Example:
// some part of app builds an array
dim a() as pair
a.Append 1:"Hello"
a.Append 2:"World"
// passes it as Variant somewhere else
dim v as Variant = a
// and later you may want to get values back without knowing the array type
// this raises TypeMismatchException
'dim o() as Object = v
// so use plugin to get objects:
dim v1 as Variant = GetVariantArrayValueMBS(v, 0)
dim v2 as Variant = GetVariantArrayValueMBS(v, 1)
// now you can check type and cast to the object type
dim p1 as pair = v1
dim p2 as pair = v2
MsgBox p1.Right+" "+p2.Right
