Figure 19-17. Nonclustered index B-tree structure Nonclustered indexes are associated with the RID lookup and key lookup operations. RID lookups are bookmark lookups into the heap using row identifiers (RIDs), while key lookups are bookmark lookups on tables with clustered indexes. Once SQL Server locates the index rows that fulfill a query, if the query requires more columns than the nonclustered index covers, then the query engine must use the row locator to find the rows in the clustered index or the heap to retrieve necessary data. These are the operations referred to as a RID and key lookups, and they are costly operations so costly, in fact, that many performance-tuning operations are based on eliminating them.

As you have just seen, when you reference a COM server using the Visual Studio 2005 Add Reference dialog box, the IDE responds by generating a brand-new .NET assembly taking an Interop. prefix (such as Interop.SimpleComServer.dll). Just like an assembly that you would create yourself, interop assemblies contain type metadata, an assembly manifest, and under some circumstances may contain CIL code. As well, just like a normal assembly, interop assemblies can be deployed privately (e.g., within the directory of the client assembly) or assigned a strong name to be deployed to the GAC. Interop assemblies are little more than containers to hold .NET metadata descriptions of the original COM types. In many cases, interop assemblies do not contain CIL instructions to implement their methods, as the real work is taking place in the COM server itself. The only time an interop assembly contains executable CIL instructions is if the COM server contains COM objects that have the ability to fire events to the client. In this case, the CIL code within the interop assembly is used by the CLR to manage the event handing logic. At first glance, it may seem that interop assemblies are not entirely useful, given that they do not contain any implementation logic. However, the metadata descriptions within an interop assembly are extremely important, as it will be consumed by the CLR at runtime to build a runtime proxy (termed the Runtime Callable Wrapper, or simply RCW) that forms a bridge between the .NET application and the COM object it is communicating with. You ll examine the details of the RCW in the next several sections; however, for the time being, open up the Interop.SimpleComServer.dll assembly using ildasm.exe, as you see in Figure 17-5.

Provided you take all these steps, your JavaScript code will be able to call your Silverlight method through the <object> element that represents the Silverlight content region. However, to make this task easier, it s important to give the <object> element a unique ID. By default, Visual Studio creates a test page that assigns a name to the <div> element that contains the <object> element (silverlightControlHost), but it doesn t give a name to the <object> element inside. Before continuing, you should create a test page that adds this detail, as shown here: <div id="silverlightControlHost"> <object data="data:application/x-silverlight," type="application/x-silverlight-2-b1" width="400" height="300" id="silverlightControl"> ... </object> <iframe style="visibility:hidden;height:0;width:0;border:0px"></iframe> </div>

As you can see, although the original VB6 project only defined a single COM class (ComCalc), the interop assembly contains three types. To make things even more confusing, if you were to examine the interop assembly using Visual Studio 2005, you only see a single type named ComCalc. Rest assured that ComCalcClass and _ComCalc are within the interop assembly. To view them, you simply need to elect to view hidden types with the VS 2005 Object Browser (see Figure 17-6).
