inherit problem

[Cc]

hi,
is there a way to raise event on base class?

I make a dll project that create alot of class , due to there event that
all the class are using I decide to make a base class and let my other class
to inherit. by doing this I could save problem in case I need to change the
event property. but when I try to raise event on derived class it give me
error (derived class can't rais base class event) .

any suggestion would be great?

Define a 'Protected' sub procedure in the base class (named 'On<event
name>') and call it from the derived class:
