  • What is the difference between a private and public funtion?

    - by Kyle
    I am a new programmer, and I started in C and am now starting to enjoy JavaScript and a tiny bit of PHP more. Lately I've heard the terms 'private' and 'public' functions a lot. Could anybody give an explanation of the both and how they are of use to a programmer? And I'm probably totally wrong here... but is a (function(){}) in javascript a private function?

  • How prevent anyone from stealing my shared_ptr?

    - by Kyle
    So, I use boost::shared_ptr for all the various reference-counting benefits it provides -- reference counting for starters, obviously, but also the ability to copy, assign, and therefore store in STL Containers. The problem is, if I pass it to just one "malicious" function or object, the object can save the ptr and then I'll never be able to de-allocate it without the foreign function or object nicely relinquishing its ownership. Ultimately, I try to keep object ownership explicit. I accomplish this by having the owner keep the only shared_ptr to the object, and "guest" objects only store weak_ptrs to the object. I really don't want the "shared" part of shared_ptr, but I'm required to use shared_ptr in order to make weak_ptrs. I want to use scoped_ptr, but it's extremely limited since you can't copy it. You can't store it in a container, you can't lend out weak_ptrs from it, and you can't transfer ownership to a new manager. What's the solution?

  • How can I force this z-index?

    - by Kyle Sevenoaks
    On euroworker.no/order (add something to the cart with Kjøp and Handlevogn). I have a tooltip that shows the picture of the product when you hover the product name, for some reason it shows above the name, but under other elements, like lines and other product names. JSFiddle of the tooltip code here. And also how can I get the tooltip to appear in the middle? I tried right:50%; but guess that's not right. Thanks.

  • The Impossible Layout?

    - by Kyle K
    I'm beginning to think this is impossible, but thought I'd ask you guys. Basically it's a 2 column layout, but the "business" wants the following: -Always take up the entire browser window -Accommodate resizing of browser window -Left column will be fixed width, but that width should be flexible from page-to-page. -Left column has a region at the top with fixed height. -Left column has a bottom region. It should take up the remaining vertical space of browser window. If content is very large, it will have a scroll bar just for that region. -Right column should take up remaining horizontal space of browser window. -Right column has a region at the top with fixed height. -Right column has a bottom region. It should take up the remaining vertical space of browser window. If content is very large, it will have a scroll bar just for that region. I've tried everything...divs, floated, absolutely positioned, tables, divs in tables... Is this even possible? Here's an image of what it should look like: http://imgur.com/zk1jP.png

  • FastCGI, PHP, Sendmail, and Codeigniter

    - by Kyle J. Dye
    Hi Everyone. I am experiencing an odd issue. I just switched to FastCGI (Apache) because of the big performance boost. Everything is working great, except when I attempt to use sendmail (Codeigniter Class or just raw PHP). I have tested with and without CI and still get a 500 internal server error when trying to send. Could this be getting caused by a discrepency in how FastCGI utilizes sendmail? Has anyone else experienced this issue? Also, the email will send, it just errors afterwards. Please let me know a solution if you have one! Thanks! :)

  • Sending out 20,000+ emails with asp.net

    - by Kyle
    I am writing an application that will need to send a massive amount of emails to our students who will be selected from our database (each email will be personalized to the extent that will include their name, course of study etc...so needs to be sent one at a time). I could do this looping over an SmtpClient, but I'm afraid that with the numbers I'm trying to send, I'll ultimately run into timeout issues or my thread being killed because of lack of machine resources. At this point I'm just looking for suggestions of a better way to handle this, or if looping over SmtpClient is an ok solution, how I should go about handling it to prevent what I posted above. Would a web service be a better alternative? Please advise, TIA

  • Getting 0x80131902 when calling COM+ component

    - by Kyle W
    I created a COM+ component in .Net. It needs to use a configuration file, so I've created a directory with an application.manifest and application.config file and set that as the Application Root Directory. Now when I try to create an instance of that object, I get the following HRESULT: 0x80131902. I can't seem to find exactly what this means, except that there is a problem loading the app-domain. If I don't set the Application Root Directory, it loads just fine (but doesn't have access to the config).

  • script validation error

    - by Kyle Sevenoaks
    Hi, there is a script in my html tag <script type="text/javascript"> function setTaxDisplay(display) { window.location.href += (window.location.href.indexOf('?') > -1 ? '&' : '?') + 'taxInclude=' + display; } </script> When passed to validation It returns that the ampersand there isn't valid, but it's absolutely vital to the function of the page, is there a way I can make the validator ignore this? I don't need to validate the page, I'm no JS expert at all I'm not sure if I can replace it with &amp;. Thanks.

  • C# COM+ component isn't getting the constructor string

    - by Kyle W
    I've created a COM+ component in C# with a strong name, COM Visible, ProgId, etc... I've then registered the assembly with regasm, and imported it into the COM+ Applications in Component Services. It runs just fine, and loads up the DLL, except that the constructor string that is passed in is always empty. The method signature is protected override void Construct(string constructString), and it is being called before the method on the actual component. In the component details in COM+ Applications, the constructor string is checked and a value is entered. Any help is appreciated.

  • WPF Moving Element problem

    - by Kyle
    Hello, I am probably over-doing a very simple problem, but this is what I have a the moment: I have several buttons and a listbox of items in which the user can select and interact with. My application also moves those elements in accordance to the application width/height, such as follows: listBox1.Margin = new Thickness(this.ActualWidth * 0.84, this.ActualHeight * 0.3, 0, 0); I am able to select the items within the listbox and click on buttons appropriately while in windowed mode, but as I begin to stretch the application larger, I try to click on the items, and I cannot do so.. is this because I also need to update their hit-detection rectangles as well? Or perhaps am I moving the items incorrectly? I am at a loss.. any information would be very helpful at this point...thanks!

  • passing LIMIT as parameters to MySQL sproc

    - by Kyle
    I'm creating a paging class and need to pass in two parameters to my MySQL stored procedure for the LIMIT clause. I'm passing them in as INTs and trying something like this SELECT * FROM `MyTable` LIMIT MyFirstParamInt, MySecondParamInt it gives me an error when I try and save the sproc though. Is there a way to do this that I'm just missing? Or am I going to have to EVAL the whole query and EXECUTE it?

  • How can I build a voting system to support multiple types of objects to vote on?

    - by Kyle Hayes
    I'm really looking for something very similar to the way SO is setup where a few different kinds of things can be voted on (questions AND answers). What kind of DB schema, generally, could I use to support voting on many different kinds of objects? Would I have a single Vote table that would have references to other objects in the database? Or do I have to have or should have a separate vote table for each of the objects I would like to vote on.

  • iPhone keeps going into dim/sleep mode even with the proper API calls.

    - by Kyle
    I call: [[ UIApplication sharedApplication ] setIdleTimerDisabled: YES ] on the applicationDidFinishLaunching event.. I set a breakpoint on it, which fires so I know it's getting called.. I've also called this function in other places as well.. Basically, a 3G iPhone will still go into sleep mode, but my 3GS won't. Has anyone seen this behavior before? Both are running the latest OS versions. Thanks for reading!

  • Android: Having trouble getting html from webpage

    - by Kyle
    Hi, I'm writing an android application that is supposed to get the html from a php page and use the parsed data from thepage. I've searched for this issue on here, and ended up using some code from an example another poster put up. Here is my code so far: HttpClient client = new DefaultHttpClient(); HttpGet request = new HttpGet(url); try { Log.d("first","first"); HttpResponse response = client.execute(request); String html = ""; Log.d("second","second"); InputStream in = response.getEntity().getContent(); Log.d("third","third"); BufferedReader reader = new BufferedReader(new InputStreamReader(in)); Log.d("fourth","fourth"); StringBuilder str = new StringBuilder(); String line = null; Log.d("fifth","fifth"); while((line = reader.readLine()) != null) { Log.d("request line",line); } in.close(); } catch (ClientProtocolException e) { } catch (IOException e) { // TODO Auto-generated catch block Log.d("error", "error"); } Log.d("end","end"); } Like I said before, the url is a php page. Whenever I run this code, it prints out the first first message, but then prints out the error error message and then finally the end end message. I've tried modifying the headers, but I've had no luck with it. Any help would be greatly appreciated as I don't know what I'm doing wrong. Thanks!

  • Faster Insertion of Records into a Table with SQLAlchemy

    - by Kyle Brandt
    I am parsing a log and inserting it into either MySQL or SQLite using SQLAlchemy and Python. Right now I open a connection to the DB, and as I loop over each line, I insert it after it is parsed (This is just one big table right now, not very experienced with SQL). I then close the connection when the loop is done. The summarized code is: log_table = schema.Table('log_table', metadata, schema.Column('id', types.Integer, primary_key=True), schema.Column('time', types.DateTime), schema.Column('ip', types.String(length=15)) .... engine = create_engine(...) metadata.bind = engine connection = engine.connect() .... for line in file_to_parse: m = line_regex.match(line) if m: fields = m.groupdict() pythonified = pythoninfy_log(fields) #Turn them into ints, datatimes, etc if use_sql: ins = log_table.insert(values=pythonified) connection.execute(ins) parsed += 1 My two questions are: Is there a way to speed up the inserts within this basic framework? Maybe have a Queue of inserts and some insertion threads, some sort of bulk inserts, etc? When I used MySQL, for about ~1.2 million records the insert time was 15 minutes. With SQLite, the insert time was a little over an hour. Does that time difference between the db engines seem about right, or does it mean I am doing something very wrong?

  • "Ghost" values in PHP/Smarty.

    - by Kyle Sevenoaks
    I've been working on a site for a while changing the layout and skin of a webshop checkout process. I've noticed that if you go all the way through the process until the last page, then click the link to go back to the view products page, the delivery method price displays underneath the navigation buttons, until you refresh and it goes away again. I've downloaded both sourced from the browser (Chrome, but this bug applies to all browsers) and used a file difference tool to display the differences, the result being only: < error.html vs > normal.html 34c34 < <link href="gzip.php?file=167842c1496093fbcd391b41cf7b03da.css&time=1272272181" rel="Stylesheet" type="text/css"/> --- > <link href="gzip.php?file=167842c1496093fbcd391b41cf7b03da.css&time=1272272348" rel="Stylesheet" type="text/css"/> Which is just the way it zips up the CSS stylesheets. (afaik) Has anyone ever encountered such a problem, or anything similar? Normal: Error: I can't even hazard a guess as to what is causing this, at all. I've searched over Google for anything and come up with nothing. What could be causing this? The site in question is Euroworker.no. HTML @ Pastebin. Smarty snippet: {if !$CANONICAL} {canonical}{self}{/canonical} {/if} <link rel="canonical" href="{$CANONICAL}" /> <!-- Css includes --> {includeCss file="frontend/Frontend.css"} {includeCss file="backend/stat.css"} {if {isRTL}} {includeCss file="frontend/FrontendRTL.css"} {/if} {compiledCss glue=true nameMethod=hash} <!--[if lt IE 8]> <link href="stylesheet/frontend/FrontendIE.css" rel="Stylesheet" type="text/css"/> {if $ieCss} <link href="{$ieCss}" rel="Stylesheet" type="text/css"/> {/if} <![endif]--> Thanks.

  • How to efficiently implement a blocking call with Rails, while letting the client wait for the reply

    - by Kyle Heironimus
    We have a web service written in Rails. The API is published and we cannot change it. Our app communicates with a remote web service that sometimes hangs or takes several seconds to reply. Client -> Our Web Service -> Remote Web Service Currently, if the remote web service hangs for 5 seconds, one of our rails processes on our web service also hangs with it, which is what we need to avoid. I've seen things such as mod-x-sendfile, modporter, and delayed jobs, but the best I can tell, they all assume the client is not waiting for an answer. Since the API is already established, we cannot tell the client "I'm attempting to do what you want, check back later for the answer." The best option we have come up with so far is to add a second, non-rails web server running eventmachine to process these particular calls. Is there a better way?
