") response.write(Err.description) response.write("
") response.write(query) response.write("
") end if on error goto 0 rs.movenext loop the question is : during a loop, if it encounters an error, the next cycle will the error be there (and so triggers again the error block) ? or on error goto 0 will clear the Err object? in other words, will it works as a error handling? asp-classic vbscript error-handling share|improve this question edited Jul 3 '13 at 10:51 Alex K. 107k16149195 asked Jul 3 '13 at 10:43 Matteo Bononi 'peorthyr' 77151749 add a comment| 3 Answers 3 active oldest votes up vote 5 down vote accepted VBScript resets the error on goto 0: on error resume next i = 1 / 0 WScript.echo( err.number ) '' prints 11 (div by 0) on error goto 0 WScript.echo( err.number ) '' prints 0 (no error) There is also the explicit err.clear(). share|improve this answer answered

This documentation is archived and is not being maintained. Handling Errors in VBScript There is little difference between the methods used in Visual Basic and those used with VBScript. The primary difference is that VBScript does not support the concept of error handling by continuing execution at a label. In other words, you cannot use On Error GoTo in VBScript. Instead, use On Error Resume Next and then check both Err.Number and the Count property of the Errors collection, as shown in the following example: Copy

However, you can trap for errors, suppress errors, and stop suppressing errors. When an error is found, you can also handle it. Suppressing Errors To start trapping errors, add the following line:On Error Resume Next This will suppress all errors for the duration of the script. For example, normally the following code would cause the death of your code with a division by error message:Dim xx = 1/0 However, you can suppress the error as follows:On Error Resume NextDim xx = 1/0 The above code will cause NO error at all.
