Hola
Esta bien el juego que consiguió axesys, pero le falto dar unos componentes, bueno de todos modos, como siempre a lo novato lo hice.
Aqui esta el codigo:
Ya colocamos 9 edits y dos botones (Nuevo y Cerrar) en el form, espero que te sirva para aprender un poco mas.
El Codigo completo, muy simple y Mejorable, pero funcional.
