[out] UINT *pcchActual
);
Parameters

Type: WCHAR*
A pointer that receives a culture invariant string of the component's version.
[out] pcchActual
Type: UINT*
A pointer that receives the actual length of the component's version. The version is optional; if a value is not specified by the component, the length returned is 0.
Return value
Type: HRESULT
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
