    <p>i'm new to winform and i can't figure out how to use the BackgroundWorker.</p> <p>basically what i'm trying to do is this:</p> <p>i have 1 form with 2 buttons: "Import" and "Exit" . when calling ImporButton_Click all it does is creates an HttpListener and listen to a given URL. ExitButton_Click closes the form.</p> <p>the problem is when i press "Import" the form get stuck and it's in "not responding" status until someone is calling the listener and free it.</p> <p>i'm trying to under stand how BackgroundWorker can help me to overcome that "stuck" problem. i don't understand how to invoke the backgroundWorker1_DoWork method</p> <p>Here is my code so far:</p> <pre><code>//Program.cs static class Program { /// &lt;summary&gt; /// The main entry point for the application. /// &lt;/summary&gt; [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new ConfigurationForm()); } } //ConfigurationForm.cs public partial class ConfigurationForm : Form { public ConfigurationForm() { InitializeComponent(); UrlTextBox.Text = @"enter URL here"; } private void ImporButton_Click(object sender, EventArgs e) { try { String urlToListen = UrlTextBox.Text; //Invoke MyListener MyListener.StartListen(urlToListen); //assume this is implemented } catch (Exception exception) { string errorMsg = String.Format("An exception occured = {0}", exception); MessageBox.Show(errorMsg); } } private void ExitButton_Click(object sender, EventArgs e) { this.Close(); } private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e) { } } </code></pre> <p>so, what now ? how do i invoke the backgroundWorker1_DoWork ???</p> <p>10x to anyone who can help </p>

    1. COYou don't show the code where your real problem lies leaving as *"assume this is implemented"* :) For example , see [this](http://stackoverflow.com/questions/10017564/url-mapping-with-c-sharp-httplistener) or [this](http://stackoverflow.com/questions/13385633/serving-large-files-with-c-sharp-httplistener)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
