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
Error Handling Example (VBScript)
<% Dim cnn1 Dim errLoop Dim strError On Error Resume Next ' Intentionally trigger an error. Set cnn1 = Server.CreateObject("ADODB.Connection") cnn1.Open "nothing" If cnn1.Errors.Count > 0 Then ' Enumerate Errors collection and display ' properties of each Error object. For Each errLoop In cnn1.Errors strError = "Error #" & errLoop.Number & "" & _ " " & errLoop.D

This is why I always used Javascript when I could get away with it. –wcm Oct 1 '08 at 14:23 add a comment| 2 Answers 2 active oldest votes up vote 103 down vote accepted VBScript has no notion of throwing or catching exceptions, but the runtime provides a global Err object that contains the reuslts of the last operation performed. You have to explicitly check whether the Err.Number property is non-zero after each operation. On Error Resume Next DoStep1 If Err.Number <> 0 Then WScript.Echo "Error in DoStep1: " & Err.Description Err.Clear End If DoStep2 If Err.Number <> 0 Then WScript.Echo "Error in DoStop2:" & Err.Description Err.Clear End If 'If you no longer want to continue following an error after that block's completed, 'call this. On Error Goto 0 The "On Error Goto [label]" syntax is supported by Visual Basic and Visual Basic for Applications (VBA), but VBScript doesn't support this language feature so you have to use On Error Resume Next as described above. share|improve this answer edited Oct 1 '08 at 14:36 answered Oct 1 '08 at 14:11 Dylan Beattie 33.4k2096154 9 :( ...

В рубрикеПрограммирование на VBSCRIPT В этой статье мы рассмотри обработку ошибок в языке VBScript, а именно объект Err, конструкцию On Error Resume Next и On Error Goto 0. Конструкция VBScript On Error Resume Next включает обработку ошибок, а On Error Goto 0 отменяет их обработку. Объект Err не нуждается в предварительном объявлении, и доступен всегда, давайте рассмотри его методы и свойства: Description - данное свойство содержит описание ошибки. Number - содержит целое число – номер ошибки. Если значение свойства Number ровно нулю – значит, ошибка отсутствует. Source - свойство содержит название приложения, в котором возникла ошибка. Методы Clear – полная очистка информации об ошибке. Стоит обратить внимание, что информация об ошибке автоматически очищается при выполнении операторов On Error Resume Next, Exit Sub и Exit Function. Raise(number, [source, description]) – данный метод позволяет генерировать собственную ошибку времени выполнения. Видим, что тут можно задать параметры, аналогичные по своей принадлежности свойствам самого объекта Err. Видим, что тут является обязательным только первый параметр. Хорошо, теперь давайте рассмотри четыре примера на языке vbscript. Пример 1 '------------------------------------------------------------------------------ ' vbscript on error resume ne
