I am creating an application that makes multiple connections simultaneously. For each connection I create one TextBox and a BackgroundWorker. When executing the DoWork of BackgroundWorker I use several ProgressPercentage that initiate various types of functionality, from starting a timer to placing messages on TextBox.
My doubt is, when I do the routine on DoWork I left some exceptions as throw new NotImplementedException(); and implemented in RunWorkerCompleted a treatment for when that kind of mistake happened. However, when I am debugging, I end up stopping in the creation of error and not in the treatment within the RunWorkerCompleted.
How do I get the error treated within the RunWorkerCompleted?
Below follows part of the code.
private void bgwMain_DoWorkSerial(object sender, DoWorkEventArgs e)
{
startDownloadSerial();
}
private void bgwMain_ProgressChangedSerial(object sender, ProgressChangedEventArgs e)
{
switch (e.ProgressPercentage)
{
case 0:
msgTextDownload("Iniciando processo de download via Serial.");
break;
case 1:
tmrDownloadDot = new Timer();
tmrDownloadDot.Interval = 1000;
tmrDownloadDot.Tick += TmrDownloadDot_Tick;
msgTextDownload("Download iniciado.");
msgTextDownload("");
tmrDownloadDot.Start();
break;
case 2:
tmrDownloadDot.Stop();
msgTextDownload("Download finalizado.");
break;
default:
throw new NotImplementedException();
}
}
private void bgwMain_RunWorkerCompletedSerial(object sender, RunWorkerCompletedEventArgs e)
{
if (e.Cancelled)
{
msgTextDownload("Operação cancelada pelo usuário.");
}
else if (e.Error != null)
{
msgTextDownload("Ocorreu um erro durante a aplicação: ");
msgTextDownload("Source:" + e.Error.Source + "| Message: " + e.Error.Message);
}
else
{
msgTextDownload("Processo de download via serial finalizado.");
if (e.Result != null)
{
try
{
msgTextDownload(e.Result.ToString());
}
catch (Exception ex)
{
}
}
}
}
In the code, the method msgTextDownload only prints the text in TextBox corresponding to BackgroundWorker.
