![Alexandre Julliard](/assets/img/avatar_default.png)
Tue Sep 28 19:59:21 1993 David Metcalfe * [windows/win.c] Implemented support for windows with no borders. Added GetParent(), GetDlgCtrlID(), GetWindowText() and GetWindowTextLength() functions. * [misc/xt.c] Added processing of WM_GETTEXT and WM_GETTEXTLENGTH messages to DefWindowProc and Implemented MessageBeep(). * [windows/syscolor.c] Added preliminary system color support. * [controls/button1.c] Mods to new button control and integration with Wine. Tue Sep 28 19:59:21 1993 Johannes Ruscheinski * [controls/button1.c] New button control using GDI functions. Tue Sep 28 19:59:21 1993 Eric Youngdale * [debugger/*] Added debugging capabilities to Wine Sat Sep 25 13:22:50 1993 Alexandre Julliard (julliard@di.epfl.ch) * [objects/region.c] Bug fix Fri Sep 24 07:35:11 1993 Bob Amstadt (bob at pooh) * [tools/build.c] Changed the entry point code to reduce the standard entry point size from 22 bytes to 10 bytes. This leaves about 4000 free entry points instead of the 800 in version 0.4.2. * [loader/resource.c] Rewrote functions to allow loading of resources from any DLL. * [loader/wine.c] [include/wine.h] Added functions GetFilenameFromInstance() and GetFileInfo() to search for a loaded file based on its instance handle. Added a field in struct w_files to make searching by an instance handle faster. Tue Sep 21 09:57:01 1993 miguel@roxanne.nuclecu.unam.mx (Miguel de Icaza) * [misc/profile.c] Implementation of .INI file handling Mon Sep 20 10:54:32 1993 David Metcalfe * [misc/profile.c.old] Implementation of .INI file handling Mon Sep 20 10:54:32 1993 John Brezak * [controls/WinButton.c] Bug fix with call to XtVaSetValues. Mon Sep 20 10:54:32 1993 Alexandre Julliard * [windows/win.c] Quick patch to get colormaps to work with button widget. Mon Sep 20 02:42:54 1993 (yngvi@hafro.is) * misc/keyboard.c: Ifdefed out some bogus Ansi<->Oem conversion functions * misc/lstr.c: New file with string functions like lstr* IsChar* *Ansi* Wed Sep 15 20:35:10 1993 John Brezak * [loader/signal.c] Additional changes to support NetBSD. Wed Sep 15 22:19:22 1993 Martin Ayotte * [windows/graphics.c] Added FrameRect function Tue Sep 14 13:54:45 1993 Alexandre Julliard * [objects/color.c] [objects/palette.c] Preliminary support for private color map. * [windows/class.c] Implemented CS_CLASSDC style. * [windows/dce.c] Moved DCEs to USER heap. Implemented class and window DCs. * [windows/event.c] Implemented CS_DBLCLKS style. * [windows/graphics.c] Bug fix in SetPixel(). * [windows/win.c] Implemented CS_OWNDC style. Implemented Get/SetWindowLong(). * [controls/menu.c] [windows/class.c] [windows/clipping.c] [windows/dce.c] [windows/message.c] [windows/win.c] Moved windows from global heap to USER heap.
