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 ???
We are creating a composite server control. It will have few other controls. I am confused where exactly to write the code ie in which event. Is page life cycle and control life cycle follow the same event order?
Why class name and method name dropdown list is not similiar to vb in c# code behind.
Say for example I am getting all the events for page in vb.net, But I am not getting same as vb.net in c# while I am trying write code for page life cycle events in c#.
Apparently I am not familiar with the Life Cycle of a page in ASP.NET. This became apparent when I wanted to dispose of a Session variable after I left the page. I did what made the most sense:What I didn't know is that this would be called when I go from AND to the page. What I am wanting to do is dispose of that Session variable whenever the user leaves the page.
I am writing a web application that takes in session variables from the user and when the user comes back to the page the form elements are automatically filled with the users entery. So I tried using the page_load event to check to see if the session object was equal to null. But then when I rerun the application the form elements are filled in with the previous entery. Does this mean that if a user logs into the system and has a session withing the lifetime of a previous session that the form elements will be filled in with the previous data?
I'm trying to better understand the life cycle of an object in the .Net framework. My companies Intranet has some custom classes that were written by a vendor that I'm trying to make some modifications to. Specifically I want to set some variables & hashtables to null when use of the object is done. For now I have this in the dispose event.
Is there any info you can point to that would be good reading on the life cycle of an object in the .Net framework? I.e. what order do the events fire in? OnInit, Initialize, finalize Dispose, etc. I have the ASP.net page lifecycle but I'm not looking for that.
I have user controls with buttons that have hooked events. Controls with events need to be initialized in Page_Load or earlier.
I wish to spawn these user controls dynamically by clicking an Add button.
It is important to remember that events, such as click events, are not fired until just before Page_LoadComplete.
Broken Solution A:
[code]...
Result: Everything works great, except the button within the added user control is inert.
The conundrum is: I need controls to spawned by a button click, which means I need to put my Controls.Add(...) code in Page_LoadComplete. Inversely, I need the controls being added to have working events, which means the Controls.Add(...) code need to be in Page_Load. I have a perfect dichotomy.
I want to find out the page life cycle of a page contains: master page, content page, user controls. I have seem a guru posted the whole events sequence of such a page here in this forum but can't not find it again. give me the link to that post or provide answer directly?
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 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.
1) I know there are lots of web sites that describe in what order events are called during the Asp.Net page life-cycle. But is there also a tool, perhaps Reflector, that would enable me to figure out by myself in what order are ALL the page's events and their event handlers called during the page's life cycle? 2) Would you say that trying to figure out exactly what is going on under the hood is a good idea or a waste of time? To clarify - I'd like to figure out exactly what is going on when a control tree is build - thus all the method calls, all the events called etc needed for control tree to be build ( I imagine there are hundreds or perhaps thousands lines of code written just for building a control tree).
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.
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?
