Hello Erez,
You can try using the DataSocket in CVI, it provides a simple solution for transferring text files to and from a remote computer. DataSocket can accept a number of transfer protocols including http://, ftp://, and dstp://. There are example programs in LabWindows/CVI that uses DataSocket for communication.
You can use DataSocket with LabVIEW, LabWindows/CVI, ComponentWorks, and Tools for Visual C++ software and can find more information on DataSocket at http://www.ni.com/datasocket/
I hope it helps,
Rajiv
