Represents an asynchronous operation context for validation, merge or commit operations.
The IPrintSchemaAsyncOperation interface inherits from the IDispatch interface. IPrintSchemaAsyncOperation also has these types of members:
The IPrintSchemaAsyncOperation interface has these methods.
Cancels the asynchronous PrintSchema operation.
Starts the asynchronous PrintSchema operation.
Any event sink that implements IPrintSchemaAsyncOperationEvent is connected to the associated event source, IPrintSchemaAsyncOperation, via the IConnectionPoint mechanism. You must retrieve a pointer to the IConnectionPoint interface by invoking QueryInterface on the IPrinterQueue object.
Note 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.
