Atributos

SecurityCriticalAttribute

Ejemplos

En el ejemplo siguiente se usa RestoreBounds y el almacenamiento aislado para asegurarse de que el tamaño y la ubicación de una ventana son los mismos que la hora anterior en que se mostró la ventana.

Comentarios

El rectángulo de restauración es la región ocupada por la ventana antes de minimizarla o maximizarse. Puede usar RestoreBounds para guardar el último tamaño y la ubicación de una ventana antes de que se cierre una aplicación y recuperar esos valores la próxima vez que una aplicación empiece a restaurar una ventana a la manera en que un usuario lo dejó.

Si consulta RestoreBounds antes de que se haya mostrado la ventana o después de cerrarla, Empty se devuelve.
