Please note that not all methods need parameters, and not all methods need a return value. I just meant to point out this general rule: that IF a method returns a value, inheritance can be broken, not only by forgetting DoDefault(), but also by forgetting to return the correct value.

>>>Several methods in the default classes (which I have subclassed) use predefined methods that receive parameters. For example most Error methods receive nError, cMessage, nLine & the Keypress event gets nKeyCode, nShiftAltCtrl. I like to add capability to these methods and am having trouble calling the default code.

>>>In Error's case I have used DODEFAULT(nError,cMessage,nLine) to allow those errors I don't trap to be processed normally. But nothing seems to happen using this syntax. I have had to find some code from another component and paste it in instead of the dodefault.

>>>In Keypress again I added DODEFAULT(nKeyCode, nShiftAltCtrl). This caused the object to only be one character long and the value to contain only the last character typed. Again I programmed around it with custom code all the way.

>>>Obviously, I would prefer not to custom code everything if I can help it. It is ineffient and prone to unforseen errors.
