InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
// backgroundworker
BackgroundWorker bw = new BackgroundWorker();
bw.DoWork += new DoWorkEventHandler(bw_DoWork);
bw.ProgressChanged += new ProgressChangedEventHandler(bw_ProgressChanged);
bw.WorkerReportsProgress = true;
bw.RunWorkerAsync();
// own event
LongRunningTaskClass ltrc = new LongRunningTaskClass();
ltrc.Progress += new LongRunningTaskClass.ProgressEventDelegate(ltrc_Progress);
Thread t = new Thread(new ThreadStart(ltrc.LongRunningTask));
t.Start();
}
void ltrc_Progress(object sender, int percentage)
{
Debug.WriteLine("Own Event: " + percentage.ToString());
}
void bw_DoWork(object sender, DoWorkEventArgs e)
{
