When I set breakpoint in worker_DoWork,I cannot debug it step by step.For
example, I set breakpoint at System.Threading.Thread.Sleep(20); Then run the
program,it'll break at this statement.At this time,pressing F11,it shoud
move to next statement,but it doesn't.I don't know where the program go to.If
I clear
the breakpoint,everything works very well. I am using VS2005 and testing it
in win2000,XP in my two notebooks(Samsung x10 and HP tc1100).Following is
part of my code:
public partial class Form1 : Form
{
private BackgroundWorker worker;
public Form1()
{
InitializeComponent();
worker = new BackgroundWorker();
worker.WorkerReportsProgress = true;
worker.WorkerSupportsCancellation = true;
worker.DoWork += new DoWorkEventHandler(worker_DoWork);
worker.ProgressChanged += new
ProgressChangedEventHandler(worker_ProgressChanged);
}

void worker_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
label1.Text = e.ProgressPercentage.ToString();
}

void worker_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker wk = (BackgroundWorker) sender;
for (int i = 0; i < 1000; i++)
{
wk.ReportProgress(i);
System.Threading.Thread.Sleep(20);
if (wk.CancellationPending)
{
e.Cancel = true;
return;
}
}


}

private void button1_Click(object sender, EventArgs e)
{
worker.RunWorkerAsync();

}
}

Anybody can give me some advice?By the way,I ask my friends to test it in
desktop,they haven't encounter this problem.
Thanks in advance

After so many test and try,I solve this problem by myself. If you close local
variable
,auto variable debug window,everything is ok.

In case anyone else ever views this thread and are not sure what is
meant by "close local variable' he means for you to close the locals
window.
