I must be missing something here, the LR says that VarType returns

let's say that I

can I then
tell if it's uint8, int16, uint64 ...? How can I differ between
Int64 and
UInt64?
You can't. Why do you need to? What's stored in the variant is a
value, not a variable.
You may need to know if the original type was a uint8, i6, etc or get
some kind of value conversion when it's not expected.
A dictionary may be the best example where this could happen.
If I do
dim d as new dictionary
d.value("abc") = -1
select case vartype(d.value("abc"))
case ????
myUint8 = d.value("abc")
case ????
myUint16 = d.value("abc")
case ????
myUint32 = d.value("abc")
case ????
myInt8 = d.value("abc")
case ????
myInt16 = d.value("abc")
case ????
myInt32 = d.value("abc")
end select
if it's important that I be able to store key value pairs AND
retrieve the exact same type of value then I need a vartype that
tells me this.
I cannot think of a specific case where this would be required at the
moment, but it's not too hard to see this might be possible.
