迷失于VB.Net SQL插入查询

Question

所以我遇到了一个问题，我终于得到了没有错误的代码，但数据库实际上没有显示更新。

我运行了一些代码，我认为它会转到.pdb文件。它会一直到那里只使用.mdb文件作为模板吗？

Private Sub NextButton_Click(sender As Object, e As EventArgs) Handles NextButton.Click

    Dim count As Integer = 0
    Dim insertSql As String = "INSERT INTO StudentTable(BadgeNo,FirstName,LastName,SAPID,Email,Phone,College) VALUES (?,?,?,?,?,?,?)"
    Dim connStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=""C:\Users\larsennicholasg\Documents\Visual Studio 2012\Projects\SSCLogin\SSCLogin\My Project\SSCStudent.mdb"""
    Using conn As New OleDbConnection(connStr), cmd As New OleDbCommand(insertSql, conn)

        cmd.Parameters.Add("?", OleDbType.Integer).Value = CInt(BadgeNoTextBox.Text)
        cmd.Parameters.Add("?", OleDbType.WChar, 255).Value = FirstNameTextBox.Text
        cmd.Parameters.Add("?", OleDbType.WChar, 255).Value = LastNameTextBox.Text
        cmd.Parameters.Add("?", OleDbType.Integer).Value = CInt(SAPSIDTextBox.Text)
        cmd.Parameters.Add("?", OleDbType.WChar, 255).Value = EmailTextBox.Text
        cmd.Parameters.Add("?", OleDbType.WChar, 255).Value = PhoneTextBox.Text
        cmd.Parameters.Add("?", OleDbType.WChar, 255).Value = CollegeComboBox.Text

        conn.Open()
 If (cmd.ExecuteNonQuery() = 1) Then 
    MessageBox.Show("Success") 
  Else
    MessageBox.Show("Nerp") 
 End If



        conn.Close()

    End Using


    Me.Hide()
    TestPull.Show()


End Sub
