Randomize All Records
I was asked to create a test with 50 questions using MS Access (that's all we can afford). All question will load then show in random order (no duplicates, plus a link for the next question) then provide a "Thank you!" page at the end. This is so even when two people take the test they will have all 50 questions but each in a different order.
I've found several samples, some would let display the questions but in the same order everytime, while others would randomize them but with duplicates and I would'nt know when I got to the end because it would keep randomizing all day long.

I am veiwing a set of records from Microsoft Access in asp. The records are in alphabetical order but I would like them to be randomized.
This is my code as it is at the moment. The Database is called tourguides.mdb and the table is called Cat1. I hope this is enough information. Code:

how can i randomize pages ?
Eg. when a user login and he click on a link, he will come to a start page(start.asp) and when he click on the button continue (take_test.asp), he will get the randomized page (question_1.asp or question_4.asp...question_3.asp etc)

I'm using a randomize function to display a different featured product, but there are certain items that I want to omit. Here's the code I'm using:
<%
Set conn = Server.CreateObject("ADODB.Connection")
conn.Open "Driver={Microsoft Access Driver (*.mdb)}; DBQ=" & Server.MapPath("/theDB.mdb")
randomize
rdm=int(rnd*15)+246
sql = "SELECT * FROM kbs WHERE kbs.id = " & rdm & " AND kbs.subject NOT IN (20,21)"
set rs=conn.execute(sql)
%>
It's selecting a range of product IDs and it's s'posed to exclude all IDs whose subject is either subjectID 20 or 21. It works fine except when it comes to items with those subjects and then it displays this error message:
Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.

I want to do something that should be simple, it is in php, but i can't seem to find any array functions in asp to do this. I have an array with x number of items (the x may change, could be 10/50/etc.) that will start with 1 and end with x.
For example (excuse my poor syntax):
myArray[0] = 1
myArray[1] = 2
myArray[2] = 3
myArray[3] = 4
etc.
What I want is to call a function and randomize the array as a new array, so for example:
randArray[0] = 3
randArray[1] = 1
randArray[2] = 4
randArray[3] = 2

i trying to generate randomize number between in the range of 1 to 9999 using the below code. DNum* is between 1 - 9
RandValue = CLng((2^7*(ID1Num1))+(2^6*(ID1Num2))+(2^5*(ID1Num3 ))+(2^4*(ID1Num4))+(2^3*(ID1Num5))+(2^2*(ID1Num6)) +(2^1*(ID1Num7))+min1+min2+sec1+sec2)
then i put the randvalue where is usually generate number between 400-to-1500 into the below formula, any suggestion on how to improve the below code?
num_pmax = Int((9999 * Rnd) + 1)
num_pmin=1
value1 = Int((Num_pmax-Num_pmin+1)*Rnd+Num_pmin + RandValue)

i trying to randomize a string of text inc. number and alpha. e.g. 024053J
what is the approach to generate a few integer numbers from this string "024053J" ?
i tried to this way of randomize but not very efficient as in sometimes the user will get the same numbers back when the page is refresh.
So i thought to use a string of text to generate the randomize numbers.
randomize()
num_pmax=100
num_pmin=1
r2=Int((num_pmax-num_pmin+1)*rnd+num_pmin)

The problem concerns 2 tables, cart_products and cart_shoppingcart.
Cart_products contains all the product data (eg, prices, product's key name, etc), but most importantly, it contains the quantity of stock (prod_quantity) for each item.
cart_shoppingcart contains all of the user's items in their shoppingcart, including those that are part of an (customer) order; these have the order_number to differentiate from those that aren't in any order (their Order_number is 'no_order', the others have the order number).
Now, what I want to do is this:
For every item in the order (ie, every entry in cart_shoppingcart that matches the username and order number), take the quantity (x) the customer is ordering, then take the quantity of stock remaining (y), then subtract x from y to create the new stock level (z) and update the appropriate record in cart_products with z (all this with SQl preferably).
I was thinking of using a Do while loop, but realised that it wouldn't work as I'd have to use several SQL statements and then I'd run into a problem the minute ASP reads "objrec.movenext".

I'm trying to pull the last 5 records from my database.
<% j=5
rs.MoveLast
While ((j>0) AND (NOT rs_article.BOF))%>
''Execute HTML and data insertion here
<%rs_article.MovePrevious
j=j-1
Wend%>
Everytime I attempt to run this code, I recieve an HTTP 500- Internal Server Error. It tells me no more than that. I know that my connection settings are OK because when I move forward through the database (first five records), the code executes without error. And yes, my Cursor type is Dynamic.
Alternatively, I would also like to know how to add new recordset to the beginning of a database rather than the end.

WHILE NOT rs.eof

I'm getting this error message.
You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '3 FROM rangliste ORDER BY Oakies desc' at line 1

Does anyone know if it's possible to use the records stored in an Access 2002 database to log users into an ASP.net page? I'm trying to code it in vb.net but im not sure how it could be done. Basically I think I need 2 text boxes on the ASP page where the user can enter their name and password.
I then somehow need to retrieve the name and password from fields in the database (using ADO.net i think) and compare them with those entered by the user. If they match then I want to load another page, and if not then I want to display a message saying login details are incorrect.
Any help on this subject would be much appreciated- the fields i have at the moment are called 'User' and 'Password' in a table called PERSON.

Still working on my soccer database, I have a list of 100s of teams and want to give users various ways of accessing the information. One of those methods would be via a drop down box which would have
A-F
G-M
N-T
U-Z
If a user selects a-f how could I write my sql statement so that it pulls out the relevant teams, in alphabetical order, that begin with the letters a-f?
