PATCH: DragQueryFileW (shellole.c; shell32)
by Sander van Leeuwen June 2, 2002

June 2, 2002

Hi, There appears to be a little bug in DragQueryFileW. According to MSDN pFiles is the offset in bytes. Did somebody make a mistake or was the LPWSTR cast added on purpose?

Shlwapi and user32 question
by Steven Edwards June 2, 2002

June 2, 2002

Hola, The only thing keeping me from building shlwapi is that its import the non-win32 call wvsnprintfA and wvsnprintfW from user32 to implement wvnsprintfA and wvnsprintfW. I did a search of the wine source tree and nothing else seems to depend on these functions being exported from user32. Can they be moved somewhere else or removed?

Possible minor bug in bin2res
by Steven Edwards June 2, 2002

June 2, 2002

Hola, I have been working on a small project that I am going to be submitting to the wine tree that used binary resources under windows and when I went to convert the files with bin2res I get this error "rename: File exists" It dumps the right wine resource information to the resouce-tmp file but when it goes to unlink the tmp file is when the error happens and the information must be manualy added to the rsrc.rc I traced it down, made sure that all other tmp file acces works in bin2res and and I think the problem is on line 245 if (rename(tmpfile, g_lpstrInputFile) == -1) { perror("rename"); unlink(tmpfile); return 0; } return 1; I have followed the directions on www.winehq.com for creation of a rsrc.rc to dump the resource information so I don't think I'm doing anything wrong. Can someone check this on windows to make sure I'm not just on the crack rock again? Thanks Steven "Every revolution was once a thought in one man's mind" - Ralph Waldo Emerson

User (developer ?) friendly execution trace
by max June 1, 2002

June 1, 2002

I find tracing a wine problem with wine --debugmsg for large programs unpractical. Usually you can know about exactly when a program hangs or behaves badly, but there's no way to activate/deactivate tracing after program start (afaik...) Being also a windoze (sigh) programmer, I find very useful some utilities like winspy that presents a window log in which you can start/stop tracing or logging of wine messages, system calls and so on, and activate/deactivate filters on the fly. This would allow spotting the bug when it arises instead of having tenths or hundreds of mbyte of logs. I could implement it as a filter taking input from wine, but I guess it'll slow downn much apps, having to parse wine output on the fly. Much better would be an internal implementation.... Some comments about ? Regards Max

DOS memory Question..... or How to increase base memory for DOS apps
by Christian Costa June 1, 2002

June 1, 2002

Hi, Many DOS apps needs a lot of base memory even if EMS or XMS memory are used. The first 64K of memory being lock to catch null pointer, the DOS memory must start at 0x10000 as you can see in the code below (msdos/dosmem.c) : /*********************************************************************** * DOSMEM_InfoBlock * * Gets the DOS memory info block. */ static dosmem_info *DOSMEM_InfoBlock(void) { return (dosmem_info*)(DOSMEM_dosmem+0x10000); /* 64K */ } /*********************************************************************** * DOSMEM_InitMemory * * Initialises the DOS memory structures. */ static void DOSMEM_InitMemory(void) { /* Low 64Kb are reserved for DOS/BIOS so the useable area starts at * 1000:0000 and ends at 9FFF:FFEF. */ Changing this value to the end of the BIOS DATA area (0x500) does the job and things work as expected (at least for DOS apps). But I was told that this causes problems for others apps. Probably for Win16 ones that use DOS3CALL and not int21h via DPMI. If it's true, a solution could be to initialize DOS memory differently for pure DOS apps by modifying the DOSMEM_Init function. DOSMEM_Init is called at 3 different places : - process_attach in dlls/kernel/kernel_main.c - DOSVM_Init in dlls/winedos/dosvm.c - MZ_InitMemory in dlls/winedos.dosvm.c and acts differently the first and second calls. Since I don't know wine internals enough and the "flow of execution", I have no idea how to do it in a clean way that do not break everything. If someone can help me or give me hints? A+ Christian

How to fix SizeOfImage when loading a builtin dll ?
by Laurent Pinchart June 1, 2002

June 1, 2002

Hi everybody, I noticed that, when a builtin dll (.so) is loaded, the SizeOfImage field in the OptionalHeader is not updated and stays equal to page_size (see winebuild, spec32). I need to get the correct value in SizeOfImage. I thought about updating that field in map_dll(a)library/loader.c, but don't know how to get the size of the image. Could anyone help me ? I'm not familiar with the PE loader. Thanks in advance, Laurent Pinchart

translating docs
by Damian Wojslaw May 31, 2002

May 31, 2002

Hello I just posted similiar thing on wine-users, but Anriy Palamarchuk said, that he intend to say something about it here. I thought I might as well give him a good opportunity and ask: what about translating docs? Those at WineHQ and within Wine tree? What I would like to know is, which of them would you like to see translated first (as for now, I am, unfortunately, the only person I know of, that intends to do this)? What about user interface? How do you want to distribute it - want to have it at your site, or ony host a link? And so on, and so forth, and whatever... :)))) -- Damian Wojslaw

Hi all, could you have a look at bug #751 and check the values on your Windows version and add a comment to the bug on what your version does ? (please don't forget to only check for partitions > 2GB !!) Thanks !

Re: PATCH: libntddl.so not found

I think this should be in the top-level Makefile to avoid having it scroll off the screen. Also it would be nice to check LD_LIBRARY_PATH to avoid needlessly scaring users who have a working config already. -- Alexandre Julliard julliard(a)winehq.com
