Connecting to a VS Team Foundation Server and fetching Work Item Details

1. Download the VS TFS SDK (http://msdn2.microsoft.com/en-us/library/bb130146%28VS.80%29.aspx) or install the Visual Studio Team Suite. This will install the necessary assemblies required to access the VS TFS.
2. Create a new VS 2005 Project.
3. Browse to the following path (\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies) and add the following references
   
   -using Microsoft.TeamFoundation;
   -using Microsoft.TeamFoundation.Common;
   -using Microsoft.TeamFoundation.Client;
   -using Microsoft.TeamFoundation.WorkItemTracking.Client;
4. Use the following code to access the VS TFS:
   
   TeamFoundationServer tfs = null;
   WorkItemStore wis = null;
   
   tfs = new TeamFoundationServer(tfsName, CredentialCache.DefaultCredentials);
   tfs.Authenticate();
   // Display the details about the TeamFoundationServer.
   richTextBox1.Text = "Team Foundation Server details:";
   richTextBox1.Text += " \n Server Name: " + tfs.Name;
   richTextBox1.Text += " \n Uri: " + tfs.Uri;
   richTextBox1.Text += " \n AuthenticatedUserDisplayName: " + tfs.AuthenticatedUserDisplayName;
   richTextBox1.Text += " \n AuthenticatedUserName: " + tfs.AuthenticatedUserName;
5. To Access the Projects inside the TeamFoundationServer:
   
   wis = (WorkItemStore)tfs.GetService(typeof(WorkItemStore));
   //Iterate Through Projects
   foreach (Project tfs_project in wis.Projects)
   {
   treeView2.Nodes.Add(tfs_project.Name);
   }
6. To Access the Workitems in the Projects:
   
   private void treeView2_NodeMouseDoubleClick(object sender, TreeNodeMouseClickEventArgs e)
   {
   string tfs_projectName = e.Node.Text.Trim(); //The project name
   
   //Perform WIQL Query
   WorkItemCollection wic = wis.Query(
   " SELECT [System.Id], [System.WorkItemType]," +
   " [System.State], [System.AssignedTo], [System.Title] " +
   " FROM WorkItems " +
   " WHERE [System.TeamProject] = '" + tfs_projectName +
   "' ORDER BY [System.WorkItemType], [System.Id]");
   
   
   foreach (WorkItem wi in wic)
   {
   TreeNode newnode = new TreeNode();
   newnode.Text = wi.Id + wi.Title + "-" + wi.Description;
   newnode.Tag = wi;
   treeView1.Nodes.Add(newnode);
   //treeView1.Nodes.Add(wi.Title + "[" + wi.Type.Name + "]" + wi.Description );
   }

Issues: While connecting from home I found that it takes really long, or sometimes times out during performing the following:
wis = (WorkItemStore)tfs.GetService(typeof(WorkItemStore))

The solution that I found in the net was :
Go to Internet Exploreer> Connections> LAN Settings
Instead of having a "Detect Proxy Automatically", put in a definite "Proxy setting"

Show a context menu when right clicking on a treeview

private void tvwMenu_MouseUp(object sender, MouseEventArgs e)
{
//Select Node When Right Clicked & Set Context Menu To Use
if( e.Button == MouseButtons.Right )
{
TreeNode node = tvwMenu.GetNodeAt( new Point( e.X, e.Y ) );
if( node != null )
{
TreeNodeMenuTag tag = (TreeNodeMenuTag)node.Tag;
tvwMenu.SelectedNode = node;
tvwMenu.ContextMenuStrip = (tag.isMenu) ? cmnuMenuNode :
cmnuProgramNode;
}
}
}

Enum Functions

1. Iterating through an Enum:
   
   foreach (enmResponseInterval value in Enum.GetValues(typeof(enmResponseInterval)))
   {
   cmbXXX.Items.Add(value.ToString());
   }
   
2. Conditional Switch Statement with Enumeration String Value
   public enum Product
   {
   Word,
   Outlook,
   Excel
   }
   
   public void Process(string productName)
   {
   switch ((Product)Enum.Parse(typeof(Product), productName.ToString()))
   {
   case Product.Excel:
   // Do something
   break;
   case Product.Outlook:
   // Do Something
   break;
   case Product.Word:
   // Do something
   break;
   }
   }
