One of the first things I did when their server application was warmed up and cooking along was to stop it in the debugger and, from the Threads window, look at where each thread was sitting This application made use of quite a bit of the Standard Template Library (STL), which as I pointed when discussing WinDBG in the "Trace and Watch Data" section of 8, can be a performance killer all its own because it allocates tons of memory behind your back By stopping the server application, I was looking to see which threads were in the C run time memory management system We all have the memory management code (you install the C run time source code every time you install Microsoft Visual Studio, right ), and I'd seen that a single critical section protects the whole memory management system. vb.net pdf read text: C# / VB .

NET Barcode Reading and Recognition. No Star. (0). Client-Side Activation Client-activated objects are instantiated on the client as the result of a call to the new operator or to the SystemActivator object Each remoting client runs its own copy of the object and can control it at will For example, the client can use any of the available constructors In addition, persisting the state during the session is straightforward and does not require any special coding On the down side, sharing state between clients is difficult, and to do so, you must resort to a database, a disk file, or any other global object in the current AppDomain The following code snippet shows how to change the contents of the <service> tag to reflect a client-activated object Instead of the <wellknown> tag, you use the <activated> tag This tag supports only the type attribute No object URI is necessary with client-activated objects. vb.net itextsharp pdfreader: PDF Viewer SDK Control x64 - Visual Studio Marketplace vb.net code to extract text from pdf How to extract text from a PDF file in C#, VB .

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 ... That was always scary to me because I thought it could lead to performance issues When I looked at our client's application, I was horrified to see that 38 out of 50 threads were blocked on the C run-time memory management critical section! More than half of their 532. One method sometimes used to predict where bugs might be is to seek out the areas where the code is more complicated Complex code has a tendency to have more bugs, and simple code tends to have fewer bugs Complicated code also has the enormous drawback of being much more difficult to maintain Code complexity is an important measure of the "difficulty" of the code The greater the complexity of the code, the more difficult the code is to test Gut feel or subjective measurement from cursory code review is at times sufficient for gauging code complexity Code smell is a term used often in Agile programming circles that describes code that might be too complex because of large functions or a large number of dependencies. vb.net extract text from pdf Read a PDF Line by Line - iTextSharp - Stack Overflow

You can't 'parse' an existing PDF file using iText , you can only ' read ' it page per page. What does this mean? The pdf format is just a canvas ... application was waiting and doing nothing! Needless to say, they were not very thrilled to find this out For most applications, the Microsoft supplied C run time is perfectly fine and will not cause you memory problems However, in the larger, high-volume server applications, that single critical section can eat you up My first recommendation is to always think long and hard about using STL, and if you insist on using STL, take a look at the STLPort version I discussed back in 2 I've already discussed numerous issues with STL earlier in this book In the context of high-volume, multithreaded applications, the Microsoft-supplied STL can lead to bottlenecks The bigger problem is what to do about the C run-time single critical section problem What we really need is each thread with its own heap instead of a single global heap for all threads. More precisely, the URI is still necessary, but because the activation occurs on the client and at a very specific moment in time, the URI can be silently generated by the NET Remoting infrastructure and attached to each call <service> <activated /> type="XmlNetCSServiceSalesProvider, ServiceSalesProvider". That way each thread would never make that kernel mode transition to allocate or deallocate memory Of course, you can probably see that the solution is not as simple as making a single heap per thread, because you have the problem of handling the case in which memory is allocated in one thread and deallocated in another Fortunately, there are three solutions to the conundrum The first solution is the commercial memory management systems on the market, which handle the per-thread heap code for you Unfortunately, the pricing models for those products are borderline extortion and your manager will never buy anything that expensive The second solution, one of the big performance boosts with Windows 2000, is the major improvements Microsoft made to how the operating system heaps work (those heaps created with HeapCreate and accessed with HeapAlloc and HeapFree). Smells are typically a subjective measurement that can depend on the programming language or environment, and they are useful for identifying code that potentially should be refactored or rewritten Don't Touch That When I worked on the Microsoft Windows 95 team, I tested networking components In one particular component I tested, we would occasionally find a minor bug, and on rare occasions, a beta user would report an issue with this component Luckily, all of the bugs were minor because all of the bugs in this component were resolved as "won't fix," meaning that a fix was not planned for this release or for any future release The reason for these resolutions was simple: The code was "too scary to touch" and the. To take advantage of the operating system heap, you can easily replace your malloc/free allocations with the appropriate Heap* functions For the C++ new and delete functions, you'll need to provide replacement global functions The third and last solution, if you'll be running on multiprocessor machines, is to use Emery Berger's excellent Hoard multiprocessor memory management code (http://wwwhoardorg) It's a drop-in replacement for the C and C++ memory routines and is very fast on multiprocessor machines If you have trouble getting it to link in because of duplicate symbols, you'll have to use the /FORCE:MULTIPLE command line option to LINKEXE Keep in mind that Hoard is for multiprocessor machines and can actually run slower than the default allocators on single processor systems. </service> As with Singleton objects, the lifetime of a client-activated object is controlled by the LM. The instance of the object remains active until the proxy is destroyed. Choosing the Activation Mode That Fits Theoretically, all the working modes examined up to now don't affect in any shape or fashion the way in which you code your remotable classes. For example, a clientactivated object is in no way different from a Singleton object. All options can be set declaratively and, again speaking theoretically, each object can be configured to work in different ways simply by changing a few entries in the server's configuration file. Intriguing as this possibility is, such flexibility is not realistic in practice because a realworld object might want to exploit in depth the specific features of a working mode. In other words, you should thoughtfully and carefully choose the configuration options for your remote object and then stick to that configuration as long as the user's requirements are stable. For example, if you determine that the Singleton mode is appropriate for your component, you will probably want to implement an internal state management engine to share some variables. When at a later time you decide to set the object to work say, in SingleCall mode the state management engine is somewhat useless. Let's analyze our ServiceSalesProvider class to determine the most appropriate options. To begin, the object needs to query a back-end database (Northwind). Even 445 Get the Dump in the Field One of the most frustrating experiences is when your program appears to be deadlocking in the field and no matter how hard you try, you can't duplicate the deadlock However, with the latest improvements in DBGHELPDLL, you should never want in that situation ever again The new minidump functions will allow you to take a snapshot of the deadlock so that you can debug it at your leisure In 13, I discussed the particulars of the minidump function and my improved wrapper around it, SnapCurrentProcessMiniDump, in BUGSLAYERUTILDLL To get the dump in the field, you'll want to create a background thread that simply creates and waits on an event When that event is signaled, it will call SnapCurrentProcessMiniDump, and snap the dump to disk The following pseudo code snippet shows the function. itextsharp read pdf fields vb.net How to read and extract data from pdf file in vb | The ASP.
