Most applications benefit seamlessly from all the Windows Vista improvements Most customers using those applications are thrilled by the improvements and are eager to upgrade all computers to Windows Vista However, some applications crash at random intervals when started under Windows Vista, and the customer demands a new version The vendor must investigate the root cause of the problem, find a solution, and provide a Vista upgrade for his application On previous versions of Windows, crash investigations could be completed in a reasonable time On Windows Vista, it can take considerably longer Why is that so Although most applications run great in the new environment, Windows Vista security and reliability enhancements affect their functionality The system is more robust at the expense of applications compatibility The Windows Vista operating system is less tolerant of application memory failures and enforces higher security restrictions on system resources Several familiar system mechanisms redesigned for Windows Vista require some ramp-up time This chapter walks through all the scenarios described in the book scenarios that we consider commonly used in debugging Windows applications with the goal of discovering what is different in Windows Vista The intent of this chapter is not to be a compressive list of Vista changes; it is limited to the changes with direct implications in the debugging process The following sections, each corresponding to a previous chapter, follow the same sequence as the book chapters Each subheading loosely follows the corresponding chapter organization and focuses only on differences from the previous operating system versions s not represented here present no significant differences from Windows XP Service Pack 2, and you can assume that nothing specific has been changed However, it is possible to see slightly different behaviors caused by security improvements This chapter reuses several samples introduced in the previous chapters The binary files targeted to Windows Vista x64 are available in the C:\AWDBIN\ WinLHAMD64chk folder The binary files targeted to Windows XP are available in the C AWDBIN\WinXPx86chk folder. vb.net barcode scanner source code Reading Barcodes in C# & VB.Net Tutorial | Iron Barcode

My CodeBank Submissions: TETRIS using VB. We think it's inevitable that every SQL DBMS will support bitmap indexes soon, so we're sure that the following tips will be handy Remember that B-trees are considered effective by optimizers if selectivity is greater than 01 If your queries use "key values" with lower selectivity than 01, the best way to speed them up is with bitmap indexes B-trees and bitmap indexes do not combine well When you search via a B-tree, you get a list of ROWIDs n index-key order When you search via a bitmap, you get a list of bits in ROWID order Because the lists differ in structure, ANDs, ORs, and NOTs require extra conversion steps Assembly-language instructions for AND, OR, and NOT all take only two cycles for each 32-bit word in a bit vector However, no fast assembly-language instruction tells you "how many bits are on in the word" or "which bit is on in the word" Therefore a DBMS is fast at Boolean logic but relatively slow at finding particular rows Bitmap indexes are particularly useful for queries that contain [NOT] EXISTS, UNIQUE, or GROUP BY Bitmap indexes are occasionally used for joins, but that's part of an internal process that the application programmer can't influence Bitmap indexes are particularly useless when a column can be any one of thousands of possibilities Have you ever noticed that "income" reports or questionnaires contain no gross averages or individual figures but only boxes (eg, [] 1500-3000 [] 3001-6000 [] more) That kind of pregrouping is a big aid for bitmap index construction A common recommendation is that a column is a candidate for a bitmap if the number of possible distinct values is less than 1% of the total number of rows For example, if the column is color and the value can be any one of the values in a 256-color display or NULL, the number of rows in the table should be at least 25,700 before you put color in a bitmap index Bitmap indexes are best for large (because a bit of storage is efficient), non-normalized (because there will be many repetitions), static (because updating one row means updating multiple bit vectors) tables.
