Wed Jan 1 15:36:17 1997 Alexandre Julliard <julliard@lrc.epfl.ch>
* [controls/listbox.c]
Use FindFirstFile/FindNextFile in LISTBOX_Directory.
* [files/dos_fs.c]
Rewrote FindFirstFile/FindNextFile to use DOSFS_FindNext().
* [files/file.c] [files/directory.c]
Use Win32 kernel objects and handles for file handles.
Unified SearchPath() and OpenFile().
* [loader/builtin.c]
Moved to if1632/ directory.
* [tools/build.c] [debugger/*] [miscemu/*]
Win16 register functions now receive the same CONTEXT * structure
as Win32 functions.
* [include/sigcontext.h] [miscemu/instr.c]
Added new macros to get register values from the SIGCONTEXT
structure (only used for instruction emulation now).
* [scheduler/process.c] [scheduler/thread.c] (New files)
Allocate process and thread structures.
* [scheduler/process.c] [win32/k32obj.c]
Added Win32 kernel objects and handles management.
* [loader/task.c]
Create a Win32 process and thread for every Win16 task.
* [misc/commdlg.c] [misc/shell.c] [windows/msgbox.c]
Built-in resources are now in Win32 format. This also avoids
16-bit callbacks for built-in dialogs.
* [misc/lzexpand.c]
Differentiate between 16-bit and 32-bit file handles.
* [miscemu/int*.c]
Moved all int emulation to msdos/ directory.
* [msdos/*]
New directory msdos/ contains all MS-DOS emulation code that can
also be used for Winelib; this should enable Winelib apps to use
DOS3Call and related functions.
* [rc/winerc.c]
A few bug fixes for Win32 resource format.
* [windows/winpos.c]
Hack in WINPOS_ReorderOwnerPopups() to avoid X crashed (still not
right though).
Sun Dec 29 17:47:55 1996 O. Flebbe <flebbe@science-computing.uni-tuebingen.de>
* [loader/pe_image.c]
Make sure BSS of a PE_Image is zero.
Sat Dec 28 22:15:34 1996 Alex Korobka <alex@trantor.pharm.sunysb.edu>
* [windows/scroll.c]
ScrollWindowEx() rewrite, ScrollDC() fix.
* [windows/nonclient.c] [controls/menu.c]
Fixed Alt-Space crashes in dialogs.
* [windows/event.c] [windows/message.c]
Some changes in mouse message generation.
Thu Dec 26 09:25:24 1996 Philippe De Muyter <phdm@info.ucl.ac.be>
* [debugger/stabs.c]
Dummy DEBUG_ReadExecutableDbgInfo provided for !__ELF__ case.
Tue Dec 24 00:59:05 MET 1996 Martin Buck <martin-2.buck@student.uni-ulm.de>
* [windows/event.c]
Changed XK_Page_{Up,Down} to XK_{Prior,Next} for X11R5
compatibility.
