vb.net - Modify a control (winforms) through another thread

Question

I have this code:

Public Class main

    Public Shared classOne As classOne 
    Public Shared classTwo As classTwo

    Public Shared Sub main()

        classOne = new classOne()
        classTwo = new classTwo()

        classTwo.myThread.Start()

        Application.Run(classOne)
    End Sub

End Class

classOne is a simple winforms with a textlabel. I just would like modify the background color of this textlabel from classTwo but there is a problem because classTwo is in an other thread.

I know I must use a delegate and invoke method but i don't know how to do it. Where should I declare the delegate function and where I have to use invoke method please? I have already ridden the MSDN documentation but I failed to apply it...

Answer 1

Please read the following articles:

MSDN - How to: Make Thread-Safe Calls to Windows Forms Controls

MSDN - How to: Use a Background Thread to Search for Files

MSDN - Control.Invoke Method (Delegate, Object())

MSDN - Control.InvokeRequired Property

i guess this is too much for people. :
