  • Class not overwriting with addClass

    - by scatteredbomb
    I'm using jQuery's addClass to add a class to an tab so when clicked it'll change the class so it's obvious the tab is highlighted. My HTML <div id="mainNav"> <ul> <li id="LinktheBand" onclick="nav('theBand')">The Band</li> <li id="linkTheMusic" onclick="nav('theMusic')">The Music</li> My CSS #mainNav li { float:left; margin-right:5px; color:white; font-family:Tahoma; font-weight:bold; padding: 10px 8px 0px 8px; background:url('../images/transparent-65.png'); height:40px; height: 25px !important; border:1px solid #000; } #mainNav li:hover { float:left; margin-right:5px; color:white; font-family:Tahoma; font-weight:bold; padding: 10px 8px 0px 8px; background: #660000; height:40px; height: 25px !important; border:1px solid #660000; } .mainNavSelected { float:left; margin-right:5px; color:white; font-family:Tahoma; font-weight:bold; padding: 10px 8px 0px 8px; background: #660000; height:40px; height: 25px !important; border:1px solid #660000; } My Javascript function nav(a) { $('#'+a).show(); $('#Link'+a).addClass('mainNavSelected'); } This works properly, I check firebug and can see the class="mainNavSelected" is added, but the list element doesn't take any properties of the new class. Firebug lists all the class items for mainNavSelected, but has them all crossed out. What am i missing to replace the class of this element?

  • Change storyboard UIImageView to own class with backgroundcolor

    - by Thomas
    I want to draw the background image on my own, so I decided to implement a UIImageView class and connect it in the Storyboard. As first task I just want to set the backgroundcolor of the image on my own, but it's never shown. Image just stays blank. That's the class: class FirstBackgroundImage : UIImageView { required init(coder aDecoder: NSCoder) { super.init(coder: aDecoder) self.backgroundColor = UIColor.redColor() } override init() { super.init() self.backgroundColor = UIColor.redColor() } override required init(image: UIImage!) { super.init(image: image) self.backgroundColor = UIColor.redColor() } } That's how i connected it:

  • How to add a reference to my Web Service Proxy from a Custom Class

    - by coffeeaddict
    I'm creating a custom class to abstract out some of the repeated SOAP header work. I want to reference a Web Service Reference I just created in my custom class so I can create an instance of it. How do I reference it? Notice I said I am trying to reference a Web Service "reference" (right click in VS and I added a "Web Service Reference" not a "Web Service"). So I'm trying to create an instance of that Proxy class that was created in MyCustomClass.cs

  • C++ explicit template specialization of templated constructor of templated class

    - by Victor Liu
    I have a class like template <class T> struct A{ template <class U> A(U u); }; I would like to write an explicit specialization of this for a declaration like A<int>::A(float); In the following test code, if I comment out the specialization, it compiles with g++. Otherwise, it says I have the wrong number of template parameters: #include <iostream> template <class T> struct A{ template <class U> A(T t, U *u){ *u += U(t); } }; template <> template <> A<int>::A<int,float>(int t, float *u){ *u += U(2*t); } int main(){ float f = 0; int i = 1; A<int>(i, &f); std::cout << f << std::endl; return 0; }

  • PHP 'instanceof' failing with class constant

    - by Nathan Loding
    I'm working on a framework that I'm trying to type as strongly as I possibly can. (I'm working within PHP and taking some of the ideas that I like from C# and trying to utilize them within this framework.) I'm creating a Collection class that is a collection of domain entities/objects. It's kinda modeled after the List<T> object in .Net. I've run into an obstacle that is preventing me from typing this class. If I have a UserCollection, it should only allow User objects into it. If I have a PostCollection, it should only allow Post objects. All Collections in this framework need to have certain basic functions, such as add, remove, iterate. I created an interface, but found that I couldn't do the following: interface ICollection { public function add($obj) } class PostCollection implements ICollection { public function add(Post $obj) {} } This broke it's compliance with the interface. But I can't have the interface strongly typed because then all Collections are of the same type. So I attempted the following: interface ICollection { public function add($obj) } abstract class Collection implements ICollection { const type = 'null'; } class PostCollection { const type = 'Post'; public function add($obj) { if(!($obj instanceof self::type)) { throw new UhOhException(); } } } When I attempt to run this code, I get syntax error, unexpected T_STRING, expecting T_VARIABLE or '$' on the instanceof statement. A little research into the issue and it looks like the root of the cause is that $obj instanceof self is valid to test against the class. It appears that PHP doesn't process the entire self::type constant statement in the expression. Adding parentheses around the self::type variable threw an error regarding an unexpected '('. An obvious workaround is to not make the type variable a constant. The expression $obj instanceof $this->type works just fine (if $type is declared as a variable, of course). I'm hoping that there's a way to avoid that, as I'd like to define the value as a constant to avoid any possible change in the variable later. Any thoughts on how I can achieve this, or have I take PHP to it's limit in this regard? Is there a way of "escaping" or encapsulating self::this so that PHP won't die when processing it?

  • Running Send_SMS method from BroadcastReceiver

    - by burmat
    My application is an auto-reply application for text messages. I have a BroadcastReceiver for when a message arrives, and I need it to run a public method (Send_SMS). SMS_Sender.sendSMS(phoneNumber, messageText); does not work however, and eclipse wants to change my method to static. This would not be an issue if I did not have more receivers that catch when the message is sent/delivered/etc in this class. These receivers are then errors for being contained in a static method. So my question is, how do I run this method from a broadcast receiver so I can send the auto reply whenever it is triggered with a received message? -Thank you in advance, Nate

  • BeginInvoke not invoking the target method in Release build

    - by Elan
    I have a method, which I wish to execute on the UI message pump and thus do the following: private void SomeMethod() { BeginInvoke(new MethodInvoker(MethodToInvoke)); } private void MethodToInvoke() { // This method contains code that I wish to execute on UI message pump. } Now, the above works just fine when I create a Debug build of the project. However, when I create a Release build, the "MethodToInvoke" method does not get invoked. Does anyone have any idea why this might be? Thanks, Elan

  • How to get a reference to a method's caller object from within the method in Objective-C

    - by shakeelw
    Hi guys. I have a few text fields and text views on my application's view. The keyboard comes up when I click in anyone of them. I have a method that gets called when any one of these objects is tapped in. However, I would like the method to execute its code only if the a certain Text Field(s) or a certain Text View(s) is tapped in. I would therefore like to have something like this in the method body: { if(currentField != mySpecialField) {return;} //Rest of the method code... } Now, my question is, how do I get a reference to the currently tapped in field so that I can perform the if-check. Thanks guys. I'm a total noobee in Objective-C. :(

  • SpringBatch Jaxb2Marshaller: different name of class and xml attribute

Unfortunately I can change neither the xml nor the java class. Is there a possibility to make Jaxb2Marshaller map the element 'input' to the class 'ProcessInput'?

  • How to dynamically set validation messages on properties with a class validation attribute

    - by Dan
    I'm writing Validation attribute that sits on the class but inspects the properties of the class. I want it to set a validation message on each of the properties it finds to be invalid. How do I do this? This is what I have got so far: [AttributeUsage(AttributeTargets.Class, AllowMultiple = false, Inherited = true)] public class LinkedFieldValidationAttribute : ValidationAttribute { private readonly string[] _properiesToValidate; public LinkedFieldValidationAttribute(params string[] properiesToValidate) { _properiesToValidate = properiesToValidate; } public override bool IsValid(object value) { PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(value); foreach (var propertyName in _properiesToValidate) { var propertyValue = properties.Find(propertyName, false).GetValue(value); //if value is invalid add message from base } //return validity } }

    Hi, I'm having some toubt here. Hope you guys can share out some programming tips. Just curious to know whether is it a good programming practice if I do something like the code below. class Outer { public: class Inner { public: Inner() {} } Outer() {} }; I have been doing this for structure where I only want my structure to be expose to my class instead of global. But the case is different here, I am using a class now? Have you guys facing such a situation before? Very much appreciated on any advice from you ;)

  • In what package should a "Settings" class be?

    - by Tom
    I've in the middle of building an application but found myself too easily creating new packages without keeping the project's structure in mind. Now, I'm trying to redo the whole project structure on paper first. I am using a Settings class with public properties, accessed as settings for several other classes around the project. Now, since this Settings class applies for the whole project, I am unsure if it should be packaged and if so, in what kind of package should it exist? Or should it be in the root (the default package) with the main application class? I've been thinking about putting it in my utils package, then again I don't think it really is an utlity. Any strategies on how to decide on such package structure for example for a Settings class?

  • Find tag that contains certain text and add a class

    - by David Gard
    I have the following HTML, and I need to add a class to both <li> and <a> where the text 'Charts' exists (so not the second line, but rather the 4th and 5th). I cannot change the output of the HTML. <div class="wp-submenu-wrap"> <div class="wp-submenu-head">Charts</div> <ul> <li class="wp-first-item"> <a class="wp-first-item" tabindex="1" href="admin.php?page=charts">Charts</a> </li> <li> <a tabindex="1" href="admin.php?page=add-chart">Add Chart</a> </li> </ul> </div> I've tried doing this by locating the <a> tag that contains the text, but it is not working. Can somebody please point me in the correct direction? Thanks. Code that I've tried - $(document).ready(function(){ if(pagenow === 'admin_page_edit-chart') { var page = $('.wp-submenu-wrap a:contains["Charts"]'); page.addClass('current'); page.parent('li').addClass('current'); } });

  • Java: is Exception class thread-safe?

    - by Vilius Normantas
    As I understand, Java's Exception class is certainly not immutable (methods like initCause and setStackTrace give some clues about that). So is it at least thread-safe? Suppose one of my classes has a field like this: private final Exception myException; Can I safely expose this field to multiple threads? I'm not willing to discuss concrete cases where and why this situation could occur. My question is more about the principle: can I tell that a class which exposes field of Exception type is thread-safe? Another example: class CustomException extends Exception { ... } Is this class thread-safe?

  • Problem using a method in Ruby

    - by Rafal
    I'm very new to Ruby (and OOP as well) and I don't know why the following thing doesn't work in Ruby I extended the String class with a new method. Easy enough. Now I want to extend the Fixnum class. A String object appears somewhere in the class, but I can't use the method that I defined earlier. Why? Is this normal?

  • Custom class object in Initialization list

    - by Michael
    I have a class Bar: class Bar { public: Bar(void); ~Bar(void); }; And a class Foo that gets a reference to Bar object as a constructor parameter and needs to save it in a private member bar_ : class Foo { private: Bar& bar_; public: Foo(Bar& bar) : bar_(bar) {} ~Foo(void) {} }; This doesn't compile : overloaded member function not found in 'Parser' missing type specifier - int assumed. Note: C++ does not support default-int Now i suspect couple of things that i need to assure, the second error is for Bar& bar_; declaration in Foo. Do i need to use an explicit constructor when declaring bar_ ? I am interested in learning how the compiler works regarding this matter, so a detailed explanation would be highly appreciated. Thanks.

  • Obtaining reference to Class instance by string name - VB.NET

    - by Jeff Williams
    Is it possible using Reflection or some other method to obtain a reference to a specific class instance from the name of that class instance? For example the framework for the applications i develop heavily uses public class instances such as: Public bMyreference as MyReference = new MyReference Then throughout the application bMyReference is used by custom controls and code. One of the properties of the custom controls is the "FieldName" which references a Property in these class instances (bMyReference.MyField) as a string. What i would like to be able to do is analyze this string "bMyReference.MyField" and then refer back to the actual Instance/Property. In VB6 I would use an EVAL or something simular to convert the string to an actual object but this obviously doesn't work in VB.net What I'm picturing is something like this Dim FieldName as String = MyControl.FieldName ' sets FielName to bMyReference.MyField Dim FieldObject() as String = FieldName.Split(".") ' Split into the Object / Property Dim myInstance as Object = ......... ' Obtain a reference to the Instance and set as myInstance Dim myProperty = myInstance.GetType().GetProperty(FieldObject(1))
