Winforms application hangs when switching to another app
- by joseluisrod
Hi, I believe I have a potential threading issue. I have a user control that contains the following code:
private void btnVerify_Click(object sender, EventArgs e)
{
if (!backgroundWorkerVerify.IsBusy)
{
backgroundWorkerVerify.RunWorkerAsync();
}
}
private void backgroundWorkerVerify_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
VerifyAppointments();
}
private void backgroundWorkerVerify_RunWorkerCompleted(object sender, System.ComponentModel.RunWorkerCompletedEventArgs e)
{
MessageBox.Show("Information was Verified.", "Verify",
MessageBoxButtons.OK, MessageBoxIcon.Information);
CloseEvent();
}
vanilla code. but the issue I have is that when the application is running and the users tabs to another application when they return to mine the application is hung, they get a blank screen and they have to kill it. This started when I put the threading code. Could I have some rogue threads out there? what is the best way to zero in a threading problem? The issue can't be recreated on my machine...I know I must be missing something on how to dispose of a backgroundworker properly. Any thoughts are appreciated, Thanks,
Jose
