• Beginner, learning as I go - how to get C#/SQLite db set up and ready for testing?

  - by ChrisC

  I've messed with Access a little bit in the past, had one class on OO theory, and one class on console c++ apps. Now, as a hobby project, I'm undertaking to write an actual app, which will be a database app using System.Data.SQLite and C#. I have the db's table structure planned. I have System.Data.SQLite installed and connected to VS Pro. I entered my tables and columns in VS, but that's where I'm stuck. I really don't know how to finish the db set up so I can start creating queries and testing the db structure. Can someone give me guidance to online resources that will help me learn how to get the db properly set up so I can proceed with testing it? I'm hoping for online resources specific to beginners using C# and System.Data.SQLite, but I'll use the closest I can get. Thanks.

• Format SQL Query Result into web menu

  - by highwingers

  I am trying to bhuild a drill down menu for my website, where user will click on a category and it will show the subcategories of that clicked category, there could be n-levels. I am able to write sql query which returns the output exactaly as I want, but the problem is...I dont want to show the whole menu to end user, I would like to open/expand only clicked category. my Query output is: 1 IPTV 2 Jadoo Tv 3 Shava Tv 4 Jalva Tv 5 Programming 6 Microsoft 7 Asp.Net 8 PHP so by default IPTV & Programming Should be displayed, since they are parent, and when I click on IPTV it should open the children of IPTV, like I said there could be n-levels. I was thinking, I can load the output of query to webpage and then control the menu navigation with css/javascript. do you guys have any ideas?

• ASP.Net Vertical Menu with Scroll functionality

  - by Thomas

  Referring to Menu / Scrolling Example I would like to create / find the same functionality for a vertical menu. I tried the following. <asp:Menu ID="menuAccountMembers" runat="server" StaticSubMenuIndent="16px" Visible="true" RenderingMode="Table" ScrollDownImageUrl="~/Resources/scrolldown.jpg" ScrollUpImageUrl="~/Resources/scrollup.jpg"> <Items> But it doesnt display any scrolling images. I am using .net 4.0 Tried setting menuAccountMembers.RenderingCompatibility = new Version(3, 5); as well. If there a property to only display the first 5 root menu items, then show scroll bars for the rest? It can be click-able, no need to hover over to show next item.

• 0/1 Knapsack with irrational weights

  - by user356106

  Consider the 0/1 knapsack problem. The standard Dynamic Programming algorithm applies only when the capacity as well as the weights to fill the knapsack with are integers/ rational numbers. What do you do when the capacity/weights are irrational? The issue is that we can't memoize like we do for integer weights because we may need potentially infinite decimal places for irrational weights - leading to an infinitely large number of columns for the Dynamic Programming Table . Is there any standard method for solving this? Any comments on the complexity of this problem? Any heuristics? What about associated recurrences like (for example): f(x)=1, for x< sqrt(2) f(x)=f(x-sqrt(2))+sqrt(3)

• Running applictions via ruby and multi-core support? (OSX)

  - by Nick Faraday

  Hi All, I'm looking for some tutorials/resources/tips that will show me how to run applications via a ruby script. I have several small tools that we use in our day to day operations that I want to manage their tasks in one ruby script. Basically what I'm trying to do is: run app via ruby script. (wait for result) get result code (success, or error msg) if ok, start the app on its next task. Also each of the tasks are independent so I'd like to take advantage of the 8 cores on my MacPro and run 8 instances at a time. Any resources you could point me towards would be greatly appreciated!

• scanf() (C Language ) confused me

  - by Nano HE

  Hello. When do I need to insert/don't insert & for scanf() in C? Thank you. int main() { char s1[81], s2[81], s3[81]; scanf("%s%s%s", s1, s2, s3); // If replace scanf() with the expression below, it works too. // scanf("%s%s%s", &s1, &s2, &s3); printf("\ns1 = %s\ns2 = %s\ns3 = %s", s1, s2, s3); return 0; } //programming is fun // //s1 = programming //s2 = is //s3 = fun

• Regarding Authlogic and page redirection.

  - by Paddy

  I am using authlogic for authentication in my Rails app. Have named routes for the frequent actions, viz: map.login "login", :controller = "user_sessions", :action = "new" map.logout "logout", :controller = "user_sessions", :action = "destroy" map.register "register", :controller = "users", :action = "new" map.edit 'user/edit/:id', :controller = "users", :action = "edit" But also in my routes.rb i have these automatically created REST routes too: map.resources :user_sessions map.resources :users The problem now is that a user can login from two different routes. Ex: From, http://localhost/login and also from http ://localhost/user_sessions/new. How do i restrict access only from the named route i have defined and not allow from user_sessions/new?

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

  - by Jonas

  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? My idea (not working) is something like this: <Window ...> <Window.Resources> <LinkedList x:Key="myList"></LinkedList> <Window.Resources> <Grid> <ListView Height="100" HorizontalAlignment="Left" Margin="88,134,0,0" Name="listView1" VerticalAlignment="Top" Width="120" ItemsSource="{Binding Source={StaticResource myList}}"/> </Grid> </Window>

• No recent books on MPI: is it dying?

  - by Jono

  I've never used Message Passing Interface (MPI), but I've heard its name thrown about, most recently with Windows HPC Server. I had a quick look on amazon to see if there were any books on it, but they're all dated around 7 or more years ago. Is MPI still a valid technology choice for new applications, or has it been largely superceded by other distributed programming alternatives (e.g. DataSynapse GridServer)? As it's not really an implementation, but rather a standard, what is the likelihood (assuming it's not dead) that learning it will result in better design of distributed programming systems? Is there something else I should be looking at instead?

• How do I send an email from my webpage?

  - by Jordan S

  I am not a web developer but I do have a lot of programming experience in C# and Windows forms programming. On our company webpage my boss wants me to put in a textbox where visitors can submit a comment and press a submit button and that comment will be sent to an email address. Right now, our website uses just plain old html, no php or javascript or anything like that. I am wondering what is the simplest way to accomplish what I need? Can someone point me in the right direction? The website is hosted on an Apache server so I won't be able to use aspx.

• 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.

• Maven archetype from project - how to preserve package names ?

  - by lisak

  Hey, I'm trying to grab my project and generate an Archetype from it via : archetype:create-from-project The thing is, that my project has src/main/java package structure com.sample.app, but the archetype must have it as I want (org.example.game) ... Ideally as user want when generating the project from archetype, but that is impossible I suppose. It would have to grab groupId and artifactId and generate archetype-resources/src/main/java based on this input. Anyway, that's why there is this argument I suppose : packageName mvn archetype:create-from-project -DpackageName=org.example.game But it doesn't work and there is still archetype-resources/src/main/java/org/sample/game ..

• is it possible to include a binary in my project and use it?

  - by Adam S

  I have a binary that's used as a command-line tool to manipulate some files - tool.exe. I would like to include this in my Visual Studio 2008 project and use it from my C# code. I have it in a folder called "Resources" which also has some other files my project uses. I would like to do something like Process myproc = Process.Start("Resources/tool.exe"); but I believe C# has an issue with this because it's looking in the file system rather than the project. How can this be done?

• What notes should I be taking, if any, at the beginning of a project?

  - by Justin R.

  I was recently asked by a Team Leader (not mine) if I would be willing to undertake a programming project. The members of his team are currently pre-occupied with other more important projects. I graduated college two years ago, and up until now programming has only been a hobby of mine. Recently I decided that I would like to pursue a career in software development. I accepted his offer so that I can gain some real-world experience and start building a portfolio. In about an hour I'm scheduled to meet with the Team Leader to discuss the details of what he needs. From a short e-mail exchange with him, I know that the base project is to update an existing ASP.NET form—but I also think there's more to it than that. Considering that I'd like to eventually put this project in a portfolio, what kinds of notes should I take at the meeting?

• How have your coding values changed since graduating?

  - by Matt

  We all walked out of school with the stars in our eyes and little experience in "real-world" programming. How have your opinions on programming as a craft changed since you've gained more experience away from academia? I've become more and more about design a la McConnell : wide use of encapsulation, quality code that gives you warm fuzzy feelings when you read it, maintainability over execution performance, etc..., whereas many of my co-workers have followed a different path of fewer middlemen layers getting in the way, code that is right out in the open and easier to locate, even if harder to read, and performance-centric designs. What have you learned about the craft of software design which has changed the way you approach coding since leaving the academic world?

• What are some practical uses of generating all permutations of a list, such as ['a', 'b', 'c'] ?

  - by Jian Lin

  I was asked by somebody in an interview for web front end job, to write a function that generates all permutation of a string, such as "abc" (or consider it ['a', 'b', 'c']). so the expected result from the function, when given ['a', 'b', 'c'], is abc acb bac bca cab cba Actually in my past 20 years of career, I have never needed to do something like that, especially when doing front end work for web programming. What are some practical use of this problem nowadays, in web programming, front end or back end, I wonder? As a side note, I kind of feel that expecting a result in 3 minutes might be "either he gets it or he doesn't", especially I was thinking of doing it by a procedural, non-recursive way at first. After the interview, I spent another 10 minutes and thought of how to do it using recursion, but expecting it to be solved within 3 minutes... may not be a good test of how qualified he is, especially for front end work.

• Is Android reference at android.com good enough

  - by the100rabh

  Hi, I am a C++ developer, but have a fair idea of Java as I learnt it in college 5years ago. I have been trying to learn programming for android. But instead of rushing to buy books, I have tried to read through the Android Dev Guide and learn from there making use of the sample applications. Thats besides SO ofcourse. I am trying to make some apps based on ideas I have. So my question is, Is it suitable or possible to learn android programming this way. Or is there something that I will be missing in all this.

• Copying a 2D non-space array to another

  - by Jay

  I'm a total programming newb who started learning java programming this sem at uni. I'm up to a step where i need to copy some elements from one method to another. This program i'm creating is called an L_Game. The question I'm stuck is: the project(Slide other) method should take another slide as a parameter, and copy each non-space cell from this slide into the other slide (i.e. like a projector projecting slides onto a screen. I previously made a constructor with the parameter cells in it and believe i copied it to the project(Slide other) method. But i'm not sure what to do to copy each "non-space cell" With the "for" method or the "if" method? If my question isn't typed correctly or have information missing, please let me know. Any help will be appreciated. (I obviously have no idea with what i'm doing...)

• Must JDBC Resultsets and Statements be closed separately although the Connection is closed afterwards?

  - by Mulmoth

  It is said to be a good habit to close all JDBC resources after usage. But if I have the following code, is it necessary to close the Resultset and the Statement? Connection conn = null; PreparedStatement stmt = null; ResultSet rs = null; try { conn = // Retrieve connection stmt = conn.prepareStatement(// Some SQL); rs = stmt.executeQuery(); } catch { // Error Handling } finally { try { if (rs != null) rs.close(); } catch (Exception e) {}; try { if (stmt != null) stmt.close(); } catch (Exception e) {}; try { if (conn != null) conn.close(); } catch (Exception e) {}; } The question is if the closing of the connection does the job or if it leaves some resources in use.

• Ideas for using R to create a T-shirt design (for useR 2010) ?

  - by Tal Galili

  There is now a competition for creating a T-shirt design for useR2010. Someone proposed the idea to use R for creating the T-shirt image. Which leads me to my questions: What type of images do you think might be fitting for this? How would you suggest to use R to create the images ? Would anyone here want to have a go at it? (p.s: I understand this is not a pure "programming" question. Yet it involves R programming, the understanding of R aesthetics, and some caring for the R community. I also understand I am at the risk of annoying people here with this question, so in case that happens - I deeply apologies! My only justification is that I am acting in good faith and in the purpose of having nice things for R users to enjoy, while learning something in the process) Related thread I once opened: http://stackoverflow.com/questions/2162131/how-can-i-learn-to-create-beautiful-infographics-with-connection-to-my-r-knowled

• wxWidgets - Add items to sizer via DLL

  - by intl

  I have a GUI set up with wxWidgets (C++, MSVC) and part of the functionality is to add elements to the GUI via DLL's. Essentially, I would be passing in a sizer to the DLL which will in turn add the elements based on what is in the DLL. Could someone just point me in the right direction on how to get the DLL set up? I have looked, but don't see anything that's similar to what I'm looking for. The programming of the elements is fine with me, I just need to understand how to structure the DLL programming. Help appreciated.
