写入调用数据库help!help!help!help!help!help!help!

请大虾给我指点迷津.
我在做串口通信的毕业设计,(水文测量),我要实现的功能是从测量器件(单片机)接收数据,数据包括年,月,日,时,分,秒,水位数据,都是以二进制传送到串口,然后存储到数据库中(Access),
对于数据库程序的编写,我不太懂,数据应当如何写入数据库,然后又如何调用,使数据能够以十进制显示在文本框(text)中,

写入数据库的例子
Public Function M_Access(M_AccessName As String)
Dim M_temp As String
Dim M_Error As String
On Error GoTo ine
Set conn = New Connection
Set rs = New ADODB.Recordset
M_temp = ""
M_temp = App.Path + "\" & M_AccessName & ";"
conn.Open "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source=" & M_temp & ";"
Set rs = conn.Execute("select * from login where number=1")
'这里可以用Insert,Update等SQL语句.
rs.Close
conn.Close
GoTo inerr
ine:
M_Error = "数据库错误号：" & Err.Number & " 错误内容：" & Err.Description
MsgBox M_Error, , "错误信息"
inerr:
Set rs = Nothing
End Function

建议你先交二进制转换成 字符串，然后在存入数据库，建议用Text类型存储。

多谢大虾指点，能否详细点，比如如何将二进制转换成字符串，还有vb界面的设计，

我以前写的代码
这是关于二进制串口读取的例子，已经通过且正在使用。看看吧。
Public Function M_DuBang(MSComm1 As MSComm) As String
Dim p_input As String
Dim p_num(7) As String
Dim P_Number As String
Dim p_pathf As String
Dim a As Integer
On Error GoTo ine
'Text1.SetFocus
'Do
'Text1.Text = ""
With MSComm1
.CommPort = 1
.Settings = "1200,n,8,1"
.PortOpen = True
End With
Do
Loop While MSComm1.InBufferCount < 21
If MSComm1.InBufferCount >= 20 Then
p_input = ""
p_input = MSComm1.Input ’p_input就是串口的数据。
GoTo inerr
ine:
MsgBox Err.Description, , "错误信息"
inerr:
MSComm1.PortOpen = False
'Loop While stops = True
End Function
