Comentarios

El estilo de borde del formulario determina cómo aparece el borde exterior del formulario.The border style of the form determines how the outer edge of the form appears. Además de cambiar la presentación de los bordes de un formulario, ciertos estilos de borde impiden que el formulario tenga el tamaño.In addition to changing the border display for a form, certain border styles prevent the form from being sized. Por ejemplo, el estilo de borde FormBorderStyle.FixedDialog cambia el borde del formulario por el de un cuadro de diálogo y evita que se cambie el tamaño del formulario.For example, the FormBorderStyle.FixedDialog border style changes the border of the form to that of a dialog box and prevents the form from being resized. El estilo de borde también puede afectar al tamaño o la disponibilidad de la sección de la barra de título de un formulario.The border style can also affect the size or availability of the caption bar section of a form.

Nota

Con el estilo de Sizable, no es posible cambiar el tamaño de la ventana por debajo de un determinado valor mínimo, aunque haya establecido ControlBox en false y haya asignado una cadena de longitud cero a Text.With the Sizable style, it is impossible to resize the window below a certain minimum value, even if you have set ControlBox to false and assigned a zero-length string to Text. Considere la posibilidad de solucionar este trabajo mediante el uso del estilo de SizableToolWindow en su lugar.Consider working around this by using the SizableToolWindow style instead.
