  • Ruby string encoding problem

    - by John Prideaux
    I've looked at the other ruby/encoding related posts but haven't been able to figure out why the following is not working. Likely just because I'm dense, but here's the situation. Using Ruby 1.9 on windows. I have a set of CSV files that need some data appended to the end of each line. Whenever I run my script, the appended characters are gibberish. The input text appears to be IBM437 encoding, whereas my string I'm appending starts as US-ASCII. Nothing I've tried with respect to forcing encoding on the input strings or the append string seems to change the resultant output. I'm stumped. The current encoding version is simply the last that I tried. def append_salesperson(txt, salesperson) if txt.length > 2 return txt.chomp.force_encoding('US-ASCII') + %(, "", "", "#{salesperson}") end end salespeople = Hash[ "fname", "Record Manager"] outfile = File.open("ActData.csv", "w:US-ASCII") salespeople.each do | filename, recordManager | infile = File.open("#{filename}.txt") infile.each do |line| outfile.puts append_salesperson(line, recordManager) end infile.close end outfile.close

    - by helloman
    I am having trouble starting out this program, I am suppose to write a program that will create an ArrayList, asking the user for 10 numbers. Then this will be put into the Array.

  • JS - Why is this hidden div not showing in IE?

    - by Dodi300
    Hello. I've made a page which should show a div when the user clicks on a input text box. The div will contain more information about the required input, etc. The page works fine on FireFox and the div shows, but when using IE the div just doesn't show. It seems like I've tried everything and nothing has worked so far. This is the page. Maybe you could look at the source and see what I'm doing wrong? If you need me to upload the source as a text file, I can do that. Thanks for the help!

  • pass by reference but reference to data and not to variable

    - by dorelal
    This is psesudo code. In what programming language this is possible ? def lab(input) input = ['90'] end x = ['80'] lab(x) puts x #=> value of x has changed from ['80'] to ['90] I have written this in ruby but in ruby I get the final x value of 80 because ruby is pass-by-reference. However what is passed is the reference to the data held by x and not pointer to x itself same is true in JavaScript. So I am wondering if there is any programming language where the following is true.

  • How to find the formula of best case and worst case of my algorithm?

    - by rachel7660
    I was given a task. Write an algorithm so that, the input of 2 lists of data, will have at least one in common. So, this is my algorithm: (I write the code in php) $arrayA = array('5', '6', '1', '2', '7'); $arrayB = array('9', '2', '1', '8', '3'); $arrayC = array(); foreach($arrayA as $val){ if(in_array($val, $arrayB)){ array_push($arrayC, $val); } } Thats my own algo, not sure if its a good one. So, based on my algorithm, how to find the formula of best case and worst case (big O)? Note: Please do let me know, if my algorithm is wrong. My goal is " input of 2 lists of data, will have at least one in common."

  • python dictionary conversion from string?

    - by shahjapan
    if I've string like "{ partner_name = test_partner}" OR " { partner_name : test_partner } its an example string will be very complex with several special characters included like =, [ , ] , { , } what will be the best way to convert it into a python object - so I can process it I tried with eval but it requires " ' " for string, but how can we add this special character \' before starting and ending of every word, I tried regular express re.findal('\w+') but it fails when my string contains ' _ ' or like characters as it will separate the string by ' _ ' Object of this question is my application needs, user friendly language as input - and I thought Json Dict will be good - but user is lazzy to put " ' " before and after of each string... then I thought for yaml but its also complex, if anybody can suggest better user friendly input which I use as python object - then please help me out.

  • Elegant way to reverse order Formtastic nested objects?

    - by stephan.com
    I'm presenting a list of items to the user with a field for a new item, like this: - current_user.tasks.build - semantic_form_for current_user do |f| - f.semantic_fields_for :tasks do |t| - t.inputs do = t.input :_destroy, :as => :boolean, :label => '' - if t.object.new_record? = t.input :name, :label => false - else = t.object.name Which looks lovely and works like a charm. My only problem is I want the new record at the TOP of the list, not the bottom. Is there an elegant and easy way to do this, or am I going to have to do the new element separately, or loop through the list manually?

  • How to test Text Search accuracy and efficiency?

    - by DEN
    I have created a web application. One of the feature is text search which perform the boolean operator ( NOT, AND, OR) as well. However, I have no idea on calculating the search's accuracy and efficiency. For example: 1 . Probe identification system for a measurement instrument 2 . Pulse-based impedance measurement instrument 3 . Millimeter with filtered measurement mode when the user key in will return the result as below input :measurement instrument Result: 1,2 input : measurement OR instrument NOT milimeter Result: 1,2,3 so, i have no idea on what issue and what algorithm to calculate on the accuracy and efficiency of the text search.. anyone have any idea on that?

  • Where does ASP.Net get its rendered IDs from?

    - by NeilD
    Hi, I've inherited a project with some nasty JavaScript that depends on hard coded object ids. i.e. There are lots of places where it does things like this var magazine = document.getElementById('repModuleDisplay__ctl3_chkCats_0'); When the page renders in my UAT environment, the HTML looks like this, and everything works OK. <input id="repModuleDisplay__ctl3_chkCats_0" type="checkbox" name="repModuleDisplay:_ctl3:chkCats:0" ... etc However, when I put it on my Production environment, the HTML is suddenly rending like this: <input id="repModuleDisplay_ctl03_chkCats_0" type="checkbox" name="repModuleDisplay$ctl03$chkCats$0" ... etc The difference in ids means that the JavaScript can't find the Element, and fails. In an ideal world, I'd scrap the buggy JavaScript and do it again properly, but for a quick fix, I'd like to know what is causing the difference in rendering between the two environments. Does anyone have any ideas? Thanks, Neil

  • jquery attribute indexOf

    - by Victor
    When I am getting at an attribute onclick of custom(Reporting Services) checkbox it gives me correct result. However when I am trying to use indexOf on that result it says "Object doesn't support this property or method", i.e. this is fine, gives me a long string $('input[id*=CustomCheckBox]').click(function() { alert( $(this).attr("onclick") ); }); But this gives an error(object doesn't support this property or method): $('input[id*=CustomCheckBox]').click(function() { if ($(this).attr("onclick").indexOf("SomeString") > -1 ) { //do some processing here } } What would I need to modify so that indexOf is working properly?

  • jQuery - search for previous selector relative to current

    - by Thomas Slater
    I have a form with 3 sections in it. Each section has a dedicated div for fairly long contextual help messages regarding the input that has focus. My question is, if I give each of these help divs a class of "form-tip" and each input that has a tip the class "has-tip", how can I get the tip to always show up in the previous "form-tip" div? Something like: $('.has-tip').each(focus(function() { var tip = $(this).attr('title'); // Find most recent $('.form-tip') in the DOM and populate it with tip })); I hope that makes sense... Thanks for any help.

  • jQuery slider onChange auto submit form

    - by bikey77
    I'm using a jQuery slider as a price range selector in a form. I'd like to have the form submit automatically when one of the values has been changed. I used a couple of examples I found on SO but they didn't work with my code. <form action="itemlist.php" method="post" enctype="application/x-www-form-urlencoded" name="priceform" id="priceform" target="_self"> <div id="slider-holder"> Prices: From <span id="pricefromlabel">100 &#8364;</span> To <span id="pricetolabel">500 &#8364;</span> <input type="hidden" id="pricefrom" name="pricefrom" value="100" /> <input type="hidden" id="priceto" name="priceto" value="500" /> <div id="slider-range"></div> <input name="Search" type="submit" value="Search" /> </div> </form> This is the code that displays the values of the slider and updates 2 hidden form fields I use to store the prices in order to submit: <script> $(function() { $("#slider-range" ).slider({ range: true, min: 0, max: 1000, values: [ <?=$minprice?>, <?=$maxprice?> ], start: function (event, ui) { event.stopPropagation(); }, slide: function( event, ui ) { $( "#pricefrom" ).val(ui.values[0]); $( "#priceto" ).val(ui.values[1]); $( "#pricefromlabel" ).html(ui.values[0] + ' &euro;'); $( "#pricetolabel" ).html(ui.values[1] + ' &euro;'); } }); return false; }); </script> I've tried adding this code as well as an data-autosubmit="true" attribute to the div but no result. $(function() { $('[data-autosubmit="true"]').change(function() { parentForm = $(this).('#priceform'); clearTimeout(submitTimeout); submitTimeout = setTimeout(function() { parentForm.submit() }, 100); }); I've also tried adding a $.post() event to the slider but I'm not very good with jQuery so I'm probably doing it wrong. Any help will be appreciated.

  • Using scanf() in C++ programs is faster than using cin ?

    - by zeroDivisible
    Hello, I don't know if this is true, but when I was reading FAQ on one of the problem providing sites, I found something, that poke my attention: Check your input/output methods. In C++, using cin and cout is too slow. Use these, and you will guarantee not being able to solve any problem with a decent amount of input or output. Use printf and scanf instead. Can someone please clarify this? Is really using scanf() in C++ programs faster than using cin something ? If yes, that is it a good practice to use it in C++ programs? I thought that it was C specific, though I am just learning C++...

  • What is the time taken by java to call a method in another package?

    - by satish
    I have an assignment where i need to do feasibility study on two of my approaches and find optimized one. There are two packages A and B User input is gathered in A and then sent to B for execution. Now my approaches are 1. Call B methods from package A one by one. 2. Create a common method in B and send all the input as parameters. Which is feasible and best one, I know 2 is good in terms of code optimization and less number of calls. But, I want to understand what will be the execution time difference in above approaches How much time does java take to call method in another package? Is there any default value like x nano seconds or y milli seconds. Based on the time taken I can choose the appropiate one. Thanks

  • Is there a way to set up a Linux pipe to non-buffering or line-buffering?

    - by ern0
    My program is controlling an external application on Linux, passing in input commands via a pipe to the external applications stdin, and reading output result via a pipe from the external applications stdout. The problem is that writes to pipes are buffered by block, and not by line, and therefore delays occur before my app receives data output by the external application. The external application cannot be altered to add explicit fflush() calls. When I set the external application to /bin/cat -n (it echoes back the input, with line numbers added), it works correctly, it seems, cat flushes after each line. The only way to force the external application to flush, is sending exit command to it; as it receives the command, it flushes, and all the answers appears on the stdout, just before exiting. I'm pretty sure, that Unix pipes are appropiate solution for that kind of interprocess communication (pseudo server-client), but maybe I'm wrong. (I've just copied some text from a similar question: Force another program's standard output to be unbuffered using Python)

  • Retrieving values from Env in mod_esi or webtools

    - by williamstw
    A complete noob question, but how exactly do I get values (e.g. path_info) from inside the callback? From the docs, I thought it was a list of tuples, which I thought would make it accessible via lists:keyfind, but I've had no luck. So far, all the examples I've found only show how to print everything with io_lib but not how to access the values by key... Thanks, --tim The docs: Module:Function(SessionID, Env, Input)- _ Types SessionID = term() Env = [EnvironmentDirectives] ++ ParsedHeader EnvironmentDirectives = {Key, Value} Key = query_string | content_length | server_software | gateway_interface | server_protocol | server_port | request_method | remote_addr | script_name. <v>Input = string()

  • Url Rewriting with Querystrings

    - by Alon
    In IIS 7.5, I'm trying to rewrite a Url such as /about to /content.asp?p=about, with support for QueryString-s, so if the orginal Url was /about?x=y, it should rewrite to /content.asp?p=about&x=y. The basic rewriting is now working, but when I'm trying to add a QueryString it doesn't work. Tried both /about?x=y and /about&x=y. My current rule: <rule name="RewriteUserFriendlyURL1" stopProcessing="false"> <match url="^([^/]+)/?$" /> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> </conditions> <action type="Rewrite" url="content.asp?p={R:1}" /> </rule> How can I fix this? Thank you.

  • How does a Java Arraylist contains() method evaluate objects?

    - by mvid
    Say i create one object and add it to my ArrayList. If I then create another object with exactly the same constructor input, will the contain() method evaluate the two objects to be the same? Assume the constructor doesn't do anything funny with the input, and the variables stored in both objects are identical. ArrayList<Thing> basket = new ArrayList<Thing>(); Thing thing = new Thing(100); basket.add(thing); Thing another = new Thing(100); basket.contains(another); // true or false?
