I'm trying to set up a quick if/then/else statement for when the database field returns no results. I'm not getting an error but when the field is EMPTY it still executes the ELSE statement.
<%
If rsOffice("FloorPlan") = Empty Then
Response.Write ("Not Available")
Else
Response.Write ("<a href=" _
& rsOffice("FloorPlan") _
& ">View</a>")
End If
%>
How the heck do you work out what is actually in a db field that appears to be empty? I have fields that appear to be empty but do not seem to evaluate to empty or null, so test using IsEmpty or IsNull are useless, I 'm guessing it contains spaces or non-printing characters of some sort but how do I test for these?

if content = "" then
alert1 = "content field is empty"
else

I have a registration form that I'm making and I need to get the count of available spots for each class session. I can't get the array to return something like "0,0,0,0,0,0". Is there a way to do this? There are 6 total classes and they are named 1, 2, 3, 4, 5, and 6.
When you start out, each count will be 0 (meaning no one signed up yet) which makes the openSpots variable equal to 35 (maximum # allowed). Code:
I am writing a small ASP booking engine which allows users to book a ticket provided the num_tickets field in my db table is > 0. Each booking causes the num_tickets field to be decremented. So if a user tries to book when there are no tickets left he gets an appropriate error message. However, if a user books the last remaining ticket and the num_tickets field is set to 0, he can simply hit the "back" button and book again (which decrements num_tickets to -1 and so on). Is there a way I can make the page refresh or expire to stop this from happening? is it a sessions problem?

View Replies View RelatedI'm trying to retrieve information from a field in a database, which contains data, some of which are the same. ex:
let's say the table is called "Person_info" and there are 5 rows of info with a different person's info.
let's say i want to display the info in the fields called "City" but there are duplicates ex:

I thought about setting up two tables. One that houses the dynamic question and the other to house the answers, but I'm not sure if that will work.

I have a login page where I have three different ways to authenticate a
user.
1. Use integrated authentication and read the server variable AUTH_USER and
then verify if this is a valid user from a database. If OK I write some
session cookies and then re-direct to another page placed in the same folder
(which will read the cookie and verify that it is valid). This works OK.
2. Use anonymous login where the user is typing in a username/password which
is checked against a database and if OK I write session cookies and then
re-direct to other page which reads this cookie. This also work OK.
3. Now we read another server variable that is set by a third party oracle
product (don't know much about this product but when I print the value of
the servervariable it is OK). I write some cookies and then redirect to
another page. When I read the cookie now it is empty. If I read the cookie
just before I do my re-direct it is OK but after the re-direct it is empty.
Do you have any sugestion why the cookie becomes emtpy after the re-direct
in the third case but not in the other two? It is the same code doing the
actual reading/writing of the cookies in all three options above.
