My first challenge was figuring out where I should grab the registers and what value I should use for the exception address I finally decided that the best thing to do would be to use the exact registers as they came into my SnapCurrentProcessMiniDump function because they were the users' registers at the time they called my function To cleanly get registers coming into a function, I had to get a crack at the registers before the compilergenerated code whacked them, so I used the naked calling convention What I ended up doing was utilizing a CONTEXT structure on the stack and writing the inline assembly language to copy the registers into the appropriate structure fields I caused the first bug myself because I copied the 16-bit segment registers into their CONTEXT member fields and didn't realize that the structure still utilized 32-bit values for those members.

Both share an architectural design that includes layers for request/response handling, object serialization, and data transportation Both share underlying network protocols such as Simple Object Access Protocol (SOAP) and HTTP Overall, Web services and NET Remoting are two distinct and independent sides of the same coin Web services a clearly XML-based technology are a special case of the NET Remoting infrastructure The NET Framework infrastructure for remoting can be seen as an abstract approach to interprocess communication Web services and NET Remoting are technologies that represent concrete implementations of that abstract interface As distinct implementations, they end up using different building blocks to set up constituent features such as object serialization, type description, and reflection The actual underlying technologies that make Web services and NET Remoting happen are chosen according to the final goal of each technology Web services are targeted to cross-platform communication and heterogeneous systems .

Consequently, I left garbage in the upper world Copying the segment registers in the EAX register and using that value to fill the structure worked just fine The only real work necessary was to get the EBP and ESP values because I had to use those to build my local variables, but getting them was no big deal For ESP and EBP, I copied the values as they were at the time SnapCurrentProcessMiniDump was called The SNAPPROLOG macro in Listing 13-5 shows the prolog, and SNAPEPILOG handles the epilog code necessary for naked calling convention functions The one CONTEXT register value not filled out is the EIP register, which takes a little more work.

My initial thought was that the general registers I captured would be enough, but I was unsure whether the debuggers needed other values, such as the floating point values or extended registers, to properly display the user's information Therefore, I thought it was safe enough to call GetThreadContext on the executing thread to get these other values Since my code didn't touch any of those registers, I was going to get the actual values at the time of the call Of course, I made the call with a second CONTEXT structure so that I wouldn't overwrite my carefully saved values Once I had the registers retrieved by GetThreadContext, I copied the specific values I saved at the beginning of the function over the retrieved values At this point I had the register state correct when the call to SnapCurrentProcessMiniDump occurred.

NET Remoting doesn't allow for cross-platform communication, but it is highly optimized for NET-to-NET communication In a nutshell, NET Remoting takes in the best aspects of its Microsoft Win32 predecessor Distributed Component Object Model (DCOM) and elegantly fills in the gaps In this chapter and 13, we'll examine the major features of each technology and demonstrate that a common, platform-independent piece of code say, a NET Framework class can be exposed in both models and perform in the same way in NET Framework as well as Win32 and Linux applications NET Remoting as a Better DCOM Prior to the advent of the NET Framework, DCOM was the underlying technology of choice for any sort of remote communication between Microsoft Windows applications Based on a proprietary binary protocol, DCOM has suffered since its conception from a number of shortcomings.

My original thought was to put the return address onto the stack as the EIP register as well as the exception address Accessing the return address is now easy because Microsoft documented the _ReturnAddress intrinsic function _ReturnAddress will give you the address anywhere in the function To use _ReturnAddress, you'll need to add the following two lines to your code so that the compiler doesn't complain the function is undefined I like to put these lines in my precompiled header file so that they are globally accessible extern "C" void * _ReturnAddress ( void ) ; #pragma intrinsic ( _ReturnAddress ) Because I had the rest of the registers set as they were before the call, very few people would have noticed the difference if I had simply used the return address as the EIP and exception address.

When a conditional clause contains two or more Boolean subexpressions, we can use the structural testing technique condition testing. Condition testing is similar to decision testing, but tests for condition testing are designed to evaluate the true and false outcomes for each subexpression in a compound conditional clause. Condition testing provides better sensitivity to control flow as compared to decision testing when testing compound conditional clauses. For example, the Next Date program that we tested in 5 contains the IsInvalidGregorianCalendarDate function that checks to verify the input variables are not within the

Given that I can be quite anal-retentive, I went ahead and looked a few bytes back from the return address for the 0xE8 and 0xFF opcodes, which are the near CALL instruction and the far CALL instruction, respectively That way the register set is completely aligned and appears at the instance of the call You can see the work of determining the appropriate CALL type in CalculateBeginningOfCallInstruction The rest of the work after getting the register squared away is simply setting up the MINIDUMP_EXCEPTION_INFORMATION structure, opening the file handle, and calling MiniDumpWriteDump You can see all this in action in the CommonSnapCurrentProcessMiniDump function in Listing 13-5 514.

For this reason, DCOM never charmed its way into the average programmer's heart, although it did prove to be functional and effective DCOM is somewhat quirky to set up and configure, and under certain, but relatively frequent, circumstances, it also raises serious interoperability exceptions that basically put you in the unenviable position of having to change the connectivity engine for the sake of the application or simply give up 423.

Opening up a file created with SnapCurrentProcessMiniDump is just like opening any other minidump. The only difference is that the debugger will report the exception number as zero and show the instruction pointer on the CALL instruction itself. Now you have no excuse for not snapping minidumps all the time. Set up a background thread that waits on an event, and when that even is signaled from an external program, call SnapCurrentProcessMiniDump in your thread to get perfect dumps all along the execution of your program.

date ranges identified by the i18 Invalid equivalence class subset in Table 5-1. The IsInvalidGregorianCalendarDate function uses a compound conditional clause to determine whether the three input variables that are passed to the month, day, and year parameters are valid (meaning the variables are not within the specified date ranges) or invalid (meaning the variables are within the specified date ranges). Decision testing of the IsInvalidGregorianCalendarDate function requires only two tests to evaluate the conditional clause to both the true and false outcomes. But it should be obvious that simple decision testing is inadequate to test the structure and control flow of this function effectively. IsInvalidGregorianCalendarDate() Function

Prior to the advent of the .NET Framework, we were used to writing XML-driven Microsoft Windows applications based on the MSXML COM-based library. Unlike classes in the .NET Framework, however, MSXML is a bolted-on API that communicates with the rest of the application but does not really integrate with it. Communication entails the activity or the process of passing information to others. It is based on some set of signals that both parties understand and that encode the information being exchanged. Integration, on the other hand, means that items are combined so that they are closely linked and form one unit. This distinction is significant. The MSXML library can be imported into your code but remains an external, selfcontained black box that acts as a server component. .NET Framework applications, on the other hand, use XML classes along with other classes in the .NET Framework, resulting in a homogeneous combination of "equal-sized" pieces. As a self-contained component, the MSXML must provide itself with advanced features such as asynchronous parsing. This feature is apparently lacking in the XML classes of the .NET Framework. By integrating XML classes with other classes in the .NET Framework, however, you can easily obtain the same functionality and even gain more control over the overall process.

Summary This chapter covered crash handlers, which are exception handlers and unhandled exception filters Crash handlers allow you to get more information about a crash and provide a better face to the user when your application does have problems The key to debugging faster is also getting the information you need when confronted with a problem, and crash handlers allow you to do that C++ exceptions and SEH exceptions are sometimes confused The C++ language specification provides C++ exceptions, whereas the operating system provides SEH; the two kinds of exception handling are completely different, though intertwined in the dirty implementation details I hope I was able to show you the ugly truth about the love affair with C++ exception handling and make you think twice about using it in your application With the overhead associated with C++ exception handling, you'll take a performance hit However, the fact that catch (...
