OnDocumentChanged Method of the IDocumentViewerEvents Interface
This method is implemented on the client-side. It is called by ABBYY FineReader Engine, after the active document has been changed in Document Viewer. The process is invoked if the new document is specified via the IDocumentViewer::FRDocument property.
The method delivers to the client a reference to the new active document.
HRESULT OnDocumentChanged( IFRDocument* Document );
void OnDocumentChanged( IFRDocument Document );
Visual Basic .NET
Sub OnDocumentChanged(Document As IFRDocument)
- [in] Refers to the FRDocument object which contains the new active document.
[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).
