Are Vbscript Classes Fast?

Say I have a few functions for accessing a database e.g. openDBConn, closeDBConn, openRs, closeRs, getRsAsArray, executeSql, getDbConnString etc

I could put these functions in to an include file "incDbHelper.asp" and include the file in any page that needs database functionality... or I could create a class "clsDbhelper.asp" which again I would include in any page that needs it. Now once the files have been included, to access the functions I could do: Code:

Vbscript Classes & A Recordset (ASP)

I've written two classes in ASP (vbscript). Basically I am attempting a form of data encapsulation. The classes are a "master" class and an "address" class. The address class basically wraps a recordset. I've attached the file. whenever I call the "move" method the recordset should be EOF since there is only 1 record in my streetaddress table. If I write out the value of of p_oRs.eof inside of the "move" method it returns true.

I have declared p_oRs as a public variable. But if I access it from a different method (or a property get/let) then the p_oRs recordset is no longer EOF the pointer is on the first and only record.

ASP Classes

I've been searching for some information on the use of Classes in ASP, but

Classes Vs COM

For the majority of my work, I just use plain ASP. On the rare occasion that
I am doing something intensive that does require user interaction I might
create a COM component (ie where performance gain outweighs the overhead of
COM).

A simple Rule-of-Thumb. I imagine this is fairly common practice... (I hope
it is, at least).

However, I'm curious about VBScript Classes. I would have imagined that if a
page was complex enough to merit defining and creating your own
classes/objects, that COM would be appropriate...

In which case, when and how do people use VBScript Classes?

VB Classes

I am re-coding a VB application to be used on the web, some of which requires additional DB components for user registration etc. Usually I use ASP classes to manage the DB I/O stuff but I was wondering whether they are any benefits in having them as VB classes and compiled as dlls?

I like the idea of having the VB application as dlls, but using asp classes for the general functionality of the application. However, I don't wish to do this out of convience for myself.

Classes

one developer once told me that he doesn't use classes as there is a performance issue. is this true? the functions i'd be creating can easily go into an include file as a set of functions and not a class. so i'm not too sure about going ahead and encapsulating them into classes. has anyone got any input?

Classic ASP Classes

I've been working in .NET for some time now and I don't remember specifically
how asp classes are cleaned up in classic asp. I've been put on a Classic
ASP project(ugh) and we're having some serious stability problems. Once we
reach a point of sustained CPU useage of over 80% IIS 6 restarts the w3wp.exe
process which of course terminates all sessions and resets the website.

I've
noticed that the previous developer has an include which creates a couple of
class objects in ASP. Not third party or "CreateObject" objects, but ASP
classes. This include is in A LOT of files and the classes not being
destroyed in any of them.

My question is could this be the problem? I seem to remember a problem with
ASP classes and not destroying them causing leaks of some sort. I need to
mention that the memory doesn't seem to be leaking but the CPU utilization
goes wacko as if ASP/IIS is corrupt. My environment is Windows 2k3 and IIS
6. The previous environment was Windows 2K and IIS5. Both environments had
the problem.

Before I go through these hundreds of files I was wondering if anyone
remember what the problem was with ASP classes not being destroyed.

Classes And Collections In ASP?

Classes With Databases

I'd like to create a class file for a shopping cart that I'm working on but I'm not sure about how to use the database with it.

Do I connect and open to the database inside the class or outside of the class and set the properties?

I'm thinking that if I open and close the database with say a getItem() method and I have 15 items to get, I'll be opening and closing a connection 15 times. Isn't that bad?

Using .NET Classes In An ASP Classic App?

Is there a way to use classes written in .NET in an ASP classic application? Maybe similair to using DLLs with Server.CreateObject? I want to write all our new classes using .NET with the intent of eventually changing the web application to ASP.NET.

I've tried Googling for the answer but I only get ASP.NET literature. Any suggestions for that problem?

Validation Inside Classes

I'm currently new to OO programming with Classic ASP and have been stopped dead in my tracks on the issue of validation inside classes and if I should be doing things that way. I have been using a User class and it has methods such as Save(), Update() and Delete(). Particularly with the Update() method I'm unsure if I should be validating my form(s) within the class or on the actual edit.asp page that uses the Update() method?

I have two types of edit pages; one for Admin users and one for the My Account page. On the My Account page if the user wants to change their password they have to enter their current password, a new password and then their new password again to confirm .

If an Admin user is updating that same user's info they do not have to go through those steps and they can simple just change the password by typing it in. The point here is that there are two separate cases of validation rules on two separate pages that both use the Update() method. Do you validate your forms inside your classes or outside?

Pass Array Of Classes

I'm trying to pass an array of classes through a function using vbscript and then access these the other side. for instance (in psuedo code)

redim Array()
for 0 to array end fill with data (these happen to be classes)
but not sure that should make any difference?!)

someFunction(array())

function someFunction(data)
response.write data(0).property
end function

which doesn't work although data.property does if I specify which part of the array I'm passing i.e. someFunction(array(1))

User-defined Classes In Global.asa

I've read that one shouldn't include ADO objects in the Global.asa for the sake of performance, but would user-defined classes cause the same kind of performance hit? Assuming that they wouldn't, is it possible to do it?

Is there a way to do this? Or should I create a slew of Session variables? Code:

Using VBscript In Asp.net?

I tried using some code examples from (URL address blocked: See forum rules) into my defualt.aspx page (in VS2005). I had some errors with this. I thought this might be cause the tutorial at w3schools.com said it was for *.asp files.

For example I had an error ("Statement cannot appear within a method body. End of method assumed) when I tried putting a SUB in the <head>. Like this

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "(URL address blocked: See forum rules)">

<html xmlns="(URL address blocked: See forum rules)" >
<head runat="server">

<%
sub vbproc(num1,num2)
response.write(num1*num2)
end sub
%>

<title>Untitled Page</title>
</head>


By the way if anybody will be available to answer basic questions like this every so often throughout the day (ie: check your email or this forum every couple of hours, until midnight California time December 8), I'd be willing to pay a reasonable amount. I just need help with some of the technical details like this + finding source code

ASP VBscript

I'm trying to create a simple recordset, and would like to include an and/or option. to do this i set up an option on the previous page,and then sent the selection through to the next page. i was then hoping to simply insert the variable i had created into the code so that whichever of and/or is selected is used in the code. i.e.

where and_or is the variable from the previous page.

Search.Source = "SELECT * FROM dbo.Employee_List where First_Name='"&firstname&"' '"and_or"' Last_Name='" &lastname&"'"

so basically whenever someoned chooses an option its automatically filled in at the indicated location in the code. is it possible to do this and if so what is the correct syntax for using variables within this code?the full search function will have numerous fields so i'd like to avoid using if statements.

Like I said...I have no knowledge or experience with this. From what I read, there are two ways of coding ASP. First using VBScript and then C#. I'm really confused, because for one, I don't know what the difference is, and secondly I'm ot sure which is the best.

I'll be primarily (if not only) be using ASP to build online applications, websites, etc.

a dictionary of terms with definitions, (in a database) how can i hyperlink(automatically) words within the definitions for which a definition also exists.

url structure is like this

www.site.com/glossary?word=someword

Then - in the definition of "someword" there is a word that also has a definition in the database. I'd like to auto hyperlink it to that definition. Also since the data is all coming from a database, what if one of the words to be replaced has not yet come up in the loop? (...or would it be okay since EVERYTHING should be in the recordset?
