How do you create a custom object in asp like you would in java? I have an asp file which I shall call my class file for an object how to I create an instance of that class file would I be able to do

Dim objectBob

objectBob = Server.createobject("classes\bobclass.asp")

and if that would work what do you call your constructure methods (the same as the page name?) or do they have to be called to initalise the object?

You do not do that in ASP.

If you want to use functions from another file you would use 

that will give you access to all the vars and functions in the file incFile.asp

I think he's talking about COM objects. Saw a great article/tutorial on how to do it, can't actually find it on Google anymore I'm affraid, it's out there somewhere.

Yeah I dont want to use an include because that puts the functions or what ever in the file what I am after is being able to create an object of some file that I have already made so for excample you could have
<%
Dim objCust1
Dim objCust2

set objCust1 = Server.CreateObject("somethingordorder")
set objCust2 = Server.CreateObject("somethingorother")

objCust1.AddToOrder(1234,1)
%>

with includes you can only use it once I bleieve so that AddToOrder call would change both customers but as objects have their own attributes the objCust1.AddToOrder call would only change the attributes for that object and not change the other.

Basically create the DLL in VB or whatever your making it in.

Register it on the server.

Create a new instance of it with the syntax you gave above.

ahh great I though it was something like that but have just worked it out now. Is there any way to test your objects as in making them do every access and update method before you register them? or you you register it make it crash cause its not right change code then update the dll file?

When you save it as a DLL on your computer I think VB automatically registers it. Otherwise you need to type regsv32 obj.dll or something like that on the server.

I found that if the object crashed I kept needing to reset IIS, or ctrl alt delete the dllhost.exe.

You can create script components. You ewill find a tool to make them in Microsoft's scripting tools section or their site. Basically you create an xml file with speciallized object tags and embeded scripts.

Beter yet, go right to the page: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/script56/html/letintro.asp - http://msdn.microsoft.com/library/default.asp?url=/library/en-us/script56/html/letintro.asp

Are you talking about simply using a Class in VBScript?

In which case, just include your class file, and then do

MyObj = New ClassName

Thereafter

ClassName.Method() etc... will work
