Generate Random Number Between 1 & 5
I want to display a random banner from a selection of 5 banners. So if number = 1 then display baner 1 etc. My code is as follows:
bannerCount = bannerRecordSet.RecordCount
Dim bannerSelected
Randomize
bannerSelected = Int(Rnd * bannerCount)
The above code works although it never seems to generate the value 1, ie 2-5. Also when I refresh the page sometimes a random banner is displayed and other times I get an error. Is this because I am generating a value outside 1-5? Code:

I'm trying to generate three random different numbers to display three images on a page without repeating them. I can't seem to be able to get them to always be different. There's probably some simple solution, but I can't figure it out.

I need to be able to create some license keys for an application. Ideally
these wouldn't be too long in length (ie, easier to remember/type in), but I
would like them to be auto generated and a check made to see whether or not
that key has already been used, something which could generate up to about
10000 keys (or more if the string doesnt have to be too long) would be very
useful.
A combination of letters, numbers, upper and lower case is needed.
I could sit here and start plugging away at this, an array for numbers, an
array for letters, a random test for uppercase/lowercase etc, but it occured
to me that I'm probably just reinventing the wheel a bit here, someone must
have done this before!
Has anyone produced anything similar to this in the past?

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 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 am creating a Change Management system and need my ASP script to be able to generate a number as an incident number for example for me automatically. The number would be stored in a MySQL database and the language I am using is ASP.
Can I create a column in the database that is a Primary Key and is auto_increment, even if I have already got another coulumn that is the ID column, which is a primary key?

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?

x = ROUND((0.9+1.005*RND()-0.4),1)
y = INT(y * x)
This is what I'm trying to acheive:
- "Y" has a preset value between 1-100
- "X" should be random between 0.8 and 1.2
- "X * Y" is the final value of "Y" as a whole number
What I'm struggling with is getting the value of X to be random between 0.8 and 1.2....

I need to create a random number, or even better, and random combination of letters and numbers, to be used as a type of security key for changing a user's password on this site i'm working on. Basically, the user fills out this form which sends them and e-mail w/ instructions on how to change their password (pretty basic, lots of sites do it).
In the e-mail of course is a link which links to a page with querystring values that include their customer number, the action (reset password), and hopefully this "key." What I'd like to do is have the key written to a database when the e-mail is sent and then deleted when the password is changed. So, how can I generate this key. I think I can take care of the writing to/deleting from the database.

I'm trying to create a random number that has to solid letters at the beginning followed by 8 random numbers (DN13523781) This number also can't be in use alreaddy which means it can't alreaddy be in a colum called number in the database.
I can do the letters followed by one number, but I can't figure out how to get 8 numbers in a row without getting the same ones over and over(88888888)
I also don't know how to check if it's alreaddy used in the database.
Also does someone know how I can prevent the same number from being produced before it can be added to the database at an other location/pc.
I'm building an online store and I want to give people an order number when they order something. Code:

Does anyone know how to code in a very simple random number generator?
Basically, my ASP site is linked to an SQL d/base. What I want to do is have a "Random quote of the day"... the R.N.G. should spit out a number, and that number references the random_quote_ID in the d/base and spits it out.

I have this simple application that I put together using ASP. It has an html form that submits to an access database through a simple ASP file. It’s a survey form basically. One of the departments here wants to get some feedback from their students and in return for filling out the survey they will be entered into a drawing for a gift certificate. The catch is that the survey is anonymous. What they want to happen is each person is given a unique number at the end of the survey and they will pick one of those numbers randomly to see who the winner is. How can I possibly do this? I am stuck.
I think I may know what I need to do:
Pull a unique number from a database and post it onto the HTML form near the submit button. Notate on the page that the user write the number down and when they hit submit it is inserted into the database along with the record. I have absolutely no idea how to do that.
The HTML form submits into the database using this "add.asp" file:

I have used:
set typ = server.createobject("Scriptlet.TypeLib")
to create a random string of 36 characters. However, is there a way to
create a random string of digits in the length I request? Perhaps a string
of 20 digits with a few asterisks thrown in for ease of typing?
for example:
4515-81301-75454-45136-1
Would this be reated with RegExp? And how?

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!)

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.

if (theRandom<10) then theRandom = "0" & theRandom

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:

200701-0001
200701-0002
200701-0003
Now each master batch can have multiple final mixed batch like
200701-0001-01
200701-0001-02
200701-0001-03
and this record is inserted in to fmix table.
so i have a form in which i have a dropdown menu in which all the master batch is listed,
i select 200701-0001 and that value is passed to next page where i will enter other fields data and insertion to my fmix_no will be done automatic like 200701-0001-01, 200701-0001-02 and so on,
how to achieve this
so in short each master batch will have more than one final mixed batch.
