vb.net - 如果我在访问文件中添加数据，但当通过应用程序输入数据时，我的表工作正常

Question

如果我在访问文件中添加数据，但当通过应用程序输入数据时，我的表工作正常。

我试过断开并重新连接数据集。我也删除了数据集并再次创建，仍然是同样的错误。

Imports System.IO 
Private Sub VehicleEntry_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Me.DetailsTableAdapter.Fill(Me.DbDataSet.Details)

    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        DetailsBindingSource.AddNew()
    End Sub

    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        On Error GoTo SaveErr
        DetailsBindingSource.EndEdit()
        DetailsTableAdapter.Update(DbDataSet)
        MessageBox.Show("New User Added Successfully!")
SaveErr:
        Exit Sub
    End Sub
End Class

未收到错误消息。
