Release 960811
Sun Aug 11 13:00:20 1996 Alexandre Julliard <julliard@lrc.epfl.ch>
* [configure.in] [include/acconfig.h] [tools/build.c]
Added check for underscore on external symbols.
* [memory/selector.c] [memory/global.c]
Fixed FreeSelector() to free only one selector.
Added SELECTOR_FreeBlock() to free an array of selectors.
* [objects/color.c]
Fixed a bug in COLOR_ToLogical() that caused GetPixel() to fail on
hi-color displays.
* [tools/build.c] [if1632/crtdll.spec]
Added 'extern' type, used for external variables or functions.
* [windows/winpos.c]
Allow de-activating a window in WINPOS_ChangeActiveWindow().
* [windows/winproc.c]
Added 32-to-16 translation for button messages.
Fixed WINPROC_GetPtr() to avoid crashes on 32-bit procedures that
happen to be valid SEGPTRs.
Sat Aug 10 18:22:25 1996 Albrecht Kleine <kleine@ak.sax.de>
* [windows/message.c]
Removed a FIXME in MSG_PeekHardwareMsg(): produces correct
data for the JOURNALRECORD-hook (using EVENTMSG16 structure).
* [if1632/gdi.spec] [include/windows.h] [objects/metafile.c]
Introduced undocumented API function IsValidMetaFile(), plus a
minor fix in last patch of CopyMetaFile().
* [objects/gdiobj.c]
Removed a FIXME in IsGDIObject(): added magic word check.
Sun Aug 10 18:10:10 1996 Bruce Milner <Bruce.Milner@genetics.utah.edu>
* [controls/statuswin.c]
First pass at implementing the StatusWindow class.
* [include/commctrl.h]
Header file for common controls.
* [controls/widgets.c]
Added InitCommonControls().
* [if1632/comctl32.spec]
Add DrawStatusTextA, CreateStatusWindowA, InitCommonControls.
* [win32/findfile.c] [if1632/kernel32.spec]
Add FindNextFile32A, FindClose.
Modified FindFirstFile32A so it works with FindNextFile32A.
* [include/winbase.h]
Fixed WIN32_FIND_DATA structure member names.
Sat Aug 10 09:00:00 1996 Alex Korobka <alex@phm30.pharm.sunysb.edu>
* [windows/scroll.c]
Changed scrolling routines to benefit from DCE code update.
Thu Aug 8 18:05:09 1996 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de>
* [files/file.c]
SearchPath* could get NULL for lastpart argument.
* [if1632/build-spec.txt] [documentation/debugging]
Varargs documentation added, debugging hints updated.
* [if1632/crtdll.spec][misc/crtdll.c][misc/Makefile.in]
Started to implement CRTDLL.
* [if1632/wsock32.spec]
Some thunks to standard libc functions (structures have the same
elements, but perhaps wrong offset due to packing).
* [include/kernel32.h][include/windows.h][win32/*.c][loader/main.c]
Merged kernel32.h into windows.h.
* [misc/lstr.c]
Enhanced FormatMessage().
* [misc/main.c] [if1632/kernel.spec] [include/windows.h]
GetVersion() updated to new naming standard.
Changed language handling to support language ids.
* [misc/shell.c]
Enhanced FindExecutable, so it finds files in the search path too.
* [win32/environment.c]
GetCommandLine* updated.
* [loader/resource.c] [loader/pe_resource.c]
FindResourceEx32* added.
Loading of messagetables added.
Language handling now uses Wine default language id.
