ado| Access | The interaction between the data ado.net application and the underlying data source is based on a dual architecture with a two-way channel. You can use individual provider-specific commands or batch update procedures to access the data source to read and write rows. In both cases, data access produces a fully bidirectional binding and involves a variety of different objects and methods. You can use command classes such as SqlCommand and

A batch file is a file with an extension. BAT consisting of one or more doscommands and executable commands. When a user uses the batch processing file name as a command, DOS will automatically execute the commands in the file in sequence. Batch files are created and executed multiple times at a time.
There is a special batch
What are the commands in the batch file?
For the time being, the commands in the batch file can be understood as the DOS command, and will be explained later. batch Processing, as its name implies, is a pile of things heap together for processing. in other words, you can write a DOS command to it and execute it in sequence. The effect is similar to that of
In short, batch processing is used to automatically execute multiple commands continuously.
Here is the simplest application: When the WPS software is started, it must be executed every time (> the previous content indicates the DOS prompt ):C:/> Cd WPSC:/WPS> spdosC:/WPS> pyC:/WPS> wbxC:/WPS> WPSIf you perform this operation before Using WPS every time, do you think it is very troublesome?

Second, batch files are simple programs that control the flow of commands by conditional statemen
Why do we need batch processing?
We don't always want to get the information we need right away, the batch allows us to start collecting information on an established process before the request is processed, such as a bank statement, which we can generate on a monthly basis and open a batch process before the user queries.
Sometimes it can make the b

A For command is a command that runs in the command line or batch for a series of objects to execute one or more commands cyclically in sequence. Combined with some programs in Windows Management, its processing capabilities are powerful, and its applications are flexible and convenient. However, the complexity of the help information is often daunting for beginners. Here, based on my learning and understanding, we will simplify its usage, and neglige
folder by moving the file or folder.Usage: MOVE a file [Folder] 1 file [Folder] 2For example, move c: \ *. exe d:This command can be used to move all files with the extension EXE under the C root folder to the D Drive.
Copy files or folders.Usage: XCOPY file [Folder] Name 1 [file [Folder] Name 2] [Option]
It has many options, for example,/S can copy files in the entire folder (including subfolders),/E specifies to include empty folders, /V indicates the correctness of the copied file after copy
