I'm moving the object to another class, but there's a part I don't
know where to put ...
In the code I wrote I had :
static void Main()
{
Program.sel_activa = new Seleccion();
... }
Main es the starting thread which is only in the program class. Where
should I put this line, or what should I do to define the sel_activa?
