Declaration

    ServiceCreatorCallback callback,
    bool promote
)

VB.NET

Public Sub AddService(
    serviceType As Type,
    callback As ServiceCreatorCallback,
    promote As Boolean
)

Parameters

Name	Type	Description
serviceType	Type	The type of service to add.
callback	ServiceCreatorCallback	A callback object that is used to create the service. This allows a service to be declared as available, but delays the creation of the object until the service is requested.
promote	Boolean	true, to promote this request to any parent service containers; otherwise, false.

Remarks

The Workbook implements the IServiceProvider and IServiceContainer interfaces. In addition to providing services, it also provides a mechanism for adding and removing services. To obtain a service, call the Workbook.GetService method.

When a service is added, it can be added with instructions to promote it. When a service is promoted, it is added to any parent service container, on up, until the top of the service container tree is reached.
