Thu May 16 13:35:31 1996 Alexandre Julliard <julliard@lrc.epfl.ch>
* [*/*.c]
Renamed RECT, POINT and SIZE structures to RECT16, POINT16 and
SIZE16. Implemented Win32 version of most functions that take
these types as parameters.
* [configure]
Patched autoconf to attempt to correctly detect -lnsl and
-lsocket. Please check this out.
* [controls/button.c]
Added support for Win32 BM_* messages.
* [controls/menu.c]
Avoid sending extra WM_MENUSELECT messages. This avoids crashes
with Excel.
* [memory.heap.c] [include/heap.h]
Added support for SEGPTRs in Win32 heaps. Added a few macros to
make using SEGPTRs easier. They are a bit slower than MAKE_SEGPTR,
but they work with Win32.
* [memory/atom.c]
Implemented Win32 atom functions.
* [memory/local.c]
Fixed LocalReAlloc() changes to avoid copying the whole block twice.
* [win32/memory.c]
Use /dev/zero instead of MAP_ANON for VirtualAlloc().
* [windows/class.c]
Properly implemented the Win32 class functions.
* [windows/winproc.c] (New file)
New file handling the message translation between Win16 and Win32.
Mon May 13 18:00:00 1996 Alex Korobka <alex@phm30.pharm.sunysb.edu>
* [windows/mdi.c] [windows/menu.c]
Improved WM_MDICREATE and WM_MDICASCADE handling.
* [windows/event.c] [objects/bitblt.c]
Handle GraphicsExpose event for BitBlt from screen to screen.
* [windows/event.c] [windows/win.c] [windows/nonclient.c]
Bunch of fixes for problems with -managed.
* [windows/win.c] [windows/winpos.c]
Changed conditions for WM_SIZE, WM_MOVE, and WM_GETMINMAXINFO
in CreateWindow.
* [windows/win.c] [windows/queue.c] [misc/user.c]
Do not send WM_PARENTNOTIFY when in AppExit and call WH_SHELL
on window creation/destruction.
* [objects/palette.c]
Crude RealizePalette(). At least something is visible in LviewPro.
Sun May 12 02:05:00 1996 Thomas Sandford <t.d.g.sandford@prds-grn.demon.co.uk>
* [if1632/gdi32.spec]
Added Rectangle (use win16 version).
* [if1632/kernel32.spec]
Added GetWindowsDirectoryA (use win16 GetWindowsDirectory).
* [if1632/user32.spec]
Added GetSubMenu, MoveWindow, SetScrollPos, SetScrollRange (use win16
versions).
Added SetWindowsHookExA (empty stub for now).
* [include/handle32.h]
Changed #include <malloc.h> to #include <stdlib.h> to prevent
hate message from FreeBSD compiler.
* [win32/newfns.c]
Added new function SetWindowsHookEx32A (empty stub for now).
* [win32/user32.c]
Removed redundant debugging printf statement.
Sun May 12 01:24:57 1996 Huw D. M. Davies <h.davies1@physics.oxford.ac.uk>
* [memory/local.c]
Avoid creating adjacent free blocks.
Free the block in LocalReAlloc() before allocating a new one.
Fixed LocalReAlloc() for discarded blocks.
Fri May 10 23:05:12 1996 Jukka Iivonen <iivonen@cc.helsinki.fi>
* [resources/sysres_Fi.rc]
ChooseFont and ChooseColor dialogs updated.
Fri May 10 17:19:33 1996 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de>
* [files/drive.c,if1632/kernel.spec]
GetCurrentDirectory(),SetCurrentDirectory() implemented.
* [if1632/advapi32.spec] [if1632/kernel.spec] [if1632/shell.spec]
[include/windows.h] [include/winreg.h] [loader/main.c]
[misc/main.c] [misc/shell.c] [misc/registry.c]
Registry fixes:
- loads win95 registry databases,
- save only updated keys on default,
- now adhers to the new function naming standard,
- minor cleanups.
Tue May 7 22:36:13 1996 Albrecht Kleine <kleine@ak.sax.de>
* [combo.c]
Added WM_COMMAND-handling for interaction between EDIT and COMBOLBOX
and synchronized mine with Greg Kreider's works.
* [commdlg.c]
Bugfix in ChooseFont: font size handling.
