ASP.NET Capturing USB Port Events In Both Windows And Linux
I need to develop a web application in asp.net which can detect a USB device and capture its
events...
For example when a person access the web page and connects the device to his machine he shld be
able to detect the device and shld be able to read or write into it.
I wrote a java program using jusb and called that in an applet..though it worked it needed lot
of client side configurations.
My requirement is that there should not be any configurations in client side and things shld
work smoothly.
I know some one had done this in asp and javascript. but i don't know how its done.
I have succesfully captured the users login detail, but I now have a new problem I have assigned the login to a Session Variable, however when I come to use the string stored in the variable it excludes the which seperates the domain from the user name, it should be :DOMAINUSERNAME , but I am getting DOMAINUSERNAME which really is a pain. Anybody know why this is happening and how I can overcome it ?

is there a way to capture the pagename. say I am using a form with "post" method and then use request.form to get the value of variables from the previous form. is there a way to capture the name of the form that made the request? for e.g if the first form is "welcome.asp" and the second form is "Hello.asp". can i capture the form name (welcome) in the second form?
I'm having a bit of a problem trying to capture a users LAN ID from the network. Currently I have an activex component that does it for me and I use Javascript to display/capture. Which was fine prior to the DDA guidelines. Now I need to find a way to do so without using JavaScript.
The first thing I tried was to use the Servervariables available but unfortunatly our servers use annonymous authentication, so I can't use that method. I've even tried but had no joy accessing Active Directory for the LAN ID, so I'm currently left scratching my head. Does anyone know of a way I can acheive this?
I have made a asp page that accepts some data from user and stores it in MS Access database. Now I want to identify the user who filled the form and store this information in database. About the enviornment.
the server has Windows 2000 server installed. Clients have Windows XP. Server also has Exchange 2003 installed and every client has Outlook Express installed. Every user has to login to his account inorder to use a machine. A given user can login on any machine.
How can i find the identity of the user who submitted the form? Is it possible to find out the current logged in user given the IP address of the machine? If yes, how and will there be any chances of error due to delay in replication?
I run the internal reporting system of a few dozen employees. They submit many extensive reports and if they encounter a server, SQL, or parse error they have to re-enter the information, causing great frustration.
If I can save their querystring somehow, I can fix the problem and then resubmit their input myself, saving them a great amount of frustration. Ideally, I'd like to just be able to just put a function or an include at the top of every script I'm looking to save, however, in the case of a parse-error I believe the input will halt altogether.
Can someone help me regarding Capturing Image from a Video in ASP. what I have achieved is this, I have run the video using Media Player Active-X Control and have got a button control on which I have initiated a component known as Media Processor, which saves the frame according to current position supplied in a picture format. But the problem is that it doesn't support files greater than 300 MB or so. I want to have a support of upto 2 GB files. Moreover, I have to keep in consideration the performance issues, it shouldn't get my server down. Can someone give me any idea about any component for this job, I have been able to find out only this on different locations. I have got another one that is working well in VB, but there is a problem with using in ASP. I am using Media Player just because of buffering, actually I want is kind of streaming so that the server gets minimum load. How to achieve this?

I'm trying to design a voting page. The flow as follow:
1) there is a table filled with rows (data from db) 2) each row come with a button = "vote" 3) when user click the button "vote", db will UPDATE the value(Yes/No/etc) of the row + 1
example:
1. Yes "Button" 2. No "Button" 3. etc "Button"
Since there is three button, how can the button identify which value to UPDATE in db (when the user might just click any one of it)?

I have a form that I use to submit feedback to a database. The form can be called from any number of pages and I track the page that has opened the form using the server variable, HTTP_REFERER.
A user does have the option of submitting multiple feedback messages by filling out the form multiple times and clicking submit for each (there are different categories that can be chosen on the form itself that make this obvious).
The problem is that on submissions after the first, HTTP_REFERER no longer refers to the original opener but to the feedback page (since the user returns to the feedback page) . How can I capture and keep the original HTTP_REFERER? Code:

I've got an asp app that needs to use SSL only for certain pages. Is there a way to shut off port 80 for certain pages (HTTS pages), but have it open for other pages? Can this be done in IIS? OR is this something we can do testing server variables in the asp classic vb script code? OR, do we set up another web site that has port 443 closed and only have the secure pages on that web site with port 80 closed?

What port does Enterprise Manager use to communicate with SQL?
I have to setup a point-of-sale system for a friend. He has a PC, barcode scanner, receipt printer and cashdrawer.
The receipt printer connects to the serial port. The cashdrawer connects to the printer. The barcode scanner has a keyboard wedge.
Do I need to setup the receipt printer as a windows printer? OR can I send output directly to the serial port using ASP?
The salesman told us that there is an epson escape sequence that you append to the end of the sales receipt information, which will kick the cashdrawer open, so that sounds simple enough. Just not sure on how the printer should be setup/configured so I can send the escape sequences to open the cashdrawer.

I would like to capture window close event, i.e. when user clicks "X" button of the browser, I would like to close all open dataabse connections.
Also, I would like this to apply when a user tries to close browser using File > Exit or when the user tries to type another website URL in the browser.
Is there a command within ASP similar to the Do Events command in VB6. The problem I have is that an asp page that I have written outputs many lines after extracting data from WMI. In total there are about 1000 lines generated which are displayed within the browser and saved to a database. The browser displays the correct results and they are saved into the database. But the browser only displays the results after it has completed the entire script. Is it possible to get it to output lines before continuing with the rest of the script so I can display a section at a time.
