Type Parameters

Returns

Type	Description
T	A service object of the specified type or null for reference types and zero for numeric value types if a service is not available.

Remarks

Use this method to enable your application objects to obtain a service of the RichEdit Control, in order to employ methods of the service. The control implements the IServiceProvider interface, so you can tell it what type of service you wish to retrieve; and if a service is available, it is offered to the caller object.

There is a set of predefined services you can retrieve. The IServiceProvider and IServiceContainer interface realization allows hiding implementation details, and provides more flexibility regarding future updates of the component.

Example

The following code replaces the IRichEditCommandFactoryService service with its customized descendant.
