VBScript Error Handling
VBScript does not support exceptions, so the DOM and AOM exception classes are not available. All exceptions are mapped to the VBScript
Err global object. The COM error code values listed in
COM Error Handling are available using the
Number property of the
Err object. The message associated with the exception is available using the
Description property. For example:
On Error Resume Next
doc.insertBefore doc, doc ' this is invalid
If Err.Number <> 0 Then
Application.alert("Error: " & Err.Number _
& " Description: " & Err.Description)
Err.Clear
End if
