extracting window icons
by Brian Vincent June 10, 2005

June 10, 2005

Is there a way to extract an icon from a DLL? Wine seems to do this automatically when programs are installed, I just can't figure out how. Is there a way to do it from the commandline? -Brian

Wine 20050310 redraw problems (specifically with Paint Shop Pro 7)
by Jules Richardson June 10, 2005

June 10, 2005

I remember posting about this quite a while ago but decided to revisit it, and it seems like it's still an issue in the 20050310 build of wine. Wine has real trouble with refreshing drawing surface windows in Paint Shop Pro 7: - the background in a new image window isn't cleared - tools that display tooltips (such as the colour selector control) leave tooltip debris all over the drawing surface when they're moved around. - drawing surface isn't refreshed if partially / totally obscured by other windows and then made visible again. Normal windows, dialogs etc. are working fine (and tooltips work fine too above normal controls) - it would seem that the drawing surfaces in PSP7 are handled differently (presumably for speed reasons) and wine is having some serious problems handling them. Any ideas for a workaround / patch, or is this bug known about and in the pipeline to be sorted out? I've exhausted various options in the Wine config file to do with display output; the problem seems to be in core code somewhere. I get the following error message at startup as follows: fixme:ole:CoRegisterMessageFilter stub followed by several: err:region:CombineRgn Invalid rgn=(nil) ... the latter used to happen an awful lot in earlier wine builds whilst the app was being used, but note that it's *not* happening with the 20050310 build whilst I try and use the app; only at startup time. (In other words, it's quite possibly not related to the redraw issues at all) Any ideas? PSP7 is so "almost there" that it'd be a shame if it wasn't 100%... Happy to provide further details if someone gives me instructions as to what to look at! cheers Jules

Work being done at the File Creation Interface of Cabinet.DLL
by Gerold J. Wucherpfennig June 8, 2005

June 8, 2005

I just want to let you know that I'm working at the FCI functions of CABINET.DLL. I had a look at this a few years ago, but gave up soon. Two weeks ago I made a new attempt and next weekend I should be able I post a patch which implements all FCI functions and will work with spanning cabinets. Real file compression will not be implemented at that point of time as I still have to write missing parts and complete error handling first. This work took me longer than expected so let's see if I can adhere to my schedule. Regards, Gerold

Started to go through this and found something intresting. lwp.h does exist and is found, so HAVE_SYS_LWP_H is defined. The test for _lwp_create fails. Looking a bit deeper I found that the lwp.h for Solaris 9 is different from the one in Solaris 10 (which is what I am using). Based on this and something I read awhile ago, I belive that Sun is attempting to phase out the lwp stuff on Solaris. It looks like a workaround will need to be created for _lwp_create. I will look into this and see what is the "official" way to write the code now, if any. Also a workaround will need to be made for all other _lwp_* calls that no longer exist. Have Fun! Chuck Hall

Print unicode strings in tests
by Paul Vriens June 1, 2005

June 1, 2005

Hi, I'd like to print unicode-strings in some tests (for debugging purposes). The following however does not show nice output on wine (it does on windows): static const WCHAR dataW[] = {'S','o','m','e',' ','d','a','t','a',0}; UNICODE_STRING usdata = { sizeof(dataW)-sizeof(WCHAR), sizeof(dataW), (LPWSTR)dataW }; trace("Length is %d\n", usdata.Length); trace("Maximum Length is %d\n", usdata.MaximumLength); trace("The strings is %ls\n", usdata.Buffer); Our trace doesn't seem to be able to cope with %ls (or %S). Any ideas ? Cheers, Paul.

Re: Optionally map the unix filesystem instead of drive letters into the shell namespace

Please consider the configure based global flag only an option. That's actually what I said several times. It could be a per application option as well. And there is no problem in activating it via a wine-specific API, which would override the config on a per process basis. > Ok ... I know your approach is base everything on dos path and the > global flag is simply a display mode. > But what about the parsing of the file name editbox in the file dialog? > The user is browsing unix file system, but does the user enter unix or > dos path? > I believe I can modify your solution to accept unix file path, but it > have to accept dos path as well. Modifying shfldr_unixfs to parse unix path in addition to dos paths is trivial: Just remove the (pUnixFolder->m_dwPathMode == PATHMODE_UNIX) test in line 339. The real problem is the test for invalid chars in the filedialog, which '/' is one of. The solution is obvious: If wine is configured to display unix paths, then accept '/' as a valid char in paths in comdlg32. You will have to do this for your solution as well, don't you? > Then there is also the issue of having to have the unix root mapped to a > dos drive. That's true. Actually, we are tackling two slightly different problems here: I would like to have existend applications, for which I don't have the source, to display unix paths instead of dos paths in their file dialogs. So I want MS Office to display unix paths in it's file dialogs. IMHO there is not way to achieve this without the requirement to map one of the dos drives to '/'. At least not if the user should be able to access every file on his filesystem. This solution can also be applied to winelib applications. If you want to use the native posix file functions (which, frankly, I don't see a reason to do, because the user doesn't care how filenames look in the core dump, but only how they look on the screen) then just map the paths coming out of the file dialog to unix with the wine_nt_to_unix_path function. I do understand that there are some shortcomings of this approach for winelib applications, which can not possibly be addressed this way. But it seems equaly obvious to me that your approach can never achieve the goal I laid out above (To make native apps display the unix paths in file dialogs). So perhaps there might be demand for both solutions. Or perhaps I'm totaly off the point and the only person on the planet who likes to see unix paths in his native windows applications on wine. Which would mean your solution might be the only one people are interested in. What I meant to say is, please fell free to implement your solution the way you like it and let the wine community decide on it. But please don't modify shfldr_unixfs in a way that breaks my solution (Conceptually, that is. Bugs, of course, are unavoidable.) > Troy, Alexandre and I have been discussing other possible solutions to > this problem offline. I don't want to offend, but I think this just isn't fair. I have contributed a lot of my free time working on this stuff, and I think I would have deserved to be informed on discussions and decisions in this matter. Above that, this kind of discussion should take place on wine-devel, so that the community at large can take part in it. To me this gives the impression that you avoided discussing it on wine-devel, because you didn't want to be convinced. Sorry. Ok, nuff said, going back to the technological stuff. > One solution I have implemented and waiting on Alexandre's verdict is > the following. > > Create a new library called wineunixfs.

Borland C++ 4.5
by Andrew Neil Ramage June 1, 2005

June 1, 2005

When I tried to install BC++ 4.5, the installation proceeded normally. However, when I clicked "Finish", it trashed my X server, causing the system to stop responding to key presses and the mouse. I could not even kill the X server, and so had to pull the power cord out. Is this a known problem, and will I still be able to use my Development identity ? -- Andrew You can be the captain I will draw the chart Sailing into destiny Closer to the heart Closer to the Heart by Rush (A Farewell to Kings, 1977) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
