Web Forms :: At Initial Page Load Start A Thread

Jun 17, 2010

I have an application that initially display 4 grid views at page load. This process takes 50-60 seconds and I would like to change the process to display the web page, show message like "Data being loaded, please wait..." and then spin off a thread that fills the various grid view. When this is done I would programatically like to do a post back to show the result. Not sure if this is possible? I tried something like this:

How To Start A New Thread To Query A Database While Web Application Continues Running

Feb 11, 2011

I want to start a new thread to query a database while my web application continues running. I was under the impression that by using threads I can run the querying process independently while the normal web application page cycle carries on, but I could be wrong.

public class DbAsyncQuery
{
Dictionary<string, object> serviceResults = new Dictionary<string, object>();
public void UpdateBillingDB()
{
QueryAllServices();
foreach (KeyValuePair<string, object> p in serviceResults)
{
IEnumerable results = (IEnumerable)p.Value;
IEnumerable<object> sessions = results.Cast<object>();
DbUtil.MakeBillingDBEntry(sessions, p.Key);
}
}
public static string[] servicesToQuery = new string[] // Must go in config file ultimately
{
"xxx.x.xxx.xx"
};
public delegate void Worker();
private Thread worker;
public void InitializeThread(Worker wrk)
{
worker = new Thread(new ThreadStart(wrk));
worker.Start();
}
public void InitializeQuery()
{
Worker worker = QueryAllServices;
InitializeThread(worker);
}
private void QueryAllServices()
{
Dictionary<string, DateTime> lastEntries = DbUtil.GetLastEntries();
foreach (string ip in servicesToQuery)
{
string fullServicePath =
"http://" + ip + ":800/MyWebService.asmx";
//object[] lastEntry = new object[] { lastEntries[ip] };
object[] lastEntry = new object[] { new DateTime(2011, 1, 1, 0, 0, 0) };
object obj = WebServiceHandler.CallWebService
(fullServicePath, "MyWebService", "GetBillingDBEntries", lastEntry);
serviceResults.Add(ip, obj);
}
}
}

It seems to basically stall and wait to finish the query before loading the page (which can be thousands of rows, so it takes awhile). I put this in the following section of Global.asax:

protected void Application_Start(object sender, EventArgs e)
{
DbAsyncQuery query = new DbAsyncQuery();
query.UpdateBillingDB();
}

This is one of my first web pages, and I'm new to threading. I understand there is a difference between creating your own thread and using the ThreadPool. In this method, I am using my own thread, I think. Not sure if that's the best way. The querying process can be completely independent, and its only going to occur on scheduled intervals (every 8 hours or so). The user doesn't need to have up to the minute data, so it can take awhile. I just don't want the site to wait for it to finish, if that's possible.

Start Batch Job From IIS / Start Exe File With System.Diagnostics.Process.Start With Another Account Is Disabled?

Oct 28, 2010

What is the right approach when users (authenticated domain admins) should be able to start batch jobs (usually exe files) from an IIS (7.x) aspx (c#) page? This is an intranet site. The batch jobs have to run on the web server as Domain Admins. The website pool is executed by network service or some similar restricted account in AD.

Approaches I can think of (and their disadvantages):
1. Start exe file with System.Diagnostics.Process.Start with another account. This feature is disabled in IIS 7.x, how do I allow it?

2. Create a sheduled task and call scheduled task-api. This unmanaged dll is giving VS compiler warnings because it's unsafe to call from managed code.

3. I suppose there's a better approach, because the previous suggestions doesn't appear safe or robust.

Architecture :: How Can Thread Update A Variable Shared With The Main Thread

Nov 24, 2010

I'm new to threading and have used it successfully, but limited. I can spawn a thread and have the main thread reference variables in the spawned thread, but I don't know how to allow the spawned thread to reference (and update) variables in the main thread.

Any example threading code I've seen on the web appears to be WAY more complicated than what I do, so I am unable to understand or integrate into my code.

Here is a quick example of how I use threading:

What Are The Differences Between Currently Executing .NET Thread And Win32 Thread

Mar 24, 2010

I am reading the Asp.net security documentation on msdn.I come across these tow terms and get really confused.

# WindowsIdentity = WindowsIdentity.GetCurrent()

which returns the identity of the security context of the currently executing Win32 thread.

# Thread = Thread.CurrentPrincipal

which returns the principal of the currently executing .NET thread which rides on top of the Win32 thread.

C# - Lock Thread.sleep Not Working With .NET Thread?

Jun 25, 2010

I have a password page and when someone enters an incorrect password I want to simply foil a brute force attack by having

bool isGoodPassword = (password == expected_password);

lock (this)
{
if (!isGoodPassword)
Thread.Sleep(2000);
}
I would expect that this would allow all correct passwords without stalling, but if one user enters a bad password another successful password from a different user would also be blocked. However, the lock doesn't seem to lock across ASP.NET threads.

I am trying to register the route collection in .net based on each session. The code I have works fine, you goto website/username and it loads the correct sub pages, but you have to restart the application to goto website/username2 to load those sub pages. But when the application is restarted the second one works, but then not the first one. Is there some way to create a different route collection per session not per application using system.web.routing.
