Raise .NET events from Visual Basic 6.0

[askingBoy]

Hello , I would like to know how to make this :
I have a library written in Visual Basic .Net that has some events for its
class , I am making an instance of this class in a Visual basic 6.0 Project
and I can call the methods from the object I instanced .
However I cannot raise the events from this library with my object , I
already made a sub in the vb 6.0 in the form :

Private Sub object_Event()
'Some code here
End Sub

But the subroutine is never called .

I declared the object with the word "WithEvents" in Vb 6.0 in this way :

Private WithEvents object As library.class

But when I try to compile the project a dialog appears :

"Object does not source Automation events"

What can I do ? ; I had tried the library from a VB NET project and I can
raise the events normally . I registered the library for COM programming in
This way :

regasm library.dll /tlb: library.tlb

Is there something I am missing ?
Thank You very much for your help .
