EnumChildWindow and receiving a duplicate HWND

Question

I am enumerating through the children of a given window with the help of EnumChildWindow. I want to store the received window handles (via EnumChildProc) in a collection. Is it guaranteed that the received handles are unique? According to the MSDN article it sounds like they are unique during the enumeration but I am not sure if I understand it correctly ;)

Answer 1

Yes, they're unique during the enumeration. You get a shapshot.
