How To Stop User From Booking When The Database Is Empty.
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?

Is there a way to let user stop an asp script that's running? May be by pressing the STOP button on the browser or something.

I want to empty the forms fields when a user clicks on the back button. I wrote some js that will do this, but I can't figure out the right time to execute the script. If I do it on the submit form event, the values entered do not get posted, if I do it on the <body> onLoad event, the form name isn't recognized (the page posts to itsself). I also tried putting the js in a <script> tag inline just after the form, but it doesn't seem to have any effect.

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
%>

I have setup a database for user to upload product image and it name and desciption. Since there is no product upload by user, it will display this error:
ADODB.Field error '800a0bcd'
Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.
/i-Metz/iMetzAdminADs.asp, line 295
Therefore i wrote this script to counter the error:

I am trying to determine if a field in a database is empty or not. The code I have is this....
(before this I have code that opens up the database, gets the data from the table. the var "content" holds the data if any from the database.)
if content = "" then
alert1 = "content field is empty"
else
alert1 = "content field contains text"
end if
This doesn't seem to work. I also tried...
if (content) then
alert1 = "content field is empty"
else
alert1 = "content field contains text"
end if
No luck yet. Any ideas?

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 trying to create an online class booking system for a project, how can I sort out the classes so that when a user selects one it gives them the date of the next class, which would be the week afterfor example if I book a class for Thursday then I will be told that the next available class will be Thursday next week. Also if it was Thursday and I wanted to book a class on Monday then I would want it to book the next coming Monday.
The classes are changed every four months, therefore having to put these in a calendar would be extremely time consuming. Is there a calculation I can use in ASP to automate this on the basis of the above example?

I'm looking for a code already written if it is possible (as i need to do this soon)I have a database(access) and the users submit data from a asp page and it stores the values. Then it also allows the users to login to the web page using the data (username and password) inserted by the user.
What i want is that when the user logins, to be able to modify the inserted data..Perhaps the user wants to change the e-mail address. I tried doing some search in google but the results were no good.

I have been thinking about storing some data, which my users upload, in text files rather than database, since often I do not know how much information users submit for things like item description or images URL paths.
This information may be very short or very long. MS SQL Server requires a maximum field length to be set. Thus, if user enters 5 characters into 5000 character field, a lot of space will be wasted. On the other hand, the database reference would point to the text
files to read users' data and display it on page.

Is there any way to use asp to determine a users SQL Server database access rights.
I.e I have given a users data read only/ data write only in SQL server, how can I pick that up in an application so that only write only users can see a hyper link.
I know I could create a few more pages with a table in a database with various rights but I just want to read rights directly allocated from SQL Server.

I am currently writing a little gadget where users can create, delete, alter... tables in a database. Some kind of MyAspAdmin... Everything works fine as long as I specify the MSSQL-Login-Infos database, user and password.
But if I want to make it possible to switch from one database to another, here comes the problem: The user has to choose a database that he wants to work in, and type in user and password.
I need the (probably very easy) solution, how i can check if this user/password/chosen_database combination is correct. Code:

I have a page where students can choose activities in a day... this then directs them to their timetable for that day.
However, if they go back to the choose.asp page and they have already registered, I redirect them to timetable.asp - because I don't want them to change their options.
I have their username stored as a session variable and it works fine for most students - however for the example student O'SMITH-JONESMark the page falls over.
I am using Dreamweaver's 'redirect if username exists' server behaviour. Code below... Can anyone tell me how to fix this so the code is not tripping up over the odd characters? Code:

How do you stop Dreamweaver from displaying server side includes in the Design View Window? I use a include to provide my asp pages with a general layout. My machine used to ignore the include statements when I'm in Dreamweaver deign view, but today it just decided to show them. It makes it hard to work on my programs.
