[Tutorial] Multi-Threading

[pvash2]

I will be showing you how to use Multi-Threading,
Why is this useful? Instead of having a linear flow of data, you can split up the work load into threads so while you have, for example a counter going, you can have progress be updated to a progress bar as that is happening.

Start by opening up a blank project (NOTE: I am using Visual Basic 2008)

Imports System.Threading.Thread

Private Class Test
   Dim TestThread As System.Threading.Thread 'Define the thread/thread name

   Private Sub Main_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
      Dim TestThread As New System.Threading.Thread(AddressOf TestSub) 'Address the sub which will contain code for our thread
      Control.CheckForIllegalCrossThreadCalls = False 'Allows you to make calls changes to windows form/other threads
      TestThread.Start() 'Initialize the thread
   End Sub

   Public Sub TestSub()
      'Code here
   End Sub
End Class

I discovered this after wondering why my Visual Basic application wasn't responding whenever i tried to execute a hefty amount of code, the multi-threading fixed it.
