I wasn't able to find any documentation on how the detection works in /documentation. Something is lacking as ie6 setup runs fine if if a version is set and complains about not having a current windows version if not. It might be reading a key that doesn't exist by default, maybe //software//microsoft//windows nt//current version although I didn't capture the trace after I set [Version].

WM_{ERASEBKGND/PAINT} <-> ScrollWindowEx race
by Dimitrie O. Paun 01 Oct '02

01 Oct '02

Hi folks, Some time ago I reported a drawing problem that appeared often in the Common Control Spy. The reason it happens there, is that that application has a listbox which lists messages, and notification received/sent by the control. Well, this listbox scrolls automatically (quite fast at that) as there are quite a few messages/notifications sent, and if you obstruct it partially with a dialog box that you drag around, you can easily replicate the bug. What happens is that a part of the dialog's caption is scrolled up, and not erased. I've attached a snapshot of the problem -- please take a look at it. I was thinking about it, and I think I know what the problem is: 1. you drag the dialog box down 2. this invalidates a portion of the listbox (this invalidated portion contains part of the old caption of the dialog) 3. for whatever reason, the listbox gets new items, and is scrolled (using ScrollWindowEx), *before* it gets a WM_ERASEBKGND/WM_PAINT message. 4. ScrollWindowEx scrolls the content of the window *including* the invalidated area which contains the portion of the caption. *5. ScollWindowEx fails to extend the "scroll" update the portion of the update region (wndPtr->hrgnUpdate). As you can see, the bug happens at step5. That is, if we scroll a rectangle that intersects the update region, we have to "scroll" the update window as well (in the portion that it intersects). For example, say we have a simple update region: [0,50,100,100], and we scroll the rectangle [0,0,100,60] by 30 units up, we have to end up with an update region of [0,20,100,100]. I don't think that we do, right now. Can anyone familiar with the code (dlls/x11drv/scroll.c) take a look, and see what's going on? -- Dimi.

[Version] in ~/.wine/config

Any reason why we don't default the windows version to something recent like Win2K and let the user change this to an older version if necessary? Chris

So long, and thanks for all the fish!

Hello All, Unfortunately I need to stop most of my work on Wine. This is due to family demands and also that it is not fun anymore. I would recommend that Dimitrie Paun to take over the Common Controls. He has done a great deal of work on them and deserves the honor. I may continue to "lurk" on the lists but do not forsee any activity. Good luck all, and thanks for the friendship. Guy Albertelli <<galberte(a)neo.lrun.com>>

Fix: Anti-aliasing for font sizes >8
by Dag Wieers 01 Oct '02

01 Oct '02

Hi, I noticed recently that Wine was able to do anti-aliasing for font sizes >16 although my Gnome 2 looked nice with anti-aliasing of <16. I started to look why Wine apps were only anti-aliased for >16, and I came across this: --- dlls/x11drv/xrender.c.orig 2002-09-29 12:56:27.000000000 +0200 +++ dlls/x11drv/xrender.c 2002-09-29 12:56:56.000000000 +0200 @@ -322,7 +322,7 @@ assert(entry->nrealized == 0); - if(antialias && abs(plfsz->lf.lfHeight * plfsz->xform.eM22) > 16) { + if(antialias && abs(plfsz->lf.lfHeight * plfsz->xform.eM22) > 8) { pf.depth = 8; pf.direct.alphaMask = 0xff; } else { When I changed this, my Notes was much nicer to work with. I presume there is a reason why anti-aliasing was off, but I would reconsider that decision.

Re: patch to MZ_Exec() PE executables
by Jukka Heinonen 01 Oct '02

> Look reasonable? No. Command tail is not null terminated so you cannot use strlen. DOS exec function "load and exec" is synchronous so you should return to caller only after created process has finished. In addition to hFile lead found by Ove Kaaven, you are leaking handles in PROCESS_INFORMATION. Using fixed size buffer for full command line without sanity checks is a bad idea and will cause problems sooner or later. And, finally, you are ignoring long command lines from DOS program stored in CMDLINE environment variable. (I have already exchanged private email with Chris Morgan about this; DOS programs can be passed command tails longer than 126 characters using CMDLINE environment variable. Similarly, DOS programs may pass long command lines to programs they execute.) -- Jukka Heinonen <http://www.iki.fi/jhei/>
