Multithreading with queue

[winzone]

Hi All,

I have more than 5 thread task that is dynamic number.

I want to run 5 thread at a time.
when one of the 5 thread is finished another one queue thread start to run.
Then continue to run until all queue thread is finished.

I have problem of how to queue the thread if over 5 thread.
how to pass the parameter? sPar.Item(iIndx ).ToString()

Below is my code.

 Private Const MAX_THREADS As Integer = 7
    Private threads(MAX_THREADS) As Thread
Private Sub btnRunThread_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnRunThread.Click
        Dim cThread As New ThreadClass
        Dim rnd As New Random
        
        For i As Integer = 0 To MAX_THREADS
            cThread.sPar.Add(i.ToString())
            If i > 4 Then
                threads(i) = New Thread(AddressOf cThread.ThreadMethod1)
                cThread.iIndx = i
                threads(i).Start()
                threads(i).Join()
            Else
                threads(i) = New Thread(AddressOf cThread.ThreadMethod1)
                cThread.iIndx = i
                threads(i).Start()
            End If
        Next
End Sub

Public Class ThreadClass
    Public sPar As New ArrayList
    Public iIndx As Integer
    
    Public Sub ThreadMethod1()
        Thread.Sleep(200)
        For i As Integer = 1 To 100
            Console.WriteLine("Thread " & sPar.Item(iIndx).ToString() & ": " & i)
        Next
    End Sub
End Class

Is there any solution or advice, please guide me.
