I'm trying to do some multi-threading in my asp.net web site. But I'm having trouble getting my child thread to interact with my main thread. In the following very simple example I would expect that, 3 seconds after clicking the button, the "Hello World" text would be displayed on my page and on my label. Instead, after a few seconds, I get the following error in a pop-up box "WebDev.WebServer20.exe has stopped working - Windows is checking for a solution to the problem.". I am running Visual Web Developer 2010 Express. If you know why I'm getting this error and if you know how to fix the problem respond.
I'm a completly noob in Multi-Threading c# web pages... and i'm taking the first steps... I have one web page that create one new thread for each image to load. Each thread only read the external image and save it to local server. I have for example pages that have 25 images... that page loads but it launchs 25 thread (1 for each image).
The code:
[Code]....
I assumed that when a thread finish it's job it will automaticaly be killed, is it that way ?? I'm asking because, when i try this code on the server, after some navegation and multiple images loaded the IIS goes down and the page return "Service Unavailable" error :( To solved it i need to restart the IIS Application Pool... For those that have experience in multi-threading web pages how can i kill this threads ? Aren't they suposed to be killed when their job is finish ? ? Do you know a good tutorial or article for begginers ???
I have a .NET 4.0 console application that does a lot of reads from SQL Server 2008 using the OleDbDataAdapter object.I tried to improve performance by spreading the processing logic across four threads using Visual Studio 2010's Task Parallel Library. Sadly the multi-threaded version is three times slower than the original. Using VS2010's performance tools, I found thousands of thread contentions caused by the method OleDbDataAdapter.Fill() which populates a DataSet.This is puzzling as there are no static classes or variables involved that would result in the OleDbDataAdapter being shared by my threads. Also, four simultaneous connections just can't cause a hold up at the database level, right? The default connection pool size should be much larger than this.
Our current application is working fine but when you try to misbehave like we found out that When login with same user in multiple tab with different organization(there is a organization dropdown in the master page which sets the cookie whenever it is changed.) in tab one it is org 1 and tab 2 it is org2 , cookie has the later org 2 in it but when we go back in tab1(which had org1) and save the record org 2 will be saved with the record So can some one share some sort of a checklist with us which address these types of problem.
I am building a website using Asp.net with C# and back end support is SQL server.How to add multilingual support to it?Like in google or facebook there are various link button for various languages?I want to implement the same thing.
I've been all around the net for weeks now trying to figure out the best way to set up a Multi-tenant website (building a web app that multiple companies and their employees will use). As far as a database goes, I am interested in using one database with a copied set of tables for each company. As far as managing the login and security in MVC2 I am lost with the myriad of examples (mostly old and not MVC) that I have seen. So ideally my app would allow a company rep to register their company and then be able to add their own employees to the site. Then all employees could login and be securely associated with their own company's tables (table names would be appended with their AccountID).
I'm not sure if this would be handled using routing or session variables or what the more ideal and up to date methods might be. Like others who have discussed this issue, it seems like this should be a much more fleshed out solution as it is becoming a more common use on the internet. I'm even willing to simplify the database down to one set of tables that stores an AccountID in each row if needed.
I created a website with a single project solution. Each web page consists of C# code in a script block along with the markup. In order to make the website work with many languages, now realize that I will need to have the code for each page reside in separate code-behind files that can be combined with the markup in various languages. I assume this means that I will need a solution with a common project of code-behind files that is merged with a project of markup files for each language in order to create websites for host servers in the various countries. After I separate the code into code-behind files from the markup for each web page, I will need to know how to organize the solution for debugging and building each website and where to place each file.
How i develop multi language website in asp.net for this what steps i need if i already have sqlserver db,design template, requirements stuff and application flow
I want to build multi-language website in asp.net 2008 and asp.net 2010. So, which process is better for building application? Using either Local and Global Resource or New Folder to make separate according to language?
Application performance should be good and also easy manageable.
I have downloaded and reviewed this tutorial [URL] several times. It seems simple enough however the app_GlobalResource file is not working... so here it is.
I downloaded the sample project c# version, the website run nicely except for the global part. When I change the language in IE8 it doesn't change on the page. What is missing, is there something in IE 8 that needs to be turned on or off? I have Win7x64, VS08, IIS running asp 2.0 and IE8.
When I am inside VS08 and use the expressions property the app_GlobalResource link is there (the default) but doesn't switch between the languages.
i developing multi language website using Master pages Page_Load i set the Text property of Button Control from Resource file
like this
Button1.Text = GetLocalResourceObject("Button1") then in the button click event i cnage the text of the Button control Button1.Text = GetLocalResourceObject("Button1_new") but the text doesn't change and no error messgae what is the problem how to solve this
i want to develope an asp.net website which support multi language like french ,english, german how to do this with out any hard code also user must not b aware of how the site is changing it language he just click on country flag and the site language change to that country national language
We have a simple ASP.NET app that uses the ASP.NET SqlMembershipProvider and all is great.
We want to create a second app on the same server, also use the SqlMembershipProvider, but a different "applicationName" so that the user accounts between the two apps are kept separate.
It looks like this would be possible by making the two different app domains (ie they each have their own web.config), but I'm hoping to just put them in different directories so I don't have 3 web.configs (one for each app, and the main one) that all have to be kept synchronized. So what I'm after is:
/web.config /APP1 (uses membership provider in /web.config, with userlist A) /APP2 (uses membership provider in /web.config, with userlist B)
It looks simple to define multiple membership providers that use a different 'applicationName' value.
But how do you tell the system.web.authentication node which membership provider to use?
MSDN says that MemoryCache's instance members are not thread safe. (http://msdn.microsoft.com/en-us/library/system.runtime.caching.memorycache(VS.100).aspx)
Does that mean every time I call Get() or Add() in a action method I have to wrap it with a lock?
I want to use my functions in DAL asynchronously by executing them in a separate thread. The issue in all this is suppose I have a function DAL.GetProducts() which returns a DataTable. If I execute this function in a separate thread, when it is completed how do I get the returned DataTable from this thread and bind it to my UI?
I'm trying to get threading to work in ASP.NET but for some reason it keeps crashing my local server, and simply does not work at all when uploaded online. Here's the code:
protected void testThread() { for (int i = 0; i < 10; i++)
This may seem like a really simple question, but can I use the System.Threading namespace in ASP.NET web forms? I have a web page which uses HTTP GET/POST to gather page customisations (title, subtitle, etc.) from the user and numerical input which is passed to a ASMX web service. Currently they work sequentially, the customisation first followed by numerical processing. So can I use threading to do this?
In my ASP.NET website, I am having a function which has to be automatically performed once every 2-3 mins on its own, i.e. without user intervention. This function contains database access.
Can I use threading to perform this process in background?
If Yes, How can I use that?
Edit
Also I am not looking for a solution which includes windows service because I am using shared hosting. So I dont have all the rights to access the host computer.
I have a Main page containing links to five other pages. each page has a button which does some job using Thread. Problem is when i open a window from main page and click the button, The Process starts but if now i want to open another page from main window it doesn't load untill that previous page loads fully(when thread ends). I am not using any session variable on my page.
I m getting the error System.Threading.ThreadAbortException while exporting datatable to CSV. But export to CSV is completed sucessfully.Here is my Code:
