Esta API es compatible con la infraestructura de .NET Framework y no está diseñada para utilizarse directamente desde el código.
Se llama cuando se oculta una ventana.
Espacio de nombres: EnvDTE80
Ensamblado: EnvDTE80 (en EnvDTE80.dll)

'Declaración
Public Overridable Event WindowHiding As _dispWindowVisibilityEvents_WindowHidingEventHandler
public virtual event _dispWindowVisibilityEvents_WindowHidingEventHandler WindowHiding
public:
virtual event _dispWindowVisibilityEvents_WindowHidingEventHandler^ WindowHiding {
void add (_dispWindowVisibilityEvents_WindowHidingEventHandler^ value);
void remove (_dispWindowVisibilityEvents_WindowHidingEventHandler^ value);

Ejemplos
Este ejemplo utiliza un complemento para conectar WindowVisibilityEvents. Reemplace el código del archivo Connect.vb o Connect.cs con el código de ejemplo siguiente. Ejecute este complemento y abra y cierre la Ventana Comandos y la Ventana de salida del entorno de desarrollo integrado de Visual Studio para ver los métodos capturadores de eventos en acción.
