急高手帮忙教下怎么用VB.NET2008做个查询学生课程信息的资料库啊？？？

我用vb做了一个程序对数据库中的数据进行排序，程序如下：

标准模块：

Type nas

custno As Integer

last_name As String

first_name As String

vip_status As String

address1 As String

assress2 As String

city As String

state As String

post_code As String

country As String

phone As String

fax As String

email As String

remarks As String

End Type

窗体模块：

Option Base 1

Dim aa(30) As nas

Dim t As nas

Private Sub Command1_Click()

Open "e:\vbb\custoly.db" For Random As #1

For i = 1 To 30

Get #1, i, aa(i)

i = i + 1

Next i

For j = 1 To 29

For k = j + 1 To 30

If aa(j).last_name aa(k).last_name Then

t = aa(j)

aa(j) = aa(k)

aa(k) = t

End If

Next k

Next j

For p = 1 To 30

print aa(p).last_name

Next p

End Sub
