In VBScript, the script interpreter does not handle any errors it finds, and runs the next statement using the on error resume next statement. Once the statement has been processed, the script engine will continue to run the subsequent program,

One-time Initialization Sometimes we need to initialize some POSIX variables only once, such as the thread key (as I will discuss below ). If we initialize the program multiple times, an error will occur. In traditional sequential programming,

I. Overview:Let's talk about why you should have a thread. As we all know, a process can only make one execution flow, although it is possible to create child processes, but the overhead of creating, terminating, switching between processes and

Threads: Threads are an execution flow in a program, each with its own proprietary registers (stack pointers, program counters, and so on), but the code area is shared, meaning that different threads can execute the same function.Multithreading:
