Figure 12-5: The IIS application mapping table for rem and soap URIs When IIS detects a remoting call, it passes the call to the ad hoc HTTP handler registered to handle soap and rem resources Although the object URI gives the impression of being a URL that is, a true server-side resource it is only a name and should in no way correspond to a physical file Whether the URI should be a string or the name of a physical resource depends on the expectations of the handler The remoting handler uses soap and rem URIs as strings to retrieve the proxy for the type Singleton Objects When an object declares itself as a Singleton type, the host application uses only a single instance of the object to service all incoming calls So when a call arrives, the host attempts to locate the running instance of the object. vb.net extract text from pdf: How to read PDF files in VB . net or convert PDF to word document in ... itextsharp read pdf fields vb.net How to extract text from PDF by pages in C#, VB .

They found that in certain cases it was much faster to poll than to actually perform an operation We've all been told since we were wee programmers never to poll, but in the case of critical sections, that's exactly what you want to do The vast majority of critical-section protection was for small data protection cases As I described in the last section, a critical section is protected by a semaphore, and making the call into kernel mode to acquire that critical section is extremely expensive The original implementation of EnterCriticalSection simply looked to see whether the critical section could be acquired If it couldn't, EnterCriticalSection went right into kernel mode In most cases, by the time the thread got into kernel mode and back down, the other thread had released the critical section a million years ago in computer time. vb.net read pdf content: PDF viewer VB .

One aspect of a riskbased approach attempts to classify which portion of the product contains these popular user scenarios and drives the creation of more tests directed at that portion of the product. The other side of the risk in this approach is that this approach relies on accurately determining where the majority of the testing effort should be and misses the fact that there will be customers who will use the features and code paths that fall outside of the 20 percent range. Another manner in which to apply risk-based testing is to write more tests for the parts of the product that have a higher potential of containing bugs. Just as my uncle knows where to cast his line to have the best chance of catching a fish, a risk-based testing approach knows which tests to run to have the best chance of finding critical bugs. vb.net read pdf file itextsharp How to Convert PDF to Text in .

You can't read and parse the contents of a PDF using iTextSharp like ... an existing PDF file using iText, you can only ' read ' it page per page. The counterintuitive idea the Microsoft researchers came up with on multiple CPU systems was to check whether the critical section was available and, if it wasn't, spin the CPU, then check again On single CPU systems, the spin count, obviously, is ignored If after the second check the critical section wasn't available, finally transition to kernel mode The idea was that keeping the thread in user mode, even though it was spinning on nothing, was tremendously faster than transitioning to kernel mode Two functions allow you to set the critical-section spin count The first is InitializeCriticalSectionAndSpinCount, which you should use in place of InitializeCriticalSection For the second function, SetCriticalSectionSpinCount, you want to change the value you originally started with, or you need to change the value for library code that uses only InitializeCriticalSection Of course, I am assuming that you can access the critical-section pointer in your derived code. If such an instance exists, the request for execution is processed Otherwise, the host creates the unique instance of the remote class (using the default constructor) and forwards the request to it What happens if two requests arrive at the same time The NET Remoting subsystem arranges for them to be automatically serviced by distinct threads This requires that Singleton objects be thread-safe Note that this is not a mandatory programming rule but is more of a practical guideline for real-world scenarios State management for Singleton objects is certainly possible in theory, but it must be coded in the body of the object in much the same way as you do with Active Server Pages (ASP) and Microsoft ASPNET pages and even Web services The idea is that you use a shared cache that all clients can access (a sort of ASP. Determining your spin count can be problematic If you work in an environment in which you have the two to three weeks to run through all the scenarios, grab all those interns sitting around and have fun However, most of us aren't that lucky I always use the value 4,000 for my spin count That's what Microsoft uses for the operating system heaps, and I always figured that my code was probably less intensive than those Using that number also would be big enough should I keep my code in user mode almost all the time 531. [1]Wikipedia, Don't Use CreateThread/ExitThread One of the more insidious mistakes that people make in multithreaded development is using CreateThread Of course, that begs this question: if you can't use CreateThread to start a thread, how can you get any threads cranked up Instead of CreateThread, you should always use _beginthreadex, the C run-time function to start your threads As you'd expect, since ExitThread is paired with CreateThread to end a thread, _beginthreadex has its own matching exit function, _exitthreadex, that you'll need to use instead as well You might be using CreateThread in your application right now and not be experiencing any problems whatsoever Unfortunately, some very subtle bugs can occur because the C run time is not initialized when you use CreateThread The C run time relies on some perthread data, so certain standard C run-time functions designed before high speed multithreaded applications were the norm. NET Application object), unless you apply a filter on a per-client basis (a sort of ASPNET Session object) The lifetime of a Singleton well-known object is managed by the NET Remoting system through a special module called the lease manager (LM) (See the section "Memory Management," on page 551, for more information). Complexity is everywhere I remember making chocolate chip cookies ever since I was old enough to reach the knobs on the oven I used my grandmother's recipe, and it only included a few ingredients I rarely referred to the recipe, but the cookies were perfect every time The measurements of the various ingredients were consistent (that is, two sticks of butter, two cups of flour, one cup each of white and brown sugar, and one bag of chocolate chips), and the cooking time was a round number (10 minutes) The key to my success was that the recipe was simple Barring a catastrophe (such as rancid butter or a broken oven), I could not find a way to make bad chocolate chip cookies. For example, the function strtok holds the string to parse in per-thread storage Using _beginthreadex ensures that the per-thread data is there along with other things the C run time needs To ensure proper thread cleanup, use _exitthreadex, which will ensure the C run time resources are cleaned up when you need to exit the thread prematurely The _beginthreadex function works the same way and takes the same type of parameters as CreateThread To end your thread, simply return from the thread function or call _endthreadex However, if you want to leave early, use the _endthreadex C run time function to end your threads As with the CreateThread API function, _beginthreadex returns the thread handle, which you must pass to CloseHandle to avoid a handle leak If you look up _beginthreadex, you'll also see a C run time function named _beginthread. You'll want to avoid using that function like the plague because its default behavior is a bug, in my opinion The handle returned by _beginthread is cached, so if the thread ends quickly, another spawned thread could overwrite that location In fact, the documentation on _beginthread indicates that it's safer to use _beginthreadex When reviewing your code, make sure to note calls to _beginthread and _endthread so that you can change them to _beginthreadex and _endthreadex, respectively The Default Memory Manager Might Kill You A client of ours wanted to make the fastest possible server application When they brought us in to tune the application, they found that adding threads to the application, which according to their design should have scaled the processing power, was having no affect. SingleCall Objects A well-known type declared as a SingleCall object has a new instance of it created whenever a request arrives The host application creates a new instance of the SingleCall object, executes the requested method, and then routes any return values back to the client After that, the object goes out of scope and is left to the garbage collector Although it's not completely impossible, preserving state from one call to the next is realistically a bit impractical for SingleCall objects In this case, the lifetime of the object instance is extremely short and barely covers the duration of the method call You can try either storing information in a database (or any sort of persistent storage medium) or parking data in other objects with a different lifetime scheme. As an adult, I still love to cook, but I have run into various problems many times in the kitchen while attempting to reproduce a favorite dish or re-create a recipe inspired by the pictures included in some of my cookbooks Recipes with dozens of ingredients and multiple cooking steps are primed for mistakes to happen Usually, I make it through unscathed, but often enough, I end up with three pans cooking on the stove before I realize that I missed an entire step or misread the recipe and put a tablespoon of cayenne pepper into the soup instead of a teaspoon The complexity of the recipe and the interaction of dealing with multiple recipes at once make it more likely that I will make a mistake Similarly, complex code and interactions of complex portions of code are generally more prone to mistakes. read pdf file using itextsharp vb.net PDF to Text - CodeProject
