What does the “On Error Resume Next” statement do?

Question

I came to some VBScript examples, and I saw the statement On Error Resume Next basically at the beginning of the script.

What does it do?

Answer 1

It's worth noting that even when On Error Resume Next is in effect, the Err object is still populated when an error occurs, so you can still do C-style error handling.

If Err Then
    WScript.StdErr.WriteLine "error " & Err.Number
    WScript.Quit 1
End If
