```

first member (i.e int)  
DllStructSetData($typUUID, 2, 0xA41E) # Sets data to the  
second member (i.e short)  
DllStructSetData($typUUID, 3, 0x11CF) # Sets data to the  
third

DllStructSetData($typUUID, 4, 0xA7, 1)  
DllStructSetData($typUUID, 4, 0x31, 2)  
DllStructSetData($typUUID, 4, 0x0, 3)  
DllStructSetData($typUUID, 4, 0xA0, 4)  
DllStructSetData($typUUID, 4, 0xC9, 5)
