OleDbException が処理されませんでした...From 句の構文エラー

ログイン用の私のコードを以下に示します。

Imports System.Data.OleDb

Public Class Login

Dim con As New OleDbConnection
Dim dt As New DataTable
Dim ds As New DataSet

Private Sub Login_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    con.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\Project work\anshu\fitness_0.1\Fitness.accdb"
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btncancel.Click
    Me.Close()

End Sub

Private Sub btnlogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnlogin.Click


    If check() = True Then
        Main.Show()
        Me.Hide()
    Else
        MsgBox("Enter vailid Username and Password", MsgBoxStyle.Information, "Login Validation Information")
    End If



End Sub

Public Function check()
    ds.Tables.Add(dt)
    con.Open()
    Dim da As New OleDbDataAdapter("select * from User", con)
    da.Fill(dt) ---->here is the error!

    For Each DataRow In dt.Rows
        If txtname.Text = DataRow(1) And txtpass.Text = DataRow(2) Then
            con.Close()
            Return True

        End If
    Next
    con.Close()
    Return False

End Function

End Class

ユーザーは予約語であり、括弧で囲む必要があります。
