• How easy would it be to refactor a small JSP/Servlet/JDBC project to SpringMVC/Hibernate

  - by John

  With reference to this post, I am considering starting a new web-based Java project. Since I don't know Spring/Hibernate I was concerned if it's a bad plan to start learning them while creating a new project, especially since it will slow down the early development. One idea I had was to write a prototype using tech I do know, namely JSP/Servlets/JDBC, since I can get this running much quicker with my current knowledge. I could then throw the whole thing away and start over with Spring, etc, but I'd like to consider how easy it would be to refactor a smallish project from JSP/Servlets/JDB to SpringMVC/Hibernate? My DB could of course be re-used but what about other code... would I expect to save most of it plugged into an MVC framework, or is the paradigm shift big enough this would cause more trouble than it avoids? Please use the other question for more general advice on choosing technologies

• Creating a Programming Language

  - by Lucifer

  Don't worry, I'm not going to ask that question, yet again... I am wanting to create my own programming language, just for learning sake. I don't want anything other than possibly a few links to head me into the right direction. MSDN Documentation on C# that is specific to what is required to create a language would be great! For the time being, all I am wanting to create is a very simple language that allows me to Create a Form, add a control to it, give that control a location, and maybe even some properties like a Text property, or maybe even a Color property. That's it! Any help / advice at all is greatly appreciated! Thank you :)

• Unread email notifier, most practical approach

  - by Michael Pasqualone

  I'm in the process of writing a small php-cli script that will loop over over my personal inbox and then send me an SMS via a gateway. The question I have is: As will have the script launch via cron every 10 minutes, if there is an email sitting in my inbox that is not read before the next script launch then I will receive 2 sms. Does any one (pseudocode will do) have any idea what the best practice would be in php5 to ensure only 1 SMS is sent? What I am currently learning towards is towards storing the message ID in a sqlite DB and flagging a field whether an SMS has been sent or not - but wondering if there is an easier way?

• Simplest way to extend doctrine for MVC Models

  - by RobertPitt

  Im developing my own framework that uses namespaces. Doctrine is already integrated into my auto loading system and im now at the stage where ill be creating the model system for my application Usually i would create a simple model like so: namespace Application\Models; class Users extends \Framework\Models\Database{} which would inherit all the default database model methods, But with Doctrine im still learning how it all works, as its not just a simple DBAL. I need to understand whats the part of doctrine my classes would extend where i can do the following: namespace Application\Models; class Users Extends Doctrine\Something\Table { public $__table_name = "users"; } And thus within the controller i would be able to do the following: public function Display($uid) { $User = $this->Model->Users->findOne(array("id" => (int)$id)); } Anyone help me get my head around this ?

• Best ways to reuse Java methods

  - by carillonator

  I'm learning Java and OOP, and have been doing the problems at Project Euler for practice (awesome site btw). I find myself doing many of the same things over and over, like: checking if an integer is prime/generating primes generating the Fibonacci series checking if a number is a palindrome What is the best way to store and call these methods? Should I write a utility class and then import it? If so, do I import a .class file or the .java source? I'm working from a plain text editor and the Mac terminal. Thanks!

• Compact web server with Lua support?

  - by OverTheRainbow

  Hello, I need to find a very compact, cross-platform web server that can run Lua scripts, ie. either a regular web server like Mongoose that will forward queries to a Lua program in eg. FastCGI, or a web server itself written in Lua which will save the need to provide a separate web server. I recently started learning about Lua so am still in the dark about what is available out there, save for the three I came accross: Barracuda Embedded Web Server http://barracudaserver.com/ba/doc/ Xavante - Lua HTTP 1.1 Web server http://keplerproject.github.com/xavante/ Haserl http://haserl.sourceforge.net/ If someone's already done this recently, what solution would you recommend along with any tutorial/article that would get me started? Thank you.

• Do you draw the entire object?

  - by vbman11

  Hi I'm working on learning 3d game development and I'm starting with JavaScript and the html5 canvas and I was wondering if I were to have a 3d model do I draw the entire model(front, back, etc) and let the web browser decide what to render or should I try to just draw the sides that are in view of the camera? I ask this because I can see how it would be faster to do the latter of the 2 but that can get very complex and I'll need to do quite a bit more research to find how to do that. Thanks!!

• Does Python Django support custom SQL and denormalized databases with no Foreign Key relationships?

  - by Jay

  I've just started learning Python Django and have a lot of experience building high traffic websites using PHP and MySQL. What worries me so far is Python's overly optimistic approach that you will never need to write custom SQL and that it automatically creates all these Foreign Key relationships in your database. The one thing I've learned in the last few years of building Chess.com is that its impossible to NOT write custom SQL when you're dealing with something like MySQL that frequently needs to be told what indexes it should use (or avoid), and that Foreign Keys are a death sentence. Percona's strongest recommendation was for us to remove all FKs for optimal performance. Is there a way in Django to do this in the models file? create relationships without creating actual DB FKs? Or is there a way to start at the database level, design/create my database, and then have Django reverse engineer the models file?

• How do I use the Microsoft VSTO interfaces?

  - by user557554

  hi, I would like to create an addin for microsoft outlook, and am using the visual studio tools to do so. However I am really struggling to get my head around the use of interfaces within the VSTO environment - the resources on MSDN show many useful looking interfaces, but I am unsure how to use these interfaces to access data. For example I am trying to add a new folder into an IMAP account but am finding it very difficult to work out how to get outlook to do so. Can anyone recommend any good resources for learning how to use VSTO (I have VSTO for dummies, but it doesn't cover the level of detail I need, I have been using MSDN, but I have found it doesnt offer much information on how to use the interfaces etc.) thanks.

• DependencyProperty Orientation problem

  - by byte

  I am learning WPF and am trying to create my first UserControl. My UserControl consists of StackPanel StackPanel contains a Label and TextBox I am trying to create two Dependency Properties Text for the Label Orientation for the StackPanel - The orientation will affect the position of the Label and TextBox effectively I have successfully created a Text dependency property and bind it to my UserControls . But when I created the Orientation property, I seem to get following error in get property The as operator must be used with a reference type or nullable type ('System.Windows.Controls.Orientation' is a non-nullable value type) public static DependencyProperty OrientationProperty = DependencyProperty.Register("Orientation", typeof(System.Windows.Controls.Orientation), typeof(MyControl), new PropertyMetadata((System.Windows.Controls.Orientation)(Orientation.Horizontal))); public Orientation Orientation { get { return GetValue(OrientationProperty) as System.Windows.Controls.Orientation; } set { SetValue(OrientationProperty, value); } } Appreciate your help.

• How to make some simple GUI controls?

  - by daniels

  I need to make a DirectX or OpenGL app and i will need a custom GUI for that. I think a button, a input text box, a list box (that will need a scroll bar as there will be more items that can fit on the screen) and a slider control will be enough. I know about CeGUI framework but i just don't like it, way too many XML files for my taste. My question is where should i start in learning how to do this custom GUI controls, are there any tutorial available or any material that could get me started? I haven't done a GUI contol myself before.

• Is there such a thing as a C# style extension method in C++ ?

  - by Gary Willoughby

  I'm currently learning C++ and i run into the simple problem of converting an int to a string. I've worked around it using: string IntToString(int Number) { stringstream Stream; Stream << Number; return Stream.str(); } but though it would be more elegant to use something like: int x = 5; string y = x.toString(); but how do i add the toString() method to a built in type? or am i missing something totally fundamental?

• In MS Access is there a way to allow forms to update while maintaning Read Only

  - by Alex

  I have several forms linked tables via queries. The form pull data such as sales and ratios by selecting a product from the main's form's combo box. I am however having to issues: 1- I would ultimately prefer the combo box to be a free entry; however by just entering in the box and hitting enter (not a button called “enter on a screen” which would initiate recalcs, just normal enter), while it does bring the new information in sub-forms it also changes the information in the original table. If I make the table read only that it just doesn't allow the form to work by saying that the table is read only. 2- The same Read only issue occurs when another user with read only rights tries to use the database. I understand that ready only is functioning as intended, however I am wondering if there is way to make some functions work while disallowing the updating. I am unfortunately learning on the go, so go easy plz. Thank you

• What lessons have you learned about using a wiki as a development tool?

  - by Vivek Kodira

  I'd asked a question a while back about ways to encourage my team to collaborate. The tool we use is a wiki. Since this is the first time we are using the wiki (formally and as a team), we are learning by committing mistakes. One of the lessons has been that a wiki isn't suitable for tracking activities. It is better to use a tool built for-the-job (will elaborate if necessary). Are there other such anti-patterns? What development tasks would you NOT recommend using a wiki for (even though it may seem suitable at first glance)? Edit: Making this a community-wiki since it is probably unlikely that there will be 'one' right answer.

• How to write syntax highlighting? c++

  - by ML

  Hi All, I am embarking on some learning and I want to write my own syntax highlighting for files in C++. Can anyone give me ideas on how to go about doing this? To me it seems that when a file is opened: 1. it would need to be parsed and decided what type of source file it is. Trusting the extension might not be full-proof a way to know what keywords/commands apply to what language a way to decide what color each keyword/command gets I want to do this on OS X, C++ or Objective-C Can anyone provide pointers on how I might get started with this?

• Would the world be a better place if there were only one programming language?

  - by Simon

  Well, perhaps not the world, but would it encourage more-re-use, less replication of basic code, or at least an uplift in what is considered basic code, more time advancing the application science and a greater encouragement to share, a more advanced base of understanding for new programmers, since the language could be taught ubiquitously and patterns of teaching would have emerged which were optimised for students learning etc etc? I think all of those things would make the programming world better and would probably have significant commercial benefit too. This is definitely not a religious debate about which language is best, and is predicated on the notion of some super-being having designed the perfect language to start with, which was improbable, but it strikes me that if, from the beginning, there were only a single programming language we may be further along in terms of the evolution of the software industry and software science. And although it is now impossible, if you buy some or all of these assertions is there an argument for standardising on a single language for the future so we can accelerate our collective progress rather than all of us re-inventing some part of the same wheel and consigning our children to the same fate?

• What is the best way to organize Java code since you can't pass by reference?

  - by Adam

  I'm learning how to code in Java after after coming from C. In C I always separated everything into individual functions to make the code easier to follow and edit. I was trying to do this in java but now since I realized that you can't use pointers, I am a bit confused as to what the best way to do this is. So for example I want to have a method that creates four alerts for me. So I pass it an alert builder that can then create the alerts. I can return them in an array, but in my code I already have the alerts individually named, and I would like to keep it that way so I wouldn't need to refer to them as alert[1], alert[2]... etc. So that means I would have to rename them, which would add additional code which would probably be longer than the code in the actual method! Am I thinking about this the right way? Is there anything I can do?

• Using scanf() in C++ programs is faster than using cin ?

  - by zeroDivisible

  Hello, I don't know if this is true, but when I was reading FAQ on one of the problem providing sites, I found something, that poke my attention: Check your input/output methods. In C++, using cin and cout is too slow. Use these, and you will guarantee not being able to solve any problem with a decent amount of input or output. Use printf and scanf instead. Can someone please clarify this? Is really using scanf() in C++ programs faster than using cin something ? If yes, that is it a good practice to use it in C++ programs? I thought that it was C specific, though I am just learning C++...

• PHP to C# and Vice versa

  - by Daniel Sh.

  I'm in this project: A web page that's gonna be used by the front-end company people to query and update data from a SQL DB. I'm working with visual studio and the code behind (C#) is almost done, so the interactions between SQL and C# and ok. My original idea was to work with ASP.NET which is familiar to me, but that's not gonna be possible. I have to switch to PHP. So, today is my first day learning PHP, checking http://php.net/manual/en/index.php and a lot of things seem quite similar to ASP.NET so I guess it won't be that hard. Anyways, some questions popped up quite fast as I wanted to script something else than a "hello world" . Is there an easy way to get/send C# variables from my class using a php page? I've read soemthing about using XML in order to do so, but still I'm scratching my head, is there another, easier, way to do this?

• Missing something with Reader monad - passing the damn thing around everywhere

  - by Richard Huxton

  Learning Haskell, managing syntax, have a rough grasp of what monads etc are about but I'm clearly missing something. In main I can read my config file, and supply it as runReader (somefunc) myEnv just fine. But somefunc doesn't need access to the myEnv the reader supplies, nor do the next couple in the chain. The function that needs something from myEnv is a tiny leaf function. So - how do I get access to the environment in a function without tagging all the intervening functions as (Reader Env)? That can't be right because otherwise you'd just pass myEnv around in the first place. And passing unused parameters through multiple levels of functions is just ugly (isn't it?). There are plenty of examples I can find on the net but they all seem to have only one level between runReader and accessing the environment.

• Compile C++ from VS08/10 without Run Time Library / MFC

  - by Lienau

  Are there settings I can adjust in Visual Studio so that it does not compile with any run time library or MFC. I started learning C++ to get away from C#'s .Net, and this is just as bad. When I execute the program in a Windows XP virtual machine I get an error. I can compile without the dependencies in Code::Blocks, but I'm more familiar with VS, and prefer many of it's features over those of Code::Blocks. If you know of to get past this, it would be greatly appreciated. Thanks.

• Can't remove first node in linked list

  - by carlmonday

  I'm trying to make a linked list class in python (pointless I know, but it's a learning exercise), and the method I have written to remove a node doesn't work if I try to remove the first element of the linked list. If the node to be removed is anywhere else in the linked list the method works fine. Can someone give me some insight as to where I've gone wrong? Here's my code thus far: class Node: def __init__(self, data=None, next=None): self.data = data self.next = next def __repr__(self): return repr(self.data) def printNodes(self): while self: print self.data self = self.next def removeNode(self, datum): """removes node from linked list""" if self.data == datum: return self.next while self.next: if self.next.data == datum: self.next = self.next.next return self self = self.next

• How can I bind a LinkedList as ItemSource to ListView in WPF XAML?

  I'm learning WPF and would like to have a collection similar to a LinkedList, to where I can add and remove strings. And I want to have a ListView that listen to that collection with databinding. How can I do bind a simple list collection to a ListView in XAML?

• Sliding "pull-down" navigation - what do I use? How do I implement? jQuery?

  - by Josh Carey

  I'm new to Javascript and jQuery, but I'm learning. Here is what I'd like to accomplish: I have a row of navigation "pull-down" tabs that I'd like to animate. Some sliders will have text links to sub-pages and some will not. The bottom portion of the tab should be clickable to go to the main page. Then the sub-page, text links should also be clickable. Here is a graphic example that should make sense of what I'd like to do: http://lionheart.net/downloads/nav-example.png Mouse over, would slide it down. Mouse out, after a second, should auto-slide up. Is this possible with jQuery or something else? Thanks so much for any help you can give me!
