INSERT into语句中的语法错误（OLEDB）

Question

我的INSERT语句有语法错误，但我不知道在哪里。错误消息显示第13行有，但我无法看到问题。有人可以帮忙吗？

 Imports System.Data.OleDb

Public Class Form2
Dim cnn As OleDbConnection
Dim cmd As New OleDbCommand
Dim sqlstr As String
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
    Try
        cnn = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & Application.StartupPath & "\Library.accdb;")
        cnn.Open()
        sqlstr = "INSERT INTO Users (ID,User_Name,Password) VALUES ('" & txtID.Text & "','" & txtUser.Text & "','" & txtPassword.Text & "')"
        cmd = New OleDbCommand(sqlstr, cnn)
        cmd.ExecuteNonQuery()
        cnn.Close()
        MsgBox("User saved.")
    Catch ex As Exception
        MsgBox(ex.ToString)
    End Try
End Sub
