Bug #: 31769
           Summary: windowsx.h macro HANDLE_WM_DISPLAYCHANGE is incorrect
           Product: Wine
           Version: 1.4.1
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

        ReportedBy: [e-mail]
    Classification: Unclassified

windowsx.h macro HANDLE_WM_DISPLAYCHANGE is erroneous:

The CY parameter is not cracked correctly for the function pointer argument.

This is because of a simple typo - the macro is defined thus:
#define HANDLE_WM_DISPLAYCHANGE(hwnd, wParam, lParam, fn) ((fn)((hwnd),
(UINT)(wParam), (UINT)LOWORD(lParam), (UINT)HIWORD(wParam)), 0L)

but should be defined this way:

#define HANDLE_WM_DISPLAYCHANGE(hwnd, wParam, lParam, fn) ((fn)((hwnd),
(UINT)(wParam), (UINT)LOWORD(lParam), (UINT)HIWORD(lParam)), 0L)

HIWORD( wParam ) is incorrectly used for the CY value when in fact it is
encoded in HIWORD( lParam )

That is all.
Thank you for your hard work, great persistence and attention to detail.
