ownerdraw paint recursion in listbox
by Alexander Yaworsky 04 Aug '05

04 Aug '05

Hello, recently i tried to install some application and it hung when i tried to select options. It uses listbox with ownerdraw items with checkboxes. When listbox is initially painted everything is ok. But when i try to select other item, an extra WM_PAINT is sent to listbox when application draws item. This causes infinite recursion. I've been implemented a simple workaround adding boolean to listbox structure but i have doubts. I briefly looked at some other controls and had not noticed similar countermeasures. Have somebody ever seen such behaviour? It would be interesting to test other controls sending WM_PAINT from ownerdraw handler but i'm short of time to do it soon. Should this workaround implemented in this way or something is wrong deeper with WM_PAINT handling? Thanks.

rpcrt4.dll NdrGetUserMarshalInfo() problem
by J. Grant 02 Jul '05

02 Jul '05

Hello, I am getting the attached error when running an install of Overnet v0.52. Basically it cannot find NdrGetUserMarshalInfo(), despite it being in the dll at entry point: 77d43452h, order 199. Any ideas what this problem could be? I'm expecting this to be the symptom of some wider problem. Any help appreciated. Kind regards JG p.s. Is there any way to get these mangled function names to be displayed un-mangled please? c:\opt\overnet_0_52>overnet c:\opt\overnet_0_52>err:module:import_dll No implementation for MSVCRT.dll.??_U(a)YAPAXI@Z imported from L"C:\\opt\\overnet_0_52\\MSVCIRT.dll", setting to 0xdeadbeef err:module:import_dll No implementation for MSVCRT.dll.??_V(a)YAXPAX@Z imported from L"C:\\opt\\overnet_0_52\\MSVCIRT.dll", setting to 0xdeadbeef -- Homepage: http://jguk.org/ Blog: http://jguk.org/index.html#blog Radio: http://jguk.org/index.html#radio

lotus notes regression
by Paul R Streitman 25 Jun '05

25 Jun '05

Patch 14725, applied 2004/12/07 11:31:53, breaks lotus notes. The symptom is a hang with the CPU at 100%, and it happens immediately if you try to click on a notes 'bookmark', or shortly after you try to do much of anything else if you try to avoid the 'bookmarks'. Sorry that it took me so long to report this, when I decided that it wasn't just a temporary instability I eventually had to iteratively compile (many) CVS snapshots to narrow down when the problem was introduced because I found it impossible to untangle the various patches that went in around that time frame. I also ran afoul of the jack problems near the end. I do not know how to narrow the problem down further. I tried running winedbg (at CVS level a couple of days ago), and that seems to be broken too -- it wanted to run things from the wine build tree? There are no unusual console messages or anything when the problem happens. Thanks, Paul z/OS core components development Internet: prs(a)us.ibm.com

Support for IDvdInfo2::GetDiscID
by James Courtier-Dutton 25 Mar '05

25 Mar '05

The Windows api method uses the function call IDvdInfo2::GetDiscID http://msdn.microsoft.com/archive/default.asp?url=/archive/en-us/directx9_c… This returns a unique 64bit ID for a DVD. Has anyone found out what exactly it does to create this 64bit ID. It would be nice to get linux DVD players to be able to use the same method. Cheers James

The new code should be exactly the same as the old, barring any side effects from SetWindowLong (which shouldn't affect the control anyway since this the function changed is the handler for WM_NCCREATE).

text edit box not painting text ( on form startup )
by Doug Herbert 09 Mar '05

09 Mar '05

( I have posted a similiar question in wine-users, don't flame me for doing so, just thinking about this some more, perhaps it may be more a developer question ) Ok, I have a windows app, that runs under wine fine - not quite. This app has a form, with many text field edit boxes on. Quite often these edit boxes already have text values, ie. they are not empty - there is a database behind the form. Anyway, the form shows on the screen, but the text within the edit fields is invisible, until you activate each edit box component. When you leave one edit box to the next, the text remains visible. It seems like the repainting is not working, on initial startup of the form. As a way to debug this database app ( I don't have the source code for it ) I wrote a real basic form app in Visual Studio, with two edit boxes, with data in each. Now this basic app shows the text values immediately on startup. So there must be something different that the database app is not doing. I then ran wine using 'wine --debugmsg +edit programname' for both app's. I see both logging 'Creating ANSI edit control, style = xxxxx' but the style reference is different between apps - I am not sure if this the cause or not. The problem app reports style = 54011104 and the basic app shows style = 50010080. Can somebody explain what this style reference means and how do I force an app to use a certain style of edit box ? What other wine class debugmsg types should I use to narrow down the source of this problem ? Is there anyway I can check to see how the database app is repainting text within the text edit components ? Regards Doug Herbert. __________________________________ Do you Yahoo!? Yahoo!

Restart from the ptracer is done with PTRACE_SINGLESTEP. (BTW: I also CC:ed wine-devel ML, that might be of interest to them too) A+

Hi Con, One thought that occurred to me, and this is just a random theory, is that maybe the issue is not with the Wine code but the Win32 code run on top of it. Do you know how 2.6 scheduling compares with 2.4 and Windows (NT) scheduling? Could it be that some apps are written to expect Windows-style scheduling and fail to work if they don't get it? In case you hadn't noticed, I'm afraid I only have first-year CS knowledge of scheduling :/ thanks -mike

Fwd: Foobar2000 audio player Regression

I originally posted this to the -users list, but I was contacted by Robbert Xerox, who had the exact same issue, and thus far nobody has replyed in the users list, so maybe it will get more attention here. > Foobar2000 worked virtually perfectly in the 20041019 > release (aside from some comctrl32 repainting issues > -- which native comctrl32.dll fixed), but in 20041201 > it is completely unuseable.

I have since found out that if you use a the builtin comctrl32.dll, none of the window repaints at all. In previous wine releases, using the builtin comctrl32.dll would just create minor glitches (ex. the status bar wouldn't update). __________________________________ Do you Yahoo!? Yahoo!

another build problem on current cvs
by Joris Huizer 08 Jan '05

08 Jan '05

Hello, For the past week or so, building from cvs on a debian/stable system w/ alsa installed (using a custom kernel Linux debian 2.4.18.041216) breaks on alsa-specific code in wine; I attached the log; note that I did a `cvs update -dPA` and `make distclean` so this can't be any problem with the source I have Any ideas? Maybe you can point me to a place where I can read how to fix this properly (I never worked on alsa-specific code before...) or something like that regards, Joris
