Your IDL claims your object supports ITetraDisp, but in fact it doesn't.

Show your VB code - how exactly do you create the object?

Another possibility is VB using a stale cached copy of the TLB. Remove
TLB reference from the project, delete all files with .oca extension,
add the reference back.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
