  • C#, finding the largest prime factor of a number

    - by Juan
    Hello! I am new at programming and I am practicing my C# programming skills. My application is meant to find the largest prime factor of a number entered by the user. But my application is not returning the right answer and I dont really know where the problem is. Can you please help me? using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Console.WriteLine("Calcular máximo factor primo de n. De 60 es 5."); Console.Write("Escriba un numero: "); long num = Convert.ToInt64(Console.ReadLine()); long mfp = maxfactor(num); Console.WriteLine("El maximo factor primo es: " + num); Console.Read(); } static private long maxfactor (long n) { long m=1 ; bool en= false; for (long k = n / 2; !en && k > 1; k--) { if (n % k == 0 && primo(k)) { m = k; en = true; } } return m; } static private bool primo(long x) { bool sp = true; for (long i = 2; i <= x / 2; i++) { if (x % i == 0) sp = false; } return sp; } } }

  • return sql query in xml format in python

    - by Ramy
    When I first started working at the company that i work at now, I created a java application that would run batches of jasper-reports. In order to determine which parameters to use for each report in the set of reports, I run a sql query (on sqlserver). I wrote the application to take an xml file with a set of parameters for each report to be generated in the set. so, my process has become, effectively, three steps: run the sql query and return the results in XML format (using 'for XML auto') run the results of the sql query through an XSLT transformation so the xml is formatted in such a way that is friendly with the java application i wrote. run the java application with that final xml file As you can imagine, what I'd like to do is accomplish these steps in python, but i'm not quite sure how to get started. I know how to run an SQL query in Python. I see plenty of documentation about how to write your own xml document with Python. I even see documentation for xsl transformations in python. the big question is how to get the results of the sql query in XML through python. Any and all pointers would be very valuable. Thanks, _Ramy

  • segfault during __cxa_allocate_exception in SWIG wrapped library

    - by lefticus
    While developing a SWIG wrapped C++ library for Ruby, we came across an unexplained crash during exception handling inside the C++ code. I'm not sure of the specific circumstances to recreate the issue, but it happened first during a call to std::uncaught_exception, then after a some code changes, moved to __cxa_allocate_exception during exception construction. Neither GDB nor valgrind provided any insight into the cause of the crash. I've found several references to similar problems, including: http://wiki.fifengine.de/Segfault_in_cxa_allocate_exception http://forums.fifengine.de/index.php?topic=30.0 http://code.google.com/p/osgswig/issues/detail?id=17 https://bugs.launchpad.net/ubuntu/+source/libavg/+bug/241808 The overriding theme seems to be a combination of circumstances: A C application is linked to more than one C++ library More than one version of libstdc++ was used during compilation Generally the second version of C++ used comes from a binary-only implementation of libGL The problem does not occur when linking your library with a C++ application, only with a C application The "solution" is to explicitly link your library with libstdc++ and possibly also with libGL, forcing the order of linking. After trying many combinations with my code, the only solution that I found that works is the LD_PRELOAD="libGL.so libstdc++.so.6" ruby scriptname option. That is, none of the compile-time linking solutions made any difference. My understanding of the issue is that the C++ runtime is not being properly initialized. By forcing the order of linking you bootstrap the initialization process and it works. The problem occurs only with C applications calling C++ libraries because the C application is not itself linking to libstdc++ and is not initializing the C++ runtime. Because using SWIG (or boost::python) is a common way of calling a C++ library from a C application, that is why SWIG often comes up when researching the problem. Is anyone out there able to give more insight into this problem? Is there an actual solution or do only workarounds exist? Thanks.

  • Access 2003 VBA: Return only the index of the last item selected in a ListBox

    - by Eric D. Johnson
    I will preface this with saying, this is my first time using listboxes and earlier posts were criticized for lacking detail. So, all help is greatly appreciated and I hope this is enough information without being overkill. Currently, I have a listbox updating a junction table with an on click event (iterates through selected items and if they are not in the table it adds them). The list box is also updated by an option group (based on the option group value a query populates the list with the appropriate items and they are selected/highlighted based on the junction table). Also, when items are a "sub-category" the "category" is also selected. This functions perfectly until I ask it to do more... Problem 1: I need to differentiate "categories" of items from each other. So, I have included a blank item to the list box to add a space between categories. When the blank items are present the listbox does not update the junction table properly and vice versa. Problem 2: My users want to be able to deselect the "category" under certain circumstances. This is fine, just de-select the "category" after the "sub-category" is selected. However, the "category" is re-selected whenever the listbox is clicked again because it iterates through all entries. Perceived solution for both problems: Return only the index of the item (de)selected and manipulate accordingly. Is this possible? If so, how? OR: Should I take a different approach?

  • How do I make a third party .jar available to my .jsp page?

    - by Matthew
    I'm just starting to learn JSP (and I'm pretty new to Java in general), and I'd like to use JSON-lib with it. I want to make a page something like this: <%@ page import="net.sf.json.JSONObject"%> <% String json = new JSONObject().put("hello", "world").toString(); out.println(json); %> I downloaded json-lib-2.3-jdk15.jar and put it in the same directory as the .jsp page. But I get this error org.apache.jasper.JasperException: Unable to compile class for JSP: An error occurred at line: 6 in the generated java file Only a type can be imported. net.sf.json.JSONObject resolves to a package An error occurred at line: 3 in the jsp file: /getCard.jsp JSONObject cannot be resolved to a type 1: <%@ page import="net.sf.json.JSONObject" %> 2: <% 3: String json = new JSONObject().put("hello", "world").toString(); 4: out.println(json); 5: %> 6: How do I make the JSONObject class available to my .jsp page?

  • Reducing Time Complexity in Java

    - by Koeneuze
    Right, this is from an older exam which i'm using to prepare my own exam in january. We are given the following method: public static void Oorspronkelijk() { String bs = "Dit is een boodschap aan de wereld"; int max = -1; char let = '*'; for (int i=0;i<bs.length();i++) { int tel = 1; for (int j=i+1;j<bs.length();j++) { if (bs.charAt(j) == bs.charAt(i)) tel++; } if (tel > max) { max = tel; let = bs.charAt(i); } } System.out.println(max + " keer " + let); } The questions are: what is the output? - Since the code is just an algorithm to determine the most occuring character, the output is "6 keer " (6 times space) What is the time complexity of this code? Fairly sure it's O(n²), unless someone thinks otherwise? Can you reduce the time complexity, and if so, how? Well, you can. I've received some help already and managed to get the following code: public static void Nieuw() { String bs = "Dit is een boodschap aan de wereld"; HashMap<Character, Integer> letters = new HashMap<Character, Integer>(); char max = bs.charAt(0); for (int i=0;i<bs.length();i++) { char let = bs.charAt(i); if(!letters.containsKey(let)) { letters.put(let,0); } int tel = letters.get(let)+1; letters.put(let,tel); if(letters.get(max)<tel) { max = let; } } System.out.println(letters.get(max) + " keer " + max); } However, I'm uncertain of the time complexity of this new code: Is it O(n) because you only use one for-loop, or does the fact we require the use of the HashMap's get methods make it O(n log n) ? And if someone knows an even better way of reducing the time complexity, please do tell! :)

  • Where do I put jar files in Tomcat 6?

    I am having trouble getting my JSP page to load a Java class which is in a jar file. The message I get appears to indicate a class not found exception: Jan 6, 2011 12:21:45 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet jsp threw exception org.apache.jasper.JasperException: Unable to compile class for JSP: An error occurred at line: 72 in the jsp file: /xmlloader.jsp FactArray cannot be resolved to a type 69: sourceType = "1"; 70: } 71: 72: FactArray fa = new FactArray(); 73: Fact f; 74: 75: /***********************/ The Type FactArray is one of my classes in a package com.mypackage.fact.FactArray which exists in myjar.jar. myjar.jar is a separate Java project (using NetBeans, but I don't think that's relevant).

  • Global resources can't be resolved after publishing Website in VS2008

    - by Scoregraphic
    Hi there I have a web-project running in VS 2008. We have some global resource files (*.resx) in the App_GlobalResources folder for internationalisation. All this works like a charm on my local IIS installation out of VS. But when I publish my web-project to the local filesystem and/or another server, all the resources can no longer be found. So I guess the pre-compilation is somehow corrupting stuff. When I call the pre-compiled web, I get an error that the resource object with key xyz cannot be found, although it could be found before. I checked with .NET reflector if the resource stuff made it into the *.dlls. All those identifiers are there (bin/Web.dll, bin/<culture>/Web.resources.dll). The identifiers are loaded like this: <asp:MenuItem NavigateUrl="~/OrderNew.aspx" Text="<%$ Resources:MyProject, MenuNewOrder %>" Value="NewOrder"> The resource files are called MyProject.resx and MyProject.<culture>.resx where <culture> corresponds the the specific culture (i.e. MyProject.de-DE.resx). Any ideas how to solve this? I really appreciate any help. Thanks Edit: If I copy the App_GlobalResources folder manually to the output, the resources may be loaded normally. So I really really wonder what this pre-compilation is all about. I'm still interested in solving the issue "the right way".

  • Design PDF template and populate data at runtime using java,xml etc..

    - by Samant
    well i have been looking for a java based PDF solutions...we dont have a clean way i guess-still.. all solutions are primitive and kind of workarounds... No easy solution for this requirement - 1. Designing a PDF template using a IDE (eg. Livecycle designer ..which is not free) 2. Then at runtime using java, populate data into this PDF template...either using xml or other datasources... such a simple requirement and NONE has a good "open-source and free" solution yet ! Is anyone aware of any ? I have been searching for since 3-4 years now..for a clean way out... Eclipse BIRT comes close.. but does not handle Barcode elements ..OOB. Jasper - ireport is also good but that tool does not have a table concept and is kind of annoying ! Also barcode support is not good. XSL-FO has not free IDE for design . Looking for a better answer .. got one ?

  • Google Analytics - Goals - Advanced Segments - Does it keep cookies for tracking visitors?

    - by Kuko
    Hi there, I am working with Google Analytics - Goals and Funnels for quite sometime, but one thing is is not clear for me. I would very much appreciate if you could help me. We are advertising on several sites rotating several different ads. Our main goal is to collect as many sign-ups (new users) as possible for as low price as possible. We use to advertise the way, that each ad has the same URL where to land, but contains different parameter (e.g. http://www.brautpunkt.de/?ref=fb01 or ..... .de/?ref=adw03). My question is: If I am looking at the goals (Goals Overview), filtering it through Advanced Segments (Landing Page contains /?ref=fb01) is this subset of goals done only by the users who registered in the same session after they came on our site directly from the ad? or also by those users who came first time through this ad (/?ref=fb01), didn't register in the same session but came directly for example on the other day and register than? Thank you very much in advance for your advice. Peter

  • Implementation of delegates in C#

    - by Ram
    Hi, I am trying to learn on how to use delegates efficiently in C# and I was just wondering if anyone can guide me through... The following is a sample implementation using delegates... All I am doing is just passing a value through a delegate from one class to another... Please tell me if this is the right way to implement... And also your suggestions... Also, please note that I have de-registered the delegate in : void FrmSample_FormClosing(object sender, FormClosingEventArgs e) { sampleObj.AssignValue -= new Sample.AssignValueDelegate(AssignValue); } Is this de-registration necessary? The following is the code that I have written.. public partial class FrmSample : Form { Sample sampleObj; public FrmSample() { InitializeComponent(); this.Load += new EventHandler(FrmSample_Load); this.FormClosing += new FormClosingEventHandler(FrmSample_FormClosing); sampleObj = new Sample(); sampleObj.AssignValue = new Sample.AssignValueDelegate(AssignValue); } void FrmSample_FormClosing(object sender, FormClosingEventArgs e) { sampleObj.AssignValue -= new Sample.AssignValueDelegate(AssignValue); } void FrmSample_Load(object sender, EventArgs e) { sampleObj.LoadValue(); } void AssignValue(string value) { MessageBox.Show(value); } } class Sample { public delegate void AssignValueDelegate(string value); public AssignValueDelegate AssignValue; internal void LoadValue() { if (AssignValue != null) { AssignValue("This is a test message"); } } } Pls provide your feedback on whether this is right... Thanks, Ram

  • Can this be done in 1 line?

    - by Angelo
    Can this be done in 1 line with PHP? Would be awesome if it could: $out = array("foo","bar"); echo $out[0]; Something such as: echo array("foo","bar")[0]; Unfortunately that's not possible. Would it be possible like this? So I can do this for example in 1 line: echo array(rand(1,100), rand(1000,2000))[rand(0,1)]; So let's say I have this code: switch($r){ case 1: $ext = "com"; break; case 2: $ext = "nl"; break; case 3: $ext = "co.uk"; break; case 4: $ext = "de"; break; case 5: $ext = "fr"; break; } That would be much more simplified to do it like this: $ext = array("com","nl","co.uk","de","fr")[rand(1,5)];

  • My UITableView has duplicated rows

    - by Mark
    Im not sure why, but my UITableView, which isnt anything fancy, is showing repeating rows when it shouldnt be. It seems that the rows that get added when the user scrolls (i.e. the rows that are off the screen to start with) are getting the data for the wrong row index. Its almost like when a new cell is de-queued, it's using a cell that 'was' used, but wasn't cleaned up correctly. Do you need to 'clean up' cells that are de-queue so that new cells dont use cells that are already created? my code is as below: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CustomCellIdentifier = @"CustomCellIdentifier"; MyDayCell *cell = (MyDayCell *)[tableView dequeueReusableCellWithIdentifier: CustomCellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"MyDayCell" owner:self options:nil]; for (id oneObject in nib) if ([oneObject isKindOfClass:[MyDayCell class]]) cell = (MyDayCell *)oneObject; } NSUInteger section = [indexPath section]; NSUInteger row = [indexPath row]; NSArray *thisSectionItems = (NSArray*)[self.listData objectForKey: [[NSNumber alloc] initWithInt:section]]; MyDayDetails *rowData = [thisSectionItems objectAtIndex:row]; //setup my cells data here... return cell; } Is there anything wrong with this code? has anyone seen anything like this before?

  • iPhone: Helpful Classes or extended Subclasses which should have been in the SDK

    - by disp
    This is more a community sharing post than a real question. In my iPhone OS projects I'm always importing a helper class with helpful methods which I can use for about every project. So I thought it might be a good idea, if everyone shares some of their favorite methods, which should have been in everyones toolcase. I'll start with an extension of the NSString class, so I can make strings with dates on the fly providing format and locale. Maybe someone can find some need in this. @implementation NSString (DateHelper) +(NSString *) stringWithDate:(NSDate*)date withFormat:(NSString *)format withLocaleIdent:(NSString*)localeString{ NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; //For example @"de-DE", or @"en-US" NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:localeString]; [dateFormatter setLocale:locale]; // For example @"HH:mm" [dateFormatter setDateFormat:format]; NSString *string = [dateFormatter stringFromDate:date]; [dateFormatter release]; [locale release]; return string; } @end I'd love to see some of your tools.

  • Get part of array string

    - by user1560295
    Hello my output PHP code is : Array ( [country] => BG - Bulgaria ) ... and he comes from here : <?php $ip = $_SERVER['REMOTE_ADDR']; print_r(geoCheckIP($ip)); //Array ( [domain] => dslb-094-219-040-096.pools.arcor-ip.net [country] => DE - Germany [state] => Hessen [town] => Erzhausen ) //Get an array with geoip-infodata function geoCheckIP($ip) { //check, if the provided ip is valid if(!filter_var($ip, FILTER_VALIDATE_IP)) { throw new InvalidArgumentException("IP is not valid"); } //contact ip-server $response=@file_get_contents('http://www.netip.de/search?query='.$ip); if (empty($response)) { throw new InvalidArgumentException("Error contacting Geo-IP-Server"); } //Array containing all regex-patterns necessary to extract ip-geoinfo from page $patterns=array(); $patterns["country"] = '#Country: (.*?)&nbsp;#i'; //Array where results will be stored $ipInfo=array(); //check response from ipserver for above patterns foreach ($patterns as $key => $pattern) { //store the result in array $ipInfo[$key] = preg_match($pattern,$response,$value) && !empty($value[1]) ? $value[1] : ''; } return $ipInfo; } ?> How can I get ONLY the name of the Country like in my case "Bulgaria"? I think it will happen with preg_replace or substr but i dont know what is the better solution now.

  • Two Applications using the same index file with Hibernate Search

    - by Dominik Obermaier
    Hi, I want to know if it is possible to use the same index file for an entity in two applications. Let me be more specific: We have an online Application with a frondend for the users and an application for the backend tasks (= administrator interface). Both are running on the same JBOSS AS. Both Applications are using the same database, so they are using the same entities. Of course the package names are not the same in both applications for the entities. So this is our usecase: A user should be able to search via the frondend. The user is only allowed to see results which are tagged with "visible". This tagging happens in our admin interface, so the index for the frontend should be updated every time an entity is tagged as "visible" in the backend. Of course both applications do have the same index root folder. In my index folder there are 2 index files: de.x.x.admin.model.Product de.x.x.frondend.model.Product How to "merge" this via Hibernate Search Configuration? I just did not get it via the documentation... Thanks for any help!
