IPrintSchemaAsyncOperationEvent interface (printerextension.h)
Exposes a validation, merge, or commit completion event delegate.
Inheritance
The IPrintSchemaAsyncOperationEvent interface inherits from the IDispatch interface.
Methods
The IPrintSchemaAsyncOperationEvent interface has these methods.
| IPrintSchemaAsyncOperationEvent::Completed Is called when asynchronous PrintSchema operation that is represented by an IPrintSchemaAsyncOperation context is completed. |
Remarks
An event sink that implements IPrintSchemaAsyncOperationEvent and the event source, IPrintSchemaAsyncOperation are connected via the IConnectionPoint mechanism. You must retrieve a pointer to the IConnectionPoint interface by invoking QueryInterface on the IPrinterQueue object.
It is mandatory to implement IDispatch::Invoke on the event sink that implements IPrinterQueueEvent, since that is the mechanism via which events are raised. It is sufficient to provide stub implementations of the other methods on the IDispatch interface.
