Writing Array Of Random Numbers To A Database
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 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.

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: ....

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 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?

What i would like to do is to write them out and put a "X" where the days

For a simple search of a help desk application I've written, I'm querying text fields in two tables. One table is full of help desk calls (ids, where they're from, simple description, etc). The other table is full of messages that are related to a call (updates, reasons for closing, etc.) and has the call id as a foreign key.
I've got some sql queries setup to get a list of all call ids that match a search term. Is there a built in way to sort the results to make sure they're unique? I know I could do it manually in a few lines of code but am always looking for the easiest way.

I have read 10000 opinions on returning random records and I am more
confused now that before I started. I have a small access db that will
contain 20 or so rows with 3 or 4 columns. I like to return a set of 6
distinct rows and display the columns in html. I have seen response.write
and loops but can't I throw the 6 random rows in a array and pull the data
as I need it in the page? Examples?

I'm trying to have my program randomly select one of five images. I think my syntax is correct (that is it isn't giving my any error messages and the page loads with the image being replaced by a broken link 'X' box), but I don't know how to display the image to the screen.
Should the response.redirect part automatically display it to the screen or should I have it in some tag like <td><img scr ="lrandom"></td> within my table?
<% dim array(5)
randomize
array(1)="img1.gif"
array(2)="img2.gif"
array(3)="img3.gif"
array(4)="img4.gif"
array(5)="img5.gif"
upperbound=ubound(array)
lowerbound=0
lrandom = Int((upperbound - lowerbound + 1) * rnd + lowerbound)
response.redirect "images/" & (Array(lrandom))
%>

I'm a newb - so if this is a stupid question, my apologies.
I have a simple form that users fill out and then that info is written to a database. What I'd like to do is perform a calcution on a number and then write those numbers to other records in the database.
So for instance, if someone enters 12 in one field1, it would multiply that by 3 and that would be saved as field2, then mulitply it by 45 and that would be field3, then add field2 and field3 and save that as field4.
I was thiking of passing the form variables to a second page instead of writing them to the database, then using variables in the second page to perform the calculations and then have the second page write all the info to the database, but I thought there had to be a better solution.

I'm having some problems writing files to my Access database using ASP. I have a table with a couple of fields, one being of OLE datatype, that holds the file. I'm able to write and read small images, but I'm getting corrupted files when I try Word files, and my code is erroring out when I try to writing pdf files.
I think I've found the problem with the uploading of the pdf file (I think I need to adjust some IIS setting to allow larger file uploads), but I don't know what's going on with the word documents. They are small, so upload fine. Does anyone have any experience writing files to Access?

I'm trying to create a portion of script that would select x (variable) number of random records from a table.
in PHP, I could do this pretty simply with a line like, "select * from table order by rand() limit x", but the solutions I've seen so far for asp and access involve things like 40 lines of code, selecting the entire contents of a database, creating temporary tables, etc.
Is there any quick and dirty way of doing this?
