BackgroundWorke r vs. Asynch delegate method and BeginInvoke thread

Hello,

I need to create a background thread and two (or more) options are available
to me:

1. BackgroundWorke r
2. Asynch delegate method and BeginInvoke

What are the differences between them in performance, complexity etc.

Thanks,
EitanB

BackgroundWorke r is easier. Unless you have some specific reason to not use
it, that's probably your best choice.

Async delegate uses the thread pool just as BackgroundWorke r does, but it's
harder to use, will have no difference in performance, and is more complex.

I disagree. If you want to just execute an action, without cancelling
or notification while that action is performing on another thread, then I
would say using an asynchronous delegate call, the Thread class, or the
ThreadPool is much easer than the BackgroundWorke r class.

If you need updates from the background thread, and/or the ability to
cancel, then the BackgroundWorke r is the best option.

Hello,

Thanks for your anser.

My thead will communicate (send command/recieve status) through the
Ethernet. The status is a byte array, which I need to display on the screen.

Then you agree. In the case you describe, you have a specific reason not to
use BackgroundWorke r - your use case does not fit well with the
BackgroundWorke r model.

I'm not entirely sure what the difference is between these two approaches. In order to avoid reentrant code, I was using Control.BeginInvoke in my UI to cause an asynchronous activity to be done on the UI's message loop. I began to get System.ExecutionEngineException errors so (on the theory of do something different if what you're doing isn't working) I switched to using delegate.BeginInvoke with the appropriate EndInvoke and the problem...

Hi, I've omitted a large chunk of the code for clarity but the loop below is how I'm calling a delegate function asynchronously. After I start the each call I'm incrementing a counter and then making the main thread sleep until the counter gets back to zero. The call back function for each call decrements the counter. Is there a better way to make the thread wait until all calls are complete besides using the counter? I've seen some things...

I'm using a BackgroundWorker to perform a file download from an ftp site. Per good code design practices where I separate my UI code from my core logic code (in this case my Download file method in my FileIO class) I've established Public Event in my core logic classes along with RaiseEvents (that will updated a progress bar on the UI side). This all works great when I'm NOT using Threading (BackgroundWorker), however, as soon as I...

What happens here? The backgroundworker (bgw) unzips RTF-Helpfiles (up to 1 MB in size). The ProgressChanged-Event gets the unzipped files (to display them in a RichtTextBox) It follows the Trace that prints always what bgw has unzipped and what ProgressChanged received: 1. bgw: HelpFilelistgzip 2. ProgressChanged: HelpFilelistgzip OK!

I'm completely new to using background threading, though I have downloaded and run through several samples and understood how they worked. My question is: I have an app whose primary form will almost always lead to the user opening a certain child window that's fairly resource intensive to load. Is it possible to load this form in a backgroundworker and then use the Show method and hide method as necessary? Anyone know of
