The Me keyword provides a way to refer to the specific instance of a class or structure in which the code is currently executing. Me behaves like either an object variable or a structure variable referring to the current instance. Using Me is particularly useful for passing information about the currently executing instance of a class or structure to a procedure in another class, structure, or module. For example, suppose you have the following procedure in a module:
Sub ChangeFormColor(ByVal FormName As Form)
Randomize()
FormName.BackColor = Color.FromArgb(Rnd() * 256, Rnd() * 256, Rnd() * 256)
End Sub

ChangeFormColor(Me)
