Good source of test case source?
by Dan Kegel Feb. 9, 2003

Feb. 9, 2003

Source code downloaded from any *.microsoft.com server is copyright Microsoft, and they would not take kindly to us using it in our regression test suite, I'm sure. I hope I speak for everyone here when I say it seems important to carefully obey the letter of the law when it comes to avoiding copyright issues that might taint our efforts. So where should a developer go to find good code snippets when writing Wine regression or compliance tests, without running afoul of copyright laws? One possibility is http://www.codeproject.com. Their submission page, http://www.codeproject.com/info/submit.asp, quite clearly states: "If you post to CodeProject then you retain copyright of your article and code. You also give CodeProject permission to use it in a fair manner and also permit all developers to freely use the code in their own applications. ... You are more than welcome to submit code that is already published at another site, provided you own the copyright on that article, and provided you have not given the other site exclusive rights to your article." That sounds like code at CodeProject is fair game. Do other (smarter) people agree? I ask, of course, because I'd like to make sure it'll be ok to submit a testcase based partly on CodeProject code.

Error installing iKernel.exe: (0x1400)
by Dan Kegel Feb. 9, 2003

Feb. 9, 2003

This is something I see frequently. Here's my little FAQ about it: When running an Installshield 6 installer: If you get the error "Error installing iKernel.exe: (0x1400)" at any point, it's probably because there are leftover processes from a previous try. You can verify this with the command $ ps augxw | grep wine If that command shows old copies of wine running your setup, you need to kill them before you can run the setup program. If there are no other Wine programs running, you can kill them all with the command $ killall wine If you're also running Wine programs you care about, you'll have to kill off the old Setup instances one by one using kill and the individual PIDs (or perhaps Wine's spiffy Task Manager, which doesn't exist yet). Then repeat the ps to make sure the old wines are gone. - Dan -- Dan Kegel http://www.kegel.com http://counter.li.org/cgi-bin/runscript/display-person.cgi?user=78045

Iirc there was a vesion of FreeType that incorrectly swapped the meaning of matrix.xy and matrix.yx, but as I understand it this has now been corrected. Which version of FreeType have you been using? We could probably add a run time check to work around this bug if need be. Huw.

Re: Map "MS Sans Serif" font -> "Microsoft Sans Serif"

Under HKLM\\Software\\Microsoft\\Windows NT\\CurrentVersion\\FontSubstitutes something of the form "MS Sans Serif"="Microsoft Sans Serif" should work. Huw.

Hi, The problem with this code is that it won't work for rotated text. Also the line widths and positions should be obtained using from the OUTLINETEXTMETRICS structure. Huw.

Re: Fix module entry deallocation in MODULE_DecRefCount
by Warren_Baird＠cimmetry.com Feb. 8, 2003

Feb. 8, 2003

>the fix doesn't seem the right one... could you post a -debugmsg >+file,+module of what really happens here The places I've seen it happen are in parts of a large and complicated program - I'll see if I can find a simple test case that repros the problem and post a trace here. But I can give you more details on what I found happening... After calling LoadLibrary("foo") there were two entries for library foo in the MODULE_modref_list. When you unloaded the library the first entry found was removed, but the 2nd entry remained, but the memory behind it didn't exist any more. If you tried to load the library again, the loading code would find the entry in the modref list and try to reuse it, and immediately segfault... I seem to recall that the first entry had the correct path to the library, and the send entry had "C:\windows\system\foo.dll" or something like that... Note that I've only observed this on a sparc/solaris system - it may be due to a pecularity of the way libs are loaded there... If I can repro it with a simple enough case to generate a reasonably sized log, I'll post it here, hopefully tomorrow... Warren

OLE speed, builtin vs. native
by Dan Kegel Feb. 8, 2003

Feb. 8, 2003

I'm testing an Installshield 6 setup program tonight against wine-20030115 remotely over a 1Mbit/sec link. Running native $ wine SETUP.EXE takes 1 minute 40 seconds to put up the main dialog. With the DLL overrides $ wine --dll compobj,storage,ole,ole2,ole32,oleaut32,rpcrt4=n SETUP.EXE it takes 1 minute 10 seconds. So our OLE seems to be noticably slower. I imagine we'll fix that up before 1.0. - Dan -- Dan Kegel http://www.kegel.com http://counter.li.org/cgi-bin/runscript/display-person.cgi?user=78045

Various Visual FoxPro bug reports filed
by Paul McNett Feb. 7, 2003

Feb. 7, 2003

Hello, I just filed 5 bug reports (1263-1267) regarding various issues with Microsoft Visual FoxPro. These represent some of the most obvious issues, but I'm sure I'll find more as I move my Visual FoxPro development over to Linux from Windows. I have a demo Visual FoxPro application that demonstrates these issues and a few more that I haven't reported in BugZilla yet. You can get this app from my site at: http://www.paulmcnett.com/vfp/testwine/ I'll be updating this app as new issues are discovered and old ones resolved. I'll now take this opportunity to thank everyone here for making Wine what it is today: you are giving me the ability to move off of Windows completely and yet still use my favorite development environment. Kudos to everyone involved! -- Paul McNett - p(a)ulmcnett.com Hollister, California, USA

145 Gnu Makefiles for all Petzold Programs
by John Kopplin Feb. 7, 2003

Feb. 7, 2003

I have just completed 145 Gnu makefiles that allow the free MinGW (Gnu) Compiler to compile and execute all of the example programs which Charles Petzold describes in his "Programming Windows Fifth Edition" book, which is the standard reference book on Microsoft's WIN32 API. I freely distribute these 145 makefiles in a .ZIP file, along with an installation program that will copy them into Petzold's directory structure, from my web page at: http://www.computersciencelab.com/Petzold.htm Only 5 of the 145 programs require user intervention to compile with the Gnu compiler, which is not bad for porting that many programs to a new compiler, especially given Microsoft's lax adherence to standards. I would be very pleased if these makefiles would help with the development of the Wine emulator. John Kopplin _________________________________________________________________ Tired of spam?

To select or LBS_NOSEL...
by Ferenc Wagner Feb. 7, 2003

Feb. 7, 2003

Hello, can anybody think of a way that a listbox with LBS_NOSEL style can still highlight a row, return meaningful values for LB_GETCURSEL and in general behave exatly like a selectable one? This is the behaviour I see under Win 95 and XP (using Spy++), and what I can achieve under Wine by unsetting the LBS_NOSEL attribute in LISTBOX_Create. What's going on? MSDN tells what you'd expect... I would be grateful for any insight. I hope to create some test program soon, but since I've never coded Windows GUIs it will probably take some time and brain cells. Feri.
