C# : "A first chance exception of type 'System.InvalidOperationException'"
c#, crash
Solution
If you check `Thrown` for `Common Language Runtime Exception` in the break when an exception window (Ctrl+Alt+E in Visual Studio), then the execution should break while you are debugging when the exception is thrown.
This will probably give you some insight into what is going on.
Problem
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). ```
