EnumChildWindows function (winuser.h)
Enumerates the child windows that belong to the specified parent window by passing the handle to each child window, in turn, to an application-defined callback function. EnumChildWindows continues until the last child window is enumerated or the callback function returns FALSE.
[in, optional] HWND hWndParent,
[in] WNDENUMPROC lpEnumFunc,
[in] LPARAM lParam
[in, optional] hWndParent
A handle to the parent window whose child windows are to be enumerated. If this parameter is NULL, this function is equivalent to EnumWindows.
A pointer to an application-defined callback function. For more information, see EnumChildProc.
An application-defined value to be passed to the callback function.
The return value is not used.
If a child window has created child windows of its own, EnumChildWindows enumerates those windows as well.
A child window that is moved or repositioned in the Z order during the enumeration process will be properly enumerated. The function does not enumerate a child window that is destroyed before being enumerated or that is created during the enumeration process.
