Anyone know anything about this function? I stubbed it to get around an occasional crash in native common controls, but I'm not positive the function signature's correct. --Juan __________________________________ Do you Yahoo!? Yahoo!

Can you create a testprogram? If not then I can send you one. Just create an empty form and place the SSTab on it (the one from tab control, not the one in the standard palette). This fails on on my computer and I don't know how wine could detect if it's a headerless picture or no picture at all if they look the same (so far). Thanks bye Fabi

Re: Sourceforge WIne RPMs and Yum
by Dwayne Bailey 03 Feb '04

03 Feb '04

Hi, Are there any yum experts here? I thought it would be a good idea to get a yum repository established for the Wine RPMs held at sourceforge. I for one would love to have the latest build of wine installed as soon as RPMs are available on Sourceforge. yum-arch seems to be the command to create the repository headers but I'm not sure how you would manage this with the round robbin sourceforge downloads. I think some other sf project have managed this. Anyone out their who can help? Dimitrie O.

Re: Wine 0.9 TODO

On February 3, 2004 02:56 am, Lars Segerlund wrote: > I am curious about 'testing daemon to run as windows service' [I'm Cc:-ing wine-devel, other may be interested in this as well] This TODO item has nothing to do with running services under Wine. What this is instead is a real Win32 service for Windows. The purpose of this service is to help us automate the running of our conformance test suite under Windows. It's operation should be very simple: once installed, it has to poll (say every 1h) a location on winehq.org to determine when new tests are available. When they are, it has to download one executable (winetest.exe), and run it (winetest.exe -b). That's it. This way, people that want to help us test, can simply install this service, and go by their business. Needless to say, we need a volunteer for this... No Unix experience required, this is purely a Win32 little app. Nice way to get started :) -- Dimi.

WineConf update
by Vizzini 02 Feb '04

02 Feb '04

After a slippery drive home (12 stressful hours from Minneapolis -> Kansas City, rather than the six it took me to get there on Friday), I finally have time to report a bit on WineConf. First of all, I'd like to thank Codeweavers on behalf of those of us from ReactOS that attended the conference. It was really run well, with ample free food (always a requirement). I didn't even mind -5F as much as I thought! There were about 35 Wine and ReactOS hackers there, and two days worth of presentations. I started getting serious questions about ReactOS the instant people figured out who I was. There was about a 50/50 split between people wanting to know what it was and people wondering why we are bothering to do this. There were a lot of interesting (and passionate) conversations about the role of Linux on the desktop, the stupidity of trying to clone the windows kernel, intellectual property considerations, etc. I can say that in all cases, the discussions were very positive and open. I'm certain that I didn't convince everyone, but just the opportunity to make the case was worthwhile. The ReactOS presentation on Sunday morning went as well as can be expected, given the state of our code. I spoke from a prepared deck (http://plasmic.com/~vizzini) for about 15 or 20 minutes, and then we demonstrated various aspects of the system. Steven ran the demonstrations, which included showing off Explorer, Windows XP Notepad, and our installation system. Then, the four of us (Steven, Art, Mark, and me) took questions. Most of the questions this time around were very technical in nature, and there was at least one question (from Gavriel State, regarding our DIB engine), that pretty much stumped us (can one of the UI guys please comment?). We had two crashes due to the floppy driver (well, also due to my stupidity at not configuring VMWare with a blank floppy disk image before starting), and one non-detected mouse incident. There was also a bit of a repainting problem, but on the whole, the system represented itself well. There was a very interesting question brought up on Saturday morning by one of the Wine guys (Mike perhaps?) regarding running ReactOS inside Linux, like Win4Lin. I was skeptical at first, but having slept on it a day or two, I think this is a really cool idea. The proposal is that we adapt our own ntoskrnl.exe and hal.dll to run correctly in user mode, just like user mode linux does, and use them to run the rest of a native Windows XP system. In other words, it replaces Win4Lin with free software, and it would be compatible with the current Windows OSes. Much investigating remains to be done, of course - I can't really even guess at the level of difficulty or time required at this point - but it is worth pursuing in my opinion. Jan Kratochvil also joined us to present about his Captive NTFS project. For those that don't remember what this is, Jan got the ntfs.sys driver from Windows XP running in Linux, in part by using chunks of ReactOS code. Jan and I had some offline discussions as well about bringing Captive's improvements back into our tree, and about other captive-like projects that could be implemented. I expect a lot of focus will be applied to this area of Quasi-Wine, Quasi-ReactOS hacking over the next year. All in all, it was a really great conference, and I'll definitely try to attend again next year. Presentations were good, conversations were interesting, people were friendly, and Minnesota at -5 was beautiful! ;-) -Vizzini

I don't know if you have seen this before, but it's a program to run the grafix pipeline interactive, thought it might be usefull. http://mirror.ati.com/developer/sdk/rage128SDK/Multex/Multex3D.html / have a look, Lars Segerlund.

TransparentBlt
by Kevin Koltzau 02 Feb '04

02 Feb '04

Implementation of TransparentBlt This brings up an interesting thing however..it works perfectly under windows (tested on XP), but produces strange results under wine. MaskBlt seems to be broken, but I'm not quite sure what the cause is yet I figured I'd send this out incase the problem is obvious to anyone
