Hi,
Any of the following could be the culprit.
a. HelloObj.vb could be in an inaccessible directory (e.g. directory in at a
higher level than the webapplication2 virtual directory or at a different
structure altogether)
b. It hasn't been first compiled into a .dll.
c. It has been compiled but .dll was not referenced into your web project.

Good luck,
..Js
