We are using static hashtable in webservice for sharing common data among different users. Is it safe? Is there any better way?
View 1 RepliesI have defined a public static HashTable. It stores data for a few seconds of runtime, and then data disappears, and then the HashTable becomes null.What is the issue and how do I solve it?
View 1 RepliesWhat is the best method/technology to sharing the same data access layer between WPF, Silverlight, and ASP.NET? I am using ADO.NET Entity framework, and was thinking of a creating a DAL using the Repository pattern.Then using the RIA Services as a dummy middle man to connect Silverlight and ASP.NET. Is this a solid plan or are there other better solutions out there?

View 2 RepliesI have an asp.net application and webservices (asmx) that reside in the same application but not in the same folder of the aspx files. I aslo have a winform application that uses the webservices. I have marked the webservice methods with [WebMethod(EnableSession = true)] but I am not able to share the same session values that are on the application in the webservices. The winform application has access to the sessionID from the application and I am using the following code
Uri uri = new Uri(ServerServiceUrl);
_cookieContainer = new CookieContainer();
_cookieContainer.Add(new Cookie("ASP.NET_SessionId", SessionID, "/", uri.Host));
My question is: Is there something that I am missing or doing wrong that I cannot access the application sessioin from the webservices?

I would like to create several applications mapped with a common applicaton Users Accounts. The aim is to isolate logical parts.

I'm starting using web services in .net , I'd like to know how to achieve this:
I need to import table data into a database, currently what we do is uploading via ftp the text files, and then running a process in php in the webserver.
Could this be automated by sending those text files (or xml, or whatever format is necessary) to a webservice as an argument, and that the webservice handles the insert and validating process of the data?
I have an ASP.Net 4.0 web application which very frequently loads data from the database and does heavy calculations on it. I want to cache this loaded and prepared data in a central cache that can be accessed by every user and computer who uses the application.
Simple use-case:
User 1 accesses webpage, cache is empty, data is loaded/calculated, data is cached
User 2 accesses webpage, cache contains data, data loaded from cache
User 3 accesses webpage, cache contains data, data loaded from cache
User 1 reloads webpage, cache contains data, data loaded from cache
Cache expires
User 3 refreshes webpage, cache is empty, data is loaded/calculated, data is cached
I know that ASP.Net has a built-in cache mechanism. What I don't know is whether it can be shared between different users accessing the site on different computer at the same time. I would also like to know how the system behaves in a web farm environment.
I want to build a webservice that has to get some data as parameter from the client application. the data from the client side are records from there database. my websercie has to send then these data to a soap server through 'HttpWebRequest'. Can i get the data as Datatable? and then send as stream to the soap server? Or maybe there is a better easier ways?

View 5 Repliesvs2010, .NET 4.0I have a webmethod which I want to return a data record (for example: name, surename, address, age, zip etc)I wonder how to accomplish this. I think the solution is about creating an object which contains all the records serialized. And then the webmethod returns this serialized object. I'm not 100% sure how to accomplish this, if some of you good provide me with some tips, tutorial or link to an article explaining it, that would be great
View 1 RepliesI have spent a couple of days on this one. I have an ASP.NET website that has Linkbuttons on
the Default.aspx page.. I added a WebService to the Website because later on the WebService will
subscribe to a Provider(Feed) of News, Sports and Weather and things like that. So when a Linkbutton
on the Default.aspx page is clicked it will connect to the link in the WebService which will load the News,
Sports or Weather onto the Default.aspx web page.
The problem is I can't get the LinkButton to execute the Link in the WebService. The link will call the page up
to where you see all of the Web References. But then if you want to execute one of those references you
have to click its link and the Invoke button that will follow. My questioh is how can the link on my Default.aspx
page execute the link in the WebService. Now I changed the LinkButton into an <a href> but I still can't execute
the link in the WebServices. I always use www.Microsoft.com as the link when testing and I wasn't sure about the return type
so I put "void" for an HTTPRequest, so below is the link from the Default.aspx web page and below that is he asmx file:

For reasons I would rather not discuss, I need to create a custom authentication system for my app. I was just reviewing the system and am having some doubts if my solution is thread safe. My goal was to create a solution that would allow my app to authenticate a user one time and that users authentication info would be shared by all master pages, pages, classes, user controls, etc that are used. (But not share the same info between users) Here is my setup: PageHttpModule.cs - this is added to the web.config as a httpModule.
public class PageHttpModule : IHttpModule
{
public void Init(HttpApplication app)
{
app.AuthenticateRequest += new EventHandler(OnAuthenticateRequest);
}
public void OnAuthenticateRequest(Object s, EventArgs e)
{
CurrentUser.Initialize();
}
public void Dispose() { }
}
CurrentUser.cs
public static class CurrentUser
{
public static bool IsAuthenticated { get; private set; }
public static string Email {get; set;}
public static string RealName {get; set;
public static string UserId {get; set;}
public static void Initialize()
{
CurrentUser.AuthenticateUser();
}
Note: this is a scaled down version of my authentication code.
public static void AuthenticateUser()
{
UserAuthentication user = new UserAuthentication();
user.AuthenticateUser();
if (user.IsAuthenticated)
{
CurrentUser.IsAuthenticated = true;
CurrentUser.UserId = user.UserId;
CurrentUser.Email = user.Email;
CurrentUser.RealName = user.RealName;
}
}
}
UserAuthentication.cs
public class UserAuthentication
{
public string Email { get; set; }
public string RealName { get; set; }
public string UserId { get; set; }
public bool IsAuthenticated { get; private set; }
public UserAuthentication()
{
IsAuthenticated = false;
Email = String.Empty;
RealName = String.Empty;
UserId = String.Empty;
}
public void AuthenticateUser()
{
//do some logic here.. if the user is ok then
IsAuthenticated = true
Email = address from db
UserId = userid from db;
Realname = name from db;
}
}
I have tested between 3 different browsers and it seems to work fine, but I am still learning and don't want to make a huge mistake. If my logic is totally wrong, then how should I do it so I dont have to put user lookups on every page directly?
I am looking for opinions and best coding practices.I need to get info from a database with a query such as SELECT this, that FROM MyDB (returning 2 fields). Would it be wrong to use a hashtable for temporary storage?Is there a better way to accomplish the same thing? What about if I am returning more than 2 fields, would it be best to step up to a DataSet or something?
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
GetData();
