问题描述

嗨 如何知道线程中的工作何时完成?

Hi how to know when a work in a thread is complete?

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        Dim firstThread As New Thread(AddressOf Fu1)
        firstThread.Start()

'I want to determine the job of sub (Fun) is finished and then run other code. Normally if i add other code after firstThread.Start() code is running before completed job of Fun (Codes after firstThread.Start() is depended on finished Fun)
End Sub

Sub Fun()
'Something code is here

End Sub

推荐答案

对于线程，您具有myThread.IsAlive属性.如果线程方法返回或线程被中止，则为false.

查看 MSDN [

For a thread you have the myThread.IsAlive property. It is false if the thread method returned or the thread was aborted.

Look at MSDN [^]for details.

Dim firstThread As New Thread(AddressOf Job1)
Dim SecondThread As New Thread(AddressOf Job2)
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        
        firstThread.Start()
        SecondThread.Start()

End Sub

Sub Job1()

'Something code is here

End Sub

Sub Job2()
        While (Job1.IsAlive)
        End While
'Job 2
End Sub

请期待关于Join方法.

Hi try to look forward on Join method.

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        Dim firstThread As New Thread(AddressOf Fu1)
        firstThread.Start()
        firstThread.Join()

'I want to determine the job of sub (Fun) is finished and then run other code. Normally if i add other code after firstThread.Start() code is running before ompleted job of Fun (Codes after firstThread.Start() is depended on finished Fun)
End Sub

Sub Fun()
'Something code is here

End Sub
