As is the case when symbols aren't loaded, the ANSI and Unicode conditions still apply If symbols are loaded, the breakpoint syntax for breaking on LoadLibrary is {,,KERNEL32DLL}_LoadLibraryA@4 or {,,KERNEL32DLL}_LoadLibraryW@4 After you've figured out the advanced breakpoint syntax for setting the breakpoint, bring up the New Breakpoint dialog box by pressing Ctrl+B On the Function tab/Function edit control, enter the appropriate advanced breakpoint syntax After clicking OK, you'll get the usual warning about IntelliSense not finding the breakpoint Click OK so that the debugger will set the breakpoint Look in the Breakpoints window and you'll see that a full red dot is next to the breakpoint and the Name column lists the breakpoint in full syntax glory You can also right-click the breakpoint and select Go To Disassembly from the context menu to see where the exported function resides in memory. vb.net read pdf into byte array: Use VB .

The use of logs and simplified logic in the emulators allows them to scale much higher than trying to test against a test instance of a platform service Emulators can also simulate varying latency no matter what the true load is Testing Against Production To operations engineers and many product teams, the thought of allowing another service to test its new code against your live site seems ridiculous Who would want all those mean testers doing horrible things to the code and trying to break your service The thought of letting testers bang away at production sends chills down the spine of most operations managers Over the years, I have developed a few arguments to help everyone realize that testing against production is a good thing and to explain that it is happening whether you like it or not. vb.net print pdf to specific printer: Free .

Conditional Expressions Although managed code allows you to call methods and properties from conditional expression breakpoint modifiers, native code doesn't Additionally, conditional expressions can't evaluate C++ macro values, so if you want to compare a value against TRUE, you'd have to use 1 instead (though true and false are evaluated correctly evaluated) With C++ code, as with the particular languages in managed code, any conditional expressions must use the C++ values Even with these small limitations, location breakpoint conditional expression modifiers are extremely powerful because in addition to the ability to evaluate variables values, you have access to a special set of values named pseudoregisters For the most part, pseudoregisters are register values that appear on the CPU Visual Studio NET greatly improved the register types you can use and display. read pdf file line by line using vb.net Embed PDF into a VB .

As we'll see in the section "Compiling Expressions," on page 274, only compiled XPath expressions support namespace information In particular, they get namespace information through an instance of the XmlNamespaceManager class The SelectSingleNode Internal Implementation The SelectSingleNode method is really a special case of SelectNodes Unfortunately, there is no performance advantage in using SelectSingleNode in lieu of SelectNodes The following pseudocode illustrates the current implementation of the SelectSingleNode method: public XmlNode SelectSingleNode(string xpathExpr) { XmlNodeList nodes = SelectNodes(xpathExpr); return nodes[0]; } The SelectSingleNode method internally calls SelectNodes and retrieves all the nodes that match a given XPath expression Next it simply returns the first selected node to 209. In addition to the regular CPU registers, Visual Studio now supports advanced registers such as MMX, SSE, SSE2, and 3DNow! Some examples of pseudoregisters are shown in Table 7-1 Notice that actual CPU registers have the @ delimiter and that the two special values start with $ You can find the complete list of register values by consulting the CPU documentation for both Intel and AMD (Advanced Micro Devices) Remember that in Visual C++ 6, you could also specify @ in front of pseudoregisters For backward compatibility, you can still do the same with Visual Studio NET 2003, but future versions will support only $ on pseudoregisters, so you should get used to setting it now Additionally, to view the value, some of you are used to entering the register values without the @ in front of the register name However, I'll always show registers with the @ prefix 241. The first example I use is to ask anyone to go out and try to create a WLID account starting with the term test or test account You will have to try a lot of combinations of letters and numbers after these words to find an available name Something tells me that the individuals who created these accounts are doing some sort of testing and that there is very little WLID can do to stop them All services run some level of transaction monitoring as a way to alert the SOC when something goes wrong After every upgrade, the operations engineers often run a battery of tests called smoke tests to ensure that all major functionality is still working Well, these are tests just like the ones run against a one box and other test environments This means that operations is testing in production already. the caller. Using SelectSingleNode perhaps results in a more easily readable code, but doing so certainly does not improve the performance of the application when you need just one node. In the next section, we'll build a sample Microsoft Windows Forms application to start practicing with XPath expressions, thus turning into concrete programming calls all that theory about the XPath query language. The Sample XPath Evaluator The sample XPath Evaluator application is a Windows Forms application that loads an XML document and then performs an XPath query on it. The application's user interface lets you type in both the context node and the query string. Next it creates an XML DOM for the document and calls SelectNodes. The output of the expression is rendered as an XML string rooted in an arbitrary <results> node, as shown here: <results> ... XML nodes that match ... </results> The sample application is shown in Figure 6-3. You can find the code listing for this application in this book's sample files. Table 7-1: Example Pseudoregisters Pseudoregister @EAX @BL @MM0 @XMM1 $ERR $TIB Description The return value register (32-bit value) Low word of EBX register (16-bit value) MMX register 0 Streaming SIMD Extensions (SSE) register 1 Last error value (special value) Thread information block (special value) The last two values in Table 7-1 offer extra power with conditional breakpoints With $ERR, you can look at the thread's last error value (the value returned by calling the GetLastError API), so you'd stop only when that last error condition was met For example, if you wanted to stop only when the last error value returned by an API function was ERROR_INSUFFICIENT_BUFFER, indicating a data buffer was too small, you'd first look up ERROR_INSUFFICIENT_BUFFER in WINERRORH and see the value is 122 Your breakpoint conditional expression would be $ERR==122 The $TIB special pseudoregister opens up a solution to a vexing problem in Visual Studio NET Unfortunately, there's no built-in way to explicitly set a location breakpoint that fires only in a specific thread (As you'll see in the next chapter, WinDBG does have this capability built in). Hackers are constantly looking for vulnerabilities in production services If a service must be robust enough to withstand a hacker's attempt to break in, it should be able to survive a few automated tests Mashups is the last example I use Many mashups are developed by small teams of developers and use public APIs Some even go so far as to screen scrape to build their application The point is that they must develop their mashup over the Internet against production In this case, they are not only testing their solution against production, they are developing against production Note Screen scraping is a technique for taking a fully rendered UI for a mashup this is a Web page ignoring the binary information such as pictures, and pulling out and parsing the data from it. Figure 6-3: The XPath Evaluator sample application in action. Initializing the Application When the user clicks the Load button, a StreamReader object is used to load the specified XML document and refresh the left text box, which displays the contents of the XPath source document. I used the I/O API to read the document to preserve the newline characters. An alternative approach consists of loading the document into the XmlDocument class and then getting the source through the document element's OuterXml property. In this case, however, what you get is a string of contiguous characters that does not display well in a fixed-width text box. When working on big server applications such as ISAPI filters, it's very common to have a few methods that are called by lots of threads, but you don't want to wear out your index finger pressing GO a million times because the debugger stops at each occurrence in each thread The first step to getting around this problem is to be stopped in the debugger and bring up the Threads window so that you can see all the thread IDs Determine which thread you want to stop in and remember the thread ID The second step is to set a location breakpoint on the common routine and bring up the New Breakpoint dialog box by right-clicking on the breakpoint and selecting Properties Click the Condition button and type in the following expression: *(long*)($TIB+0x24) == <thread id> The thread ID is at offset 0x24 in the thread information block. vb.net itextsharp pdfreader How to extract text from a PDF file in C#, VB .
