• Data Structure Brushup (Java)

  - by Daddy Warbox

  This should be easy for many of you, but for me it's just another bit of rust needing to be chipped away as I get back into basic Java coding. Using bloody associative arrays for so long in other languages have turned me nice and spoiled. :P My problem is simple: I'm storing a set of objects, each containing a string and a number, in a list. I would like each object inserted into this list to be sorted alphabetically by its string. I would also like to be able to retrieve objects from the list by their string as well. I would like to do this as formally and/or efficiently as possible. Is there something already available in the Java standard libraries for this?

• Is it possible to disable auto formatting only for Html pages (not c#) on VS2010?

  - by ensecoz

  During the design html pages or aspx pages, I like to do the pure coding without Html Designer. The problem is that I like to have the following format on html page for better readability. <div> <% if (1 == 1) { %> Hello <% } else { %> World <% } %> </div> As you can guess, whenever you type '}' or ';' or etc, visual studio try to do the auto format and change to the following format <div> <% if (1 == 1) { %> Hello <% } else { %> World <% } %> </div> The question is "Is it possible to disable auto formatting just only for HTML pages on VS2010? (NOT for C# code, I still like to have auto formatting for C# pages)"

• Where can I find the project templates for ASP.NET MVC 1.0?

  - by Jason

  I would like to edit the ASP.NET MVC templates for Visual Studio so that any new action or controller created has a specific piece of code within it by default. For instance, I'd like to replace the generated: public ActionResult MyAction() { return View(); } with a specific coding standard we prefer to use within in my team. eg: public ActionResult About() { try { DoStuff(); return View(); } catch(Exception) { HandleException(); } } I've looked through the filesystem, but I cannot find anything specific that relates to the ASP.NET mvc templates. Anyone know where they are?

• Mysql database structure...

  - by Patrick

  I'm creating a members site, and I'm currently working on the user Preference settings. Should I create a table with all the preference fields (about 17 fields) or should I include them in the main member table along with the account settings? Is there a limit as to how many fields I should have in a table? currently the member table has about 21 fields... not sure if its okay to add another 17 more fields when I can easily just put them in another table. It'll take more coding to pull up the data though... any sugguestions?

• Adding interfaces that won't be actually used

  - by devoured elysium

  I currently have two interfaces(that I'll name here IA and IB): interface IA { int Width; int Height; ... } interface IB { int Width; int Height; ... } that share the same two properties: they both have a Width and a Height property. I was thinking if there is any point in defining an IMatrix interface containing a Width and Height properties: interface IMatrix { int Width; int Height; } The thing is that although they share both the same properties, I won't make use of polymorphism with IMatrix in any of my coding: i.e., there won't by any situation where I'll want to use an IMatrix, I'll just want to use IA and IB. Adding an IMatrix seems more like over-engineering than other thing, but I'd like to ask you guys what your opinion is on the matter. Thanks

• How to create wordpress-like option table and get values for each row? (PHP-MySQL)

  - by Nacho

  Hi guys. I'm looking to create an options table in my db that makes every record a system option, so i can work with a little number of fields. my db has the following structure: 3 columns named id, name, and value following data is inserted as an example -- id - name - value 1 - uri - www.example.com 2 - sitename - Working it out 3 - base_folder - /folder1/folder2/ 4 - slogan - Just a slogan for the site -- that way i can include a large number of customizable system options very easily the problem is that i don't know how to retrieve them how do i get the value of uri and store it as a var? and better yet, how do i get, for exmaple, values of id 1 and 4 only without making a query each time? (i assume multiple queries are useless and a pretty ugly method) i know the question is pretty basic but i'm lost here. i'd really appreciate your answer! Thanks in advance

• How to go about finding ad-hoc development work on the web?

  - by DaveDev

  I'm wondering if its possible to find supplementary development work on line? I have some time available to me in the evenings and I thought it might be good to use it productively. It'd be great if there was a site that I could apply to do some ad-hoc coding for anyone who needs it. Something like 'I need a class that does XY & Z', and I could do that. Is there anything like this out there? Can somebody supply me with some info? Thanks

• SqlCE Flush Interval - Will the default setting lead to corruption?

  - by NormD

  SqlCE has a parameter set on the Connect String called Flush Interval. It is defined as: The interval time (in seconds) before all committed transactions are flushed to disk. If not specified, the default value is 10. I thought that a committed transaction, by definition, is a transaction that has been flushed to disk, specifically the database file. If a transaction is only stored in RAM then cannot the transaction be easily lost? I thought that transactions were first written to a log file and then applied to the database file itself, so perhaps this parameter could mean the time to wait until the transaction log is applied to the database file? I would have thought that this parameter should be 0.

• Utilizing a third party application for GitHub in a django project

  - by Smock

  I'm trying to use a third party application located here: git://github.com/Star2Billing/django-audiofield.git I'm using Aptana Studio as my IDE. I created my project and then I clicked on the project and imported the app from the github location. It looked like it imported. I wanted to check that it imported properly before beginning any real coding so I performed manage.py validate. I got a message that stated: "No module named audiofield". I added the app to my Installed Apps settings and followed the installation instructions. I'm not sure if I'm importing it incorrectly. Also, I'm using virtualenv in Aptana. I'm not sure if this may have added to the problem. Please help.

• Args error in main method for client-server program

  - by socket

  Hi I have a client and server program, all the coding is done and compiles, the client has a GUI and the server is command line. The program uses sockets. But when I run the client to connect to the server it keeps coming with the error message: "Usage: TodoClient []", rather than connecting to the server and starting up. This is where the problem lies: public static void main(String[] args) { TodoClient client; if (args.length > 2 || args.length == 0) { System.err.println("Usage: TodoClient <host> [<port>]"); } else if (args.length == 1) { client = new TodoClient(args[0], DEFAULT_PORT); } else { client = new TodoClient(args[0], Integer.parseInt(args[1])); } } Thank You

• Advanced Memory Editing/Function Calling

  - by Saustin

  Hi, I've gotten extremely interested into coding trainers (Program that modifies value of a different process) for video games. I've done the simple 'god-mode' and 'unlimited money' things, but I want to do alot more than that. (Simple editing using WriteProcessMemory) There are memory addresses of functions on the internet of the video game I'm working on, and one of functions is like "CreateCar" and I'm wanting to call that function from an external program. My question: How can I call a function from an external process in C/C++, provided the function address, using a process handle or other method. PS: If anyone could link me to tools (I've got debuggers, no need for more..) that help with this sort of thing, that'd be nice.

• How often does memcache on Google AppEngine lose data?

  - by Freed

  Memcache in general and on AppEngine in specific is unreliable in the sense that my data may be deleted from the cache for whatever reason at any point in time. However, in some cases there might be cases where a small risk may be worth the added performance using memcache could give, such as updating some data in memcache that gets saved periodically to some other, more reliable storage. Are there any numbers from Google that could give me an indication of the actual probability that a memcache entry would be lost from the cache before its expiration time, given that I keep within my quotas? Are there any reasons other than hardware failure and administrative operations such as machines at the data centers being upgraded/moved/replaced that would cause entries to be removed from memcache prematurely?

• What's the difference between FireBug's conole.log() and console.debug() ?

  - by 6bytes

  A very simple code to illustrate the difference. var x = [0, 3, 1, 2]; console.debug('debug', x); console.log('log', x); // above display the same result x.splice(1, 2); // below display kind of a different result console.debug('debug', x); console.log('log', x); The javascript value is exactly the same but console.log() displays it a bit differently than before applying splice() method. Because of this I lost quite a few hours as I thought splice is acting funny making my array multidimensional or something. I just want to know why does this work like that. Does anyone know? :)

• dynamically double image size

  - by Edan Duarte

  I have an embarrassingly simple question: How can I display an image at double its size without hard coding the width and height attributes? Here's what I tried, but I ended up having to just enter 1000 for width and height. Is something wrong with my function? Thanks! <img onload="double(self.id);" name="bigPic" id="bigPic" src="album1.jpg" height="1000" width="1000"/> function double(id) { var img = document.getElementById(id); var dblWdth = img.width * 2; var dblHt = img.height * 2; img.height = dblHt; img.width = dblWdth; }

• "...redeclared as different kind of symbol"?

  - by CodeNewb

  #include <stdio.h> #include <math.h> double integrateF(double low, double high) { double low = 0; double high = 20; double delta_x=0; double x, ans; double s = 1/2*exp((-x*x)/2); for(x=low;x<=high;x++) delta_x = x+delta_x; ans = delta_x*s; return ans; } It says that low and high are "redeclared as different type of symbol" and I don't know what that means. Basically, all I'm doing here (READ: trying) is integrating from low (which I set to 0) to high (20) to find the Riemann sum. The for loop looks kinda trippy too...I'm so lost.

• Setting height of a DIV to correspond with location of anchor inside said DIV

  - by filip

  Core issue : http://jsfiddle.net/pipip/P46Xg/ I have a div container with a few paragraphs of text, and inside one of these paragraphs is the following anchor <a id="stop" /> The container is set to overflow:hidden Is it possible with javascript / JQuery to set the height of the container so that the bottom of the container stops exactly at or below the anchor? Added Depth & Background : http://jsfiddle.net/pipip/yj9dB/ This would be used for a modified JQuery Slider. Where someone using a CMS could type [readmore] anywhere into the Content field, which would be replaced by the above anchor via PHP. This way they would be easily able to control where the Read More break appears within the container. In the associated example I am hard-coding the height to 75px, although what I want is for the height to be dependent on the location of the anchor id="stop" in the text. Thanks. If this is an awful way to go about it, I'm all ears!

• 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.

• Facebook login within an iframe (but outside FB)

  - by Cystack

  At some point in my application, I use an iframe. In this iframe, some Facebook stuff could be useful and for that, I use the graph API a lot. Problem is : when someone isn't logged in to facebook or hasn't allowed my application yet, they are prompted to click the "connect with facebook" button. But as soon as they click it, the iframe gets destroyed and the top page is replaced with the Facebook login page. Eventually the top page is redireccted to the previous iframe URL, but the former parent page is lost forever. Is this the intended behaviour of FB connect ? Is there a way to avoid it or to hack around it ? (maybe using a popup instead of an iframe, but that sounds ugly (uglier than an iframe)). I am currently using the PHP SDK Thanks a lot

• access a property via string with array in php?

  - by sprugman

  (This is in drupal, but I don't really think that matters.) I have a big list of properties that I need to map between two objects, and in one, the value that I need to map is buried inside an array. I'm hoping to avoid hard-coding the property names in the code. If I have a class like this: class Product { public $colors, $sizes; } I can access the properties like this: $props = array('colors', 'sizes'); foreach ($props as $p) { $this->$p = $other_object->$p; } As far as I can tell, if each of the properties on the left are an array, I can't do this: foreach ($props as $p) { $this->$p[0]['value'] = $other_object->$p; } Is that correct, or am I missing some clever way around this?
