Mouse or keyboard input interferes with a section of code that recalculates a workbook opened by the macro (which is importing data from a third source; this workbook takes a while At a basic level, Error Handling involves two parts - (i) enables an error-handling routine with an On Error Statement on encountering an error, and (ii) an error-handling routine which is If you cannot, map the error codes in Err.Number to one of your own errors and then pass them back to the caller of your object. He currently works as a marketing technologist at G.A.

Your answer is an excellent solution for a basic error checking model and many people looking at this will need to go no further. As you are by now already aware how your error handler looks like, Consider this example. This is basically a way to simplify the debugging process by letting you skip the remainder of the current procedure once you realize you don’t need to step into it any The Description Property (Err.Description) returns a short description of the error but this may not exist at times - if no Visual Basic error corresponds to the Number property, the "Application-defined

However, if error handling exists in the procedure, when an error occurs, rather than stopping on the offending line, the code in the Error Handling section is invoked. Sub Sample() Dim i As Integer, j As Integer 10 On Error GoTo Whoa 20 Application.ScreenUpdating = False 30 i = 1111111111 40 For j = 1 To i 50 Debug.Print VB Copy Public Sub OnErrorDemo() On Error GoTo ErrorHandler ' Enable error-handling routine. The Access/VB6 debugger lets you step through each line of code as it runs, examine the environment (including all variables), and even change variable values and lines of code!

Both of these actions generate an error (Type mismatch). But I need more specific info on top-shelf error handling for functions! Customize this to best serve your customers based on their abilities to troubleshoot errors.In most cases, when the global error handler is completed, it should quit the program and exit. This is usually what I want/expect from my error handler...

You can get information on the error from the properties of the Error object - this object is the Err Object. This displays the entire list of local variables and their current values. Each time the error handler passes control back to a calling procedure, that procedure becomes the current procedure. When the debugger encounters an error, one of two things happens: If there's no error-handling routine, the debugger stops at the offending line of code, which can be convenient.

Generally speaking though, it is usually traced to one of two problems. In many cases, if you know the error and the exact line where it occurred, you can immediately understand the problem and fix it. The following modified code uses the IsNumeric function to make sure that Num contains a numeric value. Meaning of S.

VB Copy Sub PopCallStack() ' Comments: Remove a procedure name from the call stack If mintStackPointer <= UBound(mastrCallStack) Then mastrCallStack(mintStackPointer) = "" End If ' Reset pointer to previous element mintStackPointer For example, if you want the program to stop so that you can debug when the variable reaches 500, type the following line of code in the Expression section.
