The concept of code reuse (reusing sections of code or components) has always been a topic in software engineering. A software library, such as the common dialog library shipped with Windows, is a good example of code reuse. This library (comdlg32.dll) contains all of the dialog boxes and related functions used for opening and saving files, printing, choosing colors, and other common user interaction tasks. Programmers don't need to write their own functions or create their own UI to open or save files; they can just use the functions in the common dialog library. Several years ago, when Office made the shift from being merely a group of applications geared toward people who needed spreadsheet and word processing functionality to a unified suite of applications for the business user, the team discovered that many functions were duplicated across the different applications. Because of this, mso.dll, the shared Office library, was born. With the shared library, programmers on the Office team can easily access common functions and implement consistent functionality and user interface across applications. A bigger benefit is that the test team needs to test these functions only in one place everyone benefits. Shared libraries work well in Windows and Office mainly because they are development platforms; that is, they are designed with the intent that programmers will use the exposed functionality to add to or enhance the baseline platform architecture. Code reuse also works well in Office because it's one product line. The challenge in taking better advantage of code reuse in tools and utilities is that most divisions or product lines have their own solution developed without knowledge of the other solutions. For the most part, there's no motivation and little benefit to share code. vb.net pdf print library: How to Print a PDF programmatically without the... | Adobe ... read pdf file using itextsharp vb.net How to Read PDF document in Vb . net ????? - MSDN - Microsoft

Common Assembly-Language Constructs Up to this point, I've just been covering basic assembly-language instructions Now I want to start looking at various assembly-language constructs that you'll encounter and explain how you identify them and translate them into higher-level operations FS Register Access In Win32 operating systems, the FS register is special because the pointer to the thread information block (TIB) is stored in it The TIB is also called the thread environment block (TEB) The TIB holds all the thread-specific data so that the operating system can keep your thread access straight This thread-specific data includes all the structured exception handling (SEH) chains, thread local storage, the thread stack, and other information needed internally For more information about SEH, see 13 For an example of thread local storage, see the MemStress discussion in 17. On many levels, there is no problem. There are far worse problems a company can have than having too many lightweight XML parsers in the library. Additionally, the tools are shared in a central repository where everyone in the company can search for utilities and download whatever is appealing to them. More choices should lead to a better selection for everyone, but the opposite is generally true. In The Paradox of Choice, [3] Barry Schwartz discusses how having too many options to consider makes the ultimate decision much more difficult; that is part of the problem, but there's more to it. One of the great things about Microsoft is that every product group sets their own goals, their own vision, and they determine their own way to solve the engineering problems they face from day to day. There's not much motivation other than saving time to adopt or reuse code for tools and utilities. </lastname> </TableName> </DataSetName> Tip You can get the string representing the XML version of the DataSet object through the DataSet method GetXml The text does not include schema information You can get the schema script separately by calling the GetXmlSchema method To persist the XML representation to a stream, use the WriteXml method instead.. The TIB is stored in a special memory segment, and when the operating system needs to access the TIB, it converts the FS register plus an offset into a normal linear address When you see an instruction accessing the FS register, one of the following operations is underway: an SEH frame is being created or destroyed, the TIB is being accessed, or thread local storage is being accessed Creating or Destroying an SEH Frame The first instructions after setting up the stack frame are often something like the following code, which is standard code to start a __try block The first node in the chain of SEH handlers is at offset 0 in the TIB In the following disassembly, the compiler is pushing a data value and a pointer to a function on the stack That function is __except_handler3 in Windows 2000 code. In Windows XP operating system code, the special function is _SEH_prolog The first MOV instruction is accessing the TIB; the offset of 0 indicates that a node is being added to the top of the exception chain The last two instructions indicate where the code moves the actual node to the chain PUSH 004060d0 PUSH 004014a0 MOV MOV EAX , FS:[00000000] DWORD PTR FS:[0] , ESP PUSH EAX. Transforming the DataSet Object Transforming a DataSet object into a Recordset object poses a couple of problems. The first is that you have to infer and write the Recordset object's schema. The second is that the XML layout of the DataSet object depends on a number of different parameters. In particular, the root of the XML version of the DataSet object depends on 267 But still, there is a prevalent worry that code reuse isn't used as much as it should be, and that duplication of efforts and the not-invented-here (NIH) syndrome are prime targets as areas of improvement. To make tool adoption work across groups in a company the size of Microsoft, it is not enough to share just the tool the code needs to be shared as well. Although this example is nice and clean, the compiler doesn't always produce such tidy code. Sometimes it spreads the SEH frame creation throughout the code. Depending on the code generation and optimization flags, the compiler moves instructions around to take better advantage of the CPU's pipelining. The following disassembly example, in which KERNEL32.DLL symbols are loaded, shows the start of the Microsoft Windows 2000 IsBadReadPtr function: PUSH EBP MOV EBP , ESP PUSH 0FFFFFFFFh PUSH 77E86F40h PUSH OFFSET __except_handler3 MOV MOV EAX , DWORD PTR FS:[00000000h] DWORD PTR FS:[0] , ESP 302 PUSH EAX the object's DataSetName property. Likewise, each table record is grouped under a node whose name matches the DataTable object's TableName property. You could easily work around the first issue by writing a more generic XSLT script. As for the second problem, because a DataSet object can contain multiple tables, you must necessarily know the name of the table you want to process and render as a Recordset object. The name of the table must be passed to the XSLT processor through the argument list. The following code shows how to transform the DataSet object into an XPath document and load it into the processor. The result of the transformation is directly written out to an auto-indent XML writer. The argument passed to the style sheet is the name of the first table in the specified DataSet object. // Set up the style sheet XslTransform xslt = new XslTransform(); xslt.Load("ado.xsl"); // Create an XPath document from the DataSet XmlDataDocument doc = new XmlDataDocument(data); // Prepare the output writer XmlTextWriter writer = new XmlTextWriter(outputFile, null); writer.Formatting = Formatting.Indented; // Set some arguments XsltArgumentList args = new XsltArgumentList(); args.AddParam("TableName", "", data.Tables[0].TableName); // Call the transfomer and close the writer upon completion xslt.Transform(doc, args, writer); writer.Close(); The XmlDataDocument class internally creates an XML DOM representation of the DataSet content. That content then becomes the input for the XSLT style sheet. The ADO Style Sheet Let's analyze the XSLT code necessary to transform a DataSet object into the XML version of an ADO Recordset object. The following listing shows the over-all layout: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" /> <!-- Matches the DataSet's root, whatever the name --> <xsl:template match="/child::*[position()=1]"> <!-- PARAM:: Name of the table to consider --> <xsl:param name="TableName" select="string('Table')" /> 268 vb.net pdfreader How to read PDF file in C#, VB .
