In the App_Code folder, I created a class called Utility and added the properties in Listing 1-10. Listing 1-10. Utility Methods public static bool IsUserAuthenticated { get { return HttpContext.Current.User.Identity.IsAuthenticated; } } public static Guid UserID { get { if (IsUserAuthenticated) { return (Guid)Membership.GetUser().ProviderUserKey; } else { Guid userId = new Guid(HttpContext.Current.Request.AnonymousID.Substring(0, 36)); return userId; } } }fcdd Whenever I needed the unique identifier for the current user, I would access it with Utility.UserID. But then I had to handle the transition from anonymous to authenticated. To do so, I added a method to Global.asax called Profile_OnMigrateAnonymous, shown in Listing 1-11. Listing 1-11. Profile_OnMigrateAnonymous public void Profile_OnMigrateAnonymous(object sender, ProfileMigrateEventArgs args) { Guid anonID = new Guid(args.AnonymousID); Guid authId = (Guid)Membership.GetUser().ProviderUserKey;

new Expression[] { nullExp, methodExp, arrayExp, targetExp })); } ParameterExpression returnValue = Expression .Parameter(originalExpression.Type); calls.Add(Expression.Assign(returnValue, originalExpression)); afterCalls.Reverse(); calls.AddRange(afterCalls); calls.Add(returnValue); var advisedObject = new DynamicMetaObject( Expression.Block( new[] { returnValue }, calls.ToArray() ), originalObject.Restrictions ); return advisedObject; }

// migrate anonymous user resources to the authenticated user // remove the anonymous user. Membership.DeleteUser(args.AnonymousID, true); } In the case of the basket, I just added the items that were in the anonymous user s basket into the authenticated user s basket, and removed the anonymous account and all associated data. I have considered adding a Guid property to the Profile properties called UserID, but the dynamic compiler for the ASP .NET runtime works only in code-behind files. It would not work in the Utility class held in the App_Code directory, which is where I place a good deal of the code. So the preceding technique was the only option.

First, notice that, unlike line 4 in Listing 7-8, the code in Listing 7-12 no longer calls the constructor of an advice class Instead, it calls the GetInterceptors method of AdvisorChainFactory in line 69 to get a list of advice objects based on pointcut matches With this change, our example no longer hard-codes the advice objects it applies to dynamic objects The WeaveAspect method is still the workhorse here It s more complex than earlier because it now needs to prepare the proper expressions that satisfy the method signatures of IDynamicAdvice s BeforeInvoke and AfterInvoke It also needs to handle not just one advice object but a list of them Lines 16 to 23 shows the code that prepares the expressions that represent the input parameters needed for calling BeforeInvoke and AfterInvoke Lines 30 to 43 iterate through the advice objects returned by GetInterceptors.

When you work on a website with Visual Studio, you are able to use the Website Administration tool to create users and roles. But this utility is not a feature built into Microsoft Internet Information Server (IIS). To work with users and roles, you have to do it yourself either in the database by carefully calling stored procedures or by creating an interface to safely use the Membership API. I chose to create a couple of user controls that I can easily drop into any website. The two main controls, UserManager.ascx and RolesManager.ascx, do the work to manage the users and roles. These controls are held in another user control called MembersControl.ascx. This control switches between three views to create a new user, edit existing users, and edit roles. Listings 1-12 through 1-17 provide the full source for these controls. Listing 1-12. UserManager.ascx <%@ Control Language="C#" AutoEventWireup="true" CodeFile="UserManager.ascx.cs" Inherits="MemberControls_UserManager" %> <asp:Label ID="TitleLabel" runat="server" Text="User Manager"></asp:Label><br /> <asp:MultiView ID="UsersMultiView" runat="server" ActiveViewIndex="0"> <asp:View ID="SelectUserView" runat="server" OnActivate="SelectUserView_Activate"> <table> <tr> <td> <asp:GridView ID="UsersGridView" runat="server" AllowPaging="True" AutoGenerateColumns="False" OnInit="UsersGridView_Init" OnPageIndexChanging="UsersGridView_PageIndexChanging" OnRowCommand="UsersGridView_RowCommand"

For each advice object, the code creates a method call expression that represents a call to the advice object s BeforeInvoke method and a method call expression that represents a call to the advice object s AfterInvoke method The expressions created in lines 20 to 23 are passed to the ExpressionCall method to create the method call expressions After the method call expressions are created, we need to put them into a block expression like we did in Listing 7-8 The block expression that holds all the method call expressions is referenced by the calls variable in Listing 7-12 In Listing 7-8, there is only one advice object and therefore only one call expression for calling BeforeInvoke and only one call expression for calling AfterInvoke Here we have a list of ordered advice objects.
