Initializes a VARIANT structure based on a GUID. The structure is initialized as a VT_BSTR type.

PSSTDAPI InitVariantFromGUIDAsString(
  [in]  REFGUID guid,
  [out] VARIANT *pvar
);

VARIANT var;

HRESULT hr = InitVariantFromGUIDAsString(FMTID_DocSummaryInformation, &var);

{
    // var now is valid and has type VT_BSTR.
    VariantClear(&var);
}
