  • Program always returns binary '>>' : no operator found which takes a left-hand operand of type error

    - by Tom Ward
    So I've been set a task to create a temperature converter in C++ using this equation: Celsius = (5/9)*(Fahrenheit – 32) and so far I've come up with this (I've cut out the 10 lines worth of comments from the start so the code posted begins on line 11, if that makes any sense) #include <iostream> #include <string> #include <iomanip> #include <cmath> using namespace std; int main () { float celsius; float farenheit; std::cout << "**************************" << endl; std::cout << "*4001COMP-Lab5-Question 1*" << endl; std::cout << "**************************" << endl << endl; std::cout << "Please enter a temperature in farenheit: "; std::cin >> farenheit >> endl; std::cout << "Temperature (farenheit): " << endl; std::cout << "Temperature (celsius): " << celsius << endl; std::cin.get(); return 0; } Everytime I try to run this program I get a heap of errors with this one appearing every time: 1m:\visual studio 2010\projects\week 5\week 5\main.cpp(26): error C2678: binary '' : no operator found which takes a left-hand operand of type 'std::basic_istream<_Elem,_Traits' (or there is no acceptable conversion) I've tried everything I can think of to get rid of this error but it reappears every time, any idea on how to fix this?

  • Where to start with the development of first database driven Web App (long question)?

    - by Ryan
    Hi all, I've decided to develop a database driven web app, but I'm not sure where to start. The end goal of the project is three-fold: 1) to learn new technologies and practices, 2) deliver an unsolicited demo to management that would show how information that the company stores as office documents spread across a cumbersome network folder structure can be consolidated and made easier to access and maintain and 3) show my co-workers how Test Drive Development and prototyping via class diagrams can be very useful and reduces future maintenance headaches. I think this ends up being a basic CMS to which I have generated a set of features, see below. 1) Create a database to store the site structure (organized as a tree with a 'project group'-project structure). 2) Pull the site structure from the database and display as a tree using basic front end technologies. 3) Add administrator privileges/tools for modifying the site structure. 4) Auto create required sub pages* when an admin adds a new project. 4.1) There will be several sub pages under each project and the content for each sub page is different. 5) add user privileges for assigning read and write privileges to sub pages. What I would like to do is use Test Driven Development and class diagramming as part of my process for developing this project. My problem; I'm not sure where to start. I have read on Unit Testing and UML, but never used them in practice. Also, having never worked with databases before, how to I incorporate these items into the models and test units? Thank you all in advance for your expertise.

  • Getting HTMLUnknownElement with jQuery.find() and an XML Document

    - by Tom
    I'm attempting to load up an XML document (specifically an RSS feed) via an Ajax request, parse it, and insert some information based on said feed into my page. The code works fine in Firefox, Opera, Chrome, and Safari, but not IE7. Go figure. After doing some initial debugging, I've found that the XML string is being retrieved via the request, and the specific node type I'm getting when trying to parse nodes out of the document is HTMLUnknownElement. Here's the relevant code: $.get('feed.php', function(oXmlDoc) { var titles = $(oXmlDoc).find('title'); var dates = $(oXmlDoc).find('pubDate'); for(var i = 0; i < 5; i++) { parseNodes(titles[i].firstChild.nodeValue, dates[i].firstChild.nodeValue)); } }); The parseNodes function is never actually being hit because IE cannot access firstChild and, consequently, nodeValue. Thanks in advance for any ideas and/or suggestions on how to address this.

  • Why does my perl script return a zero return code when I explicitly call exit with a non-zero parame

    - by Tom Duckering
    I have a perl script which calls another script. The perl script should be propagating the script's return code but seems to be returning zero to its caller (a Java application) desipte the explicit call to exit $scriptReturnCode. It's probably something dumb since I'm by no means a perl expert. Code and output as follows (I realise that <=> could/should be != but that's what I have): print "INFO: Calling ${scriptDirectory}/${script} ${args}" $scriptReturnCode = system("${scriptDirectory}/${script} ${args}"); if ( $scriptReturnCode <=> 0 ) { print "ERROR: The script returned $scriptReturnCode\n"; exit $scriptReturnCode; } else { print "INFO: The script returned $scriptReturnCode.\n"; exit 0; } The output I have from my Java is: 20/04/2010 14:40:01 - INFO: Calling /path/to/script/script.ksh arg1 arg2 20/04/2010 14:40:01 - Could not find installer files <= this is from the script.ksh 20/04/2010 14:40:01 - ERROR: The script returned 256 20/04/2010 14:40:01 - Command Finished. Exit Code: 0 <= this is the Java app.

  • hunting maven dependencies

    - by Tom
    I want to start using maven in code I distribute but I can't find an efficient way to work with dependencies. Every new dependency takes me far too long to add. As a simple example, I need to add Tomcat for compilation. Do I really have to manually trawl the repo in my browser to find the group-id, artifact-id and version number? In every case it seems easier to find the non-maven downloads. I hope I've missed something obvious.

  • Stackoverflow interesting tags

    - by Tom
    So, that's how works Interesting Tags: I add into them my interested tags like php, mysql, jquery and so on. Then, if any of questions has the same tags as mine it makes background orange. I understand how to use jquery to do that (there were related questions to that), but without mysql it can't be done. Now, here is a question. How is it done? I imagine like that: There is a row in mysql for every member, let's call it "interested_tags". After I write and submit my tag through input, it is being written in a row "interested_tags". Then, the main page has a query which shows all answers and it always checks answer's with mine tags with strpos like this if(strpos($question_tags, $my_tags) === true) {        //and here will be made background orange } Am I thinking right or is there any way to do it?

  • Static member variable containing object instances

    - by tom
    I have the following: function Preferences() { } Preferences.players = { 'player1': new Player() } players is a static member variable of Preferences and I'm trying to make it an object containing an instance of a Player. However, it doesn't appear to let me do this. It seems like it will allow me to define players if I make it a non-static member variable however. Like so: function Preferences() { var players = { 'player1' : new Player() } } Is it possible to create a static member variable containing instances of an object in JS?

  • PHP include(): File size & performance

    - by Tom
    An inexperienced PHP question: I've got a PHP script file that I need to include on different pages lots of times in lots of places. I have the option of either breaking the included file down into several smaller files and include these on a as-needed basis... OR ... I could just keep it all together in a single PHP file. I'm wondering if there's any performance impact of using a larger vs. smaller file for include() in this context? For example, is there any performance difference between a 200KB file and a 20KB file? Thank you.

  • Google Chrome forgetting registration cookie immediately

    - by Ryan Giglio
    I'm having trouble with cookies on my site's registration form. When a user creates an account, PHP sets one cookie with their user id, and one cookie with a hash containing their user agent and a few other things. Both of these cookies are set to expire in an hour. This is the code that sets the cookie after creating your account $registerHash = hash( "sha512", $_SERVER['HTTP_USER_AGENT'] . $_SERVER['HTTP_HOST'] . $_SERVER['DOCUMENT_ROOT'] ); setcookie("register_user_id", $newUserID, time() + 7200, "/"); setcookie("register_hash", $registerHash, time() + 7200, "/"); The next page is a confirmation page which sends an email and then optionally lets the user go on to fill out more account information. If the user goes on to fill out more, it uses the cookie to know what account to save it to. It works correctly in Firefox and IE, but in Chrome the cookie is forgotten as soon as you go to the next page. The cookie simply doesn't exist. You can see the problem here: http://crewinyourcode.com/register/paid/ If you use Chrome, you will get a registration timeout error as soon as you try to advance past the confirmation page. However on Firefox it works fine.

  • How do I change the name of an application tab?

    - by Tom Rom
    I'm working on a facebook page for a client and with the new profiles pages starting to roll out I've come across an issue with the name of the app I created. The original profiles which most of you will see here - http://www.facebook.com/DrMartyBecker says "Welcome" as the tab name. On the new profile pages the tab says 'drMARTY', I can't find the place where I can modify the name. So i was wondering if there was a way to change this and where. Thanks for the help!

  • Ordering z-indexes in an array

    - by Tom Gullen
    I have an array which looks something along the lines of resourceData[0][0] = "pic1.jpg"; resourceData[0][1] = 5; resourceData[1][0] = "pic2.jpg"; resourceData[1][1] = 2; resourceData[2][0] = "pic3.jpg"; resourceData[2][1] = 900; resourceData[3][0] = "pic4.jpg"; resourceData[3][1] = 1; The numeric represents the z-index of the image. Minimum z-index value is 1. Maximum (not really important) is 2000. I have all the rendering and setting z-indexes done fine. My question is, I want to have four functions: // Brings image to z front function bringToFront(resourceIndex) { // Set z-index to max + 1 resourceData[resourceIndex][1] = getBiggestZindex() + 1; // Change CSS property of image to bring to front $('#imgD' + resourceIndex).css("z-index", resourceData[resourceIndex][1]); } function bringUpOne(resourceIndex) { } function bringDownOne(resourceIndex) { } // Send to back z function sendToBack(resourceIndex) { } So given then index [3] (900 z): If we send it to the back, it will take the value 1, and [3] will have to go to 2, but that conflicts with [1] who has a 2 z-index so they need to go to three etc. Is there an easy programatical way of doing this because as soon as I start doing this it's going to get messy. It's important that the indexes of the array don't change. We can't sort the array unfortunately due to design. Update Thanks for answers, I'll post the functions here once they are written incase anyone comes across this in the future (note this code has zindex listed in [6]) // Send to back z function sendToBack(resourceIndex) { resourceData[resourceIndex][6] = 1; $('#imgD' + resourceIndex).css("z-index", 1); for (i = 0; i < resourceData.length; i++) { if (i != resourceIndex) { resourceData[i][6]++; $('#imgD' + i).css("z-index", resourceData[i][6]); } } }

  • Using arrays in Jquery

    - by Tom
    Here is a code: <input type="button" id="array[1]" value="Value1" /> <input type="button" id="array[2]" value="Value2" /> <input type="button" id="array[3]" value="Value3" /> And I want to do something like that: $('#array').click(function() { id = this.id; $.ajax({ here goes type, url, data and else }); }) I want to id add array's number. For example, if I click button where id is array[3] so id gets value of 3 in Jquery's function. Hope you got what I mean.

  • Why the generated key size is not constant?

    - by Tom Brito
    The following code prints randomly 634, 635, 636, each time I run it. Why its not constant? public static void main(String[] args) throws Exception { KeyPairGenerator keyPairGen = KeyPairGenerator.getInstance("RSA", "BC"); keyPairGen.initialize(1024); RsaKeyPair keyPair = new RsaKeyPair(keyPairGen.generateKeyPair()); System.out.println(keyPair.getPrivate().getEncoded().length); }

  • c# class design - what can I use instead of "static abstract"?

    - by Ryan
    I want to do the following public abstract class MyAbstractClass { public static abstract int MagicId { get; } public static void DoSomeMagic() { // Need to get the MagicId value defined in the concrete implementation } } public class MyConcreteClass : MyAbstractClass { public static override int MagicId { get { return 123; } } } However I can't because you can't have static abstract members. I understand why I can't do this - any recommendations for a design that will achieve much the same result? (For clarity - what I am trying to do is provide a library with an abstract base class but the concrete versions MUST implement a few properties/methods themselves and yes, there are good reasons for keeping it static.)

  • In String.replace("\c","") what ASCII value is ""?

    - by Tom
    Hi, im just writing my own replace method for any weird characters and i used the ASCI value 0, null to replace unwanted characters, i was hoping for them to be 'deleted', but this doesnt work. A gap just appears in the string. What exactly does String.Replace() do when removing a character for ""? Does it shift them all down and then 'delete' the final character or something?

  • License For (Mostly) Open Source Website / Service

    - by Ryan Sullivan
    I have an interesting setup and am not sure how to license a website. I know this is not legal advice, and I am not asking for any. There are so many different Open Source Licenses and I do not have the time to read every last one to see which best fits my situation. Really, I am looking for suggestions and a nudge in the right direction. My setup is: I give away for free version of my web service with a clean website interface. The implementation I use in the actual web site is (almost) identical to what I give away. The main service works the exactly the same way, but the website interface to manage features in the service is fairly different. Really the web interfaces have the same exact backend, and the front ends accomplish the same tasks, but the service I offer on my site is very rich and uses a good deal of javascript, where I kept the interface in the version I give away as simple and javascript-less as possible. Mostly so it is easy to understand and integrate into other sites. I am not entirely sure how I should license this. It is more like I develop an open source service but have a separate site built upon it. I like the GPLv3 but I am not sure if I can use it in this case especially since I am making some money off of google ad's on the site and plan on using amazon affiliates as well. Any help would be greatly appreciated. I do want to open it up as much as possible. But I still want to be able to continue with my own implementation. Thanks in advance for any information or help anyone can provide.
