  • Java - ClassNotFoundException I have the class included, but why do I get an exception?

    - by aloh
    public static Reservation[] openBinaryFile( String fileName ) { Reservation [] objArray = null; try { ObjectInputStream inStream = new ObjectInputStream( new FileInputStream( fileName ) ); objArray = (Reservation[])inStream.readObject(); inStream.close(); } catch( ClassNotFoundException e ) { System.out.println( "Exception: ClassNotFoundException." ); } I have the class included, but why do I get an exception? The class is in the same package as the others. Why am I getting this exception?

  • HttpModule to Write Out JavaScript Script References to the Response

    - by Chris
    On my page in the Page_Load event I add a collection of strings to the Context object. I have an HttpModule that will fire EndRequest and retrieve the collection of strings. What I then do is write out a script reference tag (based on the collection of strings) to the response. The problem is that the page reads the script reference but doesn't retrieve the contents of the file (I imagine because this is occurring in the EndRequest event). I can't fire the BeginRequest event because I won't have access to the Context Items collection. I tried to also registering an HttpHandler which Processes the request of the script reference but I can't access the collection of strings in the Context.Items from there. Any suggestions? Page_Load: protected void Page_Load(object sender, EventArgs e) { Context.Items.Add("ScriptFile", "/UserControls.js"); } HttpModule: public void OnEndRequest(Object s, EventArgs e) { HttpApplication app = s as HttpApplication; object script = app.Context.Items["ScriptFile"]; app.Response.Write("<script type='text/javascript' src='" + script + "'></script>"); }

  • Hotkey for double-click highlight?

    - by Steven Wright
    I'm working in Eclipse and find myself always replacing multiple copies of the same word, but I always have to take my hands off the keyboard and screen to get the mouse, hover over the word, double click to select, and then copy or rewrite the word. Is there any way I can just move the cursor inside the word and hit some hotkey that would highlight it? Seems like this would be a big timesaver. Or if there's a way to create a hotkey that would be perfect too.

  • Handwritten linked list is segfaulting and I don't understand why

    - by Born2Smile
    Hi I was working on a bit of fun, making an interface to run gnuplot from within c++, and for some reason the my linked list implementation fails. The code below fails on the line plots-append(&plot). Stepping through the code I discovered that for some reason the destructor ~John() is called immediately after the constructor John(), and I cannot seem to figure out why. The code included below is a stripped down version operating only on Plot*. Originally I made the linked list as a template class. And it worked fine as ll<int and ll<char* but for some reason it fails as ll<Plot*. Could youp please help me figure out why it fails? and perhaps help me understand how to make it work? In advance: Thanks a heap! //B2S #include <string.h class Plot{ char title[80]; public: Plot(){ } }; class Link{ Plot* element; Link* next; Link* prev; friend class ll; }; class ll{ Link* head; Link* tail; public: ll(){ head = tail = new Link(); head-prev = tail-prev = head-next = tail-next = head; } ~ll(){ while (head!=tail){ tail = tail-prev; delete tail-next; } delete head; } void append(Plot* element){ tail-element = element; tail-next = new Link(); tail-next-prev = tail; tail-next = tail; } }; class John{ ll* plots; public: John(){ plots= new ll(); } ~John(){ delete plots; } John(Plot* plot){ John(); plots-append(plot); } }; int main(){ Plot p; John k(&p); }

  • How can I install the BlackBerry v5.0.0 component pack into Eclipse?

    - by Dan J
    I'm trying to install the latest v5.0.0 "beta 2" BlackBerry OS Component Pack into Eclipse 3.4.2 with BlackBerry Eclipse plugin v1.0.0.67, but have hit a few problems. Has anybody found an easy way to do this? I had no trouble installing the v4.5.0 and v4.7.0 Component Packs. It's rather strange that BlackBerry are shipping new phones with the v5.0.0 OS installed (e.g. a Storm 2 9550 and Bold 9700 that I just bought), and pushing that update to phones whilst the BlackBerry website still considers the v5.0.0 SDK / Component Packs to be "beta 2"! If anybody knows when an official non-beta Component Pack is going to be released that might solve my problem... In case it helps, the problems I've hit so far are: -Contrary to the implication on the BlackBerry website, the Eclipse "Software Update..." option for the v5.0.0 Component Pack claims it only works on the v1.0.0 Eclipse BlackBerry plugin, not the new v1.1 one. -I then tried to install the v5.0.0 Component Pack through the "Software Updates..." menu in Eclipse using the v1.0.0 Eclipse BlackBery plugin. Once I'd done the 200MB download the install failed with a "Invalid zip file format" error. -I might just have been unlucky with a corrupted download but I did try it twice, once through "Software Updates..." and once by selecting "Archive" to install the downloaded Component Pack (which unlike v4.5.0 and v4.7.0 was a JAR, not a ZIP).

  • find: What's up with basename and dirname?

    - by temp2290
    I'm using find for a task and I noticed that when I do something like this: find `pwd` -name "file.ext" -exec echo $(dirname {}) \; it will give you dots only for each match. When you s/dirname/basename in that command you get the full pathnames. Am I screwing something up here or is this expected behavior? I'm used to basename giving you the name of the file (in this case "file.ext") and dirname giving you the rest of the path.

  • Where do I put all these function-like #defines, in C?

    - by Tristan
    I'm working with an embedded system, and I'm ending up with a ton of HW-interfacing #define functions. I want to put all of these into a separate file (for OOP-ness), but I don't know the best way to #include that. Do I just put them all into a .c file, then include that? Seems silly to put these in a .h file.

  • Detecting EOF in a Binary File using Scheme

  • handling mouseover/mouseout events for dijit.TitlePane's titleNode

    - by Shailesh Kumar
    I have a lot of dijit.TitlePanes stacked up one after another. I wish to handle the onmouseover and onmouseout events for the tile part of the TitlePane. What is the correct way of doing this? Will something like : dojo.connect(titlePane.titleNode, 'onmouseover', function f() {}); work, where titlePane is a reference to some dijit.TitlePane object? Is there some declarative way of setting up such an event handler using "dojo/mehtod"?

  • using paperclip with secure and non-secure files

    - by crankharder
    First off, we have this namespaced/sti'd structure for our different types of 'Media' Media< Ar::Base Media::Local < Media Media::Local::Image < Media::Local Media::Local::Csv < Media::Local etc... etc.. This is excellent since a user can have many media, and how we display each piece of media is based on the class name and a co-responding partial. But what if we have some Csv's that need to be secure? That is, they can't reside inside of public. I really hate the idea of branching Media again and doing something like this: Media::Secure < Media Media::Secure::Image < Media::Secure Media::NotSecure < Media Media::NotSecure::Image < Media::NotSecure ...where Secure and NotSecure would have different params passed to has_attached_file. Now there are two classes that represent Image and it makes my view/helper system that much more complicated -- not to mention it feels very obtuse. What I would really like to do is be able to change where certain Paperclip::Attachment objects get saved before they get saved (e.g. anything uploaded through foo_secure_action) -- but I can't seem to make this work. Paperclip::Attachment has an @options hash with :path and :url, but changing those before it is saved doesn't have an effect on where it actually gets set. Even if this is possible, I'm not sure if it would have further consequences... I'm open to alternative ideas for structuring this data, but for the moment I like the idea of using STI for this situation.

  • Recieveing "EXC_BAD_ACCESS" before any UI elements load (on device only)

    - by morgancodes
    Everything works fine on the simulator, but I gete EXC_BAD_ACCESS when I try to load my app on the device. I've put in a bunch of NSLogs to try and catch where it happens, but the log statements are never reached. Also, the UI doesn't load. So, seems the problem is happening before any of my code is reached. I tried a clean build, no luck. Also tried building and installing a different app, which works fine. So, looks like there's something wrong with my app, but it's something that happens before any of my code gets called. So, any ideas?

    - by Tom
    Hi, I Want a php code to turn a youtube/dailymotion/vimeo/metacafe... URL into an EMBEDABLE code so i can show it using echo , it is really hard to read the API of every website, so i'm wondering if there is a class or code to do this.

  • How do I specify a keys password with MSBuild for the purpose of using Hudson?

    - by Brett Ryan
    We have just setup our hudson server to build .NET projects which seems to be working fine, however for projects that require a password when signing the assemblies I can not figure out how to tell hudson what the password is? For us the password is asked the first time a developer checks out the source code and they open with visual studio, how is this stored? Can we just place a secret file somewhere on the server?

  • Avoid cache overflow in Atempo LiveBackup

    - by Vebjorn Ljosa
    When attempting the initial backup of a new client, Atempo LiveBackup seems to require a very large cache. For instance, a 20 GB cache is not enough to back up a computer that has 100 GB of data. It appears that LiveBackup is adding new files to the cache at a faster rate than it can send them to the server. When the cache fills up, the backup fails. Aside from removing most data from the computer and then add them back gradually after the initial backup, is there a good workaround? Is it possible to make LiveBackup slow down its scan so as to not fill the cache? Or is it possible to place the cache on an external drive?

  • Postfix mail server: can't connect via POP/IMAP

    - by MelkerOVan
    I've followed this guide on setting up a mail server on my dedicated server. I've been able to send mails from the php application I'm using and the linux commandline (using telnet, php, etc). The problem is that I cannot connect to the server via IMAP/POP which I've setup using Courier. I've tried using thunderbird but it complains that the username or password is wrong. I doubt it is the username/password but I don't know how to trouble shoot this. Edit: Here's the messages in mail.log: Jan 9 22:43:38 mail authdaemond: received auth request, service=imap, authtype=login Jan 9 22:43:38 mail authdaemond: authmysql: trying this module Jan 9 22:43:38 mail authdaemond: SQL query: SELECT id, crypt, "", uid, gid, home, "", "", name, "" FROM users WHERE id = '[email protected]' AND (enabled=1) Jan 9 22:43:38 mail authdaemond: password matches successfully Jan 9 22:43:38 mail authdaemond: authmysql: sysusername=<null>, sysuserid=5000, sysgroupid=5000, homedir=/var/spool/mail/virtual, [email protected], fullname=peter, maildir=<null>, quota=<null>, options=<null> Jan 9 22:43:38 mail authdaemond: authmysql: clearpasswd=<null>, passwd=6SrBcYq65l8QU Jan 9 22:43:38 mail authdaemond: Authenticated: sysusername=<null>, sysuserid=5000, sysgroupid=5000, homedir=/var/spool/mail/virtual, [email protected], fullname=peter, maildir=<null>, quota=<null>, options=<null> Jan 9 22:43:38 mail authdaemond: Authenticated: clearpasswd=peter, passwd=6SrBcYq65l8QU Jan 9 22:43:38 mail imapd: chdir Maildir: No such file or directory

  • How do I disable startup dll and programs in vista?

    - by phoenixoflight
    Here is the situation. I can't get into Vista or boot into safe mode. I get blue screened either way during the loading process. I would like to try to disable as many dlls and programs from loading at boot as I can. What files in vista do I change to go about doing this? All the guides I've seen do it from within Vista. I have a BartPE bootable cd that I'm using to get into the file system. I just need to know which files to modify. Thanks much for reading

  • Visual Studio .NET 2003 on Windows 7 hangs on search

    - by Nikhil
    So I have Visual Studio 2003 running on Windows 7 - yeah I am aware it isn't officially supported - and no, unfortunately I can't change that situation :-( For the most part it works OK but I have a specific problem, that I can't figure out. The application hangs if you do a project wide search (Ctrl - Shift - F) for a string. I have a reasonably powerful machine and all the other heavy tasks like compiling and debugging all work fine. It also works if I restrict the search to the current document (Ctrl - F). I am running it as administrator and VS.NET 2003 SP1 has been applied. The size of the project does not seem to be a problem since a colleague is also experiencing this issue for a single project solution containing 5 pages. I am currently using Windows Search as a work-around and I was wondering if there is something I missed that I should try. PS: I have asked this question on stack overflow as well - but I suspect this might be problem with Windows 7 OS - so I thought I'd cross post it here as well.

  • Windows XP over two monitors, but one of them switches off at boot... how to fix? How to switch bac

    - by jae
    When booting into XP (x64, Athlon II X2 245, 4GB RAM), my main monitor (got two 19" TFTs hooked up, two gfx cards, a 4650 (1GB, the primary monitor's on this) and a 4350 (512MB)) switches off. Logging in blind (cursor down key, typing password) gets me one screen, the secondary. Booted correctly until about two days ago. No clue what's the cause, last change was (if I don't overlook something) installing the ATI 9-12 hotfix. And booting into Windows 7, after returning from 7, it was like this. For some weird reason, I cannot start Catalyst Control Center (I right-click desktop, choose the CCC entry, the pointer changes to hourglass for a half-second... and nothing. Likewise with "Properties"... I think, as all windows open on the primary (off) screen, and no entry appears in the task bar for Properties) Completely stumped. Windows 7, same setup, works w/o a hitch. The primary monitor appears to run in some unknown, but pretty low, resolution, as the mouse pointer only moves onto it at about half-height. But, w/o CCC or display properties, I cannot check. And, obviously, not change anything. Hope this was not too long-winded. And I'm sure I still forgot essential stuff. :P

    Thanks in advance for your help! As the title states, I have Windows 7 x64 Boot Camp Partition, Snow Leopard on MBP, and VMWare Fusion 2.x/3.x. I'm trying to open the partition as a vm and I get into an endless cycle where windows tries to Repair Start Up disk for a very long time before failing. The boot camp partition runs fine natively. Has anyone experienced this? Can someone provide or link a remedy? My google fu is failing miserably ....

  • C-array to NSData and back

    - by Thor Frølich
    I'm attempting to save a c-style array of Vertex3D structs to an NSData object and get them back when reloading the app: NSData *vert = [NSData dataWithBytes:&vertices length:(sizeof(Vertex3D) * NUM_OF_VERTICES)]; This data is then saved and attempted to be read back into my c-array thusly: vertices = malloc(sizeof(Vertex3D) * NUM_OF_VERTICES); [vert getBytes:&vertices length:(sizeof(Vertex3D) * NUM_OF_VERTICES)]; The above results in “EXC_BAD_ACCESS” followed by: malloc: * error for object 0x48423c0: pointer being freed was not allocated I'm very new to programming so there's probably some fundamental memory management principle I'm unaware of. I have verified that the loaded NSData is identical to the saved one, but it's clear that the transition from c-array to NSData (and back) is not as I intended.

  • Project. Properties.Settings versus plain old appSettings?

    - by BryanG
    I have an assembly built that uses appSettings in the app.config...pretty straight forward. however, I'm referencing this assembly in a web service, and that web service contains the nAnt build file for this service plus being the entry point for everything. Ideally I'd like to be able to set the assembly's appConfig values from the build file, but is this possible? Or do I have to switch to using the Settings values of the assembly and do something like this in the build: <xmlpoke file="${PublishLocation}\web.config" xpath="//applicationSettings/Namespace.AssemblyClass.Properties.Settings/setting[@name='ExchangeServer']/value" value="${ServerName}" /> You get the idea. Is this possible with just a config? My ideal situation would be to keep the settings more flexible in the appConfig so that when everything is on the server, if frogs rain down, I can update the assembly's config values without rebuilding the solution. Is this even possible (the xpath is wrong, it's just an example of what I'd like to do): <xmlpoke file="${PublishLocation}\web.config" xpath="//appSettings/Namespace/AssemblyClass/add[@key = 'ExchangeServer']/@value" value="${a}" />
