The way to go should be upload a new empty file overwriting the one on the FTP, with the same filename and path.

Dim wcFTP As New WebClient()

'wcFTP.Proxy = ...
wcFTP.BaseAddress = "ftp://foobar.domain.com"
wcFTP.Credentials = New NetworkCredential("user", "pass") 

Dim sFilePath As String '= ...
Dim sFtpPath As String = wcFTP.BaseAddress & sFolder & Path.GetFileName(sFilePath)

wcFTP.UploadFile(sFtpPath, sFilePath)

Where sFilePath is the path of the empty file with the same name as the one in the server.
