The final point I want to address about debugging startup code is that the SCM will add entries to the event log explaining why it can't start a particular service In the Event Viewer, look in the Source column for "Service Control Manager" If you also use the event log for your lightweight tracing, between the SCM entries and your tracing, you should be able to solve many of your startup problems If you use the event log, make sure your service dependencies are set so that your service will be started after the event log service Common Debugging Question: Why does every developer need Process Explorer I've already mentioned that Mark Russinovich's wonderful Process Explorer program makes it trivial to find which instance of DLLHOSTEXE has a particular DLL loaded and to determine whether you have relocated DLLs in a process.

Then, someone somewhere must have said, "Hey, let's try to package this stuff up and sell it to smaller ISPs and telephone companies" Thus, ISBU was formed Many engineers from MSN moved to join ISBU and a number of smaller companies were acquired to build up what would become Site Server, Commerce Server, and Microsoft Commercial Internet Server (MCIS) Instead of a Product Unit Manager (PUM) or a General Manager (GM) acting as the engineering manager in charge of each product team, we had a small handful of Business Unit Managers That's how all of us engineers in ISBU ended up working for a bunch of BUMs Microsoft invests in internal incubation projects such as our IPTV, Auto PC, and robotics projects as well as all the work done by Microsoft Research (http://researchmicrosoftcom).

However, there's so much more to Process Explorer such as being an outstanding debugging tool and I want to take a moment to discuss some of its excellent features By default, Process Explorer updates periodically, just like Task Manager Although this updating is great for general monitoring, it can make you miss some details when debugging It's best to set Process Explorer to manual updating by selecting the View menu, and then setting Update Speed to Paused Probably the best way to show you the power of Process Explorer is to run through a little demonstration You might want to follow along so that you can see the tool in action The first step is to start Process Explorer followed by NOTEPADEXE because I'll use it for the demonstration Set Process Explorer to manual updating by selecting the View menu, and then setting Update Speed to Paused.

When to Marshal by Value So how do you know when MBV is a good option Let's say that MBV is a compelling option when the following conditions are true: The object is not particularly large and complex. You're going to make intensive use of the object. You have no special security concerns. The object has no dependencies on remote resources such as files, databases, devices, or system resources. Some rather illustrious .NET Framework classes that support remoting through the MBV technique are the DataSet and DataTable classes. MBV Objects The .NET Remoting system serializes all the internal data of MBV objects and passes the stream to the calling AppDomain, as illustrated in Figure 12-2.

The first trick you can perform with Process Explorer is determining which DLLs are coming into your address space because of a particular operation In Process Explorer, press F5 to 523.

We also invest in projects that can help spur change in the software industry as a whole In April 2007, with more than 10 partners we launched the Microsoft Software as a Service (SaaS) Incubation Center Program In Microsoft, there are many models for incubations Established products often incubate features in the larger organization For example, the Office 12 ribbon, a new feature that changed the Office user interface, and the Windows Vista shuffle feature were incubations The code coverage tools that ship in the latest versions of Visual Studio were based on concepts developed first as internal tools projects in Microsoft Research and Windows Another approach we've used to incubate innovations is using an internal venture capital team Any employee can submit an idea, and the venture capital team will examine the feasibility of the idea using a process much like an industry venture capital firm would use.

Figure 12-2: How .NET Remoting marshals objects by value. After the data is in the client AppDomain, a new local object is instantiated and initialized and starts handling calls. To write remotable objects that are exchanged by value, you need to make them serializable, either by declaring the SerializableAttribute attribute or by implementing ISerializable. Aside from this, nothing else is required for instances of the class to be passed by value across AppDomains. Marshaling Objects by Reference When an object is marshaled by reference, the client process receives a reference to the server-side object, rather than a copy. This means that any call directed to the object is always resolved on the server within the native context of the object. The remoting infrastructure governs the call, collecting all information about the call and sending it to the server process. On the server, the correct object is located and asked to execute the call using the client's arguments. When the call is finished, the results are packaged and sent back to the client. Unlike MBV, MBR uses the network only for transmitting arguments and return values. Figure 12-3 shows the architecture of MBR remoting. 429

refresh the display, select the instance of NOTEPAD.EXE you started up a moment ago, and then press Ctrl+D to change the view to show the DLLs for Notepad. Activate Notepad and select Open from Notepad's File menu. Leave the Open dialog box open in Notepad and switch back to Process Explorer. Press F5 to refresh Process Explorer's display and you'll see a bunch of lines appear in green in NOTEPAD.EXE's DLL view, as shown in Figure 14-2. The green indicates which DLLs came into the address space since the last refresh. Of course, you can also see which DLLs leave the address space by switching back to Notepad and closing the Open dialog box, returning to Process Explorer, and refreshing the display with F5. All DLLs that have left the address space are shown in red. This ability to quickly see what's coming into and out of your processes is very helpful in determining what's causing module loads and unloads. An added benefit is that the color highlighting showing what's been loaded and unloaded also applies to the EXE listing in the upper half of the Process Explorer display.

Just like in industry, very few ideas get funding through this mechanism The Bill Gates ThinkWeek is another source of ideas that can become incubations Microsoft employees can submit white papers detailing new ideas and innovations, and during ThinkWeek, which occurs approximately twice each year, Bill reads and comments on scores of papers At the end of the week, Bill's notes, once hand-written, are shared with the company In 2005, the Wall Street Journal described ThinkWeeks in this way: It's a twice-yearly ritual that can influence the future of Microsoft and the tech industry A Think Week thought can give the green light to a new technology that millions of people will use or send Microsoft into new markets One week in 1995 inspired Mr Gates's paper, "The Internet Tidal Wave," that led Microsoft to develop its Internet browser and crush Netscape.

Figure 14-2: DLL view for Process Explorer showing new DLLs added to the Notepad process Process Explorer's second trick lets you peek at all sorts of excellent information about a process simply by double-clicking it. The dialog box that pops up shows you four or five tabs depending on the process. The first tab, Image, shows you information such as the path and current directory for the process, as well as offers a button to let you kill the process. The second tab, Performance, shows you the important performance data information related to the CPU, memory, I/O, and GDI handles. The third tab, Security, shows you the security information such as groups for the process and granted access. If the process is a Microsoft Win32 service or host, the Services tab shows you the name of the particular services running in that process. The final tab, Environment, lists the environment variables active for that process. In using the Security and Environment tabs, I've tracked down some very interesting problems related to security programming because Process Explorer is about the only tool that makes this information easy to see.

Figure 12-3: How NET Remoting marshals objects by reference The NET Remoting implementation of MBR provides for a proxy/stub pair and a physical channel for network transportation The proxy represents the remote object to the client, as it simply mirrors the same set of methods and properties Each client invocation of a remote method actually hits the local proxy, which, in turn, takes care of routing the call down to the server A method invocation originates a message that travels on top of a channel and a transmission protocol Each message passes through a chain of hook objects (called sinks) on each side of the transport channel Sinks are nearly identical to Windows hooks By defining and registering a sink, the programmer can perform a specific operation at a specific stage of the remoting process.
