• POS Desktop Application using DB or Localfiles ? using WPF

  - by Panindra

  I am planning to build a POS Application for my shop. I have enough knowledge to build the application using DB and also using local files( system.IO - binary files ) to store and access the data for my application. But , i have no deployment experience and confused in choosing data storing option. Database using MDF may be good option ( may ease plenty of coding ) but i don't want to have SQL server on my desktop. as i am using WPF for building , my concern is that my application may get slow due to server response and design rendering of WPF. Then i tried to use only local data (binary files) to store the data and retrive using class and objects. but this coding is taking lot of time , so in the middle of the process i struck in the dilemma of going back to Database . Please help , for performance wise whic one is better . and in Practical World ,in professional applications which one is widely using .. please give suggestions ..

• Auto-complete/suggestion popup menu in GtkTextView

  - by Tyler

  I'm trying to create a system that will allow me to respond to the current text and auto-complete/suggest what should come next. For example if the user starts to type "Batm" then the system would respond with a menu showing the full completed word "Batman". Think of an IDE like Eclipse or Visual Studio and you get the idea. I understand how to create a popup menu in Gtk+ but what I don't understand is the following: How do I grab the word that the user is currently typing from a GtkTextView (or SourceView) so that I can do a lookup and offer suggestions? How do I position the menu in such a way that it sits next to the current text item (like it would in an IDE)? If anyone could offer suggestions or even a link to a tutorial or example on how to do this correctly I would be forever grateful. As always thanks for you help! Programming language: C

• How to manage toolbars with mvvm and WPF

  - by Michael Stoll

  I'm looking for a smooth method of managing toolbars (and menus) with mvvm in WPF. Consider an UI with tabbed workspaces and heterogenous content (like Visual Studio). There the toolbars should be hidden or visible depending on the active tab. How would you design the view viewmodel for the toolbars? I'd use a collection of toolbar-viewmodels and bind the ToolbarTray to it, but afaik that's not possible. Any recommendations are apreciated. Links to samples, best practice papers, etc. are welcome.

• New to javascript, why is jQuery such a beast?

  - by gnucom

  Hey Everyone, I'm new to javascript (functional programming is okay for me, though) and I am wondering how jQuery got away with some of the design decisions they made. Is it just too much work to fix now or what? For instance, there seems use of strange symbols in strings when accessing elements in the DOM or weird function definitions for $, that are forcing me to check references every other time I want to get some basic data. Can someone point me to a learning source where I can learn all of these nuances of jQuery (jQuery's examples just don't cut it, they're too spread out)? Maybe someone has a super good reference site/pdf for jQuery? Thanks

• Large tables of static data with DBGhost

  - by Paulo Manuel Santos

  We are thinking of restructuring our database development and deployment processes by using DBGhost, we want to move away from the central development database and bring the database to the source control. One of the problems we have is a big table with static data (containing translated language strings), it has close to 200K rows. I know that our best solution is to move these stings into resource files, but until we implement that, will DbGhost be able to maintain all this static data and generate our development and deployment databases in a short time? And if not is there a good alternative to filling up this table whenever we need to?

• What's the performance penalty of weak_ptr?

  - by Kornel Kisielewicz

  I'm currently designing a object structure for a game, and the most natural organization in my case became a tree. Being a great fan of smart pointers I use shared_ptr's exclusively. However, in this case, the children in the tree will need access to it's parent (example -- beings on map need to be able to access map data -- ergo the data of their parents. The direction of owning is of course that a map owns it's beings, so holds shared pointers to them. To access the map data from within a being we however need a pointer to the parent -- the smart pointer way is to use a reference, ergo a weak_ptr. However, I once read that locking a weak_ptr is a expensive operation -- maybe that's not true anymore -- but considering that the weak_ptr will be locked very often, I'm concerned that this design is doomed with poor performance. Hence the question: What is the performance penalty of locking a weak_ptr? How significant is it?

• can QuickGraph support these requirements? (includes database persistence support)

  - by Greg

  Hi, Would QuickGraph be able to help me out with my requirements below? (a) want to model a graph of nodes and directional relationships between nodes - for example to model web pages/files linked under a URL, or modeling IT infrastructure and dependencies between hardware/software. The library would include methods such as * Node.GetDirectParents() //i.e. there could be more than one direct parent for a node * Node.GetRootParents() //i.e. traverse the tree to the top root parent(s) for the given node * Node.GetDirectChildren() * Node.GetAllChildren() (b) have to persist the data to a database - so it should support SQL Server and ideally SQLite as well. If it does support these requirement then I'd love to hear: any pointers to any parts of QuickGraph to dig into? what is the best concept re it's usage in terms of how to use database persistence - is it a simpler design to assume every search/method works directly on the database, or does QuickGraph support smarts to be able to work in memory and the "save" to database all changes at an appropriate point in time (e.g. like ADO.net does with DataTable etc) Thanks in advance

• C#: Why only integral enums?

  - by JamesBrownIsDead

  I've been writing C# for seven years now, and I keep wondering, why do enums have to be of an integral type? Wouldn't it be nice to do something like: enum ErrorMessage { NotFound: "Could not find", BadRequest: "Malformed request" } Is this a language design choice, or are there fundamental incompatibilities on a compiler, CLR, or IL level? Do other languages have enums with string or complex (i.e. object) types? What languages? (I'm aware of workarounds; my question is, why are they needed?) EDIT: "workarounds" = attributes or static classes with consts :)

• Displaying same image multiple times at different locations in a web page using JavaScript or CSS

  - by Joe B

  I’m looking to create a web page with 6 coupons on it, two per line in a web space of 1275 X 1650. Each coupon space will consist of a different image. The problem is I will be creating 20 such web pages that will have these coupons on them. Now some of the same images will appear in different locations/positions on the various web pages. Is there a way to update the same image that appear in different locations/positions at the same time? And what language is used to complete this? I’ve tried CSS but it don’t think it’s possible. So should I be using JavaScript.

• Java - how to tell class of an object?

  - by lkm

  Given a method that accepts as a parameter a certain supertype. Is there any way, within that method, to determine the actual class of the object that was passed to it? I.e. if a subtype of the allowable parameter was actually passed, is there a way to find out which type it is? If this isn't possible can someone explain why not (from a language design perspective)? Thanks Update: just to make sure I was clear void doSomething(MyType myType) { //determine if myType is MyType OR one of its subclasses } Since the method signature specifies the parameter as being MyType, then how can one tell if the object is actually a subtype of MyType (and which one).

• Latest 100 mentions - Twitter api

  - by laurens

  I'm looking to achieve the following: For a specific person, for example BarackObama, I'd like to get the last 100 times/tweets he was mentioned. Not his own tweets but the tweets of others containing @BarackObama. In the end I'd like to have: the person who mentioned, location, datetime. This content should be written to a flat file. I've been experimenting with the Twitter API and Python, with success but haven't yet succeeded achieving the above problem. I know there is a dev sections on the twitter website but they don't provide any example of code!! https://dev.twitter.com/docs/api/1/get/statuses/mentions count=100 .... For me the scripting language or way of doing is not relevant it's the result. I just read on the internet that python and Twitter api are a good match. Thanks a lot in advance!!

• Ask about the copyright of develop destop application based on web application

  - by Nano HE

  Hi, I googled and found some web online caculators (such as BodyFatCalculator & CaloricCalculator). I plan to develop the desktop Caculators in C#(WPF & .net 3.5). But I would test the online function and build my application module (I think some body properties not suit for asian people, maybe I still need do more research.). But now I must study others web app before my destop app design. Could I develop my app without the web application owner's permission? Thank you.

• Store interface in array list java

  - by agazerboy

  Hi all, I am learning java. I am trying to use composite design pattern. I am trying to use following logic. ( Don't laugh I know it is very basic :) ) Item -> interface Folder -> class File -> class In folder class, can I create an arraylist of Item to store files information? ArrayList<Item> info = ArrayList<Item>(); Or should I use Folder Arraylist? ArrayList<Folder> info = ArrayList<Folder>(); I don't know if interface can store real data as there is no variable just function definitions. Thanks for helping a newbie :)

• What good timesheet should and shouldn't have for a small (non programming) 50 people company?

  - by MadBoy

  I'm sure most people here had to fill at least one time sheet in their life that made their life miserable, hell it's even the worst time taker ever especially after you have to fill it in hurry. I will be developing some simple TimeSheet application for a small company of 50 people (non programming related, it's actually 4 companies working together) and would like it to be user friendly and as less disturbing as possible. So what in your opinion makes it a good timesheet (lack of it doesn't count :p), what data it should store? Should be only hours per day with possibility to choose project, company and simple overview what you have worked on like: Day 1, 3:00, 'Company 1', 'Project5', 'Name', Short Overview Day 1, 5:00, 'Company 2', 'Project6', 'Name', Short Overview Or should it gather more data? Would it be realy bad if it were an WinForms application considering that I don't know ASP.NET or any other web based language? I would be deploying it using ClickOnce or so.

• How created method with signature as List

  - by London

  Hi all, I'm very new to Java programming language so this is probably dumb question but I have to ask it because I can't figure it out on my own. Here is the deal. I want to create method which extracts certain object type from a list. So the method should receive List as argument, meaning list should contain either Object1 or Object2. I've tried like this : public Object1 extractObject(List<?>){ //some pseudo-code ... loop trough list and check if list item is instance of object one return that instance } The problem with declaring method with List<?> as method argument is that I receive compilation error from eclipse Syntax error on token ">", VariableDeclaratorId expected after this token. How do I set the method signature properly to accept object types either Object1 or Object2 ? Thank you

• Suggest resources for learning Scheme.

  - by EmFi

  I'll be starting a new job soon where Scheme is heavily used. I currently do not know Scheme, but my employer assures me that is not a problem. Regardless I'd like to hit the ground running and have a working knowledge of the language before my start date. So I'm looking for good resources from which to learn Scheme. I have had minimal exposure to functional languages. Really only a small chunk of a course devoted to Haskell. But I have a strong background in procedural and OO and procedural languages. Before it gets requested by a commenter, I am competent with the following languages: C, C++, C#, Java, Perl, Python, and Ruby.

• Import de-normalized relational data from Excel into SQL Server

  - by roryf

  I need to import data from an Excel spreadsheet into SQL Server, but the data isn't in a relational/normalized format so the import wizard isn't going to cut it (as far as I know). The data is in this format: Category SubCategory Name Description Category#1 SubCategory#1 Product#1 Description#1 Category#1 SubCategory#1 Product#2 Description#2 Category#1 SubCategory#2 Product#3 Description#3 Category#1 SubCategory#2 Product#4 Description#4 Category#2 SubCategory#3 Product#5 Description#5 (apologies I'm lacking the inventiveness to come up with 'real' data at this time in the morning...) Each row contains a unique product, but the cateogry structure is duplicated. I want to import this data into three tables: Category SubCategory Product (I know SubCategory should really be contained within Category, DB was not my design) I need a way to import unique rows based on the Category and then SubCategory columns, and then when importing the other columns into Product, obtain a reference to the SubCategory based on name. Short of scripting this, is there any way to do it using the import wizard or some other tool?

• I need to do a BASICE For Loop algorithm for a java Pyramid

  - by user1665119

  Question 2. USE THE FOR LOOP. Design and write an algorithm that will read a single positive number from the keyboard and will then print a pyramid out on the screen. The pyramid will need to be of a height equal in lines to the number inputted by the operator. Your program is not to test for negative numbers, nor is it to cater for them. For your test, use the number 7. If you would like to take the problem further, try 18 and watch what happens. Example input: 4 Example output: 1 121 12321 1234321

• Rails 3 routes and using GET to create clean URLs?

  - by Hard-Boiled Wonderland

  I am a little confused with the routes in Rails 3 as I am just starting to learn the language. I have a form generated here: <%= form_tag towns_path, :method => "get" do %> <%= label_tag :name, "Search for:" %> <%= text_field_tag :name, params[:name] %> <%= submit_tag "Search" %> <% end %> Then in my routes: get "towns/autocomplete_town_name" get "home/autocomplete_town_name" match 'towns' => 'towns#index' match 'towns/:name' => 'towns#index' resources :towns, :module => "town" resources :businesses, :module => "business" root :to => "home#index" So why when submitting the form do I get the URL: /towns?utf8=?&name=townname&commit=Search So the question is how do I make that url into a clean url like: /towns/townname Thanks, Andrew

Note that I have two values in this .resx file I added at design time. Thanks Gerry

• IE 8 Chinese encoding characters

  - by digitalbart

  Hello, I am unable to render Chinese characters in IE 8. I have researched this and I am aware of the meta tag to force compatibility mode. I am also aware of the language pack you can install. Finally I have seen that Microsoft actually forces IE7 compatibility mode on their Chinese website. http://www.microsoft.com/zh/cn/default.aspx I am wondering if anyone has any alternatives solutions to this problem. None them seem that appealing to me. I am using utf8 as my encoding and this problem only occurs in IE8. Thanks
