ISpRecoContext::SetContextState
ISpRecoContext::SetContextState sets the state of the recognition context.
HRESULT SetContextState(SPCONTEXTSTATE eContextState
);
Parameters
- eContextState
[in] The SPCONTEXTSTATE enumeration sequence specifying the recognition context state.
Return values
| Value |
| S_OK |
| E_INVALIDARG |
| FAILED(hr) |
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.
