Sun Apr 14 12:51:27 1996 Alexandre Julliard <julliard@lrc.epfl.ch> * [controls/menu.c] [include/dialog.h] [windows/dialog.c] Made the resource loading code always use the correct Windows layout for Winelib on other CPUs. * [include/module.h] [loader/module.c] Added self handle in NE_MODULE structure, so we can use a pointer instead of a handle. Added function MODULE_GetPtr() to validate a HMODULE. * [memory/heap.c] Implemented Win32 heap management. * [memory/selector.c] Fix selector limit for huge blocks. Sat Apr 13 00:19:12 1996 Huw D. M. Davies <h.davies1@physics.oxford.ac.uk> * [objects/metafile.c] Fixed memcpy bug to allow memory based metafiles to work. Fri Apr 12 19:25:41 1996 Frans van Dorsselaer <dorssel@rulhm1.leidenuniv.nl> * [controls/edit.c] [controls/EDIT.TODO] Complete rewrite. Everything changed: new features, new bugs. Main addition: WordWrap. Fri Apr 12 20:29:55 1996 Tristan Tarrant <tst@dcs.ed.ac.uk> * [resources/sysres_It.rc] Fixed a few mistakes in the file and resized some of the controls. Fri Apr 12 09:55:13 1996 John Harvey <john@division.co.uk> * [misc/winsocket.c] Fixed broken #if defined that stopped unixware compiling. * [win32/resource.c] Added missing return to end of FindResource32. Thu Apr 11 18:00:00 1996 Alex Korobka <alex@phm30.pharm.sunysb.edu> * [windows/keyboard.c] [windows/event.c] Fixed GetKeyState for mouse buttons. * [windows/message.c] WM_MOUSEACTIVATE wasn't sent in some cases. Wed Apr 10 18:59:53 1996 Niels de Carpentier <niels@cindy.et.tudelft.nl> * [objects/font.c] Match slightly bigger font if height negative. Mon Apr 8 13:46:15 1996 Deano Calver <deano@rattie.demon.co.uk> * [multimedia/mmsystem.c] Changed read's to FILE_read's in mmsystem to fix mmio bug. Sun Apr 7 21:40:29 1996 Albrecht Kleine <kleine@ak.sax.de> * [misc/commdlg.c] [resources/sysres_En.rc] [resources/sysres_De.rc] Introduced ColorDlgProc() for ChooseColor() and replaced fitting En-,De- resources. As written in TODO: some national language support is needed here.
