  • Is it possible get the functionality of namespaces inside a class?

    - by CowKingDeluxe
    I have the following code: Public Class Form1 Private Function Step1_Execute() As Boolean Return Step1_Verify() End Function Private Function Step1_Verify() As Boolean Return True End Function Private Function Step2_Execute() As Boolean Return Step2_Verify() End Function Private Function Step2_Verify() As Boolean Return True End Function End Class What I would like to do is be able to separate the code, similar to the following (which obviously doesn't work): Public Class Form1 Namespace Step1 Private Function Step1_Execute() As Boolean Return Step1_Verify() End Function Private Function Step1_Verify() As Boolean Return True End Function End Namespace Namespace Step2 Private Function Step2_Execute() As Boolean Return Step2_Verify() End Function Private Function Step2_Verify() As Boolean Return True End Function End Namespace End Class I would like the functionality of namespaces inside of a class, as in something that would let me call Step2.Execute() instead of having to put Step2_ in front of a whole bunch of functions. I don't want to have to create separate classes / modules for step1, step2, etc. Is there a way that I can accomplish namespace functionality from inside a class?

  • sigprocmask not working

    - by EpsilonVector
    I'm using sigprocmask as follows: void mask(){ sigset_t new_set,old_set; sigemptyset(&new_set); sigaddset(&new_set,SIGALRM); sigprocmask(SIG_BLOCK, &new_set, &old_set); } and to my surprise a function which prints a big list somehow gets interrupted by the signal, even though I invoke mask() at its beginning. It looks as if mask fails, since my function doesn't invoke any other functions and therefore nowhere in its run should an unmask() happen. What can cause sigprocmask to fail?

  • What is the use of reflection in Java/C# etc

    - by zengr
    I was just curious, why should we use reflection in the first place? // Without reflection Foo foo = new Foo(); foo.hello(); // With reflection Class cls = Class.forName("Foo"); Object foo = cls.newInstance(); Method method = cls.getMethod("hello", null); method.invoke(foo, null); We can simply create an object and call the class's method, but why do the same using forName, newInstance and getMthod functions? To make everything dynamic?

  • Infor PM (Business Intelligence solution)

    - by Andrew
    We are currently implementing the commercial Infor PM (Performance Management) package as a business intelligence tool. Infor PM website It is apparently used by over 1,000 companies around the world, but I have found scant information about it on the net except for what's on their own website. It covers the whole range of data warehousing and BI functions with: an OLAP environment an ETL tool a report writer (called Application Studio) an add-on to Excel to connect to the data in the cubes through a pivot table etc Does anyone have any experience with using this package? How does it compare to the big players in BI (Cognos, Microsoft SSAS, Business Objects, etc). Any pitfalls I should know about? On the other hand, does it do anything better than its competitors?

  • Is there a simple script to convert C++ enum to string?

    - by Edu Felipe
    Suppose we have some named enums: enum MyEnum { FOO, BAR = 0x50 }; What I googled for is a script (any language) that scans all the headers in my project and generates a header with one function per enum. char* enum_to_string(MyEnum t); And a implementation with something like this: char* enum_to_string(MyEnum t){ switch(t){ case FOO: return "FOO"; case BAR: return "BAR"; default: return "INVALID ENUM"; } } The gotcha is really with typedefed enums, and unnamed C style enums. Does anybody know something for this? EDIT: The solution should not modify my source, except for the generated functions. The enums are in an API, so using the solutions proposed until now is just not an option.

  • How to explicitly add a piece of code to a java project

    - by user435245
    Hi there, I’m working with Net beans IDE and I want to add a piece of code to my project in a way that the source code won’t be visible to the user who is running the project, I decided to export that piece of code as a jar file in eclipse and then add that jar file to the project. But unfortunately net beans does not let me import that. It says which it is expecting a . Or when I insert. It goes in to that class and I cannot import that jar file into the project by import instruction. Is there a command in net beans which creates and object from jar file and then makes access to the functions and classes of the jar file? Would you please give the format of that instruction? If you know a better way to do this task I would be so happy if you share it with me

  • Storing expression template functors

    - by UncaughtException
    Hello guys, at the moment I'm really interested in expression templates and want to code a library for writing and differentiating mathematical functions with a lambda-style syntax. At the moment, I'm able to write (_x * _x)(2); and get the correct result 4. But I would really like to do something like MathFunction f = _x * _x; f(2);, but I don't have any ideas on how to cope with the recursive expression templates on the right side. Is it possible to achieve this without using the 'auto'-Keyword instead of MathFunction or having to make the operator() virtual? Thanks for your help!

  • Converting a stopwatch time to milliseconds (regex)

    - by Nick
    I'm trying to figure out the best way to convert a string containing a time to an integer number of milliseconds. I'm using a suboptimal way using a bunch of preg_match()'s and some array handling, but I was wondering if there was an elegant way. Here are some example stopwatch times (some wouldn't actually be seen on a stopwatch but need to be converted anyway): 3:34:05.81 34:05 5 (just 5 seconds) 89 (89 seconds) 76:05 (76 minutes, 5 seconds) Millseconds will not extend past 2 decimal places. You can give me an example using either PHP or Javascript regex functions. Thanks!

  • Are there any context-sensitive code search tools?

    - by Vicky
    I have been getting very frustrated recently in dealing with a massive bulk of legacy code which I am trying to get familiar with. Say I try to search for a particular function call, I get loads of results that turn out to be completely irrelevant; some of them are easy to spot, eg a comment saying // Fixed functionality in foo() so don't need to handle this here any more But others are much harder to spot manually, because they turn out to be calls from other functions in modules that are only compiled in certain cases, or are part of a much larger block of code that is #if 0'd out in its entirety. What I'd like would be a search tool that would allow me to search for a term and give me the choice to include or exclude commented out or #if 0'd out code. Then the search results would be displayed alongside a list of #defines that are required in order for that snippet of code to be relevant. I'm working in C / C++, but other than the specific comment syntax I guess the techniques should be more generally applicable. Does such a tool exist?

  • Drupal: How to render a form and table on same page

    - by Aaron
    Can someone help me render a form and table on the same page? I'm sure it's easy, but can't think of how to do it. Here's hook_menu: function ncbi_subsites_menu() { $items = array(); $items['admin/content/ncbi_subsites'] = array( 'title' => 'NCBI Subsites Module', 'description' => 'Informs Drupal about NCBI subsites as defined by the Content Inventory database', 'page callback' => 'ncbi_subsites_show_main_page', 'access arguments' => array( 'administer site configuration' ), 'type' => MENU_NORMAL_ITEM, ); return $items; } Here's the callback: function ncbi_subsites_show_main_page() { $subsites = ncbi_subsites_get_subsites_from_inventory(); // fnc returns associative array from inventory, defined in include return ncbi_subsites_make_table( $subsites ); } In the callback I call some helper functions that return a themed, paged table. What I want is a small form above the table. How would I that?

  • jQuery version of YAHOO.lang (isUndefined, isNull, isString etc.)

    - by Chris S
    Does anyone know of a jQuery plugin that has 'helpers' or extensions like those found in the YAHOO.lang namespace? I have in mind functions such as: isNull isDefined isString isFunction I would also appreciate the same kind of thing for strings and arrays, such as Contains, StartsWith (I know these are easy to write, I'm just looking for a plugin that encompasses them all). It's not in the YAHOO.lang namespace but also form related extensions- determining a radiobox's value (from the one checked), a form element's type in a friendly name. Specifically a plugin with fluent API rather than selector based such as $("input[@type=radio][@checked]") Again I'm aware they're easy to implement but I don't want to reinvent the wheel.

  • What is the status of jQuery's multi-argument content syntax: deprecated, supported, documented?

    - by Evan Carroll
    I've never seen this in any jQuery docs I've read; nor, have I ever seen it in the wild. I just observed multi-content syntax working here with jQuery 1.4.2. Is this supported syntax? Is it deprecated? $(".section.warranty .warranty_checks :last").after( $('<div class="little check" />').click( function () { alert('hi') } ) , $('<span>OEM</span>') /*Notice this (a second) argument */ ); I've never seen any indication in the jQuery grammar that any of the functions accept more than one argument (content) in such a fashion.

  • how to call a javascript function in the top frame?

    - by Rory
    This seems really simple, but how do I call a javascript function that's defined in the top-level html, from a child frame? top html doc - 1st level frame - 2nd level frame my top html doc has a function called testFn(). In the 2nd level frame I have a button with onclick="top.testFn();" but this doesn't call the testFn(). In Firebug if I use a watch to execute top.testFn(); it says TypeError: testFn() is not a function. Should this all just work - in which case it's a problem with my documents, or is there some other way to call functions in the top-level window?

  • Passing HTML using JSON

    - by ActionFactory
    Hi All, I'm passing Data using JSON to iPhone and iPad. One Field of Data is HTML. The problem is the encoding. Here's what I get back: > "GadgetHTML": "<strong>Hello</strong> > from Catworld<br />\n<img alt=\"\" > src=\"http://www.iconarchive.com/icons/fasticon/ifunny/128/dog-icon.png\" > />", The \ are killing me. The \n does not help. Any good way to do this? Any JSON to HTML Cleaning Functions? Encoding? (There must be something better than manually removing ) Thanks

  • Reordering Lists like playlists in the media player

    - by CrazyBS
    Hi, I have a list of items that are displayed using a ListView from a SQLCursor. The SQL table includes(as well as other things) a _id field and an order field. I use the order field to sort the list before it gets to the ListView. What I need is a widget like the MediaPlayer has in its playlist view. It allows you to click the icon and drag the item in the playlist around and put it into a new order. With that ability I can then retrieve the new order and update the SQL table with the new order. However, I am not having any luck finding any clues to help me add that functionality into my program. The question is whether I can use existing functions to help me, or do I need to manually program motion events and such until I get nearly the same functionality.

  • Send custom data when initializing java WebService over soap

    - by Mesni
    Hello. I have a question about sending additional data over soap to the functions. My webService function requests only one integer, for example an getDocumentPrivilage(DocumentID). In another WebService user registered and he got an unique ID, so the other application can see who he is. So on Service one he registers, gets id and it has to send it to the other webservice tor the privilage. Id dont wish to rewrite the function so that it gets the unique ID (like this getDocumentPrivilage(uniqID,DocumentID)) but, the wish is that i would be able to create a client that sends this data at the initialization or somehow as some sort of parameter behind the function. Is this possible?? I tried the ServiceLifecycle but cant see any setting i've given in. Im using WebSphere CE for the server and Jax-ws Creating the webapp in java. Thank you very much in advance. lp, Mesni

    I have an combobox poppulated with items from a database table. When I change the text i repopulate the combobox with items from the database table. But when I enter text and the list with suggestions opens no item in de list is selected. And i want a item to be selected so when you press enter that it becomes the selected item. This is a winforms application. Thanks. cbxNaam.Items.Clear(); string query = "SELECT bedr_naam FROM tblbedrijf WHERE bedr_naam LIKE '%" + cbxNaam.Text + "%'"; string[] bedrijfsnamen = Functions.DataTableToArray(Global.db.Select(query)); cbxNaam.Items.AddRange(bedrijfsnamen); cbxNaam.Select(cbxNaam.Text.Length + 1, 0);

  • Static member object of a class in the same class

    - by Luv
    Suppose we have a class as class Egg { static Egg e; int i; Egg(int ii):i(ii) {} Egg(const Egg &); //Prevents copy-constructor to be called public: static Egg* instance() {return &e} }; Egg Egg::e(47); This code guarantees that we cannot create any object, but could use only the static object. But how could we declare static object of the same class in the class. And also one thing more since e is a static object, and static objects can call only static member functions, so how could the constructor been called here for static object e, also its constructors are private.

  • Can this be done with multiple inhertance?

    - by Milo
    Here is what I would like to do. Say I have Class Widget. I then create Button from Widget. I then create ModifiedWidget which re-implements certain functions of Widget. I then want Button to use ModifiedWidget rather than plain Widget. Is this possible to do some how? Thanks class Button : public Widget; class SuperButton : public Button, public ModifiedWidget; I'm just not sure if that would do what I want it to though.

  • Correct handling of return data

    - by Serhiy
    Hello, I have a question related to correct handling of returns of the DAO library I'm writing for one project. This library probably is going to be used by another people and I want to do it correctly. So I would like to know, how I should deal with return statements of the functions of my DAO. Example 1 I have function to getCustomer which should return String. In case query doesn't return any result should I return null, empty string or throw some kind of Exception? Example 2 I have function getCutomerList which return ArrayList. In case query doesn't return any result should I return null, empty ArrayList or throw some Exception? Example 3 Some sql exception was detected, what should I do: throw exception or do try..catch of the block where it can occur? What is the "good" practice or "best" practice to apply in my case? Thanks on advance, Serhiy.

  • Wait for function to finish before executing the rest

    - by Wurlitzer
    When the user refreshes the page, defaultView() is called, which loads some UI elements. $.address.change() should execute when defaultView() has finished, but this doesn't happen all the time. $.address.change() cannot be in the success: callback, as it's used by the application to track URL changes. defaultView(); function defaultView() { $('#tout').fadeOut('normal', function() { $.ajax({ url: "functions.php", type: "GET", data: "defaultview=true", async: false, success: function (response) { $('#tout').html(response).fadeIn('normal'); } }); }); } $.address.change(function(hash) { hash = hash.value; getPage(hash); }); I'm at a loss as to how to make $.address.change() wait for defaultView() to finish. Any help would be appreciated.

  • Codeigniter error logs show a 404 non-existing images directory...need to worry?

    - by user342199
    I've recently started logging my errors through codeIgniter. Since doing so, I have noticed a lot of 404 errors for directories that don't exist. For example: ERROR - 2010-05-15 21:06:26 -- 404 Page Not Found -- someController/images Where someController is, obviously, a controller. The problem is, there are no functions within that controller called images, nor are there any links to a directory by that name. Could this be that someone is trying to hack my site? If so, do I need to worry? If not, why is this happening? Thanks, and forgive the newby-ness.

  • Inheritance - initialization problem

    - by dumbquestion
    I have a c++ class derived from a base class in a framework. The derived class doesn't have any data members because I need it to be freely convertible into a base class and back - the framework is responsible for loading and saving the objects and I can't change it. My derived class just has functions for accessing the data. But there are a couple of places where I need to store some temporary local variables to speed up access to data in the base class. mydata* MyClass::getData() { if ( !m_mydata ) { // set to NULL in the constructor m_mydata = some_long_and complex_operation_to_get_the_data_in_the_base() } return m_mydata; } The problem is if I just access the object by casting the base class pointer returned from the framework to MyClass* the ctor for MyClass is never called and m_mydata is junk. Is there a way of only initializing the m_mydata pointer once?

  • how to keep the value of a variable in a closure

    - by Florian Fida
    i need to create multiple javascript functions which have a static id inside, so the function itself knows what data to process. Here is some code: (function(){ function log(s){ if(console && console.log) console.log(s); else alert(s); } var i = 10; while (i--){ window.setTimeout(function(){ // i need i to be 10, 9, 8... here not -1 log(i); },500); } })(); The problem ist that i allways gets updated by the loop, and i need to prevent this. Thanks in advance for any help, comments or tips!

  • What is the best regular expression for validating email addresses?

    - by acrosman
    Over the years I have slowly developed a regular expression that validates MOST email addresses correctly, assuming they don't use an IP address as the server part. Currently the expression is: ^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$ I use this in several PHP programs, and it works most of the time. However, from time to time I get contacted by someone that is having trouble with a site that uses it, and I end up having to make some adjustment (most recently I realized that I wasn't allowing 4-character TLDs). What's the best regular expression you have or have seen for validating emails? I've seen several solutions that use functions that use several shorter expressions, but I'd rather have one long complex expression in a simple function instead of several short expression in a more complex function.
