Support for IDvdInfo2::GetDiscID
by James Courtier-Dutton March 25, 2005

March 25, 2005

The Windows api method uses the function call IDvdInfo2::GetDiscID http://msdn.microsoft.com/archive/default.asp?url=/archive/en-us/directx9_c… This returns a unique 64bit ID for a DVD. Has anyone found out what exactly it does to create this 64bit ID. It would be nice to get linux DVD players to be able to use the same method. Cheers James

text edit box not painting text ( on form startup )
by Doug Herbert March 9, 2005

March 9, 2005

( I have posted a similiar question in wine-users, don't flame me for doing so, just thinking about this some more, perhaps it may be more a developer question ) Ok, I have a windows app, that runs under wine fine - not quite. This app has a form, with many text field edit boxes on. Quite often these edit boxes already have text values, ie. they are not empty - there is a database behind the form. Anyway, the form shows on the screen, but the text within the edit fields is invisible, until you activate each edit box component. When you leave one edit box to the next, the text remains visible. It seems like the repainting is not working, on initial startup of the form. As a way to debug this database app ( I don't have the source code for it ) I wrote a real basic form app in Visual Studio, with two edit boxes, with data in each. Now this basic app shows the text values immediately on startup. So there must be something different that the database app is not doing. I then ran wine using 'wine --debugmsg +edit programname' for both app's. I see both logging 'Creating ANSI edit control, style = xxxxx' but the style reference is different between apps - I am not sure if this the cause or not. The problem app reports style = 54011104 and the basic app shows style = 50010080. Can somebody explain what this style reference means and how do I force an app to use a certain style of edit box ? What other wine class debugmsg types should I use to narrow down the source of this problem ? Is there anyway I can check to see how the database app is repainting text within the text edit components ? Regards Doug Herbert. __________________________________ Do you Yahoo!? Yahoo!

Re: Wine on FreeBSD current
by Gerald Pfeifer Oct. 30, 2004

Oct. 30, 2004

>> I'm just wondering if it is supposed to work as well as FreeBSD stable. Right now, Wine doesn't work at all on FreeBSD -STABLE: wine: failed to initialize: /swtest/wine/dlls/ntdll.dll.so: mmap of entire address space failed: Cannot allocate memory and before that I used to see deadlocks upon startup of non-trivial applications (such as Forte Agent, both 16bit and 32bit flavors). I believe there are also signficant threadings issues on -CURRENT, so overall Wine is hardly, if at all, usable on any version of FreeBSD I have access to, even though I'm still working to keep it at least compilable on FreeBSD 4.9 and 5.2/5.3.

Don't crash on failing DRIVER_FindFromHDrvr
by Uwe Bonnes Sept. 6, 2004

Sept. 6, 2004

Hallo, I sent a patch to prevent wine from crashing last friday. It happend, when DRIVER_FindFromHDrvr returned NULL. No I found out, that I had sent that patch before last year. Eric answered > this doesn't seem right to me: either the loading fails and we shouldn't > get a valid handle, or it succeeds and we should be able to find it > there's must be something wrong elsewhere > could you please send a -debugmsg +driver,+module,+winmm to see what > happens ? and like before, I can't reproduce the error after reverting the patch: > the error no longer exists. I guess some registry entry was corrupt and a > successfull run corrected it later. > > However I see a lot of check after DRIVER_FindFromHDrvr() in other parts of > the code... If one dose "grep -3 DRIVER_FindFromHDrvr wine/dlls/winmm/*", every other usage of DRIVER_FindFromHDrvr is like if ((lpDrv = DRIVER_FindFromHDrvr(hDrvr)) != NULL) Why should expecting a NULL return be wrong? It happens, as the the crashes show.

Wine bug with delphi Menus
by Robert van Herk Sept. 5, 2004

Sept. 5, 2004

Hi people, I think I discovered a wine bug. In a delphi program, changing the visibility of a menuitem (TMenuItem) causes the whole menu of that form to stop working, when the program is run under Wine. Behind the screens, the setVisible of a menu item calls MenuChanged. This seems to put the menu in such a state that, in wine, all menu components stop doing anything. I've written a small application (455 kb EXE) to show what goes wrong. Would anybody be interested to help me in solving this bug? Would a message trace from Winsight (for example) be of any help? Greetings, Robert

Remote operations -- need for advice
by Alexander Yaworsky Aug. 27, 2004

Aug. 27, 2004

I'm thinking how to implement CreateRemoteThread and besides fix memory management functions. The complete (afaik) list includes: RtlCreateUserThread NtAllocateVirtualMemory NtFreeVirtualMemory NtProtectVirtualMemory NtQueryVirtualMemory NtLockVirtualMemory (do nothing?) NtUnlockVirtualMemory (do nothing?) NtFlushVirtualMemory NtMapViewOfSection NtUnmapViewOfSection Suggested implementation. Let's add two groups of handlers to the wineserver, something like remote_operation_xxxx and remote_operation_xxxx_complete. remote_operation should do the following: 1) suspend_for_ptrace(); 2) inject a piece of code into required process and start its execution; 3) resume_after_ptrace(); 4) place calling thread into suspended state (or into some wait state?) remote_operation_complete should prepare reply and resume thread suspended by remote_operation. Injected code should call required function and then remote_operation_complete in context of required process. The question is: how to correctly get address of function? imho possible solutions are: 1) assume ntdll loaded at the same address for all processes -- unreliable; 2) get dll base address from per-process dll list and parse ELF by hand -- too complicated (?); 3) pass relative offsets and add them later to the ntdll's base address -- unreliable a bit: ntdll may be replaced, although, it is unlikely; 4) extend the struct process (server/process.h) and the request init_process with pointers to required functions -- most reliable and simple but looks ugly. What do you think?

I was worried that tracing all waveGetPosition() failures would clober the output but after that's what one wants when tracing is enabled.

I get the same results on Windows 95, 98 and NT4. How is it that this works on your machine? Anyway, assuming that we need to round up I propose to modify the implementation as in the attached patch. The advantage is that it does not rely on ceil(). In fact it doesn't even use floating point arithmetic so we cannot get any rounding error. If this patch is ok by you, then I can apply it to all the drivers. I also noticed that we have similar code for the input devices. Does this one also round up? Or does it round down?

console message encoding
by Vitaly Lipatov Aug. 15, 2004

Aug. 15, 2004

Is it known that console message printed to output in wine internal encoding (OEM?), not in locale encoding. Is it bug or just needed coding right behavior? For example, I have koi8-r as locale encoding, cp866 as OEM CP and cp1251 as ANSI CP. -- Lav Vitaly Lipatov Saint-Petersburg GNU! ALT Linux Team! LaTeX! LyX!
