Fri Sep 11 13:14:35 1998  Andreas Mohr <100.30936@germany.net>

	* [files/file.c] [include/file.h]
	Fixed SetFilePointer to allow negative positions as in DOS.

	* [graphics/ddraw.c]
	Added some methods to IDirect3D.

	* [ole/compobj.c] [if1632/compobj.spec]
	Added/implemented CoCreateStandardMalloc16,
	CoGetClassObject, CoCreateInstance,
	LookupETask, SetETask, CoGetState16.

	* [loader/task.c]
	MakeProcInstance: return 0 if func == NULL.

	* [*/*] [tools/winapi-check]
	Added zillions of missing WINAPI's and __cdecl's.
	(oops, several caused by myself)
	Wrote script for automated checking.

	* [if1632/compobj.spec]
	Many stub names.

	* [misc/ddeml.c] [ole/compobj.c]
	Some stubs.

Tue Sep  9 21:36:48 1998  Anders Carlsson <anders.carlsson@linux.nu>

	* [dlls/comctl32/Makefile.in] [dlls/comctl32/commctrl.c]
	  [dlls/comctl32/tab.c] [include/commctrl.h] [include/tab.h]
        Added preliminary tab control support.

Sat Sep  5 16:27:20 1998  Huw D M Davies <daviesh@abacus.physics.ox.ac.uk>

	* [graphics/psdrv/*]
	More changes to the PostScript driver:
	Implemented pens and solid brushes.
	Colour/greyscale for fonts, pens and brushes.
	To get coloured output you need to have *ColorDevice set to true
	in your PPD, otherwise you'll get greyscale.
	Landscape mode now works, as does non-A4 page sizes.
	Encoding of fonts to ANSI is better, Symbol works again.

	* [objects/dc.c] [include/gdi.h] [*/*]
	Moved dc->w.{text,background}Pixel to X11DRV_PDEVICE where they
	belong.

Sat Sep  5 05:12:09 1998  Ove Kaaven <ovek@arcticnet.no>

	* [include/dosexe.h] [include/miscemu.h] [include/msdos.h]
	  [loader/dos/dosvm.c] [loader/dos/module.c] [msdos/dpmi.c]
	  [msdos/int2f.c] [msdos/interrupts.c]
	Fixed portability. Adapted some code to make it easier to
	integrate the DOS subsystem with the DPMI subsystem, made
	the DPMI simulated real-mode interrupts be handled the V86
	way. Added support for .COM files. Made int2f DPMI check
	fail, to avoid pkunzip crashing in attempting to use DPMI.
	Generally moved stuff around a little.
	It is now technically possible to load several DOS programs
	into the same memory space. Not tested, though.

Fri Sep  4 21:40:45 1998  Marcus Meissner <marcus@jet.franken.de>

	* [if1632/kernel.spec]
	Changed 500-53x stubnames accordingly to nt3.51 krnl386.exe.

	* [win32/except.c]
	Fixed one bad program behaviour, (deleting SEH while in 
	first walk). RtlUnwind is broken too I think (it should unwind
	on success, not while walking the exception chain).

	* [ole/ole2nls.c]
	Get*DefaultLCID  returns 0x400|id. expected by one application.

	* [if1632/snoop.c]
	Handle non-standard SP returns more graceful.

	* [windows/class.c]
	hinstances are mostly irrelevant for win32.

	* [memory/string.c] [misc/registry.c]
	lstrcmpi32W: use toupper for characters < 0x100. (speedup hack
	for registry.c)
	Some small speedup hacks for registry.c

Thu Sep  3 20:40:16 1998  Eric Kohl <ekohl@abo.rhein-zeitung.de>

	  [dlls/comctl32/Makefile.in]
	Created dlls/comctl32 and moved the common controls stuff to it.

	Removed COMCTL32_DllGetVersion. The fixed function is part
	of the common controls stuff.

	* [dlls/comctl32/*.c][include/commctrl.h]
	Added structure size tests.

	* [dlls/comctl32/toolbar.c]

	* [dlls/comctl32/animate.c][include/animate.h]
	  [dlls/comctl32/comboex.c][include/comboex.h]
	  [dlls/comctl32/hotkey.c][include/hotkey.h]

	Listview control dummies.

	* [dlls/comctl32/tooltips.c]
	Fixed a display bug and font selection.

	  [relay32/msnet32.spec] [relay32/oledlg.spec]
	Added new spec files for IMM32.DLL, MSNET32.DLL, OLEDLG.DLL.

	* [misc/Makefile.in] [misc/imm.c] [include/imm.h]
	Added news files for implementation of IMM32.DLL. 
	All functions return 0 as is correct for all Western Languages.

	existent drive.

	* [msdos/int21.c]
	INT21_FindFirstFCB: check drive validity to prevent oops.

	* [win32/file.c]
	CreateFile32A: duplicate STD_{INPUT,OUTPUT}_HANDLE.

	* [files/dos_fs.c]
	Make DOSFS_OpenDir treat "" as "/".
	DOSFS_OpenDevice: duplicate STD_{INPUT,OUTPUT}_HANDLE.

	* [windows/dialog.c]
	GetNextDlgTabItem32: use last/first item instead of first/last

Sat Aug 29 02:46:32 1998  Adrian Harvey <adrian@select.com.au>

	* [include/process.h] [include/process.c]
	Renamed PROCESS_SELF to CURRENT_PROCESS_PSEUDOHANDLE in line
	with thread constant, and Win32 documentation (which calls it
	a pseudohandle.)  Made GetCurrentProcess actually use this
	constant instead of the value.

	* [include/process.h] [include/thread.h] [scheduler/thread.c]
	  [scheduler/process.c] [scheduler/handle.c]
	Modify HANDLE_GetObjPtr to understand about
	CURRENT_THREAD_PSEUDOHANDLE and CURRENT_PROCESS_PSEUDOHANDLE.
	This allows DuplicateHandle to do the correct thing with these
	handles.  Removed now duplicate functionality from THREAD_GetPtr
	and PROCESS_GetPtr.

	* [loader/ne/segment.c]
	Fixed two places where HFILE32s were being created and passed to
	16-bit code. This should unbreak NE self-loading code.
	Added two casts to remove compile time warnings.

Fri Aug 28 21:04:13 1998  Joseph Pranevich <knight@baltimore.wwaves.com>

	* [msdos/dosmem.c] [msdos/int2f.c]
	Added beginnings of DOS error table.

	* [msdos/int1a.c]
	Stub for subfunction 0xb0.

	* [msdos/int10.c] [loader/dos/dosvm.c]
	INT 10 support completely rewritten and lots of debugging
	added. Now, DOS apps that use INT 10 to write to the screen will
	work. (Beyond Zork does, at least. Somewhat.)

	* [include/miscemu.h] [msdos/dosmem.c] [msdos/int21.c]
	Another shot at getting MS's generic error message facility
	right.

	* [msdos/int21.c]
	Command.Com wanted to set its own PSP address. I let it.

Wed Aug 26 12:26:20 1998  Matthew Toseland <Matthew.Toseland@btinternet.com>

	* [include/file.h] [misc/lzexpand.c]
	Fixed LZCopy16 by fixing HFILE16/HFILE32 convertor macros so don't
	convert lzw handles.

Tue Aug 25 22:22:55 1998  Uwe Bonnes <bon@elektron.ikp.physik.tu-darmstadt.de>

	* [misc/registry.c]
	In RegEnumvalue, ivalue == 0 is a legal request and should
	return the first entry.

	* [msdos/int21.c]
	Add handling for Int21-48/49 in Win16. Makes blinker demo work.

	* [windows/winproc.c]
	Add Msg32A<->Msg32W translation for LB_ADDSTRING.

Tue Aug 25 21:03:31 1998  Kristian Nielsen  <kristian.nielsen@risoe.dk>

	* [windows/win.c]
	Fix for SetParent(): MS Windows 3.11 does not clear the WS_CHILD
	flag when a child window is reparented to the desktop window.

Mon Aug 24 20:55:22 1998  Berend Reitsma <berend at asset-control dot com>

	* [controls/menu.c]
	Menus created with SetMenuItemInfo and InsertMenuItem should
	work now.

Sun Aug 23 23:23:23 1998  Alex Korobka <korobka@ams.sunysb.edu>

	* [controls/combo.c]
	Added CB_GETITEMHEIGHT.

	* [windows/winpos.c] 
	WM_NCHITTEST, SWP_FRAMECHANGED bugfixes.

Sat Aug 22 21:15:29 1998 Alex Priem <alexp@sci.kun.nl>

	* [files/profile.c] [include/windows.h]
	Added GetPrivateProfileSectionNames[AW],GetPrivateProfileSectionW,
	GetPrivateProfileStructW, GetProfileSectionW,
	WriteProfileSection[AW], WritePrivateProfileStructW.

DOS treats the first 5 file handles as special cases. They map directly
to stdin, stdout, stderr, stdaux and stdprn. Windows 16 inherits this
behavoir, and in fact, win16 handles are interchangable with DOS handles.
Some nasty windows programs even do this!
Windows32 issues file handles starting from 1, on the grounds that
most GUI processes don't need a stdin, out, etc.
The wine handle code is implemented in the Win32 style, and the Win16
functions use two macros to convert to and from the two types.
The macros are defined in file.h as follows.:
#define HFILE16_TO_HFILE32(handle) \
(((handle)==0) ? GetStdHandle(STD_INPUT_HANDLE) : \
((handle)==1) ? GetStdHandle(STD_OUTPUT_HANDLE) : \
((handle)==2) ? GetStdHandle(STD_ERROR_HANDLE) : \
((handle)>0x400) ? handle : \
(handle)-5)
#define HFILE32_TO_HFILE16(handle) ({ HFILE32 hnd=handle; \
((hnd==HFILE_ERROR32) ? HFILE_ERROR16 : \
((handle>0x400) ? handle : \
(HFILE16)hnd+5); })
WARNING: be careful not to use the macro HFILE16_TO_HFILE32 on
functions with side-effects, as it will cause them to be evaluated
several times. This could be considered a bug, but the use of this
macro is limited enough not to need a rewrite.
NOTE: The 0x400 special case above deals with LZW filehandles (see
misc/lzexpand.c).
