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:
I have to Execute a User Defined function from ASP page and also the function returns a varchar. Could someone help me out with the code for this.

My Intranet homepage has four content-blocks of information. Each content-block has specific type of information (i.e. HR stuff or international stuff).
I'd like to add more of these content-blocks an give our employees the option of choosing which four they want to see.
Most portal technology offers this, such as My Yahoo. What kind of technology do I need to look into? Cookies? Are there any scripts that I can use to assist with this?
This is my user-defined class
class ABC
public CC
end class
I make a instance of it and store it at the session
set ee=new ABC
ee.CC="hi"
set Session("myobject")=ee
But when i retrieve it and access the property of my
object, it said that The object does not support this
property or method, is that ASP cannot do this, or my
code has error?
set eee=Session("myobject")
response.write eee.cc
I am looking to personalize my Intranet homepage were the user has the information they want on their page.
For example all their fav sites on the homepage, like the news headlines, email account already open for them, any suggestions of how to start or the best possible recources to use.
I am trying to get the list of all user defined tables from the Access database. If I use the following query in Access it's working fine and getting the result. But if I am trying to execute the query in ASP page, it's not working. I am getting an error ([Microsoft][ODBC Microsoft Access Driver] Record(s) cannot be read; no read permission on 'MSysObjects'.)
Can u please tell me the reason.
SELECT MSysObjects.Name AS TableName
FROM MSysObjects
WHERE (((MSysObjects.Type)=1)
AND ((MSysObjects.Flags)=0));
If you have anything, to extract user defined tables, please tell me. Either one works out for me.
How does one create user-defined objects in ASP? Sorta like the response and request objects, where you can do response.write, etc.
I'd like to create my own object called Customer, so I could do Customer.firstName, Customer.lastName, customer.age, etc. I couldn't find any helpful info on this topic on the Internet or in my ASP books.
I'm forced to use legacy ASP for a new project i am working on and seeing as how I never use ASP I needed a little help with something.
I need to create a function with optional parameters. I know in .Net I can use the "optional" keyword in the function definition to create optional parameters. can this be done in ASP 3?
How to get/set and send the HTTP Headers(user-defined) coming from another domain/site]
In one SMS gateway project i need a great and urgent help from u all. There,the Service Providers sending the data thru "HTTP Headers" (For ex.sms-Id,sms-source [user defined]).
So i need to get and parse the name value pairs, and need to respond/send the same way as coining the "HTTP Headers" (For ex. sms-Id,sms-destination,sms-msg [user defined]).
How can I give a user-defined object session scope? From
http://www.microsoft.com/windows200...asp/iiwaobu.htm
I gather that it can be done, but there are no examples. Simply setting
Set Session("tag") = new MyClass
doesn't work.
ok - this works:
Dim X
X = CreateObject("Scripting.Dictionary")
X.add 1, "Hello"
This doesn't....
Dim X
X = CreateObject("Scripting.Dictionary")
Class Aprivate VEnd Class
Dim B
B = new A
X.add 1, B
Can anyone tell me how to make this work?
I've searched over 1 hour on Google and elsewhere and haven't found
anything.
I'd like to find a way to get the real active user count on our website.
THe main problem I have is when a user quit with the "X" the counter will be
decremented of 1 only when the Session.Timeout will be expired.
im tryin to secure my application. i want the application to send the user back to the login page if they have not logged into the system. do i use the global.asa file or is there a simpler way to do this?

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?
View Replies View RelatedI'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.
View Replies View RelatedAssuming I create an object as below
<%
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
<%= objMainItem.header %
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?
Suppose if I am using two classes in my code Say C1 and C2 then is there some procedure or special way to use them one after another.

Set b = Nothing
The Class C2 doesn't work. Any idea Why?
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'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))
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 have one application folder containing all ASP code files. I want host multiple sites pointing to same code. Can I do this ? If YES then how I can assign diffrent global.asa to each application...
View Replies View RelatedI can't seem to get error handling to work from inside my classes. On the outside it works but on the inside it doesn't. Any thoughts?
if err.number <> 0 then response.write "errors" end if
I'm trying to catch all the errors as I go and I can't do that if it won't work on the inside of my classes.
Here's what I want to do.I've displayed records from the Db to a page called Inns.asp.
Among those records are COUNTY, CITY, STATE, ZIPCODE.
I created four asp pages called CountyInns, CityInns, StateInns, and ZipcodeInns.
They all display respective records with links to a redirect page. That's where I get stuck.If I have 50 records, say, displayed, i.e., COUNTY, how can I run a script against all the possible counties, without having to write a script for each and every city within that county?I do things somewhat differently, because this stuff is too tricky for me. It doesn't come easy but I usually get it right after a lot of help and attention. I bet there are other ways to do this but i'm not sure I can learn it any other way than the way I do it. Inns goes to CountyInns which leads to CountyInnsRedirect which (hopefully)contains a script for individual County display.
I am processing a form and I want to double check that a field is defined so that no error occurs. How do I check if a key exists in a collection (the Request.Form collection)?I do not want to process all of the fields in the form, so I do not want to use "For Each x In Request.Form". I process a certain list of fields and just in case the field was left out, I want to prevent an error from occurring from trying to use a key that does not exist.
Code:
For Each x In arrayFields 'arrayFields contains certain field names
'verify that field actually defined
If [field is a key in the Request.Form collection] Then
stringTemp = Request.Form(x)
'do stuff
End If
