Hi ranjeet44, can you specify in a better way what is your goal? Do you have to transfer file, make host and guest communicate together, simulate remote connection, connect from a remote system to your guest system through the host... what?
Anyway in Virtualbox you can simply install, in your guest system, the VirtualBox Guest Additions, that make you copy/paste text, share host and guest files via shared folders, enable various screen sizes including full-screen, and so on.
They are a .iso virtual CD, that should have been automatically downloaded when you installed VirtualBox on your host system (i have it in
/usr/share/virtualbox/VBoxGuestAdditions.iso on my Debian, but the path could be different for your installation. In Windows you find them in the installation folder. Or you can download the one appropriate for your version
here, in the folder having your version number), and you only have to insert this CD in any virtual machine you want to extend with those features. Then you procede with the installation on your guest system (
here the official guide, but you can google for it) and you are ready to go. Usually the installation doesn't require particular operations. If you have problems there are lots of discussions and documents on the web about installation issues, or ask here.
Having said that, I suggest you to use VirtualBox instead of VMWare. After all... it's open and free! And for my experience it's also very stable.
Have fun... keep us up to date.
Bye.
