i would want to create an object dynamically. i.e i hold my class name in a variable only.and by passing this variable can i create the object of the type (value which the variable holds)

eg :

dim str as string
str="active"

i wanna create an object of type active during runtime as the val of str can keep changing

Not easily possible, Ive seen this question asked before and there was a
solution, however, i seem to remember it was a rather convoluted answer.
