Vba Error Handling Best Practices
generation our VBA code will supercede the use of certain wizards. One of those will eventually be the VBA Code Wizard. Although it is a quick method of generating a procedural ‘shell’, it’s auto-generated error handling can be more robust when we more effectively manage any errors that may occur. Writing error handling routines for each and every procedure can be tedious. The code example(s) and demo ms access on error resume next app of this tutorial can provide a way to trap and manage unexpected errors. But then, what other kind of error is there? (Random, undocumented features, to be sure!) A ‘global’ approach to error handling is the thrust of this discussion, where we will employ ‘global’ variables to assist in the management of the information collected during an error trapping process. We will also explore the primary Error Handling routine(s)/module in detail and how the ‘global’ variables play their part in passing a procedure’s error info to the primary routine. Then, once the primary routine has been given a procedural call and error info, we will be able to present a user with an on-screen message, a text-based error file and/or the ability to email the error to a developer and/or application administrator. Also demonstrated will be how to bring these Global Error Handling routines into your working Access application.

The primary module, modErrorHandler, contains both the global variable declarations as well as the primary error handling engine. Normally, I keep all global vari

In the Open_Workbook routine I set On Error Goto ErrorHandler: Then within that same routine I create a basic ErrorHandler to display a message box and then close the workbook. The problem I have is that the ErrorHandler doesn't seem to fire for any of the errors that get reported by Excel....I still get the http://www.vbaexpress.com/forum/showthread.php?26715-Global-Error-Handling default Error Message box giving the user the option to Debug, End or Continue.. I had thought from my reading that once you set an On Error statement that it stays inforce until you set an On Error Goto 0....but it doesn't seem to working like that for me... Any help appreciated..

I have probably over 100 Procedures in this workbook....is there a way to have a Global Error Handler setup ?

Surprisingly though, errors and their properties are relatively unknown to a large part of the development community. To effectively implement error handling in your applications, it is necessary to know the resources that are available when your program encounters an error. Assuming we are working with non-executable programs (.mdb's or .accdb's), the most important thing to understand is the global settings for error trapping in our VBA procedure. Under the "Tools » Options" menu, then on the "General" Tab there are three options for error trapping: Break on all errors » Stops code execution when an error is encountered. Break in class module » Stops code execution in class modules only. Break on unhandled errors » Stops code execution only if there is no error handling routine present in the procedure. This is the global setting for error handling. So, if error traps are present in our procedures, they will be ignored if we have specified the "Break on all errors" option. In the following image, we've done just that: There are three important statements in an error handling routine: On Error, Resume and GoTo. Typically, they will appear together at the beginning of a procedure: On Error Resume Next On Error GoTo 0 The "Resume" and "GoTo" statements simply tell VBA what to do when an error is encountered. First, Resume has two primary actions associated with it: Resume Next » Ignores the encountered error and continues execution with the next line of code. Resume (label) » After an error occurs, code execution resumes on the first line of code after the labeled line. Similarly, GoTo is usually found in two forms: GoTo 0 » Terminates the procedure's error handler. In other words, this statement disables it. GoTo (label) » Identical to the Resume statement. Execution jumps to the first line after the labeled line. So which is best to use? It
