    When the window procedure receives the WM_NCCALCSIZE message, the first rectangle contains the new coordinates of a window that has been moved or resized, that is, it is the proposed new window coordinates. The second contains the coordinates of the window before it was moved or resized. The third contains the coordinates of the window's client area before the window was moved or resized. If the window is a child window, the coordinates are relative to the client area of the parent window. If the window is a top-level window, the coordinates are relative to the screen origin.

    When the window procedure returns, the first rectangle contains the coordinates of the new client rectangle resulting from the move or resize. The second rectangle contains the valid destination rectangle, and the third rectangle contains the valid source rectangle. The last two rectangles are used in conjunction with the return value of the WM_NCCALCSIZE message to determine the area of the window to be preserved.

Private Shared Function RealChildWindowFromPoint(hwndParent As IntPtr, ptParentClientCoords As POINT) As IntPtr

<DllImport("user32", CharSet:=CharSet.Ansi, SetLastError:=True, ExactSpelling:=True)> Public Function RealChildWindowFromPoint(ByVal hwndParent As IntPtr, ByVal ptParentClientCoords As POINTAPI) As IntPtr

/** this takes the POINT, which is using screen coords (0,0 in top left screen) and converts them into coords inside specified window (0,0 from  top left of hWnd) **/

The last bit of the above example is incorrect. The correct client left/top will be retrieved but the width/height will be inaccurate. This function reports the distance of any given screen coordinates from the origin of our hwnd's ClientRect. In this way it allows us to deduce the location of the ClientRect origin given any other point. It does not allow us to deduce the location of any other point of the ClientRect, just the origin. The above example errs by trying to use this to deduce the distance from the ClientRect origin to the WindowRect bottom/right. This is not helpful because it will not give the accurate height and width of the ClientRect since the WindowRect bottom/right will be further out and different than the yet unknown ClientRect. The origin is deducible because that's where the function reports from, but this is not true of any other point in the ClientRect. So the proper way to use this is to make only the first call to ScreenToClient and then call GetClientRect to retrieve the ClientRect dimensions and add them to the origin.
