请高手支招！！！

我从别人那得到一个计算树木的材积程序，我想通过它转成access中的程序模块，但出现了错误，请各位好友指点哦！！！小子不胜感激。

10 D%=3

20 DIM A#(3),B#(3),C#(3),A1#(3),B1#(3)

30 DIM A2#(5,3),B2#(5,3),K%(5,3)

40 FOR I%=1 TO 3

50 READ A#(I%),B#(I%),C#(I%),A1#(I%),B1#(I%)

60 NEXT I%

70 FOR I%=1 TO 5

80 FOR J%=1 TO 3

90 READ A2#(I%,J%),B2#(I%,J%),K%(I%,J%)

100 NEXT J%

110 NEXT I%

上为GWBASIC程序，

以下是我在access中写的模块：

Function treev()



Dim K As Integer

Dim A(2) As String, B(2) As String, C(2) As String, A1(2) As String, B1(2) As String

Dim A2(0 To 4, 0 To 2) As String, B2(0 To 4, 0 To 2) As String, K2(0 To 4, 0 To 2) As String

我倒，这种东西也找到了.主要先要把这个程序读懂 然后根据数理逻辑 把 “DATA .000058061860,1.9558851,.89408804,.10945,.97432 ”语句的内容改成Acess的表   " READ A#(I%),B#(I%),C#(I%),A1#(I%),B1#(I%) "语改为 用DAO 或 Ado 的记录集 去访问表中的数据

  " READ A#(I%),B#(I%),C#(I%),A1#(I%),B1#(I%) "语改为 用DAO 或 Ado 的记录集 去访问表中的数据

关健在此，我就是不知怎样将表中的数据赋于数组

yangzn

    Dim rst As New ADODB.Recordset

    Dim a() As Variant  '如果数组知道长度，就用定长数组，变量类型也是如此

    Dim i As Long

    '这里插入 rst的打开

    '并定位到你要的那条记录

    '然后....

   

    ReDim a(rst.Fields.Count)

    For i = 0 To rst.Fields.Count - 1

        a(i) = rst(i)

    Next i
