It shows how you can both read and write form fields using iTextSharp . extreme ranges of linear variables for simple independent parameters, it might be too simplistic in complex situations. For example, a more thorough data analysis suggests Jorgensen's formula can potentially overlook critical boundary conditions identified by an equivalence class subset denoting a range of values in the extreme minima and maxima range of a linear variable. Also, unique values in an equivalence class subset might not be the extreme ranges of a linear variable, or a particular equivalence class range of values might be more interesting to analyze compared to other values in that range. For example, Figure 5-4 illustrates the Microsoft Windows 874 ANSI code page. The extreme linear range of character code points for this ANSI character set extends from 0x00 to 0xFF. vb.net itextsharp pdfreader: C# / VB .

Can you tell me which line of code gives you that error? Here is a VB . NET solution based on ShravankumarKumar's solution. I'm using .Net 4.0 and itextsharp ... The CLR execution engine is highly optimized and will inline code like crazy to eke out a couple of clock cycle savings This means that although you think you might be seeing everything that's going on in your program, you're seeing only the calls and returns for methods that were not inlined and nothing for the inlined methods If you want a complete graph of all calls actually made in a program, you have two options for turning off inlining However, as you can imagine, disabling inlining can have a dramatic performance hit on the managed code The easiest way to turn off inlining is to OR in the COR_PRF_DISABLE_INLINING flag to ICorProfilerInfo::SetEventMask when processing the ICorProfilerCallback::Initialize notification The drawback is that COR_PRF_ DISABLE_INLINING is an immutable flag, so you've turned it off for the entire life of the process, no matter where your code executes. vb.net read pdf file contents: PDF READER in Visual Basic .

"… A second way, while allowing finer grained control, requires much more work on your part One of the JIT notifications you get is JITInlining, which as you can tell by the name, indicates that a function is being inlined into another function (You'll have to OR in COR_PRF_MONITOR_JIT_COMPILATION in the event mask to get the JIT notifications) The JITInlining parameters, in order, are the caller FunctionID, the callee 428. Figure 5-4: Windows ANSI code page 874. However, if the input parameter specifically excludes the use of unassigned character code points, several valid and invalid equivalence class subsets are required to define the ranges of assigned and unassigned character code points, as indicated in Table 5-3. Although the overall physical range extends from 0x00 through 0xFF, if you don't carefully analyze the boundaries between the assigned character code points and unassigned character code points, you could easily overlook a potential problem. Table 5-3: ECP Subsets of Assigned and unassigned Character Code Points for Windows ANSI Code Page 874 Open table as spreadsheet Assigned character code points Unassigned character code points 0x00-0x80 0x85 0x9 -0x97 0xA0-0xDA 0x81-0x84 0x86-0x90 0x98-0x9F 0xDB-0xDE Deleted rows are detected by matching the diffgr:id attribute of original rows in the DiffGram with the IDs of the rows in the current data instance Rows in the <diffgr:before> section that have no counterpart in the current data instance are first inserted in the table and then deleted Although this approach might appear a bit odd, it's probably the most sensible way to add a logically deleted row to a DataTable object Note The DataTable class provides two methods to delete child rows: Delete and Remove The Delete method deletes the row logically by changing the state of the row The row no longer appears in the Rows collection, but it is not detached from the DataTable object The Remove method, on the other hand, performs a physical deletion and detaches the row from the table. FunctionID (the function being inlined), and a pointer to a BOOL, which, if set to FALSE, will prevent inlining You could do some very interesting things with the JITInlining notification For example, you could leave inlining on for the NET Framework class library (FCL) classes but turn it off when executing non-FCL code You have to be careful, however, because the CLR will call JITInlining billions of times and your code will look up caller and/or callee FunctionID values, which could cause a much worse performance hit than simply disabling globally in the process Although you might think about storing the FunctionID values you do look up, keep in mind that the CLR garbage collector can rejiggle those values, so you'll have to handle garbage collection notifications to keep your data tables straight. The Function ID Mapper In addition to the very cool hooking functions, I need to tell you about one other special function: FunctionIDMapper The purpose of this function is to allow you to change the value of the FunctionID passed to the three separate hook functions The CLR calls it right before any of the hook functions You don't have to set the FunctionIDMapper function if you don't want to, but doing so can open up some very interesting development possibilities Setting the FunctionIDMapper is immutable and you should do it in the ICorProfilerCallback::Initialize method by passing the function pointer to ICorProfilerInfo::SetFunctionIDMapper One thing that caused me some problems is that the ProfilingDOC discussion of the function prototype is wrong The FunctionIDMapper function returns a UINT_PTR, the underlying type for a FunctionID, instead of the void documented. Improved analysis of boundary values that might not be at the extreme ranges for an independent parameter requires an alternative approach and a different formula for calculating the minimum set of test data for basic boundary value analysis It should be clear that effective boundary value analysis relies on our ability as testers to identify accurately all unique boundary conditions for any given independent parameter Equivalence class subsets are also valuable in helping us identify potential boundary conditions The ECP subsets not only reveal the extreme linear ranges of values, but if the variable data is accurately decomposed, the ECP subsets also expose several values that might indicate additional important boundary conditions After identifying all boundary conditions for independent input and output parameters a minimum set of test data can be calculated with a simple formula: 3(BC), where BC is equal to the number of specific boundary conditions. The detached DataRow object is not automatically destroyed and remains valid as long as it does not go out of scope (Out of scope objects are automatically garbage-collected and destroyed) Valid DataRow objects can be readded to the same DataTable object (or to another DataTable object) at any time.. The correct prototype is this: UINT_PTR __stdcall FunctionIDMapper ( FunctionID functionId , BOOL *pbHookFunction ) ; Interestingly, FunctionIDMapper is a normal standard call function, not one of the naked functions required by the other hook functions The FunctionID parameter is the function that the CLR is about to call one of the hook functions for The Boolean pointer parameter allows you to control whether the CLR calls the hook function If you want to allow the hook call, set *pbHookFunction to TRUE If you set it to FALSE, the hook function isn't called If you want to change the value passed as the hook parameter, return that value from your FunctionIDMapper function I see FunctionIDMapper as being quite interesting for larger projects that use the Profiling API For example, you have to look up the function class and method name on nearly all calls into the hooking functions. To illustrate the differences between Jorgensen's robust formula and the 3(BC) formula, compare the two approaches using the Next Date program The extreme physical input values for the month, day, and year parameters are 1 and 12, 1 and 31, and 1582 and 3000, respectively Using Jorgensen's 6n + 1 formula for robust boundary testing, the number of boundary tests of input variables is (6 * 3) + 1, or the 19 tests listed in the BVA text matrix in Table 5-4. You could use the FunctionIDMapper function to handle the function lookup instead and pass the values onto the hook function That way you have a single place in which you're performing the lookups With the option to control whether the hook function is actually called, you have more power at your disposal For example, when you want to do logging or analysis for only a single thread, you can use FunctionIDMapper to determine the thread ID, and if you're not interested in watching the thread, you can skip the hook function The option to skip the hook function can make the design of your profiler much easier to implement In fact, I took advantage of it in the FlowTrace program.. No matter how many columns in a row have effectively been updated, in the <diffgr:before> section, the original row is stored in its entirety. The XML layout of the row depends on the column mappings, as shown here: <diffgr:before> <Employees diffgr:id="Employees2" msdata:rowOrder="1"> <employeeid>2</employeeid> <lastname>Fuller</lastname> <firstname>Andrew</firstname> </Employees> 369 vb.net pdf text extract How to Read PDF document in Vb . net ????? - MSDN - Microsoft
