Yesterday because the project needs to access the system Address Book to get the phone number, so from the ignorance, began to Daoteng, Daoteng an afternoon, finally finished. Write this blog is to record, the next time you do not make a mistake. At the same time, I have the same rookie can avoid a detour.Well, to get started, to access the system's address book,

included with SQL ServerDatabase Not supported The resource database is located in the Mssqlsystemresource.mdf file,The file contains nearly the code. Therefore, SQL Server cannot back up the resource database.However, it can be done through file backup and backup to disk, and not through SQL Server when restoring.To restore these backups, you can only manually restore the backup copy of Mssqlsystemresource.mdf.And be careful not to overwrite the current resource database with a

Linux depth Introduction First, from the introduction of Linux system installation, the Linux system management and server configuration of the two parts of knowledge.

. From here, the CPU is a series of operations that can be used to process processes.The creation of processes, the destruction of the state of communication between transitions between synchronous asynchronous concurrency and the scheduling of processes. The details are as follows:3.2 Memory 内存的主要作用就是给cpu提供数据，既然是内存那就避免不免的流程： 分配 回收 我们所有的操作也都时围绕这俩点进行的，说道内存的分配那就肯定分为俩中情况： 连续 非连续 类似于数据结构 的线性和非线性。 连续分配内存就是很简单了，就是分配连续的内存，但是分配多少呢，这就是一个问题了，所以就分为固定内存的分配 和动态内存的分配（根据程序，数据 大小），并且采用相关的分配算法。缺点：内存碎片化

-sharing operating systems and RTOs were also designed in the 60 's. In the 70 's, the microcomputer operation system was designed on the basis of batch processing system, and the network operating system was designed on the basis of time-sharing operating system. By the 80 's, the distributed operating

In many cases, we have to use the operations of selecting contacts. It is very troublesome to write it by ourselves. Instead, it is better to directly call the system's address book. Let's look at the requirements below: Requirements:When an edittext button is clicked, go to the system address book. Select one address
