  • Why is "copy and paste" of code dangerous?

    - by Yigang Wu
    Sometimes, my boss will complain us why we need so long time to implement a feature. Actually, the feature has been implemented in other AP before, you just need to copy and paste codes from there. The cost should be low. It's really a hard question, because copy and paste codes is not a easy thing from my point. Do you have any good reason to explain your boss who doesn't know technology?

  • Executing certain code for every method call in C++

    - by Luís Guilherme
    I have a C++ class I want to inspect. So, I would like to all methods print their parameters and the return, just before getting out. The latter looks somewhat easy. If I do return() for everything, a macro #define return(a) cout << (a) << endl; return (a) would do it (might be wrong) if I padronize all returns to parenthesized (or whatever this may be called). If I want to take this out, just comment out the define. However, printing inputs seems more difficult. Is there a way I can do it, using C++ structures or with a workaroud hack?

  • Question about [Pure] methods

    - by devoured elysium
    Is the following method Pure? I'd say so, as it doesn't change in anyway the current class, thus, everything we can now currenly "see" in the class, before running this method will still be exactly the same after. Am I correct? class Set { ... public ISet<T> UnionWith(ISet<T> set) { ISet<T> unionSet = ... foreach (Element element in this) { unionSet.Add(element); } foreach (Element element in set) { unionSet.Add(element); } return unionSet; } }

  • code style for private methods in c#

    - by illdev
    I just found out, that it seems a common pattern to user UpperFirstLetterPascalCase() for private methods. I for myself, find this completely inconsistent with naming rules of private instance fields and variables and I find it difficult to read/debug, too. I would want to ask, why using a first upper letter for methods could be a better choice than a first lower (doThis())? Just out of curiosity...

  • Are there any modeling tools that can visually generate jpa or sql queries?

    - by Shervin
    Does anyone know of a tool like PowerArchitect or SquirrelSQL or maybe eclipse plugin that lets you also generate jpa/sql queries? Imagine you choosing your database, or your entity beans, and the modeling would reverse engineer your database/entity model, so that you could visually just choose the columns you wanted to select, and it would generate jpa or sql queries for you. For instance choosing A.b and X.y would generate something like this: select a.b, x.y from A a, X x join ......

  • C++/CLI: CA2123: Requires SecurityCriticalAttribute?

    - by TomTom
    I am a little lost on erros like that: Warning 7 CA2123 : Microsoft.Security : Add the following security attribute to 'RithmicConnector::Connect(String^)' in order to match a LinkDemand on base method 'IConnector::Connect(String^)': 'SecurityCriticalAttribute'. c:\work\nettecture\tradex\source\tradex.connectivity.rithmic\rithmicconnector.cpp 52 Tradex.Connectivity.Rithmic Where do I add the SecurityCriticalAttribute? I tried on the header file - but the error does not disappear. I have one of those pretty much on every exposed method of a (managed C++) interface DLL. And I want CA to run through. How do I fix those? Regards

  • PHP code to convert a MySQL query to CSV

    - by Reilly
    What is the most efficient way to convert a MySQL query to CSV in PHP please? It would be best to avoid temp files as this reduces portability (dir paths and setting file-system permissions required). The CSV should also include one top line of field names. Cheers.

  • Code behind methods vs. Jquery AJAX calls

    - by punkouter
    Theres a war brewing I can feel it! Old school coders are used to having every server control create events in the .cs files.. for example.. Getting the Initial load of data, Saving Data, Deleting data... and then binding datasources to the server control.. New school coders want to do it in Jquery + AJAX calls to .svc files... That gives automatic no post backs so that is a advantage... and I think its a different way of thinking.. All of a sudden the UI related events are all being done in Jquery.. What is the most modern and efficient way to go ? How can I convince the old school coders to let us you this new paradigm ? (assuming it is the better way)

  • What is the problem with this code?

    - by Giffyguy
    The compile error I'm getting is "newline in constant" The error occurs where the four asterisks are (****). I can't debug, because the solution won't build successfully. <script type="text/javascript"> function TNClicked(fullImgURL, TNID) { document.getElementById("<%= this.imgFull.ClientID %>").src = fullImgURL; var pnlFullImage = document.getElementById("<%= this.pnlFullImage.ClientID %>"); if (pnlFullImage.style.visibility != "visible") pnlFullImage.style.visibility = "visible"; document.getElementById("<%= this.tcImage.ClientID %>").innerHTML = TNID; //document.forms[0].ctl00$ctl00$ctl00$cntBody$hfImage.value = TNID; //****document.getElementById("<%= this.hfImage").setAttribute("value", TNID); //document.getElementById("<%= this.hfImage.ClientID %>").value = TNID; } </script>

  • c# - SQL - speed up code to DB

    - by user228058
    I have a page with 26 sections - one for each letter of the alphabet. I'm retrieving a list of manufacturers from the database, and for each one, creating a link - using a different field in the Database. So currently, I leave the connection open, then do a new SELECT by each letter, WHERE the Name LIKE that letter. It's very slow, though. What's a better way to do this? TIA

  • asp.net: Where can I put my source files.

    - by David Sykes
    I am developing a web form using Visual Web Developer Currently I have class source files in the same directory as the web form, or in the App_Code folder. I'd like to organise the files into folders within the web form folder, but I can't find a way of adding a reference to the folders, and they don't seem to be being picked up automatically. These are files that are under constant development. What is the asp.net/c#'s equivalent concept to c++'s #include?

  • Operating System for first production windows server code?

    - by Unkwntech
    I'm getting ready to purchase a server for me to deploy my first windows based (C# .NET) application but I'm not familiar with using windows for hosted applications. I have the choice of the following versions of windows: Windows Server 2003 Windows Server 2003 Web Windows Server 2003 Enterprise Windows Server 2008 Windows Server 2008 Web Windows Server 2008 Enterprise Would one of these be better for deploying a C# .NET application? EDIT: There will be 3 applications deployed but each will basically be the same, they will be services that are driven from data being brought in from a website that will likely run on the same server. http://www.microsoft.com/windowsserver2008/en/us/compare-roles.aspx

  • WordPress: don't show 404 when no posts exist

    - by philfreo
    Currently there is a bug in WordPress if you have a Posts Page set under: Settings-Reading-A Static Page-Posts Page If there are posts, than the page (e.g. with a slug called news) displays the post, and uses index.php from the theme. But, with this configuration, if there are no posts, then it calls the theme's 404 page. This is definitely a bug, and has been submitted (Ticket #10822). It should be letting index.php show whatever it wants upon !have_posts(), but right now the page doesn't seem to be called at all. My question is: is there a workaround for this bug without modifying core wp files? I'd be open to a plugin, theme changes, a custom page template, htaccess changes, etc.
