Private Sub Command1_Click()
Dim i As Integer, j As Integer, k As Integer, p As Integer
Dim t As Single
For i=1 To 7
k=i
For j=i+1 To 8
If Then
k=j
End If
Next j
If k<>i Then
p=a(i):a(i)= a(k):a(k)= p
t=b(i):b(i)= b(k):b(k)= t
End If
Next i
For i=1 To 8
List2.AddItem Str(a(i))&“道:”& Str(b(i))
Next i
End Sub
Private Sub Text1_KeyPress(KeyAscii As Integer) ’按回车键录入比赛成绩
