I am explaining how to connect to Borland StarTeam Version Control System programmatically using C# console application and checkout files to local machine.

1. C# and Borland-StarTeam Connectivity
Here I will explain-
 What is Version ControlSystem.
 What is Borland StarTeam.
 How to connect to Borland StarTeam fromC# and Check Out Files to local
machine.
Version Control System:
 Version Control is a systemthat records changes to a file or set of files over
time so that you can recall specific versions later.
 A version controlsystemis mostly based around one concept, tracking
changes that happen within directories or files.
 Ithelps teams to coordinate more effectively and team members to work in
parallel.
 With version control systems you can do things like-
1. File Locking.
2. Branching and Merging.
3. Reverting back to older version of files.
For more information on version control please refer to this LINK.
Borland StarTeam
 StarTeam is a versioncontrol system used in softwaredevelopment,
especially when a projectinvolves multiple teams in different locations.
 StarTeam is created by StarbaseCorporation, which was acquired by
Borland in January 2003 which was acquired by Micro Focus after some
time.
 StarTeam supports allthese features- branching and three-way merging,
difference analysis, advanced user access and security management,
checkpoints, end user and administrator auditing, view and revision labels,
promotion states and customization features.

machine
Now I will explain how you can connect to Starteam from C# and checkout the
files.
Few points to note-
 StarTeam is a licensed product.you can register for a trial license here.
 After registration you will get a usernameand password which you can use
to download .Net SDK for StarTeam.
 SDK defers for the server version you are using. HereI am focusing on
StarTeam 2008 R2 which supports st-sdk-10.4.8.57-net-win.
 With SDK you will get sampleapplication which you can refer to work on
your application.
 Itwill create a help file by the name StarTeamSDK for .NET.chm
Now it is coding time ----------->I am writing a console application
//Create a console application
//Add reference to the dlls as shown below.
//These dlls you will get after installing SDK
using System;

3. using System.Collections.Generic;
using System.Linq;
using System.Web;
using StarTeam;
public class StarTeamHelper
{
//Declare Needed variables
//Indicates that all item types should be displayed.
public conststring ALL_TYPES = "*";
//Indicates that all views should be searched.
public conststring ALL_VIEWS ="*";
//Server TCP/IP address -- server fromwhich you wantto checkout files
private string m_strServer = "servername";
//Server port number
private int m_nPort= “PortNumber”;
//Logon user name --usernameto login to the server
private string m_strUser = "username";
//Logon password
private string m_strPassword ="password";

4. //Project name; null searches all projects
private string m_strProject= null;
//View name; null searches default view
private string m_strView = null;
//Folder path; null searches the root folder
private string m_strFolder = null;
//true if subfolders aresearched recursively
private bool m_bRecursive= true;
//List items last modified since this date
private DateTime m_cutoffDate = DateTime.Now;
//True to filter by m_cuttoffDate

public static void Main(string[] args)
{
//Create the Server object.
Server stServer = new Server(m_strServer, m_nPort);
//LogOn to the server.
stServer.LogOn(m_strUser, m_strPassword);

5. // For each project on this server ...--itwill give list of projects to which we
have access
foreach (ProjectstProject in stServer.Projects)
{
// If no projectname was specified, search all projects.
if (m_strProject== null)
{
//use default view
View stView = stProject.DefaultView;
//To check out files we need to take help of CheckoutManager class
//create CheckoutManager object
CheckoutManager objCheckoutManager =
stView.CreateCheckoutManager();
//if file to be checked out with an exclusive lock
//(so no one else could checkout it while it is checked out).
objCheckoutManager.Options.LockType=Item.LockType.EXCLUSIVE;
/**********CHECKING OUTSINGLEFILE***************/
//By default, startsearching fromthe root folder.
Folder stFolder = stView.RootFolder;

6. //To check out single file useStarTeamFinder class's FindFile method
to find your file
//Syntax:File StarTeamFinder.FindFile(Folder source, string name, bool
matchCase);
File file = StarTeamFinder.FindFile(stFolder, "YourFileName", false);
//create the Target File
System.IO.FileInfo objFileInfo =new
System.IO.FileInfo("D:TargetFIle");
//Finally CHECK OUT the File
objCheckoutManager.CheckoutTo(file, objFileInfo);
/***********CHECKING OUT MULTIPLEFILES************/
/*Folder stFolder = stView.FindByName("FolderName",
true).RootFolder;
ItemCollection stItem= stFolder.GetItems("File");
//checks out file to default working folder. Wecan see this default
working folder using starteam client
objCheckoutManager.Checkout(stItem);*/
}
}
// Finally Disconnectfromserver.
stServer.Disconnect();
