Architecture :: Accessing EXE On The Web Client?
Jun 14, 2010
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I have looked at some tutorials for using ActiveX for this, but they all seem out of date and the ones that I have been able run prompt the user with the Activex warning dialog, which I would like to avoid.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'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.

I am working on a website where when the user logs in, I select their database based on their username. Currently I have a list of all databases in the web.config and I select the Database ID from the username and then read the database string from web.config. What is the most optimal way to implement this scenario?
currently I:
- store the Database ID in the session object
- the Session object expires after like 5 minutes so i have to read the Database ID from the online database based on the username and regenerate the Session["DatabaseID"] again.
- there are some security issues with the Session ID, so I started clearing the Session in !(Page.IsPostBack) and I generate the Database string again.
Where shall I store the DatabaseID and the database connection string so I can easily reuse it once the user has logged in?

I've created 2 multi dimensional arrays (2 dimensions each), I want to feed them both into a function, and I would like the function to spit out an array or list containing both of them as arrays, so I can use them as they were before they went into the function.
The way I've done it at the moment is probably very inifficient and I'm having trouble accessing it properly.
What follows is my attempt to put the 2 arrays (attackerarmy and defenderarmy) into a new array called armyresults and adding an additional dimension to tell me if the record belongs to the attacker or defender:
[Code]....
Since I've already got the 2 arrays I want in the function, I've rather not inefficiently force them into a new array, only to try to re build them again when they come out of the function.
how to out 2 arrays of unknown size into an array of arrays for the return statement of my function, and then how I can access those individual arrays so I can easily copy them back out into their original form?

I need to make a webservice in .net (I know how this works) but then I need to get data out of a database. But my company wants to make it in a way that you can use the system with multiple databases.
So my option was make multiple abstract classes which contains the folowing code (depending on the database type, this would be a SQL database)
public abstract class AbstractDAO<T, Tid>

I'm developing a web application in asp.net using C# and need to access the command prompt of the server computer.
After accessing it I need to run a "ABC.bat" file in the server computer which is in folder "E:Test".
The absolute path of the server is "\MyServer"
PS: I need to run the ABC.bat file on the server machine as the bat file runs couple of more applications which are licensed to that server machine.

I am building a web application that needs to be able to interact with a desktop application. Essentially, what I need to be able to do is to execute an .EXE file with command line arguments on the client from the web application when a form submits. My initial thought is to develop an ActiveX control to handle this, but I have never done this before.

I've created ASP.NET pages in the past that sent emails using the .NET classes. However, I'd like to send an email from a webpage using the email software on the client computer.
My understanding is that the mailto: protocol allows for some arguments such as a subject and to address.
But I'm not sure which arguments are supported or how universal that support is. Also, are there other options that give me even greater control over the client's email software?
Ideally, I'd be able to specify more than one to address, the subject, and the email body, which the user could then review and modify before sending.

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.

We've deployed some reports from a server machine which can be accessed without any problems if you are logged onto the server itself by going to the URL of http://servername/ReportServer. However if we try and access the reports from a client machine (even if we use the same administrator Windows account) we get the Windows security window appear asking for a Username and Password to be entered in order to connect to the server. We've tried entering this but we then just get a blank screen after being re prompted a few times to enter the details.
Now I'm not sure whether this will be a Reporting Services or a Windows issue. Could it be a setting within IIS? It can't really be a user thing as the same user works on the server but not on the Client machine so it's more of a machine problem. It's as if there are some authentication settings somewhere that need to be set.
We are using SQL Server 2008 on Windows 7.

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 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)

I have a table that the user can add rows to through javascript by clicking on a "add rows button". In each row there are two columns one with a dropdown list and the other a text box. The dropdown list is populated with data through a sub on server side code.I need to be able to insert the data from each row into a table but I'm unable to do this. I clicked on my "add rows button" to add several rows and then did a test to see how many rows the table was returning on the server side and it did not include the five rows I added .. only the header row.If there is a better way to allow users to dynamically add rows to a table and then access the dynamically created table on the server then I'm all ears!

I have a button on a masterpage, which when clicked, calls a method that takes an EventHandler previously saved to the viewstate, this method is on the client page, and executes it:
protected void Save_Click(object sender, EventArgs e)
{
this.SaveButtonEvent += (EventHandler)ViewState["saveEvent"];
if (this.SaveButtonEvent != null)
{
this.SaveButtonEvent(sender, e);
}
}
This then calls a very simple method on the client page:
protected void Button2_Click(object sender, EventArgs e)
{
Label1.Text = TextBox2.Text;
}
However, the value of TextBox2 is incorrect, it is the value of the text box that was set when the page loaded (or if any other item on the pages changes it), the new value is not passed.
If I add a button to the client page, that calls the Button2_Click event directly, it get's the correct value.
Is the reason I am not getting the correct value of the text box because the Event is called from the master page?
I should add, that this button is created dynamically, and the event delegate will vary, which is why I have to set it at run time. I need a way to set the delegate on a click, and persist this until it is changed again.

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 ?

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?

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?

Javscript
var status = document.getElementById("<%= HidRowNumber.ClientID %>").value;
When I am debugin it say it HidRowNumber's Value has changed to x but when I access the value with JS it always returns ''.

I want to access one image file residing in C: of the client's machine. I know with the help of file upload control (or say input type=file), this would be easy. Due to nature of my application (Its a KIOSK application), user is not expected to select file. I am just wondering how should I implement reading file without using file upload control. I want to store this file in Images folder of server. I am beginner to WCF. Should I look towards WCF?
