VB2005中picturebox的使用问题

Answer 1

Public Class Form1
Private Sub PictureBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseDown
PictureBox1.Image = System.Drawing.Image.FromFile("C:\3.bmp")
End Sub
Private Sub PictureBox1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles PictureBox1.MouseEnter
PictureBox1.Image = System.Drawing.Image.FromFile("C:\2.bmp")
End Sub
Private Sub PictureBox1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseUp
