When we use winform applications, we usually encounter the problem of using the control information on the multi-threaded control interface. However, we cannot use traditional methods to solve this problem. I will introduce it in detail below. First,

Multi-threaded case-timer In this case, after the screen starts, enter the interface as shown in the figure. There is a text box on the screen to show the elapsed time, in addition to a "Stop Timer" button. The use case diagram of the case is shown

In fact, if the threads are independent and do not involve any resource access, these non-interfering threads will not cause any problems. However, in practical applications, our threads always involve resource access, and often involve access to

Object Search-Indexes and instancesFirst, index and instance description:1) Index: number in the same level, number of the component in the sibling class, index starting from 02) Instance: number of the same class of components in the same layout,

Synchronized, as its name implies, represents thread synchronization. So how to use it in Java programming? Let's first look at this situation: For the same variable syndemo, we call syndemo. synmethord1 () and syndemo. synmethord2 () in two
