OnActivePageChanged Method of the ITextValidatorEvents Interface
This method is implemented on the client-side. It is called by ABBYY FineReader Engine, after the active page has been changed in Text Validator. The process is invoked in the following situations:
- Text Validator has finished spell checking on one page of the document and proceeded to the next page or the active page is changed via the graphical user interface of any synchronized component
- the active page is changed via the API of Component Synchronizer or any synchronized component
- the active page has been deleted
The method delivers to the client a reference to the new active page.
HRESULT OnActivePageChanged( IFRPage* Page );
void OnActivePageChanged( IFRPage Page );
Visual Basic .NET
Sub OnActivePageChanged(Page As IFRPage)
- [in] Refers to the FRPage object which contains the new active page in the document. This parameter may be NULL, which means that there is no active page in the document (for example, if all the pages are deleted).
[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).
