  • Saving MP3 playlist to file

    - by Northernen
    Hello. I am making my own crude MP3 player, and I now have a JList with which I have populated a number of files in the form of MP3 objects (displayed on frame using DefaultListModel). I would now like to have the oppurtunity to save this JList to a file on disk. How would I go about doing this? I'm very new with programming and Java, so help is greatly appreciated.

  • What's your favorite cross domain cookie sharing approach?

    - by Haoest
    I see iframe/p3p trick is the most popular one around, but I personally don't like it because javascript + hidden fields + frame really make it look like a hack job. I've also come across a master-slave approach using web service to communicate (http://www.15seconds.com/issue/971108.htm) and it seems better because it's transparent to the user and it's robust against different browsers. Is there any better approaches, and what are the pros and cons of each?

    - by pssguy
    I have a dataframe which has merged player and team data for soccer seasons So for a particular player in a specific season I have data like df <- data.frame(team=c(NA,"CRP",NA,"CRP","CRP",NA), player=c(NA,"Ed",NA,"Ed","Ed",NA), playerGame= c(NA,1,NA,2,3,NA), teamGame =c(1,2,3,4,5,6)) Where the NA's indicate that the player did not appear in that specific team game How would I most efficiently replace the team and player NA's with "CRP" and "Ed" respectively and have a plGame output of, in this instance, 0,1,1,2,3,3

  • Good JavaScript engine for animating via Sprite Sheets (not in canvas)

    - by N. Taylor Mullen
    I've looked around a bit for a great JavaScript Sprite Sheet animator lib/engine but couldn't find any good ones so I thought I'd ask around =). What I'm looking for in the engine is: Animate an image in a non-canvas setting (ex: div via css or img tags) Control frame rate/animation speed Flags to loop or to animate once etc. Are there any engines like this out there? If not I can always make my own but then again, I don't want to re-invent the wheel =].

  • Java- screen capture behind the application.

    - by Auxiliary
    Is there a way to capture the screen but without the app itself getting shown. I know how to minimize or make a frame invisible but this has to be done real fast cos it's going to happen alot in each second (at least once every second). I want it to look something like the magnifier in Windows Vista/7. (The app can see behind itself.) Thanks in advance.

  • How to resize html canvas element?

    - by russx2
    I have a canvas element defined statically in the html with a width and height. If I attempt to use JavaScript to resize it dynamically (setting a new width and height - either on the attributes of the canvas or via the style properties) I get the following error in Firefox: uncaught exception: [Exception... "Illegal operation on WrappedNative prototype object" nsresult: "0x8057000c (NS_ERROR_XPC_BAD_OP_ON_WN_PROTO)" location: "JS frame :: file:///home/russh/Desktop/test.html :: onclick :: line 1" data: no] Is it possible to resize this element or do I have to destroy it and create a new element on the fly?

  • bounce multiple servers using ant

    - by Angrezy
    Hi All, This is restart target code which is defined in build.xml target name="restart" propertycopy name="remote.host" from="deploy.${target.env}.host.${remote.id}" propertycopy name="remote.port" from="deploy.${target.env}.port.${remote.id}" sshexec trust="true" host="${remote.host}" port="${remote.port}" username="${scm.user}" keyfile="${scm.user.key}" command="sudo /usr/local/bin/bounce_jboss" target server information is defined in build.properties. The above code is working fine, but the restarting process is very late bcas its stopping-starting server one and later its stopping-starting another server, Is there a way where i can restart both servers parallely with a time frame of 45 seconds.

  • IronPython memory leak?

    - by Mike Gates
    Run this: for i in range(1000000000): a = [] It looks like the list objects being created never get marked for garbage collection. From a memory profiler, it looks like the interpreter's stack frame is holding onto all the list objects, so GC can never do anything about it. Is this by design?

  • Quaternion Cameras and projectile vectors

    - by Tom J Nowell
    In our software we have a camera based on mouse movement, and a quarternion at its heart. We want to fire projectiles from this position, which we can do, however we want to use the camera to aim. The projectile takes a vector which it will add to its position each game frame. How do we acquire such a vector from a given camera/quaternion?

    - by Vaccano
    I really want to upgrade to Visual Studio 2010. But since I do a lot of development for the Pocket PC version of Windows Mobile I cannot. (I develop for a Symbol device that does not support Windows Phone 7, so that is not a option.) Does any one know any kind of time frame of when Microsoft plans to add support for Smart Device Projects into Visual Studio 2010
