Exception handling Enterprise Library exception handling blocks (Enterprise Library Exception handling block) provide all the basic code needed to handle exceptions, and now you can no longer write these repetitive exception handling code simply by using them in your program, To ensure consistent and efficient exception handling. In an ideal program world, all the code written is run correctly, but the reality is, no matter how carefully you write co

Generally in this case, I like to ask myself: "If the question is to Apple, what will he do?" Of course, we all know that Apple certainly knows how to do this, because at one level, Apple's documentation is a guide to how we use design patterns. So we need to look at the circumstances in which Apple uses delegate and block, and if we find out how Apple makes this choice, we can build rules that can help us make the same choices in our own code. To find out where Apple uses delegate is simple,

-driven, modular design Direct use of custom tags such as , binding events, etc. in templates Build projects automatically using ScratScrat can be installed in a continuous integration system to automatically build the project, but also has the ability to build by version. Personal view The framework proposed by building blocks to develop the module, and finally the way to build the system is very good, before I developed projects are u

The optimizer must determine how to access the data that your SQL requires. The next step in generating an execution plan is to use the optimizer to determine the best way to access the data when the expression and condition evaluation of the SQL statement is closed, and all query transformations that may help to build the execution plan more accurately are executed. In general, there are only two basic methods of data access: Full scan and Index scan, and full scan may be a full table scan

IOS 4 presented a million billion new API's by Apple's count, but for this post I am going to show a quick demo of the new assets library API where you can now get to users photos and videos with more access than ever before. thisNew API relies on the new programming device called blocks that has been introduced with IOS 4. blocks are used through extensions of the new API's as a kind of extended @ selector
