The following code snippet illustrates the use of ResetGrammar.

`

// Declare local identifiers:
HRESULT                       hr = S_OK;
CComPtr<ISpGrammarBuilder>    cpGrammarBuilder;


// ResetGrammar when no rules.
hr = cpGrammarBuilder->ResetGrammar(409);


if (SUCCEEDED (hr))
{
// Set language to default user language.
hr = cpGrammarBuilder->ResetGrammar(SpGetUserDefaultUILanguage());
}


if (SUCCEEDED (hr))
{
// Set language to non-english.
hr = cpGrammarBuilder->ResetGrammar(MAKELANGID(LANG_CHINESE, SUBLANG_CHINESE_SIMPLIFIED));
}
