But in your case you need to quadruple the double-quotes actually. See also here:

I try to put the file name inside the double quoute but still i couldn't upload filename with space

p.Arguments = "/console /command " & """" & "option batch on" & """ " & """" & "open " & My.Settings.FTPUsername & ":" & My.Settings.FTPPassword & "@" & My.Settings.FTPIp & """ " & """" & "put "" " & My.Settings.DestinationPath & "\" & vgrid.Item(1, i).Value '& " "" "" " & """" & "exit" & """"
