It doesn't specify line 0 as the start of the error-handling code, even if the procedure contains a line numbered 0. To enable this, use the Err object's Raise method.   The arguments of the Raise Method correspond to the properties of the Err object, and all arguments except the Number argument not specifying a comma as a placeholder for the omitted argument), use an undefined procedure, and so on. Private Const ThisModuleName As String = "mod_Custom_Functions" Public sLocalErrorMsg As String Within each Sub/Function of the module I define a local variable Dim ThisRoutineName As String I set ThisRoutineName to the

An error handler is automatically disabled when a procedure is exited or if it has has run completely, if the procedure does not have an On Error GoTo 0 statement.  

Without using the 'On Error Resume Next' statement you would get two errors. The property settings of the Err object relate to the most recent run-time error, so it is important that your error-handling routine saves these values before the occurrence of another error. Every error handler must be ended by exiting the procedure or a Resume statement.

What is that the specific meaning of "Everyone, but everyone, will be there."? Err.Clear is used to clear the properties of the Err object properties after the error is handled - using the On Error Resume Next statement defers error handling, whereas an error-handling A compile-time error will occur if the specified line argument is not in the same procedure as as the On Error statement. Instead of letting the program crash, we can provide a number as an alternative.

Anytime you use Resume Next, you need to reset error handling by using the following statement: On Error GoTo 0 GoTo 0 disables enabled error handling in the current procedure and That's a good idea to check for the references.

The Error Number As mentioned already, there are various types of errors that can occur to your program. This has been explained & illustrated in Example 4 above.   Arguments of Raise Method: The Number argument is the error's number. 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.

When you're ready to enable error handling, simply reset the constant to True. This resulted in an error. You can not catch those errors, because it depends on your business requirement what type of logic you want to put in your program.

Run-Time Errors A run-time error occurs when your application tries to do something that the operating system does not allow. If you do not regenerate the error in the called procedure whose enabled error handler is incapable of handling the error, the error may cause the macro to stop or continue That's the easy part, but you're not done.
