1. Install DotPeek If you have not setup and install .Net Peek, please do so now from here . 2. Setup Symbol server Next setup your Visual Studio IDE. I'm using VS2015. Goto Tool->Optoins->Debugging 1. Uncheck - Enable Just My Code 2. Check - Enable source server support.

Please create a new file and paste the following codes in it.     class Samurai     {         readonly ...

This is my attempt to get you started with scala combinator parser. It is a very powerful tool that allows you to create your own lexical analysis similar to yacc and other lexer. Area of application includes a) calculator that accept input string as follow "3+2" b) match specific text in a given string like finding "fox" in the string "the brown fox jump over the fence" I'm going to use an example from reference below. Here we are trying to extend our SimpleParser from RegexParser and defined a function called "word" that is basically a regex itself with the purpose of matching a single word. Simple Parser This code is taken from https://wiki.scala-lang.org/ import scala.util.parsing.combinator._ class SimpleParser extends RegexParsers { def word : Parser[ String ] = """[a-z]+""" .r ^^ { _.toString } } In code above, """ means it is a regex.   ^^ mean if  a match is found,...

I found the easiest way to convert your instance to/from json in Playframework is to use the following code: For type instance I'm just making use of Json.writes and Json.reads to do the dirty work. case class CartProduct(id : String , qty : Double ) object CartProduct { implicit val cartProductWrites = Json. writes [CartProduct] // convert to json implicit val cartProductReads = Json. reads [CartProduct] // example - get from post } The code below works too, but a bit too long for me. implicit val cartProductReads : Reads[CartProduct] = ( (JsPath \ "id" ).read[ String ] and (JsPath \ "qty" ).read[ Double ] )(CartProduct. apply _) Somewhere in your controller, you might have the following code to write your instance in json format. def getProduct (productId : String ) = Action { val p = new Product( "Demo" , "Demo App" , 12.0 ) Ok (Json. toJson (p)) } To get back your instance from a HTTP post def...

To debug your application with IntelliJ is pretty straight forward. Setup command prompt  1. Run the following command $ activator - jvm - debug 9999 2. You will probably see something like this Listening for transport dt_socket at address : 9999 3. Wait for the command prompt to appear and type  " Run " - If you have your application running, please stop the running process. Setting up your IntelliJ  1.In your IDE, goto Run -> Edit Configuration. Add " Remote " and configure the port to point to 9999.  Example of your configuration could look something like this. Save this configuration. Then run your remote debug configuration and at this point you would need to set your breakpoints. Open up your browser and go to "localhost:9000" and you will hit your breakpoint.

If you're trying to debug through ASP.Net MVC / WebAPI to see how it all glued together, you probably need to download and build it locally from here . You should probably know that, ASP.Net MVC on github runs on DNX. and you need to either install VS2015 Web Developer Tools or set it up manually by following this guide . If you face reference issue, for example Unable to Reference DNX 4.5.1 or DNX Core 5.0, you probably have an installation issue with your VS2015 installation.  Setup your DNX to the latest version and then reinstall VS2015. Yep i think it is stupid but it happened to me. You can always goto the ASP.Net MVC git clone folder to run "build " manually. If you can  build that successfully, then all you have have to do is reinstall VS2015 and then open and build the project using VS2015. After a successful build, you can run a test project to see if ASP.Net MVC is working properly. To test it, run MvcSample.Web project by right clicking it a...

A quick and dirty way of generating SqlException class SqlExceptionGenerator     {         public static void ThrowException(SqlConnection con)         {             con.Open(); // should be a valid connection             SqlCommand cmd = new SqlCommand("raiserror(50005, 16, 1)", con);             cmd.ExecuteNonQuery();         }     }

The spark documentation doesn't says (or maybe i missed it) about getting sbt tool if you're trying to build it on Windows. You need this to build, package and run scala code in spark. This tool can be obtained here . Once you have this installed, you can fire up your command / cygwin command prompt and continue building, packing and running your code by following this guide . basically it is just running sbt assembly .

There is an easy fix for this issue. (hopefully you didn't try to install VS2008 or Windows SDK),  All you have to do is create the missing directory as stated by blogger here :- http://frazzleddad.blogspot.com/2010/04/fixing-invalid-search-path-for-lib.html

After placing my hibernate entity in a different jar file, i notice that some of my tables are not created.

I don't know why am i even compiling Plaid for, maybe it can be a cool language to try out. Anyway, the site documentation works, just that there are a few glitches that i need to handle when compiling for Windows. As stated in the documentation, go 1. Grab TortoiseSVN 2. Check out the source https://code.google.com/p/plaid-lang/ , into a directory of your likings, let's say c:\java\plaid 3. Include the followings in your path : C:\java\plaid\fastbuilder;C:\java\plaid; 4. Goto C:\java\plaid\tests and run ant build . You should be able to compile successfully. 

I was amazed how easy it is to build S park on Windows. Just have to 1. Download and install Scala 2.9.2. Ensure your SCALA_HOME is accurately setup. 2. Also make sure you have javac available in your environment path. 3. Download spark (0.7.0). Spark uses sbt (simple build tool and it is shipped together with the code. After you extracted spark source code, goto the root folder and run sbt/sbt package And you're done! Awesome.

When you are loading your jquery UI tab in your browser and at the same time you enable your firebug, you might run into this problem - ajax options is null. No immediate fixes, just gotta turn off your firebug during jquery ui tab loading process. :(

Spring MVC exception handling gets easier with @ControllerAdvice with the release of Spring 3.2.1. You can annotate your class as shown below and add a method to handle exception @ControllerAdvice public class AppCoreController { @ExceptionHandler(Exception.class) public @ResponseBody RequestStatus handleException(Exception exception) { RequestStatus errorStatus = new RequestStatus(); errorStatus.setMessageCode(-999); errorStatus.setMessageDescription(exception.getMessage()); return errorStatus; } } Please note that RequestStatus is a custom controller and yeap we are returning an class / object type as oppose to just String data type.  These add exception handling capabilities to all your existing controller.
