WIN_FindWndPtr

Hey just out of curiosity, now that we are working toward v1.0 (not like we werent before) shouldnt this error be changed over to a fixme? It doesnt seem like all that much needs to be done (aside from marshalling and whatnot). Just wondering if we were planning on fixing it before v1.0, as it would be a big boon to have it still there in v1.0... -Dustin

bug (regression) in ddraw/d3d
by J. Hoffmann 03 Dec '02

03 Dec '02

Hi, I wanted to play around with the improvements to ddraw/d3d, and tried to run Final Fantasy 8 which worked before in software rendering mode with the native direct music dlls. Unfortunately FF8Config (and FF8 itself) crashes now with the recent changes. The patch which introduces the regression is: http://www.winehq.com/hypermail/wine-cvs/2002/11/0231.html (cvs version just before the patch works, applying the patch results in a pagefault.) The problem appears to be that GL_IDirect3DImpl_3_CreateDevice gets called with an rclsid = IID_D3DDEVICE2_OpenGL instead of IID_D3DDEVICE3_OpenGL, so that an D3DDevice2 gets created for the Direct3D3 interface (which results in a pagefault later, when the device is used.) See traces below. Im still trying to find the bug (and then a fix :-), but it would help me a lot, if someone could tell me where the GL_IDirect3DImpl_3_CreateDevice gets called from. (I see that it is an entry in the vtable but haven't found the function there it gets gets called yet..) regards, Jens Hoffmann ** trace for the old version: (cvs 11/24/02 16:14:09 CST) ** ... trace:ddraw:Main_DirectDraw_QueryInterface (0x403a4568)->({bb223240-e72b-11d0-a9b4-00aa00c0993e},0x40852 3cc) trace:ddraw:direct3d_create creating implementation at 0x403a5380. trace:ddraw:Main_DirectDraw_QueryInterface returning Direct3D3 interface at 0x403a5384. trace:ddraw:Main_DirectDraw_AddRef (0x403a4568)->() incrementing from 2. trace:ddraw:GL_IDirect3DImpl_3_CreateDevice (0x403a5380/0x403a5384)->({31416d44-86ae-11d2-822d-a8d53187cafc},0x403a4e28,0x408523d0) trace:ddraw:d3ddevice_create creating OpenGL device for surface = 0x403a4e28, d3d = 0x403a5380 trace:ddraw:d3ddevice_create visual found trace:ddraw:d3ddevice_create context created (0x80a0260) trace:ddraw:d3ddevice_create setting current context err:ddraw:set_context This function should not be called in the current state of the code... trace:ddraw:d3ddevice_create current context set trace:ddraw:d3ddevice_create creating implementation at 0x403a5770. trace:ddraw:create_device_helper returning OpenGL D3DDevice3 (nil) trace:ddraw:Thunk_IDirect3DDeviceImpl_3_EnumTextureFormats (0x403a5774)->(0x405393,0x42e014) thunking to IDirect3DDevice7 interface. ... ** trace for cvs head: ** ... trace:ddraw:Main_DirectDraw_QueryInterface (0x403a4540)->({bb223240-e72b-11d0-a9b4-00aa00c0993e},0x408523cc) trace:ddraw:direct3d_create creating implementation at 0x403a54b0. trace:ddraw:Main_DirectDraw_QueryInterface returning Direct3D3 interface at 0x403a54b4. trace:ddraw:Main_DirectDraw_AddRef (0x403a4540)->() incrementing from 2. trace:ddraw:GL_IDirect3DImpl_3_CreateDevice (0x403a54b0/0x403a54b4)->({31416d44-86ae-11d2-822d-a8d53187cafb},0x403a4f18,0x408523d0) trace:ddraw:d3ddevice_create creating OpenGL device for surface = 0x403a4f18, d3d = 0x403a54b0 trace:ddraw:d3ddevice_create visual found trace:ddraw:d3ddevice_create context created (0x809f818) trace:ddraw:d3ddevice_create setting current context trace:ddraw:set_context glxMakeCurrent 0x80690c0, 62914563, 0x809f818 trace:ddraw:d3ddevice_create current context set trace:ddraw:d3ddevice_create creating implementation at 0x403a55e8. trace:ddraw:create_device_helper returning OpenGL D3DDevice2 0x403a55f0 trace:ddraw:Thunk_IDirect3DDeviceImpl_2_NextViewport (0x403a55f0)->(0x405393,0x42cb40,00000000) thunking ...

Re: Wine 0.9 TODO v0.6
by Z_God 03 Dec '02

03 Dec '02

First, would it be an idea to say at least *insert any number* of Windows apps should be working perfectly with Wine before it is called 0.9? For example, we at least want to have 200 known perfectly working apps. And why not start at version 0.6 or something and calling Wine beta software instead of alpha when these TODOs are done? Then it would be possible to work towards a great 1.0 release. Just look at Mozilla, they post-poned their 1.0 release more than a year to become really great. Keep up the great work!!

Programs to test D3D
by J C 02 Dec '02

02 Dec '02

Hi all, I've been following the recent work on D3D and decided I would give a couple of benchmarks/demos I had around a go. Pleasantly I found that they actually start up now and display some stuff on screen! Before the recent patches they would fail completely when starting the actual D3D stuff. I'm not sure if you're aware of these programs or not but I figured I would pass on the URLs to you as they might be of help. This first is a demo called Bleam: http://www.bluespoon.com/banjoh/ This page has a binary of the demo and source code as well. The second is an older benchmark/demo called Tirtanium: http://www.tirtanium.de/prog3d.html The homepage doesnt seem to have the binary anymore so here's a direct link to a mirror: http://public.planetmirror.com/pub/3dfiles/tweakfiles/benchmark/tirta190.zip Both display stuff on screen and will run through to the end with no crashes. Justin Chevrier PS. Great work guys! _________________________________________________________________ Help STOP SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=features/junkmail

W->A calling and 32->16 calling
by Rolf Kalbermatter 02 Dec '02

02 Dec '02

While going through the shell32 sources I found several issues with respect of this and at least one of them I couldn't find in the Janitorial list. ExtractIconW calls ExtractIconA which is mentioned but ExtractIconA calls InternalExtractIcon16 which is a 16 bit undocumented but exported function. I guess this should also go into the 32->16bit list somehow. I have worked on some fix for this but have to admit that this seems a little bit tricky. InternalExtractIcon16 also tries to open the file name with LoadLibrary16 so if it is a 16bit DLL the requested icons will still be extracted. PrivateExtractIcon and friends which are similar but also can handle negative icon indices which indicates that it should be treated as icon identifier, do as far as I can see not deal with 16bit libraries (they ultimatively call ICO_ExtractIconExW. This of course poses the question if the 32bit function ExtractIcon is supposed to return icons for 16bit libraries and if so, ExtractIconEx may actually also be required to do so. Below is a first attempt for a patch which does most probably not try to load resources from 16bit libraries yet. Also how about going with InternalExtractIcon16? Any comments to this?

Re: Wine 0.9 TODO v0.6

> As a departure from previous release, this time I'm only going > to include a small summary of changes since the last release: > -- A4: New screenshots page is available for comment I looked at the screenshots. Looks very impressive but very problematic.. Why problematic? simple: most of those applications requires many tweaks to run. Example: try to install Office 2k on the latest wineHQ. You'll have lots of problems installing it, and even if you install, you'll need to do "reboot" - which is not available unless you have CrossOver office. Same goes to many applications which have screenshots there.... So think what will happend if users will download wine-snapshot and won't be able to install the apps that appears in the screenshots? lots of anger, flames, false bug reports, you name it ;) Thanks, Hetz

Winelib - MFC application
by Ronald MALLET 02 Dec '02

02 Dec '02

I'm currently trying to build an MFC based-applications using Winelib. I (almost) successfully compiled the MFC, and get an mfc.dll.so file. Here are the few troubles I had or still have: First for compiling the MFC: --------------------------------------- - I had to uncomment PSH_WIZARD97 in /wine/prsht.h - The packing pragmas looks handled by gcc-3.2.1, so we may remove all modifications made by winemaker - I had to force winnt.h to use nameless struct and unions - I added #define EDEADLOCK EDEADLK in /wine/msvcrt/errno.h - I linked _alloca() to alloca() function - There was a conflict on HKEY type between <afxres.h> and <wine/windef.h> - Some little others syntax issues like: __try __expect, asm {}, unsigned short(x), (LPCTSTR)CString ==> it worked then, using some additional defines as suggested in the Winelib documentation page. Then for my MFC-based application: ------------------------------------------------- - Winemaker tries to link with libmfc.so, but by default we have a dll, so i just symlink it to mfc.dll.so - I first tried winemaker default settings on my app, but it creates two targets with the same name (the dll and the executables), so I had to override this using interactive mode - Then I encountered the MFC initialization problems (a crash in dllname() when loading my application .so), so I added the wrapper using winemaker - Even when using the wrapper, it crashes at startup when trying to load my application dll. - The backtrace is something like dllname (from libmfc.so) operator new ... Init (from /gcc-3.2.1/libstdc++-v3/src/ios.cc:211) ___static_initialization_and_destruction_ ... _dl_open ... WinMain (from myapp.exe_wrapper.c:83) __wine_exe_main (from myapp.exe.spec.c:129) start_process call_on_thread_stack - Winelib must have been initialized, but the problem stills here ? Any suggestion ? - I then tried to remove linking with libmfc.so but using only the mfc.dll.so (I had to fill the mfc.dll.spec file to export all the symbols, using weird mangling rules), but it then hook in the msvcrt.dll in an infinite _lock loop ? I'm a bit lost with this error, as it's not in an easy-to-debug code area.... Any advices are welcomed !

I think this statement has to be tightened. I am sure you know exactly what you mean, Alexandre, and I believe that I and many others do. However I think we need to mention that one needs to consider that the strings passed in may be bad, e.g. unterminated. Either one uses that actual measured lengths of the strings when allocating or one checks the lengths of the strings against the allocated space. In particular one DOES NOT allocate on the basis of some wishy-washy documentation statement or a hard-coded constant that the caller may well have ignored. > > -- > Alexandre Julliard > julliard(a)winehq.com > > Bill Medland

How to fix display errors?
by Ferenc Wagner 02 Dec '02

02 Dec '02

Hello, I decided to forward a previous post of mine from the users' newsgroup, since I got no answers there, and consider this a developer question: I'd like to correct some bugs. Having read the Developers' Guide didn't help me much: the relevant topic was empty (the program runs, but shows some errors). Perhaps you can point me in the right direction (I mean: source file in the tree)? Below is the article. See a screenshot at http://afavant.elte.hu/~wferi/wine.png (25K). It exhibits several slight problems. 1. The scrollable list has no border (Suchanfrage window, above the Phrasensuche checkbox). 2. The text input field (with Goethe in it) has no border, too. 3. The "Minimize" button is misplaced: clicking to the right of it invokes its action, the button itself is not clickable. 4. The little toolbar window to the right looks strange, but what is worse, it is sticky: appears on every viewport (It's not managed by fvwm2, like the main window.) The Suchanfrage subwindow is not sticky. While executing the program, I get the following messages: err:toolbar:ToolbarWindowProc unknown msg 0465 wp=0000004c lp=412c1d70 fixme:accel:CreateAcceleratorTableA should check that the accelerator descriptions are valid, return NULL and SetLastError() if not. fixme:mdi:MDIRefreshMenu partially function stub fixme:mdi:MDIRefreshMenu partially function stub err:statusbar:StatusWindowProc unknown msg 0486 wp=0000 lp=00000000 err:toolbar:ToolbarWindowProc unknown msg 0486 wp=00000000 lp=00000000 fixme:accel:CreateAcceleratorTableA should check that the accelerator descriptions are valid, return NULL and SetLastError() if not. fixme:mdi:MDIRefreshMenu partially function stub fixme:mdi:MDIRefreshMenu partially function stub fixme:mdi:MDIRefreshMenu partially function stub fixme:mdi:MDIRefreshMenu partially function stub fixme:mdi:MDIRefreshMenu partially function stub Is there anything I can do about the above (cosmetic) errors? I use a recent CVS checkout (Wine 20021125), and I know C programming, but have no experience with graphics and Windows. Feri.
