Changed: ILGetSize(), _ILIsDesktop(), PathCombine(). * [include/shlobj.h] New SHLGUID's New structures: DVTARGETDEVICE32, STGMEDIUM32, FORMATETC32, CLIPFORMAT32. New interfaces: IEnumFORMATETC, IDataObject, ICommDlgBrowser IDockingWindowFrame, IServiceProvider. * [dlls/shell32/folders.c] Stubs for IShellLink. * [loader/resource.c] Small fixes. * [misc/crtdll.c][relay32/crtdll.spec] New __dllonexit(). * [windows/message.c] SendNotifyMessageA, SendMessageCallBack32A half implemented. * [controls/edit.c] EDIT_WM_SetText set EF_UPDATE flag not for ES_MULTILINE. * [files/file.c] Handling of fileposition fixed. Fri Sep 25 18:13:30 1998 Patrik Stridvall <ps@leissner.se> * [include/windows.h] [include/wintypes.h] [ole/ole2nls.h] [relay32/kernel32.spec] Implemented EnumDateFormats and EnumTimeFormats. Only adds US English support. * [Makefile.in] [configure.in] [dlls/Makefile.in] [dlls/psapi/Makefile.in] [dlls/psapi/psapi_main.c] New files to implement stubs for PSAPI.DLL (NT only). * [relay32/Makefile.in] [relay32/builtin32.c] [relay32/psapi.spec] New spec file for PSAPI.DLL (NT only). * [scheduler/handle.c] HANDLE_GetObjPtr should only interpret the pseudo handles as the current thread or the current process if a thread or a process is requested. * [include/winversion.h] [misc/version.c] Adds the global function VERSION_GetVersion() so functions can have different behavior depending on the -winver flag. * [include/oledlg.h] [ole/oledlg.c] Minor fixes. * [windows/winproc.c] Minor changes. * [include/imm.h] [misc/imm.c] Now returns correct values under both Windows 95 and NT 4.0. Thu Sep 24 22:11:44 1998 Kristian Nielsen <kristian.nielsen@risoe.dk> * [configure.in] [include/acconfig.h] [include/thread.h] [scheduler/sysdeps.c] Autoconfig test for non-reentrant libc. Wed Sep 23 19:52:12 1998 Matthew Becker <mbecker@glasscity.net> * [*/*.c] Miscellaneous documentation updates and debugging output standardizations. * [objects/clipping.c] Added ExtSelectClipRgn. Wed Sep 23 00:03:28 EDT 1998 Pete Ratzlaff <pratzlaff@cfa.harvard.edu> * [include/windows.h] [if1632/user.spec] [relay32/user32.spec] [windows/keyboard.c] Added, marginally implemented, GetKeyboardLayoutName(). Only returns US English keyboard name. Tue Sep 22 16:32:41 1998 Marcel Baur <mbaur@iiic.ethz.ch> * [programs/control/*] New Winelib application. Mon Sep 21 00:29:18 1998 Peter Hunnisett <hunnise@nortel.ca> * [include/dplay.h][multimedia/dplay.c][ole/compobj.c] Added all DirectPlayLobby interfaces and enhanced DirectPlay and DirectPlayLobby support. Still not all that much. Useful enough if you just need to start a program, don't try any real dplay/lobby stuff. * [documentation/status/directplay] Added a very little bit. * [graphics/ddraw.c] - Call to SetWindowLong32A wasn't working because there was no memory set aside when the window class was registered. - Fixed some xlib reference counting and change the behaviour of DirectDrawSurface3_SetPalette to mimic observed behaviour (palette is associated will all backbuffers) - Also stored all palette colour fields and spit back our saved colour fields rather than query X for them. - Added plenty of AddRef and Release traces. - Added Xlib support for using -desktop option. - Fixed Xlib message handling. Messages weren't being passed to the application. Fixes mouse movements in some xlib DDraw games. - Added a few stubs. * [windows/win.c][include/winerror.h] Fixed up some error handling in WIN_SetWindowLong. SetLastError wasn't being used. Could cause problems with 0 return codes. Added new error in winerror (1400). * [AUTHORS] [include/authors.h] Added myself as a Wine author. Sun Sep 20 21:22:44 1998 Alexander Larsson <alla@lysator.liu.se> * [loader/module.c] Changed GetModuleFileName32A so that is returns the long version of the filename. Note that just the name is long, not the directories. Sat Sep 19 20:05:30 1998 Per Ångström <pang@mind.nu> * [controls/menu.c] Made a couple of fixes to make life easier for applications that alter their menus at runtime. * [windows/defdlg.c] Removed the cast of the return value from dialog procedures to a 16-bit bool. The return value needs to retain all its 32 bits, since it is not always a bool, such as when responding to the WM_NCHITTEST message. Fri Sep 18 11:30:38 1998 Sergey Turchanov <turchanov@usa.net> * [loader/resource.c] Fixed very funny bug (though gravely affecting further excecution) with FindResource[Ex]32 functions. * [include/multimon.h] [windows/multimon.c] [relay32/user32.spec] [include/windows.h] [windows/sysmetrics.c] Default implementation for Multimonitor API. * [include/windows.h] [windows/winpos.c] Fixed incorrect declaration (and behaviour) of GetWindowRect32. Wed Sep 16 10:21:15 1998 Gerard Patel <G.Patel@Wanadoo.fr> * [controls/edit.c] Fixed EDIT_EM_GetLine to use correctly length of lines. Tue Sep 15 20:40:16 1998 Eric Kohl <ekohl@abo.rhein-zeitung.de> * [misc/tweak.c][include/tweak.h][controls/menu.c] Replaced the tweak graphic routines by calls to DrawEdge32(). * [misc/tweak.c][include/tweak.h][documentation/win95look] [wine.ini][*/*] Changed "look and feel" selection. Allows Win3.1, Win95 and Win98 (no GUI code implemented) look and feel. * [dlls/comctl32/header.c][include/header.h][include/commctrl.h] Started callback item support and did some minor improvements. * [dlls/comctl32/imagelist.c] Fixed bug in transparent image display. ImageList_GetIcon is still buggy :-( * [dlls/comctl32/toolbar.c] Fixed button drawing (partial hack). * [dlls/comctl32/commctrl.c] Fixed MenuHelp(). * [controls/button.c] Added 3d effect for groupbox. * [windows/msgbox.c] Added font support for message boxes. * [windows/nonclient.c] Fixed window moving bug. * [dlls/comctl32/*.c] Various improvements. * [dlls/comctl32/listview.c][dlls/comctl32/rebar.c] [include/commctrl.h] More messages. * [windows/syscolor.c][include/windows.h] Introduced new Win98 system colors. Tue Sep 15 18:29:45 1998 Wesley Filardo <eightknots@aol.com> * [files/profile.c] Added support in PROFILE_LoadWineIni for -config option * [misc/main.c] [include/options.h] Added -config option. Tue Sep 15 18:22:26 1998 Petter Reinholdtsen <pere@td.org.uit.no> * [documentation/Makefile.in] Make sure directory exists before installing into it. Tue Sep 15 01:47:33 1998 Pablo Saratxaga <pablo.sarachaga@ping.be> * [ole/nls/*] [ole/ole2nls.c] [include/winnls.h] Fixed a few errors and completed some NLS files. Mon Sep 14 01:23:45 1998 Joseph Pranevich <knight@baltimore.wwaves.com> * [include/miscemu.h] [msdos/interrupts.c] Removed a compilation warning, added INT 25 to the list of interrupts callable from DOS applications, added a debug message when unsupported interrupts are used. Sun Sep 13 19:55:22 1998 Lawson Whitney <lawson_whitney@juno.com> * [if1632/relay.c] CallProcEx32W should not reverse arguments. Sun Aug 17 21:18:12 1998 Eric Pouech <eric.pouech@lemel.fr> * [multimedia/midi.c] [multimedia/init.c] [multimedia/mmsys.c] [include/multimedia.h] [include/mmsystem.h] [multimedia/Makefile.in] [multimedia/midipatch.c] [if1632/multimedia.spec] Made MIDI input and output functional on OSS capable systems. * [multimedia/timer.c] Changes to trigger callbacks at the accurate pace even when fake timers are used.
