<0> jottinger the search engine is C++ and some very old (about to be upgraded) C
<1> vawjrwrk: do you know anything about bigpharmanews.co.uk?
<2> not in the package - i already had them from years ago
<0> jottinger not yet
<1> vawjrwrk: *nod*
<3> ok lots of free sat out there...like red hot 'n' duthch :)
<1> it's a news site for pharms, as you might judge
<2> nah, the porn on their is crap :-)
<4> As far as UI goes I think people use .NET more than MFC now.
<0> jottinger they don't have a website using that name
<1> vawjrwrk: hmm, I wonder what happened to it
<2> dwork, yes as far as advertised jobs go, .net/forms are the most popular thing
<0> I tried what you posted and www.
<1> hmm, he might have shut it down
<1> yeah, I see
<1> I used to host it for the guy who ran it
<1> he moved it off and apparently shut it down
<5> sounds remarkably like a spam site
<2> hmm, have MS ***igned a special meaning to ^ when using C++ with .net?
<5> In C++/CLI, yes
<5> ^ is a gc reference
<5> i.e. a reference to a type on the managed heap
<5> I think they call then "handles"
<2> hmm, i think i'm going to install VC8 to play with this stuff
<5> just to overload that term *even more*, which is surely needs
<5> good idea. Come visit us in #c++/cli if you want more info :0
<5> :)
<3> the c++/cli is a huge improvement over mc++
<2> I never got round to playing with mc++ either
<3> an abomination it was
<6> greetings
<0> howdies
<6> how you doing?
<0> well, it looks like i forgot to put some stuff in cvs, so a little distracted
<6> ;)
<6> could i maybe have a few minutes with you, when you arent?
<0> read the topic
<6> oh right, sorry.
<6> could i pm you tho/
<6> ?
<3> wtf do you want?
<6> who's talking to you?
<3> see topic or go away
<0> Guest67184 this is a public help channel, it's presumed that if you have a problem that you'll want as many eyes on it as possible
<3> i guess he just wants to have babies with you...
<0> not gonna happen
<3> its a miracle
<6> atleast i wasnt being a ****head...i asked nicely, didnt i? your tone isnt appreciated, bealtine
<2> Guest67184, had you "just asked" there wouldn't have been a problem
<0> your tone isn't appreaciated either
<0> "who's talking to you" isn't exactly polite
<0> so you gonna ask something? or post something??
<6> and 'wtf do you want' is?
<0> doesn't matter
<0> are you gonna get to the ****ing point
<3> moron
<7> ****ing hurricane out again
<7> stupid wind god
<7> makes a horrendous noise that i can hear in the master bedroom as the wind p***es through the external exhaust vent of the gas fireplace in the room below
<7> has to be gusting 40-50 mph out
<3> we had a little beatie last night too...
<1> peterhu: where are you, geographically?
<7> leesburg, virginia
<7> who slashdotted slashdot
<8> guys, what's the best way to search for a string in a binary ifstream?
<9> >_>
<8> >>?
<10> Define 'best'
<8> faster
<8> I need the position of some string
<10> Is the string you look for also binary? Or is it ascii?
<8> binary
<10> Is there anything known about the frequency of occuring values?
<8> yes, once
<10> of characters I meant.
<8> the whole string apears only once in the whole file
<10> If you know nothing special about the data, then there is no trick.
<10> just read the file and search for the first character :/, if you find it, check the next character etc.
<0> boyer-moore might give you a faster search
<8> boyer-moore?
<0> do a search
<8> ok, thanks
<2> sk8ing: http://en.wikipedia.org/wiki/Boyer-Moore_string_search_algorithm
<8> to both of you
<10> But if for example you look for a long ascii string in a random file, then I'd skip bytes. Say the length is 16 chars, then I'd just check every 16 bytes and only really start to look when I find two ascii values (then look between them too).
<8> Run, this is a better solution... but the string is not that long unfortunatly...
<8> I'll go with the slower algo
<0> sk8ing the longer the string, the faster boyer-moor is
<0> err, boyer-moore
<0> how long is the "string" ?
<8> 6 chars
<8> with the ending 0... 7
<10> ending 0??
<10> You said it was binary!
<8> it has an ending 0
<10> normally only printable text ends in a 0
<8> I know
<10> if it's binary there can be a 0 anywhere, so what use is the terminating 0?
<8> I haven't sleep in 30-40 hours a bit.. it's a 7 chars string with an endig 0
<8> *ending
<10> Anyway... your main problem is reading the data imho, not searching it.
<10> yeah, and next you tell me it's aligned too.
<8> do you think I can't read a fstream? come on...
<8> I have to search 9999 files for this string
<8> and modify it
<8> that's the problem
<0> getting some sleep sounds like a good idea
<8> lol
<8> I know
<8> :)
<0> overall it's likely to take you less time
<10> If you really need it video-driver-fast, then you should get the streambuf pointers and use an ***embly instruction to look for the 0 byte, and then test if the string is there. special cases for when that wraps a buffer boundary. Lots and lots of work.
<10> But you don't need that speed. Just read the file char by char, test the first char etc.
<8> I'll do it this way for now, thanks
<11> I am having problems with an Embest JTAG Flash Programming software for my chipset, do you have experience with this?
<0> I've only used the AVR programming stuff
<10> vawjrwrk: you know spirit a bit? How can I match a RULE zero or one time?
<10> zero or more times would be: *RULE
<0> yeah, the kleene star goes at the beginning
<0> it might need *(RULE) but I don't recall for sure
<10> (RULE | nothing_p) ?
<0> sorry
<0> missed the 0 or 1
<0> I thought they had a special thing for that since it's so common
<0> called "optional" iirc
<10> docs have no idex :(
<2> well it should be ?, but I don't think that can work :-)
<10> Ah, found it.
<10> !RULE
<0> http://www.boost.org/libs/spirit/doc/operators.html
<0> yeah, you found it
<0> peterhu do you know of a way to "add" some search paths (for includes) for a single solution?
<10> I now have this: http://www.rafb.net/paste/results/6zPC3037.html
<7> create a project property sheet in the property manager, set the property on it, right click on the solution node and select "add existing property sheet", select the created property sheet
<7> should affect all c++ projects
<10> I hope that is correct... it would help to have real parsing rules for C++ :)
<0> I was lucky when I had a project to use Spirit.. I managed to find an EBNF description of the language (Matlab)
<12> is there a way i can change the word length or create my own integer data type to be 256 bytes or anything like that?
<0> mltngpot write your own cl***
<7> (btw, you create a new property sheet on a particular project first, store the property sheet in a common path, and then ***ociate the solution with the property sheet)
<0> peterhu where's the property manager?
<12> vaw: so i basically need to write a whole new math library then?
<7> note that as you add new projects, you'll have to ***ociate them with the property sheet
<7> View -> Property Manager
<7> oh wait, i forgot, there is no solution node
<7> you multi-select all the projects
<7> sorry
<0> ok, thanks
<7> to edit the property sheet, double click it's node in the property manager
<0> doesn't MS _ever_ think in terms of hierarchical files?
