Title Body

Working on a class assignment in C#, I came across a program crash without any error (except what's written in VS2010's debug window). Here is the typical code causing the crash : public partial class Test : Form { public Test() { InitializeComponent(); } private void Test_Load(object sender, EventArgs e) { ColumnHeader header; header = new ColumnHeader(); header.Text = "#"; header.TextAlign = HorizontalAlignment.Center; header.Width = 30; listView1.Columns.Add(header); TimerCallback tcb = this.UpdateListView; System.Threading.Timer updateTimer = new System.Threading.Timer(tcb, null, 0, 1000); } public void UpdateListView(object obj) { ListViewItem item; listView1.Items.Clear(); for (int i = 0; i < 10; i++) { item = new ListViewItem(i.ToString()); listView1.Items.Add(item); } } } ... what am I missing here? ** EDIT ** There's no error, the program just ends like if I would call System.Environment.Exit(0); A first chance exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll The program '[4644] ProgramTest.vshost.exe: Managed (v4.0.30319)' has exited with code 0 (0x0). The program '[4644] ProgramTest.vshost.exe: Program Trace' has exited with code 0 (0x0).
