However, how long are we going to support 'older' hardware? Most manufacturers give up after two years. James McKenzie

re: Forward SHLocalAlloc to kernel32 LocalAlloc

What app needs this? It's been discussed before a bit; Win 98 explorer used it, http://www.winehq.org/pipermail/wine-devel/2005-August/039487.html but http://www.geoffchappell.com/viewer.htm?doc=studies/windows/shell/shell32/a… says that ordinal 200 was later taken over by SHCreateDesktop. Unless we have a real good reason, we probably want to go with the later scheme. - Dan

Participate to GSoC
by Warren Dumortier 07 Feb '10

07 Feb '10

Hello everybody! First i'll present myself. So my name's Warren Dumortier and i live in Belgium, i've been using Wine for 4 years and i've always been interrested on how it works Also i'm quite active on AppDB for submitting apps. I actively program in C on Linux since 3 years as Gfire (our program) developer. As i actively program in C and would like to develop for WINE, i had a look at the GSoC wiki page. This year i could finally participate as i'm legally allowed now. Are there any specific things to know in order to be accepted as a GSoC student for WINE? These are the two ideas i'd like to implement: Theming - Implement Wine GTK/QT theming support Vista Game Explorer API - Implement the core functionality of this dll I don't know which one i would choose yet, but how are ideas assigned to students, are there requirements needed for each idea? Then i could for example get familiar with the idea before the GSoC starts... When can i ask to be GSoC student? Thanks in advance, kind regards.

[ mshtml missing function ]
by lementec fabien 06 Feb '10

06 Feb '10

Hi, I have mostly managed to make solidworks2010 work under the latest version of wine. The following function has a missing feature when called with the variant set to 3: dlls/mshtml.c::HTMLStyle_put_width I dont know anything related to mshtml, so it would be great if anyone is interested in implementing it... would make this great software works with wine. Regards, Fabien. -- the number of UNIX installations has grown to 10, with more expected. The unix programmer's manual, June, 1972

winedbg: output of the bt command misses sometimes a frame
by Bernhard Übelacker 06 Feb '10

06 Feb '10

Hello, as I was debugging in wine I wondered if following behaviour is intended or could be considered a bug (and should be filed in bugtracker?). When the debugger's current position is on the opening curly bracket of a function a "bt" command writes a different stack as if the current position is on the next instruction in this function. What me makes wonder is the frame 0 is always correct but the calling function is not in the stack at all in the first bt: Wine-dbg>bt Backtrace: =>0 0x7ebe3622 IsWindow(hwnd=0x20060) [/home/bernhard/data/entwicklung/2010/wine/wine-git/dlls/user32/win.c:2503] in user32 (0x0033b500) 1 0x7e25429d create_window16+0x5c(cs=0x33b53c, className="QWidget", instance=0x400000, unicode=1) [/home/bernhard/data/entwicklung/2010/wine/wine-git/dlls/user.exe16/message.c:2670] in user.exe16 (0x0033b520) 2 0x7ebe0f91 CreateWindowExW+0x7e(exStyle=1024, className="QWidget", windowName="pica", style=114032640, x=-2147483648, y=-2147483648, width=-2147483648, height=-2147483648, parent=(nil), menu=(nil), instance=0x400000, data=0x0(nil)) [/home/bernhard/data/entwicklung/2010/wine/wine-git/dlls/user32/win.c:1500] in user32 (0x0033b570) 3 0x650778f3 in qtgui4 (+0x778f3) (0x80000000) Wine-dbg>next 2507 if (!(ptr = WIN_GetPtr( hwnd ))) return FALSE; Wine-dbg>bt Backtrace: =>0 0x7ebe3637 IsWindow+0x15(hwnd=0x20060) [/home/bernhard/data/entwicklung/2010/wine/wine-git/dlls/user32/win.c:2507] in user32 (0x0033b2b0) 1 0x7ebe0bda WIN_CreateWindowEx+0x1201(cs=0x33b53c, className="QWidget", module=0x400000, unicode=1) [/home/bernhard/data/entwicklung/2010/wine/wine-git/dlls/user32/win.c:1406] in user32 (0x0033b500) 2 0x7e25429d create_window16+0x5c(cs=0x33b53c, className="QWidget", instance=0x400000, unicode=1) [/home/bernhard/data/entwicklung/2010/wine/wine-git/dlls/user.exe16/message.c:2670] in user.exe16 (0x0033b520) 3 0x7ebe0f91 CreateWindowExW+0x7e(exStyle=1024, className="QWidget", windowName="pica", style=114032640, x=-2147483648, y=-2147483648, width=-2147483648, height=-2147483648, parent=(nil), menu=(nil), instance=0x400000, data=0x0(nil)) [/home/bernhard/data/entwicklung/2010/wine/wine-git/dlls/user32/win.c:1500] in user32 (0x0033b570) 4 0x650778f3 in qtgui4 (+0x778f3) (0x80000000) Wine-dbg> Kind regards Bernhard

As a result just p will be stored as new data. Let's deal with previous patch first, next patch should most likely just duplicate it.

libpng dependency issue
by Luca Bennati 06 Feb '10

06 Feb '10

First: should i open a bug for this? The problem is from the new libpng 1.4.0: this evening i just updated this lib, and now i get compile error in dlls/windowscodecs/pngformat.c I'm still investigating the issue to find a solution, but the change that introduced this is clear, directly from their README: Removed deprecated functions png_read_init, png_write_init, png_info_init, png_permit_empty_plte, png_set_gray_1_2_4_to_8, and removed the deprecated macro PNG_MAX_UINT. So, what should WINE do? I see two actions that need to be performed: 1- check the libpng version in configure 2- adjust pngformat.c to work with the new lib. For a short term solution, needed also in the long term one (in the beginning), configure should give error if libpng isn't < 1.4.0 In the long term, while distros begin to ship libpng 1.4.0, the main developers of windowscodecs should work out a code solution. What is that i cannot say, since i don't really know the code, but i think it won't be a few minutes of work... This could apply also to libjpeg since it bumped to 8.0, but i didn't try that part yet.
