Sun Apr 28 14:32:43 1996 Alexandre Julliard <julliard@lrc.epfl.ch> * [Makefile.in] Subdir memory is now also compiled for Winelib, in order to get the Win32 heap functions. * [if1632/Makefile.in] Renamed winprocs and winprocs32 to wprocs and wprocs32 to avoid DLL names > 8 characters. * [loader/builtin.c] (New file) Grouped all built-in DLLs code in a single file. * [memory/global.c] Use the Win32 heap code instead of malloc() to allocate linear memory. This will help test the heap code. * [memory/local.c] Fixed FreeSelector() to clear DS and ES correctly for huge blocks. * [tools/build.c] [if1632/relay.c] Removed 'id' directive in spec files. For relay debugging, the DLL entry point is now computed from the CS:IP entry point address. Added 'heap' directive to specifiy a local heap for the DLL. USER and GDI heap are now created this way. * [windows/class.c] [include/class.h] Changed the class structure to use pointers instead of handles. Changed Get/SetClassWord/Long to use a switch statement; this allows changing the layout of the CLASS structure. * [windows/win.c] [include/win.h] Use a CLASS * instead of a handle for the window class. Sat Apr 27 18:10:11 Martin von Loewis <loewis@informatik.hu-berlin.de> * [if1632/kernel32.spec] [memory/global.c] [win32/memory.c] [win32/process.c] GetProcessAffinityMask,GlobalLock,IsBadReadPtr,IsBadWritePtr, LocalLock,SetThreadAffinityMask: new relays. * [win32/cursoricon32.c] Return same handle if a cursor is loaded multiple times. Sat Apr 27 15:13:37 1996 Bang Jun Young <bangjy@nownuri.nowcom.co.kr> * [resources/sysres_Ko.rc] Added support for Korean [Ko] language. Fri Apr 26 00:49:05 1996 Huw D. M. Davies <h.davies1@physics.oxford.ac.uk> * [objects/dc.c] [objects/font.c] Fixed problem with SaveDC()/RestoreDC() and font cache 'used' count. * [objects/metafile.c] [objects/dcvalues.c] Fixed broken SetTextAlign() on metafiles. * [objects/metafile.c] Delete objects in handle table at end of PlayMetaFile(). Wed Apr 24 19:21:01 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de> * [if1632/ver.spec] [misc/ver.c] [include/ver.h] (New files) VER.DLL (partially) implemented (VerFindFile,VerInstallFile) [If it doesn't work for you, use -dll -ver and report it to me] * [if1632/user32.spec] [if1632/kernel32.spec] [if1632/shell.spec] [if1632/shell32.spec] [misc/ole2nls.c] [windows/message.c] [windows/graphics.c] Simple win32 functions, where we can just use the win16 counterpart. Misc. stubs. * [misc/lstr.c] Someone reported a _lstrlen(NULL). NULL is a valid argument. Fixed. * [misc/registry.c] Some alloclens were off by 1, one double fclose() fixed. Requesting value 0 of a key with no values returns an error (should we always return a made up value NULL? what does win3.1?) Tue Apr 23 17:00:00 1996 Alex Korobka <alex@phm30.pharm.sunysb.edu> * [misc/shell.c] Implemented FindEnvironmentString(), DoEnvironmentSubst(), ExtractIcon(), InternalExtractIcon() and ExtractAssociatedIcon(). * [misc/user.c] Do extensive cleanup on application exit. * [windows/hook.c] [windows/win.c] [windows/class.c] Added miscellaneous cleanup routines. * [controls/menu.c] More efficient popup menu window handling. Mon Apr 22 21:35:22 1996 Albrecht Kleine <kleine@ak.sax.de> * [include/windows.h][objects/oembitmap.c][include/bitmaps/obm_trtype] Added "TT-bitmap" for later usage in a ChooseFont() ownerdraw combobox.
