I do have a structure like this.

Type struct_name
 name   as  string
 number as  integer
 total  as  long
end type

COM API looks like this

short Fn(VARIANT *pData, long *pNum); //COM function
Function will accept the VARIANT.vt parameter as VT_UI1 | VT_ARRAY and
parray as SAFEARRAY.

How i can call this funtion from VB? And how pointer variables can be
passed to a function.
