Sun Jul 28 17:57:19 1996 Alexandre Julliard <julliard@lrc.epfl.ch> * [loader/task.c] [include/task.h] Implemented SwitchStackTo()/SwitchStackBack(). * [include/wintypes.h] [loader/main.c] Added __winelib variable to distinguish between emulator and library at run-time. Later on, this should avoid some recompilations when building Winelib. * [windows/property.c] Implemented Win32 functions for window properties. Fri Jul 26 18:00:00 1996 Alex Korobka <alex@phm30.pharm.sunysb.edu> * [controls/listbox.c] Implemented LBS_SORT style, WM_COMPAREITEM, and WM_DELETEITEM messages. * [controls/menu.c] Call TranslateMessage() to enable shortcuts (on WM_CHAR). * [include/cursoricon.h] Moved #pragma pack(1) back to where it belongs. * [objects/palette.c] RealizeDefaultPalette() maps to system colors only. Do not broadcast palette notifications when in TrueColor. * [objects/color.c] [include/palette.h] Miscellaneous optimizations. Had to fix several "improvements" made to my patch for previous release. * [objects/dib.c] Reverse dib bits order for 24-bit SetDIBits(). * [objects/dc.c] GetDeviceCaps() does not return RC_PALETTE when in TrueColor. * [windows/scroll.c] Scroll update region too. * [windows/message.c] Include QS_MOUSE into the event mask for nonclient mouse message filter. Fixes problems with Word 6 freezing when mouse hits nonclient area. * [windows/win.c] Allow top-level windows to be linked as HWND_TOP in CreateWindow(). * [windows/winpos.c] [windows/mdi.c] Attempt to fix control menu duplication. Fri Jul 26 09:49:35 1996 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de> * [files/drive.c] GetDriveType32A(): return value for CDROM fixed. * [files/file.c] SearchPath* added. * [if1632/gdi32.spec] [objects/brush.c] SetBrushOrgEx() added. * [loader/pe_resource.c] If even loading the default entry fails, we just use the first entry from the resource directory. [loader/task.c] SetSigHandler() stub added, Paradox 4.5 now starts up. * [misc/comm.c] [include/windows.h] [if1632/kernel32.spec] COMM functions updated to win32, not complete. * [misc/lstr.c] FormatMessageA partially implemented. * [include/miscemu.h] [memory/selector.c] [memory/global.c] [miscemu/dosmem.c] DOS memory handling changed: 1MB preallocated block, real-mode segment handling possible, SetSelectorBase into lower physical 1MB possible. * [miscemu/dpmi.c] Real-mode segments changed, real-mode int 21,ax=6506 added. AX=0x0303 added. * [multimedia/time.c] Fixed bug in killTimer. * [objects/bitmap.c] LoadImageA partially implemented. Wed Jul 24 18:20:24 1996 Albrecht Kleine <kleine@ak.sax.de> * [include/dde_mem.h][include/dde_proc.h] [ipc/dde_atom.c][ipc/dde_proc.c][windows/message.c] [ipc/generic_hash.h][library/miscstubs.c] Changes for error free compilation using "--with-ipc": replaced some names with *16-equivalent (e.g. MSG to MSG16), modified prototype of function DDE_GlobalFree() . * [objects/palette.c] Added check for metafile-DC in GDISelectPalette(), GDIRealizePalette(),RealizeDefaultPalette() and IsDCCurrentPalette(). Tue Jul 23 22:46:53 1996 Andrew Lewycky <plewycky@oise.utoronto.ca> * [controls/edit.c] EDIT_WM_Create: Don't EDIT_EM_ReplaceSel if created with lParam = "", fixes Winhelp. * [windows/dialog.c] DIALOG_CreateIndirect: Initialise dlgProc before creating children.
