XmlAttributes changesFirstName = new XmlAttributes(); XmlAttributeAttribute newFirstName = new XmlAttributeAttribute(); newFirstName.AttributeName = "firstname"; changesFirstName.XmlAttribute = newFirstName; over.Add(typeof(Employee), "FirstName", changesFirstName); You need a distinct XmlAttributes object for each element you want to override. The XmlAttributes object collects all the overrides you want to enter for a given element. In this case, after creating a new XmlAttributeAttribute object, we change the attribute name and store the resultant object in the XmlAttribute property of the overrides container. When the overrides are for a specific element, you use a particular overload of the XmlAttributeOverrides class's Add method. In this case, you specify a third argument the name of the element being overridden. The following code replaces the current settings of the FirstName property: over.Add(typeof(Employee), "FirstName", changesFirstName); The code is slightly different if you need to override an element instead of an attribute, as shown here: XmlAttributes changesFirstName = new XmlAttributes(); XmlElementAttribute newFirstName = new XmlElementAttribute(); newFirstName.ElementName = "firstname"; changesFirstName.XmlElements.Add(newFirstName); over.Add(typeof(Employee), "FirstName", changesFirstName); A different attribute class is involved XmlElementAttribute with a slightly different programming interface. Similar code should be written for each class property you want to map to a source XML attribute or element. Caution If the name of the XML root does not match the name of the target class, the deserializer can't proceed further, and the CanDeserialize method returns false. If the root and class names match, the deserialization can take place. Any unmatched attributes and elements are treated as unknown objects, and the proper deserialization event is fired. read pdf file using itextsharp vb.net: how to read PDF file using vb .

The first parameter to the GetFirstStackTraceString and GetNextStackTraceString functions is a flag option parameter that lets you control the amount of information that you want to see in the resultant string. The following string shows all the options turned on: 001B:004017FD (0x00000001 0x00000000 0x00894D00 0x00000000) CrashHandlerTest.exe, wmain()+1407 d:\dev\booktwo\disk\bugslayerutil\tes ts\crashhandler\crashhandler.cpp, line 0226+0007 byte(s) The values in parentheses are the first four possible parameters to the function. Table 13-1 lists the options and what each will include in the output string. Some of you might wonder why I didn't include local variables as one of the output options. There were two main reasons. The first is that the main use of my CrashHandler code is intended to be at customer sites. Unless you like giving away your proprietary secrets, you're probably not distributing PDB files with private information to your customers. The second reason is that local variables, especially when you want them expanded, take up quite a bit of memory. I felt I was already pushing the limits with the static buffers I was using and that adding more to cover local variables would be prohibitive. byte(s), The first CFD demonstrates how control flow would simply bypass the case statements and return an empty string if the operating system's major version number is not equal to an integer value of 5. If the operating system environment is Windows Server 2003, control flow jumps from the switch statement Mixing Overrides and Events Up to now, we have considered a simple scenario in which a direct mapping exists between elements in the source XML and properties in the target class. In this case, all of your overrides end up changing the structure of the XML code being deserialized. But what if you need to apply some logic in the middle of your code Let's consider a scenario in which the XML source contains a birthdate field but your class contains an Age property instead. In this case, an attribute override is no longer useful and hooking the deserialization process is the only way. Earlier in this chapter, we discussed deserialization events. If the birthdate value is expressed as an attribute, you write an UnknownAttribute handler; otherwise, resort to an UnknownElement event handler. The following code snippet shows how to determine the correct value for the Age property based on birthdate: 414 The first four possible parameters The module name The symbol name of the stack address The source file and line number information of the stack address at A3 to A6 and also returns an empty string as illustrated in the second CFD. The third CFD shows the control flow from A3 to the case statement at A4 when the operating system environment is Windows 2000 Server and returns the string Win2K. And, if the operating system environment is Windows XP, the fourth CFD demonstrates how the control flow jumps around A6 to the A7 case statement and returns the string WinXp. Another place where block testing is important is in exception handling. Interestingly enough, behavioral testing typically does not exercise many of the exception handlers in a program, so designing structural tests to reduce risk and ensure exceptions are handled correctly is important. If the application handles exceptions and an exception occurs during the execution of the application's code, the system will search for the appropriate exception handler and control flow will transfer to that exception handler. ConvertToPositiveInteger Function To show you the GetFirstStackTraceString and GetNextStackTraceString functions in action, I included two sample test programs with the sample files for this book. The first, BugslayerUtil\Tests\CrashHandler, exercises the CrashHandler methods. The second program, CrashTest, shows a full dialog box example you could display in the event of an unhandled crash. Between these two programs, you should get a pretty good idea of how to use all the functions I've presented. Figure 13-2 shows CrashTest displaying its crash dialog box. // Unknown attribute detected if (e.Attr.Name == "birthdate") { Employee emp = (Employee) e.ObjectBeingDeserialized; DateTime dt = DateTime.Parse(e.Attr.Value); emp.Age = (int) (DateTime.Now.Year - dt.Year); } Populating Collection Properties An even more complex scenario arises when the source XML contains embedded data, the result of INNER JOIN operations being rendered in XML. Consider the following statement: SELECT firstname, lastname, title, hiredate, birthdate, terr.territorydescription FROM Employees As employees INNER JOIN EmployeeTerritories AS empterr ON employees.employeeid=empterr.employeeid INNER JOIN Territories AS terr ON empterr.territoryid=terr.territoryid WHERE employees.employeeid=@empID FOR XML AUTO The XML output for the empID parameter that equals 1 is shown here: <employees firstname="Nancy" lastname="Davolio" ...> <terr territorydescription="Wilton" /> <terr territorydescription="Neward" /> </employees> This output changes a little bit if you use the ELEMENTS clause, as follows: <employees> <firstname>Nancy</firstname> <lastname>Davolio</lastname> ... <terr> <territorydescription>Wilton</territorydescription> <territorydescription>Neward</territorydescription> </terr> </employees> The application is always notified of any <terr> elements through an UnknownElement event. Suppose you also want any territory description to populate a StringCollection property in the Employee class. The following code shows how to handle the event and accumulate the data for an unknown element in the string collection: if (e.Element.Name == "terr") 415 Figure 13-2: CrashTest dialog box Minidumps Some of you might be wondering why I went to the trouble to write and continue to support the EXCEPTION_POINTERS manipulation code in the CrashHandler library because you've heard about or used a thing called minidumps The main reason is that there are many companies out there using my code in their applications and I didn't want to break compatibility However, the minidump capabilities are so amazingly cool, I'm sure that many folks will rip out the existing code inside their crash handlers and simply replace it with a call to the minidump-creation functions as soon as they can I've already talked about how to read minidump files with both Microsoft Visual Studio NET and WinDBG in 7 and 8, respectively What I want to turn to now is how you can create your own minidumps right from your own code. A0 private static int ConvertToPositiveInteger(string s) { try { return (int)Convert.ToUInt32(s); } catch(FormatException) { return -1; } catch(OverflowException) { return -1; } } After the symbol server technology and Visual Studio NET itself, I think that minidumps API is the second greatest thing Microsoft has released for native developers in the last couple of years! However, there are a few quirks with creating your own, so I want to show you how to get the very best minidumps possible so that you can solve your bugs much faster The MiniDumpWriteDump API DBGHELPDLL contains the MiniDumpWriteDump function, which does all the work DBGHELPDLL version 51 or later contains the function This means that the versions that come with stock Microsoft Windows 2000 (up through Service Pack 3) are earlier versions and don't export MiniDumpWriteDump Additionally, versions of DBGHELPDLL earlier than version 60 had a bug in MiniDumpWriteDump that caused a deadlock when you called it to write a minidump from the current process. vb.net read pdf file text How to Extract Text from PDF Document in C#, VB .
