我只想根据datagridview中显示或填写PictureBox1的所选行显示图像，当点击另一行时，另一个图像将根据插入其他注册所有者的图像填充框.MySql是我的数据库

这是我的代码

Private Sub DataGridView1_CellMouseClick(ByVal sender As Object, _
           ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) _
           Handles DataGridView1.CellMouseClick
    cmd = New MySqlCommand("select ownpic from owners", con)
    Dim imageData As Byte() = DirectCast(cmd.ExecuteScalar(), Byte())
    If Not imageData Is Nothing Then
        Using ms As New MemoryStream(imageData, 0, imageData.Length)
            ms.Write(imageData, 0, imageData.Length)
            PictureBox1.BackgroundImage = Image.FromStream(ms, True)
        End Using
    End If


End Sub
