Destroying Recordsets
Assuming I had a recordset set up like this:
Set rs = Server.CreateObject("ADODB.Recordset")
is it enough to close out the code with
set rs=nothing
or is there a benefit to
rs.close
set rs=nothing ?

Destroying All Asp Objects
I have a website with a large collection of pages. Many of these dynamic pages use multiple objects created via the Server.CreateObject method. There are filesystem objects, recordsets, browsertype objects, you name it. I need a script that will loop through all of the objects and Set them = Nothing to destroy them.
I imagine the script would be somewhat like this.
For Each obj In ServerObjects
If IsObject(obj) Then
Set obj = Nothing
End If
Next
Destroying Sessions
Does anyone know of any issues which prevent Session variables from being destroyed when using Opera Version 7.50? I am using the following code to destroy a Login session variable and it works perfectly in IE (Mac & PC), Netscape (Mac & PC), CrazyBrowser and Safari but not in Opera.
if request.QueryString("logout") = "true" then
Session("mySession") = ""
mySession = ""
Session.abandon
end if
I don't think I'm doing anything wrong in the code so whats the problem?
Destroying Session
I have this problem on my page. Im doing my "Logoff" portion, everytime I click "Logoff" then click the Back button in my browser the previous page still appears.
Heres my code
<%
If Request.QueryString("login")= "logout" Then
Application.Contents.RemoveAll()
Session.Contents.RemoveAll()
Session.Abandon
Response.Redirect("../../global/common/login/login.asp?login=logoff")
Else
End If
%>
but I think this is not working or there is something wrong with my code.

Destroying Application Variables?
I intend to use application variables to control access to editable blocks on an intranet site. There are about 300 blocks currently and that may grow to as many as 400 as time goes along.
Using the scheme I am thinking of an application variable will contain the username of the person currently editing a block. Is there a way to "destroy" the application variable so it no longer occupies memory or is this anything to be concerned about? I don't plan to place much more than a 20 character string into the variable.
Destroying A Session And Starting It Back Up On The Same Page
I have a quick signup for a friends page, and at the end of the signup I wanna destroy all the session variables using the nice session.abandon then create two session variables for the username and password so they're already signed in, then redirect them to the index page already logged in. Problem is the session variables don't get saved on the redirect when the session has been abandoned on the page. If I take the abandon out and destroy the session variables individually everything works fine and the new session variables survive. But if I abandon the session then set the new variables they do not. Yes, they are being set after the abandon, and do exist as I've written them to the browser before the redirect. Its not that big a deal in such a small scale to delete all the variables individually, but theres gotta be a way incase it was hundreds of session variables right.

im building a page which has a few while loops. this means that im inevitably going to end up with about 20 recordsets on the page. will this slow the page down at all? its quite a lot of hits to the database/server. the results the recordsets will be returning wont be that big though.

Recordsets Vs. Arrays?
Is there a performance advantage to parsing thru a recordset verus using an array?
I'm currently trying to populate a listbox by returning data from my database, then either parsing thru the recordset until I reach the EOF, or putting the data into an array.

I have never sorted a recordset - using rs.Sort - i have no problem sorting it in SQL.

im building a site for a clinic. they want to have a calendar which displays the times for each day that are available for appointments.
at the moment i have a calendar on my page. i want to display the correct times for each day. should i use one big recordset that gets all the times/dates from the db or cycle through each day and create a recordset for each day that there are times available (some days the clinic wont be open)?
if i go with the latter option, i could potentially have 30 recordsets open. is there a fast way to execute recordsets.

I have a table that is just dumping an entire database data. I would like to have the values of the columns re-sort the data. Not the column heads for the data displayed under the column head varies.
For example, one column, Components, displays 80 components types and another column, Category, displays 40 categories types. When a visitor clicks on one of the component values, it should then display only that data. I've done this before but, it has been a very long time. I remember creating a link surrounding the recordset in my table but what was written.
How Do I Compare 2 Recordsets?
I have 2 recordsets. One contains all customer info data, the other recordset contains 1 field of customer id's.
How do I create a recordset that contains all customer information (from the 1st recordset)for only the customers in the customer id recordset (2nd recordset)?
Working With 2 Recordsets
I have two different query in my ASP page:
- the first is the list of all my users:
"SELECT DISTINCT lastname, id FROM table1"
- the second is the list of users that join a meeting:
"SELECT DISTINCT lastname, id FROM table1, table2 WHERE table2.codeMeeting = " & Request("code") & " AND table1.id = table2.id"
I want to show all the users in a table (with a FOR loop), with a checkbox that is checked if the users join the meeting (= if users is in the 2° recordset)
How can I do?
IF Statement Using Recordsets
I need the IF statement to check 2 recordsets.
If the first recordset has data within then write this to the asp page, If not and the second recordset has data in, then write this to the asp page, then finally if neither of the recordests contain data and are NULL to write 'No Records'
Closing Recordsets
I realize that sometimes you can use recordsets that were never opened (like when you're adding a record to a db) and I realize that you cannot close a recordset such as this.
But for the ones that ARE open, should they be closed first and then set to nothing?
Also,I'm trying to create code that checks if a recordset is open. If so, I wnat to close it. How would I do that?

View Replies View RelatedClosing ADO Recordsets
I have in the back of my mind and knowing the importance of using close(rsname) to close a recordset once it has been finished with, is whether any recordsets have been left open accidentally.
Is there, therefore, a way of listing all open recordsets, without specifiying the name of the recordset? ie. "For each key in recordset". Do recordsets get closed after a period of non-use?
Classes And Recordsets
Assuming 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 %
Displaying Recordsets
I'm trying to display different recordsets (which are 1 field each) as columns right next to one another. For example, Recordset1 is displayed on the left hand side of the screen. Recordset2 is displayed immediately to the right of then first recordset with the first rows or each at the same level.
Recordset3 is displayed to the right of Recordset2 and so on. There is no set limit to the number of possible recordsets (or columns to display). Imagine a spreadsheet where each column is a different recordset. How can I display that using ASP?
