Sat Apr 29 20:42:01 1995 Alexandre Julliard (julliard@sunsite.unc.edu)
* [controls/static.c]
Fixed painting of SS_*FRAME controls.
* [if1632/callback.c]
Pass the window instance as DS to the 16-bit window procedure.
Rewrote Catch() and Throw() to make them work with multiple tasks.
* [loader/main.c]
New function MAIN_Init() to perform initializations before the
first task is started instead of doing them in InitApp().
Temporary hack to command-line parsing to load one program per
command-line argument, to make testing task-switching easier.
* [loader/*.c]
Reimplemented modules to use a Windows-compatible layout and to
allow multiple tasks and multiple module instances. Not really
finished yet.
* [loader/task.c] [misc/exec.c]
Reimplemented tasks to use a common address space, and implemented
preliminary task-switching capabilities.
* [memory/global.c]
Fixed bug in GlobalNext().
* [misc/main.c]
Updated the list of contributors. Let me know if I forgot someone.
* [miscemu/int21.c]
Use one DTA per task instead of a global one.
* [objects/bitblt.c]
Fixed bug in BitBlt() that could cause BadMatch errors.
* [tools/build.c]
Added new function type 'stub', that makes possible to export an
unimplemented function by name as well as by ordinal. This will
avoid loading errors for unimplemented functions.
Generate an in-memory module layout for built-in DLLs so that the
same code can be used for built-in and loaded modules.
Changed relay code to make it unnecessary to save the value of the
BP register.
* [windows/message.c]
Implemented multiple message queues and preliminary task-switching
capabilities. Inter-task SendMessage() calls are not implemented
yet and will probably cause crashes if used.
* [windows/property.c]
Reimplemented properties and allocate them on the USER heap.
* [windows/win.c]
Fixed bug in SetWindowWord().
Reimplemented EnumWindows() and EnumTaskWindows().
Tue Apr 18 09:48:38 1995 Bernd Schmidt <crux@pool.informatik.rwth-aachen.de>
* [misc/main.c]
GetSystemParametersInfo(): Additional action SPI_GETICONTITLEFONT.
* [loader/resource.c]
Removed the check for NE_SEGFLAGS_EXECUTEONLY, since it broke
control.exe.
Fixed icon loading.
* [objects/font.c] [include/windows.h]
Fixed a bug in InitFontsList() and worked on the EnumFonts()
functions to make them comprehensible.
* [controls/button.c]
Fixed my previous patch to handle LBUTTONUP messages.
Fri Apr 14 11:41:28 1995 Cameron Heide (heide@ee.ualberta.ca)
* [misc/network.c, misc/dos_fs.c]
Implemented WNetGetConnection. All that is currently
supported are drives, for which the remote name is simply
the redirected UNIX directory name.
* [miscemu/int2?.c]
More drive number validity checking.
Wed Apr 12 11:28:37 1995 Bernd Schmidt <crux@pool.informatik.rwth-aachen.de>
* [controls/listbox.c]
Oops, my previous change to ListBoxDirectory broke the Borland
file open dialog. Fixed.
Mon Apr 10 23:17:12 1995 Martin von Loewis <loewis@informatik.hu-berlin.de>
* [if1632/ole2nls.spec] [misc/ole2nls.c] [misc/Imakefile]
New file ole2nls.c. Added stubs for GetUserDefaultLCID,
GetSystemDefaultLCID, GetUserDefaultLangID, GetSystemDefaultLangID.
Mon Apr 10 10:05:18 1995 Bernd Schmidt <crux@pool.informatik.rwth-aachen.de>
* [memory/global.c] [memory/local.c] [include/windows.h]
GlobalReAlloc(): If GMEM_MODIFY is set, don't resize the block.
LocalReAlloc(): Same for LMEM_MODIFY.
* [controls/listbox.c]
Fixed a bug in ListBoxDirectory that prevented commdlg from working.
Check for errors in some more places.
* [if1632/gdi.spec] [if1632/user.spec]
16 bit callback functions should be passed as segptrs.
* [include/dlls.h] [loader/ne_image.c] [loader/selector.c]
[loader/library.c]
Prevent a DLL from being initialized twice (Borlands Resource
Workshop used to do this).
Provide an additional flag for each w_file that indicates whether
it's an EXE or a DLL, for combinations like pbrush.exe/.dll.
* [controls/button.c]
Handle LBUTTONUP messages even if the button no longer has the
capture (for WinHelp).
* [include/wintypes.h]
FARPROC is now a segptr for the emulator and a function
pointer for the library.
* [misc/commdlg.c] [misc/commdlg.h]
Cleaned the file dialogs up a little. They now work reasonably well,
although there are still some problems (e.g. files are initially
invisible).
* [windows/class.c] [if1632/user.spec] [include/windows.h]
GetClassInfo() must take a segptr, as it checks whether the
highword is zero.
GetClassName() called the wrong atom function. No surprise it didn't
find anything.
* [misc/lstr.c]
AnsiToOem() and OemToAnsi() didn't terminate the strings. Fixed.
Removed some warnings.
* [if1632/relay.c] [if1632/ddeml.spec] [include/dlls.h]
New spec file for the 3.1 DDEML DDL.
* [controls/menu.c]
Small fix to ChangeMenu - mask out the obsolete flags
(MF_APPEND == MF_OWNERDRAW, this led to problems). It also had
problems with the MF_BYPOSITION flag.
* [windows/message.c]
SendMessage(): call the WH_CALLWNDPROC hook function. This is rather
ugly, I'm afraid. Windows probably passes a pointer to the 16 bit
stack for speed reasons.
* [windows/hook.c] [include/windows.h]
Set/HookWindowsHook() shouldn't just call their *Ex counterparts, as
they have slightly different semantics.
MS Hearts now works somewhat, if you disable the new builtin DDEML.
The graphics are completely messed up, though.
Sun Mar 19 16:30:20 1995 Alexandre Julliard (julliard@sunsite.unc.edu)
* [*/*]
Implemented a new memory mapping scheme. There's no longer a
one-to-one mapping between 16-bit and 32-bit pointers. Please see
file DEVELOPERS-HINTS for technical details.
* [controls/scroll.c]
Fixed bug when dragging mouse in horizontal scrollbars.
* [tools/build.c] [if1632/*.spec]
Removed support for C callback functions and for re-ordering
of the 32-bit arguments, as these were never used. This should
allow a more efficient callback scheme to be implemented.
* [if1632/olecli.spec]
Reduced the number of entries to make the 16-bit code fit in 64k.
This limitation will soon be removed.
* [loader/ldt.c]
Rewrote LDT manipulation functions and implemented LDT_GetEntry().
* [memory/global.c]
Rewrote Global*() routines to use the new selector allocation
mechanism.
* [memory/local.c]
Rewrote local heap handling to use a Windows-compatible layout
(not really finished yet).
Implemented TOOLHELP heap-walking routines.
* [memory/selector.c]
Implemented LDT manipulation API functions.
Tue Mar 14 19:50:28 EST 1995 William Magro (wmagro@tc.cornell.edu)
* [windows/defdlg.c]
Fixed problem where dialogs closed using the System menu
('Close' item or double click on close box) would
hang Wine.
Sun Mar 12 14:28:13 1995 Michael Patra <micky@marie.physik.TU-Berlin.DE>
* [controls/listbox.c]
Removed most of the statements for sending a notification message
ListBoxDirectory(), DlgDirSelect(), DlgDirList(): Improved the
code; Borland's standard file open dialog will work now.
* [misc/main.c], [misc/file.c], [miscemu/int21.c]
Added support for new command line option "-allowreadonly". If set
an attempt to open a read only file in write mode will be converted
to opening it read only (many programs try to open all files in
read/write mode even if they only intend to read it - this might
cause a few under problems under an unix-like environment where most
files are read only for a "normal" user)
* [loader/selector.c]
GetMemoryReference(): Added support for __AHIncr and __AHShift
* [misc/dos_fs.c]
DOS_SimplifyPath(): This routine simplifies path names ( e.g., it
will change "/usr///local/bin/../lib//a" to "/usr/local/lib/a" )
match(): rewritten
* [objects/text.c]
TEXT_NextLine(): Removed a bug in the handling of LF's
* [miscemu/int21.c]
GetFileDateTime(): Fixed. SetFileDateTime() is still broken.
Sat Mar 11 19:46:19 1995 Martin von Loewis <loewis@informatik.hu-berlin.de>
* [controls/menu.c]
ChangeMenu: defaults to MF_INSERT
InsertMenu: allow insertion even if position is one after last item
* [if1632/Imakefile] [if1632/compobj.spec] [if1632/relay.c]
[if1632/storage.spec] [include/dlls.h]
Added stubs for STORAGE.DLL and COMPOBJ.DLL
* [if1632/user.spec] [windows/message.c]
InSendMessage: new function
* [include/neexe.h][include/ne_image.c]
NE_FixupSegment: fixed handling of additive records
* [loader/selector.c]
GetEntryDLLName: return NULL instead of pointer to DLL.0 if not found
* [loader/signal.c]
win_fault: Enter debugger on SIGFPE, too
Wed Mar 1 21:47:42 1995 Cameron Heide (heide@ee.ualberta.ca)
* [miscemu/int*.c]
Various minor modifications to the clock tick counter,
FindFirst/FindNext funcs, and DPB handling.

* [objects/metafile.c]
Implemented GetMetafile().
Fixed bug in PlayMetaFile() when reading disc based metafile records.
Added META_POLYPOLYGON, META_DELETEOBJECT and META_EOF to
PlayMetaFileRecord().
Wed Nov 30 06:32:25 1994 Martin von Loewis (martin@cs.csufresno.edu)
* [Imakefile]
wine.sym: Remove gcc2_compiled and friends

Replace #ifdef DEBUG_XXX with if(debugging_xxx){
* [if1632/call.S]
CallToLibMain: New function
* [if1632/relay.c][include/options.h][misc/main.c]

* [objects/bitblt.c]
BitBlt(): BitBlt is now able to handle any raster operation. If
the request can't be passed to XWindows directly, it's quite
slow, though.
* [*/*.c]
[misc/main.c]
Improvements of the system for handling debug messages. Options are
now also loaded from /usr/lib/X11/app-defaults/Wine (insert
*debugoptions: +xxx there if you want to have turn messages xxx on).
* [controls/menu.c]
DestroyMenu(): The whole window won't be destroyed as a sideeffect
any longer.
* [misc/file.c]
OpenFile(): Fixed bug in searching in system/window-directory.
Sun Oct 30 12:25:53 1994 Jimmy Tirtawangsa <j0t2527@tam2000.tamu.edu>
* [include/windows.h]

Use pairs of foundry and family fontnames in X11 to correspond with
window's fonts.
Put font assignment ini wine.ini.
* [wine.ini]
Adding optional baudrate after port name in "serialports" section

* [misc/commdlg.c] New file.
* [include/commdlg.h] New file.
Begin of an emulated COMMDLG DLL, built-in for now.
(BTW, if you want to switch between built-in & 16bits CommDlg, only
thing you need to do is to put the real/dummy name in file relay.c)
* [controls/scroll.c]
* [controls/combo.c]
* [controls/listbox.c]
Few bug fixes and/or cosmetic.
* [misc/audio.c]

In DrawText(), the code to delete crlfs also removed multiple
consecutive newlines. Also, using DT_CALCRECT didn't return
the right height, and the width wasn't returned at all.
This caused MessageBoxes to be missing much of their text.
* [windows/scroll.c]
ScrollWindow[Ex] didn't work right with null LPRECT arguments.
Fri Oct 21 21:47:19 1994 Paul Falstad (pf@zoof.cts.com)
* [miscemu/int21.c]

Send WM_SYSCOMMAND to overlapped ancestor window,
not the receiver of WM_SYSKEYDOWN
Sat Oct 22 15:01:02 1994 Thomas Sandford <t.d.g.sandford@bradford.ac.uk>
* [controls/edit.c]
ClientWidth()/ClientHeight() macros: return 0 if size would
be negative
EDIT_StrLength(): takes unsigned char* instead of char*
* [controls/listbox.c]
ListBoxWndProc(): in "case WM_MOUSEMOVE" - set lphl at start of
case instead of in each place required (it was omitted in
some places causing problems!)
* [controls/menu.c]
MENU_CalcItemSize(): don't try to find size of a text item
if the pointer is NULL
* [include/heap.h]
added definition of HEAP_LocalInit()
* [include/msdos.h]
removed buggy pointer() macro (use SAFEMAKEPTR() from segmem.h
instead)
* [loader/selector.c]
IPCCopySelector(): added missing flags to shmget() call
? does this break linux - I added these flags in a previous
patch but they were missing in the corresponding release ?
* [loader/signal.c]
win_fault(): added missing definitions of i, dump for those
not running NetBSD or linux
* [misc/dos_fs.c]
DOS_GetCurrentDir(): made temp[] static so it can be safely
returned
* [miscemu/int21.c,int25.c,int26.c]
Changed all invocations of pointer() to SAFEMAKEPTR(). Included
segmem.h where necessary.
* [windows/dialog.c]
CreateDialogIndirectParam(): Changed HEAP_Init() call to
HEAP_LocalInit(), removed redundant variables
Sat Oct 22 00:29:41 MET 1994 Dag Asheim (dash@ifi.uio.no)

[misc/exec.c] [miscemu/int10.c] [miscemu/int21.c]
[objects/bitblt.c] [objects/metafile.c]
Rewritten more printf's to use the new debugging system, and
made wine less verbose per default. Use "-debugmsg +module"
to get (almost) the same behavior as before.
Sun Oct 16 13:29:07 1994 Alexandre Julliard (julliard@lamisun.epfl.ch)
* [controls/button.c]

Implemented default push button handling and DM_SETDEFID.
Implemented WM_NEXTDLGCTL.
* [windows/dialog.c]
Implemented default push button handling.

Sun Oct 16 12:21:52 1994 Michael Patra <micky@marie.physik.tu-berlin.d400.de>
* [include/debug.h]
[include/stddebug.h]
[*/*.c]
Rewritten all the calls to printf for displaying debug-information
(messages like "LoadImage: loading SOL (SOL.EXE)" etc.)
Added option "-debugmsg" to Wine. Example: "-debugmsg +all" will turn
all these messages on, "-debugmsg -dll" will turn all messages
concerning DLLs off.
* [controls/combo.c]
Added some handling for combo controls with ownerdraw-styles
(just creating and passing the necessary messages to the
corresponding listbox control; the edit-control needs to be
replaced with something else).
* [controls/edit.c]
[windows/dialog.c]
Added support for use of global heap memory in dialogs with
edit controls.

Exclude and Include no longer requires a terminating ';' to
register the last component.
Thu Sep 15 23:10:09 MET DST 1994 Dag Asheim (dash@ifi.uio.no)
* [Configure]
Rewrote much of it. Added capability to generate a wine.ini
file. Commented out the processor emulator options until that
becomes interesting. Gives a warning if it sees any *.rej
files. I hope I haven't assumed to much about the shell/OS so
that it breaks under *BSD.
* [misc/dos_fs.c]
Removed/changed calls to ToUnix() (which calls tolower()) so
that the part of the pathname which correspond with the drive
letter on DOS no longer will be mapped to lowercase. This
means that it should be possible to have uppercase letters in
the [drives] section of wine.ini.
* [LICENSE]
Cosmetic changes so that it displays better in the window you
get from pressing "Credit_License" in the "About WINE" window.
Sun Aug 21 21:12:06 MET DST 1994 <erik@xs4all.nl>
* [controls/menu.c]
LoadMenu() moved to loader/resource.c.

Removed duplicated code in *Resource() functions.
Moved NE-program specific functions into ne_image.c.
Moved NE-fileformat functions to ne_resource.c.

Added. Nothing implemented to run PE-executables, resource
loading only.
* [misc/file.c]
Changed OpenFile() to use macros.
* [misc/shell.c]
Added NULL-ptr checks to ShellAbout().
* [miscemu/int21.c]
Fixed a few typos.
* [miscemu/kernel.c]
Added _DI = _DS, to put the caller's instance in DI. Doesn't
work properly if caller changed DS :-(
