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.
