Have a problem with this c# windows form button on my project. I have to turn this in on Saturday and I have worked on this and cannot get this to work.

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; using System.Data.SqlClient; using System.Configuration;

namespace AnticSoftware_T4 { public partial class enrollastudentinaCourseForm : Form

{ string connectionString; SqlConnection conn; public enrollastudentinaCourseForm() { InitializeComponent(); connectionString = ConfigurationManager.ConnectionStrings[ "AnticSoftware_T4.Properties.Settings.TinyCollegeDBConnectionString"] .ConnectionString; }

private void closeButton_Click(object sender, EventArgs e) { Close(); }

private void enrollastudentinaCourse_Load(object sender, EventArgs e) { using (conn = new SqlConnection(connectionString)) using (SqlDataAdapter adapter = new SqlDataAdapter ("SELECT * FROM student", conn)) { DataTable studentTable = new DataTable(); adapter.Fill(studentTable); selectaStudentComboBox.DisplayMember = "studentName"; selectaStudentComboBox.DataSource = studentTable; } }

private void selectaStudentComboBox_SelectedIndexChanged(object sender, EventArgs e) {

}

private void selectaCourseComboBox_SelectedIndexChanged(object sender, EventArgs e) { }

private void enrollButton_Click(object sender, EventArgs e) { } } }
