ISpGrammarBuilder::ResetGrammar

ISpGrammarBuilder::ResetGrammar clears all grammar rules (un-defines them) and resets the grammar's language to NewLanguage. The state handles for this grammar are no longer valid after this point.

  
    HRESULT ResetGrammar(
   LANGID   NewLanguage
);

Parameters

  • NewLanguage
    [in] Language identifier associated with the grammar rule.

Return values

Value
S_OK
FAILED(hr)

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.
}
