+    ActiveX event parameters can get extremely complex and may be beyond the
+    abilities of wxVariant. If 'operator[]' fails, prints an error messages or
+    crashes the application, event handlers should use GetNativeParameters()
+    instead to obtain the original event information.
+    Calls to operator[] and GetNativeParmeters() can be mixed. It is valid
+    to handle some parameters of an event with operator[] and others directly
+    through GetNativeParameters(). It is \b not valid however to manipulate
+    the same parameter using both approaches at the same time.
