function or Sub), when an error/exception is raised. It is like setting a mouse trap - with the difference that you can tell it to drop the mouse off the dumpster or put it in your hands to manage. Let's remind the full syntax of the On Error statement in VBA first: On Error { GoTo [ line | 0 ] | Resume Next } Directly from MSDN we learn the different VBA error handling opti

does not support the new Try/Catch blocks found in VB.net or any other modern programming languages. To handle errors within a procedure the "On Error Goto" statement must be used. When used, VBA expects the procedure to handle the error by either displaying a message visible to the user or just ignore it and continue as before. However, if you are a Java or .NET developer you might want to restore the state of the application when a error is caught and then re-throw the error to let another part of the application handle it, just like when the "using" statement or throw/catchblocks are applied in C# code. There is no direct way of re-throwing a error in VBA, like throw or throw [Exception] in Java and .NET. The correct way of solving this challenge is to use the Err.Raise method, and specify all the existing error parameters in the following way: Sub Test() On Error GoTo ErrorHandler ' Do Something Exit Sub ErrorHandler: ' Restore state ' Re-throw/Raise existing error Err.Raise Err.Number, Err.Source, Err.Description, Err.HelpFile, Err.HelpContext End Sub A custom method can be made to simplifying the re-throwing of errors: ' Rethrow Public Sub ReThrowError(ByVal objError As ErrObject) ' Raise Err.Raise objError.Number, objError.Source, objError.Description, objError.HelpFile, objError.HelpContext End Sub Lagt inn av Ulf kl. 6:04 PM error, excel, exception, microsoft, programming Olá!
