wine/controls/listbox.c
Alexandre Julliard 1e9ac79811 Release 960606 
Wed Jun  5 20:13:54 1996  Alexandre Julliard  <julliard@lrc.epfl.ch>

	* [controls/button.c] [controls/listbox.c]
	Fixed wParam of WM_DRAWITEM message.

	* [if1632/Makefile.in] [loader/builtin.c]
	Remove WPROCS32 DLL, as the relay code can call Wine routines
	directly.

	* [loader/module.c] [loader/ne_image.c]
	Fixed initial stack layout for self-loading modules.

	* [tools/build.c]
	Fixed data segment building for Win16 modules.

	* [windows/defdlg.c]
	Implemented Win32 versions of DefDlgProc().

	* [windows/dialog.c]
	Merged Win16 and Win32 dialog code.
	Added support for control extra data in dialog item template.

	* [windows/win.c]
	Unified Win16 and Win32 versions of CreateWindow().
	Implemented Win32 version of GetWindowLong().

	* [windows/winproc.c]
	Changed the implementation of window procedures, so that 16-bit
	winprocs are valid segmented pointers.

Sun Jun  2 16:39:46 1996  Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de>

	* [misc/registry.c]
	Fixed another bug in the w95 loader. Quietened some debug output.

Sun Jun  2 10:00:22 1996  Ulrich Schmid  <uschmid@mail.hh.provi.de>

	* [windows/winproc.c]
	Bug fix: WM_PARENTNOTIFY: don't fall through to WM_SETTEXT.

Sat Jun  1 12:37:22 1996  Tristan Tarrant <tst@sthinc.demon.co.uk>

	* [resources/TODO] [resources/sysres_It.rc]
	Updated font dialog box.

Thu May 30 21:05:19 1996  Albrecht Kleine  <kleine@ak.sax.de>

	* [include/commdlg.h] [misc/commdlg.c]
	ChooseFont() and ChooseColor(): 
	Bugfixes and added more support for some CF_* and CC_* flags: 
	dialog templates and font size control.
	Bugfix in structure definition of CHOOSECOLOR definition.

	* [ipc/dde_proc.c] [windows/event.c]
	Replaced SendMessage with SendMessage16 and added inclusion of
 	dde_proc.h for error-free compilation of ipc module.

Thu May 30 19:00:00 1996  Alex Korobka <alex@phm30.pharm.sunysb.edu>

	* [windows/scroll.c]
	Made ScrollDC to save/restore current clipping region.

	* [misc/clipboard.c] [windows/event.c]
	Implemented most of the previously missing features (not tested), 
	improved text pasting from/to X. 

	* [if1632/user.spec] [if1632/gdi.spec] [objects/dc.c]
	  [objects/gdiobj.c] [objects/clipping.c] [windows/dce.c]
	  [windows/winpos.c] [windows/painting.c]
	Updated DCE code, implemented dynamic invalidation of owned DCs.
	This fixes a lot of problems with scrolling in WinWord. Not
	sure about the effect on -desktop.

Wed May 29 23:35:44 1996  Jukka Iivonen <iivonen@cc.helsinki.fi>

	* [win32/time.c] [if1632/kernel32.spec]
	Added SetSystemTime and SetTimeZoneInformation.

	* [if1632/kernel32.spec]
	Added lstrcat, lstrcatA, lstrcmp, lstrcmpA, lstrcpy, lstrlen.

	* [include/windows.h]
	Added SYSTEM_POWER_STATUS structure and prototypes for
	GetSystemPowerStatus, SetSystemPowerState, SetSystemTime.

	* [include/kernel32.h]
	Added a prototype for SetTimeZoneInformation.

	* [win32/environment.c] [if1632/kernel32.spec]
	Added GetSystemPowerStatus and SetSystemPowerState stubs.
