backgroundworker

i am new to this backgroundworker thing i have read some articles about how to create one this is what it produced private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e) { Bitmap imgbox = new Bitmap(pictureBox.Image); int imgHeight = imgbox.Height; int imgWidth = imgbox.Width; int counter = 1; MinMaxWidth = imgWidth - 50; MaxWidth = imgWidth; try { Color c; //Color c2; for (int i = 0; i < imgbox.Width; i++) { for (int j = 0; j < imgbox.Height; j++) { c = imgbox.GetPixel(i, j); string cn = c.Name; counter++; backgroundWorker1.ReportProgress(counter); } } MessageBox.Show(

Is there a easy way to perform a method after a given delay like in iOS out of the box? On iPhone I would do this: [self performSelector:@selector(connectSensor) withObject:nil afterDelay:2.5]; It will then schedule the method connectSensor on the main thread (UI thread) to be executed after 2,5 seconds. And because it is automatically scheduled on the main thread, you don't have to worry about cross thread issues. (There is also a performSelectorOnBackground version) So how would I do this properly in WP7? Currently I'm accomplishing this with a timer, but I'm not sure if this is a good

My questions are many. Since I saw. NET 4.5, I was very impressed. Unfortunately all my projects are .NET 4.0 and I am not thinking about migrating. So I would like to simplify my code. Currently, most of my code that usually take enough time to freeze the screen, I do the following: BackgroundWorker bd = new BackgroundWorker(); bd.DoWork += (a, r) => { r.Result = ProcessMethod(r.Argument); }; bd.RunWorkerCompleted += (a, r) => { UpdateView(r.Result); }; bd.RunWorkerAsync(args); Honestly, I'm tired of it. And that becomes a big problem when there is a logic complex user interaction. I wonder,

I am one of those accidental programmer so I don't have that much knowledge regarding programming best practice. I have an application that currently uses 4 Background Worker. So I declare them: private BackgroundWorker bw1; private BackgroundWorker bw2; private BackgroundWorker bw3; private BackgroundWorker bw4; Then configure them: bw1 = new BackgroundWorker(); bw1.WorkerReportsProgress = true; bw1.DoWork += new DoWorkEventHandler(bw1_DoWork); bw1.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw1_RunWorkerCompleted); bw1.ProgressChanged += new ProgressChangedEventHandler(bw

I know this questions gets asked a bit (at least from what I found here so far), but I can't really wrap my head around it. Already tried it with the example from msdn but still no succes. Here is what I'm trying to do: I have a USB-Counter connected to a TLL-ruler. I want to read the value constantly in a loop and write the readout to a textbox without blocking the main UI. I know from other questions that I should use Invoke or Backgroundworker, but have not really found an example which I understood and could use to adjust my code accordingly. The code without any modification, to keep it
