waiting thread object state changes. Access to a code snippet can be synchronized by locking and unlocking the specified object. Monitor.Enter, Monitor.TryEnter, and monitor.exit are used to lock and unlock the specified object. Once the lock of the specified object (code snippet) is fetched (called Monitor.Enter), no other thread can acquire the lock. For example, thread x obtains an object lock that can be freed (call Monitor.Exit (object) or monitor.wait). When this object lock is freed, the

How to control the relationship between multiple threads, without conflict and repetition, requires the use of mutually exclusive objects, namely: The Mutex class in the System.Threading namespace. We can think of a mutex as a taxi and a passenger as a thread. Passengers first wait for the bus, then get on the bus and finally get off. When a passenger is in the car, the other passengers can only get on when he gets off the bus. This is also true of the thread's relationship to the mutex object,

default Admin user account with a blank password when Access starts. In the background, Access uses the Admin account as the Administrator account for the workgroup. For all databases, tables, queries, forms, reports, and macros that you create, access also uses the Admin account in addition to the owner (group or user) of those objects. Administrators and owners are important because they have the right to be undone: Administrators (members of the Admins group) always have full permissions t

positioning of its own and possible descendant elements. In simple terms, this means that the element needs to be more costly to maintain itself and its contents, rather than relying on ancestral elements to do the work. Therefore, some elements will have a layout by default. When we say that an element "owns layout" or "gets layout", or that an element "has layout", we mean that its Microsoft proprietary attribute Haslayout is set to true. A "layo

} Therefore, the implementation of synchronization needs to consider all the necessary security to update multiple shared variables, there can be no race conditions, can not destroy the data (assuming the boundary of the synchronization is correct), and to ensure that other threads of correct synchronization can see the latest values of these variables. By defining a clear, cross-platform memory model (which is modified in JDK 5.0 to correct some of the errors in the original definition),

thread does not own the window or owns any windows. So why call the Setfoucs function to have this requirement? This can only be said I am not very clear, but in conjunction with "Windows core programming" in the 26th chapter of the relevant description, each thread has its own keyboard focus, should be to some extent answer this question. This situation is mentioned in the article "main interface security in multithreaded programming," which is

Shared_ptr can also be securely placed in the standard container and make up for the defects that STD: auto_ptr and qscopedpointer cannot use pointers as container elements because of the transfer semantics.Qweakpointer and STD: weak_ptr Qsharedpointer of the strong reference type is already very useful. Why do we need qweakpointer of the weak reference type? Qweakpointer is a smart pointer introduced in combination with qsharedpointer. It is more like a helper of qsharedpoint

The mutex class in the system. Threading namespace is used to control the connections between multiple threads without conflict or repetition. We can regard mutex as a taxi and passengers as a thread. The passenger first waits for the car, then gets on the bus, and finally gets off the bus. When a passenger is in the car, other passengers can get on the car only after they get off the bus. This is also the relationship between the thread and the mutex object. The thread uses mutex. the waitone (
