    Is there anyone who has a good (basic) UML class diagram to get me started on an object oriented CMS? I want to start using OOP in PHP but can't seem to find a good starting point.

  • Boo: Explicitly specifying the type of a hash

    - by Kiv
    I am new to Boo, and trying to figure out how to declare the type of a hash. When I do: myHash = {} myHash[key] = value (later) myHash[key].method() the compiler complains that "method is not a member of object". I gather that it doesn't know what type the value in the hash is. Is there any way I can declare to the compiler what type the keys and values of the hash are so that it won't complain?

  • how to implement IOC without a global static service?

    - by Michel
    Hi, we want to use Unity for IOC. All i've seen is the implementation that there is one global static service which holds a reference to the Unity container, which registers all interface/class combinations and every class asks that object: give me an implementation for Ithis or IThat. Frequently i see a response that this pattern is not good because it leads to a dependency from ALL classes to this service. But what i don't see often, is: what is the alternative way? Michel

  • Save simple data in Magento's DB w/o Model

    - by Joseph Mastey
    I'm looking to save some data in the Magento database without hassling with creating a new EAV object (or even a DB table if I can avoid it). Is there any place that you all know about that Magento will let you store serialized data? If it matters, the data is a serialized set of SKUs that I need to retrieve. I know that I could create a new model, or possibly even create an attribute as a flag on each product, but those are both really overkill for my purposes. Thanks, Joe

  • Ninject and DataContext disposal

    - by Bas
    I'm using Ninject to retrieve my DataContext from the kernel and I was wondering if Ninject automatically disposes the DataContext, or how he handles the dispose() behaviour. From own experiences I know disposing the datacontext is pretty important and that whenever you create a direct object of the DataContext (as in: new DataContext()) you should use a using() block. My question thus is: When im retrieving my DataContext from the kernel, should I still have to use a using() block? Or does Ninject fix this for me?

    I've just updated to the AJAX Control Toolkit 3.5, changed the ScriptManager to the ToolkitScriptManager in my master page and now the following javascript error occurs when an Edit button is clicked: "Object doesn't support this property or method" The line of code cuasing the error is: this._destroyTree(updatePanelElement); Any initial ideas before I post masses of code?

  • Undefined Behavior and Sequence Points Reloaded

    - by Nawaz
    Consider this topic a sequel of the following topic: Previous Installment Undefined Behavior and Sequence Points Let's revisit this funny and convoluted expression (the italicized phrases are taken from the above topic *smile* ): i += ++i; We say this invokes undefined-behavior. I presume that when say this, we implicitly assume that type of i is one of built-in types. So my question is: what if the type of i is a user-defined type? Say it's type is Index which is defined later in this post (see below). Would it still invoke undefined-behavior? If yes, why? Is it not equivalent to writing i.operator+=(i.operator ++()); or even syntactically simpler i.add(i.inc());? Or, do they too invoke undefined-behavior? If no, why not? After all, the object i gets modified twice between consecutive sequence points. Please recall the rule of thumb : an expression can modify an object's value only once between consecutive "sequence points. And if i += ++i is an expression, then it must invoke undefined-behavior. If so, then it's equivalents i.operator+=(i.operator ++()); and i.add(i.inc()); must also invoke undefined-behavior which seems to be untrue! (as far as I understand) Or, i += ++i is not an expression to begin with? If so, then what is it and what is the definition of expression? If it's an expression, and at the same time, it's behavior is also well-defined, then it implies that number of sequence points associated with an expression somehow depends on the type of operands involved in the expression. Am I correct (even partly)? By the way, how about this expression? a[++i] = i; //taken from the previous topic. but here type of `i` is Index. class Index { int state; public: Index(int s) : state(s) {} Index& operator++() { state++; return *this; } Index& operator+=(const Index & index) { state+= index.state; return *this; } operator int() { return state; } Index & add(const Index & index) { state += index.state; return *this; } Index & inc() { state++; return *this; } };

  • Winforms: calling entry form function from a different class

    - by samy
    I'm kinda new to programming and got a question on what is a good practice. I created a class that represents a ball and it has a function Jump() that use 2 timers and get the ball up and down. I know that in Winforms you got to call Invalidate() every time you want to repaint the screen, or part of it. I didn't find a good way to do that, so I reference the form in my class, and called Invalidate() inside my ball class every time I need to repaint to ball movement. (this works but I got a feeling that this is not a good practice) Here is the class I created: public class Ball { public Form1 parent;//----> here is the reference to the form public Rectangle ball; Size size; public Point p; Timer timerBallGoUp = new Timer(); Timer timerBallGDown = new Timer(); public int ballY; public Ball(Size _size, Point _p) { size = _size; p = _p; ball = new Rectangle(p, size); } public void Jump() { ballY = p.Y; timerBallGDown.Elapsed += ballGoDown; timerBallGDown.Interval = 50; timerBallGoUp.Elapsed += ballGoUp; timerBallGoUp.Interval = 50; timerBallGoUp.Start(); } private void ballGoUp(object obj,ElapsedEventArgs e) { p.Y++; ball.Location = new Point(ball.Location.X, p.Y); if (p.Y >= ballY + 50) { timerBallGoUp.Stop(); timerBallGDown.Start(); } parent.Invalidate(); // here i call parent.Invalidate() 1 } private void ballGoDown(object obj, ElapsedEventArgs e) { p.Y--; ball.Location = new Point(ball.Location.X, p.Y); if (p.Y <= ballY) { timerBallGDown.Stop(); timerBallGoUp.Start(); } parent.Invalidate(); // here i call parent.Invalidate() 2 } } I'm wondring if there is a better way to do that? (sorry for my english)

  • GridLayout with single column

    - by Albinoswordfish
    Right now I'm trying to use a GridLayout with only a single column. However I'm having a problem where I don't want the object, in this case a JButton, to be stretched the entire width of the JPanel that it's on. Is there a way to decrease the width of the JButton so that it does not stretch the entire width of the JPanel. I've tried using setPreferredSize and setSize with no results. Is this just the way GridLayout works or is there something I'm missing?

  • How to merge jquery autocomplete and fcbkListSelection functionality?

    - by Ben
    Initial caveat: I am a newbie to jquery and javascript. I started using the autocomplete jquery plugin recently from bassistance.de. Yesterday, I found the fcbkListSelection plugin (http://www.emposha.com/javascript/fcbklistselection-like-facebook-friends-selector.html) and am using it to include a selector in my application. What I now want to do is to merge the 2 pieces of functionality since there are lots of items in my selector list. To be more specific, I want to put a "Filter by Name" text box above the facebook list selection object in my html. When the user types a few characters into the "Filter by Name" text box, I want the items in the Facebook list selector to only show the items that contain the typed characters -- kind of like what autocomplete does already, but rather than the results showing below the text input box, I want them to dynamically update the facebook list object. Is this possible and relatively straightforward? If so, can somebody please describe how to do it? If not, is there an easier way to approach this? Thanks! OK, to Spencer Ruport's comment, I guess I may have a more specific question already. Below is the current Javascript in my HTML file (angle brackets represent Django tags). #suggest1 and #fcbklist both do their separate pieces, but how do I get them to talk to each other? Do I need to further write javascript in my HTML file, or do I need to customize the guts of the plugins' .js? Does this help elaborate? $(document).ready(function() { var names = []; var count = 0; {% for a, b, c in friends_for_picker %} names[count] = "{{ b }}"; count = count+1; {% endfor %} function findValueCallback(event, data, formatted) { $("<li>").html( !data ? "No match!" : "Selected: " + formatted).appendTo("#result"); } function formatItem(row) { return row[0] + " (<strong>id: " + row[1] + "</strong>)"; } function formatResult(row) { return row[0].replace(/(<.+?>)/gi, ''); } $("#suggest1").autocomplete(names, { multiple: true, mustMatch: false, autoFill: true, matchContains: true, }); //id(ul id),width,height(element height),row(elements in row) $.fcbkListSelection("#fcbklist","575","50","4"); });

  • add text to the choice_label of ChoiceField in Django

    - by pablo
    The ChoiceField creates a select html element and the options show the choice_label which is the _unicode_ of each model object. How can I change the text of the choice_label without modifying _unicode_ ? I have a Product model and I want to show in the options text the product name + price + link to edit. I've searched in fields.py and widgets.py but couldn't find what needed to be changed. Thanks

  • Javascript static method intheritance

    - by Matteo Pagliazzi
    I want to create a javascript class/object that allow me to have various method: Model class Model.all() » static method Model.find() » static method Model delete() » instance method Model save() » instance method Model.create() » static that returns a new Model instance For static method I can define them using: Model.staticMethod(){ method } while for instance method is better to use: function Model(){ this.instanceMethod = function(){} } and then create a new instance or using prototype? var m = function Model(){ } m.prototype.method() = function(){ } Now let's say that I want to create a new class based on Model, how to inherit not only its prototypes but also its static methods?

  • QT vs. Net - REAL comparisons for R.A.D. projects

    - by Pirate for Profit
    Man in all these Qt vs. .NET discussions 90% these people argue about the dumbest crap. Trying to get a real comparison chart here, because I know a little about both frameworks but I don't know everything. I believe Qt and .NET both have strengths and weaknesses. This is to make a comparison that highlights these so people can make more informed decisions before embarking on a project, in the spirit of R.A.D. Event Handling In Qt the event handling system is very simple. You just emit signals when something cool happens and then catch them in slots. ie. // run some calculations, then emit valueChanged(30, false, 20.2); and then catching it, any object can make a slot to recieve that message easily void MyObj::valueChanged(int percent, bool ok, float timeRemaining). It's easy to "block" an event or "disconnect" when needed, and works seamlessly across threads... once you get the hang of it, it just seems a lot more natural and intuitive than the way the .NET event handling is set up (you know, void valueChanged(object sender, CustomEventArgs e). And I'm not just talking about syntax, because in the end the .NET anonymous delegates are the bomb. I'm also talking about in more than just reflection (because, yes, .NET obviously has much stronger reflection capabilities). I'm talking about in the way the system feels to a human being. Qt wins hands down for the simplest yet still flexible event handling system ever i m o. Plugins and such I do love some of the ease of C# compared to C++, as well as .NET's assembly architecture, even though it leads to a bunch of .dll's (there's ways to combine everything into a single exe though). That is a big bonus for modular projects, which are a PITA to import stuff in C++ as far as RAD is concerned. Database Ease of Doing Crap Also what about datasets and database manipulations. I think .net wins here but I'm not sure. Threading/Conccurency How do you guys think of the threading? In .NET, all I've ever done is make like a list of master worker threads with locks. I like QConcurrentFramework, you don't worry about locks or anything, and with the ease of the signal slot system across threads it's nice to get notified about the progress of things. QConcurrent is the simplest threading mechanism I've ever played with. Memory Usage Also what do you think of the overall memory usage comparison. Is the .NET garbage collector pretty on the ball and quick compared to the instantaneous nature of native memory management? Or does it just let programs leak up a storm and lag the computer then clean it up when it's about to really lag? Doesn't the just-in-time compiler make native code that is pretty good, like and that only happens the first time the program is run? However, I am a n00b who doesn't know what I'm talking about, please school me on the subject.

I cannot find any documentation to convert the transmitted string to a Public key that can be used to encrypt Strings. I also want the J2me to verify signed strings from the server. I want to then send the encrypted strings back to the server.

  • C# Spell checker Problem

    I've incorporated spell check into my win forms C# project. This is my code. public void CheckSpelling() { try { // declare local variables to track error count // and information int SpellingErrors = 0; string ErrorCountMessage = string.Empty; // create an instance of a word application Microsoft.Office.Interop.Word.Application WordApp = new Microsoft.Office.Interop.Word.Application(); // hide the MS Word document during the spellcheck //WordApp.WindowState = WdWindowState.wdWindowStateMinimize; // check for zero length content in text area if (this.Text.Length > 0) { WordApp.Visible = false; // create an instance of a word document _Document WordDoc = WordApp.Documents.Add(ref emptyItem, ref emptyItem, ref emptyItem, ref oFalse); // load the content written into the word doc WordDoc.Words.First.InsertBefore(this.Text); // collect errors form new temporary document set to contain // the content of this control Microsoft.Office.Interop.Word.ProofreadingErrors docErrors = WordDoc.SpellingErrors; SpellingErrors = docErrors.Count; // execute spell check; assumes no custom dictionaries WordDoc.CheckSpelling(ref oNothing, ref oIgnoreUpperCase, ref oAlwaysSuggest, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing); // format a string to contain a report of the errors detected ErrorCountMessage = "Spell check complete; errors detected: " + SpellingErrors; // return corrected text to control's text area object first = 0; object last = WordDoc.Characters.Count - 1; this.Text = WordDoc.Range(ref first, ref last).Text; } else { // if nothing was typed into the control, abort and inform user ErrorCountMessage = "Unable to spell check an empty text box."; } WordApp.Quit(ref oFalse, ref emptyItem, ref emptyItem); System.Runtime.InteropServices.Marshal.ReleaseComObject(WordApp); // return report on errors corrected // - could either display from the control or change this to // - return a string which the caller could use as desired. // MessageBox.Show(ErrorCountMessage, "Finished Spelling Check"); } catch (Exception e) { MessageBox.Show(e.ToString()); } } The spell checker works well, the only problem is when I try to move the spell checker the main form blurs up for some reason. Also when I close the spell checker the main form is back to normal. It seems like it is opening up Microsoft word then hiding the window, only allowing the spell checker to be seen. Please help.
