At that point, hDC should be a HDC, if it's not, you have to modify the code around it. Such casting should happen in the WindowProc, all functions should work with the proper type. Alexandre, please do not apply the patch in this form: it silence warnings, and it makes it very difficult to properly correct the code in the future. -- Dimi.

Re: interrupts in when in NT version

I have forgotten to cc this discussion to wine-devel. But who is interested can catch up from this mail.

The reason is that additional info is needed for a proper fix. Safedisc depends on that EXCEPTION_ACCESS_VIOLATION is returned on an int 0x01 call. But it should be checked what exceptions are raised on different windows versions when int 0x01 is called. And maybe the same should be done with other interrupts. It would be good if somebody could make that test program. Else I will keep the non proper fix. > > > it was allowed on Win9x, and is used in this context IIRC as a ring 3 > > > to ring 0 transition code (how to create a cheap call gate) > > > > How good it would be if I could understand what you are speaking about :( > > But could you explain what a call gate is? > > If it is too long, then dont bother tough... > > I'll try to make it short > context: > - i386 have 4 levels of privilege => ring 3 (less privilege) up to ring > 0 > - certain operations are only allowed at ring 0 (or 1) > - user code runs in ring 3 > - kernel code runs in ring 0 (to be exact, NT had been designed to have > kernel in ring 0, and device drivers in ring 1, but this has been > altered - some drivers run in ring 0 too) > - you can always call into a less priviledged level (ring 0 => ring 3 > for example) > - the other way around requires what is known as call gates (ring 0 for > example defines the "entry points" in some way) > - most of the interrupt handlers run in ring 0 > > what the safedisc code was doing was: > 0/ code is running in ring 3 > 1/ install an interrupt handler for division by zero (IIRC) > 2/ trigger the division > 3/ have the interrupt handler called, but this is done in ring 0, even > if the code has been loaded from a user space program. here, in the > interrupt handler, you can do any ring 0 operation you want > > that's why I called it a cheap call gate (no real call gate has been > installed, and the code run in ring 0 isn't decided by the kernel but > the app) > > NT doesn't allow this to run. step 1 is not allowed (only the kernel can > decide to change an interrupt handler, which makes lots of sense) Thanks for the detailed explanation.

Loading program icon
by Peter Andersson 26 Oct '02

Hi, How do you read the icon of a windows application? Please tell me how to do it inside wine/windows-environment, and possibly independent of wine/win (the raw way). Can someone give me a hint? //Peter

I haven't been updating my machine at home, which had the patches applied, so I thought the patches were not in CVS. I will do a cvs up -C and rebuild here at home, and see what I get.

Status Report: -DSTRICT
by Michael Stefaniuc 25 Oct '02

25 Oct '02

Hello, status reports seems to be pretty popular this day so here is mine regarding compiling wine with -DSTRICT. Below is the amount of warnings we get when removing -DWINE_NO_STRICT: dll real total ------------------------------ commdlg 21 63 gdi 128 273 ntdll 148 178 ole32 16 38 shell32 120 155 user 450 839 winmm/wavemap 7 40 winmm 104 145 winsock 14 42 x11drv 60 79 ------------------------------ total 1068 1852 "real" is the number of warning for which real work is need to be done, the rest up to "total" are warnings of the type "int format, HANDLE arg". And to fix this beasts just grab http://people.redhat.com/mstefani/wine/fixpointerarg.pl and do: cd wine/dlls/$dll_in_work make clean make 2>&1 | fixpointerarg.pl and you should be done. Happy hacking bye michael P.S.: a request from Eric: please let him finish the 32bit - 16bit separation of winmm. After that is yours. -- Michael Stefaniuc Tel.: +49-711-96437-199 System Administration Fax.: +49-711-96437-111 Red Hat GmbH Email: mstefani(a)redhat.com Hauptstaetterstr. 58 http://www.redhat.de/ D-70178 Stuttgart

Re: Listview Z0 (roll-up patch)
by David D. Hagood 25 Oct '02

For those of us who are a little behind on the patches, would it be possible to get a roll-up patch of all diffs from the CVS MAIN branch? Also, what is the status of CVS vs. the patches - what patches have been applied?

Re: Known listview bugs (take 2)
by Jeff Smith 25 Oct '02

25 Oct '02

Just a couple of days ago, the problem with native (W95-OSR2.1) regedit was that changing keys in the tree kept piling up new items in the listview. It was quite interesting seeing multiple (Default) values for a key :-). Now (12 hours ago anyways) it is always blank. When I click on where the values should be (highlight them), sometimes they will show up then. It seems something is not being refreshed that should be. Maybe I'll get a chance to dig in later today if nothing has been uncovered by then. -- Jeff S. >From: Greg Turner <gmturner007(a)ameritech.net> > >On Friday 25 October 2002 07:35 am, Dimitrie O.
