Killing a thread when the application closes...

[nahya^^]

I have a threading that goes on forever so even when I close the application, it still remains in the memory.

I've tried

Private Sub Form1_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing
        Dim f As New Threading.Thread(AddressOf NewTime)
        If f.IsAlive = True Then
            MsgBox("thread f is alive")
        ElseIf f.IsAlive = False Then
            MsgBox("thread f is not alive")
            f.Abort()
        End If
    End Sub

but it didn't work because it said that the thread was not alive.

So I guess I'll have to somehow refer to my existing dimmed thread... but how would I do that?

Thanks.
