edit control bug - EM_LIMITTEXT does not work
by Felipe W Damasio 14 Feb '03

14 Feb '03

Hi, When you try to limit the maximum chars accepted in an edit control by doing something like this: SendMessage(hwndEdit, EM_LIMITTEXT, 10, 0); Wine simply ignores it, and let the user type more than 10 (in this example) characters. This looks bad, because the user could eventually overflow the allocated memory for the dialog, making the program crash. Cesar Mello (mello(a)elipse.com.br) coded a little program to show this limitation: ftp://ftp.elipse.com.br/pub/about1/about1-src.tar.gz I just created a bug entry on bugs.winehq: http://bugs.winehq.com/show_bug.cgi?id=1280 Could someone help me with this? Thanks a lot and kind regards, Felipe

I regularly compile some of the DLLs under MSVC. The current state of DLLs is so that the non core DLLs compile usually almost fine but linking is a quite big issue I haven't fully tackled. If I link with the MSCV libs I get often undefined imports and linking with MSVC generated import libs from Wine source requires some hand work, as the MSVC IDE only generates the import lib AFTER the entire DLL has been successfully created, so you get sort of a catch 22 situation. Another issue is that most of the DLLs are not yet in a state where they can possibly be put into a current Windows installation, without causing all sorts of crashes and weird problems. The interdependencies between DLLs in a W2K installation is really enormous and a lot of functions in the Wine DLLs are not yet implemented or not fully complient. Rolf Kalbermatter

DirectSound problems
by Matthieu Foillard 14 Feb '03

14 Feb '03

It seems that there is a bug with DirectSound. Using Half-life, when i start the console, it goes into un infinite loop : $ /usr/bin/wine --debugmsg +dsound Program\ Files/Half-Life/hl.exe -- -opengl -game cstrike -windowed -console -noipx 2> /tmp/log it says : ... warn:dsound:DSOUND_MixCancelAt (0x403f6318, 0), buf_mixpos=25296 trace:dsound:IDirectSoundBufferImpl_Unlock (0x403f6318,0x403f6410,65536,(nil),0):stub trace:dsound:IDirectSoundBufferImpl_Lock (0x403f6318,0,65536,0x40760064,0x40760054,0x4076005c,0x40760058,0x00000000) at 60129 trace:dsound:IDirectSoundBufferImpl_Lock ->65536.0 trace:dsound:IDirectSoundBufferImpl_Lock locking prebuffered region, ouch warn:dsound:DSOUND_MixCancelAt (0x403f6318, 0), buf_mixpos=25296 trace:dsound:IDirectSoundBufferImpl_Unlock (0x403f6318,0x403f6410,65536,(nil),0):stub trace:dsound:IDirectSoundBufferImpl_Lock (0x403f6318,0,65536,0x40760064,0x40760054,0x4076005c,0x40760058,0x00000000) at 60129 trace:dsound:IDirectSoundBufferImpl_Lock ->65536.0 trace:dsound:IDirectSoundBufferImpl_Lock locking prebuffered region, ouch ... Over and over and the game console is "lock". If I disable sound (by comment out oss driver in ~/.wine/config) it works fine. I have this problem using both oss and arts driver. Sometimes after some times, it works and the game console unlocks and all goes fine. Sometimes i wait for a long time and it never works. i have an es1370 sound card, kernel 2.4.20, /dev/dsp0 and /dev/dsp1 are both working. It seems that the game menu use /dev/dsp1 and the game itself (e.g. the console) uses /dev/dsp0. I can't explain this.

named pipes still broken?
by Dan Kegel 14 Feb '03

14 Feb '03

Is it just me, or are named pipes broken for other people, too? In my tests, Wine can create named pipes, but the reading side can't open them. (Even without my recent changes to sync.c which added filename checking.) - Dan -- Dan Kegel http://www.kegel.com http://counter.li.org/cgi-bin/runscript/display-person.cgi?user=78045

Since the parameter of interest is specifically named "fsname" rather than "fstype" or "Filesystem", perhaps that should be the configurable parameter name. I would think that would eliminate any confusion.

For your consideration, here's a preview of some new seh_try_macros-type stuff...
by Gregory M. Turner 14 Feb '03

14 Feb '03

Let me know what you think of these. So far, I like them better than the original versions, although in solving some limitations of the old macros, I've created some new ones. This version avoids ({ }) entirely, in favor of Ove's original thought, which was to use __LINE__; therefore, putting multiple __(finally|except) clauses in the same line probably breaks. Otherwise, these are better macros. They are slightly more easily understood (although still pretty darn confusing, especially in the debugger), probably more resiliant against compiler optimizations, and have much less awful performance. Best of all, they ought to properly re-raise exceptions after executing finally clauses. There is some cruft in there, btw, which will be fixed before I submit anything to patches. They still break break/continue, of course, since they still rely on __TRY / __EXCEPT blocks to do the dirty-work. You can run the original seh_macros.c test against these successfully, except for the "absurdly nested" ones which use macros and presumably would fail quite dramatically due to __LINE__ duplications. FWIW, compared to the degree of "pressing need" for these macros, I have already spent way too much time on them... But the old ones kind of sucked, and, frankly, it's a fun semantic puzzle that requires pusing the limits of good old cpp just a _bit_ further than may have been intended ... so, here it is. Note that I'm declaring a variable in the header file here. I guess, I should fix this by creating an internal API in ntdll? I never quite figured out whether global non-static variables in a dll are thread-local, or what... (same for lexically scoped static ones -- real clueless here, and building a new system so I don't have much doco's at my fingertips ATM) Sooo.... Anyone want to help me decide what's the best way to get a thread-local global variable instantiated? Probably, my previous attempt with TlsAlloc was semantically correct, but that was /way/ too fat a solution, I'd like something much quicker if its at all possible. Otherwise this won't be threadsafe, which seems like a bad call, esp. since such code will probably end up being used to guard against unacceptable resource leakage.. warning, cut-and-pasted this patch in chunks so it might be bugged... should be clear enough how to duplicate, however, if it fails... --- ../wine.vanilla/include/wine/exception.h 2003-01-29 21:50:14.000000000 -0600 +++ ./include/wine/exception.h 2003-02-09 01:33:45.000000000 -0600 @@ -21,8 +21,12 @@ #ifndef __WINE_WINE_EXCEPTION_H #define __WINE_WINE_EXCEPTION_H +/* WRC can't find setjmp.h.

wcmd autoexec.bat?
by J. Grant 14 Feb '03

14 Feb '03

Hello I have been testing wcmd to automate some process I used to use on win98. However I can not find the autoexec.bat for wcmd? Currently the wcmd shell starts up with no prompt, this has to be corrected in my batch files. prompt $p$g etc. Wine seems to have 2 autoexec.bat's but does not seem to ever use them. /var/lib/wine/autoexec.bat never seems to be executed. Neither is the one I created in my fake c drive (/home/now3d/.wine/c/autoexec.bat) Is this issue known? are their any workarounds? Regards JG

Keyboard shortcut to disable DXGrab?

What would be involved in implementing a keyboard shortcut (ideally configurable) to temporarily disable DXGrab, when playing a game in a window?
