  • What do you call the concept of dynamic data definition?

    - by DJTripleThreat
    Maybe this is simpler and more straightforward then what I'm thinking but I can't seem to find this concept on google anywhere. The concept is this: You have a table in a database and the table has a specified number of columns. However, it has been asked of me by previous clients that there also be a set of dynamic user defined columns that can be added on the fly. What is this concept called and is it considered a design pattern?

  • Object Events, how do are they implemented

    - by Malfist
    Events are really awesome, and I wouldn't know what I would do without them, but they're a mystery to me. I'm talking about events in a sense, a function(s) is called if a property, or value, a special event happens. I have only the vaguest idea how these actually work. I know it's an observer pattern, but I don't truly know how it works and/or how to implement it. Can someone explain that to me?

  • How would one go about adding (minor) syntactic sugars to Java?

    - by polygenelubricants
    Suppose I want to add minor syntactic sugars to Java. Just little things like adding regex pattern literals, or perhaps base-2 literals, or multiline strings, etc. Nothing major grammatically (at least for now). How would one go about doing this? Do I need to extend the bytecode compiler? (Is that possible?) Can I write Eclipse plugins to do simple source code transforms before feeding it to the standard Java compiler?

  • Get scanner to include but ignore quoted text?

    - by user1086516
    Basically my problem is this, I need to parse text where , is the delimiter but anything in " " quotes should not be checked for a delimiter. Is this what the Scanner.skip method is for? I would check it myself but I don't understand how to write a regex pattern in java where the token is something in between two " ". I also want to include any quoted text in the proper token which was delimited by the valid ,.

  • Strange phantom header margin bug html/css

    - by MickyJimbo
    So I'm creating this website and there is a strange untraceable bug that causes the header to move down 10 or so pixels. On a refresh the header could be correct or it could be broken. I've been testing it on Adobe Browserlab and the results are different every time.There is no discernible pattern making it incredible hard to track down. http://www.freeimagehosting.net/uploads/c866bf594d.jpg Has anyone ever had this problem and been able to fix it?

  • Refactoring nested foreach statement

    - by dotnetdev
    Hi, I have a method with a nested foreach collection (iterate a set of objects and then look inside each object). I saw in a book a good pattern to make this much more elegant but cannot remember/find the code example. How else could I make this more tidy? The code is just a typical nested foreach statement so I have not provided a code sample. Thanks

  • NHibernate (or other worth recommendation ORM), real life example?

    - by migajek
    I'd like to learn database applications in C# and I'm about to select some framework. I heard many recommendations of NHibernate, however I haven't decided yet. Anyway, I'd like to know if there's any real-life example (with sources) of NHibernate in C#, to learn best practices etc.? I know all of them are probably covered in the docs, but working example helps a lot understanding the proper development pattern.

  • Swiz Framework and Spring Framework - Are they related?

    - by theband
    I was looking into Swiz framework and i felt the same of Spring. Just i felt the difference between these two is one is JAVA based and the other is Action Script based. http://swizframework.org/ http://www.springsource.org/ My Question is: Does the goal of the both framework is same? Does the pattern they apply is same or different? The concept of beans, dependency injection and IOC lies in both.

  • Are There Any Other Web Programming Languages That Can Be Used Without A Framework Aside From PHP?

    - by Ygam
    Python needs a framework, so does Java (for the web). I don't know much about Ruby or Coldfusion. But is there another language out there for the web that can stand alone as it is without a need for a framework or without strict adherence to a design pattern (MVC and the likes) aside from PHP? BTW, the statement that Python and Java needs a framework to work with the web came purely from my readings on articles and books; I might be mistaken.

  • A version of the Windows "FILE:" port which does not prompt for the file name but autogenerates one.

    - by Thorbjørn Ravn Andersen
    Hi. I have a process where one of the things to do is to capture the output from a print into a file for further processing. For this I have configured a "FILE:" printer port which works very nicely but asks everytime for the file name to use. Unfortunately "FILE" is not a very descriptive word when trying to use a search engine :( Is there a small driver somewhere which does exactly the same as the FILE: driver, but can automatically generate a filename (perhaps based on a pattern) and just print to that?

  • Console output spits out Chinese(?) characters

    - by a_person
    This is a real shot in the dark, however maybe someone had a similar issue. Some console apps are being invoked by either SQL Server 2008, or Autosys (job schedule) under Windows Server 2008; output results of execution are being saved into .txt files. Every so often, with no definite pattern as far as I can tell saved output is displayed as a series of what I presume are Chinese characters. Have anyone encountered phenomenon above?

  • Extract dates from filename(C#3.0)

    - by Newbie
    I have a situation where I need to extract dates from the file names whose general pattern is [filename_]YYYYMMDD[.fileExtension] e.g. "xxx_20100326.xls" or x2v_20100326.csv The below program does the work //Number of charecter in the substring is set to 8 //since the length of YYYYMMDD is 8 public static string ExtractDatesFromFileNames(string fileName) { return fileName.Substring(fileName.IndexOf("_") + 1, 8); } Is there any better option of achieving the same? I am basically looking for standard practice. I am using C#3.0 and dotnet framework 3.5 Thanks
