How can I create my own objects in ASP, like I would in Javascript:

var myObj = new Object();

Thanks.

set var_name = server.createobject("Object")

Server object error 'ASP 0177 : 800401f3'

Server.CreateObject Failed

/asp/test.asp, line 2

I guess my host doesn't support that. Oh well. Thanks.

Invalid ProgID means you tried to create an object that isn't registered

What was the code

Just what you had: set var_name = server.createobject("Object")

Right!

("Object") is simply a placeholder for the parent object you are creating, Simply used here to indicate the syntax. So creating a ADO Database Connection is

Set objConn = Server.CreateObject("ADODB.Connection")

It also depends on which language you are using for ASP. With JScript the syntax is the same as javascript and as the ASP language can be VbScript you also have the similar syntax there for instantiating objects.
Creating a regular expression for example is

Set objRegEx = New RegExp

Ah, see, I'm thinking of creating my own object like you can in JavaScript, here's the JS code:

function run() {
	var myObj = new Object();
	
	myObj.name = "John";
	myObj.age = 21;
	myObj.add = function(x,y) { return x+y };
	myObj.print = function() { document.getElementById("output").innerText = myObj.name + " is " + myObj.age + " years old"};
}

So if I call myObj.print(); it prints "John is 21 years old" and if I call myObj.add(5,3) I get 8... I didn't know if in ASP you could create your own objects on the fly.

I've never used Jscript inside ASP, does that mean I can write in JS and have the server render it instead of the client?

Edit: Wow, for some reason I though JScript ASP was something else... very interesting.

This works:

<% @Language = JScript %>
<%
var myObj = new Object();
        
myObj.name = "John";
myObj.age = 21;
myObj.add = function(x,y) { return x+y };
myObj.print = function() { return myObj.name + " is " + myObj.age + " years old"};

Response.Write(myObj.print());
%>

But does VBScript support user-created objects?

Right, With you now!

Not in ASP as such
To clarify, ASP is NOT a language it is a interpreter system and has two languages that you can use. VBScript and JScript.
ASP with JScript is MS's version of JSP and has the javascript/Java syntax. VBScript (Visual Basic Scripting) is a limited version of VB.
What you are looking for is called classes in VBscript. Basically it is OOP but this is MS territory and of course following suit is not their strong point.

This article from 4Guys Using Classes within VBScript is excellent and covers the subject very well.

And yes, to use JScript with ASP pages is very much like using javascript rendered at the server. There are a few differences to be aware of between client side and server-side obviously.

Got it, that makes it clearer. Thanks.
