I've got a realy wierd server problem - everytime i ask for a random number using rnd() i get 0.7055475. This problem just appeared the other day. I hadnt changed any server or os settings, however i have recently recieved a 6 part xp pro update... - has anybody come accross this before?
View RepliesI 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?
trying to get a random number from 0000 to 9999, is there an easy way to do this? i'm using this for a unique filename and want it to be 4 digits from 0000 to 9999.

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....
How would you go changing a random number generated into a item drawn from a database with SQL....
View Replies View RelatedI 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:

View Replies View RelatedI 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:

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:

View Replies View RelatedI 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.

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 have a client asking me about random images on his site, basically I am using the following code:-
<%
RANDOMIZE
Response.write("<IMG SRC='../gfx/bg-img0" & INT((3)*RND()) & ".jpg'>")
%>
Agreed its not the best code, but he is finding that the same image could be repeated like three times in a run.
I have an include file which displays the image, and the random script is placed inside that include. So when he is going from page to page this is where the issue lies.
Can anyone help me out here, is it even possible to have a different image load each time, and not have them repeating.
I am using random number to be used as a unique identifir. Since random numbers are in decimals I am using going to convert it into an integer and since I need to append this Id into my URL, I am converting it into a string. SO my formula looks like this.
CStr(Int((Highest-Lowest+1)*Rnd+Lowest))
S0 now every time a new record is generated would this formula generate a unique number for unique identification in the table. I can't see how it can do it. Say A user is assigned a random number; then another user subscribes so how would the server determines that the random value assigned to next user is not already assigned to any other user.
In case if this can't work (a unique ID for every user) then I'll stick to this very same formula and after the random number is generated, I'll check this number with the table in the database and see whether it's been assigned already. If yes, I'll request another random value, if not then I'll go with it. Is this the right strategy?

I have the below ASP function to display a random image from a folder.
<%
Function RandomImage(strPath)
Randomize()
If Right(strPath, 1) <> Chr(47) Then strPath = strPath & Chr(47)
strPhysical = Server.MapPath(strPath)
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.GetFolder("C:Inetpubwwwrootpag-siteimages
andoms")
Set objFiles = objFolder.Files
For Each objFile in objFiles
strFile = LCase(objFile.Name)
strFiles = strFiles & strFile & vbTab
Next
strImages = Split(strFiles, vbTab)
If UBound(strImages) > 1 Then
RandomImage = strPath & strImages(Int(Rnd(1)*UBound(strImages)))
End If

and this places the image in the HTML
<img name="Intropic" src="<%=RandomImage("images/randoms/")%>" width="211" height="158" alt="" />
but sometimes the script places a ._ before the image file name in the outputted HTML?
I'm afraid I have a technical problem here. Basically what happens is that I'm getting some random errors(like Type mismatch... etc) that shouldn't under normal circumstances occur. Then I connect to my server via remote desktop and Recycle the application pool on which my asp pages run. Errors then disappear

View Replies View RelatedI want to take 3 records from a database. The selection must first take any record marked as priority and then random records (so there could be 3 priority records and no more or 1 priority and 2 random etc)
My theory is to build a recordset filtered by records marked priority, and if there are less than 3, build a second recordset of all the other records.
Questions
1, how can I select random records form the second recordset, without selecting the same one twice?
2, OR, could I write a sql statement which would randomly select 3 records from my table
3, Or is they a way I could write a query (view) in Access which would do the whole lot for me (select the priority records and then random records up to 3)?
