How do I set up a button to switch images in vb?

In VB, you can use the MouseEnter and MouseLeave events of a button to achieve button image swapping. Here is an example code:

Private Sub Button1_MouseEnter(sender As Object, e As EventArgs) Handles Button1.MouseEnter
    Button1.BackgroundImage = My.Resources.Image2 '设置鼠标悬停时的图片
End Sub

Private Sub Button1_MouseLeave(sender As Object, e As EventArgs) Handles Button1.MouseLeave
    Button1.BackgroundImage = My.Resources.Image1 '设置鼠标离开时的图片
End Sub

In the above code, Button1 is the name of the button that needs to be set, and Image1 and Image2 are two different images for the button (you can use My.Resources.ImageName to reference the project’s resource images).

When the mouse pointer enters the button area, the MouseEnter event is triggered, which sets the button’s background image to Image2; when the mouse pointer exits the button area, the MouseLeave event is triggered, setting the button’s background image to Image1.
