678,259 | 0 | How Does a Login system generally work with OOP? <p>Sorry if this is a badly formed question, but I'm trying to make my web applications (using PHP) more OO. *EDIT* I'm developing the Framework myself */EDIT* Everything is great so far, I've made a Front Controller system that taps into a MVC system. The FC figures out what page you want, loads the specific page Controller (*EDIT* which extends an abstract Controller Object */EDIT*), which gets anything it needs from Models, and then calls the appropriate View. Very basic.</p> <p>But now, I need to make an admin section (quasi-CMS). How does a login system fit into the grand scheme of things? Do you set controllers as needing a login? If so, how? What If you only want certain views of a controller requiring login?</p> <p>Thanks in advance.</p> |

1,740,297 | 0 | How do I build a DNS Query record in Erlang? <p>I am building a native Bonjour / Zeroconf library and need to build DNS query records to broadcast off to the other machines. I have tried looking thru the Erlang source code but as I am relatively new to Erlang it gets kind of dense down the bowels of all the inet_XXX.erl and .hrl files. I have a listener that works for receiving and parsing the DNS record payloads, I just can't figure out how to create the query records.

As I recall, they generate a salted hash so that the plain text values are never stored anywhere, but rather the hash and salt are. </p> <p>If you go into the django installation, and poke around for words like hash and salt, you should find it pretty quickly.

1,652,928 | 0 | <p>It sounds like what you want is a <a href="http://en.wikipedia.org/wiki/Finite-state_machine" rel="nofollow noreferrer">'Finite State Machine'</a> where using those cases you can activate different processes or 'states'. In C this is usually done with an array (matrix) of function pointers.</p> <p>So you essentially make an array and put the right function pointers at the right indicies and then you use your 'var' as an index to the right 'process' and then you call it. You can do this in most languages. That way different inputs to the machine activate different processes and bring it to different states. This is very useful for numerous applications; I myself use it all of the time in MCU development.</p> <p>Edit: Valya pointed out that I probably should show a basic model:</p> <pre><code>stateMachine[var1][var2](); // calls the right 'process' for input var1, var2 </code></pre> |

If malloc returns <code>NULL</code> there's probably a reason for it (out of memory for example). And you might throw yourself into an infinite loop.</p> <p>Furthermore, if you're running this on a Linux platform:</p> <blockquote> <p>By default, Linux follows an optimistic memory allocation strategy. This means that when malloc() returns non-NULL there is no guarantee that the memory really is available.</p> </blockquote> <p>That means that lets say calling malloc over and over again did happen to return something non-NULL, due to Linux's "optimistic" strategy, a non-NULL still doesn't guarantee you got anything that will work.</p> <p>I think this code is setting you up for a debugging nightmare.</p> |

27,533,223 | 0 | <p>Since you reported that it was running when <code>len(nextList) == 0</code>, this is probably because <code>nextList</code> (which isn't a list..) is an empty bytes object which isn't equal to an empty string object:</p> <pre><code>>>> b"" == "" False </code></pre> <p>and so the condition in your line</p> <pre><code>while nextList != "": </code></pre> <p>is never true, even when <code>nextList</code> is empty.

1,006,453 | 0 | <p>That is one way. It's nice and simple, but a bit messy. You could get rid of the storyboard and on each tick, increment a local value by the tick interval and use that to set your time. You would then only have one time piece.</p> <p>Or... A more elegant and re-usable way would be to create a helper class that is a DependencyObject. I would also just use a StoryBoard with a DoubleAnimation an bind the Storyboard.Target to an instance of the DoubleTextblockSetter. Set the storyboard Duration to your time and set the value to your time in seconds. Here is the DoublerBlockSetterCode.</p> <pre><code>public class DoubleTextBlockSetter : DependencyObject { private TextBlock textBlock { get; private set; } private IValueConverter converter { get; private set; } private object converterParameter { get; private set; } public DoubleTextBlockSetter( TextBlock textBlock, IValueConverter converter, object converterParameter) { this.textBlock = textBlock; this.converter = converter; this.converterParameter = converterParameter; } #region Value public static readonly DependencyProperty ValueProperty = DependencyProperty.Register( "Value", typeof(double), typeof(DoubleTextBlockSetter), new PropertyMetadata( new PropertyChangedCallback( DoubleTextBlockSetter.ValuePropertyChanged ) ) ); private static void ValuePropertyChanged( DependencyObject obj, DependencyPropertyChangedEventArgs args) { DoubleTextBlockSetter control = obj as DoubleTextBlockSetter; if (control != null) { control.OnValuePropertyChanged(); } } public double Value { get { return (double)this.GetValue(DoubleTextBlockSetter.ValueProperty); } set { base.SetValue(DoubleTextBlockSetter.ValueProperty, value); } } protected virtual void OnValuePropertyChanged() { this.textBlock.Text = this.converter.Convert( this.Value, typeof(string), this.converterParameter, CultureInfo.CurrentCulture) as string; } #endregion } </code></pre> <p>Then you might have a format converter:</p> <pre><code>public class TicksFormatConverter : IValueConverter { TimeSpanFormatProvider formatProvider = new TimeSpanFormatProvider(); public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { long numericValue = 0; if (value is int) { numericValue = (long)(int)value; } else if (value is long) { numericValue = (long)value; } else if (value is double) { numericValue = (long)(double)value; } else throw new ArgumentException("Expecting type of int, long, or double."); string formatterString = null; if (parameter != null) { formatterString = parameter.ToString(); } else { formatterString = "{0:H:m:ss}"; } TimeSpan timespan = new TimeSpan(numericValue); return string.Format(this.formatProvider, formatterString, timespan); } public object ConvertBack( object value, Type targetType, object parameter, CultureInfo culture) { throw new NotImplementedException(); } } </code></pre> <p>I almost forgot the TimespanFormatProvider. There is no format provider for timespan in Silverlight, so it appears.</p> <pre><code>public class TimeSpanFormatProvider : IFormatProvider, ICustomFormatter { public object GetFormat(Type formatType) { if (formatType != typeof(ICustomFormatter)) return null; return this; } public string Format(string format, object arg, IFormatProvider formatProvider) { string formattedString; if (arg is TimeSpan) { TimeSpan ts = (TimeSpan)arg; DateTime dt = DateTime.MinValue.Add(ts); if (ts < TimeSpan.FromDays(1)) { format = format.Replace("d.", ""); format = format.Replace("d", ""); } if (ts < TimeSpan.FromHours(1)) { format = format.Replace("H:", ""); format = format.Replace("H", ""); format = format.Replace("h:", ""); format = format.Replace("h", ""); } // Uncomment of you want to minutes to disappear below 60 seconds. //if (ts < TimeSpan.FromMinutes(1)) //{ // format = format.Replace("m:", ""); // format = format.Replace("m", ""); //} if (string.IsNullOrEmpty(format)) { formattedString = string.Empty; } else { formattedString = dt.ToString(format, formatProvider); } } else throw new ArgumentNullException(); return formattedString; } } </code></pre> <p>All that stuff is re-usable and should live in your tool box. I pulled it from mine. Then, of course, you wire it all together:</p> <pre><code>Storyboard sb = new Storyboard(); DoubleAnimation da = new DoubleAnimation(); sb.Children.Add(da); DoubleTextBlockSetter textBlockSetter = new DoubleTextBlockSetter( Your_TextBlock, new TicksFormatConverter(), "{0:m:ss}"); // DateTime format Storyboard.SetTarget(da, textBlockSetter); da.From = Your_RefreshInterval_Secs * TimeSpan.TicksPerSecond; da.Duration = new Duration( new TimeSpan( Your_RefreshInterval_Secs * TimeSpan.TicksPerSecond)); sb.begin(); </code></pre> <p>And that should do the trick. An it's only like a million lines of code. And we haven't even written Hello World just yet...;) I didn't compile that, but I did Copy and Paste the 3 classes directly from my library. I've used them quite a lot. It works great. I also use those classes for other things. The TickFormatConverter comes in handy when data binding. I also have one that does Seconds. Very useful. The DoubleTextblockSetter allows me to animate numbers, which is really fun. Especially when you apply different types of interpolation.</p> <p>Enjoy.</p> |

5,070,173 | 0 | <p>A little late reply here, but right now, in Texas, I've got my nephew digging a 60in X 16in X 4ft hole just outside my home office. Into it I'll be placing a 40ft copper tubing "radiator". This with be the "core" of a geothermal loop to cool my mac. Yeah, it's wildly watercooled because the mods cause me to exceed the TDP (it's a MacPro1,1) of the case, but even before that my office got uncomfortably hot. Now it just causes my computer to shut down when I try to encode video. Not good.</p> <p>In the UK you should be able to do the same (well, cool your room at least) with just a ground loop, a cheap pump, and a fan with more copper tubing coiled behind it. My project has ended up costing me quite a bit because of its complexity and mistakes make along the way, but a simple system to cool just the room should cost less than £150-200 and is definitely a DIY project you and your dad could do.</p> <p>One of of the biggest reasons to do this are the electricity (cooling) costs saved for me, literally several hundred $ per year. And it's "Green" cooling. But the biggest reason is for the amount of science I've learned in the past 3 months.</p> <p>Talk to your Dad about it.

It states that as of v7 the TCP tuning is stored in the client configuration file. So if you have enabled TCP Keepalive in the Windows registry, the v7 client will ignore it. The format and location of the file is described in <a href="http://publib.boulder.ibm.com/infocenter/wmqv7/v7r0/topic/com.ibm.mq.csqzaf.doc/cs13350_.htm" rel="nofollow noreferrer">WebSphere MQ client configuration file</a>.</p> <p>Of course for this to be the problem, there has to be a socket leak. You did not mention which version of WMQ V7 client you have but the Fix Pack README files do show a number of APARs related to socket leaks, failure to clean up after disconnects and so forth. None of these directly mention C# or .Net but there are enough problems around connection/disconnection issues to make it worth an upgrade.</p> <p>So first & easiest fix to attempt is to add TCP Keepalive to the client configuration file and see if it helps. Disable connection sharing while you are in there as well. It's not supposed to be a factor but then it's not supposed to leak sockets either. Can't hurt. Next is to apply <a href="http://www-01.ibm.com/support/docview.wss?rs=171&uid=swg27006037" rel="nofollow noreferrer">Fix Pack 7.0.1.2</a> (latest as of this writing) and see if that fixes the problem.

It is possible to disable UDP checksums in IPv4, either at the socket or OS level. Doing so would reduce the CPU overhead of processing each packet at both the sender and receiver.

22,029,815 | 0 | How to use the QT Jni class "QAndroidJniObject" <p>I'm a beginner of "QT for Android" and now I'm using it to develop a communication oftware based on mobile.I hava developed java functions that call android's api as a class in a .java document.In order to Simplify UI development,the UI is based on QT Widget program.Then I use the QT-JNI class "QAndroidJniObject" to call these java functions according to QT5.2 API document.Android resource file is stored in the directory:./android/src/com/comm/sipcall/SipCallSend.java.Since the less information in this regard,I developed the java and c++ program according to API document.But I encountered the following problems, and also hope to get answers: 1) The QT program is based on QT Widget.The java program needs to get the current application object Context in order to initialize java object.The c++ code I developed as following:</p> <pre><code>//c++: QPlatformNativeInterface *interface = QApplication::platformNativeInterface(); jobject activity = (jobject)interface->nativeResourceForIntegration("QtActivity"); QAndroidJniObject* at = new QAndroidJniObject(activity); QAndroidJniObject appctx = at->callObjectMethod("getApplicationContext","()Landroid/content/Context;"); //.pro： QT += core gui gui-private </code></pre> <p>Is this right?</p> <p>2) The java class contains a constructor function and three public functions:</p> <pre><code>java: package com.comm.sipcall; improt XXXX .... .... public class SipCallSend extends Activity { private Context context; // 接收QT的context public String sipToAddress = ""; public String sipDomain = ""; public String user_name = ""; public String pass_word = ""; public SipCallSend(){ Log.i("ddd","init"); sipToAddress = ""; sipDomain = ""; user_name = ""; pass_word = ""; } public void SetContext(Context cnt) { this.context = cnt; //Log.i("ccc",user_name); } public int Login(String domain,String username,String password){ .... sipDomain = domain; user_name = username; pass_word = password; ... return 0; } public int Call(String addrNum) { ... return 0; } } C++： QPlatformNativeInterface *interface = QApplication::platformNativeInterface(); jobject activity = (jobject)interface->nativeResourceForIntegration("QtActivity"); QAndroidJniObject* at = new QAndroidJniObject(activity); QAndroidJniObject appctx = at->callObjectMethod("getApplicationContext","()Landroid/content/Context;"); QAndroidJniObject* m_sipcall = new QAndroidJniObject("com/comm/sipcall/SipCallSend"); if (!m_sipcall->isValid()) return; m_sipcall->callMethod<void>("SetContext","(Landroid/content/Context;)V", appctx.object<jobject>()); QAndroidJniObject domain = QAndroidJniObject::fromString("10.3.56.54"); QAndroidJniObject username = QAndroidJniObject::fromString("1006"); QAndroidJniObject password = QAndroidJniObject::fromString("1234"); jint res = m_sipcall->callMethod<jint>("Login","(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)I", domain.object<jstring>(), username.object<jstring>(),password.object<jstring>()); if (res!=0) return; QAndroidJniObject addrNum = QAndroidJniObject::fromString("1018"); res = m_sipcall->callMethod<jint>("Call","(Ljava/lang/String;)I",addrNum.object<jstring>()); </code></pre> <p>The "new QAndroidJniObject" returns non-empty,but the the following functions connot execute,why?</p> <p>3) I have tried to make the Context from c++ as a parameter of constructor function,but I found the code not running,why?</p> <pre><code>java: public SipCallSend(Context cnt){ this.context = cnt; } C++: QAndroidJniObject m_sipcall("com/comm/sipcall/SipCallSend","(Landroid/content/Context;)V",appctx.object<jobject>()); </code></pre> <p>4) According to QT5.2 API document,QAndroidJniObject provides a method named "callObjectMethod":</p> <pre><code>QAndroidJniObject myJavaString; ==> "Hello, Java" QAndroidJniObject mySubstring = myJavaString.callObjectMethod("substring", "(II)Ljava/lang/String;" 7, 10); </code></pre> <p>But when I use it as following, the IDE prompts me the parameter are incorrect,why?</p> <pre><code>jint res = m_sipcall->callMethod<jint>("Login","(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)I", domain.object<jstring>(), username.object<jstring>(),password.object<jstring>()); </code></pre> <p>Thanks...</p> |
469,653 | 0 | <p>Static objects are destroyed in the reverse of the order in which they're constructed (e.g. the first-constructed object is destroyed last), and you can control the sequence in which static objects are constructed, by using the technique described in Item 47, "<strong>Ensure that global objects are initialized before they're used</strong>" in Meyers' book <em>Effective C++</em>.</p> <blockquote> <p>For example to specify in some way that I would like a certain object to be destroyed last, or at least after another static onject?</p> </blockquote> <p>Ensure that it's constructed before the other static object.</p> <blockquote> <p>How can I control the construction order? not all of the statics are in the same dll.</p> </blockquote> <p>I'll ignore (for simplicity) the fact that they're not in the same DLL.</p> <p>My paraphrase of Meyers' item 47 (which is 4 pages long) is as follows. Assuming that you global is defined in a header file like this ...</p> <pre><code>//GlobalA.h extern GlobalA globalA; //declare a global </code></pre> <p>... add some code to that include file like this ...</p> <pre><code>//GlobalA.h extern GlobalA globalA; //declare a global class InitA { static int refCount; public: InitA(); ~InitA(); }; static InitA initA; </code></pre> <p>The effect of this will be that any file which includes GlobalA.h (for example, your GlobalB.cpp source file which defines your second global variable) will define a static instance of the InitA class, which will be constructed before anything else in that source file (e.g. before your second global variable).</p> <p>This InitA class has a static reference counter. When the first InitA instance is constructed, which is now guaranteed to be before your GlobalB instance is constructed, the InitA constructor can do whatever it has to do to ensure that the globalA instance is initialized.</p> |

12,427,493 | 0 | Programmatically check for a change in a class in C# <p>Is there a way to check for the size of a class in C#?</p> <p>My reason for asking is:</p> <p>I have a routine that stores a class's data in a file, and a different routine that loads this object (class) from that same file. Each attribute is stored in a specific order, and if you change this class you have to be reminded of these export/import routines needs changing.</p> <p>An example in C++ (no matter how clumsy or bad programming this might be) would be the following:</p> <pre><code>#define PERSON_CLASS_SIZE 8 class Person { char *firstName; } </code></pre> <p>...</p> <pre><code>bool ExportPerson(Person p) { if (sizeof(Person) != PERSON_CLASS_SIZE ) { CatastrophicAlert("You have changed the Person class and not fixed this export routine!") } } </code></pre> <p></p> <p>Thus before compiletime you need to know the size of Person, and modify export/import routines with this size accordingly.</p> <p>Is there a way to do something similar to this in C#, or are there other ways of "making sure" a different developer changes import/export routines if he changes a class.</p> <p>...

4,757,835 | 0 | <p>A bit late, but maybe it will still help you or someone else looking for this, the messages are themed in <a href="http://api.drupal.org/api/drupal/includes--theme.inc/function/theme_status_messages/6" rel="nofollow">theme_status_messages()</a> but you don't have any context about them at this point. However...</p> <p>Form errors are added through <a href="http://api.drupal.org/api/drupal/includes--form.inc/function/form_set_error/6" rel="nofollow">form_set_error()</a>, which stores them in an static array according to the form field name, you can access that through <a href="http://api.drupal.org/api/drupal/includes--form.inc/function/form_get_errors/6" rel="nofollow">form_get_errors()</a>.</p> <p>Now, you can load these errors and then look up the error messages in that error array and use the key as the id.</p> |
35,207,148 | 0 | <p><strong>For MVC6</strong>, You need to decorate the controllers with <code>Area</code> attribute. if you do not prefer to add this to individual controllers, you may simply create a base call which has Area decoration and inherit your other controllers from that.</p> <pre><code>[Area("Admin")] public class AdminArea : Controller { } public class OrdersController : AdminArea { public IActionResult Index() { return View(); } } public class ProductsController : AdminArea { public IActionResult Index() { return View(); } } </code></pre> <p><strong>MVC 5 and below</strong></p> <p>You do not need to put that attribute on your controller name, You can simply specify the area name in the area route registration.</p> <pre><code>public override void RegisterArea(AreaRegistrationContext context) { context.MapRoute( "Admin_default", "Admin/{controller}/{action}/{id}", new { action = "Index", controller= "YourDefaultCtrl", id = UrlParameter.Optional } ); } </code></pre> |
27,493,867 | 0 | <p>At first I thought you needed to include <code>ob_end_clean</code> like:</p> <pre><code>ob_start(); call_user_func( 'test', $args ); $ret_func = ob_get_clean(); $data = preg_replace( $re, $ret_func, $data); ob_end_clean(); </code></pre> <p>But then I ran a basic test myself doing this:</p> <pre><code><?php $i = 0; for($i=0; $i<10; $i++) { ob_start(); test(); $ret_func = ob_get_clean(); echo '<p>' . $ret_func . '</p>'; ob_end_clean(); //tried with this commented out as well echo '<p>' . $ret_func . '</p>'; } function test() { echo rand(0,100); } ?> </code></pre> <p>And it made no difference if I included <code>ob_end_clean</code> or not. So your problem is probably actually how you are rebuilding the <code>args</code> array in each iteration of the loop.</p> |
