Without this capability, you couldn't even come close to getting accurate timings that related to anything in the user's application Microsoft has built this function-call notification right into the Profiling API yet another instance where they deserve great credit for doing the heavy lifting Now tool developers can concentrate on solving hard profiling problems without having to spend six months or more developing just the infrastructure Requesting Enter and Leave Notifications With the Profiling API, you'll get notified whenever a method is called and whenever that method returns The /Gh and /GH switches (which enable the _penter and _pexit hook functions, respectively) in the native C++ compiler follow the same basic strategy as the Profiling API, but the Profiling API makes notifications even easier by also handing you the FunctionID of the executing function. vb.net read pdf file itextsharp: How to Read PDF and Convert to Stream in C#/ VB vb.net read pdf file itextsharp Manipulating PDF files with iTextSharp and VB .

As with any of the other notifications, you first have to tell the run time that you'd like the notifications by ORing in the flag COR_PRF_MONITOR_ENTERLEAVE to the ICorProfilerInfo::SetEventMask method I would have bet that once you ask for enter and leave notifications, the notifications would be immutable for the life of the process However, the smart folks at Microsoft allow you to set and unset the enter and leave notifications as much as you want Keep that in mind, because you could create some very interesting tools with this capability, for example, one that times only exception processing After setting the options, you need to tell the run time which functions you want called, so you'll call ICorProfilerInfo::SetEnterLeaveFunctionHooks The three parameters are pointers to the functions you want called: the entry function, exit function, 426. vb.net read pdf line by line: Get/Retrieve/Extract PDF Form Fields VB .

NET Barcode Reading and Recognition. No Star. (0). If no match is found, ReadXml deduces that the row in the <diffgr:before> section was deleted from the table when it was at the position that the msdata:rowOrder attribute indicates. The method inserts a new row in the table at the same position and populates it with the values read from the <diffgr:before> section. Next the row is marked for deletion using the Delete method of the DataRow object. The final step consists of reading the values from the <diffgr:errors> section and updating accordingly the RowError property of the corresponding DataRow object in the table. The Row Commit Model The DataSet, DataTable, and DataRow objects maintain a local cache of changes. When a row is modified, deleted, or added, its state changes to one of the values of the DataRowState enumeration. (See the .NET Framework documentation for details.) Similarly, when a row is added, modified, or deleted from a table, the internal state of the table is altered, resulting in pending changes for the affected rows. Pending changes can be either accepted or rejected at the DataSet, DataTable, or DataRow level. Accepting a pending change means that the row (changes always involve a row) updates are committed to the table. Rejecting a pending change rolls back the state of the table, and the table appears as though the change never occurred. A DiffGram can track pending changes that is, in-memory changes that have not yet been committed. Table 10-3 lists the allowable states for a DataRow object. itextsharp read pdf fields vb.net How to read and extract data from pdf file in vb | The ASP. NET Forums

This code is far from complete, but I thought that it would help some VB programmer out there as the other ... The text box properties for the Year text box control are predefined to allow the user to input only four characters The second type of a boundary value is a fixed-variable boundary represented by a measurement that can be changed but that is constant at some point in time For example, the height and width of a window can vary in size along the x-and y-axes; however, at any given moment in time they are constant linear values that can be measured in pixels, millimeters, or inches Fixed-variable boundary values can be harder to identify because the linear measures might not be readily visible from the user interface Figure 5-3 illustrates fixed-variable boundaries for the height and width attributes of the canvas size in Microsoft Paint.. and tailcall exit function The first two functions are self-explanatory, but the third is a little weird In the current version of the common language runtime (CLR), the tailcall exit function is never called A tailcall is when the current method's stack frame is removed before the actual call instruction is executed In other words, the stack gets cleaned up before the method executes because nothing on the stack is needed Future versions of the CLR will utilize the tailcall compiler optimization, so you'll need it Since for most Profile API users, the tailcall exit function performs the same thing as exiting the function, you can simply use your regular exit function if you'd like Implementing the Hook Functions The special part of the function hooking process is defining your actual hook functions. To keep performance as fast as possible, the Profiling API requires that you write the functions using the naked calling convention In essence, your function is inlined right inside the Just In Time (JIT) compiler, so you have to handle the function prolog and epilog needs The typedef for any of the hook functions is as follows: typedef void FunctionEnter ( FunctionID funcID ) ; However, what's not too clear from the documentation but fortunately is shown in the profiling samples is that the hook functions are like standard calls in that they are responsible for popping the FunctionID parameter off the stack The comments in CorProfIDL, whose word you should always take over ProfilingDOC, mention that your hook functions are also required to save any registers your code will touch, including any floating-point registers. Table 10-3: States of a DataRow Object State Description The row has been added to the table, but AcceptChanges Added has not yet been called. Deleted The row is marked for deletion from the parent table. Detached Modified Unchanged Either the row has been created but not yet added to the table, or the row has been removed from the rows collection. Some columns within the row have been changed. No changes have been made since the last call to AcceptChanges. This is also the state of all rows when the table is first created. Figure 5-3: Width and Height variables, examples of fixed-variable boundaries that can be changed by the user at run time. Listing 11-1 shows you my enter hook function, so you can see one in action The hook functions use the naked calling convention, so you're required to write your own prolog and epilog CFlowTrace::FuncEnter is where the real work is being done, so the hook function is really just a wrapper to call it The prolog (the first three PUSH instructions) preserves the registers that are modified by this function The last four instructions are the epilog, which restores the saved registers and returns RET 4 returns and clears the function ID passed to the enter hook function off the stack, saving me a POP instruction Listing 11-1: Hook function example void __declspec ( naked ) NakedEnter ( FunctionID /*funcID*/ ) { __asm { PUSH EAX registers PUSH ECX PUSH EDX PUSH [ESP + 10h] the // MOV on the 427 ECX , g_pFlowTrace parameter. The AcceptChanges method has the power to commit all the changes and accept the current values as the new original values of the table, clearing pending changes. RejectChanges rolls back all the pending changes. We'll encounter the row commit model again in the section "A Save-And-Resume Application," on page 464, when we look at save-and-resume applications. The Original Data Section The DiffGram has a layered structure in which current values, original values for the modified rows, and pending errors are stored in distinct sections. The state of the DataSet object is rebuilt by combining the contents of these sections. The original values are stored in the <diffgr:before> section as a change with respect to the current data instance. The DataRow object maintains several versions of itself that are internally stored in an array of rows. The versions are grouped in the DataRowVersion enumeration, shown in Table 10-4. // Push the instance data // Push the function ID as // Save off whacked. Paul Jorgensen [6] suggests that the number of tests for basic boundary value analysis can be calculated by using the formula 4n + 1 (or 6n + 1 including the minimum -1 and maximum +1 values for robust boundary testing), where n is equal to the number of independent parameters. Jorgensen's formula includes a test for a nominal value. Although this formula is useful in analyzing the values at the RET 4 function // was // function. } } Table 10-4: Values for the DataRowVersion Enumeration Value Description Current Contains the current values of the row Default Original Proposed The default row version, according to the current state of the row Contains the original values for the row that is, the values stored when AcceptChanges was last called Contains proposed values for the row The middle four instructions call CFlowTrace::FuncEnter, passing it the class instance and the function ID The function ID was passed to the enter hook function It's now 16 (0x10) bytes up the stack, before the three registers we saved and the return address PUSH [ESP + 10] pushes a copy onto the stack to pass to CFlowTrace::FuncEnter Eagle-eyed readers will note that the declaration of CFlowTrace::FuncEnter takes only a single parameter That's because C++ class methods always pass the instance pointer (or this pointer) as the first, hidden parameter I played around with the inline assembly language in the hook functions quite a bit to see whether I could get anything smaller, but what you see in Listing 11-1 is about as small as you can safely go Inlining One very important issue with the hooked function notifications is inlining. itextsharp read pdf fields vb.net How to Convert PDF to Text in .
