Help fixing updown (comctl32) bug?
by C. Scott Ananian 13 Mar '05

13 Mar '05

I have an open-source Windows application I'm trying to get to run under Wine (sd -- it's in the wine applications database). The particular issue I'd dealing with (at the moment) is a UDM_GETPOS message to an updown control. This is the code in the source application. ui_options.sequence_num_override = SendMessage(GetDlgItem(hwnd, IDC_SEQ_NUM_OVERRIDE_SPIN), UDM_GETPOS, 0, 0L); Under windows, when you just click 'ok' on the dialog without touching the updown control, this SendMessage returns '0'. Under wine, it returns 65536. Looking at the code (wine-cvs/dlls/comctl32/updown.c:2049): case UDM_GETPOS: temp = UPDOWN_GetBuddyInt (infoPtr); return MAKELONG(infoPtr->CurVal, temp ? 0 : 1); So, the different between Windows and Wine is that 'GetBuddyInt' (or its equivalent on Windows) is returning TRUE on Windows and FALSE in Wine. Digging down a level, the first lines of code in UPDOWN_GetBuddyInt are (wine-cvs/dlls/comctl32/updown.c:267): static BOOL UPDOWN_GetBuddyInt (UPDOWN_INFO *infoPtr) { WCHAR txt[20], sep, *src, *dst; int newVal; if (!IsWindow(infoPtr->Buddy)) return FALSE; ------- tracing through GetBuddyInt in Wine, this is as far as it gets. IsWindow returns FALSE, and so GetBuddyInt returns FALSE. But this is very puzzling: if I click one of the controls on the updown control, GetBuddyInt will eventually return TRUE. I don't really understand the purpose of the 'IsWindow' call here -- can anyone who understands the code a bit better explain to me how infoPtr->Buddy could get 'de-windowized'? I don't see anyplace in the code where Buddy gets reassigned, and turning on tracing doesn't show anything suspicious, and I've having great trouble getting gdb to set an appropriate watchpoint for me. Does anyone else have any insights? --scott KUCAGE KMPLEBE class struggle Cocaine UKUSA SCRANGER early warning colonel Bejing AELADLE LICOZY for Dummies ammunition ESODIC Treasury ( http://cscott.net/ )

Winston.exe or Elster-Formular
by Dietrich Teickner 13 Mar '05

13 Mar '05

Has anyone tested "Winston" with wine ? This is a replacement for the german tax-program "Elster". If yes, how does the internet-connection works ? Inside Odin(wine-for os\2) overwrites any os-function the WSALastError ( redirected LastError) with any LastError. I know Wine works in the same manner. After redirect the WSALastError to any Tls (only for test), "Winston" will work. Dietrich

What you mean is we can drop a .menu file into ~/.config/xdg/menus/applications-merged and it'll be automatically linked in. We can do this in wineprefixcreate (or when the first menu entry is created). > 2) Create some Wine .desktop files that can go > in /usr/share/applications that will be readable by this menu entry. > These will be for system-wide Wine apps that are common to all users. > This will include Wine's own apps (like the configuration tool and the > uninstaller) as well as packages which depend on Wine (such as > Winetools). If we're going to create our own submenu to map the start menu we may as well put stuff like winecfg and the control panel there.

We basically need to ensure it still works (probably hasn't actually worked properly for ages) and then merge the start menu directory in using the <LegacyMenuDirs> element. > These files can be kept up to date > (such as when a user installs a new windows application) by the > wineserver program.

Menu entries are created on the fly by the shell linker interface. GNOME monitors the menu directories/files so when they change it can reload the definitions (in theory, in practice this is broke on quite a few distros). > 4.)

Again, observe that programs can place launchers onto the desktop (which you can then drag to the panel etc). thanks -mike

Borland C++ Buildeer under Wine

Below is the last three lines of error messages printed when I tried to run Borland C++ Builder under wine. (There were pages and pages of error messages after I hit Ctrl-C in the terminal I had started BCB.EXE from.) Is this a known bug in Wine ? err:syslevel:_EnterSysLevel (0x40797840, level 2): Holding 0x4083ccc0, level 3. Expect deadlock! err:syslevel:_CheckNotSysLevel Holding lock 0x4083ccc0 level 3 err:seh:setup_exception stack overflow 176 bytes in thread 0009 eip 004078d5 esp 405b0f50 stack 0x405b0000-0x406b0000 [andrew@zeus BIN]$ -- Andrew [hackcoughsniffle] Internal Virus Database corrupt
