不可以,但是能夠在主線程的基礎(chǔ)上調(diào)用委托(Invoke)。(主線程會(huì)被占用)

例子:
Dim thr As Threading.Thread
Public Delegate Sub VoidDelegate()
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
thr = New Threading.Thread(AddressOf Where)
thr.Start()
End Sub
Public Sub Where()
Me.BeginInvoke(New VoidDelegate(AddressOf WhereThr))
End Sub
Public Sub WhereThr()
Me.TextBox.text="0123456789"
End Sub
(Invoke)這種情況下,主線程被占用,所有由主線程執(zhí)行程序,都將被(wherethr函數(shù)執(zhí)行結(jié)束)后執(zhí)行。
Sub Main() Dim thr As New Thread(AddressOf 循環(huán)) thr.Start("a") End Sub Sub 循環(huán)(a() As String) '這里隨你干什么循環(huán)也行 For Each i As String In a MsgBox(i) Next End Sub
Sub Main()
Dim thr As Thread
For Pi As Integer=0 To 4 //啟用5線程
MulParams =Pi vbTab sFile vbTab dFile vbTab 1 vbTab DelN vbTab cr vbTab cg vbTab cb vbTab IndexI
GlobalParamas(pi)=MulParams .Split(vbTab)
thr=New Thread(AddressOf MyMulThreadCaller)
thr.Start() //啟動(dòng)多線程進(jìn)程
Application.DoEvents
Next
End Sub
