maintained. 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 error handling in vbscript tutorial 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.Description & "

В рубрикеПрограммирование на VBSCRIPT В этой статье мы рассмотри обработку ошибок в on error 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 on error resume 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. Вид
