  • C# Array or Dictionary?

    - by Valentin
    Hi. I wanted to know is C# array has a constant access speed? I need to store 1000 items in static array, that will be initialized during server startup. This array will be used readonly, so there will be no changes to array. Should I use a simple C# array (new MyClass[]) or Dictionary instead. I am really new to C# and trying to understand how C# arrays access works. Can they be compared to c++ arrays by speed?

  • How do I create a ListBox In Ext-GWT ?

    - by Salvin Francis
    Plain and Simple, I want to use a Listbox in my project, The demo here: http://www.extjs.com/examples shows no answer, In fact, I really hate it when companies show-off their 'complex' widgets in this manner and fail to show the most basic of all widgets. For example, I discovered class SimpleComboBox over the net till then I assumed that we required a class to contain list store, etc...

  • Why should I use "Web 2.0"-style URLs?

    - by hydrapheetz
    In short, why use something like http://stackoverflow.com/badges/6/supporter instead of something "simpler" (and subjectively, at that) like http://stackoverflow.com/badges/6/. Even on my own site I've just been using /post/6/ to reference posts (by IDs, even though I still store a slug.) Instead of /post/6/small-rant-on-urls, and in some cases, they can get even more absurd, much more so than is really necessary.

  • Overriding iPhone shutter sound through SDK

    - by Suresh
    In my iPhone app, I am using the UIImagePickerController with source type UIImagePickerControllerSourceTypeCamera. When the user takes a picture, the phone plays the familiar camera shutter sound. How can I replace this with my own custom sound? I know it's possible because I've seen other apps from the App Store do it (e.g. Red Laser). Thanks in advance!

  • PL/SQL execption and Java programs

    - by edwards
    Hi Business logic is coded in pl/sql paackages procedures and functions. Java programs call pl/sql packages procedures and functions to do database work. Issue now is pl/sql programs store excpetions into Oracle tables whenever a execption is raised. How would my java programs get the execptions since the exception instead of being propogated from pl/sql to java is getting persisted to a oracle table.

    - by scootklein
    i will have multiple applications on the app store and 1 urban airship account to send push notifications to all of these devices. what i want to know is if each apple device has the same "push token" across all applications? this is more of a database architecture thing so that I don't duplicate a push token many times if one single device uses many of my apps if each apple device generates a unique push token for each application it has installed my architecture needs to change.

  • Suggestions for library to hash passwords in JAVA

    - by DutrowLLC
    What JAVA library should I be using to Hash passwords for storage in a database? I was hoping to just take the plain text password, add a random salt, then store the salt and the hashed password in the database. Then when a user wanted to log in, I could just take their submitted password, add the random salt from their account information, hash it and see if it equates to the stored hash password with their account information.

  • Using Time datatype in MySQL without seconds

    - by Alex
    I'm trying to store a 12/24hr (ie; 00:00) clock time in a MySQL database. At the moment I am using the time datatype. This works ok but it insists on adding the seconds to the column. So you enter 09:20 and it is stored as 09:20:00. Is there any way I can limit it in MySQL to just 00:00?

  • Read/Write versus Create/Read/Update/Delete permissions difference

    - by archmeta
    From a practical standpoint, is there any real-world difference between Read/Write permissions and Create/Read/Update/Delete permissions? It would seem that if a user had the ability to 'create', he should always have the ability to 'update' or 'delete'? If this is correct, then read/write should always be sufficient, and there is no need to store separate Create/Read/Update/Delete permissions? Are there any real-world use cases in which a user should be given permissions to create but not update, or update but not delete, etc...?

  • Sharepoint tools for document version control

    - by notnot
    Does anyone know of any tools for extending the functionality of Sharepoint's existing version control system for Office documents? It'd be great to be able to do branching/merging, or to store versions as "deltas" off the previous to cut down on storage used. Any suggestions at all would be helpful. Thanks in advance!

  • C++ game designing & polymorphism question

    - by Kotti
    Hi! I'm trying to implement some sort of 'just-for-me' game engine and the problem's plot goes the following way: Suppose I have some abstract interface for a renderable entity, e.g. IRenderable. And it's declared the following way: interface IRenderable { // (...) // Suppose that Backend is some abstract backend used // for rendering, and it's implementation is not important virtual void Render(Backend& backend) = 0; }; What I'm doing right now is something like declaring different classes like class Ball : public IRenderable { virtual void Render(Backend& backend) { // Rendering implementation, that is specific for // the Ball object // (...) } }; And then everything looks fine. I can easily do something like std::vector<IRenderable*> items, push some items like new Ball() in this vector and then make a call similiar to foreach (IRenderable* in items) { item->Render(backend); } Ok, I guess it is the 'polymorphic' way, but what if I want to have different types of objects in my game and an ability to manipulate their state, where every object can be manipulated via it's own interface? I could do something like struct GameState { Ball ball; Bonus bonus; // (...) }; and then easily change objects state via their own methods, like ball.Move(...) or bonus.Activate(...), where Move(...) is specific for only Ball and Activate(...) - for only Bonus instances. But in this case I lose the opportunity to write foreach IRenderable* simply because I store these balls and bonuses as instances of their derived, not base classes. And in this case the rendering procedure turns into a mess like ball.Render(backend); bonus.Render(backend); // (...) and it is bad because we actually lose our polymorphism this way (no actual need for making Render function virtual, etc. The other approach means invoking downcasting via dynamic_cast or something with typeid to determine the type of object you want to manipulate and this looks even worse to me and this also breaks this 'polymorphic' idea. So, my question is - is there some kind of (probably) alternative approach to what I want to do or can my current pattern be somehow modified so that I would actually store IRenderable* for my game objects (so that I can invoke virtual Render method on each of them) while preserving the ability to easily change the state of these objects? Maybe I'm doing something absolutely wrong from the beginning, if so, please point it out :) Thanks in advance!

  • adding a div with data()

    - by Dizzy Bryan High
    Hi people am generating a list of flash swfs, the information comes from an ajax call which returns a json object which i loop through to create the rows of data using my makeAppRow function. makeAppRow = function(myData){ var myStr = '<div class="fileEntry">' myStr = myStr +'<div class="appDate">'+dateFormat(myData.date_swf, "dS mmmm, yyyy, h:MM TT")+'</div>' myStr = myStr +'<div class="appName">'+myData.name_swf+'</div>' myStr = myStr +'<div class="appOptions" data>' myStr = myStr +'<div class="gotoAppBtn" data-options="'+myData+'">Open App</div>' myStr = myStr +'</div>' myStr = myStr +'</div>' $('#appData').append(myStr); } I need the json data to be attached to the gotoAppBtn so that when its clicked i can read in the data from the attached json object and use it in my click function, as you can see ive been trying to embed the data using the html5 data but i cant get it to work. <div class="gotoAppBtn" data-options="'+myData+'">Open App</div> i have a function so that when the button is clicked it loads in an swf. $('.gotoAppBtn').live('click', function(){ //alert('button clicked') var myData = $(this).data("options") alert('../userfiles/'+myData.id_ugp+'/'+myData.id_swf+'/'+myData.launchfile_swf+'') console.log(myData); var flashvars = {}; var params = {}; params.menu = "false"; params.quality = "best"; params.scale = "noscale"; var attributes = {}; attributes.id = "flashAppDisplay"; attributes.name = "flashAppDisplay"; swfobject.embedSWF( '../userfiles/'+myData.id_ugp+'/'+myData.id_swf+'/'+myData.launchfile_swf+'', 'flashAppDisplay', myData.width_swf, myData.height_swf, myData.version_swf ,"../FAVideo/expressInstall.swf", flashvars, params, attributes) }); but the data does not seem to be there, any pointers on where i am going wrong, or a better way to achive this???
