OnPageProcessed Method of the IFRDocumentEvents Interface

This method is implemented on the client-side. It is called by ABBYY FineReader Engine for some of the methods of the FRDocument object. It delivers to the client information about page processing completed. It may process any Windows messages to avoid an effect that the application "is not responding" during long operations.

  Stage As PageProcessingStageEnum _

Return values

[C++ only] If this method returns a value other than S_OK, it indicates that an error occurred on the client-side.


The client implementation of this method must assure that all exceptions thrown inside the method are caught and handled and no exceptions are propagated outside the method. Propagation of an exception outside the method may lead to unpredictable results (such as program termination).
