Traverse Records in a data readerWhen the ExecuteReader method returns a DataReader object, the position of the current cursor precedes the first record .The Read method of the reader must be called to move the cursor to the first record, and then the first record becomes the current record.If the data reader contains more than one record, the Read method returns a Boolean value of true.To move to the next

Reader domain: If you want to restrict access to a specific document created by a form, add a "Reader" field to the form. The "Reader" field clearly lists users who can read the documents created in this form. For example, if you restrict the personnel files of an employee to only members of the "Human Resources" department, the employee himself or herself, and t

Philosophers dining problems are very useful in modeling processes such as competition for mutually exclusive access to limited resources (such as I/O devices. Another famous issue is the reader-writer issue (Courtois ).Et al., 1971). It creates a model for database access. For example, imagine an airplane ticket booking system in which many competing processes attempt to read and write data. Multiple processes can read the database at the same timeBu

If you only want to read data without updating the data, you do not have to store it in the dataset. On the contrary, data can be read directly from the database and the application can be read.In this case, you can use a data reader to simplify the code. If the program needs to perform continuous read-only transfer through the query results, you can use the data reader object instead of filling the dataset

requirements to meet the time of production, which for critical resources access will produce a certain sequence, Will increase the read speed of resources within the system. consumers point to a location where there are valid data, the producer points to the location is not valid data, and the pipe ring buffer similar to the pipe of the ring buffer to take a look at understanding it. in this picture, you can think of write as a producer, in the production of data, read can be seen as a consume

Reader-writer problem (Readers-writers problem) is also a classic concurrent programming problem, which is often a synchronization problem. Data (Files, records) in a computer system are often shared by multiple processes, but some of these processes may require only read data (called Reader readers), while others require the modification of data (called writer writers). In terms of shared data,

Reader writer is also a very well-known synchronization problem.The reader writer's question description is very simple, there is a writer many readers, multiple readers can read the file at the same time, but the writer does not allow readers to write the file, the reader is also reading the file when the writer does not go to write files.#pragmaOnce#define_crtd

XmlTextReader from the URL myXmlURLreader = new XmlTextReader (URLString) C # VB After loading, the sample code calls the formatxml function. In this function, xmltextreader uses the read method to move XML data and read data in order to obtain the next node. If no node exists, this function returns false. For more information about the operating principles of the read method, see how to read XML from a file while (reader.Read())

1. Reset response (answer to request) The reader calls a card in the magnetic field to respond to the call. For cards that have just entered the magnetic field and obtained an electrical reset in the idle state, the card Request (reqa, 0x26); for cards that have been read and written and enter the sleep state, wake-up (wake-up, 0x52 ). In this solution, the card Request (reqa) can only call cards in the idle state. WAF can call all cards, including t
