   int WordIdx
) 
public:
String^ GetWordRecognitionLanguage( 
   String^ OCRResultID,
   int WordIdx
) 

Parameters

OCRResultID
The unique result identifier of the executed OCR process obtained by the RunOCR method.
WordIdx
The 0-based index of the word within the specified OCR result. It must be a value between 0 and GetWordCount(OCRResultID) - 1.

Return Value

The name of the used language. Please always use the GetStat method to determine if this method has been successful.
Remarks
It is recommend to use the GetStat method to identify the specific reason for the method's failure, if any.
Example
How to find out the number of recognized words within the OCR result and some of the word's properties.
