On Error Statement  Enables or disables error-handling.Syntax Copy On Error Resume Next On Error GoTo 0 RemarksIf you don't use an On Error Resume Next statement anywhere in your code, any run-time error that occurs can cause an error message to be displayed and code execution stopped. However, the host running the code determines the exact behavior. The host can sometimes opt to handle such errors differently. In some cases, the script debugger may be invoked at the point of the error. In still other cases, there may be no apparent indication that any error occurred because the host does not need to notify the user. Again, this is purely a function of how the host handles any errors that occur.Within any particular procedure, an error is not necessarily fatal as long as error-handling is enabled somewhere al

Be very cautious using it. –Nate Feb 4 '10 at 20:22 2 It makes more sense now. After some functions that can end up in error. They have a function called checkError after them. –Omar Feb 4 '10 at 20:37 add a comment| 6 Answers 6 active oldest votes up vote 56 down vote accepted It basically tells the program when you encounter an error just continue at the next line. share|improve this answer answered Feb 4 '10 at 20:19 David 2,2601523 add a comment| up vote 24 down vote 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.

provides a tutorial example on how to use the 'On Error Resume Next' statement to turn on error handling flag. You can use Err.Number > 0 to test if there is any runtime error has been raised or not. We have seen what happens when the error handling flag is turned off in the previous section. Now let's see how the "On Error Resume Next" statement should be used: By default, the error handling flag is turned off. You can turn on the error handling flag at time your want by entering the "On Error Resume Next" statement. Once the error handling flag is turned on, execution will not be stopped when a runtime error occurs. You can use the condition of (Err.Number>0) to determine a runtime error has occurred or not.

Err.Description - "Err" object property containing the error description. Err.Source - "Err" object property containing error source identification. I have modified the VBScript example used in the previous section to try to check the "Err" object by myself with the error handling flag turned on:
