Listing 9-2. Creating and Starting a Thread public class Program { public static void Main() { Thread myThread = new Thread(MyThreadMethod); myThread.Start(); //main thread continues here } private static void MyThreadMethod() { //do some work here } } It is possible to wait for completion or termination of another thread before moving on with the application, which is done by calling the Join method of the thread you want to wait for. There are three overloads of this method (see Listing 9-1): the parameterless version blocks and waits infinitely for the termination. The other two variants expect a timeout parameter indicating the maximum waiting time.

Look back at Figures 10-6 and 10-7 to see the visual appearance of the pages. Both Default.aspx and ProjectEdit.aspx are content pages, adding their content to that already provided by MasterPage.master: <%@ Master Language="C#" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head id="Head1" runat="server"> <title>Untitled Page</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> </head> <body> <form id="form1" runat="server"> <div id="mainTable"> <div id="header"> <asp:Label ID="PageTitle" runat="server"> </asp:Label> </div> <div id="navigation"> <div id="navigationContent"> <asp:TreeView ID="TreeView1" runat="server" DataSourceID="SiteMapDataSource1" ShowExpandCollapse="False" SkipLinkText="" > <NodeStyle CssClass="nav" /> </asp:TreeView> </div> </div> <div id="subnavigation"> <div id="logout"> <asp:LoginStatus ID="LoginStatus1" runat="server" OnLoggingOut="LoginStatus1_LoggingOut" /> </div> </div> <div id="content"> <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server"> </asp:ContentPlaceHolder> </div> </div> <asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="False" /> </form> </body> </html> MasterPage.master defines the header/title bar at the top of the page. The area immediately beneath the header/title bar contains the Login button, and there is a navigation area down the left. Perhaps most importantly, it also defines a content area containing a ContentPlaceHolder control: <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server"> </asp:ContentPlaceHolder> This is the area where content pages provide their content, and it is the main body of the page. You ll see how each content page provides content for this area later in the chapter.
