This article will discuss the multithreading mechanism in C # programming and solve the thread control and multi-thread communication issues through some examples. In order to save the tedious steps for creating a GUI and more clearly approach the essence of the thread, all the following programs are console programs and the final console of the program. readline () is used to stop the program midway through, so that you can see the output in the
other functions on your own.

MySQL allows you to specify multiple statements for execution in a single query string by specifying parameters for the link:
CopyCode The Code is as follows: // set when linking
Mysql_real_connect (..., client_multi_statements );
// Or
// Specify midway through
Mysql_set_server_option (MySQL, mysql_option_multi_statements_on); // MySQL is the connection name.
When using the multi-statement execution function, you must read the entire resault set; ot

Note: In rotatingfilehandler, dorolover () Exits midway through because of a Rename () error. As a result, the log file is not opened, and subsequent log messages fail because the log file is not opened. You can add a try in Rename () or do not use rotatingfilehandler. It is estimated that fileconfig () can be restored once after
recovery, and large-capacity log recovery. But what are the differences between the four backup methods and their respective functions? What are the conditions for these three types of recovery? Here, I will give you an analysis:
Backup:
1. Full backup: Backup content, including all data, file groups, or data files in the backup database. Applicable type: Full backup is the most common technology for small and medium-sized databases. disadvantage: This process is very time-consuming. Once back

Second: the main method.Backgroundworker. runworkerasync --The method of "starting" Asynchronous call has two reloads: runworkerasync () and runworkerasync (Object argument). The second overload provides a parameter for asynchronous call. (If multiple parameters need to be passed, use a class to pass them ). After this method is called, The dowork event is triggered

We often encounter this problem. We use Telnet/ssh to log on to a remote Linux server and run some time-consuming tasks. As a result, the task fails midway through due to network instability. After the command is submitted, how does one prevent the local terminal window/network disconnection? Here are some examples. You can select different methods for different scenarios to solve this problem.
