关于数据库数据的加密问题！(100分)

为何不用Interbase 6.0?

也不是超级麻烦呀，统计的时候你把加密的数据用计算字段显示不就可以了吗

to 左右手：
　　比较有效地加密过的数据不能进行模糊查询啊！

不用密碼,用權限,在登錄時存On_load加入
Option Compare Database
Sub SetStartupProperties()
Const DB_Text As Long = 10
Const DB_Boolean As Long = 1
ChangeProperty "StartupForm", DB_Text, "Customers"
ChangeProperty "StartupShowDBWindow", DB_Boolean, False
ChangeProperty "StartupShowStatusBar", DB_Boolean, False
ChangeProperty "AllowBuiltinToolbars", DB_Boolean, False
ChangeProperty "AllowFullMenus", DB_Boolean, True
ChangeProperty "AllowBreakIntoCode", DB_Boolean, False
ChangeProperty "AllowSpecialKeys", DB_Boolean, True
ChangeProperty "AllowBypassKey", DB_Boolean, True
End Sub

Function ChangeProperty(strPropName As String, varPropType As Variant, varPropValue As Variant) As Integer
Dim dbs As Object, prp As Variant
Const conPropNotFoundError = 3270

Set dbs = CurrentDb
On Error GoTo Change_Err
dbs.Properties(strPropName) = varPropValue
ChangeProperty = True

Change_Bye:
Exit Function

Change_Err:
If Err = conPropNotFoundError Then ' 找不到屬性。
Set prp = dbs.CreateProperty(strPropName, _
varPropType, varPropValue)
dbs.Properties.Append prp
Resume Next
Else
' 未知的錯誤。
ChangeProperty = False
Resume Change_Bye
End If
End Function


Private Sub Command0_Click()
On Error GoTo Err_Command0_Click


DoCmd.Close

Exit_Command0_Click:
Exit Sub

Err_Command0_Click:
MsgBox Err.Description
Resume Exit_Command0_Click

End Sub
Private Sub Command1_Click()


ChangeProperty "AllowBypassKey", DB_Boolean, True


If Me!UesrName = "wyn" And Me!Password = "085477" Then

Else
MsgBox "密碼錯誤"
End If



End Sub
Private Sub Command2_Click()
ChangeProperty "AllowBypassKey", DB_Boolean, Flase
DoCmd.Close
End Sub

Private Sub Form_Load()
ChangeProperty "AllowBypassKey", DB_Boolean, False
End Sub
我就是這么做的

接受答案了.
