Chinese Simplified (简体中文)
OnWarning Method of the IFRPageEvents Interface
This method is implemented on the client-side. It is called by ABBYY FineReader Engine for some of the methods of the FRPage object. It delivers to the client tips and warnings which occurred during processing.
Syntax
HRESULT OnWarning(
IFRPage* Sender,
BSTR Warning,
VARIANT_BOOL* Cancel
);
Parameters
- Sender
- [in] Refers to the FRPage object which sends notifications.
- Warning
- [in] Contains the tip or warning.
- Cancel
- [in, out] You may set this variable to TRUE to indicate that the process should be terminated. In this case, the processing function that reports the tip 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 Cancel parameter is not taken into account.
Remarks
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).
