• Admin panel - what is the best way to display "static" data in the layout?

  - by rkj

  I'm about to write a admin panel for my CMS written in CodeIgniter. There will be some user information visible at all time - both in the layout's header section and the sidebar. I'm used to do it in a way that I personally hope and think could be done a lot easier, since I'm tired of sending the same parametres to the view over and over again, when it's dynamic data that needs to be displayed on every page anyways (such as unread messages, username, name, status, etc). I'll need controllers and models, I know that, but do I have to pass, just for an example, the user's username, unread messages etc. every time I need to load a view? Should I do some kind of library for this? Now my question is: How would I do it when it comes to best practice and for making it easy to maintain in the future? I hope my question is understandable :)

• Do private classes need to be accessed by properties?

  - by Andy

  I am using an instance of a private class as the state object supplied to a stream.BeginRead operation. (The class is private to my main stream reading/writing class.) public class MainClass { // ... private class ResponseState { public IResponse response; public Stream stream; public byte[] buffer = new byte[1024]; } } Access to the class is via the fields directly. Should I really be providing access to the class via properties in this case, even though it is only to be used for holding state? Interested to know what others do.

• Code generation tool, to create C# adapter classes for unit testing?

  - by RyBolt

  I know I wouldn't need this with Typemock, however, with something like MoQ , I need to use the adapter pattern to enable the creation of mocks via interfaces for code I don't control. For example, TcpClient is a .NET class, so I use adapter pattern to enable mocking of this object, b/c I need an interface of that class. I then produce interface ITcpClient, that can then be implemented via a TcpClientAdapter class, which is just plain vanilla adapter pattern implementation. I am looking for a tool to do this automatically (creation of interface and adapter), I would think there is one out there somewhere? (or is everyone just hand coding these)

• WP7 - attempt to select and use application static resource in codebehind not working (no resources found).

  - by pearcewg

  With Windows Phone 7, I'm attempting to dynamically add controls to and object in codebehind, and apply a StaticResource to the new control. Xaml file sample: <phone:PhoneApplicationPage.Resources> <ControlTemplate x:Key="PushpinControlTemplateBlue" TargetType="my2:Pushpin"> ... </ControlTemplate> </phone:PhoneApplicationPage.Resources> Codebehind sample: >Pushpin myPush = new Pushpin(); >myPush.Location = new GeoCoordinate(52.569593, -0.9261151403188705); >myPush.Content = ""; >myPush.Template = (ControlTemplate)Application.Current.Resources["PushpinControlTemplateBlue"]; >mapMain.Children.Add(myPush); When I debug, and look at "Application.Current.Resources", there are no items in the collection, so the item is added to the controls list, but doesn't show up because it has no content. Is there something simple I'm doing wrong? How do I correctly access the resource?

• How do I create static instances of a class inside that class?

  - by wehas

  I have a class Color that holds values for the red, green, and blue channels of a color. The class constructor lets you create a new color by specifying values for the three channels. However, for convenience, I would also like to have some "premade" colors available for the programmer. For example instead of having something like DrawRectangle(new Color(1, 0, 0)); you would be able to say DrawRectangle(Color.Red); Where Color.Red is an instance of Color that lives inside the Color class. How can I declare these instances of Color inside the Color class? If there is a name for this type of technique I'd like to know it as I had no idea what search terms to use when I was looking for help online.

• How to instantiate objects of classes that have dependencies injected?

  - by chester89

  Let's say I have some class with dependency injected: public class SomeBusinessCaller { ILogger logger; public SomeBusinessCaller(ILogger logger) { this.logger = logger; } } My question is, how do I instantiate an object of that class? Let's say I have an implementation for this, called AppLogger. After I say ObjectFactory.For<ILogger>().Use<AppLogger>(); how do I call constructor of SomeBusinessCaller? Am I calling SomeBusinessCaller caller = ObjectFactory.GetInstance<SomeBusinessCaller>(); or there is a different strategy for that?

• Is it okay to use zoom:1 in my css classes?

  - by Spines

  Whenever I find IE is displaying my website weird (different from chrome and firefox), I try putting a zoom:1 in the css class for the part that is being displayed weird. A lot of the time this fixes the problem and makes it look consistent with the other browsers. Is it a problem to use zoom:1? I know my CSS won't validate, but are there any real world problems that can arise if I rely too much on using zoom:1?

• C++: Is there a way to limit access to certain methods to certain classes without exposing other pri

  - by dadads

  I have a class with a protected method Zig::punt() and I only want it to be accessible to the class "Avocado". In C++, you'll normally do this using the "friend Avocado" specifier, but this will cause all of the other variables to become accessible to "Avocado" class; I don't want this because this breaks encapsulation. Is what I want impossible, or does there already exist an obscure trick out there that I can use to achieve what I want? Or possibly alternative class design patterns that'll achieve the same thing? Thanks in advance for any ideas!

• Can I add a custom method to Core Data-generated classes?

  - by Andy

  I've got a couple of Core Data-generated class files that I'd like to add custom methods to. I don't need to add any instance variables. How can I do this? I tried adding a category of methods: // ContactMethods.h (my category on Core Data-generated "Contact" class) #import "Contact.h" @interface Contact (ContactMethods) -(NSString*)displayName; @end ... // ContactMethods.m #import "ContactMethods.h" @implementation Contact (ContactMethods) -(NSString*)displayName { return @"Some Name"; // this is test code } @end This doesn't work, though. I get a compiler message that "-NSManagedObject may not respond to 'displayName' " and sure enough, when I run the app, I don't get "Some Name" where I should be seeing it.

• Easy way to convert a Doctrine_Collection of Model classes to an array of simple objects?

  - by Alex

  To clearly separate the Controller and View layers, I do not longer want to pass full objects to my views. Instead I want to pass only arrays and objects that contain the data but do not have any methods. Otherwise a view script would be able to delete Doctrine records or traverse in the object tree to data that was not intended for the view.

• (WinForm/.net) Databind List Of Classes To A DataGridView. But Not Show Certain Public Properties

  - by Pyronaut

  I'm not even sure if i'm doing this correctly. But basically I have a list of objects that are built out of a class. From there, I am binding the list to a datagrid view that is on a Windows Form (C#) From there, it shows all the public properties of the object, in the datagrid view. However there is some properties that i still need accessible from other parts of my application, but aren't really required to be visible in the DataGridView. So is there an attribute or something similar that I can write above the property to exclude it from being shown. P.S. Im binding at runtime. So i cannot edit the columns via the designer. P.P.S. Please no answers of just making public variables (Although if that is the only way, let me know :)).

• which text writing classes are the most efficient for writing lots of small files?

  - by Robert H

  I have to write 300+ files to a server share on a hourly basis. A quick implementation using CreateText takes approximately 1.4 seconds per file. I know there is a better way to do this, but I am unsure which way is actually the quickest/most efficient; hence my question: Which text writing class is the most efficient for writing hundreds of small files ( 336 bytes on average ) to a server share?

• Visual Studio 2008 - Is it possible for two projects to share common classes?

  - by John M

  In Visual Studio 2008 I know its possible to have one solution with two (or more) projects. Is it possible OR How is it possible for the projects to share common class files? For example - Project 1 has a log file handling class. Can Project 2 reference it? My hope is to increase code re-use and avoid two copies of the same thing that need to be maintained. The target is Winforms C# (3.5)

• Swing: easiest way to align width of [dynamic][static][dynamic] components?

  - by java.is.for.desktop

  What is the easiest way in standard Java Swing to align three components in such a way that: the dynamic widths of Component1 and Component3 are adjusted to be equal, while Component2 (which is in between) has constant width? Imagine we have some resizable JPanel (such as inside a JFrame). Small width should look like this: [----------------whole JPanel----------------] [--Component1--] [Component2] [--Component3--] Big width should look like this: [------------------------whole JPanel------------------------] [------Component1------] [Component2] [------Component3------] Note: I just "trialed-and-errored" with GroupLayout for too long.

• How can I get class, property, and method data from files without executing their code, similar to R

  - by Chris

  I have a bunch of PHP files with classes, in them (although I can't be 100% sure that they won't have code outside of classes in them too), and I need to parse these files to get information about the classes, such as the names of the classes, the methods, the properties, whether they are private/public/static, etc. I looked at PHP's reflection classes and this is very close to what I want but the reflection doesn't seem to use external files and it appears to need to define the classes first. I need to make sure that none of the code is executed and I will be editing the files so I can't guarantee that they will even be error-free. Any suggestions? Thanks.

• TypeError: object not callable when making instance

  - by TSM

  I've searched around other threads with similar questions, but I'm not finding the answer. Basically, I have a class: import Android_Class class Android_Revision(object): def __init__(self): # dict for storing the classes in this revision # (format {name : classObject}): self.Classes = {} self.WorkingClass = Android_Class() self.RevisionNumber = '' def __call__(self): print "Called" def make_Class(self, name): newClass = Android_Class(name) self.Classes.update({name : newClass}) self.WorkingClass = newClass def set_Class(self, name): if not(self.Classes.has_key(name)): newClass = Android_Class(name) self.Classes.update({name : newClass}) self.WorkingClass = self.Classes.get(name) I'm trying to make an instance of this class: Revision = Android_Revision() and that's when I'm getting the error. I'm confused because I have another situation where I'm doing almost the exact same thing, and it's working fine. I can't figure out what differences between the two would lead to this error. Thanks.

• is it good idea to remember html tags in css classes and Ids?

  - by metal-gear-solid

  If we keep tag name within selectors. For example: #divMainContentBody { … } .spanImportant { … } This minimizes the need to switch between your stylesheet and your markup, since the ID and class already tells you what element type it is referring to.

• c++: at what point should I start using "new char[N]" vs a static buffer "char[Nmax]"

  - by dan

  My question is with regard to C++ Suppose I write a function to return a list of items to the caller. Each item has 2 logical fields: 1) an int ID, and 2) some data whose size may vary, let's say from 4 bytes up to 16Kbytes. So my question is whether to use a data structure like: struct item { int field1; char field2[MAX_LEN]; OR, rather, to allocate field2 from the heap, and require the caller to destroy when he's done: struct item{ int field1; char *field2; // new char[N] -- destroy[] when done! Since the max size of field #2 is large, is makes sense that this would be allocated from the heap, right? So once I know the size N, I call field2 = new char[N], and populate it. Now, is this horribly inefficient? Is it worse in cases where N is always small, i.e. suppose I have 10000 items that have N=4?

• How can I remove all classes that are not named "message" from an element?

  - by Marilou

  I have the following: <div id="abc"> </div> Inside that div there can be one only of the following: <p class="message"> <p class="message error"></p> <p class="message warning"></p> <p class="message success"></p> <p class="message loading"></p> Is there a way that I can find and remove only the class from the <p> element that's NOT "message". I realize I could remove everything and then add what I need with .removeClass() but this won't work for me as after I previously added the message class I did some CSS changes and these will be lost if I remove all and then add again the message class.

• Do you leave historical code commented out in classes that you update?

  - by 18Rabbit

  When you need to obsolete a section of code (say either the business rules changed, or the old system has been reworked to use a new framework or something) do you delete it from the file or do you comment it out and then put in the new functionality? If you comment it out, do you leave a note stating why it was removed and what it was originally intended to do? I ask mainly because I've done a lot of contract work for different places over the years and sometimes it's like excavating a tomb to find the actual code that is still being used. Why comment it out and leave it in the file if source control has a record of what used to be there? If you comment out a method do you also comment out/delete any methods that were exclusively used by that method? What do you think the best practices for this should be?
