This code is far from complete, but I thought that it would help some VB programmer out there as the other ... To set your exception filter function, simply call SetCrashHandlerFilter. Internally, SetCrashHandlerFilter saves your exception filter function to a static variable and calls SetUnhandledExceptionFilter to set the real exception filter, CrashHandlerExceptionFilter. If you don't add any modules that limit the exception filtering, CrashHandlerExceptionFilter will always call your exception handler no matter which module had the hard crash. Calling your exception handler when no modules are added was by design so that you'd have to use only one API call to set your final exception handling. It's best if you call SetCrashHandlerFilter as soon as you can and make sure that you call it again with NULL right before you unload so that you allow my crash handler code to remove your filter function. Figure 13-1 shows a diagram of how a crash handler works. vb.net read pdf file itextsharp: VB .

WHERE employeeid=@empID FOR XML AUTO The final XML output takes the following form: <employees firstname=".." lastname=".." title=".." hiredate=".." /> As you can see, the class requires some attribute overrides to adapt to the actual XML stream coming from SQL Server In general, you can modify either the SQL command or the class source to make each fit the other's structure This is not always possible, however When it's not possible, attribute overrides are the only safe way to make two immutable and incompatible flows of data interoperate Overriding the Class Name In this scenario, the serializer is used only to deserialize data coming from SQL Server No previous serialization has been explicitly done The deserializer reads the inbound data and determines an ad hoc class structure It then matches this inferred structure with the specified type to be deserialized to in this case, Employee. vb.net read pdf into byte array: C# / VB .

It is important to remember that block testing is generally sufficient for unit testing purposes, but it is a relatively weak form of structural testing However, there are a few programmatic structures for which testers might need to design block tests to ensure adequate structural coverage of a function One type of structure where block testing is appropriate is the switch/case statement A switch statement is an effective method to handle control flow through a function that involves multiple choices or selections for a parameter When we step through a switch/case statement in the debugger, we can see control flow transfer immediately to the case statement that matches the parameter passed to the switch statement For example, programmatic platform profiling is quite common in automated tests when the procedures or outcome might be different depending on the specific Microsoft Windows operating system version. itextsharp read pdf line by line vb.net PDF to Text - CodeProject

Figure 13-1: Diagram of a crash handler AddCrashHandlerLimitModule is where you add a module to limit the crash handling All you need to pass to this function is the HMODULE for the module in question If you have multiple modules that you want to limit crash handling to, just call AddCrashHandlerLimitModule for each one The array of module handles is allocated from the main process heap As you look at the various functions in Listing 13-4, you'll notice that I don't make any C runtime library calls Because the crash handler routines are called only in extraordinary situations, I can't rely on the run time being in a stable state To clean up any memory that I allocated, I use an automatic static class whose destructor is called when BUGSLAYERUTILDLL is unloaded. The first issue to consider is the name of the class The deserializer takes the class name from the root of the stream In our example, the inferred class name would be employees This issue is easily resolved by creating an alias for the SQL Server table Add an AS Employee clause to the table name, and you're done As mentioned, however, this solution is not possible at all if you don't have enough rights to modify hard-coded SQL code An XmlRoot attribute is another way to work around the problem The attribute can be assigned either statically or dynamically Again, static attributes require that you have access to the class source code Let's create attributes dynamically, as follows: XmlAttributes changesRoot = new XmlAttributes(); XmlRootAttribute newRoot = new XmlRootAttribute(); newRootElementName = "employees"; changesRoot. I also provide a couple of functions that allow you to get the size of the limit module array and a copy of the array GetLimitModuleCount and GetLimitModulesArray I'll leave it up to you to write a RemoveCrashHandlerLimitModule function One interesting aspect of the implementation in CRASHHANDLERCPP is how I handle initializing the DBGHELPDLL symbol engine Because the crash handler code can be called at any time, I needed a way to get all the process's modules loaded at the time of the crash SymInitialize will take care of this automatically for you by setting its third parameter, fInvadeProcess, to TRUE Another interesting aspect to the code is the way I deal with ANSI characters in a Unicode world. A function similar to the SimpleGetNT5ClientVersion function can help us determine whether the program or automated test is running on a Windows 2000-based or a Windows XP-based client The sequential control flow diagrams (CFDs) in Figure 6-5 illustrate control flow through the SimpleGetNT5ClientVersion function for a non-NT5 kernel operating system, a Windows Server 2003 operating system, and the Windows 2000 Server and Windows XP operating systems, respectively.. Since the CrashHandler code, which I provided in the first edition of this book, has proven extremely popular and countless products are using it, I had to balance the needs of developers who will want to drop the new CRASHHANDLERCPP into their existing projects Consequently, I didn't feel comfortable relying on my large symbol engine wrapper SYMBOLENGINELIB to handle the character conversions because it would prevent direct upgrades I finally settled on using wsprintf to do many of the translations by specifying 500. XmlRoot = newRoot; You create an XmlRootAttribute object and set its ElementName property to the name of the source root tag in this case, employees Next you assign the newly created element attribute to the XmlRoot property of the XmlAttributes object that gathers all the attribute overrides for a particular element in this case, the class as a whole To become effective, the changes must be added to an XmlAttributeOverrides object, which will then be passed to the type-specific serializer's constructor, as shown here: XmlAttributeOverrides over = new XmlAttributeOverrides(); overAdd(typeof(Employee), changesRoot); Overriding Class Properties Each property of the Employee class must be renamed and remapped to match one of the source XML attributes because we assume we're working on the data flow of a FOR XML AUTO, in which each field is rendered as an attribute. %S formatting, which indicates an ANSI character string is a parameter when compiling for full Unicode. For those spots in which I needed to do the conversions myself, I decided to use the _alloca function to allocate the memory off the stack instead of using the C run time or operating system heaps because the heaps might be corrupted and be the reason for the crash. If the crash was caused by a stack overflow, because there's so little room on the stack, any code I executed would probably cause a double fault long before the code hit one of the _alloca calls. Figure 6-5: Sequential control flow diagrams for GetOSVersion function. SimpleGetNT5ClientVersion Function Translating EXCEPTION_POINTERS Structures Now that you've written your exception handlers and crash handlers, it's time to talk about those EXCEPTION_POINTERS structures that each is passed Because these structures are where all the interesting information about the crash is stored, I wanted to develop a set of functions that you can call to translate the information into human-readable form With these functions, all you need to concentrate on is the display of information to the user in a manner that's appropriate for your particular application You can find all these functions in Listing 13-4 I tried to keep the functions as simple as possible All you need to do is to pass in the EXCEPTION_POINTERS structures. No remapping would be needed if you assumed the data flow of a FOR XML AUTO ELEMENTS, in which fields are represented with elements Renaming properties is necessary because the deserializer works in a strictly casesensitive fashion and considers firstname completely different from FirstName, as you can see by running the following code: 413. Each function returns a pointer to a global string that holds the text, which allows me to write the code so that it doesn't rely on any heap memory and so that the big buffers it needs are always present Some of you might look at the code and cringe because it uses global variables and recycles buffers, but it's the safest code I could possibly write The GetRegisterString function simply returns the formatted register string The GetFaultReason function is a little more interesting in that it returns a complete description of the problem The returned string shows the process, the reason for the exception, the module that caused the exception, the address of the exception, and if symbol information is available the function, source file, and line number where the crash occurred CrashHandlerTestexe caused an EXCEPTION_ACCESS_VIOLATION in module CrashHandlerTestexe at 001B:004011D1, Baz()+0088 byte(s), d:\dev\booktwo\disk\bugslayerutil\tests\crashhandler\crashhandler. vb.net read pdf to text NET PDF Text Extractor & Converter - Extract Text from PDF C#/ VB ...
