Programs store their data in main memory. On program exit, all this data is lost. Therefore, when you restart your program, all the fields (like your auto-increment number) will no longer hold their former values.
To fix this, you need to write the auto-increment number to disk, e.g. by storing it in a file. Then, on program start, you want to load the previously saved number back into main memory.

程序将其数据存储在主存储器中。程序退出时，所有这些数据都会丢失。因此，当您重新启动程序时，所有字段（例如自动递增数字）将不再保留其以前的值。
要解决此问题，您需要将自动递增数字写入磁盘，例如将其存储在文件中。然后，在程序启动时，您希望将先前保存的数字加载回主存储器。
