Direct access to LPT1
by E Lea 24 Jul '03

24 Jul '03

I'm playing around with a program that controls a small "design cutter" - it's basically a plotter that connects via the parallel port. There is some Windows CAD software that knows about the plotter and sends commands to it, as far as I can tell in one of two ways: 1) Through a printer driver. It doesn't seem too bothered about the details of the driver though. I'm assuming that one would normally use a generic, text-only Windows driver. This method, apparently, has the advantage of the driver buffering the output 2) The second method is a direct connection to LPT1. With Wine, in the first case I get a message in a dialog box saying the call to "StartDocPrinter" failed and fixme:winspool:StartDocPrinterA (hPrinter=0x1, Level=0x1, pDocInfo=0x408a28dc): stub to stdout. In the second case I get a dialog saying "LPT1 was not found" and fixme:dosfs:DOSFS_OpenDevice device open L"LPT1" not supported (yet) err:file:CreateFileW Couldn't open device L"LPT1"! to stdout. Is this a config issue? I'm assuming that is should be easier for me to get the second method working.

Re: Status_Wine #2 -- lostwages

I also would help, except I'm so short on time I know I wouldn't actually do anything, so I won't volunteer... I've been lurking around these lists for about 4 or so years now, so I've got a bit of an idea about some of the stuff that's happened. Maybe in the future I'll lend a hand. If I recall correctly, the 'history of wine' has come up a few times, so there may already be some material that could be used. Here are a couple of short threads about it from last year: http://www.winehq.com/hypermail/wine-devel/2002/11/0910.html http://www.winehq.com/hypermail/wine-devel/2002/11/0378.html Some of the people who have had a dab at the history of wine are still active on this list and may have some material. Anyway, didn't Alexandre give a presentation on the history of wine at Wineconf 2002? Certainly according to this page he did: http://kt.zork.net/wine/wn20020325_118.html I don't know how extensive the presentation was, but if there are records of it, it may be a good starting point. Don't know if this helps at all, Probably everyone knew all this anyway ;) Joel Carr -- __________________________________________________________ Sign-up for your own FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup CareerBuilder.com has over 400,000 jobs.

typelib caching
by Mike Hearn 24 Jul '03

24 Jul '03

Well, it works, finally. No more crashes/hangs :) That is - sort of. Unfortunately, it's a bit too slow to be usable. A few wild stabs in the dark and some timing traces showed the culprit to be LoadTypeLibEx: trace:ole:LoadTypeLibEx File L"C:\\windows\\system\\SHDOCVW.DLL" index 1 trace:ole:LoadTypeLibEx returns 00000000, in 15 milliseconds trace:ole:LoadTypeLibEx File L"C:\\windows\\system\\SHDOCVW.DLL" index 1 (hmmmm, we load it again?) trace:ole:LoadTypeLibEx returns 00000000, in 46 milliseconds (odd, slower than last time) trace:ole:LoadTypeLibEx File L"C:\\windows\\system\\mshtml.tlb" index 1 trace:ole:LoadTypeLibEx returns 00000000, in 1208 milliseconds (over a second parsing the type library? well, maybe it is quite large) trace:ole:LoadTypeLibEx File L"C:\\windows\\system\\mshtml.tlb" index 1 trace:ole:LoadTypeLibEx returns 00000000, in 6689 milliseconds (almost 7 seconds to parse the type lib a second time!?!) trace:ole:LoadTypeLibEx File L"C:\\windows\\system\\mshtml.tlb" index 1 trace:ole:LoadTypeLibEx returns 00000000, in 42139 milliseconds Waaaaaaah, 42 seconds! There's a big source of the sluggishness. So, a few questions that I can chew on tomorrow: * Shouldn't typelib loading be cached somewhere? Reparsing typelibs like this seems rather wasteful. * Why on earth would the time taken go up so massively on each run? * Where abouts in the typelib parsing could the speed hit be? Pretty clearly no typelib is going to be so complex it takes an Athlon 1200 almost a minute to parse, there is a nasty bug there somewhere. thanks -mike

Not exactly equivalent here. The ptr type is not 0x12 here, I think; supplying NULL here is completely invalid and the MIDL code in oaidl_p.c will raise an exception, completely refusing to marshal the call at all. If supplying NULL is supposed to be valid at the API level, it must be handled by the IDispatch_Invoke_Proxy wrapper in usrmarshal.c, converting the NULL to IID_NULL, before passing it off to the MIDL-generated marshaller. (This Invoke wrapper already treats some other can-be-NULL arguments in this manner, so this would just be yet another case of this.) > > You probably just need to marshal an extra flag saying > > whether the pointer is null or not, but since I haven't seen the DCE RPC > > spec I don't know what the flag should look like. > > Is that just a case of adding another IStream::Write call, and having > the equivalent read in the custom demarshaller?

is there a "wine coding guide" available?
by Jonathan Wilson 24 Jul '03

24 Jul '03

Something that covers things like coding style, things not to do in wine (e.g. because they arent portable enough) and so on.
