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，
