  • Is it possible to use an incremental value within a variable name whilst declaring it within a loop?

    - by Jack
    Hi, I'm creating function which will read different XML files each time that will contain different amounts of the same nodes. I have already created a loop which stores the ID of each node into an array, and now I want to create variables for each array member which store attributes of the node with each ID. Because the number of nodes will be different for every XML document my function reads, I cannot manually assign variables for the attributes of each node ID not knowing how many to assign, so I have created a loop which runs specific to the number of items I have stored in the array. Inside this loop I was hoping to have something like: for (i=0; i<array.length; i++) { var ID + i + width = exampleheight var ID + i + height = exampleheight } I know this doesn't work, but was trying to outline what I am looking to find out. Is it possible to use some kind of variable or random number when declaring a variable?

  • Options for storing large text blobs in/with an SQL database?

    - by kdt
    Hi, I have some large volumes of text (log files) which may be very large (up to gigabytes). They are associated with entities which I'm storing in a database, and I'm trying to figure out whether I should store them within the SQL database, or in external files. It seems like in-database storage may be limited to 4GB for LONGTEXT fields in MySQL, and presumably other DBs have similar limits. Also, storing in the database presumably precludes any kind of seeking when viewing this data -- I'd have to load the full length of the data to render any part of it, right? So it seems like I'm leaning towards storing this data out-of-DB: are my misgivings about storing large blobs in the database valid, and if I'm going to store them out of the database then are there any frameworks/libraries to help with that? (I'm working in python but am interested in technologies in other languages too)

  • iOS Development: Why isn't my try block catching the exception?

    - by BeachRunnerJoe
    Hi. I have an exception being thrown in my code, but when I wrap it in an try/catch block, it doesn't get caught. The NSLog statement is never called in the catch block. Here's the code... NSInteger quoteLength; [data getBytes:(void *)&quoteLength range:NSMakeRange(sizeof(messageType), sizeof(quoteLength))]; @try { //Debugger stack trace shows an NSException being thrown on this statement NSData *stringData = [data subdataWithRange:NSMakeRange(sizeof(messageType) + sizeof(quoteLength), [data length])]; NSString *quote = [[NSString alloc] initWithData:stringData encoding:NSUTF8StringEncoding]; NSLog(@"received quote: %@",quote); [quote release]; } @catch (NSException * e) { NSLog(@"Exception Raised: %@", [e reason]); } Why doesn't it get caught? Thanks so much!

  • How Do Sockets Work in C?

    - by kaybenleroll
    I am a bit confused about socket programming in C. You create a socket, bind it to an interface and an IP address and get it to listen. I found a couple of web resources on that, and understood it fine. In particular, I found an article Network programming under Unix systems to be very informative. What confuses me is the timing of data arriving on the socket. How can you tell when packets arrive, and how big the packet is, do you have to do all the heavy lifting yourself? My basic assumption here is that packets can be of variable length, so once binary data starts appearing down the socket, how do you begin to construct packets from that?

  • How to determine on which file system a file was created in Java

    - by rafrafUk
    Hi Everyone! I get files in different formats coming from different systems that I need to import into our database. Part of the import process it to check the line length to make sure the format is correct. We seem to be having issues with files coming from UNIX systems where one character is added. I suspect this is due to the return carriage being encoded differently on UNIX and windows platform. Is there a way to detect on which file system a file was created, other than checking the last character on the line? Or maybe a way of reading the files as text and not binary which I suspect is the issue? Thanks Guys !

  • Heap property of this array

    - by davit-datuashvili
    From programming pearls, it is known that array[1...n] has heap property if for all 2<=i<=n x[i/2]<=x[i]. Here is my code: import java.math.*; public class Heap { public static void main(String[]args){ int x[]=new int[]{12,20,15,29,23,17,22,35,40,26,51,19}; int i=1; while (i<x.length) { if (x[Math.round(i/2)]<=x[i]) System.out.println("heap"); i++; } System.out.println("not heap"); } } Here I used Math.round because 4/2 and 5/2 is same and =2. When I compile this code it shows me at last line that it is not heap. Maybe because the index starts from 1 and we don't pay attention to index 0, yes?

  • C++: Why does space always terminate a string when read?

    - by Nullw0rm
    Using type std::string to accept a sentence, for practise (I haven't worked with strings in C++ much) I'm checking if a character is a vowel or not. I got this: for(i = 0; i <= analyse.length(); i++) { if(analyse[i] == 'a' || analyse[i] == 'e' [..etc..]) { ...vowels++; } else { ... ...consenents++; } This works fine if the string is all one word, but the second I add a space (IE: aeio aatest) it will only count the first block and count the space as a consenent, and quit reading the sentence (exiting the for loop or something). Does a space count as no character == null? Or some oddity with std::string?, It would be helpful to know why that is happening!

  • How can I apply indexer to Dictionary VALUES (C#3.0)

    - by Newbie
    I have done a program string[] arrExposureValues = stock.ExposureCollection[dt] .Values.ToArray(); for(int i=0;i<arrExposureValues .length;i++) Console.WriteLine(arrExposureValues[i]); Nothing wrong and works fine. But is it possible to do something like the below for(int i=0;i<stock.ExposureCollection[dt].Count;i++) Console.WriteLine(stock.ExposureCollection[dt].Values[i]); This is just for my sake of knowledge (Basically trying to accomplish the same in one line). Note: ExposureCollection is a dictionary object Dictionary<DateTime, Dictionary<string, string>> First of all I have the doubt if it is at all possible! I am using C#3.0. Thanks.

  • Generate all the ways to intersperse a list of lists, keeping each list in order.

    - by dreeves
    Given a list of lists like this [[1,2,3],[a,b,c,d],[x,y]] generate all permutations of the flattened list, [1,2,3,a,b,c,d,x,y], such that the elements of each sublist occur in the same order. For example, this one is okay [a,1,b,2,x,y,3,c,d] but this one is not [y,1,2,3,a,b,c,x,d] because y must occur after x, that being how x and y are ordered in the original sublist. I believe the number of such lists is determined by the multinomial coefficient. I.e., if there are k sublists, n_i is the length of the ith sublist, and n is the sum of the n_i's then the number of such permutations is n!/(n_i! * ... * n_k!). The question is how to generate those sublists. Pseudocode is great. An actual implementation in your language of choice is even better!

  • Removing first two elements of a string array in C

    - by sandeep p
    How can I remove first two elements of a string array? I have a code which is something like this. char *x[10]; .............. .............. .............. char *event[20]; event[0]=strtok(x[i]," "); event[1]=strtok(NULL," "); event[2]=strtok(NULL," "); event[3]=strtok(NULL," "); event[4]=strtok(NULL," "); event[5]=strtok(NULL," "); for(i=2;i<length;i++) { strcpy(event[i-2],event[i]); } I observed that only event[0] has proper values. I printed the contents of event[][] before for loop and it displays correctly. Could you please tell me why this is wrong? and a possible solution?

  • How to I preload images where it actually forces the images to load before continuing (html/javascri

    - by Mr. Flibble
    I want to preload images but ensure they are loaded before continuing. How can I do this? The following does not work as it sends off the load request only, but doesn't wait till the image is loaded. So it is possible that the image isn't loaded when requested soon after. jQuery.preloadImages = function () { for (var i = 0; i < arguments.length; i++) { jQuery("<img>").attr("src", arguments[i]); } } $.preloadImages("img1.jpg","img2.jpg");

  • Reporting sanitized user input to the user via AJAX

    - by JimBo
    I am writing some code to give live feedback to the user on the validation of a form using AJAX. I have got it checking length and if the field is empty. Now I want it to sanitize the users input and if the sanatized input differs from the users original input then tell them which characters are not allowed. The code I have written so far works except some characters most notably a '£' symbol result in no response. I think it relates to json_encode and its encoding. Here is the code: $user_input = 'asdfsfs£'; $strip_array = str_split(strip($user_input)); $orig_array = str_split($user_input); $diff_array = array_diff($orig_array,$strip_array); $diff_str = implode(', ',$diff_array); $final = json_encode($diff_str); function strip($input){return htmlentities(strip_tags($input),ENT_QUOTES);} Hope someone can figure out a solution.

  • Should filters write to the response during or after filtering?

    - by Mark
    I have a filter which processes generated HTML and rewrites certain elements. For example, it adds class attributes to some anchors. Finally, it writes the processed HTML to the response (a subclass of HttpServletResponseWrapper). Naturally, this means that the processed HTML is a different length after it has passed through the filter. I can see two ways of approaching this. One is to iterate over the HTML, using a StringBuilder to build up the processed HTML, and write the processed HTML to the response once all filtering is complete. The other is to iterate over the HTML but to write it to the response as soon as each element has been processed. Which is the better way for this operation, or is there another option which would be preferable? I am looking to minimise temporary memory usage primarily.

  • c++ strings and file input

    - by Dalton Conley
    Ok, its been a while since I've done any file input or string manipulation but what I'm attempting to do is as follows while(infile >> word) { for(int i = 0; i < word.length(); i++) { if(word[i] == '\n') { cout << "Found a new line" << endl; lineNumber++; } if(!isalpha(word[i])) { word.erase(i); } if(islower(word[i])) word[i] = toupper(word[i]); } } Now I assume this is not working because skips the new line character?? If so, whats a better way to do this.

  • PHP cURL: get headers only from post

    - by Stewart
    There ought to be a way of sending a post request and getting back just the headers. $ch = curl_init('http://www.stackoverflow.com/'); curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_NOBODY, true); doesn't work, because all setting CURLOPT_NOBODY does is to change the request method to HEAD, thereby overriding CURLOPT_POST. I could just leave the last of these lines out and only process the headers, but is there a more efficient way? It's also odd that there doesn't seem to be a way in cURL to truncate the received content to a specified length as there is with file_get_contents.

  • How can I *prevent* Apache2 from setting the Content-Type header?

    - by Norm
    I have a CGI script that prints the following on stdout: print "Status: 302 Redirect\n"; print "Server: Apache-Coyote/1.1\n"; print "Location: $redirect\n"; print "Content-Length: 0\n"; print "Date: $date\n\n"; Where $redirect and $date are reasonable values. What Apache2 actually sends also includes a Content-Type: header (text/plain). I've commented out the DefaultType in the server configuration file. I'm trying to debug a downstream problem that arises when no Content-Type: header is sent. So what magic incantation do I have to perform to prevent Apache2 from adding the content type header?

  • Patterns for avoiding jQuery silent fails

    - by Matias
    Is there any good practice to avoid your jQuery code silently fail? For example: $('.this #is:my(complexSelector)').doSomething(); I know that every time this line get executed, the selector is intended to match at least one element, or certain amount of elements. Is there any standard or good way to validate that? I thought about something like this: var $matchedElements = $('.this #is:my(complexSelector)'); if ($matchedElements.length < 0) throw 'No matched elements'; $matchedElements.doSomething(); Also I think unit testing would be a valid option instead of messing the code. My question may be silly, but I wonder whether there is a better option than the things that I'm currently doing or not. Also, maybe I'm in the wrong way checking if any element match my selector. However, as the page continues growing, the selectors could stop matching some elements and pieces of functionality could stop working inadvertently.

  • Pick Random String From Array

    - by atrljoe
    How do I go about picking a random string from my array but not picking the same one twice. string[] names = { "image1.png", "image2.png", "image3.png", "image4.png", "image5.png" }; Is this possible? I was thinking about using return strings[random.Next(strings.Length)]; But this has the possibility of returning the same string twice. Or am I wrong about this? Should I be using something else like a List to accomplish this. Any feedback is welcome.

  • Better alternatives to know whether a control is valid in javascript?

    - by Anthony
    I want to know whether a control is valid or not in javascript. Is there a direct client side API available in Asp.Net which can tell me whether a control is valid or not? Eg. If I have 2 validators attached to a textbox, I need a function that can tell me whether the textbox is valid or not. If even 1 validator is not valid then it should return false. I can't seem to find a function that can give me this. Here is a little helper that I wrote which does the job but is inefficient: function isControlValid(control) { for (i = 0; i < Page_Validators.length; i++) { var validator = Page_Validators[i]; var controlId = validator.controltovalidate; if ($(control).attr('id') == controlId && validator.isvalid == false) { return false; } } return true; } Anybody has any better alternatives?
