• How can I login in a website with Pyhon?

• C# myths about best practices?

  - by TheMachineCharmer

  My colleague keeps telling me of the things listed in comments. I am confused. Can somebody please demystify these things for me? class Bar { private int _a; public int A { get { return _a; } set { _a = value; } } private Foo _objfoo; public Foo OFoo { get { return _objfoo; } set { _objfoo = value; } } public Bar(int a, Foo foo) { // this is a bad idea A = a; OFoo = foo; } // MYTHS private void Method() { this.A //1 - this._a //2 - use this when inside the class e.g. if(this._a == 2) A //3 - use this outside the class e.g. barObj.A _a //4 - // Not using this.xxx creates threading issues. } } class Foo { // implementation }

• Android WebViewClient problem

  - by deSelby

  I've defined a private class that extends WebViewClient and set my WebView's client to an instance of that class (webView01.setWebViewClient(new Callback());). The class definition is as follows: private class Callback extends WebViewClient { public void onLoadResource (WebView view, String url) { } public void onPageStarted (WebView view, String url, Bitmap favicon) { } public void onPageFinished (WebView view, String url) { Animation anim = AnimationUtils.loadAnimation(MyNews.this, R.anim.webviewanim); view.startAnimation(anim); } public void onReceivedError (WebView view, int errorCode, String description, String failingUrl) { } public boolean shouldOverrideUrlLoading (WebView view, String url) { Log.e("loading url", url); return false; } } My problem is that onPageFinished is definitely getting called, but shouldOverrideUrlLoading is never being called. What am I doing wrong here?

• [C++] Multiple inclusion in multiple files

  - by Amumu

  Hi everyone, I am making a small game. In BattleRecord.h: #ifndef _CHARACTER_H_ #define _CHARACTER_H_ #include "Character.h" #endif class BattleRecord { public: Character Attacker; Character Defender; Status status; int DamageDealt; int GoldEarned; int ExpGained; }; In Character.h: #ifndef _EQUIPMENT_H_ #define _EQUIPMENT_H_ #include "Equipment.h" #endif class BattleRecord; class Character { BattleRecord AttackEnemy(Character &Enemy); } In BattleRecord.h: #ifndef _CHARACTER_H_ #define _CHARACTEr_H_ #include "Character.h" #endif #ifndef _BATLE_RECORD_H_ #define _BATLE_RECORD_H_ #include "BattleRecord.h" #endif class GUI { public: //GUI Methods, and two of these: void ViewStats(Character &Player); void Report(BattleRecord Record) } The problem here is, my Character.h and BattleRecord.h need to include each other, and this definitely will cause multiple redefinition problem. Therefore, I used forward declaration in Character.h by adding: class BattleRecord; The problem is sovled. But then, the GUI.h needs BattleRecord.h again for reporting the battle, so I have to include BattleRecord.h into the GUI.h. I also have to include the Character.h in order to pass into the ViewStat function. I got error and stuck with this up to this piont.

• Null Inner Bean with Spring IoC

  - by bruno conde

  Hi all. I have a singleton bean definition like this: <bean id="exampleBean" class="com.examples.ExampleBean"> <property name="exampleBean2"> <bean class="com.examples.ExampleBean2" /> </property> </bean> where ExampleBean could be: public class ExampleBean { private ExampleBean2 exampleBean2; public ExampleBean() { } public ExampleBean2 getExampleBean2() { return exampleBean2; } public void setExampleBean2(ExampleBean2 exampleBean2) { this.exampleBean2 = exampleBean2; } } The problem is that, in certain conditions, the com.examples.ExampleBean2 class might not exist at runtime witch will cause an error when the IoC tries to instantiate exampleBean. What I need is to ignore this error from IoC and allow the exampleBean to be created but leaving the exampleBean2 property null. So the question is: is this possible in any way? Thanks for all your help.

• memcache is not storing data accross requests

  - by morpheous

  I am new to using memcache, so I may be doing something wrong. I have written a wrapper class around memcache. The wrapper class has only static methods, so is a quasi singleton. The class looks something like this: class myCache { private static $memcache = null; private static $initialized = false; public static function init() { if (self::$initialized) return; self::$memcache = new Memcache(); if (self::configure()) //connects to daemon { self::store('foo', 'bar'); } else throw ConnectionError('I barfed'); } public static function store($key, $data, $flag=MEMCACHE_COMPRESSED, $timeout=86400) { if (self::$memcache->get($key)!== false) return self::$memcache->replace($key, $data, $flag, $timeout); return self::$memcache->set($key, $data, $flag, $timeout); } public static function fetch($key) { return self::$memcache->get($key); } } //in my index.php file, I use the class like this require_once('myCache.php'); myCache::init(); echo 'Stored value is: '. myCache::fetch('foo'); The problem is that the myCache::init() method is being executed in full everytime a page is requested. I then remembered that static variables do not maintain state accross page requests. So I decided instead, to store the flag that indicates whether the server contains the start up data (for our purposes, the variable 'foo', with value 'bar') in memcache itself. Once the status flag is stored in memcache itself, It solves the problem of the initialisation data being loaded for every page request (which quite frankly, defeats the purpose of memcache). However, having solved that problem, when I come to fetch the data in memcache, it is empty. I dont understand whats going on. Can anyone clarify how I can store my data once and retrieve it accross page requests? BTW, (just to clarify), the get/set is working correctly, and if I allow memcache to load the initialisation data for each page request, (which is silly), then the data is available in memcache.

• How can I find all attributes with single quotes in a Sublime Text 2 document and replace with double quotes?

I'm working in some HTML docs that have single quotes around all attribute values through the docs, like this: <div class='classone classtwo'> I'd love to be able to do a find-and-replace in each doc and replace with double quotes, like this: <div class="classone classtwo"> Many elements in the document will have multiple attributes: <div class='classone classtwo' data-scripts='lazyload'> And some will have the correct double quotes: <div class='classone classtwo' data-scripts="lazyload"> What's the best way to replace all single quotes wrapping values with double?

• PHP + MySQL - Match first letter of directory

  - by user1822825

  Let's say I have a class table. In the class table, there are many students with their pictures. In the first registration, I've registered the class and students with pictures. The pictures were put into a directory like classid_classname. Then, I change the class name. Now, I'm adding the student's picture. Now, the new picture can't be recognized because the class name has changed. The pic url will be set as classid_class(new)name. How can I match the first letter of the directory? This is my update code : $classID= $_POST["classID"]; $className= $_POST["className"]; $p1 = $_FILES['p1']['name']; $p2 = $_FILES['p2']['name']; $p3 = $_FILES['p3']['name']; $direct = $_POST["className"]; $direct = strtolower($direct); $direct = str_replace(' ', '_', $direct); $tfish = $classID."_".$direct; //the directory variable will have new name because it can't be fetched if the directory has been changed many times// $file = "slider_imagesClass/".$tfish."/"; $url = "/".$tfish."/"; How can I make the variable to match the first letter of the directory because the classID will not change? Thank you. Really appreciate your help :D

• Ninject giving NullReferenceException

  - by Iceman

  I'm using asp.net MVC 2 and Ninject 2. The setup is very simple. Controller calls service that calls repository. In my controller I use inject to instantiate the service classes with no problem. But the service classes don't instantiate the repositories, giving me NullReferenceException. public class BaseController : Controller { [Inject] public IRoundService roundService { get; set; } } This works. But then this does not... public class BaseService { [Inject] public IRoundRepository roundRepository { get; set; } } Giving a NullReferenceException, when I try to use the roundRepository in my RoundService class. IList<Round> rounds = roundRepository.GetRounds( ); Module classes... public class ServiceModule : NinjectModule { public override void Load( ) { Bind( ).To( ).InRequestScope( ); } } public class RepositoryModule : NinjectModule { public override void Load( ) { Bind<IRoundRepository>( ).To<RoundRepository>( ).InRequestScope( ); } } In global.axax.cs protected override IKernel CreateKernel( ) { return new StandardKernel( new ServiceModule( ), new RepositoryModule( ) ); }

• jquery clone only once

  - by tsiger

  I have a series of divs like this: <div id="available-posts"> <div class="post" id="unique_id"> <a href="#" class="addme">Add</a> Some text </div> <div class="post" id="unique_id"> <a href="#" class="addme">Add</a> Some text </div> </div> The unique_id is a different number for each of the divs. Now i have a new empty div like this <div class="related-posts"></div> And i clone items in there. The thing is that i want to check if an item is already cloned. If it is i want to stop it from being cloned again. This is how i clone items: // clone it $('.addme').live('click', function() { $(this).parents('div.thepost').clone().fadeIn('normal').appendTo('#related-posts').find('a.addme').html('Remove').removeClass('addme').addClass('removeme'); return false; }); // remove it $('.removeme').live('click', function() { $(this).parents('div.thepost').fadeOut('normal', function() {$(this).remove(); }); return false; }); In other words i want the cloned list to contain only unique items. Not for example 2 clones of the same post. *edit: i am using live coz the first list (available posts) is populated through an AJAX call.

• Python and the self parameter

  - by Svend

  I'm having some issues with the self parameter, and some seemingly inconsistent behavior in Python is annoying me, so I figure I better ask some people in the know. I have a class, Foo. This class will have a bunch of methods, m1, through mN. For some of these, I will use a standard definition, like in the case of m1 below. But for others, it's more convinient to just assign the method name directly, like I've done with m2 and m3. import os def myfun(x, y): return x + y class Foo(): def m1(self, y, z): return y + z + 42 m2 = os.access m3 = myfun f = Foo() print f.m1(1, 2) print f.m2("/", os.R_OK) print f.m3(3, 4) Now, I know that os.access does not take a self parameter (seemingly). And it still has no issues with this type of assignment. However, I cannot do the same for my own modules (imagine myfun defined off in mymodule.myfun). Running the above code yields the following output: 3 True Traceback (most recent call last): File "foo.py", line 16, in <module> print f.m3(3, 4) TypeError: myfun() takes exactly 2 arguments (3 given) The problem is that, due to the framework I work in, I cannot avoid having a class Foo at least. But I'd like to avoid having my mymodule stuff in a dummy class. In order to do this, I need to do something ala def m3(self,a1, a2): return mymodule.myfun(a1,a2) Which is hugely redundant when you have like 20 of them. So, the question is, either how do I do this in a totally different and obviously much smarter way, or how can I make my own modules behave like the built-in ones, so it does not complain about receiving 1 argument too many.

• How to use a CTabCtrl in a MFC dialog based application ?

  - by shan23

  I need to do something which i expected to be was simple - create a tab control which has 2 tabs, implying 2 modes of operation for my app. When user clicks on Tab1, he'll be presented with some buttons and textboxes, and when he clicks Tab2, some other input method. I noticed that there was a CTabCtrl class thats used in MFC to add tabs. However, once I added the tab ctrl using the UI designer, I couldn't specify how many tabs there'll be using property window. Searching on the net, I found some examples but all of them required you to derive from CtabCtrl , create 2 or more child dialogs etc and to write your own custom class. My question is, since I want to do something so basic, why couldn't I do it using the familiar Add Event handler/Add member variable wizard and then handle everything else inside my app's class ? Surely, the default CTabCtrl class can do something useful without needing to derive from it ?
