单位有个竞赛活动,然后用PPT做了个人员抽点的小程序,需要最后控制人员抽点的顺序,抽到特定的人员,但是不知道怎么实现这个效果,现求助大佬。
Dim flag As Integer '全局变量用于查询是否按下停止键
Sub delay(T As Single)
Dim time1 As Single
time1 = Timer
Do
DoEvents
Loop While Timer - time1 < T
End Sub
Private Sub 开始_Click()
flag = 0
'Dim StuData(500) As Person
'StuData() = 0
Dim StuData(500) As String
Dim buf As String
Dim i As Integer
i = 0
Open "E:\人员名册.txt" For Input As #1
'Open "E:\output.txt" For Output As #2
Do While Not EOF(1)
Line Input #1, buf
'Write #2, buf
StuData(i) = buf
i = i + 1
'在循环中将姓名输入数组
Loop
'Close #1
'Close #2
Dim index As Integer
Dim tims As Integer
times = 0
'循环显示姓名1
Do Until (times > 65534 Or flag <> 0)
index = Int((i * Rnd) + 0)
Label1.Caption = StuData(index)
times = times + 1
delay (0.05)
Loop
Close #1
End Sub
Private Sub 停止_Click()
flag = 1
End Sub
用到的代码就是以上代码
使用方法,编辑names文件,每个名字1行
注意,需要抽取的人,名字后面加上一个空格
不希望抽取的人,不要加
则程序滚动的时候,所有人都参与滚动,停止的时候,有空格的才会出来
Option Explicit
