First Chance Exception: WebBrowser Control

Question

See the code in this thread . 
There are VB and C# versions of a demo Web Browser Control and a Progress Bar.

However, the VS Output Window shows the following whenever it navigates to a URL.

A first chance exception of type 'System.ArgumentOutOfRangeException' occurred in System.Windows.Forms.dll

But, execution does not break for it. 
The following does not even catch it.


    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            try
            {
                Application.Run(new WebBrowser());
            }
            catch
            {
            }
        }
    }

How would I trace this down?

Thanks ahead of time.

Answer 1

First chance exception is usually safe to ignore. Here, it means that a Windows.Forms internal method did something that threw an exception but it was gracefully caught and handled.

Thanks. 
I've seen these before with other types of messages in the Forms.dll but have never tried to track them down.

You can do a little bit of tracking down if you want to. Just use the Debug/Exceptions dialog and tell the debugger to break on any thrown ArgumentOutOfRangeException. And when the debugger breaks, use the call stack to figure out what WinForms method threw - and then use Reflector to go look at that method. That'll give you a fairly decent idea of what has happened to cause the exception.
