  • jEdit+JythonInterpreter: how to import java class?

    - by JChao
    Hi, I'm running jEdit with the JythonInterprete and I have a .jar file called JavaTest.jar. JavaTest has a class called SampleJavaClass which has a method printerCount. From my .py file, I want to do: from javatest import SampleJavaClass class SampleClass(SampleJavaClass): def pymain(self): SampleJavaClass.printerCount(4) Java code: package javatest; public class SampleJavaClass { public static void printerCount(int i){ for(int j=0; j< i; j++){ System.out.println("hello world"); } } (etc...) In the JythonInterpreter, I have already tried clicking "Edit Jython Path" and adding the .jar file then running the interpreter again, but it still gives me ImportError: cannot import name SampleJavaClass

  • XAML Multi-Level Binding Source/Path Issue

    - by tpartee
    So I have this issue I've been trying various ways to tackle all day and nothing's catching and working for it. Basically I have a XAML object called ChromeWindow (derived from Window) which has in it's code-behind a DependencyProperty called AppChrome which stores a reference to an associated ApplicationChrome XAML object (derived from UserControl). ApplicationChrome's XAML file has a few x:Name'd objects (a TextBlock and Border for instance) to which I want to bind to from the ChromeWindow's XAML. The root of the ChromeWindow is x:Name'd as 'rootWindow' in the XAML, so I figured one of these bindings would work: {Binding ElementName=rootWindow, Path=AppChrome.CaptionTextBlock.Text, Mode=OneWay} But that complains of a BindingExpression path error such that the property 'CaptionTextBlock' (an x:Name'd TextBlock in AppChrome's XAML) cannot be found on object of type ApplicationChrome So I tried this binding intead: {Binding Source=AppChrome.CaptionTextBlock, Path=Text, Mode=OneWay} And still no luck, this time complaints of a BindingExpression path error again, but this time that it cannot find the 'CaptionTextBlock' property on object of type String I know I'm missing something really simple here, please help! ;D

  • In Drupal, can you control block display according to e.g. number of URL parts?

    - by james6848
    I'm having a little trouble controlling page-specific block display in Drupal... My URL's will be of this typical structure: http://www.mysite.co.uk/section-name/sub-page/sub-sub-page The 'section-name' will effectively be fixed, but there will be many sub-pages (far too many to explicitly reference). I need to somehow control block display as follows: One block will show on all pages where URL contains 'section-name/sub-page' but not on pages 'section-name/sub-page/sub-sub-page' Conversely, another block will show on all pages where URL contains 'section-name/sub-page/sub-sub-page' but not on pages 'section-name/sub-page' My only idea is to do a bit of PHP that looks for the string 'section-name' and then also counts URL parts (or even the number of slashes). Not sure how to implement that though :) Your help would be appreciated!

  • JAR file folder for eclipse projects

    - by Daff
    I'm trying to create a centralized folder (in some kind of a "meta project" in my eclipse workspace) for commonly used JAR files for referenced projects in this workspace. It should work similar to the WEB-INF/lib folder for web projects but also apply to non web projects, and automatically scan and add all jar files in this folder. I tried to create a user library with these jar files and reference them in the project but I still have to add every new jar manually to the user library (and don't know if it is referenced relative of absoulute) and Tomcat (WTP) doesn't seem to take these files (Run As - Run on Server) into its classpath (and I don't want to duplicate the jars and put them into WEB-INF/lib). Any ideas?

  • Java training for .NET developers?

    - by C Keene
    We are working with a large retail bank on training 40-50 .Net developers to use Java. They are familiar with C# and .Net framework and have built dozens of "run the business" style apps in .Net. We need advice on how to provide basic Java familiarity, with a focus on back end logic, security and transaction management. Back end is Spring/Hibernate, front end is Ajax (Dojo). Are there any online, self-paced, Java courses that would be good for C#/.Net developers to get up to speed quickly?

  • super-space-optimized code

    - by Will
    There are key self-contained algorithms - particularly cryptography-related such as AES, RSA, SHA1 etc - which you can find many implementations of for free on the internet. Some are written to be nice and portable clean C. Some are written to be fast - often with macros, and explicit unrolling. As far as I can tell, none are trying to be especially super-small - so I'm resigned to writing my own - explicitly AES128 decryption and SHA1 for ARM THUMB2. What patterns and tricks can I use to do so? Are there compilers/tools that can roll-up code?

  • Transparently storing class state without exposing implementation

    - by RoToRa
    I have a model (MVC) class whose internal state (which basically contains of private int fields) I want to store. The program is running on Android (for now) so I need to store the in a Bundle, but I'll be using the same class later in a desktop application where I'll have to store the state some other way, so I can't reference Bundle directly in my class. So my question is: What is the best way to store (and retrieve) the state of a class without exposing it's implementation? The best I could think of removing the private access modifier so that the fields become package accessible and create read/write helper classes in the same package, but that somehow seems wrong.

  • Image Size for Animation!

    - by taimur-hamza
    Hi Everybody, I m new to iphone app development and i need some help. I have a list of 30 images that i have to animate and display with 0.1 second interval. I put all the images in an Array using this imageletter.animationImages = [NSArray arrayWithObjects:[UIImage imageNamed:@"1.png"], ...... ,nil] And then animate it using these statements, [imageletter setAnimationDuration:16]; [imageletter startAnimating]; [NSTimer scheduledTimerWithTimeInterval:mytime target:self selector:@selector(StopAfterCertainTime) userInfo:nil repeats:NO]; Now the problem is that the size of each image is 8kb , it runs fine on iphone simulator but crashes on device. When i used 30 other images of 4kb each it runs fine both on simulator and device. Can anybody tell me what is the ideal size for such kind of task. Thanks

  • Missing type or namespace name

    - by Psytronic
    This is an odd one, not one I've come across before. My project complies and runs fine if I have my classes in the root folder (Not in App_Code). As soon as I move them into the App_Code folder then it will compile, but running it will bring up the old CS0234: The type or namespace name 'Linq' does not exist in the namespace 'System.Data' (are you missing an assembly reference?) I don't understand how moving the class(es) to the App_Code folder causes the whole thing to fall apart there? Project target is .Net 4 on VWD 2010 Express

  • Call random function on percents?

    - by Angelena Godkin
    I cannot figure this out. I need a solution to call a random function for it's percent. Ex. there is 10% chances that the script calls subscriptions() and 3% chance that the system call the function "specialitems()". I am stuck in this, so i hope someone can help me with this brainkiller. <?php class RandomGifts { public $chances = ''; public function __construct($user) { $this->user = $user; //Find percent for each function $this->chances = array( 'subscriptions' => 10, // 10% 'specialitems' => 3, // 5% 'normalitems' => 30, // 40% 'fuser' => 50, // 70% 'giftcards' => 7, // 7% ); //This should call the function which has been calculated. self::callFunction(?); } public function subscriptions(){} public function specialitems(){} public function normalitems(){} public function fuser(){} public function giftcards(){} } ?>

  • Android: Referring to a string resource when defining a log name

    - by spookypeanut
    In my Android app, I want to use a single variable for the log name in multiple files. At the moment, I'm specifying it separately in each file, e.g. public final String LOG_NAME = "LogName"; Log.d(LOG_NAME, "Logged output); I've tried this: public final String LOG_NAME = (String) getText(R.string.app_name_nospaces); And while this works in generally most of my files, Eclipse complains about one of them: The method getText(int) is undefined for the type DatabaseManager I've made sure I'm definitely importing android.content.Context in that file. If I tell it exactly where to find getText: Multiple markers at this line - Cannot make a static reference to the non-static method getText(int) from the type Context - The method getText(int) is undefined for the type DatabaseManager I'm sure I've committed a glaringly obvious n00b error, but I just can't see it! Thanks for all help: if any other code snippets would help, let me know.

  • Objective-C why doesn't my array of array works?

    - by Quetsche
    This is probably a completely stupid question, but i'm pretty new at objective-C and programing in general. i'm trying to make an array of arrays but can't manage to make it work : @interface ArraysAndDicts : NSObject { NSMutableArray * mySimpleArray; NSMutableArray * myComplicatedArray; } the implementation : -(void)generateValueForArrayOfArrays { [self generateValueForArray]; //this generates an array with 5 elements 'mySimpleArray' [myComplicatedArray addObject:mySimpleArray]; NSMutableArray * mySecondaryArray = [[NSMutableArray alloc] init]; [mySecondaryArray addObject:@"twoone"]; [mySecondaryArray addObject:@"twotwo"]; [myComplicatedArray addObject:mySecondaryArray]; (i edited out all the NSLogs for clarity) When running my app, the console tells me : mySecondaryArray count = 2 mySimpleArray count = 5 myComplicatedArraycount = 0 So, i know there are other ways to make multidimensional arrays, but i'd really like to know why this doesn't work. Thank you.

  • how to create english language dictionary application with python (django)?

    - by sintaloo
    Hi All, I would like to create an online dictionary application by using python (or with django). It will be similar to http://dictionary.reference.com/. My question is (1) Are there any existing open source python package or modules or application which implements this functionality that I can use or study from? (2) If the answer to the first question is NO. which algorithm should I follow to create such web application? Can I simply use the python built-in dictionary object for this job? so that the dictionary object's key will be the english word and the value will be the explanation. is this OK in term of performance? OR Do I have to create my own Tree Object to speed up the search? or any existing package which handles this job properly? Thank you very much.

  • Annotation based data structure visualization - are there similar tools out there?

    - by Helper Method
    For a project at university I plan to build an annotation based tool to visualize/play around with data structures. Here's my idea: Students which want to try out their self-written data structures need to: mark the type of their data structures using some sort of marker annotation e.g. @List public class MyList { ... } so that I know how to represent the data structure need to provide an iterator so that I can retrieve the elements in the right order need to annotate methods for insertion and removal, e.g. @add public boolean insert(E e) { ... } so that I can "bind" that method to some button. Do similar applications exist? I googled a little bit around but didn't find anything like that.

  • Nuget and Source Control Files to Exclude?

    - by Peter Kellner
    I know I should be using nuget more but at this point I don't completely understand the nuances so I still tend to either get source and build the project, then reference the project, or I create my own "dlls" folder and hand copy the dll's in. As part of my learning process, I'm trying to understand what is critical and what is not when using nuget. For example, I've done install-package restsharp and now when I check into source control, I get files like "packages/RestSharp.103.4/lib/net4/RestSharp.xml". I'm assuming that nuget will help me with upgrading and such and it needs to have certain meta data type files. My question is: Should I be ignoring any or all files in the "packages" directory? If so, what and why. Thanks

  • Advanced find in Rails

    - by jriff
    Hi all I really suck at Rails' finders besides the most obvious. I always resort to SQL when things get more advanced than Model.find(:all, :conditions => ['field>? and field<? and id in (select id from table)', 1,2]) I have this method: def self.get_first_validation_answer(id) a=find_by_sql(" select answers.*, answers_registrations.answer_text from answers_registrations left join answers on answers_registrations.answer_id=answers.id where (answers_registrations.question_id in (select id from questions where validation_question=true)) and (sale_registration_id=#{id}) limit 1 ").first a.answer_text || a.text if a end Can someone create a find method that gets me what I want?

  • What's the recommended way to create an HTML elemnt and bind a listener to it using jQuery?

    - by Bytecode Ninja
    At the moment I achieve this using something like this: var myElem = "<tr id='tr-1'><td>content</td></tr>"; $("#myTable").append(myElem); $("#tr-1").click(function() { // blah blah }); Traditionally, when I wasn't using jQuery, I used to do something like this: var myElem = document.createElement(...); var myTable = document.getElementById("myTable"); myTable.appendChild(myElem); myElem.onclick = function() { // blah blah } The thing is, in the second approach I already have a reference to myElem and I don't have to scan the DOM ($("#tr-1")) to find it, like the jQuery approach, and hence it should be much faster especially in big pages. Isn't there a better jQuery-ish way to accomplish this task?

  • How would one call std::forward on all arguments in a variadic function?

    - by Noah Roberts
    I was just writing a generic object factory and using the boost preprocessor meta-library to make a variadic template (using 2010 and it doesn't support them). My function uses rval references and std::forward to do perfect forwarding and it got me thinking...when C++0X comes out and I had a standard compiler I would do this with real variadic templates. How though, would I call std::forward on the arguments? template < typename ... Params void f(Params ... params) // how do I say these are rvalue reference? { y(std::forward(...params)); //? - I doubt this would work. } Only way I can think of would require manual unpacking of ...params and I'm not quite there yet either. Is there a quicker syntax that would work?

  • Generating incremental numeric column values during INSERT SELECT statement

    - by Charles
    I need to copy some data from one table to another in Oracle, while generating incremental values for a numeric column in the new table. This is a once-only exercise with a trivial number of rows (100). I have an adequate solution to this problem but I'm curious to know if there is a more elegant way. I'm doing it with a temporary sequence, like so: CREATE SEQUENCE temp_seq START WITH 1; INSERT INTO new_table (new_col, copied_col1, copied_col2) SELECT temp_seq.NEXTVAL, o.* FROM (SELECT old_col1, old_col2 FROM old_table) o; DROP SEQUENCE temp_seq; Is there way to do with without creating the sequence or any other temporary object? Specifically, can this be done with a self-contained INSERT SELECT statement? There are similar questions, but I believe the specifics of my question are original to SO.

  • Create categorial variable in R based on range

    - by Stedy
    I have a dataframe with a column of integers that I would like to use as a reference to make a new categorical variable. I want to divide the variable into three groups and set the ranges myself (ie 0-5, 6-10, etc). I tried cut but that divides the variable into groups based on a normal distribution and my data is right skewed. I have also tried to use if/then statements but this outputs a true/false value and I would like to keep my original variable. I am sure that there is a simple way to do this but I cannot seem to figure it out. Any advice on a simple way to do this quickly?

  • Iphone Orientation Change

    - by SG
    I am trying to implement orientation change functionality in my application.I have overrided -(void) didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation. In this method i change the frame size of the tableview(including the position of the cell items) which is present in the view. The tableview Details: Added to the view as [self.view addSubView:tableView] in the viewDidLoad method of the view controller; Cell item (row) has a textfield and a segmented control. There are 10 cells in the table view and in landscape mode only 2 cells are visible and in potrait mode 5 cells are visible. I have implemented scroller. Issue: Certain times on changing the orientation to potrait mode certain segmented controls in the cell are not rendered (Not shown at all). This happens when i am viewing the last couple of cells in the landscape mode and i change the orientation to potrait mode.
