Hi all

I am having vb.net application which is using reference of dll which
is created in ATL COM.
I have one method in COM dll which i am calling in vb.net.
First time application is working find. But if i try to call same
method again without closing program, application is giving error that
object reference not set(unhandled exception). I don't know why this
is happening.
Does anyone have any idea bout this problem.

Please help.
Thanks in advance.

You need to provide some code in your question. Otherwise, this is too
little to go on.
It sounds like you have dropped the reference to the object.

I assume that your object has a wrapper. If you don't know about runtime
callable wrappers, then perhaps this will help:
