Vb.NET (Visual Basic 2008/2010) : How to use a BackgroundWorker

[@chriscowman]

Thanks a lot. I've been looking for a good tutorial to show me this. I needed to monitor the clock speed of my cpu but my GUI was going all non-responsive. This is exactly what I needed :)

[@darrenlogan6438]

Hi, Forcing "Ignore cross-thread errors" is not recommended. You should update all ui controls in the report_progress event, just like you did for the progress bar. Not the best advice from a tutorial!

[@dravenadonis8952]

Pro tip: watch series on Flixzone. Me and my gf have been using it for watching all kinds of movies these days.

[@christianotto3910]

@Draven Adonis Yup, I have been using Flixzone for years myself =)

[@henriklauridsen9686]

Thank you. I enjoy they way you show how to. Hope you do many more.

[@JonahLiu]

Awesome. Best tutorial I've seen about coding, and I've seen a lot.

[@firasdaw6745]

spontaneous and straight to the point .. thank you

[@RandomGermanBrit]

Thanks a ton! Now I actually know how I can make my program download stuff! Could you also make a tutorial with the same kind of topic, just one where the backgroundworker saves the file/s to a specific location? If yes, then that would be awesome!

[@babzo1]

Another well explained tutorial .Thanks Brandon.U got d skill....

[@Doowi92]

to fix it its simple just modify your label1 text like this Me.Invoke(Sub() Label1.Text = i) like this no need to add checkforillegal...

[@bobbriggs4287]

Thanx for showing me how to perform a wait using thread sleep.

[@TonyAwad88]

Good job on this. Clean and straight forward. Cheers

[@GabrielM01]

Do you have a tutorial for the delegates? I can work for this for now with my applications, but i know crossthreading is dangerous, i would like to learn delegates aswell

[@dragoonadept]

Internet heroes, the lot of you brave, brave souls.

[@SiebeBosch]

I've got a few hundreds of tasks to run, of which I'd like 4 to run parallel each time. Any thoughts on how to do that? I guess 4 background workers should do the trick, but then again: how do I keep track of which worker has finished and can start a new task? Or would a PoolThread be a better option here?

[@GameWithBrony]

Thank you very much! You helped me with making a program simillar to Tapatalk

[@empemitheos]

great video, so much clearer than the msdn docs

[@enzanblazer]

Amazing tutorial man, very clear and easy to follow.

[@enzanblazer]

Do you have a video where you explain the delegates part?

[@romzcodie2337]

Hi sir, thank you for this wonderful tutorial, it really helps me a lot, but if you don't mind, may I ask a favor on how to apply this progressbar and backgroundworker in saving data from datagridview to ms access database. Thank you so much for any help sir. God Bless!

[@xxblinddxx]

Thanks.. just what i was looking for!

[@skateboarderboy1]

Question, I have implemented a background worker and works great. The project I am working on basically copies a the entirety of one directory to another. If a file fails to copy(ie. it is to long for the destination path) then it catches the file as an exception and write the file name and path a a text file entitled 'error log'. The background worker works in when the are no exception files caught, but if an exception is caught, the report progress of the background workers is failing to continue adding a file counter to the total progress even though I have a variable dedicated to counting the files even this cases and reported this number to the report Progress method. The background worker end prematurely in the later case, even though there is still plenty of "work" to be done. Any ideas?

[@razorramzan-inc]

Have you tried using Try, catch

[@herrjonna2007]

Amazing tutorial! These are rear, keep up the good work!

[@Tonio2110]

It seems that loops run annoyingly slower in the BackgroundWorker than in the default Thread. Is there a solution or alternative to that?

[@punksnotdead4766]

Good tutorial

[@lightningz1712]

Does backgroundworker continue to run if the form is closed?

[@Atri48]

How did you got that title sequence?

[@Camixcs13]

Thanks Great Tutorial :D It helped me with my "Email Sender" Application :)

[@leocfox]

i want to show a picture of a loading.gif with the background worker. rather than a progress bar.. can you help me with this please?

[@VidGaming]

Is the count milliseconds?

[@Atri48]

Do you have windows 8??

[@polasanderson6353]

the code is good but if you use it for scraper to scrape links so it starts freezing a a little bit. Now i need to know how to stop the backgroundworker cuz the cancelasyn() is not working at all Thank you.

[@LiableOne5]

[@gtag174]

[@femtozz]

very very useful ... thank you

[@Hackerzpwned]

Nice tut :)

[@ashraf.mohamed]

You are a genius. thank you very much :)

[@buddyroach]

[@CorruptKrown333]

Run it on Form_Load.

[@LiableOne5]

How do you cancel / stop the background worker

[@mattkingz]

Thank you for the tutorial! c:

[@eduardocatoc8505]

thank you so much, sir!

[@DoubleDYouTube]

I tried to make a file copier or a downloader and progressbar doesn't work! Why?

[@DoubleDYouTube]

@@Personal-rc7cy Uh... Sure... Let me just dig up my 9 year old Visual Basic projects...

[@raygun2092]

thnx

[@LedinukasTV]

Very nice theme. Can you send me link of your theme? (buttons, progressbars) Please. ;P I subed.

[@polasanderson6353]

Still freezing and even does not stop

[@peterschiller2451]

Instead using backgroundworker, you could use the Async method. Private Async Sub Button.clicked bla bla your code await task.delay(200) end sub

this is pathetic, urgh me.invoke(sub() me.label.text = "fucking few words to do this") delegating is hardly fucking hard is it?

[@ryanthomas1902]

I have done the check for illegal cross thread calls but am still getting the error... any ideas?
