  • Up to date, JPA compliant GenericDAO Implementation

    - by HDave
    I read this article: http://www.ibm.com/developerworks/java/library/j-genericdao.html several times and believe I understand what it is saying. However, it is 4 years old and I have a JPA compliant Java application to contend with. In addition, I see that there is a JPATemplate in Spring that has some good functionality, but the Spring documentation says it is already deprecated! Can anybody point me to a solid, modern, JPA compliant, Spring based, working example of a GenericDAOImpl that proxies an Interface to provide generic finder execution?

  • LINQ to SQL does not update when data has changed in database

    - by aximili
    I have this problem where after a field (say Field3 in table MyTable) is updated on the database, MyTable.Field3 (in C#) is still returning the old value. I suspect there is some caching...? How do I force it to: Read the value from the database? OR Update the value in the MyTable class? Or is there anything I miss? Thank you in advance.

  • SIMPLE file reading in Perl

    - by Befall
    Hey guys, The other answered questions were a bit complicated for me, as I'm extremely new to using Perl. I'm curious how Perl reads in the files, how to tell it to advance to the next line in the text file, and how to make it read all lines in the .txt file until, for example, it reaches item "banana". Any and all help would be appreciated, thanks!

  • What are the BEST resources for learning WPF & .NET?

    - by dicroce
    I'm a longtime C/C++ Unix guy. I recently started work in a new position that's gonna eventually require C# and WPF (and probably some LINQ). What are the best resources to quickly come up to speed on all these Microsoft technologies? Years ago I read Petzold's book and loved it because it was so complete and by the end I really felt like I knew what I was doing... Is their something equivalent for the .NET world?

  • Learning to create beautiful /next-generation GUI

    - by ShaChris23
    I really want to create a stunning-looking GUI desktop application that looks like, for example: Mac OS X interface Picasa desktop client on windows IPhone apps Office 2007 I've mostly been programming GUI using Qt/Swing/WinForm and I'm tired of creating so plain looking GUI, lol. So I was thinking about diving into stuff like: jQuery WPF/C# iPhone SDK Silverlight Adobe Air/Flex Just to get some ideas on how to create really cool looking UI. Does that sound like a good list? Any developers here that could share what platform they use to create very cool looking desktop app? On a sidenote, I really wonder what developers at Apple / Microsoft use to develop their own cool-looking software. EDIT A lot of responses talk about the importance of usability over "cool-looking".. I totally agree that usability and simplicity are the most important aspects of user interface design. I've been doing GUI development for a while now ( 3 years), so that I understand. But using cool-looking UI also improves user experience + it could make big difference on whether or not your software sells. I mean, otherwise why would Microsoft/Apple try to make their OS UI look "cooler" everytime there's a new version? Why would websites like pragprog.com, or versionsapp.com. make their websites look like that? Basically you kill 2 birds with one stone: stunnning-looking UI + super usability (because it looks simple and intuitive). That is what I'm striving for. And as far as I know, I cannot achieve that using Qt/Winform. Most of the books I have read just show you how to make average-looking (read: 1990's) UI. I want to learn how to create cool-looking UI. And the only place I see cool-looking UIs these days are the technology I list above. I'm not enamored with any technology; but I just want to know how things are done in other technology to see if I could apply them to the technology I'm using, or see if I could use those technology in my line of work. An example: if I were to pick between this UI and this UI, I probably would pick the latter, if just based on looks alone. Functionally, they are just the same UI; they both allow you to keep track of your time. They both contain buttons and textboxes, etc. But the fact that they look different, also differentiate them in terms of attractiveness. So in all, I think the "ice on the cake" is very important. I would say it's the thing you strive for after you are certain you have a totally intuitive, usable UI.

  • Upgrading mysql from 4.1.22 to 5.0

    - by Arsenal
    Hi, I'm trying to upgrade our company's 4.1.22 version of MySQL to 5. I'm using sudo yum --enablerepo=centosplus upgrade mysql* but keep getting an error of conflicted files with the 4.1 version. Does that mean there really isn't any other way than uninstalling 4.1 and installing 5.0? I have read that using the yum upgrade command should work however... Thanks in advance!

  • Pull info from Excel Spreadsheet into C# Web Application

    - by Gene
    I want to show information from an excel spreadsheet in a web page. The xls will have maybe 5 columns, and as many rows as needed. The columns will be 'Name', 'Created Date', 'Expired Date', 'Owner', and maybe down the road maybe more. What I would like is for the C# to nightly read the xls, and display the information in a table on the website. If there is a PDF available for download I am going to link that as well. Thanks in advance, Gene

  • C# immutable object usage best practices? Should I be using them as much as possible?

    - by Daniel
    Say I have a simple object such as class Something { public int SomeInt { get; set; } } I have read that using immutable objects are faster and a better means of using business objects? If this is so, should i strive to make all my objects as such: class ImmutableSomething { public int SomeInt { get { return m_someInt; } } private int m_someInt = 0; public void ChangeSomeInt(int newValue) { m_someInt = newvalue; } } What do you reckon?

  • Python double underscore mangling

    - by gnr
    I am a bit confused by this behavior (using python 3.2): class Bar: pass class Foo: def __init__(self): self.__cache = None bar = Bar() bar.__cache = None foo = Foo() print(vars(bar)) #returns {'__cache': None} print(vars(foo)) #returns {'_Foo__cache': None} I've read up a bit on how double-underscores cause attribute names to be "mangled", but I would have expected the same name-mangling in both cases above. The meaning of a single- and a double-underscore before an object name in Python Any ideas what's going on here?

  • Excel 2007 and Unicode

    - by pjlasl
    I have an israeli spreadsheet reading right to left. When I read the values (using VBA) it places a question mark (?) at the beginning and end of the text, in other words it wraps the text with the question mark (ie ?0123456?). If you type Range("A2").value or .value2 or .text the results are the same. Any idea on how to prevent this?

  • Pythonic reading from config files

    - by Adam Matan
    Hi, I have a python class which reads a config file using ConfigParser: Config file: [geography] Xmin=6.6 Xmax=18.6 Ymin=36.6 YMax=47.1 Python code: class Slicer: def __init__(self, config_file_name): config = ConfigParser.ConfigParser() config.read(config_file_name) # Rad the lines from the file self.x_min = config.getfloat('geography', 'xmin') self.x_max = config.getfloat('geography', 'xmax') self.y_min = config.getfloat('geography', 'ymin') self.y_max = config.getfloat('geography', 'ymax') I feel that the last four lines are repetitive, and should somehow be compressed to one Pythonic line that would create a self.item variable for each item in the section. Any ideas? Adam
