问题 单项选择题

某程序列表框中有许多项，现在用Timer控件控制时间，0.1秒删除一项，直到删完为止，用一滚动条来显示删除的项目，请选择合适的语句，完成此程序( )。



Private Sub Command2_Click()

HSeroll1.Min=0

HScroll1.Max=List1.ListCount

HScroll1.Value=0

Timer1.Interval=______

Timer1.Enabled=True

End Sub

Private Sub Timer1_Timer()

If List1.ListCount>0 Then

List1.RemoveItem 0

HScroll1.Value=HSeroll1.Max-List1.ListCount

Else

Timer1.Enabled=______

MsgBox"全部删除!"

End If

End Sub

答案

参考答案：A

解析： 本题的难点在于考生能从全局上读懂代码，在按钮的单击事件中，设置时钟控件的时间间隔，其单位是毫秒，所以0.1秒应设置为100毫秒；在Timer事件中，如果已经全部删除列表框中的内容，则应将Timer1关闭，不再执行删除操作，所以Enabled属性应该设置为False。

In January 2011, Han, Ita and Jo formed a partnership, under the Partnership Act 1890, to run a pottery business trading under the name HIJ Potteries. On formation, Han introduced ￡6,000 into the business, Ita introduced ￡3,000 and Jo introduced ￡1,000. All of them took an active part in the operation of the business and the partnership agreement stated that all profits and losses should be divided in proportion to the capital contribution. However, as Jo was the person who would actually be making the pottery, it was agreed that she would not be liable for any more than her initial contribution towards any future debts. After some time, Han provided the partnership with a loan of ￡1,000 in order to sustain the operation of the business.Unfortunately, the business was not successful and made significant losses.
