operation can continue to perform other tasks. When the operation is complete, his callback function is notified so that the program knows that the operation has ended NET4.5 already supports async and await, making async as easy as synchronizing programming. The purpose of the await keyword is to start a task that will be executed (the task will be executed in the new thread) and return immediately so that the function in which the await is located

Origin: In the old boy Linux training shell programming teaching, found a lot of good level of friends and classmates are still very confused, the following for everyone to share the use of the array of small examples, I hope to give you a little help. In fact, the shell array is very simple and useful. We should follow the principles of simplicity and ease of use in our study.Simple usage and

Analysis of javascript functional programming examples This article mainly introduces javascript functional programming. The example analyzes the usage skills related to javascript functional programming, which is very useful. For more information, see This example describes javascript functional

Origin: in the shell programming teaching conducted by old boys in Linux training, many well-experienced netizens and students are still confused about arrays. The following is a small example of array usage, hope to help you. In fact, the shell array is very simple and easy to use. We should all follow the simple and easy-to-use principle in learning. Simple array usage and examples in shell

Using examples to fully explain the use of the relevant functions of multi-process programming in PHP, PHP functions PHP has a set of process control functions (which require –enable-pcntl and POSIX extensions at compile time), enabling PHP to create sub-processes like C, execute programs using the EXEC function, and process signals. Use PHP real multi-process operation mode, suitable for data collection,

Functional programming is the use of a series of functions to solve the problem, according to the general programming thinking, the face of the problem we think the way is "how to", and functional functional programming thinking is what I want to "do." As for the features of functional programming are not summarized, w

Programming a few days ago on the internet under the "Flash MX practical Programming Hundred cases", open the source code looked at, the total feeling of the example is OK, but the code is too old, some or Flash 4 format, and then want to adapt the code, one is a learning, two will take the opportunity to have their own knowledge to comb. a few examples of Flas

After studying Android for half a year, books in the library have almost been borrowed. The final conclusion is that only the typical Android programming examples and project development book is the best. The author is published by Wu Yafeng, du huamei, Su yaguang, and the Electronic Industry Publishing House. Where is this book ?? Let's talk about other books in two ways. One is the implementation of an ex

block of local memory of 12 bytes in size, and the first address is expressed in buffer.The code is clear, first reading the CPUID to the EBX,EDX,ECX register, and then using the EDI Register as an index, stitching the read string into buffer, then invoking printf with output and buffer respectively, equivalent to calling printf (" The CPU ID is '%s ' \ n ', buffer) to print, and finally call exit (0) to return.10. Concluding remarksAs described in this article, you should know how to design a
