Windows XP supports multiple keyboards, but by default, the .Net Framework will treat them all as one. This article explains how to use the Windows API Raw Input methods to support multiple keyboards from a C# application.
using System.Reflection;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;

// General Information about an assembly is controlled through the following 
// set of attributes. Change these attribute values to modify the information
// associated with an assembly.
[assembly: AssemblyTitle("Input")]
[assembly: AssemblyDescription("")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("HOME")]
[assembly: AssemblyProduct("Input")]
[assembly: AssemblyCopyright("Copyright © HOME 2008")]
[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]

// Setting ComVisible to false makes the types in this assembly not visible 
// to COM components.  If you need to access a type in this assembly from 
// COM, set the ComVisible attribute to true on that type.
[assembly: ComVisible(false)]

// The following GUID is for the ID of the typelib if this project is exposed to COM
[assembly: Guid("5be6ca17-5dd1-4881-94cc-3984cc8d65e2")]

// Version information for an assembly consists of the following four values:
//
//      Major Version
//      Minor Version 
//      Build Number
//      Revision
//
// You can specify all the values or you can default the Revision and Build Numbers 
// by using the '*' as shown below:
[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]

Emma's first steps in programming took place at primary school over thirty years ago, thanks to a TI-99/4A and the LOGO language. Following a Master's degree in English Studies (obtained, strangely enough, with a paper on the birth of the microcomputer), Emma started her career in IT.

Over the last ten years, she has worked as a localiser, technical writer, editor, web designer, systems administrator, team leader and support engineer, before finally making the move into software development a few years ago. She is now thrilled on a daily basis that she is getting paid for writing code after doing it for free half her life!
