• Top 10 Essential Application Programming Interface (API's)

  Web Service Application Programming Interface (API) is an interface implemented by a software program to enable interaction with other software, similar to the way a user interface facilitates interaction between humans and computers. The API (Application Programming Interface) has been an essential component for creating applications that hook into or utilize web apps such as Facebook and Flickr.

• Combobox binding with different types

  - by George Evjen

  Binding to comboboxes in Silverlight has been an adventure the past couple of days. In our framework at ArchitectNow we use LookupGroups and LookupValues. In our database we would have a LookupGroup of NBA Teams for example. The group would be called NBATeams, we get the LookupGroupID and then get the values from the LookupValues table. So we would end up with a list of all 30+ teams. Our lookup values entity has a display text(string), value(string), IsActive and some other fields. With our applications we load all this information into the system when the user is logging in or right after they login. So in cache we have a list of groups and values that we can get at whenever we want to. We get this information in our framework simply by creating an observable collection of type LookupValue. To get a list of these values into our property all we have to do is. var NBATeams = AppContext.Current.LookupSerivce.GetLookupValues(“NBATeams”); Our combobox then is bound like this. (We use telerik components in most if not all our projects) <telerik:RadComboBox ItemsSource="{Binding NBATeams}”></telerik:RadComboBox> This should give you a list in your combobox. We also set up another property in our ViewModel that is a just single object of NBATeams  - “SelectedNBATeam” Our selectedItem in our combobox would look like, we would set this to a two way binding since we are sending data back. SelectedItem={Binding SelectedNBATeam, mode=TwoWay}” This is all pretty straight forward and we use this pattern throughout all our applications. What do you do though when you have a combobox in a ItemsControl or ListBox? Here we have a list of NBA Teams that are a string that are being brought back from the database. We cant have the selected item be our LookupValue because the data is a string and its being bound in an ItemsControl. In the example above we would just have the combobox in a form. Here though we have it in a ItemsControl, where there is no selected item from the initial ItemsSource. In order to get the selected item to be displayed in the combobox you have to convert the LookupValue to a string. Then instead of using SelectedItem in the combobox use SelectedValue. To convert the LookupValue we do this. Create an observable collection of strings public ObservableCollection<string> NBATeams { get; set;} Then convert your lookups to strings var NBATeams = new ObservableCollection<string>(AppContext.Current.LookupService.GetLookupValues(“NBATeams”).Select(x => x.DisplayText)); This will give us a list of strings and our selected value should be bound to the NBATeams property in our ItemsSource in our ItemsControl. SelectedValue={Binding NBATeam, mode=TwoWay}”

• .NET – ArrayList hidden gem

  - by nmgomes

  From time to time I end-up finding really old hidden gems and a few days ago I found another one. IList System.Collections.ArrayList.ReadOnly(IList list) This amazing method is available since the beginning (.NET 1.0). I always complain about the small support for ReadOnly lists and collections and I have no clue why I miss this one. For those of you that have to maintain and extend legacy applications prior to ASP.NET 2.0 SP2 this could be a very useful finding.

• What's about Java?

  - by Silviu Turuga

  What is Java? In very short words, Java is a programming language that let you make an application that can be run on different operating systems, no matter we are talking about Windows, Mac OS, Linux or even embedded devices, such as RaspberryPi. When you compile a Java program, instead of getting a binary output as you get on other programming languages, you'll get a Java intermediate code, called Java bytecode. This is interpreted at run time, by a virtual machine that is specifically for the hardware and operating system you are using. What Java do i need? There are 5 major versions of Java: Java SE(Standard Edition) - this is what I'll use on most of my tutorials. Most of the examples will run on Java 6, but for others you'll need Java 7. Java EE (Enterprise Edition) - used for enterprise development Java ME (Micro Edition) - for running Java on mobile and different embedded devices such as PDAs, TV set-top boxes, printers, etc. Java Embedded - for some embedded devices such as Raspberry Pi, where the resources are limited JavaFX - to develop rich content User Interfaces. This is also something that will use a lot. More detailed information can be found on Oracle's website If you just want to run java applications you'll need the JRE (Java Runtime Environment) installed. If you want to program and create new applications, then you'll need the JDK (Java Development Kit).  How to check if Java is already installed? From command line, if you are on Windows, or from Terminal on Mac enter the following: java -version You should get something like this, if you have java installed on your system: java version "1.6.0_37" Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909) Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode) Note: your current Java version might be different from mine. More information https://www.java.com/en/download/faq/whatis_java.xml http://en.wikipedia.org/wiki/Java_(programming_language) Next steps Install Java SDK Chose an IDE. I recommend NetBeans as it is very easy to use and also let you quickly create the GUI of your application Alternatives are Eclipse, Komodo Edit (for Mac), etc. There are plenty of solutions both free or paid.

• Clicking links in pdfs opened with Okular opens Abiword (instead of the default browser)

  - by Marius Hofert

  I work with Xubuntu 12.04 and use Okular (version 0.14.3) to view pdf files. If I click a link in a pdf file (created with pdflatex using the hyperref package), Abiword is opened instead of my default browser google-chrome. How can I change this behavior? The settings in Okular do not seem to provide a solution. (Note that I set google-chrome as the preferred application for web browsing under Settings - Preferred Applications, so that's not the problem).

• Sync profile/data/software for multiple computers?

  - by ultimatebuster

  Is it possible to sync all the user settings (interface settings, program settings), as well as programs for multiple computers? Data is not as important, though the settings (which is technically data, but not that kind of data, like music, files...) and applications are. Also, it will not sync the drivers. (Example: 1 computer uses bumblebee and the other uses ATI catalyst, and maybe there's different network drivers.. etc.)

• How do I "print" to a PostScript file from LibreOffice Write?

  Using OpenOffice with 10.04 I was able to print to a Postscript file, but I find I can't do this with LibreOffice and 12.04 - print-to-file goes to PDF. I want this feature so that I can use a FinePrint-like tool called fprint to print .PS files in booklet form. When I print from other applications I'm offered the usual choice of printers, including print to .PS, but LibreOffice restricts my choice.

• When is it reasonable to create my own programming language?

  - by Daniel Rikowski

  Are there types of killer applications, classes of algorithmic problems, etc., where it is better, in the long run, to create my own language? PS: Just to be sure, I mean a new programming language and a compiler, not a new compiler for an existing language. EDIT: Thank you for the answers. Can you provide some examples, where it is absolutly unnecessary to create a DSL or cases in which a DSL might be a good idea?

• What does 'Nightly Builds' mean?

  - by dbramhall

  I have been using open source projects for a while and been developing upon the open source applications and every so often I come across the words 'Nightly Build' and I have always been curious as to what it actually means. Does it literally mean the projects are done purely as side projects (usually at night after everyone has finished their day jobs) and there's no true contributor/dedicated development team or is it more complex than that?

• T-SQL Tuesday #19: Blind Spots

  - by merrillaldrich

  A while ago I wrote a post, Visualize Disaster , prompted by a real incident we had at my office. Fortunately we came through it OK from a business point of view, but I took away an important lesson: it’s very easy, whether your organization and your team is savvy about disaster recovery or not, to have significant blind spots with regard to recovery in the face of some large, unexpected outage. We have very clear direction and decent budgets to work with, and the safety and recoverability of applications...(read more)
