Display And Delete Random Numbers
I’m having problems on how to randomiz numbers and delete the ones that have been displayed.
My first step is to take some numbers:
21, 32, 35, 4, 15 and randomize theese so the ouput may look something like this:
35, 21, 15, 32, 4
My second step is to display the first number (35), then when a user clicks on a link I want the second of my random number (21) to be displayed and I also want to delete the first number (35) that has been displayed. And this routine (display number, delete previous number) should continoue untill there is no more numbers. So again, I wnat to step through all my random numbers and delete the ones I have displayed.
Example: ....

I just wanted to know whats the best way to generate 50 or say X amount of number at random without having to repeat any of the previous number...
so far I've the following:
[VBS]<%@LANGUAGE="VBSCRIPT" CODEPAGE="1252"%>
<%
function RandomNumber()
dim theRandom
Randomize
'RandomNumber = Int((upperbound - lowerbound + 1) * Rnd + lowerbound)
theRandom= Int((99 - (0) + 1) * Rnd + (0))
if (theRandom<10) then theRandom = "0" & theRandom
RandomNumber = theRandom
end function
%>[/VBS]
and then I've this in the body of HTML doc: Code:

I have a problem creating random numbers. I basically have this
Randomize()
iRandom = Int(10 * Rnd + 1)
If I do not wait a few sec before hitting the page again it will create the same random number as generated a few seconds before.Any idea why it is like that? Another way to reprocess the "bug" is to just fit F5 few times in a row and you end up with the same number being generated. Its annoying and I need some help to "fix" it!

I am developing a online test application(multiple choice ques) So for that i need to shuffel the questions randomly. eg there will be 60 Questions in total. If say 50 users are connected to it, all will be having same 60 questions but its order should be different.
i am using below code to randomly generate questions numbers but the problem with this code is it is repeating the number.I want to generate non repeatable numbers. Can anyone help me out to do it.
Dim my_num,max,min
Dim i
i = 0
max=60
min=1
For i = 1 to 60
Randomize
my_num=int((max-min+1)*rnd+min)
Response.Write my_num & "<br>"
Next

I know thats theres already a few posts about this subject but I need to create 3 random numbers of any size, I've used the following code -:
randomnumber1 = int(rnd*9)+1
randomnumber2 = int(rnd*9)+1
randomnumber3 = int(rnd*9)+1
but it always returns, 7,5 and 6..
Not very random as you can see

I am trying to create a random value between 10 and 1,000,000. I am using the following code but it is creating numbers between 10,000 and 999,999. How can I fix it.
<%
Highest=1000000
Lowest=10
Randomize
Val_Rand=CStr(CLng((Highest-Lowest+1)*Rnd+Lowest))
response.write(val_rand)
%>
The code never gives small numbers like 10, 15 500, 250, 257 etc.

I have this situation:
each user has some amount of points, for example:
table:users
user_id --- user_name --- points
1 --- user1 --- 100
2 --- user2 --- 100
3 --- user3 --- 100
4 --- user4 --- 200
5 --- user5 --- 500
-------------------
total points: 1000
I want to generate random selection of user, according to their points respectively, so the more points he has, the more likely he will be selected:
user1 in 10% cases
user2 in 10% cases
user3 in 10% cases
user4 in 20% cases
user5 in 50% cases
this percentage is respective to their points; I put some rounded numbers in the example - so total points of 1000 equals 100% - but they can have any amount of points: 1, 200, 3672 etc.

not after code, just thoughts, suppose i'm generating a random 8-digit pin number for our clients, first i'll be checking against the db to see if it already exists before assigning it. what i might do for that is getstring all of the exsiting pins at the top of the script and just keep performing an instr until i get a 0. (i dont expect to ever go above a thousand clients for this system and hopefully my initial number will be random enough that these checks are for backup/redundancy assertion anyway)
but anyway, the main problem is: i dont want to generate a random pin that is one (or maybe two) digit(s) different from another,. i.e.
11111111 is too close to 14115111 and much too close to 11111811. 11121111 is right out of the question as it can be entered as a typo, as is 11111411 because of the numpad
so i'm after thoughts on how to perform that check, i suppose if i went with the "big string of all pins that went before" check i could perform a number of regex searches on the string. i.e.
my pin is 12345678 and i dont want ony to be one digit different so i'd check the string against .2345678 1.345678 12.45678 and so on. think i just answered my own question, anyone else got any ideas? especially for the two digit case (dont want to be performing 36 regex checks do i!)

I am trying to write an array of random numbers to a database. The array part is working fine, but when I go to update the dataabse, it inserts the last value of the array into all the fields in the database .....
Dim MyValue,sqlRandom
Dim arrayRandom(8)
for i = 1 to 8
Randomize
MyValue = Int((100 * Rnd) + 1)
arrayRandom(i) = MyValue
response.write "<p> Array Value:" & arrayRandom(i)
sqlRandom = "UPDATE CarParkDetails SET FreeSpaces = '" & arrayRandom(i) & "'"
Conn.execute(sqlRandom)
next
I can't see whats wrong!

I need to generate three random numbers between 1 and 100, but they need to be different.
e.g. 3,43,88 would be fine but 5,76,76 would not.
The function I have to generate a single random number is:
function funRandomNumber(intHighestNumber)
randomize
funRandomNumber = int(rnd * intHighestNumber) + 1
end function
called by: funRandomNumber(100)
Can anyone see how this can be modified to do what I need?

I want to provide random image on my asp page. the image will display according to products searched by user.
e.g.
if user enter pharma machine in search box, in result page the banner of pharma company will display. i.e. the banner of manufaturer/exporter of pharma machine will display.
for this i have comapny info table in database
table: comapny_info
fields in comapny_info:
company_name
products (comapny products)
description (company_description)
banner (yes/no)
dusring registration, comapny has to specify whether it wants banner or not. so if there is yes in banner and prodcuts match the search string then banner will display.
this is according to the product seaarched by user.
any idea?

I have this code that displays record sets at random, but some of time the results are less than the minimum set, which is 5 records. It is less, or none at all. What I need is for the asp to display records randomly on each submit.
Currently, the asp runs so that the whole recordset is different, i.e. Random. I am a little concerned about the load on the server by running such a script....perhaps someone can clarify.

On my index page I have got an area for one product to be displayed randomly from the
database. I have got it workign, but there is one problem i cant get my head around, here is the code so far:
' Initialize ASP RND() function
Randomize()
intRandomNumber = Int (1000*Rnd)+1
strsql = "SELECT TOP 1 art_Artist, art_Title, Rnd(" & -1 * (intRandomNumber) & "*cat_ID)" &_
"FROM eventDisplay " &_
"ORDER BY 3"
The code above isnt working and its when i try and draw out more that one value, as in art_Artist and art_Title.
It works fine if all I want is art_Artist, but as i said when i try to draw out more than one value the randomize function doesnt work.

I Have searched the forum but have no solution to this problem.
I want to display my records in a random order. I loop through my records so I don't know how many records will be displayed. I dont want to count the records and then use the TOP statement. I'm looking for a better solution.
Set rs = Server.CreateObject("ADODB.Recordset")
rs.Open SELECT test FROM testTable WHERE testId = 1, objConn
Do While Not rs.EOF
Response.Write "<b>" & rs("test") & "</b>" <- I want theese records to be displayed in random order

However, what I want to do is include a request.querystring("ID"), so that IF an ID is defined, eg ID=3, , it will display the relevant (not random) information. I've tried this every way I can think and get type mismatches, etc etc. It's probably really simple but I can't see it.
<%

redim link(limit)
redim image (limit)
link(1)="xxx"
image(1)="image1.jpg"
link(2)="xxx"
image(2)="image2.jpg"

image(3)="image3.jpg"

We have the need to have a random token (a 16 char alphanumeric field) to be used as the key for one of our SQL tables. I have created a random token generator, however after only 3 months in production, it appears that we had an instance where a token that already existed in the tables was created. There are 3810 records currently in the database so it isn't like there are billions of records there.
I contacted an old college buddy of mine who is a mathematician, and he claims, assuming that random really does mean random, that the chances of getting a duplicate token are 1 in 79.5 septillion (79,500,000,000,000,000,000,000,000).
So my conclusion is that this was either a complete freak of nature occurance, or my random generator isn't really all that random. Here is the code behind how I am generating this: Code:

I am trying to generate a random number. I am using randomize and then rnd to return a decimal number between 100 and 120. This will give me a longitude. I am doing something similar to generate a latitude.
I created this on a page which refreshs every minute. I put these points into a map and they are showing up in groups of straight lines. Since rnd is time based will refreshing every 60 seconds return similar numbers?
