Duplicate StrRetToStr function in commdlg
by Francois Gouget 01 Nov '01

01 Nov '01

Yes, yet another duplicated StrRetToStr function: COMDLG32_StrRetToStrNW in dlls/commdlg/filedlgbrowser.c. At least this time it says that it's a copy. I guess it would be better if the implementations were pointing to each other. It would at least make it easier to maintain. But this case is not as easy as the shell32 case: * first the implementation is slightly different: the SHFree is not commented out in this one. I don't think the difference is intentional. So who is right? * commdlg is not supposed to import shell32. But it already imports a couple of other functions from shell32 so why not this one? It would be better than have another inconsisten implementation. * except that StrRetToStrNW is not exported. It is StrRetToStrN which is exported. So is it ok to call StrRetToStrN? Is StrRetToStrNW really more correct? Well, here is a proposed patch that imports StrRetToStrN from shell32 via the already-in-place GPA mechanism and removes COMDLG32_StrRetToStrNW.

LockFile - any words of warning?
by Bill Medland 31 Oct '01

I am going to have to implement the LockFile/UnlockFile functions. Does anyone have any words of warning? (Like it ain't as easy as calling fcntl) Bill

Can you try the attached patch? I did and it does not change anything. I don't quite see how it could, since it does not seem better to not initialize data than initialize it to a wrong value :-) I tried ff0000/ff00/ff instead, with better success... Gerard

double key events
by Arjen Nienhuis 31 Oct '01

31 Oct '01

I test wine often with a game called Elastomania. Wine gets better over the years, but there is one problem that remains when playing that game: In the menus the cursor moves two positons on a key press. The biggest problem is that most of the menus have an odd number of items, so half of them are not reachable. This happens with all the versions of wine I have tested on al the platforms I tested it on. The game uses directx. The problem is not in that both the keyup AND keydown events are being interpreted, because the cursor moves twice at keydown. The cursor does not repeat when a key is held down longer. My not so very usefull guess is that the program tries to shut down some sort of messaging, but that doesnt't work with wine, and the program still listens to those events, and recieves them. Where do keyboard events go? this is the output when ran with no cmdline options: Could not stat /mnt/fd0 (No such file or directory), ignoring drive A: fixme:ddraw:Main_DirectDraw_SetCooperativeLevel (0x40464254)->(00000000,00000008) fixme:ddraw:Main_DirectDraw_SetCooperativeLevel (0x40386af8)->(00010021,00000013) fixme:x11drv:X11DRV_DDHAL_CreatePalette stub fixme:x11drv:X11DRV_DDHAL_CreatePalette stub fixme:x11drv:X11DRV_DDHAL_CreatePalette stub err:dinput:SysKeyboardAImpl_Unacquire \ Unacquiring a not-acquired device !!! here is a summary of the output when ran with: --debugmsg +key,+keyboard,+dinput it starts with tons of: KEYBOARD_MapDeadKeysys no character for dead keysym 0x00XXXX and X11DRV_KEYBOARD_DetectLayout matches=47, mismatches=0, score=94 X11DRV_KEYBOARD_DetectLayout Attempting to match against "United Sta... blablabla... then: X11DRV_InitKeyboard fixme:ddraw:Main_DirectDraw_SetCooperativeLevel DirectInputCreateA IDirectInputAImpl_CreateDevice keyboarddev_create_device Creating a Keyboard device (0x40464288) then tons of: IDirectInputDevice2AImpl_SetDataFormat then: IDirectInputDevice2AImpl_SetCooperativeLevel \ (this=0x40464288,0x00010021,0x00000006) DISCL_FOREGROUND DISCL_NONEXCLUSIVE it then does very often: X11DRV_MapVirtualKey ... wMapType=1 and uses the return values in: GetAsyncKeyState () which is always: -> 0 and then (at line 25711)...

As in many cases, Wine does not work because it is not tolerant to strange parameters Actually the dib masks are all equal to 0. Probably the correct fix is to assume an 'asis' (not reversed) conversion when the app does not set any mask. Gerard

Windows would be nice (you just need to call the wine server request to create from a unix fd into a windows handle and wait on it.

Anyone compiled Borland OWL (Object Windows Library) with winelib ?
by Grzegorz Prokopski 30 Oct '01

30 Oct '01

Hi ! I am unable to find this information in wine-devel archives, so I decided to ask here. Q1: Have You heard about anyone who compiled Borland OWL (Object Windows Library) based project with winelib ? Yeah - I know it is an old library and Borland C++ 5.02 is the last version released a few years ago and without future updates. Anyway I have a project which IS written in OWL and need to check how hard will it be to make it working under Linux without rewriting it all. I belive I have the sources for complete OWL of course. Q2: With You expirience what would You say to that statment: If my OWL-based program works under Wine it should be convertable to winelib. How true is that statment ? Q3: I have read docs about using winelib and seen that there is MS Visual C++ mentioned many times. Does MS VC++ have some kind of support in winemake or in winelib itself ? Does OWL case differ much from MS VC++ ? Thank You for Your answers. Grzegorz Prokopski
