A pointer to the object implementing this interface is returned by the GetEngineLoader function. Use it to load and unload the Engine object. The properties described below provide easy access to online licensing if needed and also allow you to specify some additional parameters of the Engine object. One of the properties is the Customer Project ID number, which is an alphanumeric string common to all the Developer and Runtime licenses your project uses.
Note: During library initialization the list of all available licenses is searched for a Developer or Runtime License corresponding to this Customer Project ID. If no corresponding license is found, an error for the last checked license will occur. However, you may pass 0 for this parameter and select the license later, by calling the IEngine::SetCurrentLicense method before any other library methods.
This interface is also available in the InprocLoader and OutprocLoader objects, which allow you to load ABBYY FlexiCapture SDK by means of COM either as an in-process server into the current process or as an out-of-process server into a separate process. For more information, please refer to the Different Ways to Load the Engine Object section.
Please note that you must keep the reference to the loader object until you finish working with the Engine. You can then call the Unload method of the loader object to deinitialize the Engine, and then destroy the loader object.
