  • XCode 5 says I got a duplicate, which I don't

    - by GoodMove
    The point is every time I try to run a C++ code in XCode 5 (the file s "File.cpp") xcode returns this: duplicate symbol _main ld: 1 duplicate symbol for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation) And it only returns the error, when I got the following function whatever it contains: int main() { } I checked the folder, which XCode points to (where it says the duplicates are placed), but didn't find anything though. What am I supposed to do??? #include "File.h" using namespace std; void func (void){ cout << "Hello World!" << endl; }

  • Proper use of use of "cor" function in R

    - by order
    I am interested to know what a proper x (vector matrix or data frame) input looks like. I am currently using the function in two different sorts of matrices. However, I am not sure how R would interpret my data the way I intend. I will explain the types of matrix by example. Type 1 Gene1 Gene2 Gene3 sample1 sample2 Type 2 Sample1 Sample2 Sample3 gene 1 gene 2 gene 3 Are either of these formats valid x parameters? I input both of types of matrices and get some results, but without knowing whether or not this a proper use the function, these are just random numbers. Thank you for your time. I apologize that this isn't more interesting.

  • SkinId and Dynamic Control

    - by Alex
    Hi! I have some control that I add dynamically to my page: public partial class _Default : Page { protected override void CreateChildControls() { base.CreateChildControls(); var testControl = new TestControl { SkinID = "TestSkin" }; Controls.Add(testControl); } } I have the following skin file for this control: <cc:TestControl runat="server" SkinID="TestSkin" TestProperty="LALALA" /> But TestProperty is null (if control is static all works): public class TestControl : LinkButton { public string TestProperty { get; set; } protected override void OnPreRender(EventArgs e) { if (String.IsNullOrEmpty(TestProperty)) { throw new ArgumentNullException("TestProperty"); } } } Any ideas about how to fix it?

  • dynamic text in <h1> tag

    - by Ami
    what would be the impact on SEO of changing the text of the <h1> dynamically on the server side each time the web page loads? I'm not talking about changing the whole text, just part of it, for example if the header contains some fixed text (with keywords of course), and also contains the current date or time/the current number of logged on users/the count of items current in stock/whatever. how would that affect my ranking? is it bad? doesn't make a difference? thanks.

  • LINQ To SQL Dynamic Select

    - by mcass20
    Can someone show me how to indicate which columns I would like returned at run-time from a LINQ To SQL statement? I am allowing the user to select items in a checkboxlist representing the columns they would like displayed in a gridview that is bound to the results of a L2S query. I am able to dynamically generate the WHERE clause but am unable to do the same with the SELECT piece. Here is a sample: var query = from log in context.Logs select log; query = query.Where(Log => Log.Timestamp > CustomReport.ReportDateStart); query = query.Where(Log => Log.Timestamp < CustomReport.ReportDateEnd); query = query.Where(Log => Log.ProcessName == CustomReport.ProcessName); foreach (Pair filter in CustomReport.ExtColsToFilter) { sExtFilters = "<key>" + filter.First + "</key><value>" + filter.Second + "</value>"; query = query.Where(Log => Log.FormattedMessage.Contains(sExtFilters)); }

  • Is call to function object inlined?

    - by dehmann
    In the following code, Foo::add calls a function via a function object: struct Plus { inline int operator()(int x, int y) const { return x + y; } }; template<class Fct> struct Foo { Fct fct; Foo(Fct f) : fct(f) {} inline int add(int x, int y) { return fct(x,y); // same efficiency adding directly? } }; Is this the same efficiency as calling x+y directly in Foo::add? In other words, does the compiler typically directly replace fct(x,y) with the actual call, inlining the code, when compiling with optimizations enabled?

  • Dynamic Views based on view models

    - by Joe
    I have an asp.net mvc 2 app. I need to display the same page to each user. But each user has different rights to the data. IE some can see but not edit some data, some cannot edit nor see the data. Ideally data that cannot be seen nor edited is whitespace on the view. For security reasons I want my viewmodels to be sparse as possible. By that I mean if a field cannot be seen nor edited , that field should not be on the viewmodel. Obviously I can write view for each view model but that seems wasteful. So here is my idea/wishlist Can I decorate the viewmodel with attributes and hook into a pre render event of the html helpers and tell it to do &nbsp; instead??? Can I have the html helpers output &nbsp; for entries not found on the viewmodel?? or can I easily convert a view built into code then programaticlly build the markup and then put into the render engine to be processed and viewd as html on client side??

  • What is the best way to handle dynamic content_type in Sinatra

    - by lusis
    I'm currently doing the following but it feels "kludgy": module Sinatra module DynFormat def dform(data,ct) if ct == 'xml';return data.to_xml;end if ct == 'json';return data.to_json;end end end helpers DynFormat end My goal is to plan ahead. Right now we're only working with XML for this particular web service but we want to move over to JSON as soon as all the components in our stack support it. Here's a sample route: get '/api/people/named/:name/:format' do format = params[:format] h = {'xml' => 'text/xml','json' => 'application/json'} content_type h[format], :charset => 'utf-8' person = params[:name] salesperson = Salespeople.find(:all, :conditions => ['name LIKE ?', "%#{person}%"]) "#{dform(salesperson,format)}" end It just feels like I'm not doing it the best way possible.

Any idea why?

  • Using jquery to disable function untill all selects are changed

    - by richbyte
    I am using a javascript function (F) (jquery )which uses 3 select values selected by the user to calculates a value - R(result) R is a number ranging from (1 through 9), (11) and (22); I need 2 extra steps one before the calculation and one after. a. Before calculation takes place: Make sure all three select values are changed before function(F) takes place. If not prompt the user with a notice ( create dom element/ I am using jquery) b. After the value R is calculated show an element corresponding to the result e.g. if R is 1 show an element ( a predetermined "link" element corresponding to each result value) thanks a lot.

  • Notepad++ or other application to replace string with numeric function

    - by user38963
    Hello. I am using Notepad++ and attempting to replace all numeric strings within a specific tag (xxxxof my XML document with a new string which has been modified by a specific variable. Here's an example (please remove the space between < and start): < start501234< /start round(501234 * 0.9) = 451111 < start451111< /start Is there a way to automatically find all numeric values within the start tag and do replace it by that same value multiplied by 0.9? I don't have to use Notepad++ if there's another tool that can do this. Thanks!

  • Check for element equality in an animation function.

    - by Zardoz
    I have the the below code and would expect that in the first pass of the fadeTo function "yes" would be printed as those first two console logs tell me it is the same element. But it doesn't recognize them as equal. What do I miss here? var tds = self.element.find("td:nth-child(" + (columnIndex + 1) + ")"); tds.fadeTo(options.columnFadeOutTime, 0, function() { window.console.log(tds.first()); window.console.log($(this)); if ($(this) == tds.first()) { window.console.log("yes"); } else { window.console.log("no"); } }

  • Wordpress and Dynamic Programming Php

    - by user1675146
    I have geography pages for two types of business listings. Each page goes from state, county, city, but I need to have the same geography shared between two types of business. My two business types are dentist and chiropractors. I am trying to have a permalink structure like this: enter code here xyz.com/dentist/alabama enter code here xyz.com/dentist/alabama/polk-county/ enter code here xyz.com/chiropractors/alabama/ enter code here xyz.com/chiropractors/alabama/polk-county/ I originally was going to load the geography as pages and subpages, but with that method I cannot get the permalink separated by the type chiropractor and dentist. So now I have created a custom post type one for chiropractor and one for dentist which give me the permalink xyz.com/dentist and xyz.com/chiropractor. My question is now how to handle my category geography page. I was wondering if in wordpress it is possible to create a shell page such as xyz.com/dentist/[state]/ and then through php dynamically build a page for each state? So where it shows [state] it will be replaced with the actual state such as alabama, california etc when that specific page is viewed. But the shell page is just 1 page in the database. If so could someone give me a basic explanation on how to instruct a programmer to do this? Thank you.

  • MPI - passing function as a parameter

    - by Hmyzak
    Hi, is there any how how to pass function as a parameter when starting program in C? I am implementing app for integral aproximation, and all I need is to type a function I want to work with, when starting app. I tried (e.g.) 2/(2+2*x), but I only get back "2". When I write to application directly, there is no problem. Is there any simple way of getting this? Maybe redistribute it to more parametres? Like app.c number number*x number *x*x number *x*x*x... ? Thanks
