code ... ... some code that must always be run (like a finally block) ... I want to handle both errors, and resume execution after the code where the error may occur. Also, the finally code at the end must ALWAYS run - no matter what exceptions are thrown earlier.

Errors in the error handling routine are terminating. The range 513-65535 is available for user errors. For custom class errors, you add vbObjectError to the error number. For not implemented interface members in a derived class, you should use the constant E_NOTIMPL = &H80004001

October 22, 2015 AnalystCave Leave a comment Writing VBA code is hard, but properly debugging code is http://stackoverflow.com/questions/1038006/good-patterns-for-vba-error-handling 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. Therefore, if you write the code as cleverly http://analystcave.com/vba-proper-vba-error-handling/ as possible, you are, by definition, not smart enough to debug it. โ€” 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 statement - tells VBA what it should do from now on, within the vicinity of th

tutorial examples and notes on runtime error handling. Topics include the default error handling behavior; 'On Error Resume Next' and 'On Error GoTo 0' statements; catching errors with (Err.Number > 0); clear Err object with Err.Clear(); raise your own errors with Err.Raise(...). In previous sections, we learned that the "Err" is used the host environment to raise pre-defined runtime errors. VBScript also allows you to use the "Err" to raise your own runtime error with the Err.Raise() method: Call Err.Raise(number, source, description) where: "number" is an integer in the range of 0 and 65535 to represent a specific error condition. But lower values are already used by VBScript for predefined errors. So you should use higher values, like 60000, 60000, ... "source" is a string to identify where the error occurred. "description" is a string to describe the error condition. To show you how the Err.Raise() method works, I wrote the following VBScript example,
