S_OK | Function completed successfully. |
E_POINTER | One of the pointers is invalid or bad. |
FAILED(hr) | Appropriate error message. |
Example
The following code snippet illustrates the use of ISpRecoGrammar::GetGrammarState to query the default state of an SpRecoGrammar object.
`
// Declare local identifiers: HRESULT hr = S_OK; CComPtr<ISpRecoGrammar> cpRecoGrammar; CComPtr<ISpRecoContext> cpRecoContext; ULONGLONG ullGrammarId = 0; SPGRAMMARSTATE grammarState;`// Create a new grammar object. hr = cpRecoContext->CreateGrammar(ullGrammarId, &cpRecoGrammar;);
if (SUCCEEDED(hr)) { // Query the default grammar state. hr = cpRecoGrammar->GetGrammarState(&grammarState;); }
if (SUCCEEDED(hr)) { // ASSERT that grammarState = SPGS_ENABLED. }
Remarks
The default grammar state is SPGS_ENABLED. See also ISpRecoGrammar::SetGrammarState.
