Voice of the customer can be gathered from multiple sources. Direct surveys of customer satisfaction are the most common. Many services teams have shifted from using direct surveys of customer satisfaction to the Net Promoter score. Blog and Twitter mining is another way to see what customers are saying about your product or service. The Net Promoter score is a management tool that can be used to gauge the loyalty of a firm's customer relationships. It serves as an alternative to traditional customer satisfaction research. For services with direct support, call center data is a vital component of voice of the customer. Whether through actual phone calls or online chat help, user requests are categorized. By mining this data, a service team can identify the top customer escalations and prioritize those to improve customer satisfaction but also drive down the support costs. Product quality focuses on bugs and performance. In many cases, bugs might already be known, but how important they are to fix relative to other bugs is often hard to determine. A major area of product quality is the continual measurement and improvement of page load time relative to competitors. What is good performance today is not necessarily a customer satisfaction driver in the future.

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 ... It can be a string representing a node name or another XPathExpression object that evaluates to a node name In the first overload, the comparer argument refers to an instance of a class that implements the IComparer interface The interface supplies a Compare method that is actually used for comparing a pair of values Use this overload if you need to specify a custom algorithm to sort nodes Using the Comparer Object To sort arrays of objects, the NET Framework provides a few predefined comparer classes, including Comparer and CaseInsensitiveComparer The former class compares objects (including strings) with respect to the case The latter class does the same, but irrespective of the case To use both classes in your code, be sure to import the SystemCollections namespace The Comparer class has no public constructor but provides a singleton instance through the Default static property, as shown here: expr. vb.net print pdf: How to create PDF files in vb.net - Print Source Code vb.net read pdf fields PDF Viewer Control Without Acrobat Reader Installed - CodeProject

Hi, I need to read and parse a PDF file that has 50,000 pages. The "Save As" option within the Acrobat Reader is not of much use. The PDF file ... efficiencies, but in a QoS approach it is used to identify potential dissatisfaction (DSat) drivers I often like to kid with the operations engineers, saying that there is little they can do to drive up customer satisfaction but a lot they can do to drive it down This fact doesn't put operations in a very fun position, which is why it can be a challenging role Here are a few key operational metrics and how they can be used to improve QoS: Root cause analysis (RCA) on any production outage can identify either a process problem or an underlying bug or architecture flaw A high time to detection for a production issue can show holes in monitoring A high time to resolution can indicate inadequate logging or diagnostic tools Percentage of tickets resolved through Tier 1 or a self-healing system can show efficiency of handling simple, high-volume production issues. handed to your exported function, stored in GetRealAddress, to get the real address for the variable. You'll pass that value on to ReadDebuggeeMemoryEx in order to get the bytes for the type. The beauty of the helper class is that it completely hides the magic necessary to get the data out of local and remote debuggee processes. Listing 7-1: EEAddIn export prototype and helper structure /*-------------------------------------------------------------------The only definition of the Expression Evaluator AddIns Lifted from The EEAddIn Sample Project --------------------------------------------------------------------*/ typedef struct tagDEBUGHELPER { DWORD dwVersion ; BOOL (WINAPI *ReadDebuggeeMemory)( struct tagDEBUGHELPER * pThis , DWORD dwAddr , DWORD nWant , VOID * pWhere , DWORD * ); // from here only when dwVersion >= 0x20000 DWORDLONG (WINAPI *GetRealAddress)( struct tagDEBUGHELPER *pThis ) ; BOOL (WINAPI *ReadDebuggeeMemoryEx)( struct tagDEBUGHELPER *pThis , DWORDLONG qwAddr , DWORD nWant , VOID* pWhere , DWORD * nGot ; 252 ); int (WINAPI *GetProcessorType)( struct tagDEBUGHELPER *pThis ) nGot string strX = (string) x; string strY = (string) y; Resolving at Tier 1 or in an automated selfhealing system also brings down time to resolution Percentage of false alarms can show errors in monitoring or alert thresholds The richest area for finding product improvements is tickets by bucket This is very similar to the call center coding but is the operational view instead of the customer perspective Any area that has a high count is rich for product improvement or self-healing automation When all three data sources are brought together, the team can better prioritize the right fixes to maximize improvements to customer satisfaction Here is an example of how this could work in a very layered service: The call center team has a high number of complaints from users that could not process PayPal payments on the evening of June 23. } DEBUGHELPER ; // The prototype each of your functions must be. typedef HRESULT (WINAPI *CUSTOMVIEWER)( DWORD , DEBUGHELPER * , int , BOOL , char * , size_t , DWORD ) ; reserved max pResult bUniStrings nBase dwAddress pHelper Your exported function's job is to convert those bytes read in from the debuggee into something displayable in the Watch window Since you can easily read the memory out of the debuggee, you'll be working with a copy of the information When I first got a glimpse of the EEAddIn architecture, I immediately thought of a million cool displays I would love to have The first was one that would take an HINSTANCE or HMODULE and show the value followed by the name of the DLL at that location Of course, reality then intruded Converting an HINSTANCE or HMODULE into a DLL name required a handle to the process The DEBUGHELPER structure in Listing 7-1 gives you a way to read memory but not get the process handle. // 0 if equals, >0 if x>y, <0 if x<y return StringCompare(strX, strY); } } This class can also be defined within the body of your application and does not necessarily require a separate assembly The second overload of the AddSort method always performs a numeric or text comparison according to the value of the dataType argument In addition, you can specify a sorting order (ascending or descending) and even the sort order for uppercase and lowercase letters In practice, you can decide whether lowercase letters must come before or after uppercase letters The constant XmlCaseOrderNone simply ignores the case Finally, the lang argument indicates the language to use for comparison for example, "us-en" for US English The following code snippet selects all the <Employee> nodes from our original sample XML file This time, we make use of a compiled expression with sorting capabilities. When enough calls about a common problem have come into the call center an alert is sent to the live site operations team Upon investigation they discover that PayPal has updated a certificate on their service that requires any other service trying to connect to them to also update to the new version Certificates are essentially private keys services use to identify trusted partners Upon review of this incident the call center, operations team, and product engineering team identify a gap in the service monitoring and agree to implement a PayPal monitoring solution and an alert system for when certificates need to be updated The solution to add an alert will warn the operations team when the certificate is due to expire and thus prevent a future outage On the off chance that this does happen again, the enhanced monitoring will reduce the time to detection and time to resolution. Of course, that's when I realized that if my EEAddIn function was working on a process being debugged remotely, even having the process handle wouldn't help because I couldn't do anything with that handle on the machine the debugger was running on Maybe a future version of Visual Studio NET will offer a means of querying information from the process that needs handle values Even with the restriction that you can read only the debuggee's memory, plenty of excellent opportunities to put better displays in the Watch window are still open to you so that you can debug faster Included with this book's sample code is my current EEAddIn, BSU_ExpEval_AddIn At the time I wrote this paragraph, I incorporated the _SYSTEMTIME and _FILETIME displays from the sample provided by Visual Studio, but I put error handling around them as well as the following structure expansions: _OSVERSIONINFOA, _OSVERSIONINFOW, _OSVERSIONINFOEXA, and _OSVERSIONINFOEXW. XPathDocument doc = new XPathDocument(fileName); XPathNavigator nav = docCreateNavigator(); XPathExpression expr; expr = navCompile("/MyDataSet/NorthwindEmployees/Employee"); exprAddSort("lastname", XmlSortOrderAscending, XmlCaseOrderNone, "", XmlDataTypeText); XPathNodeIterator iterator = navSelect(expr); The iterator now returns nodes sorted in ascending order on the values stored in the lastname child nodes Is there a way to sort by multiple fields As mentioned, the expr argument of the AddSort method can also be an XPath expression, and by exploiting this feature, you can involve more nodes in the sort process When sorting database tables, you normally indicate the sortable columns in a comma-separated string In this case, you must provide a valid XPath expression The expression will be evaluated to a string and the actual value used to sort nodes. Now when you have one of the structures handled by GetVersionEx, you can see them displayed as shown in Figure 7-5, which shows some of the output of the test program for BSU_ExpEval_AddIn Listing 7-2 shows the work necessary to expand the _OSVERSIONINFOA structure.. vb.net open pdf file in adobe reader C# 4.0: Convert pdf to byte [] and vice versa - Stack Overflow
