Figure 4-3: WDBG in action Overall, I'm happy with WDBG because it's an excellent sample, and I'm proud that WDBG shows all the internals techniques that a debugger uses. Looking at the WDBG user interface (UI), however, you can see that I didn't spend a great deal of time fiddling with the UI portions. In fact, all the multiple-document interface (MDI) windows in WDBG are edit controls. That was intentional I kept the UI simple because I didn't want UI details to distract you from the essential debugger code. I wrote the WDBG UI using the Microsoft Foundation Class (MFC) library, so if you're so inclined, you shouldn't have any trouble designing a spiffier UI. Before moving into the specifics of debugging, let's take a closer look at WDBG. Table 4-2 lists all the main subsystems of WDBG and describes what they do. One of my intentions in creating WDBG was to define a neutral interface between the UI and the debug loop. With a neutral interface, if I wanted to make WDBG.EXE support remote debugging over a network, I'd just have to replace the local debugging DLLs. vb.net pdfreader class: How to read pdf line by line and fetch the data in c# - C# Corner vb.net adobe pdf reader component Manipulating PDF files with iTextSharp and VB .

On small projects, log files often are the reports. Log files report pass or fail results for tests and suites of tests, and as long as there aren't too many log files to look at, this can be sufficient reporting. Many test projects at Microsoft, for example, include thousands of test suites and hundreds of thousands of tests. For projects of this size, manually examining log files is out of the question. One possible option is for tests to log results directly to a database, but the overhead of connecting to a database isn't feasible for all test scenarios. Network connectivity might not be available for all scenarios, and network connectivity to a database is much slower than is logging on directly to a local storage device or debug stream. A common and effective solution is to automate the parsing of log files. A log file parser can execute outside the scope of running the test case and works equally well for single log files as for batches of log files. The parser can simply record the test case name and the test result, or it can record other potentially essential metadata such as the type of test, component under test, and information needed to debug a failure. A database typically stores the parsed data, and applications or Web pages display the results. Table 10-5 shows a partial list of test case results.

Table 4-2: WDBG Main Subsystems Subsystem WDBG.EXE Description This module contains all the UI code. Additionally, all the breakpoint processing is taken care of here. Most of this debugger's work occurs in WDBGPROJDOC.CPP. 173 Table 4-2: WDBG Main Subsystems Subsystem LOCALDEBUG.DLL Description This module contains the debug loop. Because I wanted to be able to reuse this debug loop, the user code, WDBG.EXE in this case, passes a C++ class derived from CDebugBaseUser (defined in DEBUGINTERFACE.H) to the debug loop. The debug loop will call into that class when any of the debugging events occurs. The user's class is responsible for all synchronization. For WDBG.EXE, WDBGUSER.H and WDBGUSER.CPP contain the WDBG.EXE uses simple coordinating class. SendMessage synchronization. In other words, the debug thread sends a message to the UI thread and blocks until the UI thread returns. If the debugging event is one that required user input, the debug thread blocks after the send message on a synchronization event. Once the UI thread processes the Go command, it sets the synchronization event and the debug thread starts running again. This simple module is just a wrapper around the API functions for manipulating the debuggee's memory and registers. By using the interface defined in this module, WDBG.EXE and I386CPUHELP.DLL can instantly handle remote debugging just by replacing this module. This module is the IA32 (Pentium) helper module. Although this module is specific to Pentium processors, its interface, CPUHELP.H, is CPU-independent. If you defined in wanted to port WDBG to a different processor, this module is the only one you should have to replace. The disassembler in this module came from the Dr. Watson sample code that used to ship in the Platform SDK. Although the disassembler works, it appears to need updating to support the later Pentium CPU variants. In addition, the XmlConvert class also lets you encode and decode XML names so that they comply with the W3C standards The encoding process escapes any invalid characters into entities consisting of the character's numeric representation in the current encoding set.. Component Passed Failed Skipped Blocked Not run Total results %Passed %Complete component 3 872 18 32 4 0 926 97.53 100.00 Reading and Writing Memory Reading from a debuggee's memory is simple. ReadProcessMemory takes care of it for you. A debugger has full access to the debuggee if the debugger started it because the handle to the process returned by the CREATE_PROCESS_DEBUG_EVENT debug event has PROCESS_VM_READ and PROCESS_VM_WRITE access. If your debugger attaches to the process with DebugActiveProcess, you must have SeDebugPrivileges for the process you're attaching to get read and write access. Before I can talk about writing to the debuggee's memory, I need to briefly explain an important concept: copy-on-write. When Windows loads an executable file, Windows shares as many mapped memory pages of that binary as possible with the different processes using it. If one of those processes is running under a debugger and one of those pages has a breakpoint written to it, the breakpoint obviously can't be present in all the processes sharing that page. As soon as any process running outside the debugger executed that code, it would crash with a breakpoint exception. To avoid that situation, the operating system sees that the page changed for a particular process and makes a copy of that page that is private to the process that had the breakpoint written to it. Thus, as soon as a process writes to a page, the operating system copies the page. 174 Formatting Text The XmlTextWriter class allows you to specify a few properties to configure the way in which newline characters, quotation marks, and indentation are defined. Normally, XML documents use tab characters or blanks to indent child nodes, although an XML document rendered as an endless string is by all means a perfectly valid XML document. As mentioned, the properties involved with XML formatting are Formatting, IndentChar, Indentation, and QuoteChar. The first three are somewhat correlated, whereas the latter simply indicates the character to be used to enclose attributes by default, the double quotation mark. Formatting lets you control the formatting style by toggling it on and off altogether. When Formatting is set to Formatting.Indented (the other possible value is Formatting.None), the XML writer attributes a special role to IndentChar and Indentation that would otherwise be ignored. Indentation specifies the number of characters to indent for each level in the document's hierarchy. Conversely, IndentChar 128 Writing to the debuggee memory is almost as straightforward as reading from it Because the memory pages you want to write to might be marked as read-only, however, you first need to call VirtualQueryEx to get the current page protections Once you have the protections, you can use the VirtualProtectEx API function to set the page to PAGE_EXECUTE_READWRITE so that you can write to it and Windows is prepared to do the copy-on-write After you do the memory write, you'll need to set the page protection back to what it originally was If you don't, the debuggee might accidentally write to the page and succeed when it should fail If the original page protections were read-only, the debuggee's accidental write would lead to an access violation. Note that skipped tests do not affect the pass rate, but blocked test cases are part of the calculation. Pass rates in this example are calculated as Passed / (Total Results - Skipped). Using the definitions in Table 10-4, tests marked as skipped are done so purposely and reflect tests that are intentionally not run. Blocked test cases represent unknown areas. Even though the test has not run, because it is unknown whether it will pass or fail, it is included in the fail rate. There are various alternate calculations for determining pass rates, but the preceding method is the one used most prevalently at Microsoft. vb.net read pdf into byte array How to read pdf line by line and fetch the data in c# - C# Corner
