鼠标事件
我开始学习如何在vb.net中进行鼠标事件，而我在msdn上看到的第一个地方有一些代码可以使我滚动.问题是我复制并粘贴了代码，并得到了三个我不理解的错误.好像我缺少图书馆 或我不知道从哪里开始的帮助将不胜感激.
I'm starting to learn how to do mouse events in vb.net and the first place I looked on msdn had a bit of code to get me rolling. Problem is I copy and pasted the code and get a three errors that I don't understand. It seems as though I'm missing a library or something I don't know where to start any help would be appreciated.

VBnoob101，
Hi VBnoob101,
我创建了一个演示并从侧面再现了您的问题，打开Form1.vb [Design]并将文本框控件拖到设计中.
I create a demo and reproduce your issue on my side, open the Form1.vb[Design] and drag textbox control to the design.
然后单击Form1->事件->选择负载->选择加载方式.
Then click Form1 -> event -> select load -> select load method.
与TextBox1.MouseDown方法相同.
The same as TextBox1.MouseDown Method.
最诚挚的问候，
吴可乐
