WindowFromPoint function (winuser.h)

Retrieves a handle to the window that contains the specified point.

HWND WindowFromPoint(
  [in] POINT Point
);

[in] Point

Type: POINT

The point to be checked.

Type: HWND

The return value is a handle to the window that contains the point. If no window exists at the given point, the return value is NULL. If the point is over a static text control, the return value is a handle to the window under the static text control.

The WindowFromPoint function does not retrieve a handle to a hidden or disabled window, even if the point is within the window. An application should use the ChildWindowFromPoint function for a nonrestrictive search.

For an example, see "Interface from Running Object Table" in About Text Object Model.
