Architecture :: Web Application For Dealing With Client Resources?
Aug 13, 2010
I am planning to convert desktop application which has to deal with lots of client resources like printer, Id scanner(driver license,passport & business card etc.), webcam etc.Now accessing client resources like files, scanners and webcam everything has to be done through client side scripting which is really pain. Due to nature of this product, I have to create image on client PC and extract information from it. (This is also pain in Vista and Windows 7 due to security permissions and all that stuff).
My ideal design would be making managed dll which takes care of dealing with images, printers, webcam (I have to apply pan, tilt and zoom), id-scanners. This is kind of component. And GUI would be web based Asp.net which simply calls the functions of managed dll. If the end-user is opening application on new computer, then it will ask just like flash or silverlight that you have to install component locally for the first time.Points which I worry: 1. If it logically correct or sounds stupid? 2. How to install managed dll at end-user's PC (C:/program files) and use it from asp.net code behind page.
My application is intranet application.so avoid stupid assumptions about privacy and ohhooo you want to access files from my PC and all those stuff. (end-user would never mind in giving credit card to restaurnt waiter who could do anything with it behind counter but allowing web application to access file which is created by application is privacy issue)

Can some one inform me whether I need to replicate the same set of entities in the client which are similar to that of the ones in the server? I have planned to start a proj with service functions as wcf services and in turn they are getting referred in silverlight client application.
Incase if i need to consider casting to or back from the return value lists of service methods in the server, should i be creating entity class in the client application as well? Or is there a work around? Something like exposing the entities from the server just as the services functions?

I am working on an application where it stores information that different clients will be using. I need to figure out how to show the current client logged in only what they have posted to the application and not everything that has been posted to the application. Client 1 logs in and sees what they have posted; client 2 loggs in and sees what they have posted.....etc. Can anyone shed some light on this for me?

My application creates some images at client machine using client side scripting VBScript. I want to store those images in database, so I need some way to bring those images to server without any interaction with users (means I can not use the file upload control).Along with this, application would also like to use the printer attached to client's machine (it could be her network printer), without showing printer dialog.
Basically I need to create some client piece, dll which will handle the scanning, printing and uploading images from client pc to server and web application will interact with this dll.How could I achieve this? I explored a lot on internet. many articles suggest that use activex control, but how in c#?
I am not asking any spoonfeeding. Please show me correct article or small working sample or example, I would figure out the rest.

I'm going to create my own project, and i have some difficulties with technology selection. I will have client application(windows forms) and web service. Data exchange between clients will be only by using this web service. Data will be like image stream,so I don't know which technology to use. I started to look at WCF, but i don't know a lot about it.

We have a website on IIS7 using ASP.NET Routing that seems as though it might be running out of resources.It just hangs after a few days, there is no error message or apparent crash.
We are making sure every .Open command is matched by a .Close command on the database connection.
We are doing the same with file Open/Close but there are very few of those.

If a user clicked on a button, which runs a one minute process that MUST stay connected to the file (through the use of FileStream) for writing purpose, and he/she accidentally closed the browser. Currently, when that happens, if the user clicks on the button again, it will return an exception saying that the file is still being used. The part where I write to the file, the code for that is in a class library, which has a destructor (or finalizer, whichever), which calls a Dispose() method. It would usually take about 20 seconds before the file is free again to be used, but is there a way to make it quicker?
I'm thinking the way I'm designing my web app is not the conventional way. How do most people avoid this situation (ie. accidentally closing browser) where a file/resources are not freed up? Do they write into a SQL server instead of a flat file?

Reposting my unanswered in technet.microsoft question?
MSDN "ASP.NET Delegation" article tells:
1) "When you configure to use a particular account as the process identity, ASP.NET attempts to delegate that account. If it is a local account that is identical (including password) to a local account on a remote machine, delegation is possible. If such an account does not exist on the remote machine, to the network it appears as the Windows anonymous account (NT AUTHORITYANONYMOUS LOGON). In addition, delegation is also possible if the account is a domain account that has access to the remote machine, in which case it uses the domain network identity of that account."
The same frequently repeated story as in case of manually/interactively accessing remote computer (server resource) in workgroup - it is necessary to create local account with the same username, the same password. But why?
If a workgroup Windows client process cannot access resources on server machine without having duplicate of such (local) account on target machine already pre-created,does it mean that client (process, machine, or user) can access server resources only by/after having logged (opening logon session) into server machine? Or, how to understand that such access is impossible without having corresponding duplicate local account on server machine?
The same MSDN "ASP.NET Delegation" article tells:
"NetworkService account. It behaves the same as the System account. This account possesses the network credentials associated with the machine account (domainnamemachinename) in the domain of which it is a member"
Does not any Windows have accounts ((NT AUTHORITYNETWORK SERVICE)? as well as many other common pre-built accounts? Why are they installed (before any joining to domain) but cannot be used for remote network access and client identification ? And what is identity used when the process from workgroup Windows under identity ((NT AUTHORITYNETWORK SERVICE) accesses a remote server?
My related questions:

I am looking for a way to integrate a web application with a client application that will sit on the users desktop. Our scenario looks like this user will click a link in the client server application that will launch an .ASPX and pass various parameters via a querystring. User will make form inputs on ASPX page and on that input, I need to be able to execute a .EXE on the client machine that will refresh the window in the client server application.
I have looked at some tutorials for using ActiveX for this, but they all seem out of date and the ones that I have been able run prompt the user with the Activex warning dialog, which I would like to avoid.

I need to develop an application, which will get records (orders) from one application and process them. The updates to this records (order updates) will be sent back to the source application for end customer reference. I'm planning to achieve this data synchronization at the database level using triggers and stored procedures to insert database between the 2 databases.
But, the issue is I have to deploy this application in 3 different customer sites and I have to change the database names (cannot use the same database name) in each deployment manually. Because of this deployment issue, I was thinking of handling this within the asp.net application where I can store the db name in the database and then build the query within the application, but I dont want to do it as building queries like that doesnt look very professional.

We need the a solution for our ASP.NET website. in which a user needs to activate his machine and next time if he visits the site then we need to check the machine is activated or not. if the machine is activated then we want to redirect the user on different page.
Is there any way by which we can get the client machine MAC address and store it our database?
I have found some solution in which this can be done but it works on on IE and some ActiveX setting needs to be done.We want this should work on atleast IE and FireFox.

What is the best approach to update the data in these table. note that the whole application is not changing but only the data in it changing, no change to structur of the database or table.

I have recently upgraded to VS 2010 and converted my web site into a web application. Now, when I attempt to build, I receive the error:
Resource name '<name>.Resources.resources' cannot be used more than once.
There is no page name or anything, and I have completely exhausted all that Google has to offer.

I have been using properties and have idea that using properties with private fields we can implement validations and buisness rules in them.
But I am just thinking asp.net client side validation controls provide good strength and they provide good user experience as well. They can be used for any type of validation (using regular expression) on client side and their re-use is possible on server side. When validation controls are a must and they are powerful; is making properties not just wastage of time ?
Is there still some use of properties ?

This is not a programming question per se, but rather an attempt to find the adequate technology to use for my objective. My mandate is to build an ASP.NET Web Application. However, on certain pages, some client-side information needs to be fetched by interacting with hardware on the client's computer, for example a barcode reader or an RFID tag reader. My first reflex was to think "ActiveX" controls with, perhaps, some AJAX coding to fetch the required values from said control. However, I am not sure if I am up to date with the latest tech trends. The solution I'm looking for will let me design a user control that plugs into my ASP.NET Web Application, lets me interact with client-side hardware, and can be automatically downloaded from the Web Application itself (I can't predict which computers will access my Web Application). Which technology(ies) should I go for?

I have a block of XML in a database which is easy enough to pull out using ASP.NET MVC, however I would like to access and modify the XML in an way more consistent with class instances. Is there a way to get the MVC (or any other model) to generate a data access (or perhaps Entity) class set from the DB-stored XML?If the above is rather obtuse, the question could be summarised as; What method would you use to best access and modify XML stored in a database from an ASP.NET MVC application?
