How kill thread of backgroundworker

[friend]

Hello all,

how to "kill" or stop the thread of Backgroundworker ?

In my Dowork event, I have not set e.Cancel = true, since i only have
a call to splashscreen which says "Please Wait......".
When my process completes in the current thread, the splashscreen in
backgroundworker should go away

I am doing the cancel for backgorundworker, is by calling CancelAsync,
but the splashscreen doesnt go away

How I can do it , please ? Any suggestions will be very appreciated.

Thanks in advance.

I am using splashscreen1.showdialog() to display the splashscreen.

Hi,

If you had set the work you had to do in a backgroundworker, then you had
made it yourself much easier.

The name is backgroundworker, not foregroundshower.

Maybe you have a special need in a "Splash Screen" to be in a thread,
but Splash screens are normally just *non-modal* popups with little to
no work at all, which you display and can continue with the startup
logic which at some point or delay, you close the popup.

The window (form) methods are:

MySplashForm.Show() <- displays and returns (non-modal)
MySplashForm.ShowDialog() <- displays and waits (modal)

IOW for SplashScreen concepts, you don't need a thread for that.

In the startup event (load maybe), you do:

MySplashForm.Show()

and then when ever you want to close it, you just do:

MySplashForm.Dispose()


Example: With a 10 second timer to simulate work in the main GUI
thread and when its done, it closes the splash screen. The splash
form as a Listbox so the main gui can display a startup log.

Public Class Form1
Private nTimer As Integer = 10

Private Sub Form1_Load( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
MySplash.Show()
Timer1.Enabled = True
End Sub

Private Sub Timer1_Tick( _
ByVal sender As Object, _
ByVal e As System.EventArgs) Handles Timer1.Tick
nTimer = nTimer - 1
MySplash.ListBox1.Items.Add(String.Format("Time {0}", nTimer))
If nTimer <= 0 Then
Timer1.Enabled = False
MySplash.Dispose()
End If
End Sub
End Class
