Thats because there is a System.EventArgs parameter called 'e' passed
into the event handler. Simply give the variable in the exception
handler a different name


try {
  decimal aValue = Decimal.Parse(TextBox3.Text);
  TextBox3.Text = System.String.Format("{0:C2}", aValue);
}
 catch (FormatException exception) {
 MessageBox.Show("Error: " + exception, "Error Formatting Total",
				 System.Windows.Forms.MessageBoxButtons.OK,
MessageBoxIcon.Asterisk);

}

Also, the code above will use the .ToString() method of the
FormatException class which, IIRC, will also include a full stack
trace. If you only want to see the actual error message, use
exception.Message.

And in case you weren't aware, exceptions may also be wrappers for
other exceptions (especially if an exception has been handled and
rethrown as a different type). So in some circumstances it may be
desirable to navigate down the Exception.InnerException chain to get
the full exception details.

HTH.
