  • Boost multi_index ordered_unique Median Value

    - by Autopulated
    I would like to quickly retrieve the median value from a boost multi_index container with an ordered_unique index, however the index iterators aren't random access (I don't understand why they can't be, though this is consistent with std::set...). Is there a faster/neater way to do this other than incrementing an iterator container.size() / 2 times?

  • What does this line of code mean?

    - by Victor
    Hi, I am wondering what this line of code mean? b = (gen_rand_uniform()>0.5)?1:0; The gren_rand_uniform() is a function to generate random 0 and 1 numbers. However I don't get the meaning for >0.5 and 1:0. I know this is supposed to be a basic question, please bear with me. Thanks!

  • KeyNotFound Exception in CSsharp

    - by C Patton
    I'm about ready to bang my head against the wall I have a class called Map which has a dictionary called tiles. class Map { public Dictionary<Location, Tile> tiles = new Dictionary<Location, Tile>(); public Size mapSize; public Map(Size size) { this.mapSize = size; } //etc... I fill this dictionary temporarily to test some things.. public void FillTemp(Dictionary<int, Item> itemInfo) { Random r = new Random(); for(int i =0; i < mapSize.Width; i++) { for(int j=0; j<mapSize.Height; j++) { Location temp = new Location(i, j, 0); int rint = r.Next(0, (itemInfo.Count - 1)); Tile t = new Tile(new Item(rint, rint)); tiles[temp] = t; } } } and in my main program code Map m = new Map(10, 10); m.FillTemp(iInfo); Tile t = m.GetTile(new Location(2, 2, 0)); //The problem line now, if I add a breakpoint in my code, I can clearly see that my instance (m) of the map class is filled with pairs via the function above, but when I try to access a value with the GetTile function: public Tile GetTile(Location location) { if(this.tiles.ContainsKey(location)) { return this.tiles[location]; } else { return null; } } it ALWAYS returns null. Again, if I view inside the Map object and find the Location key where x=2,y=2,z=0 , I clearly see the value being a Tile that FillTemp generated.. Why is it doing this? I've had no problems with a Dictionary such as this so far. I have no idea why it's returning null. and again, when debugging, I can CLEARLY see that the Map instance contains the Location key it says it does not... very frustrating. Any clues? Need any more info? Help would be greatly appreciated :)

  • How can I forcibly close a TcpListener

    - by Nissim
    I have a service which communicates through tcpListener. Problem is when the user restarts the service - an "Address already in use" exception is thrown, and the service cannot be started for a couple of minutes or so. Is there's any way of telling the system to terminate the old connection so I can open a new one? (I can't just use random ports because there is no way for the service to notify the clients what is the port, so we must depend on a predefined port)

  • Grunt: Bower for development and CDN for production - is it possible?

    - by EricC
    For development, I guess it is fine to use a plugin like https://github.com/stephenplusplus/grunt-wiredep But for production I would like to use CDN where such exists. Does it exist a Grunt plugin that goes through the bower.json file and replaces this with a CDN-link from the most popular ones (and if a component is present in more than one CDN, then pick one based on rank-setting or random or something).

  • What causes POCO proxy entities to only sometimes be created in Entity Framework 4.

    - by Kohan
    I have set up my POCOs and I have marked their public properties as virtual and I am successfully getting Proxies most of the time (95%) but randomly I am getting EF return some proxies and some non-proxies. Recycling the app pool when this happens will then fix this instance of the error and it will go away for an amount of time. Then it will re-occur in some other random (it seems) place. What can cause this sort of behaviour? Thanks, Kohan

  • JQuery Ajax Updating MySQL Database, But Not Running Success Function

    - by myrmidon16
    I am currently using the JQuery ajax function to call an exterior PHP file, in which I select and add data in a database. Once this is done, I run a success function in JavaScript. What's weird is that the database is updating successfully when ajax is called, however the success function is not running. Here is my code: <!DOCTYPE html> <head> <script type="text/javascript" src="jquery-1.6.4.js"></script> </head> <body> <div onclick="addtask();" style="width:400px; height:200px; background:#000000;"></div> <script> function addtask() { var tid = (Math.floor(Math.random() * 3)) + 1; var tsk = (Math.floor(Math.random() * 10)) + 1; if(tsk !== 1) { $.ajax({ type: "POST", url: "taskcheck.php", dataType: "json", data: {taskid:tid}, success: function(task) {alert(task.name);} }); } } </script> </body> </html> And the PHP file: session_start(); $connect = mysql_connect('x', 'x', 'x') or die('Not Connecting'); mysql_select_db('x') or die ('No Database Selected'); $task = $_REQUEST['taskid']; $uid = $_SESSION['user_id']; $q = "SELECT task_id, taskname FROM tasks WHERE task_id=" .$task. " LIMIT 1"; $gettask = mysql_fetch_assoc(mysql_query($q)); $q = "INSERT INTO user_tasks (ut_id, user_id, task_id, taskstatus, taskactive) VALUES (null, " .$uid. ", '{$gettask['task_id']}', 0, 1)"; $puttask = mysql_fetch_assoc(mysql_query($q)); $json = array( "name" => $gettask['taskname'] ); $output = json_encode($json); echo $output; Let me know if you have any questions or comments, thanks.

  • Who owns forum users or are user grabbers legal?

    - by Eugene
    Hi, I am not very strong in "legal or not" questions so I hope someone can help me here. How legal is the following: I create my forum, then choose a random existing forum (not mine), take a user from that forum (username, avatar, etc) and create an identical account at my forum. I know that this is extremely hard to prove and everything but anyway: how legal are the described actions? Thanks!

  • C++: type Length from float

    - by anon
    This is kinda like my earlier question: http://stackoverflow.com/questions/2451175/c-vector3-type-wall Except, now, I want to do this to a builtin rather then a user created type. So I want a type "Length" that behaves just like float -- except I'm going to make it's constructor explicit, so I have to explicitly construct Length objects (rather than have random conversions flying around). Basically, I'm going into the type-a-lot camp.

  • Javascript question

    - by Craig
    I am supposed to make this simple program. It produces a multiplication problem, and when the user types the correct answer, it is supposed to produce another question. Instead it goes into an infinite loop and never stops, the answer field and the button go away. Also, I am supposed to make the comment about the users answer, one of 4 different sayings. Without using Arrays how would I do that? My professor is no help, really getting aggravated as I have no where else to turn. <html> <title>HW 9.27 and 9.28</title> <head> <script type="text/javascript"> var number1; var number2; var answer3; var answer2; function problem() { number1 = Math.floor(1 + Math.random() * 9); number2 = Math.floor(1 + Math.random() * 9); document.writeln("How much is " + number1 + " times " + number2 + " ?"); answer2 = (number1 * number2); } function answer1() { var statusDiv = document.getElementById("status"); answer3 = document.getElementById("answer").value; if (answer3 != answer2) statusDiv.innerHTML = "No. Please try again"; else if (answer3 == answer2) { statusDiv.innerHTML = "Very good!"; problem(); } } problem(); </script> </head> <body> <form> <input id="answer" type="text" /> <input type="button" value="Solve!" onclick="answer1()" /> <div id ="status">Click the Solve button to Solve the problem</div> </form> </body> </html>

  • How to set custom form input field for "Price"?

    - by RodeoRamsey
    I have a basic html form that adds some data to the page using PHP. I want to make this form field a "Price" field. My html is: <input class="bids" name="comment" id="comment" tabindex="4" /> How can I fix this field so that users can't enter random letters, dollar signs, dashes, or other weird formats. I want the output to be whole dollars. Sorry I'm a complete programming moron. :)

  • Allocation of IP Address in Ad hoc systems

    - by Kasturi
    Me and my friends play Age of Empires every weekend and create an Ad-hoc network each time before playing. But each time we all get the SAME IP Address even if a new ad-hoc network is created. Is this something to do with the Game's algorithm or does the laptop remember our previous IP Address. EDIT: What is the algorithm that is used to distribute the IP Addresses? If the algorithm uses random function how come same IP addresses are being allocated.
