Remarks
The default recognition context state for an ISpRecoContext object is SPCS_ENABLED.
Applications can use ISpRecoContext::SetContextState to toggle sets of grammars. For example, a multi-document interface application that uses a different ISpRecoContext object for each document could toggle the context states as each document gained and lost the focus.
Applications can use ISpRecoContext::GetContextState to query the context state.
