Create Fat Client (RIA) With HTML - Controlled Environment?
Oct 25, 2010
I realize that this question can start a discussion but that's really not my intention. We've created a Flex Application to take tests from candidates. The advantage of the Flex Application is that all state can be stored in the application running in the browser of the client. Things like time limits, navigation, scoring, ... can all be handled within the application without us having to worry about a back button for instance. Even running the app offline with Adobe Air isn't that hard.My question now is if such an application could easily be made with HTML, Javascript, Ajax, ... ? The reason I'm asking is because an application in HTML would be much easier to distribute on Mobile devices for instance. Also, our domain model for instance is mostly implemented in AS3 (Flex) so using it along the server side means porting it to C#.NET. (with two codebases as a result).

I tried the below code for getting clinent ip address. Request.UserHostAddress; or
Request.ServerVariables["REMOTE_ADDR"]; or
Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
If the request coming from IE it will work file, but in the case of Mozilla Firefox it shows the proxy ip address. I am getting the sam ip addres from different machine if the request from mozilla firefox.

I have an intranet ASP.NET web application in which I need to get the IP of the client's machine. I do this vis the following code:
HttpContext.Current.Request.ServerVariables.Item("REMOTE_HOST")
It used to work when my ASP.NET site was only hosted on a single server. However once we got the load balancer installed and migrated our apps to a web farm, the code above returns the IP of the Load Balancer device and not of the client anymore.
I am working with the networking folks to determine what can be configured differently with the load balancer, but in the meantime I was wondering if there was another way I could get the client's IP other than using that IIS Server Variable?

We have had complaints of users losing data that they entered in textboxes in our ASP.NET 2.0 web application. Users are authenticated using Web Single Sign On method. My boss would like to save the client data in a file on their local disk in case they lose connectivity. I know this is not allowed with the default security of ASP.NET.
Would it be possible to programmatically change the ACL permissions for the NETWORK SERVICE account to access the isolated storage folder on the logged in user's local disk? Is there a better way to achieve this goal of persisting user data to a file?

i am currently developing an asp.net mvc 2 web application and i would like to create new foldersprogrammatically with access rights, in order to enable loged on users upload their image files.My question has to do with how to assign write access using Directory.CreateDirectory function and assigning DirectorySecurity rules (meaning for which user should i enable user rights, etc...). Note that the hosting envirnoment uses IIS 7.

do you think it would be difficult to write a framework where mvc compares last html it output to the current html we want to output, and instead of sending the entire html, figure out what has changed and generate js code that will do the updating as compared to previous html? (presuming nothing was manually changed on the client using js).

An abstract high level idea of where to begin as I am totally clueless at this point.
Background:
I am setting up an intranet site (ASP .NET) where users from our local user group (who are also added in our user table) will have access to web applications they are given access to. Right now I am developing from my PC and using SQL Server 2005 Express as the database, but the final site will be hosted on an application server with IIS 6.0 and the database on an instance of SQL Server 2005. I am a .NET newbie and it's a daunting task, but the experience is worth a million dollars.
Details:
We are using Windows Athentication for our intranet site. Therefore I am not using ASP .NET's membership data sources. Rather all the user information will be stored in two tables tblEmployee (all employees in my company) and tblUser (all users of the intranet site).
tblEmployee has fields - EmployeeID, FirstName, LastName, CostCentre, Role, ManagerName, UserID
tblUser has fields - EmoployeeID, UserID, ApplicationID, AccessLevel, AddedBy, DateAdded
(I have set up these tables and I can change them any time).
What I need to accomplish - When an user goes to the intranet site, I can get his/her domain username. I need to check if this user exists in tblUser (domain username is same as UserID in tblUser). If user exists, we display all the applications he/she has access to, else display a "no access" page.
Specific questions:
What are some of the things I need to "learn"? (as I said before, I am a .NET newbie, but a fast learner too) I need to use URLAuthorizationModule for validating a page request. How do I hide the username from the URL? I was thinking along the lines of using a session ID... but then how do I know who the user is? I am sure these is a way to encrypt the UserID, just can't find it.

We've got a client app which connects using TCP to a server. Additionally, the client app makes use of .NET remoting to talk to another piece of locally running code.
I'm tasked with creating a "Client Simulator" to do some testing, where we'd need to have 100's of clients connected simultaneously to the server. Ideally, this would work out great if I were to run each client in it's own space, such as a VM, but this is not logistically feasible.
how to handle this? Is there a tool that could do something like this? Or some sort-of .NET concept I could use?

I am working on an ASP.NET web application, we are a small team (4 students) and we do not have access to a dedicated server to host the database instance. So for this web application we decided just to put the database file in the App_Data folder.
The problem is that our project is source controled on TFS, so every time you open the solution and try to launch the web application, we get an expcetion saying that database is read-only. That is logical because the databse file is not automatically checked-out.

A static web page (html) uses XHR calls to an ASP.NET page The .NET page retrieves information from a remote server using web services The .NET page returns an HTML "snippet" that is inserted into the static HTML page I'm getting hung up on how to deal with the HTML snippet generation on the .NET (2.0) page. I've thought about something like this in a generic .ashx page:
public void ProcessRequest (HttpContext context)
{
context.Response.Write("<ul>");
//assume "people" is a list of data coming from the external web service
foreach (string person in people)
{
context.Response.Write("<li>" + person + "</li>");
}
context.Response.Write("</ul>");
}
It just seems a big "ugly". Has anyone done this another - and possibly more efficient/elegant - way?

saving a static HTML page on the client, so that I can then upload it back to the server? I'm building a Gantt style page, then allowing the user to "draw" on it using VML (This will change to SVG once we are off IE6). I need to be able to save the page (including the VML) to temp and then upload it back to the server as a static HTML file.

I'm trying to get a very simple client side validation example to work in ASP.NET MVC 2. I'm using data annotations to set a required property "Surname". When I use the Html.ValidationMessageFor(x => x.Surname) the correct client side validation script is written to the page. But when I use Html.ValidationMessage("Surname") the client side validation is not rendered out until after the page has been posted. Client side validation only starts working after a form post! I can see that the script is updated in the page after a form post. There appears to be a bug in Html.ValidationMessage()?

I have the following client side code in .aspx page within a datalist itemtemplate that takes questions from the database like this:
[Code]....
The output is like:
1) What is your age group?
- Option 1
- Option 2
- Option 3
- Option 4
The ID's of the radio buttons are dynamic ("Q" & QuestionID). If there is no answer to a question then the GetVisible function returns false and the containing panel is hidden.
I have been trying to get rid of the html and replace these with asp:radiobuttons but it is not possible to set id's from databinding.. only simply. I was trying something like:
<asp:RadioButton ID="Q<%#Eval("ID")%>" runat="server" Visible='<%#GetVisible(Eval("OptionA").Tostring())%>'
Text='<%#Server.HtmlEncode(Eval("OptionA").ToString())%>' />
Here is the function that provides data:
[Code]....
but I'm finding it impossible to work with the html controls, i.e get their .text value from codebehind, or adding events!
better way to replace the html with suitable asp.net web controls or from the codebehind and output it. Or point me in the right direction?

I am developing a web page where a user will submit some "Comments" on a form. When they click the submit button, I fire off some javascript that captures their current GPS location, which I store in a visible Text Box (for testing purposes). If the user is updating from a device that doesn't support gps, I add text to my textbox that says "Device does not support GPS".
When I get to the server, using a device that doesn't support GPS, that text comes through just fine. When I use my iPhone, I see the GPS Coords in my textbox, but that textbox value doesn't make it to the server.I'm thinking that there is a 2-3 second delay from the time that the button is clicked to the time that the java finishes retrieving the GPS. So the textbox text isn't set fast enough.I'm wanting to prevent a postback for 3 seconds (for example) to give the javascript time to update the textbox.
