Well actually Ooble's 'Form2.Show' cant work as long as you havent a static/shared method in your class 'Form2' called 'Show'.
You have to call 'Show' from a created instance of the class 'Form2'. I think its in VB.NET something like this:
Dim formInstance As Form2 = New Form2 // class member
formInstance.Show() // call this in a method
