<0> anybody knows how to print in Java?
<1> ma ningun culero te contesta xD
<2> doc` : lots of stuff out there
<2> you can use Swing , and print it using the Swing stuff
<0> i got a problem
<2> you can print to a pdf document , and maybe then print it
<1> que te dice ese chavo? :|
<0> my program only prints one time, when i send to print again i get a Exception, when i restart the computer i can print again one time =/
<0>
<3> i want to insert a file into a db, so i need to open a file as simple bytes to p*** it to the insert funciont. Whitch cl*** do i need to work with the file?
<3> anyone_
<3> ?
<4> You read the file in with streams. (FileInputStream for example).
<4> Likewise, you'll use streams to push the data to the database (for blob fields etc).
<1> :|
<1> nadie te ayudo .:S
<4> WTF
<3> Talden: thx
<3> Talden: i've no experience with uploading files to a db, so i just p*** the stream as a blob type? (i'm working with oracle)
<5> does java really **** at GUI's?
<2> heh
<2> what kind ?
<2> 3D games ?
<5> what do u mean what kind?
<5> nope
<2> business ?
<5> somewhat like that
<2> you know, like... excel
<6> define "****" even.
<5> with buttons, listbox, editbox, etc
<2> well, Swing can be a bit troublesome to learn.
<2> but it works.
<6> and with some gui builders there's not much to learn
<2> With netbeans matisse , you can build it in minutes
<5> netbeans matisse?
<2> part of the netbeans IDE
<6> "Netbeans Swing GUI builder" aka "Project Matisse".
<5> can you do GUI designs with ease using that?
<2> those input forms, buttons, whatnot , yes
<2> If you want a 3d table , superflexible, DnD inter-application...
<2> That might pull some hair out
<6> try and find out I'd say. When done right you should even be able to do this easily in a text-based editor IMO.
<2> there are also GUIs made in XML
<6> aye
<5> can you enumerate the widgets that is able to be created using java?
<3> maybe this is more DB than Java, anyway: at the INSERT statement how do i inset the blob field with the FileInputStream instance?
<5> nevermind.. found the demo
<7> dudes, I used getfields to get for example BufferedImage.TYPE_INT_RGB from BufferedImage constructor using reflection but it only returns int ... how can I get constants ?
<7> I get that BufferedImage(int , int, int) , how can I know that the last int is imagetype and can take specific values.. e.g. TYPE_INT_RGB
<7> does this make more sense ?
<6> sounds to me that you should check the API docs.
<6> apart from that I have no idea. Not without checking those myself that is :P
<7> did checks the docs.. did do what they say.. and still cannot figure out how to get the fact they are constants
<7> I can get the modifiers and see they are static for example , but that wont help
<6> int and constants aren't really comparible.
<6> an int can very well be a constant. Then again; Java doesn't grok constants, it does grok final though.
<7> hm..
<6> and static also has nothing to do with all this. So in the overal, at least to me, you're not making any sense what so ever.
<7> hehehehee
<7> lol
<7> ok,Ill try to rephrase my thought : java.awt.image.BufferedImage(int,int,int) accepts 3 ints, BUT the constractor wonts int to have one of predefined values to work.. how do I get these predefined values , e.g TYPE_BYTE_INDEXED, TYPE_USHORT_565_RGB, TYPE_USHORT_555_RGB
<6> check the API docs.
<7> TYPE_3BYTE_BGR for example is int 5
<7> I want to get the possible values through reflection... thats my issue, I know the possible values but I want to retrieve them for any given cl*** during runtime
<8> Hello
<8> Why do exceptions in Java not have an error code? Is there a design decision behind this? What is the best way to recognise an exception if it checking what type it is is not enough?
<8> say, "SQLException: could not connect" from "SQLException: could not insert, duplicate primary key not allowed, violation of constraint"
<9> use a finer grained try/catch block comes to come. doing text comparision as a last resort (potentially prone to problems).
<1> anybody knows how to print in Java?
<10> is there something apart of the java language that will make certain lines of code only execute durring debugging?
<11> where is X
<0> vacations.
<12> morning
<13> morning
<12> hey wlfshmn, wh***up?
<13> not much, sitting at home waiting for someone fomr the contractor to show up and replace my lock
<13> or rather, reinstall my lock instead of theirs
<13> this is a good thing, because it means I can no longer be supprised by constructionworkers at 7am inside my appartment
<12> someone actually entered your appartment?!
<13> They have been renovating the pipes in the complex and renovating the bathrooms
<13> so there has been a valid reason for them to be in here. I do prefere to have mkore controll over who comes and leaves though ;)
<12> :)
<12> well, bbl, gotta go walk the dog and the get my hair cut
<12> then
<10> is there something apart of the java language that will make certain lines of code only execute durring debugging?
<13> No
<13> The codepath is the same for runtime and debuging. If it wasn't the debugger would be far less usefull than it currently is.
<10> or somthing akin to the C preprocessor
<13> You could look into ***ertions
<13> Not quite what you look for (it's no #ifdef), but it could be helpfull
<13> if the code you are trying to hide fomr runtime is debug output, you might want to use regular logging instead. Typically there is a debug loglevel
<10> ***ert is pretty good but they would still be compiled in a release
<10> ahh, good idea
<10> i would help if the debugging code was not in the erlease though
<13> debug loglevels are also there in release, and availible if you configure the log to be verbose enoguh though
<13> danimal_: I don't think there is a way to do that directly. You could apply your logic through AOP I suppose, but it might be more work than you want to put into it
<10> AOP?
<13> aspect oriented programming
<13> typically a manner of wrapping objects in dynamic proxies that contain specific functionality
<13> http://en.wikipedia.org/wiki/Aspect-oriented_programming
<10> yeah
<10> that's quite an article for this time of day
<13> yeah. I also think it's more work than you will want to put into this, and it still not a sure fit ;)
<14> morning
<13> morning
<12> danimal_ - what exactly are you trying to accomplish?
<10> essentially optional inclusion of certian lines of code in compilation
<10> roughly the similar features as the C preprocessor's #define #ifdef #ifndef #else #endif
<12> i guess you can use java preprocessor for that
<12> wlfshmn - ever played with AOP?
<13> MbGone: not for custom proxies, no
<13> so only in a psring context
<13> s/psring/spring/
<12> same here, but not with spring, with jboss makes life alot easier :)
<11> what's jboss?
<12> its an opensource application server http://www.jboss.org
<15> final static boolean debug = true; ... if (debug) ...
<15> ?
<15> moin
<12> morning Clackwell
<15> hi mb
<12> Clackwell - from what i gathered he didnt want to compile the code in the release version
<15> MbGone: he didn't want the debug code in the release build, right? the above might achieve that, if i recall correctly.
<12> as far as i know, this code will still b<16> Ew, javafaq.mine.nu _requires_ javascript to navigate. Ugly!
<15> really? tststs...
<15> see you later, eating and working...
<16> Clackwell: the left-nav doesn't work without it. Ick! Should be nested UL with css for mouseover, and href+target to load the page. Nothing fancy!
<16> see ya
<15> LLyric: it's certainly old school. rob made it a few years ago afterall. :)
<13> meh, my brilliant project manager that puts their only preexisting java resource (me) on .net development, has no determined that i am to be placed as first runner up to recieve .net training, in case somsone else gets sick...
<12> heh
<12> and what happens if you get the flu?
<17> hi
<12> hi
<13> if I get the flue, nothing happens, if someone else gets the flue, I might get to take a .net course..
<17> i'm looking for some help
<12> but didnt you say that you are the only jave resource?
<12> Goro|Mails_a - asking a question may help
<13> yes. the rest of the people (well, most of them) got an intro course to java a while back
<12> ahhh
<17> For sure ^^
<13> they code without much understanding ;)
<12> hehe
<17> i've a little problem in java, i'm trying to refresh a Jpanel...with no succes...
<17> i've create a cl*** which extends Canvas, then a add it in my jpanel
<17> in theory, this cl*** must handle with the drawing of of tree... its working when i started with a real tree (with values in)
<17> but when i start with an empty tree ( so the object is null), after that it refuse to refresh my japnel
