It is easy to take advantage of the encryption and other protection methods provided by the Access database itself, which will not be discussed in this article. In Access database, embedded a strong database operation language--visualbasic language, so you can use VisualBasic programming,

Drawing attention to sketch in the proces

In the software development process, sometimes it is necessary to control some programs can not run at the same time, that is, multiple programs mutually exclusive operation (also includes the prohibition of running multiple instances of the same program). To address this issue, we implemented a mutex operation between multiple programs using a memory-mapped file in Visual C + + 6.0. Before you talk about specific programming methods, let's take a lo

A transaction is a technique that ensures data uniqueness and consistency in a database, and for a database or a set of writes to ensure that an atomic operation is required to use transactions, the common form of Android usage transactions is as follows:Sqlitedatabase db = null, ... db.begintransaction (); try {db.settransactionsuccessful ();...} finally {db.endtransaction ();}So what's the operation of Db.begintransaction? Let's look at the source code of Sqlitedatabase:/***beginsatransactioni

need to wait for you to unlock first.The workaround is to set the shared lock on the read of the file. Multiple threads can read files at the same time. Do not clog each other. Then set the exclusive lock when you want to write to the file. Add an exclusive lock so that other threads cannot read or write at this time.Windows provides a shared/exclusive lock call

when two OutPuter objects are instantiated, the output methods of the two objects cannot be synchronized. At this time, the field can use this to represent this class. However, the output () method cannot be used to pass in the form parameter, because the synchronization function is lost when the input parameter is different.2. Mutual Exclusion of the entire MethodThe mutex of the entire method is to add the synchronized keyword before the method name, for example:public synchronized void outpu

Why is the row exclusive lock still unable to lock other processes to select the data row? Example: Table TMP, 10000 data records, with ID as the primary key. Run the following command in process 1 (spid = 55: Run the following command in process 2 (spid = 64: View lock information: We can see that the S lock of the second pair of ID = 10 in the process is not locked by the X lock in process 1. This seems to be in conflict with Microsoft
