Figure 12-3. Three threads in a process and their associated access tokens Figure 12-3 shows an example of a threaded process and the access tokens assigned at the process and thread level. Notice that the process is running under the security context in Token X. You can see from the diagram that the process has three threads running inside it, and that the process created Thread A and Thread B in the default manner by copying Token X to the individual threads. Thread C, however, runs under the security context of Token Z, giving it different permissions than Threads A and B. Whenever a process launches another process, the calling process copies its access token to the new process. This ensures that the newly created process runs under the same security context of the parent process. Like threads, the parent process has the capability to authenticate an account and create a new access token for the new process. You should rarely be creating an entirely new process from an ASP.NET application, but if you do, understand that it runs using the same security context of the process or thread from which it was launched.

In building this sample, we immediately saw the value that the ASP.NET AJAX extensions provide in terms of quickly adding AJAX-style functionality to an existing web page. To take the AJAX example to the next level, we added an UpdateProgress server control to provide a visual cue to the end user that work is occurring. This is a very important design requirement in building effective AJAX-enabled web applications. Listings 2-21 and 2-22 contain the HtmlControlsAJAX demonstration .aspx and code-behind class files, respectively. Listing 2-21. The HtmlControlsAJAX Web Form .aspx File <%@ Page Language="C#" MasterPageFile="~/MasterPage/ControlsBook2MasterPage.Master" AutoEventWireup="true" CodeBehind="HtmlControlsAJAX.aspx.cs" Inherits="ControlsBook2Web.Ch02.HtmlControlsAJAX" Title="HTML Controls Demo" %> <asp:Content ID="Content1" ContentPlaceHolderID="NumAndTitle" runat="server"> <asp:Label ID="NumberLabel" runat="server" Width="14px">2</asp:Label>  <asp:Label ID="TitleLabel" runat="server" Width="360px"> Encapsulating Functionality in ASP.NET</asp:Label> </asp:Content>

Figure 15-9. A new master page The ContentPlaceHolder doesn t have any remarkable properties. Here s an example that creates a master page with a static banner followed by a ContentPlaceHolder and then a footer (shown in Figure 15-10): <%@ Master Language="C#" AutoEventWireup="true" CodeFile="SiteTemplate.master.cs" Inherits="SiteTemplate_master" %> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Untitled Page</title> </head> <body> <form id="form1" runat="server"> <table width="100%"> <tr> <td bgcolor="black" style="..."> <img align="left" src="headerleft.jpg" /> <img align="right" src="headerright.jpg" /> <br />My Site<br /> </td> </tr> </table> <br /> <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server"> </asp:ContentPlaceHolder> <br /> <em>Copyright 2005.</em> </form> </body> </html>

Figure 15-10. A master page at design time Master pages can t be requested directly. To use a master page, you need to build a linked content page.

Tip Executing processes from an ASP.NET application is usually indicative of bad design. Process execution is not very scalable, so think about redesigning the application to avoid calling external processes.

To use your master page in another web page, you need to add the MasterPageFile attribute to the Page directive. This attribute indicates the filename of the master you want to use: <%@ Page Language="C#" MasterPageFile="~/SiteTemplate.master" ... %> Notice that the MasterPageFile attribute begins with the path ~/ to specify the root website folder. If you just specify the filename, ASP.NET checks a predetermined subfolder (named MasterPages) for your master page. If you haven t created this folder or your master page isn t there, it checks the root of your web folder next. Setting the MasterPageFile attribute isn t enough to transform an ordinary page into a content page. The problem is that content pages have a single responsibility to define the content that will be inserted in one or more ContentPlaceHolder controls (and to write any code you need for these controls). A content page doesn t define the page, because the outer shell is already provided by the master page. As a result, attempting to include elements such as <html>, <head>, and <body> will fail, because they re already defined in the master page. To provide content for a ContentPlaceHolder, you use another specialized control, called Content. The ContentPlaceHolder control and the Content control have a one-to-one relationship. For each ContentPlaceHolder in the master page, the content page supplies a matching Content control (unless you don t want to supply any content at all for that region). ASP.NET links the Content control to the appropriate ContentPlaceHolder by matching the ID of the ContentPlaceHolder with the Content.ContentPlaceHolderID property of the corresponding Content control. If you create a Content control that references a nonexistent ContentPlaceHolder, you ll receive an error.
