OnProcessMessages Method of the IBatchEvents Interface

This method is implemented on the client side. It is called by ABBYY FlexiCapture SDK for some of the methods of the Project and Batch objects. It allows the client to terminate the current operation of batch processing (Document Definitions matching, recognition, or export). It may also process any Windows messages to avoid an effect that the application "is not responding" during long recognition operations.


Visual Basic .NET

Sub OnProcessMessages(ByRef ShouldTerminate As Boolean)


HRESULT OnProcessMessages(
  VARIANT_BOOL* ShouldTerminate


[in, out] You may set this variable to TRUE to indicate that the process should be terminated. In this case the current processing function returns E_ABORT.

Return values

[C++ only] If this method returns a value other than S_OK, it indicates that an error occurred on the client side, and in this case the value of the ShouldTerminate parameter is not taken into account.


A 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).
