VS 2008 TightVNC File transfer

hey guys so I have made a program with vncsharp (Using Visual Basic 2008 (VB9?))

I am trying to impliment some type of file transfer, I have tried tightVNC source (C++) but to no avail.

Could some one point me in the right direction?

PS I do not want to install anythingon the server other than tightVNC.
