OnMessage Method of the IProcessingEvents Interface

This method is implemented on the client side. It is called by ABBYY FlexiCapture SDK for some methods of the ClassificationTrainer and DataSetTableRecords objects. It processes any Windows messages to avoid an effect that the application “is not responding” during long operations.


Visual Basic .NET

Sub OnMessage(Message As String)


HRESULT OnMessage( BSTR Message );


[in] This parameter contains the text of the system message.

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).
