  • Line End Problem Reading with Scanner Class in Java

    - by dikbas
    I am not an experienced Java programmer and i'm trying to write some text to a file and then read it with Scanner. I know there are lots of ways of doing this, but i want to write records to file with delimiters, then read the pieces. The problem is so small. When I look the output some printing isn't seen(shown in below). I mean the bold line in the Output that is only written "Scanner". I would be appreciated if anyone can answer why "String: " isn't seen there. (Please answer just what i ask) I couldn't understand if it is a simple printing problem or a line end problem with "\r\n". Here is the code and output: import java.io.FileReader; import java.io.FileWriter; import java.io.IOException; import java.util.Scanner; public class Tmp { public static void main(String args[]) throws IOException { int i; boolean b; String str; FileWriter fout = new FileWriter("test.txt"); fout.write("Testing|10|true|two|false\r\n"); fout.write("Scanner|12|one|true|"); fout.close(); FileReader fin = new FileReader("Test.txt"); Scanner src = new Scanner(fin).useDelimiter("[|\\*]"); while (src.hasNext()) { if (src.hasNextInt()) { i = src.nextInt(); System.out.println("int: " + i); } else if (src.hasNextBoolean()) { b = src.nextBoolean(); System.out.println("boolean: " + b); } else { str = src.next(); System.out.println("String: " + str); } } fin.close(); } } Here is the output: String: Testing int: 10 boolean: true String: two String: false Scanner int: 12 String: one boolean: true

  • Several devices in Device Manager have Code 3 error

    - by John Straka
    One of our users' machines (Dell Optiplex 380 running Windows 7 32-bit) is having a weird driver issue. A bunch of devices have Error Code 3: The driver for this device might be corrupted, or your system may be running low on memory or other resources. (Code 3) The system isn't low on memory (only 1GB in use out of whatever the max for 32-bit is.) Here's a screenshot of the affected devices: I tried reinstalling the chipset and audio drivers to no avail. I have no idea what prompted it, and I'm not sure how the basic Windows Generic PnP Monitor driver could even be corrupted. What might be causing this error?

  • Deleting elements from stl set while iterating through it does not invalidate the iterators.

    - by pedromanoel
    I need to go through a set and remove elements that meet a predefined criteria. This is the test code I wrote: #include <set> #include <algorithm> void printElement(int value) { std::cout << value << " "; } int main() { int initNum[] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }; std::set<int> numbers(initNum, initNum + 10); // print '0 1 2 3 4 5 6 7 8 9' std::for_each(numbers.begin(), numbers.end(), printElement); std::set<int>::iterator it = numbers.begin(); // iterate through the set and erase all even numbers for (; it != numbers.end(); ++it) { int n = *it; if (n % 2 == 0) { // wouldn't invalidate the iterator? numbers.erase(it); } } // print '1 3 5 7 9' std::for_each(numbers.begin(), numbers.end(), printElement); return 0; } At first, I thought that erasing an element from the set while iterating through it would invalidate the iterator, and the increment at the for loop would have undefined behavior. Even though, I executed this test code and all went well, and I can't explain why. My question: Is this the defined behavior for std sets or is this implementation specific? I am using gcc 4.3.3 on ubuntu 10.04 (32-bit version), by the way. Thanks!

  • Which PSU should one chose? The biggest is the best?

    - by Shiki
    I'm fully aware of PSU's "Active PFC" and that they won't consume the written W all the time. (Makes sense). But now I'm before a PSU replacement (Guys: NEVER buy a Chieftec. Seriously.) The question is: If one can get a bigger one (in my case 750W and 650W) ... should that person go for the bigger one ? (The difference in price is not much). No, I don't think I'll soon use all that much. (Please help (if you want of course) to make the question more generic if the question is really not OK in this form. I've been wondering about this for a time already. In my case it would be XFX Black Edition Silver 750W and 650W) (Basically about "which one" I would go with XFX/Antec/something which comes with industry qualified parts. Like Duracell but in a PSU. :) But the performance is a different thing.)

  • Python list should be empty on class instance initialisation, but it's not. Why?

    - by canavanin
    Hi everyone! I would like to create instances of a class containing a list that's empty by default; instead of later setting this list to the final full list I would like to successively add items to it. Here's a piece of sample code illustrating this: #!/usr/bin/python class test: def __init__(self, lst=[], intg=0): self.lista = lst self.integer = intg name_dict = {} counter = 0 for name in ('Anne', 'Leo', 'Suzy'): counter += 1 name_dict[name] = test() name_dict[name].integer += 1 name_dict[name].lista.append(counter) print name, name_dict[name].integer, name_dict[name].lista When I ran the above program I expected to get Anne 1 [1] Leo 1 [2] Suzy 1 [3] as I assumed lista to always be initialised to an empty list. What I got instead was this: Anne 1 [1] Leo 1 [1, 2] Suzy 1 [1, 2, 3] If I replace self.lista = lst by self.lista = [] it works fine, just like when I add the line name_dict[name].lista = [] to the for loop. Why is it that the contents of the previous objects' lists are retained, yet their values of integer aren't? I am rather new to Python, so it would be great if someone could point out to me where my thoughts/assumptions have gone astray. Thanks a lot in advance for your replies.

  • Can't Redirect the root of my Domain

    - by JRameau
    My Issue: I can access:http://exampledomain.com/any/thing/I/want/2type But I can Not access:http://exampledomain.com or http://www.exampledomain.com -it gets redirected to the Default vhost, which is a generic construction page. I run on a plesk set-up: and originally "exampledomain" was its own Plesk Vhost domain. I run everything in drupal, so I want to just consolidate it onto a multisite, usually this is as simple as setting the correct folder structure in drupal, and just simply making the new domain an Alias of the bigger Vhost. I checked /etc/httpd/conf.d/zz010_psa_httpd.conf to see if there were any remnants of the old settings. Any suggestions, thanks in advance?

  • Images in IFRAME no longer showing after I log out of Flickr?

    - by contact-kram
    I have a iframe window which displays user's flickr images. I use the flickr.photos.search api to download the user's image from flickr. This works great when the user is logged into flickr. But when I explicitly log off the user from flickr and the yahoo network and then attempt to download the flickr images, I get redirected to www.yahoo.com in a full browser window (not in my iframe). If I remember correctly, I did not have this issue when I was not using iframes and I was being redirected to the yahoo login screen. Any suggestions? To elaborate, this URI - http://www.flickr.com/services/api/auth.howto.web.html, lists the below step - Create an auth handler When users follow your login url, they are directed to a page on flickr.com which asks them if they want to authorize your application. This page displays your application title and description along with the logo, if you uploaded one. When the user accepts the request, they are sent back to the Callback URL you defined in step 2. The URL will have a frob parameter added to it. For example, if your Callback URL was http://test.com/auth.php then the user might be redirected to http://test.com/auth.php?frob=185-837403740 (The frob value in this example is '185-837403740'). This does not happen when I am in my iframe window but it does happen in my full browser window.

  • pre_replace multi-dimensional array problem

    - by Martin
    I want to replace word groups by links. I use a multi-dimensional array to define these (in the real world there will be thousands of them). Here's the code: $text = "<html><body><pre> Here is Foo in text. Now come Baz? and Bar-X. Replace nothing here: Foo (followed by brackets). </pre></body></html>"; $s = array( array("t" => "Foo", "u" => "http://www.foo.com", "c" => "foo"), array("t" => "Baz?", "u" => "http://www.baz.net", "c" => "test"), array("t" => "Bar-X", "u" => "http://www.baz.org", "c" => "test") ); foreach ($s as $i => $row) { $replaced = preg_replace('/(?=\Q'.$row["t"].'\E[^(]+$)\b\Q'.$row["t"].'\E\b/m', '<a href="'.$row["u"].'" class="'.$row["c"].'">'.$row["t"].'</a>', $text); } echo $replaced; ?> The problem is that only one array element is replaced and not all. It's something about $text in peg_replace(). Anyone got a hint for me? Thanks!

  • What's the correct way to pass parameters from VBScript to COM interface implemented in C#?

    - by nopopem
    I'm trying to expose a fairly simple C# class to COM which should be usable from VBScript (among others). Some objects need to be created via COM calls and will be used in furter calls later on. The definition of the exposed classes and interfaces looks like this: namespace Test { [InterfaceType(ComInterfaceType.InterfaceIsIDispatch)] public interface IComInterface { IFoo CreateFoo(); void UseFoo(int x, IFoo f); } [ClassInterface(ClassInterfaceType.None)] public sealed class CComInterface : IComInterface { public CComInterface() {} public IFoo CreateFoo() { return new Foo(); } public void UseFoo(int x, IFoo f) { f.Bar(); } } [InterfaceType(ComInterfaceType.InterfaceIsIDispatch)] public interface IFoo { void Bar(); } [ClassInterface(ClassInterfaceType.None)] public class Foo : IFoo { internal Foo() {} public void Bar() {} } } The simplest thinkable COM client in VBScript does this: Dim ci Set ci = WScript.CreateObject("Test.CComInterface") Dim foo Set foo = ci.CreateFoo foo.Bar ci.UseFoo 0, foo While the call to Bar succeeds, calling UseFoo fails with "Error 5: invalid procedure call or invalid argument" The generated IDL seems ok to me: dispinterface IComInterface { properties: methods: [id(0x60020003)] IFoo* CreateFoo(); [id(0x60020004)] void UseFoo( [in] long x, [in] IFoo* f); }; The vbs call succeeds when I wrap the second parameter in parentheses like this: ci.UseFoo 0, (foo) As far as I understand (I'm no VBScript expert however) this forces the reference to foo to be passed by value, i.e. a copy of the reference is being made. How can I change the interface so that it can be called with the foo reference directly? Since this will be a public interface used by customers I don't like the idea of having to explain why all the objects created need to be passed back in an extra pair of parentheses...

  • Kohana Auth Library Deployment

    - by Steve
    My Kohana app runs perfectly on my local machine. When I deployed my app to a server (and adjust the config files appropriately), I can no longer log into the app. I've traced through the app login routine on both my local version and the server version and they both agree with each other all the way through until you get to the auth.php controller logged_in() routine where suddenly, at line 140 - the is_object($this-user) test - the $user object no longer exists!?!?!? The login() function call that calls the logged_in() function successfully passes the following test, which causes a redirect to the logged_in() function. if(Auth::instance()->login($user, $post['password'])) Yes, the password and hash, etc all work perfectly. Here is the offending code: public function logged_in() { if ( ! is_object($this->user)) { // No user is currently logged in url::redirect('auth/login'); } etc... } As the code is the same between my local installation and the server, I reckon it must be some server setting that is messing with me. FYI: All the rest of the code works because I have a temporary backdoor available that allows me to use the application (view pages of tables, etc) without being logged in. Any ideas?

  • How to disable ^C from being echoed on Linux on Ctrl-C

    - by pts
    When I press Ctrl-C in any pseudoterminal (xterm, gnome-terminal, rxvt, text console and SSH) in Karmic Koala, the string ^C gets echoed to the terminal in Ubuntu Karmic Koala. This hasn't happened in Ubuntu Jaunty Jackalope. I'd like to get rid of the extra ^C. Example: $ cat foo foo ^C $ _ I got the above by typing C, A, T, Enter, F, O, O, Enter, Ctrl-C. I want to get rid of the ^C, and get this for the same keypresses: $ cat foo foo $ _ I tried setting stty -echoctl, which created a single-character HT (or a box with Unicode 0003 in it) instead of the ^C. I want to see absolutely nothing when I press Ctrl-C. I'm using Linux linux 2.6.31-20-generic-pae #57-Ubuntu SMP Mon Feb 8 10:23:59 UTC 2010 i686 GNU/Linux

  • Source folders for a maven project in eclipse

    - by 4NDR01D3
    Hello all, I have a that uses maven... and I want to put it in my working environment with eclipse(Galileo)... the project is in a svn server, and I can create check out the project and everything looks OK. I even can run the unit test and everything is working there. However, now that everything is there I wanted to work in the code, and oh surprise there are no packages in my project... I mean all the source code is in the src folder and browsing through it i can see all my files, ut if I open the files from there, the files are opened as text files with no coloring, but worst no help at all about errors in compilation. I don't know what im I doing wrong now, because I had the same project in other machine and it was working well. So here is what I did, please let me know if you notice if I did something wrong, miss any steps or anything that can help me: In the SVN Repository (Using subclipse 1.6.10) I added my SVN Repository Browsed to the folder where I have the pom file Right Click Check out as a Maven project...(Using m2eclipse 0.10.020100209) Used the default options and finish. The projects were created with no problem. I said projects because this maven project has modules, and each module became a project in eclipse. Back in the java perspective, Right click in the project, Run as maven test(Using JWebUnitTest, because I am testing a servlet) BUILD SUCCESS!! But as I said there is not packages so I can't really develop in this environment. Any help?? Thanks!

  • Strange results while measuring delta time on Linux

    Folks, could you please explain why I'm getting very strange results from time to time using the the following code: #include <unistd.h> #include <sys/time.h> #include <time.h> #include <stdio.h> int main() { struct timeval start, end; long mtime, seconds, useconds; while(1) { gettimeofday(&start, NULL); usleep(2000); gettimeofday(&end, NULL); seconds = end.tv_sec - start.tv_sec; useconds = end.tv_usec - start.tv_usec; mtime = ((seconds) * 1000 + useconds/1000.0) + 0.5; if(mtime > 10) printf("WTF: %ld\n", mtime); } return 0; } (You can compile and run it with: gcc test.c -o out -lrt && ./out) What I'm experiencing is sporadic big values of mtime variable almost every second or even more often, e.g: $ gcc test.c -o out -lrt && ./out WTF: 14 WTF: 11 WTF: 11 WTF: 11 WTF: 14 WTF: 13 WTF: 13 WTF: 11 WTF: 16 How can this be possible? Is it OS to blame? Does it do too much context switching? But my box is idle( load average: 0.02, 0.02, 0.3). Here is my Linux kernel version: $ uname -a Linux kurluka 2.6.31-21-generic #59-Ubuntu SMP Wed Mar 24 07:28:56 UTC 2010 i686 GNU/Linux

  • Changing the Hibernate 3 settings

    - by Bogdanel
    I use Hibernate3 and Hibernate Tools 3.2.4 to generate hbm.xml and java files and I want to use List instead of HashSet(...). I've tried to modify the hbm.xml files, putting list instead of set. Is there any way to specify to hibernate tools that I want to generate automatically a list not a HashSet? This is an exemple: Java class public class Test implements java.io.Serializable { private Long testId; private Course course; private String testName; private Set<Question> questions = new HashSet<Question>( 0 ); } Test.hbm.xml: <set name="questions" inverse="true" lazy="true" table="questions" fetch="select"> <key> <column name="test_id" not-null="true" /> </key> <one-to-many class="com.app.objects.Question" /> ... </set> I thought that I could find a clue in the "reveng.xml" file, but I failed.

  • Rails 2.3.14 setting expire_after for sessions is ignored

    - by Sergii Shablatovych
    I have next config in my environment.rb: config.action_controller.session_store = :cookie_store config.action_controller.session = { :expire_after => 14.days, :domain => DOMAIN, :session_key => '_session', :secret => 'some_string' } Setting session_store to active_record_store or mem_cache_store didn't help. Also i've tried just setting cookie from controller (with all founded options for expire): cookies[:test] = { :value => 'test' , :expires => 3600.to_i.from_now.utc } In both ways all sessions and cookies are deleted after closing browser window - they are only for browser session. I've tried almost all variants founded in the Internet - no luck( My config is: Ubuntu 10.04 LTS, rails 2.3.14, ruby Enterprise Edition 1.8.7, Phusion Passenger version 3.0.11 and Nginx compiled by Phusion Passenger. I've an options that it's Nginx not allowing setting some headers but also didn't find any solution. Any help appreciated! Thanks UPD. i've tried to put all configs for sessions to config/initializers/session_store.rb - nothing changed. i have a feeling that it's not a rails problem. may it be phusion + nginx error? i don't even know how to check where the problem is.

  • PHP Object Creation and Memory Usage

    - by JohnO
    A basic dummy class: class foo { var $bar = 0; function foo() {} function boo() {} } echo memory_get_usage(); echo "\n"; $foo = new foo(); echo memory_get_usage(); echo "\n"; unset($foo); echo memory_get_usage(); echo "\n"; $foo = null; echo memory_get_usage(); echo "\n"; Outputs: $ php test.php 353672 353792 353792 353792 Now, I know that PHP docs say that memory won't be freed until it is needed (hitting the ceiling). However, I wrote this up as a small test, because I've got a much longer task, using a much bigger object, with many instances of that object. And the memory just climbs, eventually running out and stopping execution. Even though these large objects do take up memory, since I destroy them after I'm done with each one (serially), it should not run out of memory (unless a single object exhausts the entire space for memory, which is not the case). Thoughts?

  • Writing out sheet to text file using POI event model

    - by Eduardo Dennis
    I am using XLSX2CSV example to parse large sheets from a workbook. Since I only need to output the data for specific sheets I added an if statement in the process method to test for the specific sheets. When the condition is met I continue with the process. public void process() throws IOException, OpenXML4JException, ParserConfigurationException, SAXException { ReadOnlySharedStringsTable strings = new ReadOnlySharedStringsTable(this.xlsxPackage); XSSFReader xssfReader = new XSSFReader(this.xlsxPackage); StylesTable styles = xssfReader.getStylesTable(); XSSFReader.SheetIterator iter = (XSSFReader.SheetIterator) xssfReader.getSheetsData(); while (iter.hasNext()) { InputStream stream = iter.next(); String sheetName = iter.getSheetName(); if (sheetName.equals("SHEET1")||sheetName.equals("SHEET2")||sheetName.equals("SHEET3")||sheetName.equals("SHEET4")||sheetName.equals("SHEET5")){ processSheet(styles, strings, stream); try { System.setOut(new PrintStream( new FileOutputStream("C:\\Users\\edennis.AD\\Desktop\\test\\"+sheetName+".txt"))); } catch (Exception e) { e.printStackTrace(); } stream.close(); } } } But I need to output text file and not sure how to do it. I tried to use the System.set() method to output everything from system.out to text but that's not working I just get blank files.

  • Packages name conflicting with getters and setters?

    - by MrKishi
    Hello, folks. So, I've came across this compilation error a while ago.. As there's an easy fix and I didn't find anything relevant at the time, I eventually let it go. I just remembered it and I'm now wondering if this is really part of the language grammar (which I highly doubt) or if it's a compiler bug. I'm being purely curious about this -- it doesn't really affect development, but it would be nice to see if any of you have seen this already. package view { import flash.display.Sprite; public class Main extends Sprite { private var _view:Sprite = new Sprite(); public function Main() { this.test(); } private function test():void { trace(this.view.x, this.view.y); //1178: Attempted access of inaccessible property x through a reference with static type view:Main. //1178: Attempted access of inaccessible property y through a reference with static type view:Main. //Note that I got this due to the package name. //It runs just fine if I rename the package or getter. } public function get view():Sprite { return this._view; } } }
