Generate Random String
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'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.
Here's my current code: ....

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 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 designed a website that is using an asp shopping cart script and has a flash header which i have designed to display different content depending on the query string that gets passed to it in the page url. now my problem is that my script has a lot of pages and there are many ways of going from one page to another.
what i im wondering is if ther is away that i can make an asp page directly append a query string to the url when the server generates the page and sends it to the browser.
So basically if say i had a page called home.asp when i opened this page a some code in the page make the page serve as home.asp?page=home&content=logo which would make my flash script display content according to the query string it has received.

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)

I have the following function which generates random strings:
function GenerateRandomStr(nLen, skipRandomize)
dim i, strTmp
if not skipRandomize then Randomize
strTmp = vbNullString
for i = 1 to nLen
strTmp = strTmp + Chr(fix(26 * Rnd) + 65)
next
GenerateRandomStr = strTmp
end function
But it is so happening that it is generating duplicate string which is causing the system to fail. Can anyone tell me why it is behaving in that way??

I have a database of images with captions that I need to display at random on an ASP page. Once I have pulled out my recordset, what's the best way to select on item at random from the recordset to display? Also, at first I might have only 5 items in my recordset, how can I avoid the same item repeating 3 times in a row if the person clicks refresh?

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.
<%
limit=3
redim link(limit)
redim image (limit)
link(1)="xxx"
image(1)="image1.jpg"
link(2)="xxx"
image(2)="image2.jpg"
link(3)="xxx"
image(3)="image3.jpg"
randomize
random=int(rnd*limit)+1
%>
<center>
<a href="<%= link(random) %>">
<img src="<%= image(random) %>" border="0"></a>

<%
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:

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?

I've been trying to Google this but have been getting far too many hits to be of use. Is there a slick way to generate a CSV or other Excel-friendly format and push it to the client? I'm using VBScript (and HTML and other typical stuff of course) on the ASP pages (no .NET stuff). Just a shove in the right direction is all I really need here.

I noticed that PHP have the ability to create PDF files without using any third partty componentys. Most notably is via FPDF. It generates PDF by using "pdf markups" / or ghostscripts .
I believe the same can be done via ASP too. One has to use response.write pdf headers. Has anyone succeeded in doing that? I have the intention to go thru PHP's FPDF and try to convert that to VBScript.

I trying to generate a new XML file everytime a user post a value through a simple form.
The form has one textfield called "price" and I want to save a new XML file (rewriting the file if the case) using the value entered. I don't want to append the value. I saw many turorials, but none of them work for me, and everytime I try to edit them, nothing seems to work.

I'm developing an Asp.NET system to take a CSV file uploaded via the web, parse it, and insert the values into an SQL database. My sticking point comes when I try to split() the string returned by readline() on the file.
The following code snippet works for me:
tokens = "one,two,three,four".Split(",")
for each token in tokens
response.write("<td>"+token+"</td>")
next
However, if I take the next line in the CSV, read using StreamReader.ReadLine on the PostedFile.InputStream, I receive "Object reference not set to an instance of an object." which I have narrowed down to be my string holding the line. Further investigation reveals that no other string member functions work on my line (.ToCharArray, .ToString, etc).
I suspect that StreamReader.ReadLine is not correctly returning a string, even though Response.Write(line) displays what I would expect .....

I want to create an Excel object from an ASP page. Basically, the input parameters to the Excel would be from the ASP. I know ASP and I know VBA, but I haven't used both of them together. Here's what I would like to do -
The ASP should generate an Excel report by passing 2 parameters to the Excel application (I have done this independently; without interfacing with ASP).
I know that I can create an excel handle from the ASP as -
Set MyExcel = Server.CreateObject("Excel.Application")
I dont know where the VBA code has to go? DO I have to include it in the ASP?

times). Basically what happens is every time I do this, excel does not close once I hit my back button. Does anyone have a solution to this problem? Another problem is that when I run the query it just opens excel within my browser, is there any way to make it ask if you want to save or open the file?
I basically throw this code at the top of the html doc: .....
