vb.net中的statusstrip控件

请参阅下面的演示以帮助您前进。您从未说过您使用的是哪个版本的dot net，请参阅.Net 3.5及以上版本的tick事件

See the demo below to get you going. You never said which version of dot net you were using, see the tick event for info on .Net 3.5 and above

创建各个状态条项目，然后通过代码将文本和值分配给这些项目。

Create the individual status strip items and then assign the text and values through code to these items.
