Q. Whenever I run my program under the VC++ debugger, I see 'first chance exception' messages which I don't usually see when running in a non-debug environment.

A. Whenever an exception is raised, the debugger will display a "First-chance exception" message. While it is distracting, it is not a problem if the exception is handled . . .

As an example, create a trivial dialog-based application with a pushbutton. In that pushbutton's click handler, place the code: 


    TRY
    {
        CFile::Remove("notaf.ile");
    }
    CATCH
    {
        // ignore
    }
    END_CATCH
When you run the program and click the button, you will get a first-chance exception message, but the program will continue to run without error.
