  • 第1题：

    为了使命令按钮(名称为Command1)右移200，应使用的语句是

    A．Command1.Move-200

    B．Command1.Move200

    C．Command1.Left=Command1.Left+20

    D．Command1.Left=Command1.Left-200


    正确答案：C
    解析：本题考查命令按钮控件的属性。题目要求命令按钮右移200，也就是说距离左边框的距离增加200，使用Left属性可以实现。 Left则是距离窗体左边框的距离，所以本题正确答案是选项C。考生需要注意，命令按钮没有Move属性。
