A small project trying to give an answer to the ever so much burning question "what the heck is in my Variant?". See Function MVT.VarType2_ToStr(var)
With a testing environment for this function, and along the way trying to reveal the question completely.

now with enhanced Enum EVbVarType and converting Variant to and from all other datatypes. In VB non intrinsic Variant-datatypes like unsigned types you can convert to and from, you can move, copy, and pass to functions but you can not us it for calculations.
--- Update 2019-aug-06 ---
this wouldn't be complete without showing the use of IRecordInfo. If Your udt is public from a axdll oder typelib, VB can handle it in Variants, where automatically a IRecordeInfo-object is created along with the pointer to the heap-allocated udt-variable, simply by copying (assigning) a udt-variable to a Variant.
