Checking Error Code
I'm setting up a simple competition entry system in ASP where users can enter their name and email address to be added into a prize draw. It's pretty simple stuff, with the data being added into an Access DB table.I've created an index on the 'email' field to stop the same person entering more than once (unless they have more than one address, but let's pretend that's never the case ).Instead of doing a SELECT query to find whether they've entered before, I simply want to attempt to INSERT the data into the table, and if it returns an error along the lines of "no duplicate values in the index" it would give the user an error.My question is, is it possible to display a user-friendly version of the standard ugly ASP generated error message when this error is detected? Or am I stuck with the incredibly unattractive error message we're used to?

In Kevin Yank's book, he shows how to put in error checking at various stages of working with a database: connecting, querying, etc. I presume the same general principles apply to ASP/SQLServer but I don't know the code. Can someone tell me at what stages I should be checking for errors and some generic code that I could use at each stage?

I am in the middle of writing a shopping basket which will hold 10,000 or so products. Basically I want to check the performance of my ASP code. I don't want it to keel over and die on me. I did encounter a problem with not closing connections and my site just died on me. I was wondering if you could give me any advice.

I am writing a script that lets me brows the contents of a web server. The problem is the account that is running ASP does not have permissions to every folder. Don't ask me why ... I have no idea but it can't be changed.
What I would like to do is perform a check for:
Microsoft VBScript runtime error '800a0046':Permission denied
And if this happens display an error message saying they do not have permission to view this directory. Code:

why this string fails to check if a user does not enter any data in a field?
<%
' Declaring variables
Dim make, model, description, price, data_source, con, sql_insert
' A Function to check if a field is empty
Function ChkString(string)
If string = "" Then string = " "
ChkString = Replace(string, "'", "''")
End Function
' Receiving values from form
make = ChkString(Request.Form("Make"))
model = ChkString(Request.Form("Model")) and so on and so forth...
%>

what would be the best way to error check a page after I clicked submit but before I go on. Example:
I have a page that dynamically puts text boxes & lists on a page depending upon which button I click on the main menu. What I want to do is check the text boxes for correct values (most likely before I go to the next page which is the Update page). But since I am dynamically creating the page & text boxes I don't know what the names are... I am doing the dynamic page through server side script.
This means that almost all my variables names and anything associated with the dynamic page are in the Server Side script and can't be reached by Client Side script. ok long story short which is best to error check a dynamic page before updating the info on that page. Server Side | Client Side script?

i'm making a forum, and previously i was submitting the form to an asp file, which would check for errors -- if there were errors, it would redirect back to the form with error messages to be displayed -- if it was error free, the message would be written to a txt file.
but then i wanted to put in a preview message page, and so error checking and passing values between the three pages is becoming tricky. so i'm at the point where i'm starting to use javascript to error-check, which works fine for making sure the input is good, but i don't know a good way to notify the user that there are errors with javascript. alert messages are unprofessional, and i can't just add text to the page using javascript.
i'd prefer to use only asp, and i'd prefer it if i didn't have to use an extra asp page JUST to error-check. as it is now i have these pages involved in adding a new subject:
post subject (has the form for the subject and message; the user can click either post message, which will directly write the message, or preview message, which will bring them to a page which displays the post as it would appear once written)
preview message (regardless of what the user clicks, it would come here first to do error checking, and depending on what the user clicked it would either redirect to the page which writes the subject, or display the message;
the problem is, if there are errors with the form, i need to point the user back to post subject without losing whatever info they have already entered. the only way i know how to do that is by submitting a form [i can't use a querystring because it won't maintain the message if the user entered multiple lines in the message])
add subject (this does the backend writing of the message, and is only accessed if the fields have made it through the error-checking)
any solutions in mind on how to pass the field values between these three pages?? or is there a better way i can do error checking??

After commands like:
tmpDBconn.Execute("DELETE * FROM mytable WHERE rc_id = 10" )
How do I check for errors?
Is there a way to check the results?
OR:
Set rsCatCount = tmpDBconn.Execute("SELECT COUNT(*) FROM cat WHERE key_id = 10 AND cat_id = 6")
How do I get the count? Do I use rsCatCount(0)?

I am trying to set up a staff update page for a local school and have set up a database to record it. I know the database works because I can populate it and display the content. When I went to write the insert statement I get an error that i am unsure how to solve. This is the statement. Code:
SQL = "INSERT INTO staff(first,last,email,position,phoned,job,thedate ) Values " & _
"( '" & first & "', '" & last & "', '" & email & "', '" & position & "', '" & phone & "', '" & job & "', '" & thedate & "')"

here is the code
if ((form1.Decline.value=='') && (form1.OfficeStatus == "YES") &
(form1.FloorBldgDiscStat.value=='')) {
alert('Enter value on floorbldgstat')
return (false);
}
This validation does not work when i try to update my asp page i should prompt the alert msg. My OfficeStatus field is a dropdown with value of "YES" and "NO". What i should i use to get the value "YES" i javascript. Single equal sign(=) or double equal sign (==), and anothe one is what should i use in enclosing the "YES" value. '' or "".

this is the nature of ASP scripting language that is being executed in

The call to Server.CreateObject failed while checking permissions. Access is denied to this object.
What is the reason of this error (while creating instance of the access)?. Is there any problem with my IIS server setting ?If there, how to solve it?

The employees who use it are not allowed access to the server it's
requried to sit on which means that my username and password have to be
included in the logon.asp page which I HATE! So when this fails, it
publishes my usernanme and password on the screen for the user to
see...brilliant!
Since nobody is willing to create a dummy account is there a way that I
can keep that line of code from displaying if in error? I've added the
code to this thread...

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

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?
