Checking If A Cookie Has Already Been Set
I just want to check that i'm not going crazy.. I want to check
whether or not a cookie has already been set and so I am using the
following code.
cookieValue = Request.Cookies("CartID")
'if cookie hasn't already been set, then set it!
If cookieValue = "" Then
Response.Cookies("CartID") = "3"
Response.Cookies("CartID").Expires = "Jan 1, 2005"
End if
I have also used IsNull yet both just don't seem to work.... am I
missing something here?

I tried to post this last week, but never saw it, so I hope it's not a
duplicate. (Sorry if it is.)
I am rewriting our member log-in page in classic ASP from PHP. We will be
switching platforms next month. Every member has an access number to log in.
Once they have logged in, if they accept it, a cookie is provided so they do
not have to log in again. When the code is supplied via the cookie or form,
it is validated against a database file to determine the level (customer,
distributor, etc.) and the page is built accordingly. If the code has been
inactivated or is no longer valid, appropriate messages are supplied. Pretty
basic stuff.
The first thing I want to do is to check if the cooky exists on the client
computer. PHP had code for this, but I'm not sure I'm doing it correctly in
classic ASP. My opening code is below. This is before any HTML on the page,
as I have to determine if cookeis need to be set or deleted before the page
opens. When I run this on my IIS server here, the page displays an error 500,
but no hints as to what line the error is in. Can anyone help. I suspect it
is because at this state, the cookie does not exist, as it is my first
log-in.
If Request.Cookies("kc").HasKeys Then
bCooky = "S" 'Cookie exists, set flag for cooky set
strCode = Request.Cookies("code")
strSource = "cookie"
ElseIf Not IsEmpty(Request.Form("code")) And Not
IsEmpty(Request.Form("submit")) Then
strCode = Request.Form("code")
strSetCooky = Request.Form("cooky")
strSource = "form"
End If

I have a login page that sets a cookie on a successful login.
When I set the cookie to "time-out" after, say 5 minutes, it transfers to the logon page again, but how can I check if they were directed there because they weren't logged in initially or if they were redirected there because they were timed out.
I want to display a message saying, your session was timed out, please login again.
How can I check if the cookie has expired?

When I set a cookie in global.asa in the sub session_onstart, even if
I have "privacy" in IE 6.X set to "block all cookies" the cookie is
still set, and I can get it on other pages.
I can't find an article that addresses this as a specific issue. Why
does the browser get the cookie when it is set in the session_onstart
event even when I have "block all cookies" set?

I want to know what's the differences between session cookie and regular cookie.
In ASP, when we create cookie, we do the following to identify an user:
Response.Cookies("name") = value
Is this regular cookie? How about session cookie? and when to use which?

I want to check whether the value in recordset is "=> 3 ".
I try "If rs => '3' then...".
But it doesn't seems working. Can I can't check the condition by using the recordset like how i written above?
Or do I need get the value in recordset and assign to a variable in order to check the condition. Please advice.
Let say my rs now stores a value of "2". Can I check with the following code.
[code]
set rs = server.createobject("...")
rs.open "Select...", objconn
if rs >=3 then 'THIS LINE DOESN"T SEEMS WORKING
....

I'm trying to qualify email addresses. Is there any reason why the following line would not catch an email address beginning with "www." ?
ElseIf Left(Session("em"),4) = "www." Then
I put in a dummy email address: www.mydomain@aol.com and it goes through....
<%=Left(Session("em"),4)%> does reflect "www."
why?

Is it possible to have an ASP page which checks if a user is in a certain group in Active Directory (AD). For example jbloggs is logged in and belongs to the group "project_allowed". When jbloggs goes to project.asp it will allow him access
However when jsmith is logged in and belongs to no groups and tries to access project.asp it will deny him access.

The script is designed as a form validator which checks fields for various criteria and then sends a mail with the form contents. Since 40 different forms will be plugged into this script, there needed to be complete seperation between the two.
I've managed it so far by checking for required fields by putting the word 'required' into the name of the field. The script then sources out any fields which has this text and checks them to see if they are filled out.
The problem I've come across now is that I need to check for field length. My idea was to put the amount of characters needed into the name of the field in the form and then have the script check with a Reg Exp. However, Im not too sure of the regular expression needed to check for this.
Can someone suggest one? The one I have at the moment is [1-14] but say I had a field like this: <input type="text" name="passwordrequired12"> That would match bout for 1 and 12. Any ideas?

I am a somewhat beginner in ASP. I would like 2 know how do I check whether a recordset, that was fetched from an MS-ACCESS database through a 'SELECT' query, is empty or not??
The scenario is that I m making a form where users can register for my message board. The form will take in all the details and pass on to another asp file which checks whether the username is already in use or not. If its in use then it says that Username in use else the page is displaying error.
I m using the following sql.
"select * from members where user='" & username & "'"
The error is something like record cannot be found. Either EOF or BOF or the record was deleted.

I have a simple question. Can you check if a number has been passed through a form? For example I making a website for a property letting company and they upload the property themselves. But if you you put in text into the rent field, it throws up an error when adding to database obviously.I do validate the in put before adding it to the database so was thinking about another IF statement checking that a number was entered before they get as far as adding to the database and throwing up errors

I have a value in a field. The field name is Advice.
The value in this field is "abcdef"
I want to to add the value "ef" to that field only if "ef" is not already in the sequence.
If "ef" is already in the sequence it won't add it.
If i change the value manually to "abcd" when i run the code it will see "ef" is not there then add it so the field now lists "abcdef"
This is the the pseudo code:

I would like to be able to check what the variable is, for arguments sake,
the letter 'a' or the letter 'z'.I have sent the query string to this,
stringone = Resquest.Querystring("one")
Then later on, I wanted to write different things depending on what the
query string returned.
IF ---the stringone IS the letter 'a' THEN
DO THIS
ELSEIF -- the stringone IS the letter 'z' THEN
DO THIS
END IF
but i dont know how to check whether the string is = to the letter 'z' or
the letter 'a'.

I use ASP to check users data they submit. In particular, I'm checking for credit cards and I also use a server component DynuCreditCard. It basically affirms that the number "could be" a real credit card number.
Anyway, I cannot get through the website without having a legit CC#. None of the handful of testers that help cannot get through without a legit CC#. About once a month some user gets through with a blank credit card field. How do you troubleshoot something like that? I can't replicate the problem. Do you just say... "oh well... there was a computer glitch"...? How can I approach this problem?

I have a script which loads picture url's (these are on a compeletely different server) from a table and displays them on my page along with the rest of the data. Unfortunately, the folks who supply the data for my table don't always have the correct url's in the picture column.
Does anyone know a way to ensure that there is actually something to display? I guess it would entail something along the lines of checking for a remote file? How do I do that?

I would like to inquire how would it be possible to use asp to check the format of the excel being uploaded? Like the first row in cloumn A is named Results, column B is named Example and so on.
I've already able to use asp to to extract the data from the excel and insert them into the access ab. Now I would like to know how to be able to check the format of the excel file being uploaded, if it is the way i want then it would proceed to insert the values into the access db, if not the user will be informed that the format of the excel file was not the standard one.
