OnBlockAdded Method of the IImageViewerEvents Interface
This method is implemented on the client-side. It is called by ABBYY FineReader Engine after a new block has been added in Image Viewer.
It delivers to the client the index of the newly added block.
HRESULT OnBlockAdded( int BlockIndex );
void OnBlockAdded( int BlockIndex );
Visual Basic .NET
Sub OnBlockAdded(BlockIndex As Integer)
- [in] Contains the index of the selected block. The index is in the ILayout::VisualBlocks collection.
This method has no specific return values. It returns the standard return values of ABBYY FineReader Engine functions.
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).
