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.
