.net - Why Cancelling 6 WebRequest Using Task.Start Takes Longer That Thread.Start
Jul 24, 2011
I have custom asynchronous WebRequest class that I am testing to find out how fast the request will be cancelled and found some odd results, that starting 6 WebRequests with TPL and cancelling them right away takes 25 sec, but when I used just regular background threads it took only 5 sec.
Update: Running them without cancelling takes with Task.Start 9 sec and Thread.Start 3 sec accordingly.

I have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?

My problem is ComboBox, with the text of the first item longer than the combo - I don't see the text from the start, I see the end of the text. I wanna see text from the start. I've tried 'SelectionStart' property set to 0, but it has nothing to do with my problem - it only sets where from text is selected.

I am creating a WPF Application that uses Fluent library.
On my computer with Windows 7, 2GB RAM and AMD Triple Core processor, after double clicking on the program icon, The Splash image shows after about 1-2 seconds.
But on my brother's old computer with Windows XP, 512MB RAM and Intel Celeron 2.0 GHz Processor (Single core), after double clicking on the program icon, First, a process called PresentationFontCache.exe runs and it uses almost 100% of CPU for some seconds. And Total time is needed for displaying the initial Splash image is almost 30 seconds (or more).
I don't want that some users have to wait 30 seconds for displaying splash image and about 7-8 seconds for loading application. (my application load process takes 7-8 seconds)

I wrote an app in Visual Studio and is about 20k+ lines, but I don't know why it takes so long to start up. I have a splash screen just to test it to see if the program is working, and it is, but I have to wait for so long for the app to actually get to the start up form. A splash screen for this app isn't ideal, but was only using a splash screen for test purposes.

I have been following the development of the .NET Task Parallel Library (TPL) with great interest since Microsoft first announced it. There is no doubt in my mind that we will eventually take advantage of TPL. What I am questioning is whether it makes sense to start taking advantage of TPL when Visual Studio 2010 and .NET 4.0 are released, or whether it makes sense to wait a while longer. Why Start Now?

Check process handle count:In Task manager, View, Select columns, mark Handle Count to the view.(The process when loaded has about 333 handles)
Operation:The new thread is set equal to an existing thread, then the existing thread is started and aborted. How does one restore the old handle count? Why do the handles increase by a random number and do not revert?
How can Idisposable/CloseHandle/or GC.collect, Finalize() work in this situation? I'm trying to return the handles to their original count, 333, when I start a new thread it adds 4,5, or 6 handles per new thread(even if the thread is aborted and set to nothing).

I'm using Process.Start to start an external command line application and using the StartInfo.Arguments method to send parameters to the application. I imagine I'll need to use a loop... but I can't figure out exactly how yet.I need to send anywhere from 1 - an infinite number of files names to this application. Each file has to be sent one after the other. So once the first one is done, I need to loop back around and past the second one.I can probably use the Directory.GetFiles method to get all of the files, but I don't know how to assign them.

Here's what I currently have:

I've commented out various things to limit it to specifically this command (example, I can swap mklink out with notepad and it works fine). The command runs fine from a DOS window, but can't be found when I use it this way. I also tried using the SHELL command just to test and I get the same results. No idea why it can't be found, as like I said it executes from the command prompt just fine.

i am trying to create a module that will start a thread to go do something. once the "something" is done i want to notify the calling form that the event is complete. i left out the thread stuff since its not relevant to the question. the following code would work fine in VB6, but .net sees it as an error because FRM does not have a FRM.done, "DoSomething" would could called by multiple forms [Code]

I am confused with the terms Build ,rebuild ,start , start without debugging in VS.NET.After writing the code what actually we want to do .We have to run directly by pressing F5 key or we have to build the solution .Usually i tried to run the application after coding and if shows any any errors i will fix that and run again .I never used build or rebuild thing .What exactly meant by building the solution .What is meant by rebuild and start without debugging.

I'm getting a really strange error. I have a program that needs to run a thread on startup, and for some reason when I do myThread.Start() in Form1() it will crash with "program is not working" (But only on Windows Server, not on my local machine!). However, if I put the same code under button1_Start() it works no problem. What gives?
EDIT A little extra information: In my thread I have a line of code that uses invoke
Invoke(new Action(() => richTextBox1.AppendText(string.Format("Updating {0}..
", DateTime.Now))));
And for some reason the crashing goes away after I make the thread sleep for 2 seconds before it starts executing. Am I using the right method to execute code on the app startup?

I know that to start a program at startup, we should add this subkey
"C:Program Files<myprogram's path><nameoftheprog>.exe"
to
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun
Alright!
But the problem is when my program has to delete a certain file in C:/ at startup, it just can't because it's not ran as administrator!
