   LANGID   NewLanguage
);

Parameters

Return values

FAILED(hr)	Appropriate error message.

Example

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));
}

if (SUCCEEDED (hr))
{
   hr = cpGrammarBuilder->ResetGrammar(MAKELANGID(LANG_JAPANESE, SUBLANG_DEFAULT));
}

if (SUCCEEDED(hr))
{
   // Do stuff here.
}
