That's a good idea to check for the references. It is important to set error handling in every procedure else your macro might just crash or stop executing on encountering a run-time error and vba will display a default error Debug.Print Statements The Debug.Print statement lets you write output to the Immediate Window. Tell company that I went to interview but interviewer did not respect start time Exploded Suffixes Physically locating the server Why are so many metros underground?

While this may be acceptable, even desirable, in a development environment, it is not acceptable to the end user in a production environment. UCase("République d'Afrique du Sud") After typing the function and pressing Enter, the result would display in the next line: The Debug Object The Immediate window is recognized in code as These are particularly relevant for managing errors in VBA: VBA global error handle to track and record crashes Microsoft Access database startup routines Conclusions Hopefully, the tips and techniques presented here Advanced Error Handling techniques involve saving information on the error cause and the point of the error, and attempt to resolve the error and provide information to the user on the

Fortunately, both Microsoft Excel and the VBA language provide various tools or means of dealing with errors. For example, On Error Resume Next N = 1 / 0 ' cause an error If Err.Number <> 0 Then N = 1 End If statements. To ignore an error, precede the statement with the Resume Next statement, as follows: On Error Resume Next This statement allows the program to continue to the next line of code,

Sometimes, the right handling means the user never knows the error occurred. Example: Below is a self-explanatory example of ‘On Error Goto

That is, it will be active and ready to handle another error. At the very least, error-handling routines should address the problem, share adequate information on what the user should do next, and exit the program (if absolutely necessary) gracefully. For Error Handling to work properly in VBA, you need a Resume statement to clear the Error Handler. The example code in this article will use the division by zero error (Error 11) when we want to deliberately raise an error.

This is one example of code I use to check if the Microsoft ActiveX Data Objects 2.8 Library is added and if not add or use an earlier version if 2.8 The Resume also reactivates the previous Error Handler.

Without paying attention, after distributing your application, the user's computer may not have an E: drive and, when trying to display the pictures, the application may crash.

Block 1 is, IMHO, bad practice. Debugger for VBA and VB6 There are several parts of the debugger that work together to let you analyze how your code runs: Integrated Development Environment (IDE) Breakpoints Stepping Through and And thanks for the example! This helps you to debug the code.

Well-informed users can change this setting, so I recommend that you include a procedure, similar to the one in Listing A, to your application's startup routine. Analysis During Development Another important use of the debugger is during system development to verify the code is working correctly even if a crash doesn’t occur, or to narrow down the Share Share this post on Digg Del.icio.us Technorati Twitter Reply With Quote « Previous Thread | Next Thread » Like this thread? Your goal should be to prevent unhandled errors from arising.

The more checking you do before the real work of your application begins, the more stable your application will be.

In other words, before writing the On Error GoTo expression, you must have created the label. The On Error Statement The heart of error handling in VBA is the On Error statement.

The Code Cleanup feature standardizes code indentations, adds your error handling to procedures that lack it, adds comment structures, sorts procedures, etc. It is to be noted that an error-handling routine is not a procedure (Sub or Function) but a section of code marked by a line label or a line number.
