In the interface program, often need some data classes, interface elements through the binding and other ways to display the data, however, because the UI thread is not thread-safe, it is generally necessary to invoke the interface control via Invoke. For Data-bound bindinglist, however, The Listchang event cannot be responded to, resulting in controls such as the backend grid not updating Data. Waste a gre

wait for it to become a set state, and during the wait, the thread that called Waitfor is in a suspended state. In addition WAITFOR has a parameter for the timeout setting, if this parameter is 0, do not wait, immediately return to the status of the event, if it is infinite wireless wait for this, until the set state occurs, if a finite number, wait for the corresponding number of milliseconds to return the status of the eventwhen the event transitio

The members of a class are divided into two classes, static members (static member), and instance members (instance member). A static member belongs to a class and an instance member is an instance of an object, that is, a class.A brief discussion of whether static fields and static methods are used in a class is a thread-safe issue.We are aware that the call to static field and static method is called through the class. Static methods do not operate
