当所有PictureBox在VB中可见时，如何查看另一个表单 - Visual Studio 2010

Question

我在Visual Studio 2010中为使用VB的孩子创建了一个简单的数学游戏。以下是代码

Public Class HSone

    Private Sub HSone_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        'Form Properties
        Me.ControlBox = False
        Me.FormBorderStyle = Windows.Forms.FormBorderStyle.FixedSingle
        Me.Text = ""
        Me.Size = New System.Drawing.Size(907, 574)

        'On load Hide Objects
        PictureBox1.Visible = False
        PictureBox2.Visible = False
        PictureBox3.Visible = False
    End Sub

    Private Sub Label1_Click(sender As System.Object, e As System.EventArgs) Handles Label1.Click
        PictureBox1.Visible = True
    End Sub

    Private Sub Label2_Click(sender As System.Object, e As System.EventArgs) Handles Label2.Click
        PictureBox2.Visible = True
    End Sub

    Private Sub Label3_Click(sender As System.Object, e As System.EventArgs) Handles Label3.Click
        PictureBox3.Visible = True
    End Sub

    Private Sub Label2_MouseHover(sender As System.Object, e As System.EventArgs) Handles Label3.MouseHover, Label2.MouseHover, Label1.MouseHover
        Cursor = Cursors.Hand
    End Sub

End Class

当所有图片框现在可见时，如何查看下一个表格？ 谢谢！
