On Error Statement

Microsoft® Visual Basic® Scripting Edition
On Error Statement

Description

Enables error-handling.

Syntax

On Error Resume Next

Remarks

If you don't use an On Error Resume Next statement, any run-time error that occurs is fatal; that is, an error message is displayed and execution stops.
On Error Resume Next causes execution to continue with the statement immediately following the statement that caused the run-time error, or with the statement immediately following the most recent call out of the procedure containing the On Error Resume Next statement. This allows execution to continue despite a run-time error. You can then build the error-handling routine inline within the procedure. An On Error Resume Next statement becomes inactive when another procedure is called, so you should execute an On Error Resume Next statement in each called routine if you want inline error handling within that routine.
The following example illustrates use of the On Error Resume Next statement:
On Error Resume Next
Err.Raise 6  'Raise an overflow error.
MsgBox ("Error # " & CStr(Err.Number) & " " & Err.Description)
Err.Clear    ' Clear the error.
