Sun Mar 24 13:13:11 1996 Alexandre Julliard <julliard@lrc.epfl.ch> * [include/win.h] [windows/*.c] Replaced next, parent, child and owner handles by pointers in WND structure. This should improve performance, and should be reasonably safe since Microsoft did the same in Win95. * [include/wintypes.h] [*/*] Redefined HANDLE to be UINT instead of a pointer for Winelib. This allows removing a lot of unnecessary casts and NPFMTs. * [windows/caret.c] Create the caret brush upon CreateCaret(); use the bitmap dimensions for the caret. Fixed CARET_DisplayCaret() to use PatBlt(). Fri Mar 22 16:00:00 1996 Anand Kumria <akumria@ozemail.com.au> * [misc/winsocket.c] More sanity checks, fixup some erroneous return codes. * [documentation/winsock] Description of how compatible the winsock is currently. Fri Mar 22 13:05:34 1996 Ulrich Schmid <uschmid@mail.hh.provi.de> * [library/winmain.c] Set `lpszCmdParam' by concatenating arguments. * [loader/module.c] WinExec: accept Unix commands, use Wine emulator. Mon Mar 18 12:16:27 1996 Martin von Loewis <loewis@informatik.hu-berlin.de> * [if1632/kernel32.spec][win32/thread.c][include/kernel32.h] DeleteCriticalSection, EnterCriticalSection, InitializeCriticalSection, LeaveCriticalSection, TlsAlloc, TlsFree, TlsGetValue, TlsSetValue: new functions. CRITICAL_SECTION: new structure. * [if1632/kernel32.spec][win32/code_page.c] WideCharToMultiByte: new function. * [if1632/kernel32.spec][win32/file.c] GetFileAttributesA: new function. * [if1632/kernel32.spec][misc/main.c] GetEnvironmentStringsW, FreeEnvironmentStringsA, FreeEnvironmentStringsW: new functions. * [if1632/user.spec][win32/cursoricon32.c][win32/Makefile.in] cursoricon32.c: new file. LoadCursorA, LoadCursorW: modified implementation from LoadCursor to WIN32_*. LoadIconA, LoadIconW: modified implementation from LoadIconA32 to WIN32_*. * [include/struct32.h] pragma pack inserted. CURSORICON32 structures added. * [include/winnls.h] Constants CP_* and WC_* added. * [loader/pe_image.c] PE_LoadModule: call PE_InitDLL with hModule rather than wpnt. Sun Mar 17 16:59:12 1996 Albrecht Kleine <kleine@ak.sax.de> * [misc/commdlg.c] Introduced hook function handling in file dialog. Removed an unnecessary ShowWindow call in FILEDLG_WMCommand(). Thu Mar 14 10:50:00 1996 Thomas Sandford <t.d.g.sandford@prds-grn.demon.co.uk> * [if1632/gdi32.spec] Added GetNearestColor. * [if1632/kernel32.spec] Added GlobalAddAtomA. * [win32/param32.c] Added stackframe.h to includes. WIN32_GlobalAddAtomA() - new function.
