13 Mar 2013 ... VB . NET doesn't have a built in PDF file reader object, but a third party product called iTextSharp fills the bill nicely. Hannes du Preez ... Using IIS as the activation agent is natural when you plan to expose the same remote service through .NET Remoting and Web services. So let's assume in our example application that IIS is the activation agent and SalesReport is the virtual directory. Activation Policies In addition to the remotable object's identity, channels, and ports, the server configuration file also contains another important piece of information the object activation policy. An MBR remotable object can be either server-activated or clientactivated. Server-activated objects are created by the server only when the client invokes the first method through the local proxy. Client-activated objects are created on the server as soon as the client instantiates the object using either the new operator or methods of the System.Activator class. In addition, server-activated objects can be declared as Singleton or SingleCall objects. A Singleton object has exactly one instance to serve all possible clients. A SingleCall object, on the other hand, requires that each incoming call is served by a new instance of the remotable object. A remotable object declares its required activation policy in the configuration file through specific subtrees placed below the <application> node. Server-Side Activation Server-activated objects are remotable objects whose entire life cycle is directly controlled by the host application. Server-activated objects are instantiated on the 441 vb.net code to extract text from pdf: Reading PDF content with itextsharp dll in VB .

The constructor for a wrapper class such as CUseCriticalSection is called at the top of the scope, where it's declared and destroyed when that scope ends. Nearly everyone uses the synchronization class as it is shown in the following code: void DoSomethingMultithreaded ( ) { CUseCriticalSection ( g_lpCS ) ; : ( (LPCRITICAL_SECTION)&(m_cs( ( LPCRITICAL_SECTION)&(m_cs: CUseCriticalSection ( const CCriticalSection & cs ) : CRITICAL_SECTION m_CritSec ; vb.net read pdf file itextsharp How to read and extract data from pdf file in vb | The ASP.

CUseCriticalSection ( void ) Basis path testing is different from block and decision testing in that each outcome for each conditional clause must be tested independently. For example, it is possible to evaluate the conditional clause in a while or for loop to both its true and false outcomes with one (poorly designed) test to satisfy decision or block testing. However, basis path testing requires one test that forces control flow to bypass the loop and another test in which program control flows through the looping structure. So, similar to condition coverage, basis path testing subsumes both block and decision testing. Basis path testing provides better sensitivity to control flow as compared to block or decision testing when analyzing a function composed of simple conditional clauses, especially those employing looping structures. But basis path testing appears to produce similar results to condition testing when evaluating a compound conditional clause. H. Watson and Thomas J. McCabe, Structured Testing: A Testing Methodology Using the Cyclomatic Complexity Metric, NIST Special Publication 500-235 (Gaithersburg, MD: National Institute of Standards and Technology, 1996). NET Remoting system knows that any object of type ServiceSalesProvider is just a local proxy for a remote object When the client calls new or SystemActivator on the well-known type, only the remoting proxy is created in the client application domain The real instantiation of the object will take place on the server at a later time, when a non-null instance is needed to serve the first method call Because the constructor is called implicitly and outside the control of the client, only the default constructor is supported This means that if your class has a constructor that takes some arguments, that constructor is never taken into account by the host application and never used to create instances of the remotable class Note As part of the NET Framework reflection API, the System. for ( ) { CallSomeOtherFunction ( ) ; } // Here's the only piece of data really needing protection m_xFoo = z ; YetAnotherCallHere ( ) ; } The constructor grabs the critical section at the top curly brace, that is, right after the prolog, yet the destructor is not called until the bottom curly brace, right before the epilog That means you hold onto the critical section for the life of the function, even though DoSomethingMultithreaded is probably calling functions that don't need to be holding onto the critical section All you are succeeding in doing is killing performance As you look at DoSomethingMultithreaded, you're probably thinking, "How expensive can acquiring a synchronization object really be " If there's no contention for the synchronization object, the cost is very small. However, with multiple threads, the instant a thread can't acquire a synchronization object, you begin a potentially astronomical cost! Let's start by taking a look at what happens when you call WaitForSingleObject to acquire a synchronization object Since you are an assembly language demigod from reading 7, you might want to follow along in the Disassembly window as it will show you exactly what I'm about to discuss Note that I'm doing the work on Windows XP; the Windows 2000 version of WaitForSingleObject might be slightly different WaitForSingleObject itself is simply a wrapper around WaitForSingleObjectEx, which does about 40 lines or so of assembly language and calls two functions to set up some data Down toward the bottom of WaitForSingleObjectEx is a call to NtWaitForSingleObject from NTDLLDLL So the WaitForSingleObject function is a call to a wrapper of a wrapper. Summary Activator object provides a CreateInstance method that you can use to create instances of dynamically determined types (Instantiating types this way is a kind of NET Framework late binding) Interestingly, this method supports a nice feature that would have fit well in the NET Remoting system too (and hopefully will in a future version) The CreateInstance method has an overload that takes an array of object objects It then uses the size of the array and the actual types boxed in the various objects to match one of the constructors declared on the target type However, maybe for performance concerns or perhaps just to simplify the feature, the NET Remoting infrastructure does not supply this facility.. If you disassemble the address where NtWaitForSingleObject is in memory (use {,,ntdll}_NtWaitForSingleObject@12 in the Address field of the Disassembly window), you'll see that it's really a call to some weird function, ZwWaitForSingleObject, which is also out of NTDLLDLL (On Windows 2000, you'll stop at NtWaitForSingleObject) As you look at the disassembly for ZwWaitForSingleObject, you'll see that it looks something like the following: _ZwWaitForSingleObject@12: 77F7F4A3 77F7F4A8 77F7F4AD 77F7F4AF 77F7F4B2 mov mov call ret nop eax,10Fh edx,7FFE0300h edx 0Ch. Structural testing techniques are systematic procedures that help testers design effective tests more efficiently when analyzing the program's source code to improve code coverage. But we would never advocate structural testing as the initial or the only approach to testing software. Structural testing techniques are designed to support and enhance other testing approaches and methods. Structural testing can also provide more in-depth information and reduce risk exposure by designing and executing tests to evaluate paths through the code that were not traversed by other testing approaches. This is important because logic errors are inversely relational to a path's probability of execution. If we don't execute a path through code, we must assume 100 percent risk. If we execute that path, our risk is The real action is at that address, 0x7FFE0300. If you dump what's at that address, you'll see the following: 7FFE0300 mov edx,esp 7FFE0302 sysenter 529 If you need to publish a remotable type whose instances must be created using a specific, nondefault constructor, you should resort to client activation. Well-Known Objects From the perspective of a .NET Remoting client, server-activated objects are said to be well-known objects. Well-known objects have two possible working modes: Singleton and SingleCall. In the former case, one instance of the object services all calls from all clients. In the latter case, a new instance of the object is created to service each call. A well-known object declares its working mode using the <wellknown> tag in the configuration file under the <service> tag, as shown here: <service> <wellknown mode="SingleCall" type="XmlNet.CS.ServiceSalesProvider, ServiceSalesProvider" objectUri="ServiceSalesProvider.rem" /> 442 The middle line in the preceding code, showing the SYSENTER, is the magical assembly language instruction It's one that you'll see only in this context and you won't ever see generated in your code, so I didn't cover it in 7 Just from the name you can probably guess what it does: it's the instruction that transitions you from user mode to kernel mode On Windows 2000, the INT 2E call does the same thing as the SYSENTER instruction. vb.net extract text from pdf How to Read PDF and Convert to Stream in C#/ VB
