I am trying to run a function in a different class than the dispatcher through a backgroundworker and have it update the progress on every iteration. I am getting no errors and the backgroundworker is functioning properly, but my textbox never updates...
public partial class MainWindow : Window
{
public BackgroundWorker worker = new BackgroundWorker();
public MainWindow()
{
InitializeComponent();
worker.WorkerReportsProgress = true;
worker.DoWork += new DoWorkEventHandler(workerDoWork);
worker.ProgressChanged += new ProgressChangedEventHandler(workerProgressChanged);
}
private void myButtonClick(object sender, RoutedEventArgs e)
{
worker.RunWorkerAsync();
}
void workerDoWork(object sender, DoWorkEventArgs e)
{
yv_usfm.convert(worker);
}
void workerProgressChanged(object sender, ProgressChangedEventArgs e)
{
myTextBox.Text = "some text";
}
}
public class yv_usfm
{
public static void convert(BackgroundWorker worker)
{
int i = 1;
while (i < 100)
{
worker.ReportProgress(i);
i++;
}
}
}
What makes you say the BackgroundWorker
is functioning properly? I see no call to worker.RunWorkerAsync()
, and without that it will never start.
您不是要启动工作人员!
worker.RunWorkerAsync();
Try This:
void DoWork(...)
{
YourMethod();
}
void YourMethod()
{
if(yourControl.InvokeRequired)
yourControl.Invoke((Action)(() => YourMethod()));
else
{
//Access controls
}
}
Hope This help.
