Random Images Usin Array
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))
%>

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>

I come from a PHP background. I'm modifying a client site that uses some critical ASP code in the backend, so for simple frontend stuff I need to use it too!
I need to make sure that certain images from a random rotation only appear on certain sections of the site licensing issues. Is there any way to easily grab the name of the file that's currently loaded? I want to run some form of regex on it to check for certain words.

I have a bit of a problem.
Basically I have a homepage, when the page loads up it will display images.
However, the images are dived into three groups, as seen below.
Group1 - Image1, Image2, Image3
Group2 - Image4, Image5, Image6
Group3 - Image7, Image8, Image9
What I want is that every time when someone enters the front page, it should pick a group and display that particular set of images on the homepage.

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?

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 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!

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 dump the entire recordset into an array:
If not rs.EOF Then
aEmp = rs.GetRows()
Contents of the array are in this order:
EmpID,EmpName,Indent,Sub_ID,Lft,Rgt,MgrID, LastName
This query sort on the basis of Lft and Rgt columns.
The name of the array is: aEmp.
My question here is how can I get only the LastName from the aEmp array into another array so that I can sort the names alphabetically and then display the employees in the alphabetical order.
Or is there is another way I could this by using the same array while keeping the lft and rgt sort of the query? If I sort based at the SQL query level, I can see the names sorted by the lft, rgt and lastname, but since the lastname is at the end of the sort list - it does not appear alphabetically.

In working with arrays, I have found that I am unable to dimension and array
with a variable that has an integer value but I can redimension one this
way. I haven't see any information that tells me if this is a requirement,
although it appears to be because I get an error if I try it.
Ex.
Dim b
b = 10
Dim a(b) ' this errors out but
Dim a() ' this
Redim a(b) ' works

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
End Function
%>
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

I 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)?

I set up a random code for people registering with my site.....
letters="1234567890abcdefghijklmnopqrstuvwxyz"
for i=1 to 16
Randomize()
rNum=Int(Rnd()*36)+1
code=code&mid(letters,rNum,1)
next
but for some reason it sometimes saves code as an empty string. When I register a fake name, ie zzz, it seems to work fine, but for some of my members is saves as an empty string.
