Hi, i'm starting C#, and i have a problem: I'm developing a application that should open one "window", which should be created from a form that has buttons, like a menu selector. When i click the button it should open a new especific form, e.g. button 1 opens form1; button 2 opens form 2 ... That i can do, but i want to open it in the same "window", not openning a new window with my new form, an when i hit a save button i want to go to the previous form. Can´t it be done??? thank for your time.
