The ASPError Object

Introduction

The ASPError object is used to display a detailed description about the error that has occurred on the asp page. This object is very useful when you work with asp pages. It calls internally the Server.GetLastError to retrieve the error information. It has several useful properties, which can be used to get detailed information i.e.: the line property can be used to retrieve the line in which the error occurred. Another one is the ASPDescription property, which returns a detailed description of the error. Below you will find a table with all available properties.

NOTE: The ASPError object as well as the GetLastError function can be only called within a 500-error handler page not from any asp page. The best is to create a custom 500-handler page, which includes the required properties. Once you have created your page, you have to change the path for the 500-error handler in IIS. Open IIS and go to the properties of your website. Now press here the Custom Errors tab and scroll down to the 500;100 HTTP Error.

Now press the “Edit Properties” button and change the URL so that it looks for your Custom Error page.

Example of a custom error page (custom500.asp)

<%

            Dim objASPError

            Set objASPError = Server.GetLastError

            Response.Write("ASPCode = " & objASPError.ASPCode)

            Response.Write("ASPDescription = " & objASPError.ASPDescription)

            Response.Write("Category = " & objASPError.Category)

            Response.Write("Column = " & objASPError.Column)

            Response.Write("Description = " & objASPError.Description)

            Response.Write("File = " & objASPError.File)

            Response.Write("Line = " & objASPError.Line)

            Response.Write("Number = " & objASPError.Number)

            Response.Write("Source = " & objASPError.Source)

%>

Example of a simple asp page to generate an error

<%

            dim myvar

            myvar = 1/0
