Cross-thread operation not valid

Cross-thread operation not valid: Control 'ControlName' accessed from a thread other than the thread it was created on
If we try to access a control which is on main thread from a thread, we will get the above exception.
Solution======== Use Delegate Functions to access the controls
Example=======Set the label's text value from the thread
Imports System.Threading
Public Class Form1
Dim updateThread As Thread Dim updateThreadStart As New ThreadStart(AddressOf populateDataBase) Dim CallWorkDone As New MethodInvoker(AddressOf Me.workDone) Dim CallWorkFailure As New MethodInvoker(AddressOf Me.workFailure) ' This delegate enables asynchronous calls for setting ' the cursor type of the cursor. Delegate Sub SetTextCallback(ByVal [text] As String)
Public Sub New()
'Start a threadupdateThread = New Thread(updateThreadStart) updateThread.IsBackground = True updateThread.Name = "UpdateThread" bThreadRunning = True
updateThread.Start()End Sub
Public Sub populateDataBase()
