You can use the ITextSharp assembly to get values and manipulate forms in pdf . You can download it here.[^] Here's a simple tutorial to use it. The biggest impact to page load time is the network. As the distance from the source to the client increases, the network becomes an increasingly influential component of page load time. Reducing page weight reduces the amount of data, but it is really the number of round trips that most affects PLT. VRTA3 and Fiddler can help with this analysis, and VRTA3 does have some nice graphical representations that help. VRTA Used to Find Bugs in Internet Explorer VRTA was designed to help engineers visualize the download of a Web page. I have been using this technique inside of Microsoft for the past four years. Presenting this process in a very visual way so that the engineers can see what items are serialized behind each other has helped improve page load times for many services. The tool has also helped to identify some of the more difficult to diagnose issues in browsers. One problem we found in Microsoft Internet Explorer 7 was the JavaScript blocking behavior, which restricted the number of files loading simultaneously. The effect was that parallel TCP ports were limited to only two. VRTA is also in active use for testing our new Internet Explorer 8 browser, but as of the writing of this book, that product hasn't shipped and I can't really share those bugs just yet. Jim Pierson, Perf Architect, MSN and Windows Live The Microsoft Office Live team sets a threshold for the maximum number of round trips (un-cached) that each Web page can have. When the developer makes a check-in to the source control system, a suite of tests for performance run and any page exceeding the round trip threshold is flagged. itextsharp read pdf fields vb.net: Free .

In a PDF document, contents are often formed by text . If readers think that contents are useful for them or can be takes as template, they may need to extract text ... With the PROCESS_INFORMATION structure, I'm interested in looking at the hProcess and hThread values, so my autoexpand rule would be _PROCESS_INFORMATION =hProcess=<hProcess,X> hThread=<hThread,X>. I use the ,X format specifiers because I always want to see the values as hexadecimal values. Figure 7-4 shows the autoexpand rule for _PROCESS_INFORMATION showing up in a data tip in the source window. vb.net print pdf to specific printer: PLEASE explain to me by VB . net code how to print a given path PDF ... vb.net pdf read VB .

NET XPath processor is designed to look for the namespace manager on the XPath expression object prior to proceeding Evaluating Expressions As mentioned, when evaluated, an XPath expression can return any of four basic types: node-set, Boolean, number, or string If the return type is a node-set, you can run the expression through both the Select method and the Evaluate method The Select method returns an object of type XPathNodeIterator that you can use to walk your way through the members of the node-set Unlike Select, the Evaluate method returns a generic object type, which it is your responsibility to cast to the correct strong type, as in the following example: XPathNodeIterator iterator = (XPathNodeIterator) navEvaluate(expr); Expressions that do not return a node-set can be used only with the Evaluate method. vb.net open pdf file in adobe reader Read and Extract PDF Text from C# / VB .

7 Jul 2018 ... This Quick Tip shows you how to display a PDF with VB . NET . ... probably use to display PDF files anyway: the free Adobe Acrobat PDF Reader . Figure 7-4: Autoexpand in a data tip When entering my new autoexpand rule, I must place it after the section of the AUTOEXP.DAT file delineated by [AutoExpand]. Your best bet is to place your values right after [AutoExpand] so that you can find them easily and not mess up the techniques I'll discuss in the next section. The good news is that unlike the managed debugging autoexpands that are read only when you start Visual Studio .NET, the AUTOEXP.DAT file is read in each time you debug, so developing native autoexpand rules is much easier. One special formatting code you'll see in the file is <,t>. This code tells the debugger to put in the type name of the most derived type. For example, if you have a base class A with a derived class B and only A has an autoexpand rule, the autoexpand for a variable of type B will be the class name B followed by the autoexpand rule for class A. The <,t> format is very helpful for keeping your classes straight. In this section, I want to share a bit more on testing in an S+S world. Although these points didn't really fit well under test techniques, each contains information that any tester on a service should champion. In this case, however, you must also cast the returned object to a strong type, as shown here: string buf = (string) navEvaluate(expr); The Evaluate method has no effect on the state of the navigator An interesting overload for the method is shown here: public object Evaluate( XPathExpression expr, XPathNodeIterator context ); 226 = new. Adding Your Own HRESULT Values In addition to expanding your types, the Visual Studio NET Watch window now has provisions to show your custom HRESULT values as text instead of as some hard-todecipher number The magical AUTOEXPDAT also holds these values At the end of the AUTOEXPDAT file, add a new section named [hresult] and add each custom HRESULT using the following pattern: "<unsigned decimal value>=<HRESULT text>" The code that follows is an example that includes some of the values not handled automatically by the debugger If you'd like to see the actual HRESULT value for one of the built-in conversions or one you've added to the [hresult] section, take the HRESULT variable and append ,u or ,x to the variable That will force the variable to be displayed as an unsigned integer or a hexadecimal value, respectively. [hresult] 2147500051=CO_E_CANT_REMOTE 2147500056=CO_E_CREATEPROCESS_FAILURE 2147500059=CO_E_LAUNCH_PERMSSION_DENIED Adding Super Customized Display to the Watch Window A major enhancement to the Watch window that's shown up for native debugging is the Expression Evaluator Add-In (EEAddIn) What EEAddIn allows you to do is to have the debugger call one of your DLLs when the Watch window is evaluating a specific type This gives you an excellent opportunity to provide calculations that will display data in a more relevant way For example, the Watch window will display a SYSTEMTIME structure (which represents the Win32 date and time) as a bunch of hexadecimal numbers, making it impossible for you to determine the time When you use an EEAddIn, the Watch window displays a readable string such as {5/13/2002 12:51 AM} instead. In 3, "Engineering Life Cycles," we discussed the concept of Milestone Q (a.k.a. MQ or M0). For larger projects, this milestone is typically about clearing the decks and getting ready for the next major release. Teams invest in infrastructure improvements to help the process of developing and shipping to be smoother and faster. Developers often investigate new technologies and develop new prototypes. In the services world, where teams might go years shipping monthly or quarterly, we don't often take time for an MQ. In the services world, we focus on continuous improvement. All of our production services are very data driven and most use a very Six Sigma-like process we call quality of service (QoS) to drive continuous improvement. This QoS should not be confused with the computer networking concept that gives certain applications priority network access over others. Our version of QoS is about finding the unique insights that will help us to improve customer satisfaction. A successful QoS program must have data from three major categories. It can include other data, but in many cases that can distract from the very clear goal of improving customer satisfaction. The three major categories of data are voice of the customer, product quality, and operational quality, as shown in Figure 14-11. Normally, the expression is evaluated using the current node in the navigator as the context node Using this overload, however, you can control the context node for the expression If the context argument is null, the method works as usual Otherwise, if context points to a valid iterator object, the current node in the iterator is used to determine the context node for the XPath expression Sorting the Node-Set An interesting extension to the XPath programming model built into the XPathExpression class and the XPath processor is the ability to sort the node-set before it is passed back to the caller To add a sorting algorithm, call the AddSort method of the XPathExpression object AddSort allows for two overloads, as follows: public void AddSort( object expr, IComparer comparer ); public void AddSort( object expr, XmlSortOrder order, XmlCaseOrder caseOrder, string lang, XmlDataType dataType ); The expr argument denotes the sort key. To tell the Watch window you have an EEAddIn DLL you'd like to load, you place an entry for each type you want to evaluate in the ubiquitous AUTOEXPDAT file Under the [AutoExpand] section, you'll indicate the expansion for a type using the following syntax: type name=$ADDIN(dll name,exported function) The type name is, as with the autoexpand rules, the name for the type the Watch window displays in the Type column for the variable The DLL name is the name of the DLL The documentation for the EEAddIn, which is just sample Visual Studio NET project named, appropriately, EEAddIn, indicates that the DLL name just needs to be the name of the DLL because you're supposed to put your EEAddIns in the same directory as AUTOEXPDAT. However, I've found that you should indicate the complete path to the DLL as part of the DLL name to ensure proper loading The exported function is the function you want called to process your custom display for the given type Since your EEAddIns run in the address space of the debugger, you need to ensure that you properly handle any possible exceptions because you'll crash the debugger if you don't The individual exported functions must match the CUSTOMVIEWER prototype, as shown in Listing 7-1 When your function is called, it will receive as parameters the address of the type; a pointer to a helper structure, DEBUGHELPER; the numeric base currently selected (decimal or hexadecimal); a Boolean value indicating whether the debugger is expecting UNICODE strings (which in Visual Studio . vb.net read pdf fields reading a pdf document with iTestsharp | The ASP.
