ISAPI is an acronym for Internet Server Application Programming Interface. ISAPI is a low-level interface that resides beneath higher-level abstractions like ASP.NET. In many ways, you can think of ASP.NET as a developerfriendly way of working with ISAPI. It s possible to work with ISAPI directly, but it s much easier if you can find an alternative approach! Every web development technology that s compatible with IIS must be able to communicate with ISAPI, which provides the ability to process page requests and send responses. An ISAPI extension, such as the ASP.NET ISAPI extension, is the go-between that can process and make sense of code written in a given programming language, and process it so that it s possible to send an appropriate response to the client browser. IIS has a list of allowed file extensions that it can handle, and each file extension maps to an ISAPI extension designed to handle that type of request. ASP.NET pages have the extension .aspx, and the ASP.NET ISAPI extension is aspnet_isapi.dll, which is located in the %WinDir%\Microsoft.NET\Framework\v1.1.4322 folder. When IIS receives a request, the file extension will tell IIS which extension to pass the request to for processing. This extension will then pass the request on to the ASP.NET worker process to be processed. The ASP.NET ISAPI extension passes requests for ASP.NET pages to aspnet_wp.exe (w3wp.exe in Windows Server 2003), which runs as a system process. Here, you can see this process highlighted in the list that s produced by the Windows Task Manager on a Windows 2000/XP machine: vb.net code 39 reader VB .

If the optimizer thinks the data in your table is well clustered, then the cost will be low, favoring the use of indexes If the optimizer thinks the data in the table is very scattered, then the cost will be higher, favoring the use of alternative execution plans (such as tablescans) Counterintuitively, the state of your table can have a much bigger impression on the optimizer s calculations than the state of the index itself Of course, if your data really is distributed the way the optimizer thinks it is, then the cost calculation will often come close to a realistic run-time use of resources, and you will think the optimizer has done a good job If the clustering_factor doesn t represent the real distribution, then the cost calculation will be wrong, and the optimizer is likely to choose an unsuitable execution plan.. data matrix code word placement, birt code 39, police word ean 128, eclipse birt qr code, birt pdf 417, print barcode in word 2007 vb.net code 39 reader read code 39 barcode with vb . net - Stack Overflow

NET Code 39 barcode Reader Control is an advanced developer-library for . NET class ... NET Code 39 barcode scanner can read barcode images using VB . You can often reduce the number of leaf_blocks (and, very occasionally, the blevel) of an index by rebuilding the index; but rebuilding an index has no effect on the clustering_factor. Rebuilding an index may make that index appear more desirable to the optimizer, but the side effects may be good or bad. On the plus side, rebuilding an index may introduce a caching benefit for that index at query time but the downside is a possible contention penalty on DML, combined with an increase in leaf blocks splits and redo generated as the index tries to get back to its equilibrium state. Counterintuitively, an index may end up needing regular rebuilds because you ve started to rebuild it regularly (see script rebuild_test.sql in the online code suite for an artificial example demonstrating the concept). If you want to get the optimizer to behave properly, it is usually more important to check whether or not the clustering_factor represents the real data scattering and do something about that, rather than simply wedging the index into a tighter hole. vb.net code 39 reader C# .

On a Windows Server 2003 machine, you would see a w3wp.exe process running with the NETWORK SERVICE account. On the first request for an .aspx page, this process is started automatically. (This is one reason why the first hit on an .aspx page can take so long.) Subsequent hits to the same page benefit not only from the fact that there is a cached, compiled version of the page stored on the server, but also from the fact that the ASP.NET process is already started. Note that there s also an entry in the list some lines below the aspnet_wp.exe, called inetinfo.exe. This is the name of the process that IIS runs as, and it will appear in the list whenever the web server is up and running. In some cases it is desirable to keep whole content of a given band in one piece and to prevent page breaks that split the band when it stretches beyond its initial specified height. To do this, use the isSplitAllowed flag, which is true by default. Let s take a look at some more general examples of costing. For example: How do you handle range-based tests (e.g., n2 between 1 and 3) How do you handle partial use of a multicolumn index What effects do in-lists have How special is an index full scan What does the optimizer do when you don t have to visit the table vb.net code 39 reader Visual Studio .
