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?
I have an ASP application which gathers information to put in a database via some forms - I would like to do the form validation (making sure some fields are not empty) with a Javascript script inside the ASP file - what is the syntax for doing this? Usually I would place the javascript inside the <head> tags, but ASP files don't have those.
I've been searching for some information on the use of Classes in ASP, but found very little information. I found this http://www.daniweb.com/tutorials/tutorial19997.html . Are there more information somewhere online?
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?
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.
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?
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.
I've always had problems getting my head around using collections and classes together. Separately, they seem like fairly simple subjects, but I'm getting muddled up when trying to use them together.
Can someone toss together a simple example of how I'd create my classes and collection? Code:
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?
I write classes in php, beans in jsp, what "modularity" does asp have? Can I write classes? Or "com" what can I do? which advantages exist with these paths: classes, com, etc.
<% Dim objMainItem Set objMainItem = New ItemContent objMainItem.item_id = 1 objMainItem.Open() %
and the class ItemContent creates a recordset based on the item_id passed in. Each item record contains the fields (header,label,content). I would like to reference the fields in the following format
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?
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.
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:
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?
I can't seem to figure out how to include them, nor find any reference to it in msdn.
Is there a way to do this? Or should I create a slew of Session variables? Code:
Create the following code from database but does not validate on enter - I am using ShadowWizards validation code.
<Input fields so work however I will need dropdown and radio buttons to be validated also.
I really like the work ShadowWizard has put in and would like to continue in the same neat, cleaver coded way!
I did validate the few fields with ASP but Yahoo toolbar stops people going back on forms and therefor would not work on all PC's, typically the bosses and now he seems to want it asap so any javascript solution? Code:
I have a front end with all the code and a backend with some tables. Want to convert this into website database. Most probably convert the frontend into ASP. Is this the only way? Can one use the VBA code inside ASP with translating the VBA into ASP?
I need to do a loop with some criterias that depends on an earlier database query. I tried to do it this way, but it seems not to accept that the do is inside the if:
if not objrs.EOF then Do until updatearray(0) < objrs("updated") else Do While not fso.AtEndOfStream end if Blabla my repeating script here... Loop
I'm getting this error:
Microsoft VBScript compilation error '800a03fb' Expected 'Loop' /x.asp, line 46 else ^
It seems somehow that the do is "stronger" than the if statement, as it didn't even help doing it this way: Code:
I've inherited webmaster duties for a website done in ASP.NET. After much trial and error I've figured out the architecture of the site, and have a template for the area of the page that contains the content. I need to pop in a dropdown menu, nothing fancy, like the one on this Post New Thread page for "Category".
Does anyone know where I can get the syntax for one? Or does someone know ASP.NET and can write out a simple dropdown menu code for me?
I need to make a search to search our database that can be put on different customers websites. So I was planning on making the search a reusable asp.net control. But a lot of our customers websites are written is ASP. So Is it possible to call an asp.net control inside an asp page?
We need to display certain websites inside a frame on our website and I use the response.redirect command in VBScript. The problem is that some websites take over the whole browser, how can I stop this and force a website to be loaded inside a frame?
