Table 11-2: Methods of the XmlSerializer Class Method Description Indicates whether the contents pointed to by the specified CanDeserialize XmlReader object can be successfully deserialized using this instance of the serializer class. Deserialize Deserializes an XML document read from a stream, text, FromTypes or an XML reader. Static method that returns an array of XmlSerializer objects created from an array of types. Useful for speeding operations when you need to create multiple serializers for different types. Serializes an object into an XML document. itextsharp read pdf line by line vb.net: Extract Data From PDF File -VBForums vb.net extract text from pdf How to read and extract data from pdf file in vb | The ASP.

Tags: pdf pdfbox ikvm. net vb parsing. problems When I asked what was going to happen if we didn't get it fixed before I had to leave Seattle, his response was, "We'll be following you to New Hampshire" This bug had already moved into the super-serious category The next evening I showed up at the apartment the engineers had rented and was confronted with two people who were so tired they were wobbling on their feet They'd been working on this bug for nearly three weeks straight without much of a break After showing me their application, I immediately broke out in a complete and utter flop sweat! They were working on a custom GINA (Graphical Identification and Authentication), the logon screen that used a custom smart card reader to log all across a custom terminal server session! Talk about a nasty application to debug! Since much of the application ran inside LSASS. Figure 5-8: The initial pair-wise test matrix reveals tests with mutually exclusive variable combinations. As with the Deserialize method, the output for the Serialize method can be a stream, text, or an XML writer.

"… EXE, you could get debugging started, but if you clicked anywhere outside the debugger, you locked the machine To make my life even more interesting, the engineers used the Standard Template Library (STL) all over the place, so in addition to a very tough debugging problem, they had unreadable code As we all should know, STL's main claim to fame isn't reusable data structures but rather job security Since STL code is unreadable and unmaintainable, your company will be forced to keep paying you because only you can understand the code I asked them whether they could show me anything resembling duplicable crashes or data corruption They had a document listing the 10 or 12 places they had seen crashes My initial hypothesis was that they had a wild write to uninitialized memory. After spending a few hours figuring out how the system fit together and getting used to debugging their application, I started trying to determine whether we could find those uninitialized pointers Grinding through the source code, I noticed they had lots of catch (..) statements all over the place At the end of the first evening, I told them they needed to remove all the catch (..) statements so that we could see the corruption immediately and try to start narrowing down the problem The Outcome When I went back to the apartment the second day, these engineers were pushed right to the edge of their physical limits They told me that once they'd commented out the catch (..) statements, the application didn't initialize While the developers took a nap, I started looking through the startup code and quickly found the following: //catch ( ... What About Negative Testing In this example, you create a model file for positive tests, meaning the expected output of each combination should not result in an error state When the OK button is clicked in the dialog box, the imaginary text editor changes the font, style, effect, color, and size of the selected glyphs accordingly, and you can verify the correct results either visually if you are manually testing or programmatically through the GetFont application programming interface (API) as an oracle for automated tests But what about negative testing, where you expect an error state or condition The PICT tool also includes the ability to define invalid variable states in a model file When testing with invalid variable states, each test should have only one invalid parameter value to avoid input masking. Table 11-3: Events of the XmlSerializer Class Event Description UnknownAttribute Fires when the deserializer encounters an XML attribute of unknown type. UnknownElement Fires when the deserializer encounters an XML element of unknown type. Fires when the deserializer encounters any XML UnknownNode node, including Attribute and Element. Fires when the deserializer encounters a recognized UnreferencedObject type that is not used. Occurs during the deserialization of a SOAP-encoded XML stream. (More on this topic in the section "Deserializing XML Data to Objects," on page 496.) ) //{ return ( FALSE ) ; //} In their sleep-addled state, they'd forgotten to comment out the return statement I commented it out, recompiled, and ran the program It crashed almost immediately On the second run, it crashed in the same place, which was the first time they'd seen a consistent crash The third crash was a charm, and I started inspecting every single thing happening up the stack After carefully reading the code, we found the error in only a couple of hours The documentation called for a buffer that was passed to another function to be 250 characters in size A developer was passing a local variable as the buffer and had typed 25 instead of 250 Once we fixed the typo, we were able to run the application to completion! The Lesson. Input masking occurs when a program throws an error condition on the first invalid variable and subsequent values are not tested When designing tests (especially automated tests), I prefer to separate the model used for positive testing and the model used for negative testing to simplify the test code and to reduce the possibility of false negatives by keeping the appropriate oracle focused on the specific purpose of the test You know that font styles are directly dependent on certain font types For example, the Brush Script font can have a font style of only italic or bold and italic So, as you can see in Figure 5-8, rows 5, 12, and 16 would result in a false negative Also, the Monotype Corsive font can be regular, or bold and italic only. The lesson is simple: don't use catch (...)! This particular company had already wasted weeks of work (and tons of money) attempting to track down a bug that was completely solvable but not reproducible because catch (...) was involved. UnknownNode is a more generic event that fires for all nodes. It reaches the client application before more specific events such as UnknownAttribute and UnknownElement arrive. Serializing Objects to XML The[Serializable] attribute, which makes a class serializable through formatters, is not inheritable and must be explicitly assigned to derived classes. No such explicit conditions exclude some classes from the benefits of the XML serialization technique. This certainly does not mean that all the classes can be serialized to XML, however. 396 Don't Use _set_se_translator In the first edition of this book, I covered the use of an interesting API named _set_se_translator It has the magical ability to turn your SEH errors into C++ exceptions by calling a translation function that you define, which simply calls throw on the type you want to use for the conversion I might as well confess now that although I was well intentioned, my advice was wrong When you use _set_se_translator, you quickly find out that it doesn't work in release builds The first problem with _set_se_translator is that it isn't global in scope; it works only on a per-thread basis That means you probably have to redesign your code to ensure that you call _set_se_translator at the beginning of each thread Unfortunately, doing that isn't always easy. The rows 4 and 15 in Figure 5-8 violate these dependency rules and would also result in a false negative for these tests It is not uncommon to encounter features that rely on mutually exclusive variable states between parameters to restrict or constrain certain events or actions that are mutually exclusive It would be foolish to try to manually change these values in the output because you might not be aware of which other parameter variable states were used in determining the n-wise combinations To overcome this problem PICT includes the ability to define conditional and invariant constraints of specific variable states using a basic if-then syntax in the model file. vb.net pdf read text VB .
