Handling Unload Of Page

I have 2 pages, when the browser window is closed and depending that the user has not already taken the survey and also that the user has not declined to take the survey, i will open a survey form for the user.
Now i have links on these pages also. I only want to show this survey if the page is closed and not when the user clicks on the links (as at this time current page unload event is called too). How i can accomplish this?

Supressing the "Save password" prompt: Are there any good approaches to keeping a password from being stored client-side if auto-fill is on? Ideally I'd like to supress the prompt. The only other option I can find is to use a timestamp as part of the form name and pass it (the name as well as the value) in a hidden field to the login script.
Unique concurrent logins: Are there any good ways to prevent userX from being logged in from 3 different locations simultaneously? -I can code for a 'logged in / out" field, but that relies on the user actually login out. And if I use a variation of the "who's online" approach the user may have to wait until the seeion expires befor logging in again (suppose thier net connection dropped for a moment and they need to get back online) - At least I think this assumption is correct.

However, when I am trying to programmatically use the sql statement for the insert, I am having the following error:

I have been trying to find a script on the net that would allow me to handle directory listings through ASP. I'm basically looking to change the default generated pages when browsing directories. Eventually I would love to be able to change which directories/files show based on permissions and be able to allow uploads to current directory listings.

How do i do error handling using asp. Like taking an example i am getting this error on trying to save a record twice whihc has a primary key constraint:
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.
how can i handle such cases and where do i place the code???

I have a piece of code which causes an exception. Now i don't know why that is. I would like to know the best way to debug the exception.
I know about try and catch statements. However with these you need to have a basic idea of the type of exceptions that could occur. Does someone have a better suggestion on how to debug an exception?

I want to error handling in ASP. But i think that ASP is not enough for
error handling. I have got two chance.
1. I can prapare an error page and control throught IIS.
2. I can use on error resume next.
For 1. This is a general handling. I want to handle local error. Maybe i do
special thing when error occured.
For 2. I have to write alot of lines code. I have to control every line.

if I have two strings as follows :
"1,3,45,65,777,89,00
and
"8,9,67,54,89,23
The numbers represent a predefined access permission to a certain file.
I need a function to sift through the first string, and compare it to the second string. What numbers are located in the second string, which are are located in the first string need to be removed (from the second string) leaving only unmatched numbers beind.

I am using global.asax to handle my web application exceptions and have
configured it to create event log entries for errors that occur and to
display an error page advising the user to contact the helpdesk.
I have an intermittent uninitialised object error that I am not able to
reproduce in test and for which I really need the source line number.
I believe this information is contained in the PDB but am not sure if one is
created if I set the debug="true" flag in the compilation part of the
system.web section of the web.config when the application is recompiled.

We are interfacing an ASP page with a COM object. In the COM object, if there is a condition that makes it not possible to perform the requested action, an exception is raised that can be caught by the calling application.
When an exception is raised by the COM object during the processing in the ASP page, the processing seems to lock up on the ASP side on the line of the function call that raises the exception.Has anyone else ran into similar issues? If so, how can we work around them?

how i can handle errors on ASP page. Actually i want to maintain a ErrorLog in Database and want to redirect the user on an Error.asp page where i can show him the error details(i-e error #,Description etc).
I have found "With Endwith" method to handle errors but the problem is that i can only write it with a record set and it will handle only record set related errors and also i have to write With EndWith with each recordSet but i want to handle any error on page at a single place.

I have a dynamic asp page that takes input from a url. IE: parts.asp?sku=543 From there it looks up the sku in a database and outputs the part information. Currently if you put in an invalid sku that is not in my database, you just get a Internal server error.
Whats the correct way to give a 404? Do I just do a Response.Redirect to my 404.asp page if the recordset is empty?

I'm using a Firebird database to store user comments using my web app that I wrote in ASP. Some fields are mandatory. some are not. Whenever I leave the textareas blank, Firebird stores them as empty text. Anyhoo, the blob fields are subtyped to text 80 segments wide.
I'm using reponse.binarywrite() to output the text into text areas. If there is something in those blob fields, all goes well. But if there isn't anything in the blob fields or I leave a couple of the blob fields blank, the program crashes. So I decided that I want to check if there is something in the blob field, before binarywriting it. I tried comparing it to the string "" and checking to see if it's null but to no avail. Something about a type mismatch error. The exact error message is:
Response object, ASP 0106 (0x80020005)
An unhandled data type was encountered.
/tracking/updateproject.asp, line 314
line 314 is where I'm binarywriting the blank data.

I have an edit form for records that belong to numerous categories. Records are joined to categories with a join table in a many-to-many relationship.
When displaying a record for editing I loop through the category recordset, looping through the entire join-table recordset for each category, to tick (or not) each checkbox as it's displayed.
This seems like a costly way of populating checkboxes. Is there a more elegant solution?
