Please note that a TWAIN session is a communication session between Leadtools TWAIN and your TWAIN sources. The internal TWAIN session handle that is created provides the user access to this TWAIN session. This method must be called before calling any other methods that require a TWAIN session.
When the TWAIN session is no longer needed, it should be end by calling the Shutdown method. For every call to the Startup2 method there must be a call to the Shutdown method. Use this method if you need to specify the language and country in the UI. Note: If this function throws TwainExceptionCode::InvalidDll exception then this is mostly because you have an old version of TWAINDSM.DLL in your system folder, you need to make sure you have at least version 2.0.9.0 of this DLL. You can download it from www.twain.org.
