So if you get a run time error, the response might not be to debug any code, but rather to have the sheet's data fit the code, or the code fit

Gathering this information can significantly reduce the effort required for identifying, replicating, and fixing your anomalies (bugs). The more checking you do before the real work of your application begins, the more stable your application will be. It’s not always the same as the first run because variables may have changed, but if you understand the situation, it lets you debug again without getting to the same code Creating a procedure call stack Unfortunately, while VB6/VBA tracks the procedure call stack and lets you examine it under the View, Call Stack menu item while debugging, this information is not

Your application should make as many checks as possible during initialization to ensure that run time errors do not occur later.

This is why error handlers are usually at the bottom. It is a section of code marked by a line label or a line number.Number PropertyError-handling routines rely on the value in the Number property of the Err object to determine

Here is an example: Private Sub cmdCalculate_Click() ThereWasBadCalculation: End Sub After (under) the label, you can specify your message. Ankit has a strong passion for learning Microsoft Excel. Previously, she was editor in chief for The Cobb Group, the world's largest publisher of technical journals. c.

Next, we calculate the square root of a value. Tip #2 contains the simplest error-handling routine. To get the error description, after inquiring about the error number, you can get the equivalent Description value. The property values in the Err object reflect only the most recent error.

The Future Of Error Handling In VBA Error handling in VB6 and VBA is based on the On Error statement, which leads to awkward code structure.

In many cases, if you know the error and the exact line where it occurred, you can immediately understand the problem and fix it.

Doing so will cause strange problems with the error handlers.

Code such as Stop; Debug.Print; Debug.Assert; should be eliminated or put into sections that won’t be invoked. To reset error handling, use this line: On Error GoTo 0 Or, your standard error handler with an extra clause to handle situations where error handling is not being used: If Technically, these are the only types of errors you can have, but we all know that Access can crash with a GPF. A form may close unexpectedly.

Source Code Libraries FMS also offers source code libraries that eliminate the need to write a lot of code from scratch including code for robust error handling in your applications. The Resume Statement The Resume statement instructs VBA to resume execution at a specified point in the code. Debugging and the Immediate Window The Immediate Window Debugging consists of examining and testing portions of your code or parts of your application to identify problems that may occur when A good article is the one of CPearson.com However I'm still wondering if the way I used to do ErrorHandling was/is completely wrong: Block 1 On Error Goto ErrCatcher If UBound(.sortedDates)

Breakpoints Breakpoints are placed on the lines in your code so the debugger is invoked when the program tries to execute that line. It's habit I can't break :P End Sub A copy/paste of the code above may not work right out of the gate, but should definitely give you the gist.

If you're in the camp that finds error handling during the development phase too invasive, you can add a generic handler and comment it out until you're ready for it. For instance, rather than a simple message that an error occurred, you can specify the exact error number and message: MsgBox "Error: (" & Err.Number & ") " & Err.Description, vbCritical If no error handling is in place, when an Access application crashes, you or your user are prompted with an End, Debug message box: Assuming you’re not running an MDE, when
