You should specify your error by adding your error code to the VbObjectError constant. It does not specify line -1 as the start of the error-handling code, even if the procedure contains a line numbered -1. It's ugly. Vba Error Handling Best Practices When there is an error-handling routine, the debugger executes it, which can make debugging more difficult.

Just ask if that applies to your use of this code. have a peek here So just before the ErrHandler: label, I've used an Exit Sub statement.
Note that Err.Clear is used to clear the Err object's properties after the error is handled. Use this form rather than On Error GoTo when accessing objects.Remarks Note We recommend that you use structured exception handling in your code whenever possible, rather than using unstructured exception handling and For example, On Error Resume Next N = 1 / 0 ' cause an error If Err.Number <> 0 Then N = 1 End If Why would you not accept a free great person?
This one is six years old and probably has few of the posters still available. It instructs to VBA to essentially ignore the error and resume execution on the next line of code.
