vb.net 2008 子线程控制父窗体控件

[snow_kit]

RT 我想知道 这个 要怎么来实现的

我的想法是 窗体用一个线程来重绘 数据用一个线程来处理

找了下 没能够成功找到 invoke的用法

分不够可以再加

对了 我不想使用全局变量........

[oluckly]

Private Delegate Sub DelegateUI()
Private EventUI As New DelegateUI(AddressOf ShowData)

Dim T As Thread
'开始运行线程1()
T = New Thread(AddressOf ExecutCmdThread)
T.Start()

Private Sub ExecutCmdThread()
Me.Invoke(EventUI, Nothing)

End Sub
Private Sub ShowData()
....
End Sub

上面这段 明白了

那么这里的参数Nothing 怎么弄的 ，老是报参数数量不匹配.....

[snow_kit]

OK 问题解决 ..........

  Private Delegate Sub DelegateUI(str as string) 
  Private EventUI As New DelegateUI(AddressOf ShowData) 

  Dim T As Thread 
  '开始运行线程1() 
  T = New Thread(AddressOf ExecutCmdThread) 
  T.Start() 

Private Sub ExecutCmdThread() 
        Me.Invoke(EventUI, "dkslajdfklsa") 
    
End Sub 
Private Sub ShowData(str as string) 
.... 
End Sub
