The IsChild function tests whether a window is a child window or descendant window of a specified parent window. A child window is the direct descendant of a specified parent window if that parent window is in the chain of parent windows; the chain of parent windows leads from the original overlapped or pop-up window to the child window.

BOOL IsChild(

HWND hWndParent,	// handle of parent window
HWND hWnd	// handle of window to test
);

Parameters
hWndParent

hWnd

Identifies the window to be tested.

Return Values
If the window is a child or descendant window of the specified parent window, the return value is nonzero.

If the window is not a child or descendant window of the specified parent window, the return value is zero.
