InitPropVariantFromGUIDAsString function

Initializes a PROPVARIANT structure based on a GUID. The structure is initialized as VT_LPWSTR.

Syntax


HRESULT InitPropVariantFromGUIDAsString(
  _In_   REFGUID guid,
  _Out_  PROPVARIANT *ppropvar
);

Parameters

guid [in]

Type: REFGUID

Reference to the source GUID.

ppropvar [out]

Type: PROPVARIANT*

When this function returns, contains the initialized PROPVARIANT structure.

Return value

Type: HRESULT

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

Creates a VT_LPWSTR PROPVARIANT, which formats the GUID in a form similar to {c200e360-38c5-11ce-ae62-08002b2b79ef}.

Examples

The following example, to be included as part of a larger program, demonstrates how to use InitPropVariantFromGUIDAsString.


PROPVARIANT propvar;

HRESULT hr = InitPropVariantFromGUIDAsString(FMTID_DocSummaryInformation, &propvar);

if (SUCCEEDED(hr))
{
    // propvar now is valid and has type VT_LPWSTR.
 
    PropVariantClear(&propvar);
}
