Language (How Do I in Visual J# Express) 

This page links to help on widely used J# language tasks. To view other categories of popular tasks covered in Help, see How Do I in Visual J# Express.

• Getting Started with Visual J# Express
  Provides some suggestions for getting started in Visual J#.

Java and J#

• How to: Use the Try/Catch Block to Catch Exceptions
  Contains a code example that uses a try-catch block to catch a possible exception.

• How to: Create Enumerated Constants
  Describes how J# enables you to create your own data types using the enum keyword.

• How to: Convert Java-Language Bytecode to MSIL Code
  Describes how you can quickly convert many legacy Java applications to Visual J#.

• Supplemental UI Library
  Provides supplemental library support for more information about applets.

J# and .NET

• How to: Implement an Interface in J#
  Explains how the implements keyword enables your class to declare methods with the same signature as the interface and then implement them.

• How to: Use Specific Exceptions in a Catch Block
  Explains that you should put catch blocks targeted to specific exceptions before a general exception catch block or the compiler might issue an error.

• Attaching Attributes
  Explains how to use Visual J# to attach attributes to classes, fields, methods, parameters, and other programming elements.

• Calling Methods That Take Arguments By Reference
  Describes how Visual J# follows the C++ style where you can directly call the method and pass the parameter just like in the normal case, and the Visual J# compiler does the conversion implicitly.

• Defining and Using Properties
  Suggests you use Visual J# to access properties defined in .NET Framework classes. Visual J# translates properties in .NET Framework classes to the accessor methods: get_ and set_.

• Definition and Use of Events
  Explains that Visual J# allows you to register for events published by .NET Framework classes.

• Using Enumerations
  Suggests you use enumerations defined in the .NET Framework or other user-defined assemblies with the J# compiler.

• Calling Methods That Take Arguments By Reference
  Describes how Visual J# follows the C++ style where you can directly call the method and pass the parameter just like in the normal case and the Visual J# compiler does the conversion implicitly.

• Common Language Specification Compliance Checking
  Explains that for a given type to be used by other languages, it must be compliant with the CLS.

Exceptions

• Exception Handling Fundamentals
  Contains suggestions on best practices for handling exceptions.

• Handling and Throwing Exceptions
  Provides an overview on exception handling using the .NET Framework and Visual Studio, including best practices.

• How to: Use the Try/Catch Block to Catch Exceptions
  Uses a try-catch block to catch a possible exception

• How to: Use Specific Exceptions in a Catch Block
  Puts catch blocks targeted to specific exceptions before a general exception catch block or the compiler might issue an error.

Reflection

• Reflection Overview
  Provides conceptual information about reflection and links for using it.

Accessing Native Functions

• Calling Native Methods
  Explains how you can use the platform invocation services provided by the common language runtime to call into native code.

• How to: Call a Method in a DLL from Visual J#
  Includes an example that shows you how to call both static and dynamic methods from the vjslib.dll library.

• PInvoke Sample (Call Unmanaged APIs)
  Demonstrates how Visual J# can use the platform invoke services provided by the common language runtime to call unmanaged APIs.

Standards and Conventions

• How to: Compile a Java-language Application in Visual J#
  Shows you how to create your own project, add your existing .java files, and compile them with J#.

• Common Language Specification Compliance Checking
  Explains that the compiler provides support for checking types for compliance with the Common Language Specification (CLS).
