原标题:How to make a shape move up and then come back at the bottom once at the top of the screen in Visual Basic.NET?

我可以坐下来,重新站出来,但我可以说明如何开展工作。 任何帮助?

这是我的法典:

    If shpBar.Top + shpBar.Height < Me.Height Then
        shpBar.Top += 50
    Else
        shpBar.Top = 0
    End If

If shpBar.Top > Me.Height Then
    shpBar.Top -= 50
Else
    shpBar.Top = Me.Height
End If

这项工作是否可行?

这应当从两方面着手。

If downwards Then
    shpBar.Top += 50
    If shrBar.Bottom >= Me.Height Then
        shpBar.Top = 0
    End If
Else
    shpBar.Top -= 50
    If shrBar.Top <= Me.Top Then
        shpBar.Top = Me.Height - shpBar.Height
    End If
End If
