Comments

The DTWAIN_SelectDefaultOCREngine function selects the default OCR engine installed on the system, or if there is only one OCR engine installed, DTWAIN selects that particular OCR engine automatically. The default OCR engine is always the last one that was selected by a previous invocation during OCR processing.

Unlike DTWAIN_SelectOCREngine the OCR Select dialog box will not be shown when this function is called.
