You'll derive your particular profiler callback class from CBaseProfilerCallback and override the particular methods you're interested in receiving notifications for. That way you can concentrate on the important parts that you need, not the rest of the methods that will just get in the way. After you've named your derived class, you'll need to implement a function, AllocateProfilerCallback, with the following prototype. In that function, allocate your CBaseProfilerCallback-derived class and return it. The rest of the code in ProfilerLib.h will take care of everything else. ICorProfilerCallback * AllocateProfilerCallback ( ) ; Finally, you'll need to take the EXAMPLE.DEF file out of ProfilerLib, copy it to your project, rename it, and replace the LIBRARY statement in it to properly do all the exports necessary to make a COM DLL. In addition to taking care of all the COM goo for you, ProfilerLib also adds additional methods to CBaseProfilerCallback that will make your life easier. Some of them I've already mentioned in this chapter, but there are others. Whenever I run across anything 415 dwReason , )

The DiffGram format of the WriteXml method can provide a stateful representation of the DataSet contents, as opposed to the stateless nature of the normal form Because of its ability to preserve the state of the constituent rows, the DiffGram format is also used to remote a DataSet object through both the Microsoft NET Framework remoting architecture and Web services But let's start by taking a closer look at the structure of a DiffGram script..

that I think I might want to reuse, I add it to ProfilerLib, so make sure you check out the project files to see what other time-saving routines are already written for you. As you'd expect by now from my code, there's a sample program, DoNothing, in the Tests directory under the ProfilerLib directory. It's the simplest profiler you can make and shows you exactly how to use ProfilerLib. It does process all notifications, but it simply beeps when initializing and unloading. That's my patented "Debug-by-Ear" method of development. Additionally, all the other utilities I wrote that utilize the Profiling API use ProfilerLib as their base classes, so you can see more advanced usage. ProfilerLib has saved me a ton of time, and I hope it will save you a great deal of time as well. ExceptionMon Once I had ProfilerLib up and running, I was able to start ExceptionMon. Looking at the ICorProfilerCallback interface, you'll see that you have all sorts of amazing callbacks to let you know exactly what processing is happening when an exception occurs. It's almost like someone at Microsoft was reading my mind! At an initial glance, you might think that ExceptionMon was absolutely trivial to implement. As usual, reality was a little bit different. In my design for ExceptionMon, I wanted to record which exception was thrown, which finally handlers were called, and where the exception was handled. The exception handling notification methods in the ICorProfilerCallback interface, listed in the following code, fit the bill exactly. The fact that you also get the function IDs as well as the object ID of the exception thrown and caught is icing on the cake. STDMETHOD ( ExceptionThrown ) ( ObjectID thrownObjectId ) ; STDMETHOD functionId ) ; ( ExceptionUnwindFinallyEnter ) ( FunctionID

Figure 13-4: Windows Error Reporting dialog box. Most users of Windows see a similar dialog box each time an application crashes. Although I, for one, would like to see far fewer appearances of this dialog box, it has one advantage: Every time it appears, in the background it is generating data points that Microsoft uses to increase product quality. The dialog box shown in the figure is a part of the Windows Error Reporting (WER) infrastructure. Note that on the Windows Vista operating system, errors can be configured to be automatically sent to Microsoft without the need to interact with an error reporting dialog box.

A DiffGram is an XML serialization format that includes both the original values and the current values of each row in each table. In particular, a DiffGram contains the current instance of rows with the up-to-date values, plus a section where all the original values for changed rows are grouped. Each row is given a unique identifier that is used to track changes between the two sections of the DiffGram. This relationship looks a lot like a foreign key relationship. The following listing outlines the structure of a DiffGram:. <diffgr:diffgram xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1"> <DataSet> ... </DataSet> <diffgr:before> 361

STDMETHOD ( ExceptionCatcherEnter ) ( FunctionID functionId , ObjectID ; I quickly whipped up the initial ExceptionMon using ProfilerLib, writing the output to a logging file in the same directory the process ExceptionMon is loaded into. The first small issue I ran into was how to best debug ExceptionMon. Since the CLR does all the work to bring the specified profiler into the address space, I wanted to ensure I could start debugging right from the beginning. Since you already have to utilize environment variables to get the profiler started, I decided to go ahead and add one, EXPMONBREAK, which, if set, would cause ExceptionMon to call DebugBreak so that I could get a debugger attached. Although you can debug the profiler like you would with any native DLL loaded into a process, I prefer the DebugBreak call because the profiler will be loaded into Visual Studio .NET since it hosts the CLR. You can always limit the process loading by setting the EXPMONPROC environment variable to set just the single process to debug. However, for development and testing purposes, I like to run multiple programs to test. By using the EXPMONBREAK scheme, I can get multiple debuggers attached to multiple processes easily. Because I am mentioning environment variables, I need to talk about two that are primarily for handling ASPNET_WP.EXE/W3WP.EXE exception monitoring. By default, ExceptionMon doesn't flush the output file, so you need to stop ASPNET_WP.EXE/W3WP.EXE to see any reported exceptions. However, if you set the EXPMONFLUSH environment variable, all writes are flushed immediately. The other issue with file writing is that ExceptionMon will put the logging file into the same directory as the process, but that's a problem because the default ASPNET account 416 objectId )

probably doesn't have permission to create files in %SYSTEMROOT%\MicrosoftNET\Framework\%FRAMEWORKVERSION%, which is where ASPNET_WPEXE resides For Windows Server 2003, the account is NETWORK SERVICE and W3WPEXE resides in %SYSTEMROOT%\System32\inetsrv The EXPMONFILENAME environment variable is where you can specify the complete path and filename for the output file for ExceptionMon Obviously, you'll have to double-check that the ASPNET user account has create and write permission to the directory The initial version of ExceptionMon worked great because you were handed the function ID and object IDs and could simply call the appropriate methods in the ICorProfilerInfo interface to acquire the class and function tokens to look up names in the metadata The code in Listing 10-1, CBaseProfilerCallback::GetClassAndMethodFromFunctionId, shows all the work necessary to look up the class and method names from a function ID.

WER is a flexible event-based feedback infrastructure designed to gather information about the hardware and software problems with applications or the operating system that Windows can detect, report the information to Microsoft, and provide users with any available solutions. WER is a simple and secure method for users to provide information about application crashes and provides a database that categorizes and prioritizes reports for Microsoft and partner software vendors. It also provides a means for Microsoft and vendors to respond with status reports, requests for additional information, or links to other information about a specific issue. On Windows Vista, Problem Reports and Solutions in Control Panel, shown in Figure 13-5, keeps a record of all system and application issues reported through WER and gives you more information about the errors, including a list of all existing possible solutions for these problems.

... </diffgr:before> <diffgr:errors> .. </diffgr:errors> </diffgr:diffgram> The <diffgr:diffgram> root node can have up to three children The first is the DataSet object with its current contents, including newly added rows and modified rows but not deleted rows The actual name of this subtree depends on the DataSetName property of the source DataSet object If the DataSet object has no name, the subtree's root is NewDataSet The subtree rooted in the <diffgr:before> node contains enough information to restore the original state of all modified rows For example, it still contains any row that has been deleted as well as the original contents of any modified row All columns affected by any change are tracked in the <diffgr:before> subtree The last subtree is <diffgr:errors>, which contains information about any errors that have occurred in a particular row.

In-Process Debugging and ExceptionMon Once the basic version was up and running, I thought a useful feature would be to add a stack trace whenever an exception was thrown That way you could see how you got into the situation in the first place and could take a look at the conditions Looking at the documentation for the profiling API, I noticed you could pass a bit option to ICorProfilerInfo::SetEventMask COR_PRF_ENABLE_INPROC_DEBUGGING to turn on in-process debugging With in-process debugging, the profiling API gives you notifications of events, but you'll need some way of gathering more detailed information that you can get through the ICorProfilerInfo interface Since Microsoft has already developed a fine advanced debugging API that works hand-in-hand with the CLR, the idea was to give us a limited version of the debugging API, which can perform tasks like look up live variable values and walk the stack.
