2007/9/3, Misha Koshelev mk144210@bcm.edu: Hi everybody,
So as you all know I've been working on various bug fixes throughout wine, with my most significant contributions to date being MSI OLE automation support and implementation of http protocol support in urlmon. This involvement was driven by my initial experiences of getting a key program used by molecular biologists, Invitrogen's Vector NTI, to install on wine with a fairly convoluted shell script and submitting my first patch to fix a crash with this program; Dan Kegel helped me iron out this first patch a lot and furthermore his comments about how it'd be nice if such a complicated shell script was not necessary with wine got me started with my other patches and the rest, as they say, is history. So why, you may ask, am I sending all this in an email to wine-devel? The short answer is that this is a shameless email to see if I might motivate someone to work on our winhelp implementation a bit, as it is currently completely useless with Vector NTI. This seems like a fairly significant task, and my obligations at school/work have recently kicked up quite a bit, making it unlikely I will be able to take it on anytime soon. However, I hope to motivate someone with these reasons: (i) I feel like I've certainly been doing (and will continue to do) my part in helping out wine, and if this in any case motivates someone looking for a development direction I would certainly not object; and (ii) My ultimate vision/goal has been to have Vector NTI run so well that I could approach Invitrogen and see if they might at the very least say something to that effect on their Web site ("add wine + linux as a supported platform"), if not package Vector NTI a la Google Picassa, which would be great publicity for wine. Also, as you can see from the comments on my ubuntuforums howto http://ubuntuforums.org/showthread.php?t=347095 for a lot of molecular biologists, Vector NTI is the only reason they have to dual-boot/use VMWare at all (full-disclaimer: this is not 100% true for myself). So you could help perhaps a fairly small but non-insignificant group of people by doing some work on winhelp. Although Vector NTI is a rather large set of programs, currently I believe the only things keeping it from installing/working to a "gold" level according to winehq definitions are (i) winhelp and (ii) either MFC42 implementation (required for WSH to install properly; I suppose only a few functions prob are really required, but I'm not sure how good an idea having a very small stub MFC42 would be) or JScript support in wine. Either item in (ii) seems like a very significant undertaking, but (i) seems doable and prob. necessary for a lot of apps. So anyhow just my attempt to influence someone to start working on winhelp. Sorry for cluttering your inboxes. Misha
Btw I should have posted the URL to the demo version:
http://download.invitrogen.com/evergreen/Vector%20NTI%20Advance%2010.exe
To me the main problem with winhelp here is just that none of the winhelp navigation (Contents, Search, etc.) is implemented, making it difficult to, for example, answer the question "how do I do X?" which I'm sure Invitrogen would care about. From what I understand looking over some of the winhelp bug reports, the way .hlp files are currently processed this would be difficult/slow to implement, so probably a different way of processing them is necessary (don't know more than I read from searching for winhelp in the bugzilla for this tho, haven't investigated it myself).
Currently there is also a "bug" where WinHelp returns the incorrect value (WM_SENDDATA in winhelp program returns 0L and thus so does WinHelp which just returns the result of SendMessage, whereas according to MSDN WinHelp() shoudl return non-zero on success). In any case this latter thing would be pretty easy to fix, but I think really the rest of winhelp would need to be fixed for this second part to have any real use (other than removing an annoying "Failed to open help file" dialog).
Thanks everybody Misha
