我不明白您的问题.如果列表框中有东西，它就会以某种方式到达那里，所以只要运行一下，程序就会再次加载它.如果您谈论的是选定的项目，只需将它们保存到文件中，然后在加载程序时，从该数据文件的内容中设置列表框中的选定项.

I don''t understand your question. If you have something in the listbox, it got there somehow, so just runnign the program will load it again.If you''re talking about the selected item(s), just save them to a file, and when the program is loaded, set the selected items in the listbox from that data file''s contents.
