Attach an HREF and a class to an img link generated by the PhotoSlider script?

- by Frank Bailey

Hi folks, I'm using the very nice PhotoSlider script from http://opiefoto.com/articles/photoslider to create a slide show of images for one of my clients. This script replaces a previous hand-coded Javascript solution that allowed for the large image to be clicked resulting in a lightbox modal popup showing the full-size version of the clicked picture. Of course the client insists that this functionality remain intact, but the HTML code for the large image is generated on-the-fly by the PhotoSlider script itself. This means I'll need to modify the script slightly to attach a class ("lightbox") and an href (or just a click event, whichever makes more sense), but I'm not quite sure how best to accomplish this. I figure the event and class will have to be attached each time a thumbnail is clicked, but if this isn't the best way to do it any advice will be appreciated. The script is implemented into my page as can be seen here, without the click or class. I'd really appreciate any assistance stackoverflowites can offer. Thanks in advance!

Can I use string concatenation to define a class CONST in PHP?

- by selfsimilar

I know that you can create global constants in terms of each other using string concatenation: define('FOO', 'foo'); define('BAR', FOO.'bar'); echo BAR; will print 'foobar'. However, I'm getting an error trying to do the same using class constants. class foobar { const foo = 'foo'; const foo2 = self::foo; const bar = self::foo.'bar'; } foo2 is defined without issue, but declaring const bar will error out Parse error: syntax error, unexpected '.', expecting ',' or ';' I've also tried using functions like sprintf() but it doesn't like the left paren any more than the string concatenator '.'. So is there any way to create class constants in terms of each other in anything more than a trivial set case like foo2?

How to access CWebBrowser class instance (defined in a protected class) in a different class? C++

- by extintor

I have been playing with this webbrowser control example I got it working and added some timers using ON_WM_TIMER. Now I would like to access the m_Browser (CWebBrowser class instance) defined inside the protected CMyBrowserView class into a different class. (for example CMyBrowserApp in the code sample) and use .Navigate and other functions. How can I do this? (im using visual studio 6 c++)

What's safe to assume about the NSMutableArray / NSArray class cluster?

- by andyvn22

I know you shouldn't use this to decide whether or not to change an array: if ([possiblyMutable isKindOfClass:[NSMutableArray class]]) But say I'm writing a method and need to return either an NSMutableArray or an NSArray, depending on the mutability of possiblyMutable. The class using my method already knows whether or not it's acceptable to change the returned array. Whether or not it's acceptable to change the returned array directly correlates with whether or not it's acceptable to change possiblyMutable. In that specific case, is this code safe? It seems to me that if it's not acceptable to change the array, but we accidentally get a mutable array, it's ok, because the class using my method won't try to change it. And if it is acceptable to change the array, then we will always get possiblyMutable as an NSMutableArray (though this is the part I'm not entirely clear on). So... safe or not? Alternatives?

How do I ensure my abstract class's function can only operate on extenders of the same type as the c

- by incrediman

For example, let's say this is my abstract class: abstract class A{ int x; int y; void foo(A fooMe); } ...and B and C are two classes which extend A. What I want is for B to only be able to call foo() on other Bs, and for C to only be able to call foo() on other Cs. But I want this to be out of the hands of the programmer who's extending my A class - that is, I want a way to ensure this functionality within As code alone. What can I do? (If possible) I'd like to avoid any hack or generics solution that's too messy - I still want foo to be able to be called like this, for example: B b=new B(); B bb=new B(); bb.foo(b);

'array bound is not an integer constant' when defining size of array in class, using an element of a const array

- by user574733

#ifndef QWERT_H #define QWERT_H const int x [] = {1, 2,}; const int z = 3; #endif #include <iostream> #include "qwert.h" class Class { int y [x[0]]; //error:array bound is not an integer constant int g [z]; //no problem }; int main () { int y [x[0]]; //no problem Class a_class; } I can't figure out why this doesn't work. Other people with this problem seem to be trying to dynamically allocate arrays. Any help is much appreciated.

How to define a new type (class) in Python using C API?

- by ~mech

Hi, I am trying to use the Python C API to define a new class inside a module that would expose certain functionality written in C to Python code. I specifically want to have it in the form of a class and not a set of module functions. However, I can't find anything regarding this particular task in the official documentation. The closest I could find is PyClass_New function (in the Python.h header) but it is not mentioned anywhere in the official docs, so I assume it is not supposed to be used. So, what is the proper way to define a new Python class from C code? Thanks.

Using the StopWatch class to calculate the execution time of a block of code

- by vik20000in

Many of the times while doing the performance tuning of some, class, webpage, component, control etc. we first measure the current time taken in the execution of that code. This helps in understanding the location in code which is actually causing the performance issue and also help in measuring the amount of improvement by making the changes. This measurement is very important as it helps us understand the problem in code, Helps us to write better code next time (as we have already learnt what kind of improvement can be made with different code) . Normally developers create 2 objects of the DateTime class. The exact time is collected before and after the code where the performance needs to be measured. Next the difference between the two objects is used to know about the time spent in the code that is measured. Below is an example of the sample code. DateTime dt1, dt2; dt1 = DateTime.Now; for (int i = 0; i < 1000000; i++) { string str = "string"; } dt2 = DateTime.Now; TimeSpan ts = dt2.Subtract(dt1); Console.WriteLine("Time Spent : " + ts.TotalMilliseconds.ToString()); The above code works great. But the dot net framework also provides for another way to capture the time spent on the code without doing much effort (creating 2 datetime object, timespan object etc..). We can use the inbuilt StopWatch class to get the exact time spent. Below is an example of the same work with the help of the StopWatch class. Stopwatch sw = Stopwatch.StartNew(); for (int i = 0; i < 1000000; i++) { string str = "string"; } sw.Stop(); Console.WriteLine("Time Spent : " +sw.Elapsed.TotalMilliseconds.ToString()); [Note the StopWatch class resides in the System.Diagnostics namespace] If you use the StopWatch class the time taken for measuring the performance is much better, with very little effort.

Data classes: getters and setters or different method design

- by Frog

I've been trying to design an interface for a data class I'm writing. This class stores styles for characters, for example whether the character is bold, italic or underlined. But also the font-size and the font-family. So it has different types of member variables. The easiest way to implement this would be to add getters and setters for every member variable, but this just feels wrong to me. It feels way more logical (and more OOP) to call style.format(BOLD, true) instead of style.setBold(true). So to use logical methods insteads of getters/setters. But I am facing two problems while implementing these methods: I would need a big switch statement with all member variables, since you can't access a variable by the contents of a string in C++. Moreover, you can't overload by return type, which means you can't write one getter like style.getFormatting(BOLD) (I know there are some tricks to do this, but these don't allow for parameters, which I would obviously need). However, if I would implement getters and setters, there are also issues. I would have to duplicate quite some code because styles can also have a parent styles, which means the getters have to look not only at the member variables of this style, but also at the variables of the parent styles. Because I wasn't able to figure out how to do this, I decided to ask a question a couple of weeks ago. See Object Oriented Programming: getters/setters or logical names. But in that question I didn't stress it would be just a data object and that I'm not making a text rendering engine, which was the reason one of the people that answered suggested I ask another question while making that clear (because his solution, the decorator pattern, isn't suitable for my problem). So please note that I'm not creating my own text rendering engine, I just use these classes to store data. Because I still haven't been able to find a solution to this problem I'd like to ask this question again: how would you design a styles class like this? And why would you do that? Thanks on forehand!

Is this the correct approach to an OOP design structure in php?

- by Silver89

I'm converting a procedural based site to an OOP design to allow more easily manageable code in the future and so far have created the following structure: /classes /templates index.php With these classes: ConnectDB Games System User User -Moderator User -Administrator In the index.php file I have code that detects if any $_GET values are posted to determine on which page content to build (it's early so there's only one example and no default): function __autoload($className) { require "classes/".strtolower($className).".class.php"; } $db = new Connect; $db->connect(); $user = new User(); if(isset($_GET['gameId'])) { System::buildGame($gameId); } This then runs the BuildGame function in the system class which looks like the following and then uses gets in the Game Class to return values, such as $game->getTitle() in the template file template/play.php: function buildGame($gameId){ $game = new Game($gameId); $game->setRatio(900, 600); require 'templates/play.php'; } I also have .htaccess so that actual game page url works instead of passing the parameters to index.php Are there any major errors of how I'm setting this up or do I have the general idea of OOP correct?

Why does Scala require functions to have explicit return type?

- by garbage collection

I recently began learning to program in Scala, and it's been fun so far. I really like the ability to declare functions within another function which just seems to intuitive thing to do. One pet peeve I have about Scala is the fact that Scala requires explicit return type in its functions. And I feel like this hinders on expressiveness of the language. Also it's just difficult to program with that requirement. Maybe it's because I come from Javascript and Ruby comfort zone. But for a language like Scala which will have tons of connected functions in an application, I cannot conceive how I brainstorm in my head exactly what type the particular function I am writing should return with recursions after recursions. This requirement of explicit return type declaration on functions, do not bother me for languages like Java and C++. Recursions in Java and C++, when they did happen, often were dealt with 2 to 3 functions max. Never several functions chained up together like Scala. So I guess I'm wondering if there is a good reason why Scala should have the requirement of functions having explicit return type?

jQuery Hover functions

Thus far you guys have been wildly helpful with me getting this little ditty working just so.

I'd like it to remain slideout as someone hovers the nested li's. So the slide should only happen on hover for the tier_1 elements. Also I would like, on hover to add an "active" class to the a element on the tier_1 links. So [a class="enviro"..] would, on hover, become [a class="enviro active"]. This is then removed when one of the other tier_1 items is hovered. This way the pretty color icon can stay visible while someone looks at the nested elements. Not even sure all that is possible with hover, but I figured if anyone would know a way it would be here.

SQLAuthority News – First SQL Bangalore Event Report – Nov 24, 2012 – SQL Server User Group Bangalore

- by pinaldave

A very common question I often receive - Do we have SQL Server User Group in Bangalore? Yes! SQL Bangalore – we had very first meeting on Nov 24, 2012 and very soon we are going to have another User Group meeting. The goal is to keep up a monthly rhythm of User Group meeting. If you are in Bangalore area please join the Facebook page and you will keep on getting regular update about SQL Server. In the very first meeting we have five 30 minute session and had a fantastic time. We had the best of the best speakers presenting all the five sessions. The event was inaugurated by Vinod Kumar M by presenting on T-SQL Pitfalls. His excellent and eye-opening session was followed by Manas Dash. He enlightened everybody with functions introduced in SQL Server 2012. We had a surprise guest from Mumbai – Raj Chaodhary. If you know him he has a very interesting way to present sessions and he presented on SQL Joins. His hard to follow act was followed by Sudeepta who presented on Contained Database. This subject is quite entertaining and interesting. My session was last in order and I was eagerly waiting to present. I had decided to do something new this time so I had created around 52 slides and two demos. I was committed to go over all the 52 slides and both of the demos in 25 minutes of the time. I had interesting story as well. Though, I was a bit nervous I was able to go over a complete slide deck and demo in 25 minutes of the time I had. We also were very fortunate to have international guest Lynn Langit from USA present at the event as well. She presented an overview of the Big Data in very little time – something not everyone can do it efficiently. We are very thankful to our sponsor Pluralsight for awarding USD 300 worth Annual Subscription. It was the most awaited moment of the day. Well, overall we had a great fun with 100+ attendees learning SQL Server.

A first look at SignalR

- by Rick Strahl

Last month I finally had a chance to use SignalR in a live project for the first time, and I've been impressed by what this technology offers to .NET developers. It's easy to use and provides rich real-time two way messaging between client and server applications, as well as the ability to broadcast message to all connected clients. This is technology that offers many opportunities to rethink of what we can build with Web applications.

Loading class instance from XML with Texture2D

- by Thegluestickman

I'm having trouble with XML and XNA. I want to be able to load weapon settings through XML to make my weapons easier to make and to have less code in the actual project file. So I started out making a basic XML document, something to just assign variables with. But no matter what I changed it gave me a new error every time. The code below gives me a "XML element 'Tag' not found", I added and it started to say the variables weren't found. What I wanted to do in the XML file as well, was load a texture for the file too. So I created a static class to hold my texture values, then in the Texture tag of my XML document I would set it to that instance too. I think that's were the problems are occuring because that's where the "XML element 'Tag' not found" error is pointing me too. My XML document: <XnaContent> <Asset Type="ConversationEngine.Weapon"> <weaponStrength>0</weaponStrength> <damageModifiers>0</damageModifiers> <speed>0</speed> <magicDefense>0</magicDefense> <description>0</description> <identifier>0</identifier> <weaponTexture>LoadWeaponTextures.ironSword</weaponTexture> </Asset> </XnaContent> My Class to load the weapon XML: public class Weapon { public int weaponStrength; public int damageModifiers; public int speed; public int magicDefense; public string description; public string identifier; public Texture2D weaponTexture; } public static class LoadWeaponXML { static Weapon Weapons; public static Weapon WeaponLoad(ContentManager content, int id) { Weapons = content.Load<Weapon>(@"Weapons/" + id); return Weapons; } } public static class LoadWeaponTextures { public static Texture2D ironSword; public static void TextureLoad(ContentManager content) { ironSword = content.Load<Texture2D>("Sword"); } } I'm not entirely sure if you can load textures through XML, but any help would be greatly appreciated.

What's up with LDoms: Part 2 - Creating a first, simple guest

- by Stefan Hinker

Welcome back! In the first part, we discussed the basic concepts of LDoms and how to configure a simple control domain. We saw how resources were put aside for guest systems and what infrastructure we need for them. With that, we are now ready to create a first, very simple guest domain. In this first example, we'll keep things very simple. Later on, we'll have a detailed look at things like sizing, IO redundancy, other types of IO as well as security. For now,let's start with this very simple guest. It'll have one core's worth of CPU, one crypto unit, 8GB of RAM, a single boot disk and one network port. CPU and RAM are easy. The network port we'll create by attaching a virtual network port to the vswitch we created in the primary domain. This is very much like plugging a cable into a computer system on one end and a network switch on the other. For the boot disk, we'll need two things: A physical piece of storage to hold the data - this is called the backend device in LDoms speak. And then a mapping between that storage and the guest domain, giving it access to that virtual disk. For this example, we'll use a ZFS volume for the backend. We'll discuss what other options there are for this and how to chose the right one in a later article. Here we go: root@sun # ldm create mars root@sun # ldm set-vcpu 8 mars root@sun # ldm set-mau 1 mars root@sun # ldm set-memory 8g mars root@sun # zfs create rpool/guests root@sun # zfs create -V 32g rpool/guests/mars.bootdisk root@sun # ldm add-vdsdev /dev/zvol/dsk/rpool/guests/mars.bootdisk \ mars.root@primary-vds root@sun # ldm add-vdisk root mars.root@primary-vds mars root@sun # ldm add-vnet net0 switch-primary mars That's all, mars is now ready to power on. There are just three commands between us and the OK prompt of mars: We have to "bind" the domain, start it and connect to its console. Binding is the process where the hypervisor actually puts all the pieces that we've configured together. If we made a mistake, binding is where we'll be told (starting in version 2.1, a lot of sanity checking has been put into the config commands themselves, but binding will catch everything else). Once bound, we can start (and of course later stop) the domain, which will trigger the boot process of OBP. By default, the domain will then try to boot right away. If we don't want that, we can set "auto-boot?" to false. Finally, we'll use telnet to connect to the console of our newly created guest. The output of "ldm list" shows us what port has been assigned to mars. By default, the console service only listens on the loopback interface, so using telnet is not a large security concern here. root@sun # ldm set-variable auto-boot\?=false mars root@sun # ldm bind mars root@sun # ldm start mars root@sun # ldm list NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv- UART 8 7680M 0.5% 1d 4h 30m mars active -t---- 5000 8 8G 12% 1s root@sun # telnet localhost 5000 Trying 127.0.0.1...

Ethernet address 0:21:28:24:1b:50, Host ID: 85241b50. {0} ok We're done, mars is ready to install Solaris, preferably using AI, of course ;-) But before we do that, let's have a little look at the OBP environment to see how our virtual devices show up here: {0} ok printenv auto-boot? auto-boot? = false {0} ok printenv boot-device boot-device = disk net {0} ok devalias root /virtual-devices@100/channel-devices@200/disk@0 net0 /virtual-devices@100/channel-devices@200/network@0 net /virtual-devices@100/channel-devices@200/network@0 disk /virtual-devices@100/channel-devices@200/disk@0 virtual-console /virtual-devices/console@1 name aliases We can see that setting the OBP variable "auto-boot?" to false with the ldm command worked. Of course, we'd normally set this to "true" to allow Solaris to boot right away once the LDom guest is started. The setting for "boot-device" is the default "disk net", which means OBP would try to boot off the devices pointed to by the aliases "disk" and "net" in that order, which usually means "disk" once Solaris is installed on the disk image. The actual devices these aliases point to are shown with the command "devalias". Here, we have one line for both "disk" and "net". The device paths speak for themselves. Note that each of these devices has a second alias: "net0" for the network device and "root" for the disk device. These are the very same names we've given these devices in the control domain with the commands "ldm add-vnet" and "ldm add-vdisk".
