急！insert into 语句问题！

在注册界面注册信息进Access数据库中去

Imports System.Data
Imports System.Data.oledb
Public Class register
    Dim mybind As BindingManagerBase
    Dim olestr As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=register.mdb"
    Dim oleconn As New OleDbConnection(olestr)
    Dim oleadap As New OleDbDataAdapter()
    Dim oledset As New DataSet()
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        oleconn.Open()
        Dim id As New OleDbParameter("@id", OleDbType.Char, 10)
        Dim password As New OleDbParameter("@password", OleDbType.Char, 10)
        Dim name As New OleDbParameter("@name", OleDbType.Char, 10)
        Dim olesql As String =
        "insert into t_register(id,password,name)" & "values(@id,@password,@name)"
        Dim olecmd As New OleDbCommand(olesql, oleconn)
        olecmd.Parameters.Add(id)
        olecmd.Parameters.Add(password)
        olecmd.Parameters.Add(name)
        id.Value = TextBox1.Text
        password.Value = TextBox2.Text
        name.Value = TextBox4.Text
        olecmd.ExecuteNonQuery()
        oleconn.Close()
   End Sub

异常：在olecmd.ExecuteNonQuery()处提示：INSERT INTO 语句的语法错误。
不知道怎么回事？谢谢各位大虾解答下
--------------------编程问答-------------------- "insert into t_register(id,[password],[name]) values('"& id &"','"& password &"','"& name &"') "

字符型变量引用：'"& 变量名 &"'
数值型变量引用："& 变量名 &" --------------------编程问答-------------------- 像那样改的话
还是有问题啊 --------------------编程问答--------------------

Dim olesql as string = "insert into t_register(id,password,name) values(?,?,?)"

补充：VB ,  数据库(包含打印，安装，报表)
