Comentarios

El estilo de borde del formulario determina cómo aparece el borde exterior del formulario. Además de cambiar la presentación del borde de un formulario, ciertos estilos de borde impiden que el formulario se cambie el tamaño. Por ejemplo, el FormBorderStyle.FixedDialog estilo de borde cambia el borde del formulario al de un cuadro de diálogo y evita que se cambie el tamaño del formulario. El estilo de borde también puede afectar al tamaño o la disponibilidad de la sección de la barra de subtítulos de un formulario.
