Alexandre Julliard 3f2abfaa0a Release 940815
Tue Aug  9 23:58:29 MET DST 1994	<erik@hacktic.nl>

	* [misc/file.c]
	OpenFile(): Completly rewritten.

	* [miscemu/int21.c]
	CreateFile(): Fixed wrong mode in call to open.
	OpenExistingFile(): Implemented file sharing.
	FindNext(): Fixed.
	CreateNewFile(): Fixed wrong mode in call to open.
	fLock(): Added to handle record locking.
	GetFileAttribute(): Added.
	As a result, AH = 0x5c, 0x09, and 0x0b were changed.

	* [miscemu/int2f.c]
	AH = 0x10: SHARE installation check
 
	* [loader/resource.c]
	AccessResource(): Fixed. A new file descriptor will be returned by
	every call to AccessResource().

	* [windows/utility.c]
	wvsprintf(): Fixed.

	* [controls/menu.c]
	FindMenuItem(): Fixed (handling for nPos == -1 added).	

	* [windows/win.c]
	CreateWindowEx(): Added call to WINPOS_GetMinMaxInfo.

	* [Configure]
	Added two options for a processor emulator that might be
	plugged in later..

	* [loader/task.c] [include/toolhelp.h] [if1632/toolhelp.spec]
	CreateNewTask() stores real modulename instead of 'TASKxxxx'.
	Added TaskFirst(), TaskNext(), TaskFindHandle().

	* [memory/global.c]
	Added stub for MemManInfo().

	* [objects/text.c]
	Added stub for GetTabbedTextExt().

	* [miscemu/*]
	Changed all references to registers. Please don't access
 	the context structure.
	fix for GetSystemTime() by <jspeter@birch.ee.vt.edu> added.

	* [misc/lstr.c]
	Fixed bug in AnsiUpper() & AnsiLower().

	* [misc/winsocket.c]
	bugfix in getsockopt()/setsockopt(): winsock uses different values
	than unix.

	* [objects/dib.c]
	Added DIB_SetImageBits_RLE[48] to support compressed bitmaps.

Mon Aug  8 21:12:33 1994  David Metcalfe <david@prism.demon.co.uk>

	* [controls/edit.c]
	Added support for WM_COPY, WM_CUT and WM_PASTE messages.

	* [windows/dialog.c] [windows/defdlg.c] [include/dialog.h]
	Modified dialog code to create new heap for edit controls
	unless DS_LOCALEDIT style is set.

Thu Aug  4 18:50:56 1994  Alexandre Julliard  (julliard@lamisun.epfl.ch)

	* [controls/button.c] [controls/edit.c] [controls/static.c]
	Removed unneeded GlobalUnlock() calls.

	* [controls/menu.c] [include/menu.h]
	Lots of changes, fixed a lot of old bugs and introduced a lot of
	new ones :-)
	- Changed message loop to use MSG_GetInternalMessage().
	- Fixed a bug that caused the main window to lose activation when
	  displaying a menu.
	- Correctly send initialisation messages (WM_INITMENUPOPUP).
	- Implemented EndMenu() and LookupMenuHandle().
	- Changed internal structures to be as compatible as possible with
	  MS-Windows.
	- Allocated everything on the USER heap instead of the global heap.
	- Prefixed all internal function names with MENU_ and declared
	  them static.
	- Moved "About Wine..." handling to NC_HandleSysCommand().
	- Multi-line menus should now work correctly.

	* [loader/resource.c] [objects/bitmap.c]
	Added the possibility to create OEM bitmaps directly as X bitmaps.

	* [objects/dcvalues.c] [windows/dc.c]
	Fixed GetDCOrg() to return screen coordinates.

	* [windows/message.c]
	Fixed double-click checks when the message is not removed from the
	queue.
	Fixed MSG_GetInternalMessage() to send WM_ENTERIDLE messages.

	* [windows/nonclient.c]
	Bug fix in system menu hit-test calculation.
	A few changes for new menu functions.

        es->textlen was being used before being set

        * [controls/menu.c]
        Bug fix in MENU_DrawMenuItem
