See this Example. You can trap the Error Number using Err.Number Sub Sample() On Error GoTo Whoa '~~> Rest of the code Exit Sub Whoa: Select Case Err.Number Case 9 vba error message dialog box MsgBox "Message1" Case 1004 MsgBox "Message2" End Select End Sub FOLLOWUP Sub Sample1() On Error GoTo Whoa '~~> Rest of the code Exit Sub Whoa: MsgBox GetErrMsg(Err.Number) End Sub Sub Sample2() On Error GoTo Whoa '~~> Rest of the code Exit Sub Whoa: MsgBox GetErrMsg(Err.Number) End Sub Function GetErrMsg(ErNo As Long) As String Select Case ErNo Case 9 GetErrMsg = "Message1" Case 1004 GetErrMsg = "Message2" Case Else GetErrMsg = "Message3" End Select End Function share|improve this answer edited Jul 16 '12 at 15:18 answered Jul 16 '12 at 14:25 Siddharth Rout 91.1k11102146 Sweet and simple, the best type of code, thanks :) Just one question, does this have to go into each section, or can this be created as it's own module? –Matt Ridge Jul 16 '12 at 14:47 It has to go into each section. But you can write a common procedure on what you want to do for example... see the updated code... –Siddharth Rout Jul 16 '12 at 15:17 Thanks again, exactly what I needed :) –Matt Ridge Jul 16 '12 at 16:01 I just tried this, and I'm getting a "Label Not Defined" message. –Matt Ridge Jul 16 '12 at 17:30 Please show us your code. –Siddharth Rout Jul 16 '12 at 17:31 | show 3 more comments Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Pass

In particular, what should I do in this situation: ... some code ... ... some code where an error might occur ... ... some code ... ... some other code where a different error might occur ... ... some other code ... ... some code that must always be run (like a finally block) http://stackoverflow.com/questions/1038006/good-patterns-for-vba-error-handling ... 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 4 Comments Writing VBA code is hard, but properly debugging code http://www.functionx.com/vbaexcel/Lesson26.htm 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 error message 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. 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) vba error message 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 options we have with the On Error statement: On Error Goto - or On Error GoTo [ lineLabel | 0 | -1 ] if preffered. The Goto instruction in VBA let's you do a jump to a specific VBA code
the wrong time. The application may crash. A calculation may produce unexpected results, etc. You can predict some of these effects and take appropriate actions. Some other problems are not under your control. Fortunately, both Microsoft Excel and the VBA language provide various tools or means of dealing with errors. Practical Learning:Introducing Error Handling Open the Georgetown Dry Cleaning Services1 spreadsheet and click the Employees tab Click the Payroll tab Click the TimeSheet tab To save the workbook and prepare it for code, press F12 Specify the folder as (My) Documents In the Save As Type combo box, select Excel Macro-Enabled Workbook Click Save Introduction to Handling Errors To deal with errors in your code, the Visual Basic language provides various techniques. One way you can do this is to prepare your code for errors. When an error occurs, you would present a message to the user to make him/her aware of the issue (the error). To prepare a message, you create a section of code in the procedure where the error would occur. To start that section, you create a label. Here is an example: Private Sub cmdCalculate_Click() ThereWasBadCalculation: End Sub After (under) the label, you can specify your message. Most of the time, you formulate the message using a message box. Here is an example: Private Sub cmdCalculate_Click() ThereWasBadCalculation: MsgBox "There was a problem when performing the calculation" End Sub If you simply create a label and its message like this, its section would always execute: Private Sub cmdCalculate_Click() Dim HourlySalary As Double, WeeklyTime As Double Dim WeeklySalary As Double ' One of these two lines could produce an error, such as ' if the user types an invalid number HourlySalary = CDbl(txtHourlySalary) WeeklyTime = CDbl(txtWeeklyTime) ' If there was an error, the flow would jump to the label WeeklySalary = HourlySalary * WeeklyTime txtWeeklySalary = FormatNumber(WeeklySalary) ThereWasBadCalculation: MsgBox "There was a problem when performing the calculation" End Sub To avoid this, you should find a way to interrupt the flow of the program before the label section. One way you can do this is to add a line marked Exit Sub before the label. This would be done as follows: Private Sub cmdCalculate_Click() Dim HourlySalary As Double, WeeklyTime As Double Dim WeeklySala
