Here Is It::

Event OnAdd(byval Result as long) 'The Arg Is Optional

Dim Res as long

Private Sub Form_Load()
AddNums 10,10
end sub

private sub AddNums(a as long,b as long)
Res=a+b
RaiseEvent OnAdd(Res)
end sub

private sub Form_OnAdd(byval Result as long)
msgbox Result
end sub

I don't understand, in this code example the source and the destination of the message are the same. The form is sending a message to itself. Why should you do something like this?
If there is an external event (outside of the form) that must fire an event on the form you must create an extra class that can fire events. Look up the WithEvents keyword and the Event statement in the VB help files.

You Can Have Events In The Class Modules Or The User Controls You Create. And Those Events Can Be Handled In Your Forms.

Yes, that was I mean. You need a event source (control or another class) and an event destination such as a VB form. No offence but if you create sample code as you did, it is must clearer if I create a completly working code sample that can be with cut and paste directly injto VB. Thanks.
