Parameters

LogFileName [in] This parameter contains the full path to the log file. If the file does not exist, it will be created. WriteMethodCalls [in] This parameter enables logging calls of ABBYY FineReader Engine methods to the log file. The format is as follows: <time of call>, <duration of execution (in ms)>, <Interface::Method (parameter1, … )> For example, 12:40:31.254, 17 ms, IRecognizerParams::put_OneWordPerLine( VARIANT_TRUE )

​
Return values

This method has no specific return values. It returns the standard return values of ABBYY FineReader Engine functions.

​
Remarks

The log file can contain a list of objects that have not been deleted before the deinitialization of the Engine object. To do this, do not call the StopLogging method which disables logging, before the deinitialization.
