        MsgBox("太阳升起")
    End Sub

    Private Sub MonthCalendar1_DateSelected(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DateRangeEventArgs) Handles MonthCalendar1.DateSelected
        Label1.Text = MonthCalendar1.SelectionStart & "到" & MonthCalendar1.SelectionEnd
    End Sub

    Private Sub pic_btn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles pic_btn.Click
        If PictureBox1.Visible = True Then
            PictureBox1.Visible = False
            pic_btn.Text = "显示图片"
        Else
            PictureBox1.Visible = True
            pic_btn.Text = "隐藏图片"
        End If
    End Sub
