I have a class named "myclass" in c:\data\classlib.vcx where a.vcx is my class library

then i have this few codes in my prg file to call "myclass"

set path to c:\data\
set classlib to classlib

frmDetail = createobject("classlib.myclass")
frmDetail.show
read events

However, I got this error msg when it tried to create the object from the class, "Error instantiating the object", saying from the Help that "The server for the object is not registered properly, resources are low, or a required .DLL isn’t present."

What does this means?
Thanks.
