Repetition testing Repetition testing is a simple, brute force technique of determining the effect of repeating a function or scenario The essence of this technique is to run a test in a loop until reaching a specified limit or threshold, or until an undesirable action occurs For example, a particular action might leak 20 bytes of memory This isn't enough to cause any problems elsewhere in the application, but if the test runs 2,000 times in a row, the leak grows to 40,000 bytes If the function provides core functionality that is called often, this test could catch a memory leak that might become noticeable only after the application has run for an extended period of time There are usually better ways to find memory leaks, but on occasion, this brute force method can be effective. vb.net read pdf file contents: [Solved] itextsharp read pdf file - CodeProject vb.net read pdf file itextsharp NET PDF Text Extractor & Converter - Extract Text from PDF C#/ VB ...

Is there anything to make it easier to understand I realize that people much smarter than I wrote the STL supplied with Visual Studio NET, but even so, it's nearly impossible to understand On one hand, the concept of STL is good because it has a consistent interface and is widely used On the other hand, the reality of the STL supplied with Visual Studio NET and with templates in general is that if you have any kind of problem, you have more difficulty figuring it out than you would debugging straight at the assembly-language level Better than the Visual Studio NET supplied STL is the free STL from STLport (wwwstlportorg) Not only is STLport infinitely more readable, but it also has much better support for multithreading and excellent debugging support built in. vb.net print pdf to default printer: VB .

Using iTextSharp's PdfReader class to extract the deflated content of every page, I use a simple function ExtractTextFromPDFBytes to extract the text contents ... Stapler Stress In the early days of Microsoft Office, testers were very creative with their office supplies The goal was to simulate real user input from a keyboard that would overload the program's input buffer The challenge was finding the proper office accessory that was the right size with the proper dimensions that could easily be applied to the keyboard while I went to lunch As it turns out, the stapler fit the task When I came back from lunch, there was always an ASSERT or Hard Crash on my screen Craig Fleischman, Test Manager The USB Cart of Death During the Windows 2000 project, we had an interesting way to test Plug and Play We created the "USB Cart of Death" We started with a two-level cart similar to what you'd see in a library. The .NET Framework provides three basic types of configuration files: machine, application, and security. Despite their different contents and goals, all configuration files are XML files and share the same schema. For example, all configuration files begin with a <configuration> node and then differentiate their contents and child nodes according to the final goal and the information contained. In this chapter, we'll focus primarily on application configuration files, but this section also provides a quick introduction to the other types of configuration files. For Native Code, Know Where Your DLLs Load If you've ever been hiking in the woods, you know that landmarks can be very important in keeping you from getting lost. When you don't have any landmarks, you can end up going around in circles. When your application crashes, you need a similar kind of landmark to help point you in the right direction so that you're not wandering around in the debugger. The first big landmark for crashes is the base address of your dynamic-link libraries (DLLs) and ActiveX controls (OCXs), which indicates where they loaded into memory. When a customer gives you a crash address, you should be able to narrow down which DLL it came from quickly by the first two or three numbers. I don't expect you to have all the system 38 DLLs memorized, but you should memorize at least the DLL base addresses for the DLLs in your project If all your DLLs load at unique addresses, you have some good landmarks to help guide your search for the crash But what do you think would happen if all your DLLs had the same load address Obviously, the operating system doesn't map them all into the same place in memory It has to "relocate" any incoming DLL that wants to occupy memory that's already filled by putting the incoming DLL into a different place The issue then becomes one of trying to figure out which DLL is loaded where Unfortunately, you have no way of knowing what the operating system will do on different machines This means you'll get a crash address and literally have no idea where that address came from. The XML Schema for Configuration Settings As mentioned, configuration files are standard XML files that follow a particular schema This schema defines all possible configuration settings for machine, security, and application configuration files The NET Framework provides you with ad hoc classes to read configuration settings, but no writing can be performed You need to be familiar with XML readers and writers if you want to directly edit the configuration files (In light of this, bear in mind that XML elements and attribute names are case-sensitive) All the configuration files are rooted in the <configuration> element Table 15-1 lists the first-level children of the <configuration> element Each node has a specified number of child elements that provide a full description of the setting For example, the <system. About 10 eight-port hubs were wired together, and then every port was filled with some different type of USB device A USB steering wheel adorned the back of the cart, and a USB radio provided the antenna Two cameras were on the front All power went to a USB uninterruptible power supply (UPS) The entire cart, completely mobile, came down to two cables (power, USB) The final USB cable was plugged into a USB PCMCIA card We'd plug the card into a laptop, watch the operating system start up the 50 or so devices on it, and then (either before or after it finished) we'd unceremoniously yank the PCMCIA card If a blue screen occurred, or if another error occurred, the appropriate developer would be asked to look at the computer. And that means your boss will be extremely upset because you can't tell him why the application died By default for wizard-created projects, Visual Basic 6 ActiveX DLLs load at 0x11000000, and Visual C++ DLLs load at 0x10000000 I'm willing to bet that at least half the DLLs in the world today try to load at one of those addresses Changing the base address for your DLL is called rebasing, and it's a simple operation in which you specify a load address different from the default Before we jump into rebasing, let's look at two easy ways to find out whether you have load conflicts in your DLLs The first way is to use the Visual Studio NET debugger Modules window Run your application in Visual Studio . NET and display the Modules window, which is accessible from the Debug menu, Windows submenu, or by pressing CTRL+ALT+U with the default keyboard mapping If a module has been rebased, its icon displays a red ball with an exclamation point next to the name Additionally, the load address for the module has an asterisk after the address range Figure 2-7 shows where the SYMSRVDLL was relocated in the debugging session.. web> element optionally contains the <authorization> tag, in which you can store information about the users who can safely access the URL resources Table 15-1: Children of the <configuration> Element Element Description <appSettings> Contains custom application settings in the specified XML format Describes the configuration sections <configSections> for custom settings If this element is in a configuration file, it must be the first child of the <configuration> root <mscorlib>\<cryptographySettings> Cryptography schema; describes the elements that map friendly algorithm names to classes that implement cryptography algorithms <runtime> Run-time settings schema; describes the elements that configure assembly binding and run-time behavior Startup settings schema; contains the elements that specify which version of the common language runtime (CLR) must be used Describes the elements that specify trace switches and listeners that collect, store, and route messages Network schema; specifies elements to indicate how the . In the meantime, we would wheel the cart on to the next laptop, in hopes of finding a different bug Adrian Oney, Senior Development Lead. Figure 2-7: The Visual Studio .NET debugger Modules window with a relocated DLL The second way is to download the free Process Explorer, written by my good friend and onetime neighbor, Mark Russinovich, from Sysinternals (www.sysinternals.com). Process Explorer, as its name implies, shows you all sorts of information about your processes, for example, loaded DLLs and all open handles. It's such a useful tool that if you don't have it on your machines right now, stop immediately and go download it! Also, make sure to read 14 for additional hints and tricks you can use to make your debugging life easier with Process Explorer. Seeing whether you have relocated DLLs is very easy. Just follow the next set of steps. Figure 2-8 shows what it looks like to have relocated DLLs in a process. vb.net open pdf file in adobe reader Reference Adobe Reader dll to control pdf ? - Stack Overflow
