How to abort a thread?

[yxq]

Hello,
I want to abort a thread when form closed, but system will hang using the
code below sometimes.

*****************************************************
Private Sub frm1_Closed(ByVal sender As Object, ByVal e As System.EventArgs)
Handles MyBase.Closed
If ScanThread.ThreadState <> ThreadState.Stopped Then
ScanThread.Abort()
Do Until ScanThread.ThreadState = ThreadState.Stopped
Application.DoEvents()
Loop
End If
End Sub

Take a look at the background property of the thread class.

Setting the threads' 'IsBackground' property to 'True' will cause them to be
terminated automatically when the main thread terminates.
