"As Any" in a UDT ?

I am trying to translate some C code into VB.

There is a C Structure where one of the members is declared "As Any"

VB doesn't accept "As Any" as a data type for UDT members.

What is the corresponding data type that I should be using for that UDT member?

Thanks.

EDIT :
To be more precise, I should note that the C structure member is actually declared As LPVOID which, to my understanding, corresponds to "As Any" in VB.
