The IsChild function tests whether a given window is a child or other direct descendant of a given parent window. A child window is the direct descendant of a given parent window if that parent window is in the chain of parent windows leading from the original pop-up window to the child window.
hwndParent

hwndChild
Identifies the child window to be tested.
The return value is nonzero if the child window is a descendant of the parent window. Otherwise, it is zero.
