StartLogging Method of the Engine Object

This method enables logging of errors, warnings and method calls.

Syntax

C++

HRESULT StartLogging(
  BSTR         LogFileName,
  VARIANT_BOOL WriteMethodCalls
);

C#

void StartLogging(
  string LogFileName,
  bool   WriteMethodCalls
);

Visual Basic .NET

Sub StartLogging( _
  LogFileName As String, _
  WriteMethodCalls As Boolean _
)

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.
