  • Initializing a value through a Session variable

    - by William Calleja
    I need to Initialize a value in a Javascript by using a c# literal that makes reference to a Session Variable. I am using the following code <script type="text/javascript" language="javascript" > var myIndex = <%= !((Session["myIndex"]).Equals(null)||(Session["myIndex"]).Equals("")) ? Session["backgroundIndex"] : "1" %>; However the code above is giving me a classic Object reference not set to an instance of an object. error. Why? Shouldn't (Session["myIndex"]).Equals(null) capture this particular error?

  • Silverlight Windows Phone 7: Load Images From URL

    - by Lennie De Villiers
    Hi, I got the code below that is trying to load an image from the web into an Image control, when I run it I get an error on the given line that no network access is allowed: private void button1_Click(object sender, RoutedEventArgs e) { WebClient webClientImgDownloader = new WebClient(); webClientImgDownloader.OpenReadCompleted += new OpenReadCompletedEventHandler(webClientImgDownloader_OpenReadCompleted); webClientImgDownloader.OpenReadAsync(new Uri("http://dilbert.com/dyn/str_strip/000000000/00000000/0000000/000000/80000/5000/100/85108/85108.strip.print.gif", UriKind.Absolute)); } void webClientImgDownloader_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e) { BitmapImage bitmap = new BitmapImage(); bitmap.SetSource(e.Result); // ERROR HERE! image1.Source = bitmap; } Silverlight for Windows Phone 7

  • Request/Response objects

    - by Dan
    I'm planning on using CXF's rest implementation. I'm thinking of simply annotating my entity classes with jaxb annotations, such as @XmlRootElement, in order to create response objects. The benefit being avoidance of code duplication. As for the (client) request object, which will be used by a separate web app, I'm thinking of 'copying' the entity classes, removing the orm annotations, and adding jaxb annotations. Based on the above: Are there any dangers of creating request/response objects from entity classes? My entity classes contain relational properties, if I were to annotate them with @XmlRootElement, how can I stop the relational properties from being added (or considered apart of) to the response object? Is there a better/easier way to create request objects rather than copying the entity classes, removing/adding annotations?

    - by Asaf David
    hey i have the following domain model: class Location { String name static hasMany = [locations:Location, persons:Person] } class Person { String name } so basically each location can hold a bunch of people + "sub-locations". what is the best way to recursively query for all persons under a location (including it's sub locations, and their sub locations, etc')?

  • Gridview SortExpression with 2 fields

    - by aron
    Hello, I have a GridView that get's its datasource from a complex object. So I'm doing the Sorting & Paging in the code behind. <asp:GridView ID="SystemsDetailList" runat="server" AllowSorting="true" AllowPaging="true" AutoGenerateColumns="False" ShowFooter="True" OnPageIndexChanging="gridView_PageIndexChanging" OnSorting="gridView_Sorting"> For an important title column I have a SortExpression with 2 fields: SortExpression="FunctionalAreaDisplayCode, EswbsDisplayCode" This in the code behind: protected void gridView_Sorting(object sender, GridViewSortEventArgs e) { BindSystemList(e.SortExpression, sortOrder); } public string sortOrder { get { if (ViewState["sortOrder"].ToString() == "desc") { ViewState["sortOrder"] = "asc"; } else { ViewState["sortOrder"] = "desc"; } return ViewState["sortOrder"].ToString(); } set { ViewState["sortOrder"] = value; } } For some reason it will keep "FunctionalAreaDisplayCode" always sorted ASC but the EswbsDisplayCode works fine as it flips between ASC and DESC correctly. and tips here? thanks!

  • How do I reference a pointer from a different class?

    - by Justagruvn
    First off, I despise singletons with a passion. Though I should probably be trying to use one, I just don't want to. I want to create a data class (that is instantiated only once by a view controller on loading), and then using a different class, message the crap out of that data instance until it is brimming with so much data, it smiles. So, how do I do that? I made a pointer to the instance of the data class when I instantiated it. I'm now over in a separate view controller, action occurs, and I want to update the initial data object. I think I need to reference that object by way of pointer, but I have no idea how to do that. Yes, I've set properties and getters and setters, which seem to work, but only in the initial view controller class. Peace Love applesauce.

  • Any way to stringify a variable id / symbol in Python?

    - by otz
    I'm wondering if it is possible at all in python to stringify variable id/symbol -- that is, a function that behaves as follows: >>> symbol = 'whatever' >>> symbol_name(symbol) 'symbol' Now, it is easy to do it on a function or a class (if it is a direct reference to the object): >>> def fn(): pass >>> fn.func_name 'fn' But I'm looking for a general method that works on all cases, even for indirect object references. I've thought of somehow using id(var), but no luck yet. Is there any way to do it?

  • Why do C# and Java require everything to be in a class?

    - by Javier Badia
    It seemed like this question should have been asked before, but searching found nothing. I've always wondered what's the point of making us put every bit of code inside a class or interface. I seem to remember that there were some advantages to requiring a main() function like C, but nothing for classes. Languages like Python are, in a way, even more object oriented than Java since they don't have primitives, but you can put code wherever you want. Is this some sort of "misinterpretation" of OOP? After all, you can write procedural code like you would in C and put it inside a class, but it won't be object oriented.

  • Why are Objective-C instance variables declared in an interface?

    - by Chase
    I'm just getting into Objective-C (Java is my primary OO language). Defining an object's instance variables in the interface instead of the class seems strange. I'm used to an interface being a public API definition with nothing besides method signatures (not counting constants here). Is there some reason that state is defined in an interface (even if it is private) and behaviour is defined in a class. It just seems odd that since objects are state+behavior that the definition would be split into two separate places. Is it a design benefit is some way? A pain in the rear issue that you are just forced to deal with in Objective-C? A non-issue, just different? Any background on why it's done this way? Or can you put object state in a class and I just haven't hit that part in my book yet?

  • c++ classes & lua

    - by anon
    I want to have C++ objects that I can read/write in both C++ & Lua. I have looked at: http://www.lua.org/pil/28.html However, I do not like that solution, since my objects have constructors & destructors (and they are important as I use RAII and these take care of reference counts). What I don't like in the PIL solution is that the object is allocated in Lua's heap. What i want instead, is to create hte C++ object on my own, and just have lua have a way to do get/set on them. Does anyone have a good tutorial/link on this? Tanks!

  • Retrieving Gtk::Widget's relative position: get_allocate() doesn't work

    - by a-v
    I need to retrieve the position of a Gtk::Widget relative to its parent, a Gtk::Table. Most sources (e.g. http://library.gnome.org/devel/gtk-faq/stable/x642.html) say that one needs to call Gtk::Widget::get_allocation(). However, the returned Gtk::Allocation object always contains x = -1, y = -1, width = 1, height = 1. I have to note that this happens before the Gtk::Table object is actually exposed and rendered. A call to show_all_children() or check_resize(), which I would expect to recalculate child widget geometry, doesn't help. What am I doing wrong? Thanks in advance.

  • Is there a way to have three way habtm associations in rails / activerecord?

    - by txwikinger
    Often three (or more) way associations are needed for habtm associations. For instance a permission model with roles. A particular area of functionality has many users which can access many areas. The permissions on the area are setup via roles (habtm) The user/roles association is also habtm The permissions (read, write, delete, etc) are habtm towards roles. How would that be best done with rails/activerecord?

  • Switching from php to python

    - by ts
    Hello I am trying to make a list of things which can be difficult/surprising to someone who is changing language from PHP to Python. so far i have rather short list: forget require / include, learn import (this was most difficult to me - to understand package - module - class - object hierarchy and its mapping to filesystem) you can't just upload file on server to have webpage (-mod_python, wsgi etc) learn the python way for use variable class names (new $class() vs import + getattr) / operator in python 2.x and all float-related horrors those were difficult to me, it takes few days before mind adapts a new paradigm after i found that there is few other areas which could be challenging for someone with (too) many years of php: everything is an object you have to live with exceptions array vs list, set, dictionary, tuple ... learn (effective) list comprehensions learn generators any other ideas / personal experiences ?

  • how to access a different movieclip within the flash in AS3

    - by Pieter888
    I've been trying to learn Action Script 3 the past few weeks, making tiny interactive games to learn the basics. I stumble upon a problem every now and then but most of the times google helps me out. But this problem has got me stuck so please help: The main stage contains two objects(movieclips), the player and a wall. The player has got his own code so when I drag in the player object I don't have to write any code into the main stage to be able to move the player. This all worked pretty well and I now wanted to add the wall so the player actually has something to bounce into. Now here is the problem, I want to check if the player touches the wall, I've done this before but that was when I used the main stage as my coding playground instead of putting the code in movieclips. How can I check if the player hits the wall within the movement code of the player object?

  • How do i generate random data with RSA?

    - by acidzombie24
    After loading my RSACryptoServiceProvider rsa object i would like to create a key for my AES object. Since i dont need to store the AES key (i only need it to decrypt on my prv side) i figure i dont need to store it and i can generate it with my public key. I thought doing rsa.Encrypt(byte[] with 4 hardcoded bytes); would generate the data i need. It turns out everytime i call this function even with the same data i get different results. So theres no way for me to recreate the AES key if its different everytime. How can i generate data with RSA in a way that i can recreate anytime i need?

  • Equivalent of c# 'as' command in c++?

    - by Sam
    In c# you can use as to convert a type or get null: Object o = Whatever(); String s = o as String; Is there a similar easy way to achieve this in c++? I'm using Visual Studio 2010, if thats important. [update] Remember, there is a very important difference between casting and using as. Casting (at least in c#) will throw an exception if the type does not match: Object o = null; String s = (String)o; // will crash.

  • What is going to be "the next Hype" ? [closed]

    - by kabado
    I know it's a very vague question, but maybe the answers could act like a poll about what could possibly be the next big event in computer science. A new language ? A new technology ? A new architecture ? A new business model ? Please provide details, what is it and why do you think it's going to rule the world.

  • How to tell Reflectively if an Attribute has a public Setter

    - by DrLazer
    Im saving an object model out to XML but when i load it back in I get exceptions when trying to use PropertyInfo.SetValue() because the property doesn't have a setter just a getter. I want to either not save out the properties that only have getters or figure out on load whether its valid for me to try and set a value or not. Anybody know how to do this Cheers

  • What's the best way to return something like a collection of `std::auto_ptr`s in C++03?

    - by Billy ONeal
    std::auto_ptr is not allowed to be stored in an STL container, such as std::vector. However, occasionally there are cases where I need to return a collection of polymorphic objects, and therefore I can't return a vector of objects (due to the slicing problem). I can use std::tr1::shared_ptr and stick those in the vector, but then I have to pay a high price of maintaining separate reference counts, and object that owns the actual memory (the container) no longer logically "owns" the objects because they can be copied out of it without regard to ownership. C++0x offers a perfect solution to this problem in the form of std::vector<std::unique_ptr<t>>, but I don't have access to C++0x. Some other notes: I don't have access to C++0x, but I do have TR1 available. I would like to avoid use of Boost (though it is available if there is no other option) I am aware of boost::ptr_container containers (i.e. boost::ptr_vector), but I would like to avoid this because it breaks the debugger (innards are stored in void *s which means it's difficult to view the object actually stored inside the container in the debugger)
