II. Compiling and Running the Code

Most of the book's code was designed to be compiled and run from a command prompt. They may also be imported into Microsoft Visual Studio for compilation. Instructions are given here for command line usage:

1. Go to the Microsoft Developer Network Site (http://msdn.microsoft.com/netframework) and download and install the .NET Framework SDK.

2. In .NET Framework versions 2.0 and higher, preconfigured command prompts are available from the Program Menu. Depending on your version you will go to:

Start -> All Programs -> Microsoft .NET Framework SDK v2.0 -> SDK Command Prompt

or:

Start -> All Programs -> Microsoft Windows SDK -> CMD Shell

You can also open a regular windows command prompt and run sdkvars.bat (v2.0 and lower) or SetEnv.Cmd (v3.0 and higher) to set your environment variables. If you are using SetEnv.Cmd you may need to use the /V:ON option when launching your command prompt.

Example of running sdkvars (Note: your sdkvars output may vary):

C:\>sdkvars

C:\>Set Path=C:\Program Files\Microsoft.NET\SDK\v1.1\Bin\;C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\;C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\bin\;C:\Program Files\MicrosoftVisual Studio .NET 2003\Common7\IDE\;C:\Program Files\Microsoft.NET\SDK\v1.1\Bin\;C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\;C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\bin\;C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\IDE\;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\bin;C:\Program Files\Microsoft.NET\SDK\v1.1\Bin

C:\>Set LIB=C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\lib\;"C:\Program Files\Microsoft.NET\SDK\v1.1\Lib\";C:\Program Files\Microsoft Visual Studio.NET 2003\Vc7\lib\;"C:\Program Files\Microsoft.NET\SDK\v1.1\Lib\";

C:\>Set INCLUDE=C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\;"C:\Program Files\Microsoft.NET\SDK\v1.1\include\";C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\;"C:\Program Files\Microsoft.NET\SDK\v1.1\include\";

C:\>Set NetSamplePath=C:\PROGRA~1\Microsoft.NET\SDK\v1.1\

C:\>

3. To compile a single program, use the csc command with the source file name, for example:

C:\>csc IPAddressExample.cs

Microsoft (R) Visual C# .NET Compiler version 7.10.3052.4 for Microsoft (R) .NET Framework version 1.1.4322 Copyright (C) Microsoft Corporation 2001-2002. All rights reserved.

This will create the .exe executable:

C:\>dir

10/22/200303:40 PM
1,629 IPAddressExample.cs
03/12/200411:24 PM
4,096 IPAddressExample.exe

To run a program type the name of the program with a .exe extension or no extension along with any command-line arguments.To run a program type the name of the program with a .exe extension or no extension along with any command-line arguments.

C:\>IPAddressExample www.mkp.com

Local Host:
tractor
192.168.0.2
www.mkp.com:
www.mkp.com
129.35.78.178

To compile a single executable from several source code files, enter all the files on the same csc command:

C:\>csc SendTcp.cs ItemQuote.cs ItemQuoteEncoder.cs ItemQuoteEncoderText.cs ItemQuoteTextConst.cs ItemQuoteDecoder.cs ItemQuoteDecoderBin.cs ItemQuoteBinConst.cs

Microsoft (R) Visual C# .NET Compiler version 7.10.3052.4 for Microsoft (R) .NET Framework version 1.1.4322 Copyright (C) Microsoft Corporation 2001-2002. All rights reserved.

4. Batch files are supplied (ch2.bat, ch3.bat, ch4.bat and ch5.bat) to compile all the code for each chapter, typing the batch file name on the command prompt will compile all programs in the chapter's directory:

C:\>ch2

Note: Some of the programs in Chapters 4 and 5 utilize source files from earlier chapters, as described in the download section. The batch files for Chapters 4 and 5 will automatically look for these files in the appropriate chapter directory. You will need to download the entire archive or all required chapter zip files for these programs to compile correctly.

III. Errata

• In version 2.0 of the .NET Framework the System.Net.Dns.Resolve()and System.Net.Dns.GetHostByName() methods were deprecated and replaced bySystem.Net.Dns.GetHostEntry(). These methods were referenced in the followingfiles:
  
  IPAddressExample.cs, TcpEchoClientSocket.cs, UdpEchoClientTimeoutSocket.cs,TcpEchoPeekClient.cs, TcpNBEchoClient.cs, TcpPollEchoClient.cs,and TcpEchoClientAsyncSocket.cs
  
  The following v2.0 versions of these files were created using GetHostEntry():
  
  IPAddressExample2.cs, TcpEchoClientSocket2.cs, UdpEchoClientTimeoutSocket2.cs,TcpEchoPeekClient2.cs, TcpNBEchoClient2.cs, TcpPollEchoClient2.cs,and TcpEchoClientAsyncSocket2.cs.



• Page 51, line 13, this line of code:
  
  Console.WriteLine("echoed {0} bytes.", totalBytesRcvd);
  
  Should read:
  
  Console.WriteLine("echoed {0} bytes.", totalBytesEchoed);
