. NET. This software factory allows you to create modules associated with sub-directories in the site, in a pattern (such as view-presenter and application Controller) provides a framework that supports independent website development, testing, and deployment in a modular manner. It is worth studying carefully. Subsequent articles will detail the composite Web application blocks and the view-presenter mode.Attachment:/files/terrylee/compositeweb.rar Author: terryleeSource: http://terrylee.cnblo

the chips were computed by their mobile processes in the circuit. Although it is an early product, at least now we know that the concept is feasible, and living computers can become an important component of future supercomputers-perhaps even with traditional silicon-based machines.Nicolau said: "Now this model can successfully deal with a single problem, there will be more peers to promote the development of this area, such as the use of different biological media." It's hard to say when we ca

.[Uiofdsaouishj, ISLGBT] is a two-name non-canonical property that I intentionally wrote. Presumably after guessing the name of the property, Initwithcoder the method again and get the TestInfo clear text.The above tests were done because of doubts about the Nsuserdefaults's preservation of the data. It is proved that the nsuserdefaults data preservation is poor, and before using encodeobject, it needs to encrypt with its own encryption algorithm, even if the class is analyzed, the plaintex

In and Existsin is the appearance and the inner table as a hash connection, and exists is the external loop loop, each loop loop and then query the internal table. The assertion that exists is more efficient than in is inaccurate. If the two table size of the query is equal, then the in and exists are not very different. If one of the two tables is smaller, one is a large table, then the subquery table is large with exists, and the subquery table is small in: For example: Table A (small table),
