NE - Masked Edit Control

kids, i've created a masked edit control class, CMaskEdit, in ne. the base class is, of course, ixTextBox. i handle the keyPress event in CMaskEdit and everything works fine except for the fact that it appears that if i don't process the key, it's getting passed along to the base class for processing. q: is there a way to call the base class' handler explicity and prevent the implicit call? if it's a backspace key and a masked character then call base class else do whatever end if am i way off base here? can anyone explain what may be happening here and how keys get routed through? i've tried setting the 'key' variable to 0, but it behaves just like vc++. any insight is greatly appreciate and thanked in advance. thanks! -jason
