i have a form by asp and database by MS access.so i want to prevent the duplicate value in empID because when i add a new employee with the same id ASP gives me this error.
Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80040E14)
[Microsoft][ODBC Microsoft Access Driver] The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again.
/employee/admin/addemp1.asp, line 48
so i want the employee to get a message like this empID already exist or somthing like this.
Prevent Duplicate Submissions
I need help ASAP. I have a form where users can fill out the fields firstname, lastname, and emailaddress. When the user submits the form, I need ASP to call out to a SQL Server database to see if the firstname, lastname and emailaddress the user submitted already exists in the database.
If they all do exist, the user should not be allowed to submit the data but should be redirected to a page saying "sorry, you have already entered that information" or something to that effect.
Is There An Easy Way To Prevent Duplicate Records Being Added To A Access DB
I am adding simple records to a fairly simple access database with the following code
rsEntry.Fields("Player1") = ShortName(Player1)
rsEntry.Fields("Player2") = ShortName(Player2)
'Write the updated recordset to the database
rsEntry.Update
rsEntry.Close
adoCon.Close
Set rsEntry = Nothing
Set adoCon = Nothing
How can I SIMPLY :-) prevent duplicate records from being added? I know I can set the index property on the fields but that mean handling the errors - not sure how to do this.
OR I could write the code to seach the DB before update - which may be the only way :-(
Is there a simple way?
Find Duplicate Before Inserting
I have my register page, which I am using dreamweaver to develop this site. I can't get my Request.ServerVariables("LOGIN_USER") to work, so I have to code something that will give a response back to the user saying that username already exists incase they try and register again.
Since I'm using dreamweaver and it likes to code lots of information in different ways I am having a hard time trying to figure where to put my if statement to start checking for duplicates for the username (which is the unique ID). Here is the complete code. My question is where do I start to accomplish this task?? Code:

I have an MS SQL database, I want to be able to create a new record based on a prevoius record, the SQL statement I have is this:
strSQL = "INSERT INTO tableX " & _
"SELECT * FROM tableX WHERE " & _
"id='1'"
The problem I have is that the primary Key (id) is set to Identity and so won't allow duplicates, I need this SQL to work but give the id value a new unique value.

Duplicate Record Error Message?
I have a booking form, called classroomform. On this form the user requests a classroom number, location, date, start/end time and number of students.
As it stands, the data is submitted via a submit button and an insert query created using Dreamweaver.
I already have various validation on the form, such as javascript which error checks for invalid times etc and asp validation which checks for correct dates etc.
However, the final touch that I'm looking to do is to add some code to the form which checks for duplicate entries that are in the database. I basically want an error check which doesn't allow the user to enter a duplicate record that is based on classroom number, location, date, start/end time.
Here's my code: ...
Inserting Record
i've tested my code and it seems to send back an error, when i'm trying to insert a record into my db (sql server)
Basically when I udpate one of the records it's fine ( I update at a certain "productID")
But when I insert a new record it sends back an error telling me that my "productID" can't be a null value?Any ideas on how to fix this?
Inserting Record
I am trying to insert a record into an access database, to just one table, using an insert form created from dreamweaver.However when i open the page, enter the details and click submit, it re-directs me back to the same page, rather than the confirm one.
The weird thing is, i created an identical page for to insert a record into another table in same database and it works fine. There is also a problem when trying to update/delete a record from the same table.
Inserting New Record
I'm trying to create a form on an ASP web page which will contain information on students and I'm working in Macromedia Dreamweaver MX. When the user wants to insert a new record and when he opens the web page to do so the form should automatically show a new Incident Report Number.
When inserting a new record For example: If the last record that was entered had an Incident No 13, the form must show number 14 by itself for the Incident Number field and the user should be able to enter the rest of the information of the student.

I am a webdesigner.We have recently taken over a site created in ASP. The site remains on the original server, but my company does the updates on the site.I do not touch the ASP at all, as I not familiar with it other then I know ASP automatically becomes html when you view it from the browser and u can save the file from there.Anyways, I edit the pages as required, new text, new photos, new links, and create new pages (any new pages I create in html if not tied to the database). I save the pages with a .asp extension and upload. This does not seem to mess anything up.
The person who hosts the site, is upset that someone else is editing the site, so he's really not easy to work with. Anyways, after uploading files, everything works fine, and then a day later, all of a sudden, any .ASP pgs you click on give the following error or similar pasted below. What I'd like to know is if these errors are because of me..and if so, how do I prevent it.
Prevent Excel
I've got an intranet application that presents a list of files in sort of a 'central repository' web page. Each file is an href in the form
<a href=file://server/share/path/filename.ext>.
When the user clicks on an excel file,it is opening within the browser,which unforntuntely confuses the heck out of them because the usual Print/Print Preview menu options are not available. I would like the user to be presented with the typical Open/Save dialog when clicking on this link.
Is there any way that I can force the browser to do the same thing as 'Save Target As', without modifying the user mime configuration in IE (another common suggestion), or hosting the files on the web server?

If you look around on the web for advice on cache-control and using 'Option Explicit' you get a paradox. Both features are supposed to be the first piece of ASP code on the page. Well they can't BOTH be first can they?
View Replies View RelatedPrevent Flooding
What would the logic be to prevent flooding? On my forum they have a timer, so if the user has submitted a post, it starts the timer, and after 30 seconds it will allow him to post again.
When the user comments, record the date in a session (StartTime) and when the user tries again, DateDiff in seconds to see if the Now() time is more than 30 seconds after the StartTime. If it is, clear the session.
Prevent Same Session Var
i tried to open Window B using window.open() from Main Window. And from Window B i open another new Window C which fires up session("topic")="something"
So i tried to open another window link from Main Window, and the session("topic") value is still the same. how can i overcome it? Beacuse im using same session("Topic") var for all the sql query statement. so if 1 window is opening and another different session window start, it will overwrite it each other.

I have a signup form.
I would like to be able to check for duplicate entries during the signup.
E.g. Check for duplicate
1. Usernames
2. Phone numbers
How could this be achieved ?

Duplicate Web Site
I have a fairly complicated web site with multiple sub-folders running on W2k server (IIS5?).
I would like to duplicate this to another web site on the same server for testing. For instance, the current root web of the server is located atF:Web. The production site is F:WebMyApp.I want to create another siteat F:WebMyAppTest.
The only thing that prevents me from just copying everything from one to the other is the links and includes of the pages, such as:
<!--#include virtual="/MyApp/Shared/Server/DbLibrary.asp" -->
<link REL="stylesheet" TYPE="text/css"
HREF="/MyApp/Shared/Style/Style.css">
I then need to go thru every source file, and change /MyApp to /MyAppTest.Is there a way to accomplish this via IIS, or by changing the way I reference the includes and link?
Duplicate Variables
I have a form with home address & business address fields.When a user goes to this form, the fields pull the information that is stored in the database,then they can update their information.
What I would like to do is have a checkbox/radio button/button that allows the user to specify that the business address is the same as the home address and replace all the business addy fields to the same value as the home addy.
So when you click/select this button, the business address fills in (if empty) or changes (if it has values) to the same values as home.Then when the form is submitted, these changes are written as normal.Is this possible and if so, can someone point me to an example?
