hola bakunos quisiera saber si alguien me podria ayudar con un codigo de visual studio 2008 no soy muy bueno pero estoy aprendiendo, quisiera saber como hacer para que una ventana hijo guarde los cambios que se hacen,

Si maximizo la ventana hijo al cerrarla guarde los cambios, si la minimizo se guarden los cambios.

la ventana hijo la tengo dentro de una ventana padre, la cual la ventana padre trae un menu que al darle clic en maximizar, maximiza todas las ventanas. que tengo abiertas dentro de la ventana padre

espero y alguien pueda ayudarme: este es el codigo si gustan pegarlo y ver. falta mas pero eso es lo de la ventana.
