Hi Prasanna,
A very good thing you have mentioned in your above post.

But i don't think this is the reply to the post. The approach you said is "adding a user defined library function or functions to your script."
We can have a library file and we can use it at any time.

But now my concern is how can we make a permanent function like "MsgBox".
We can use it in any script, no need to attach any file.
are you getting me,..

I think there might be some approach for creating any ".dll" file and to register..
I hope people will come up with any idea for this post.

Let me know if i am wrong.

Thanks, Jitu
