Important Notes:
a. The following variables need to be defined before using these macros:
HRESULT hr;
LPOLESTR strGuid;
b. Also, strGuid needs to be initialized to NULL.
c. The function has to return an HRESULT
d. The function has to have a "Cleanup" label which is the one
(and only one) exit from the function.
e. The function should FreeStr(strGuid); during the cleanup phase.
