The way you access the ASPError Properties is with a Server Method. Yeah, I know; it doesn't make sense. Start with something like var myError=Server.GetLastError() and then you can access all nine ASPError Properties following this pattern: %=myError.Line%>.

Below is the script for Lesson 15.

%@LANGUAGE="JavaScript"%>
!-- METADATA TYPE="typelib" 
FILE="C:\Program Files\Common Files\System\ado\msado15.dll" -->

try
	{
	Response.Write("STRONG>Use I>GetLastError( )/I>BR>/STRONG>\r")
	myError = Server.GetLastError()
	Response.Write("myError.Line: " + myError.Line + "BR>\r")
	Response.Write("myError.File: " + myError.File + "\r")
	Response.Write("HR>\rSTRONG>")
	Response.Write("Now an intentional error...")
	Response.Write("BR>/STRONG>\r")
	myError = erver.GetLastError() //this line causes an error
	Response.Write("myError.Line: " + myError.Line + "BR>\r")
	Response.Write("myError.File: " + myError.File + "BR>\r")
	}
catch(myDumbError) 
	{ 
	Response.Write("There is an error: " + myDumbError)
	%>
	BR>
	Graceful error handling goes here (inside the catch statement).

	%
	for ( var i in myDumbError)
		{
		Response.Write(i + ": " + myDumbError[i] + "BR>\r")
		}
	}
finally
	{
	Response.Write("HR>STRONG>Let's Finish Up./STRONG>BR>\r")
	Response.Write("Code inside the I>finally { }/I> statement ")
	Response.Write("executes regardless of error (or lack thereof). \r")
	Response.Write("I>finally{ }/I> is totally optional. ")
	Response.Write("It's a good place for things like RS.Close()... ")
	Response.Write("which you'll see later on.")
	}
%>

Okay, so what happened to On Error Resume Next? Sorry, that ain't no JavaScript thing. So, what about onerror? That won't work on the server side. But thanks to some core JavaScript we have some error handling.

The section of script for which you wish to provide error handling goes inside the try { } statements and the what-to-do in the event of an error goes inside the catch { } statement. There is also a finally { } statement (optional). The whole thing is just as graceful as On Error (in my opinion).

Not every ASP server allows you access to the ASPError Object. So, don't be surprised if ASPError gives you an error.
