ISpObjectTokenCategory::EnumTokens

ISpObjectTokenCategory::EnumTokens enumerates the tokens for the category by attempting to match specified requirements. Attributes, enumerations, and searches are discussed in Object Tokens and Registry Settings White Paper.

  
    HRESULT EnumTokens(
   LPCWSTR               *pszReqAttribs,
   LPCWSTR               *pszOptAttribs,
   IEnumSpObjectTokens  **ppEnum
);

Parameters

  • pszReqAttribs
    [in] The null terminated string of required attributes for the token.
  • pszOptAttribs
    [in] The null terminated string of optional attributes for the token. The order in which the tokens are listed in ppEnum is based on the order they match pszOptAttribs.
  • ppEnum
    [out] The enumerated list of tokens found.

Return values

Value
S_OK
SPERR_UNINITIALIZED
E_POINTER
FAILED(hr)

Example

The following code snippet demonstrates getting a complete enumerated token list. Since no specific requirement is given (pszReqAttribs and pszOptAttribs are NULL), all values are returned for SPCAT_VOICES.

  
// Declare local identifiers:
HRESULT                           hr = S_OK;
CComPtr<ISpObjectTokenCategory>   cpSpObjectTokenCategory;
CComPtr<IEnumSpObjectTokens>      cpSpEnumTokens;

hr = SpGetCategoryFromId(SPCAT_VOICES, &cpSpObjectTokenCategory;);

if (SUCCEEDED (hr))
{
   hr = cpSpObjectTokenCategory->EnumTokens(NULL, NULL, &cpSpEnumTokens;);
}

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