ISpGrammarBuilder::AddResource adds a resource (name and string value) to the grammar rule specified in hRuleState. The resource can be queried by a rule interpreter.

HRESULT AddResource(
   SPSTATEHANDLE      hRuleState,
   LPCWSTR           *pszResourceName,
   LPCWSTR           *pszResourceValue
);

Parameters

hRuleState

[in] Handle of a state in the rule to which the resource is to be added.

pszResourceName

[in] Address of a null-terminated string specifying the resource name.

pszResourceValue

[in] Address of a null-terminated string specifying the resource value.

Return values

Value	Description
S_OK	Function completed successfully.
E_INVALIDARG	At least one of the parameters is invalid.
SPERR_DUPLICATE_RESOURCE_NAME	The resource already exists.
E_OUTOFMEMORY	Exceeded available memory.
FAILED(hr)	Appropriate error message.

Example

The following code snippet illustrates the use of AddResource.

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

hr = cpGrammarBuilder->GetRule(L"rule1", 1, 0, TRUE, &hInit;);

if (SUCCEEDED (hr))
{
   hr = cpGrammarBuilder->CreateNewState(hInit, &hState;);
}

if (SUCCEEDED (hr))
{
   // Call AddResource using the hInitState.
   hr = cpGrammarBuilder->AddResource(hInit, L"ResName1", L"ResValue1");
}

if (SUCCEEDED(hr))
{
   // Call AddResource using hState != hInit.
   hr = cpGrammarBuilder->AddResource(hState, L"ResName2", L"ResValue2");
}

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