Mon Jun 19 20:29:50 1995 Alexandre Julliard (julliard@sunsite.unc.edu)
* [debugger/*.c]
Modified debugger to use segmented pointers everywhere.
* [if1632/shell.spec] [if1632/sound.spec] [if1632/user.spec]
Declared all functions that return only 16-bit as 'pascal16'.
* [include/ldt.h] [memory/ldt.c]
Export LDT_EntryToBytes (new) and LDT_BytesToEntry for DPMI.
Maintain a copy of the selector flags, removing the need to make a
system call to retrieve an LDT entry.
* [loader/module.c]
Fixed bug with module file handle cache.
* [loader/ne_resource.c]
Fixed file name bug in NE_AccessResource().
* [loader/resource.c]
Fixed bug in LoadIcon() that caused wrong colors to be used for
the icon mask.
* [loader/signal.c]
Moved instruction emulation to miscemu/instr.c.
* [misc/dos_fs.c] [miscemu/int21.c]
Lots of small fixes, thanks to Morten Welinder.
* [miscemu/dpmi.c]
More complete DPMI emulation.
* [miscemu/instr.c]
Added support for prefixes in instructions to emulate.
* [miscemu/int2f.c]
Use register macros instead of destroying the high part of 32-bit
registers.
* [objects/dc.c]
Fixed bug in GetDCState() that failed to clear the new DC.
* [rc/sysres.rc]
Removed dialogs 11 and 12 that were never used.
* [tools/build.c]
'pascal16' generated functions did not save %dx.
Removed use of %fs to access the stack.
%ds is no longer initialized before calling a 16-bit routine.
* [windows/defwnd.c]
Accept a NULL pointer as window title.
* [windows/mdi.c]
MDICascade: skip iconic windows.
Implemented CalcChildScroll().
* [windows/utility.c]
Fixed MulDiv() for illegal values.
* [windows/win.c]
Fixed X error in CreateWindowEx() when WM_NCCALCSIZE returned
a zero width or height.
Sun Jun 18 22:22:30 MET DST 1995 Fons Botman (botman@inter.nl.net)
* [controls/edit.c]
Fixed "uninitalized" message which -Wall couldnt see to be ok
in EDIT_WriteText.
* [include/debug.h]
Added define for extra checks in API definitions during debugging.
* [loader/ne_image.c]
Added newline in NE_FixupPrologs to avoid long lines.
* [misc/dos_fs.c]
Added extra safety check in DOS_ValidDrive.
* [misc/exec.c]
Fixed definition of ExitWindows.
Sun Jun 18 21:16:08 1995 Bernd Schmidt <crux@pool.informatik.rwth-aachen.de>
* [controls/edit.c]
Some fixes, mostly for memory management, but also for text selection
and tab postitions. General cleanup. Notepad.exe now works.
* [controls/combo.c]
Fix: the hwnd field of the DRAWITEMSTRUCT should always be that of
the combo box, not the ComboLBox that belongs to it.
* [controls/listbox.c]
Handle itemID field correctly throughout.
* [memory/local.c]
Implemented flag LMEM_ZEROINIT.
LocalReAlloc() could trash the heap. Fixed.
* [objects/font.c]
FONT_MatchFont(): don't get confused by negative widths.
Fixed a segfault in EnumFonts().
* [objects/text.c]
DrawText(): DT_CALCRECT implies DT_NOCLIP.
* [objects/dcvalues.c]
MAKELONG was used with bad parameters in DC_GET_X_Y.
* [windows/dialog.c]
Don't show the dialog if WS_VISIBLE isn't set in the template.
* [windows/utility.c]
UTILITY_convertArgs(): Never pass an expression containing ++ into a
macro...
* [windows/win.c]
SetParent() should unlink the window before changing the parent.
* [windows/message.c]
Don't call timer functions via CallWindowProc(), since it checks
whether hwnd==0 and does not call the function in that case.
* [miscemu/instr.c]
Ignore interrupt 0x3D, for VBRUN300.DLL.
* [misc/commdlg.c]
Don't rely on the itemData field of the DRAWITEMSTRUCT to contain a
pointer to the item text.
* [if1632/relay.c]
Disable OLE and DDEML DLLs by default, since they contain nothing but
stubs anyway. SHELL, COMMDLG and WIN87EM are left enabled, although
some programs may work better without them.
* [multimedia/*.c] [include/multimedia.h] [include/driver.h]
Begun cleaning things up a little. Replaced printfs with dprintf_
macros, made functions static where possible, and some other minor
changes.
Sun Jun 11 23:19:10 1995 Martin von Loewis <martin@informatik.hu-berlin.de>
* [debugger/dbg.y][debugger/dbg.l]
Removed special handling for FILE_IDENTIFER, because it caused
problems with x/<format> statements.
* [debugger/info.c]
Use SC_ESP instead of SC_EIP for stack dump.
* [misc/compobj.c][if1632/compobj.spec]
CoBuildVersion, CoInitialize, CoUninitialize: new functions
* [misc/ole2.c][if1632/ole2.spec][misc/Imakefile][include/ole2.h]
New files ole2.c, ole2.h
OleBuildVersion, OleInitialize, OleUninitialize: new functions
* [if1632/ole2disp.spec]
Added missing ordinals above 109
* [misc/ole2nls.c][if1632/ole2nls.spec][include/winnls.h]
New file winnls.h
GetLocaleInfoA: new function
* [if1632/shell.spec]
Added FindEnvironmentString as stub
* [misc/olecli.c][if1632/olecli.spec]
OleIsDcMeta: New function
* [objects/font][misc/gdi.spec]
GetKerningPairs: new function
* [misc/shell.c]
ShellExecute: Implemented support for starting programs
* [if1632/user.spec]
Inserted missing relay to GetClipCursor
Sun Jun 11 20:34:47 1995 Bernd Schmidt <crux@pool.informatik.rwth-aachen.de>
* [controls/edit.c]
Fix a problem with the local heap.
* [include/wintypes.h]
Fixed wrong declarations of CATCHBUF and LPCATCHBUF.
* [include/mdi.h] [windows/mdi.c]
This code still assumed segmented address==linear address. Fixed.
* [include/msdos.h] [misc/dos_fs.c]
The filemask field of the dosdirent structure could be overrun. Fixed.
If you had a file called foobar and a file called foo, trying to
FindFile(foo) could accidentally find file foobar instead. Fixed.
* [misc/file.c]
OpenFile(): Always return the full pathname in ofs->szPathName. This
also fixes GetModuleFilename().
Prevent _lclose() from closing stderr or stdout.
* [misc/profile.c]
Search for .ini files in the path of the current module as well.
(Needed by Lotus Organizer.)
* [loader/task.c] [loader/ne_image.c] [loader/module.c]
[memory/local.c]
Local heaps are now initialized by InitTask() for executables. DLLs
have to call LocalInit() themselves, LocalInit() has to put the
heap at the end of the segment when called with start==0. We no longer
allocate the DGROUP with 64k on startup, but grow the local heap
in LOCAL_GetBlock() when necessary.
* [loader/module.c]
LoadLibrary() should call LoadModule() in all cases, even if the
DLL is already loaded, to ensure that the reference count is correct.
* [loader/ne_image.c]
Some changes to function prolog fixup. Does anyone know exactly how
this is supposed to work? I am only guessing here.
In NE_InitializeDLLs(), initialize the DLLs a module refers to before
the module itself.
* [loader/task.c]
Initialize instance data at the beginning of the DGROUP in InitTask().
* [memory/local.c]
Some fixes for moveable blocks.
* [memory/selector.c]
All the IsBad*Pointer() functions returned exactly the wrong boolean
value in all cases!
* [objects/bitblt.c]
Fixed another null pointer dereference in debugging output.
* [objects/font.c]
Some more recovery possibilities for FONT_MatchFont() if a specified
font does not exist.
* [windows/win.c]
The dialog code may call CreateWindowEx with an integer in windowName.
This happens for static icon controls that expect a resource ID as
the window name. CreateWindowEx() used to crash. Fixed.
* [windows/class.c] [windows/win.c]
Window classes are owned by modules, not instances. Changed
RegisterClass(), UnregisterClass(), GetClassInfo() and CreateWindowEx()
accordingly.
Sat Jun 10 16:10:53 1995 Olaf Flebbe <o.flebbe@science-computing.uni-tuebingen.de>
* [miscemu/int21.c]
clock.exe was displaying incorrect year.
Fri Jun 9 20:36:56 1995 Victor Schneider <tailor@crl.com>
* [include/cursor.h] [windows/cursor.c]
Implemented CreateCursorIconIndirect().
