Integration Testing vs. Test Flags and Emulation As mentioned earlier, services no longer stand alone; they are usually built on platform services and need those services in place to be fully functional. With all these dependencies, the integration points of services must be tested in a manner that allows each service or layer of a service to maintain its own ability to innovate independently. Integration testing and test flags and emulation are techniques to help with this challenge. The selection of the right technique is driven by the degree to which the services are coupled, as shown in Figure 14-7. vb.net print pdf to specific printer: Best 20 NuGet printing Packages - NuGet Must Haves Package vb.net read pdf file NET PDF Text Extractor & Converter - Extract Text from PDF C#/ VB ...

NET Tutorial 16 : Loading a PDF ( Adobe Acrobat) File in a VB. Extensions for C++ code for an assembly Anakrino was written by Jay Freeman and is downloadable from http://wwwsaurikcom/net/exemplar/ Unlike NET Reflector, Anakrino has source code available Although Anakrino isn't perfect, it's a fantastic way to learn about how the NET Framework code all fits together Using Anakrino is self-explanatory, so I won't bother to go into it One caveat I will mention is that the source code is quite "original" with a huge amount of template usage, so you'll need to make a serious commitment if you want to extend it A few commercial decompilers that produce better output have been released at the time of this writing, but they're prohibitively expensive, so Anakrino's foibles are perfectly acceptable Summary Although managed code is terrific because we no longer have to mess with memory corruptions and leaks, we still have to know how to use the debugging features. vb.net read pdf file itextsharp How to Read PDF document in Vb . net ????? - MSDN - Microsoft

9 May 2014 ... This article will explain how we can read a PDF file in ASP. ... here I will show you to read PDF file using iTextSharp both in C# and VB . NET . The following code demonstrates a fully qualified XPath location: descendant::invoice[@year = 2002] The XPath processor first selects all the descendants of the context node Next it selects from this set all the <invoice> nodes whose year attribute equals 2002 Tip You can use the wildcard character (*) to indicate all the nodes in a given axis For example, the expression child::* denotes all the children of the current context node Likewise, descendant-or-self::* means all the descendants and the node itself.. In this chapter, I concentrated on the unique issues associated with Visual Studio NET and debugging managed applications I started by discussing the issues particular to advanced breakpoints It's absolutely wonderful that Visual Studio NET can call methods and properties from conditional breakpoints, but it means you must be extra careful to avoid causing side effects in your breakpoints Also remember that if you mess up the condition, the debugger won't stop if it can't properly evaluate the condition The exciting Watch window offers all sorts of extra power for managed applications With its full expression evaluator, you can easily call methods and properties so that you can influence debugging behavior to help your testing efforts Additionally, for C# and Managed Extensions for C++ applications, you can add your custom types to the autoexpand rules to make debugging even faster. By using test flags and emulation, you can test a service without any platform services. To really make the one box or test cluster work for rapid testing and regression of internal bugs, a service needs to have the ability to remove the dependency on these platform services. Test flags and emulation do this in different ways. Finally, although you might never program in MSIL, it's simple to learn and can help you truly see what the NET Framework class library is doing behind the scenes If you'd like more information about MSIL, make sure to check out Partition III CILDOC, which you can find in <Visual Studio NET installation directory>\SDK\v11\Tools Developers Guide\docs In that information, you'll find the lowdown on every instruction and what each does.. Location Steps A location path is composed of several child elements called location steps. Each location step is actually a location path and, as such, can be expressed in an abbreviated or fully qualified form, as appropriate. Location steps are separated by forward slashes, as shown in Figure 6-2. Overview Although managed development does a great job of protecting you from all sorts of potential problems, native code development gives you every opportunity not only to shoot yourself in the foot, but also to wound the person in the next cubicle over Doing native development is more work, but on the positive side, you get the ultimate in control and speed Additionally, even though some marketing folks might make it sound like you need to drop everything and shift to NET, such an immediate changeover isn't going to happen any time soon In this chapter, I'll cover the advanced techniques Microsoft Visual Studio NET gives you for debugging your native applications I'll start with discussing breakpoints, because with native code, you have even more options for stopping a process We'll move on to more details about the Watch window as well as remote debugging. Test flags internally stub out calls to a platform service A global setting in a configuration file or the Windows registry turns the test flags on or off When the test flag is set to true, any calls to a platform service follow a new code path designed to allow the test to complete The test flag code path usually returns a positive response with simple static well-formed data Some test code is written to return errors and variable data, but this is less common Test flags are a great way for a tester to quickly take a new build and regress simple bugs such as changes to an error message string or UI navigation, essentially bugs that have nothing to do with integration Test flags can also be used during stress tests. Figure 6-2: A location path consists of one or more location steps, each of which can be expressed in full or abbreviated form. Consider the following three-step expression: invoices/descendant::invoice[@year = 2002]/child::country[text() = 'USA'] The first step selects all the nodes named <invoices> below the context node. This node-set is then passed as the context node-set to the next location step. The second location step is expressed in an unabbreviated form and loops through all the descendants of each previously selected <invoices> node. When processed, each node plays the role of the context node and provides different position information. At the end of the second step, the node-set contains only the <invoice> nodes that have a parent <invoices> and a year attribute set to 2002. The final step further narrows the node-set by excluding all the nodes that have no <country> child whose text equals USA. Note The at sign (@) that you use to indicate a node attribute is actually an abbreviation for another particular axis type: the attribute. The full syntax for the year attribute is attribute::year. The XPath specification recommends a number of abbreviations that are commonly used in coding, including the following shortcuts: Use a period (.) to indicate the context node and two periods (..) to refer to the parent. When no axis is specified, child:: is assumed. Finally, [n] means the nth node in the current context node-set; this array-like notation is equivalent to [position() = n]. Finally, I'll cover Intel IA32 (Pentium) assembly language so that you can always figure out what happened, even when you have no source code around and are left in the bowels of third-party or operating system code Advanced Breakpoints for Native Applications 5 introduced the common breakpoints between native and managed applications In this chapter, I'll turn to the unique issues related to native applications and some of the problems you'll run into Additionally, I'll discuss the magical data breakpoints offered for native applications Advanced Breakpoint Syntax Unlike managed debugging, native debugging has additional capabilities to control exactly when and where breakpoints occur Because of the nature of native symbol generation, many times you need to provide the debugger with additional help so that it properly places the breakpoint where you want it When it comes to debugging symbols, the rules are much looser than the strict C++ scoping rules. For example, it's perfectly reasonable to have multiple top-level symbols for LoadLibrary Each module that imports LoadLibrary has a symbol for it (to indicate importing) and the module that exports it has a symbol as well (to indicate exporting) The advanced breakpoint syntax helps set the scope to the exact symbol you mean What's interesting about the advanced breakpoint syntax is that you used to see it all the time in Microsoft Visual C++ 6 and prior versions because that's how the old Breakpoint dialog box displayed the breakpoints you set In Visual Studio NET, you no longer see any advanced breakpoint syntax displayed, but you still need to know what that syntax is to truly control the debugger The advanced breakpoint syntax is composed of two parts The first part is the context portion, and the second part is the location, expression, or variable. vb.net pdfreader class vb . net form fill | Adobe Community - Adobe Forums
