Figure 4-14: The code can be used to change the value of the forecolor attribute from blue to black. Adding and Deleting Nodes A source XML document can also be easily read and modified by adding or deleting nodes. Let's look at a couple of examples. To add a new node, you simply read until the parent is found and then write an extra set of nodes to the XML writer. Because there might be other nodes with the same name as the parent, use a Boolean guard to ensure that the insertion takes place only once. The following code demonstrates how to proceed: void AddUser(string name, string pswd, string role) { XmlTextReadWriter rw; rw = new XmlTextReadWriter(inputFile, outputFile); rw.WriteStartDocument(); // Modify the root tag manually rw.Writer.WriteStartElement(rw.Reader.LocalName); // Loop through the document bool mustAddNode = true; // Only once while(rw.Read()) { switch(rw.NodeType) { case XmlNodeType.Element: rw.Writer.WriteStartElement(rw.Reader.LocalName); if ("Users" == rw.Reader.LocalName && mustAddNode) 158 vb.net read pdf file itextsharp: How to read and extract data from pdf file in vb | The ASP.

Figure 5-3: Child breakpoints in the Breakpoints window What you're looking at in Figure 5-3 are child breakpoints. Basically, the Visual Studio .NET documentation says that they exist and that's it. For example, the documentation says child breakpoints occur when you set breakpoints on overloaded functions, but the Breakpoints window always shows them as top-level breakpoints. You can see child breakpoints when you're debugging multiple executables and both programs load the same control into their AppDomain/address spaces, and you set breakpoints in the same spot in that control in both programs. What's wild is that the Breakpoints window in Figure 5-3 is showing you a single program that's currently running in which I set a breakpoint on Console.WriteLine. If you right-click on a child breakpoint while debugging and select Go To Disassembly, the Disassembly window displays the disassembly code. However, you'll get a clue as to what's happening if you right-click on a child breakpoint, select Properties from the shortcut menu, and in the resulting Breakpoint dialog box, click on the Address tab, shown in Figure 5-4. You'll see that the debugger reports that the breakpoint is set on System.Console.WriteLine at the very start of the function. 199 vb.net print pdf file silently: VS 2012 [RESOLVED] printing form to pdf-VBForums visual basic read pdf iTextSharp - Dave's Notebook

Security testing has become an integral part of Microsoft's culture in recent years. Reactions to malicious software and spyware have given all engineers at Microsoft a security mindset. Security testing is such a major subject that it is more worthy of an entire book than a section of this single chapter. In fact, a quick browse on an online bookstore shows me no less than half a dozen books on security testing, including books written by Microsoft employees such as Hunting Security Bugs by Gallagher, Landauer, and Jeffries, as well two security books in the How to Break series by James Whittaker (who is also a noted software security expert). Additionally, Writing Secure Code by Howard and LeBlanc is on many testers' bookshelves at Microsoft. Any of these books or others on the subject will be beneficial if you desire depth or breadth in this area. The tester's role in security testing is not just to find the bugs, but to determine whether and how the bug can be exploited. A few of the key approaches and techniques for security testing are discussed in the following subsections. vb.net itextsharp pdfreader How to convert PDF Byte Array into PDF document? - Laserfiche Answers

Hi, I need to read and parse a PDF file that has 50,000 pages. The "Save As" option within the Acrobat Reader is not of much use. The PDF file ... Figure 5-4: Breakpoint on any call to ConsoleWriteLine If that's not clear enough, you can always execute your program and notice that you stop deep down in the x86 assembly language soup If you pull up the Call Stack window, you'll see that you're stopped inside a call to ConsoleWriteLine and you'll even see the parameter(s) passed The beauty of this undocumented means of handling a breakpoint is that you'll always be able to get your applications stopped at a known point of execution Although I made only a single call to ConsoleWriteLine in my program, the Breakpoints window shows 19 child breakpoints, as shown in Figure 5-3 Based on some trial and error, I discovered that the child breakpoints count is related to the number of overloaded methods In other words, setting breakpoints by typing in the . { mustAddNode = false; rw.Writer.WriteStartElement("User"); rw.Writer.WriteAttributeString("name", name); rw.Writer.WriteAttributeString("password", pswd); rw.Writer.WriteAttributeString("role", role); rw.Writer.WriteEndElement(); } else rw.Writer.WriteAttributes(rw.Reader, false); if (rw.Reader.IsEmptyElement) rw.Writer.WriteEndElement(); break; } } // Close the root tag rw.Writer.WriteEndElement(); // Close the document and any internal resources rw.WriteEndDocument(); } NET Framework class and method name, or typing where you don't have source code, will set a breakpoint on all overloaded methods In case you check the documentation and see that ConsoleWriteLine only has 18 overloaded methods, let me tell you that if you look at the SystemConsole class with ILDASM, you'll see that there are really 19 overloaded methods The ability to stop on a method that's called anywhere in my AppDomain is amazingly cool I've learned quite a bit about how the NET Framework class library fits together by choosing to stop at specific NET Framework class library methods Although I've been using a static method as an example, this technique works perfectly well on instance methods as well as properties as long as those methods or properties are called in your AppDomain. To delete a node, you simply ignore it while reading the document. For example, the following code removes a <User> node in which the name attribute matches a specified string: while(rw.Read()) { switch(rw.NodeType) { case XmlNodeType.Element: if ("User" == rw.Reader.LocalName) { // Skip if name matches string userName = rw.Reader.GetAttribute("name"); if (userName == name) break; } // Write in the output file if no match has been found 159 Threat modeling is a structured activity that reviews application architecture to identify potential security threats and vulnerabilities. Threat modeling is in wide use at Microsoft, and testers are highly active participants in the threat model process. The familiarity testers typically have with input validation, data handling, and session management drives them toward being key contributors when examining applications for potential security issues. Threat models as do many other concepts discussed in this chapter work best when carried out during program design. A threat model is a specification just like a functional specification or design document. The big difference is that the intention of a threat model is to identify all possible ways that an application can be attacked, and then to prioritize the attacks based on probability and potential harm. Good threat modeling requires skills in analysis and investigation two skills that make Test a well-suited participant in the process. More information about threat modeling, including examples, can be found in Threat Modeling by Frank Swiderski and Window Snyder (Microsoft Press, 2004). Keep in mind that to set breakpoints on a property, you'll need to prefix the property with get_ or set_, depending on what you want to break on For example, to set a breakpoint on the ConsoleIn property, you'd specify Consoleget_In Also, the language selected in the Breakpoint dialog box is still important When setting these AppDomain-wide breakpoints in places where you don't have source code, I like to use Basic so that if I mess up the case, the breakpoint is still set 200. There are two issues you need to be aware of when setting these AppDomain-wide breakpoints. The first is that breakpoints set this way aren't saved across executions. Consider the example in which we added a breakpoint while debugging on Console.WriteLine. The Breakpoints window will show "Console.WriteLine" when you re-execute the program, but the breakpoint changes to a question mark glyph and the breakpoint changes to unresolved and will never be set. Second, you can set these AppDomain-wide breakpoints only when the instruction pointer is sitting in code in which you have a PDB file. If you try to set the breakpoint in the Disassembly window with no source code available, the breakpoint will be set only as unresolved and never activated. Although you might think I've beaten the topic of setting quick location breakpoints to death, there's still one completely non-obvious but extremely powerful place to set location breakpoints. Figure 5-5 shows the Find combo box on the toolbar. If you type the name of the class and method you want to break on in that combo box and press F9, a breakpoint on that method is set if that method exists. If you specify an overloaded method, the system will automatically set breakpoints on all the overloaded methods. The Find combo box is a little more discriminating in that if it can't set the breakpoint, it won't. Additionally, like the Breakpoint dialog box, if you're working on a C++ project, specifying the class name in the Find combo box and pressing F9 will set a breakpoint on each method in that class. rw.Writer.WriteStartElement(rw.Reader.LocalName); rw.Writer.WriteAttributes(rw.Reader, false); if (rw.Reader.IsEmptyElement) rw.Writer.WriteEndElement(); break; } } Fuzz testing is a technique used to determine how a program reacts to invalid input data A simple approach would be to use a hex editor to change the file format of a data file used by a program for example, modifying the bits in a doc file used by Microsoft Word In practice, the process is nearly always much more methodical Rather than randomly changing data, fuzz tests usually involve manipulating the data in a manner that exposes a potential security issue such as an exploitable buffer overrun Fuzz testing is equally applicable to database testing, protocol testing, or any other situation where part of a system or application must read and interpret data Finding Fuzzing Holes During Windows Vista development, I oversaw the file fuzzing tests on the Microsoft Windows Shell (user interface). vb.net pdf reader control VB .
