你理解错了,我不是说数据的规模多大,是说数据值的范围,比如 1 25 31 33 36 在1--36 范围内,看你给出的数据,最大不超过36,实际数据是不是也这样,最大值不能大于60就可以使用

老师你好,测试数值时,还真是不能大于60,由于我的水平有限,想改到80没有成功,请老师指点,谢谢!

如果不大于90,改一下还是可以的,但效率肯定要下降,如果数值再大,这种方法就不适合了,以下是代码,你试一下
程序代码:

Option Explicit
Sub getmask(mk() As Long)

  Dim i As Long

  ReDim mk(1 To 30)
  mk(1) = 1
  For i = 2 To 30
  
     mk(i) = mk(i - 1) * 2
  
  Next

End Sub
Private Function number1(ByVal a As Long) As Long
  
  number1 = 0
  
  Do While a <> 0
   
    number1 = number1 + 1
    a = a And (a - 1)
  Loop
     
End Function

Private Sub Command1_Click()

    Dim mask() As Long
    Dim t As Double
    Dim data() As Long
    Dim dataStr() As String
    Dim dn As Long
    Dim n As Long
    Dim tn As Long
    Dim tj() As Long
    Dim str As String
    Dim add As Long
    Dim k As Long
    Dim i As Long
    Dim j As Long
    Dim tmp As Long
    Dim tm As Long
     
     
     t = Timer
     add = 300
         
     getmask mask

     dn = 0
     ReDim dataStr(add - 1)
     ReDim data(2, add - 1)

老师你好:
查找按钮中的程序,我想将原:
Open App.Path & "\b1.txt" For Input As #1的数据来源改为文本框text4.text
Open App.Path & "\b2.txt" For Input As #1的数据来源改为文本框text5.text
运行时越界,烦请老师看看,谢谢!!!
问题:
data(1, dn) = data(1, dn) Or mask(tmp - 30)
