I'm sorry I asked this here, but the only help I got from the FAQ was: ------ Q: How can I detect Wine? A: You really shouldn't want to do this. If there's a quirk in Wine you need to work around, it's *much* better to fix it in Wine (after all you're a developer, so you should be able to gather enough help and knowledge to fix it for real). If you think you really want to know how to detect it anyway (maybe in order to just have a cool "running on Wine" status text or so), then please mail me.

Oh sure, you CAN detect Wine if you want, the point is that the Wine project reserves the right to change any behavior at any time for any reason, but most often in order to try to make some application more compatible with Windows. If this breaks your Wine detection, tough. We will not change back because of you. So that is why there is no OFFICAL way to detect Wine, simple because if where was an offical way people could quite reasonable complain if some change to Wine broke their detection. However since there are no offical way, they can't complain can they? :-)

Whats done? not?
by Christensen Tom 25 Oct '02

25 Oct '02

Obviously wine is still being actively developed, and I know its not close to "done" however, I want to get involved, I know C/C++ and have a pretty good grasp of windows apis, I'm just wondering is there a place (kinda like in the Mono project they have a tree laid out with all of the classes/functions that are in the .NET runtime, and they have them marked done, being worked on, not started...) So I'm wondering if wine has anything similar? or should i just pick a function, and see if its done already by searching through the source? At any rate, wine should have a nice concise place to look and see if wine has certain functions implimented.. Tom _________________________________________________________________ Broadband?

hack to make GrandPrixLegens and N2002 work
by Christoph Frick 25 Oct '02

25 Oct '02

Hi! This is an more or less a straight forward hack to make the game grand prix legends work. It will also effect other games from Papyrus. The game has two problems: 1) It binds more than one time to the same port without doing an SO_REUSEADDR. Acording to UNP it is no big deal to do so - so i just force it. 2) The game sets SO_DONTROUTE on the socket. This works in linux and prevent the user of connecting to games in other networks. Either windows ignores the SO_DONTROUTE or it is not set in native windows or it is ignored. I dont have any opportunity to find out. Another thing is a registry key the game expexcts: [System\\CurrentControlSet\\Services\\Class\\NetTrans\\0000] 1027876728 "IPAddress"="192.168.66.6" It runs with this setting (also N2002); maybe the dontroute problem could also be solved, if the remaining keys to properly define the TCP/IP config for a NIC in windows are set?! So my plea: Could some windows network/socket guru point me in a direction to do further investigations? BTW: i can not imagine this "patch" makes it to the tree - but just to have it said: The patch is under BSD License. CU!

Re: avoid XF86DGANoDirectVideoMode while detecting no dga

Grmbl, I must have missed that case when I submitted my fix last time (I only did it in the actual DGA2 usage, not in the 'probing' code). The actual root cause is (for me), a 'feature' in the X server that, instead of reporting the extension as missing on remote clients, report it as being present but then send error messages when trying to use it.

Services
by Martin Wilck 25 Oct '02

25 Oct '02

I have had a look at dlls/advapi/services.c and found that it is pretty incomplete. Can anybody tell what the current implementation is used for (are there any known programs starting services?) In particular I'd like to know what people generally think about the usefulness of Services in Wine. The fact that wine cannot change user personalities and is lacking most of the NT security concepts makes services pretty useless. However it may be desirable to translate services into something useful on Unix, especially for winelib (it would be useful for the app I am trying to port). Has there been a discussion yet how to set this up without compromising system security?

eTax status report
by Ben Stanley 24 Oct '02

24 Oct '02

Hi, I have now completed using the eTax program from the Australian Taxation Office (http://etax.ato.gov.au) under wine, and have some concluding remarks. * Yellow Note Popups over buttons: these notes pop up almost immediately you put your mouse over a button, and if you click on them, the button does not respond. This causes great user frustration, as you point the mouse at a button, click the mouse, and nothing happens because the popup note appeared and stole the mouse click. Perhaps this could be solved by moving the popup note position so that it's not directly under the mouse pointer? I don't know if this is an etax problem or a wine problem. Workaround: move mouse over button and click again, or be very quick with your mouse click the first time. * ListView (tree): when hovering over items with long names, the same popup note appears, and also greedily steals mouse clicks, preventing you from selecting the item underneath. The note must pass the mouse click through for proper handling by the list item. Workaround: Wait for popup to disappear and then click on list item. * I had some refresh issues with the print preview section of the program. When it draws a page for the first time, all form fields appear to be filled in correctly, but when scrolling the form fields are often left blank when they should be filled in. This may be verified by going forward and then back a page, to force a complete re-draw of the original page, and verifying that fields which were previously blank are now drawn properly. * I didn't try to submit the tax return under wine, as I did not know about the wine integration of the web browser which would be used to perform the submission. (I failed to download the security codes under Mozilla, so I resorted to a Windows box for downloanding security codes and submission.) * Help problems, partly to do with launching winhelp from within etax, and also partly because WINE help can't yet read the etax help file properly. I used etax in the desktop windowing mode, as I had problems with both the managed and unmanaged modes. I set all dlls to builtin (except for "*"). This is the first year that I have been able to use eTax to do the tax return. I want to thank all of the wine contributors for making it possible! Last year I gave up and used a Windows box for the whole thing. Ben Stanley

I knew that much already ;) But if wine is to run as a "service" (i.e. load at bootup via an initscript) and acutally be functional as well as user-friendly, it will have to run in it's own account, just like apache and pgsql do and like i believe named does... -Dustin __________________________________________________ Do you Yahoo!?
