Yes, you can, like:

>

>define class server as session olepublic
>    function sendfile(l_login as string, o_file as base64Binary) as string
>

>The problem is I'm not sure how to specify the second parameter, then save it to file once it's brought in.

A simplified version of my function is like:

* Returns a Slice from an archive
*
FUNCTION GetFileSlice(tcGUID AS STRING, tcarchivo AS STRING, tnposicion AS DECIMAL, tnbuffer AS DECIMAL) AS base64Binary

   LOCAL lnharchivo, lcst

   lnharchivo = FOPEN(lcarchivo,10)
   IF lnharchivo <> -1
      * nos vamos a EOF
      FSEEK(lnharchivo, tnposicion)
      lcst = FREAD(lnharchivo,tnbuffer)
      lcst = CREATEBINARY(lcst)
      FCLOSE(lnharchivo)
      RETURN lcst
   ELSE
      RETURN "-1"
   ENDIF

ENDFUNC

This passes the file in chunks or slices to the client VFP app.

This does the inverse, from the VFP client app to the VFP Webservice (Server Side):

FUNCTION Fich_Bin(tcGUID AS STRING, tcarchivo AS STRING, tntamano AS DECIMAL, tcarchivost AS base64Binary) AS INTEGER

   LOCAL lcarchivo, lnharchivo, lnret
   lnret = 0
		
   lnharchivo = FOPEN(lcarchivo,12)
   IF lnharchivo <> -1
      * nos vamos a EOF
      FSEEK(lnharchivo, 0, 2)
      FWRITE(lnharchivo,tcarchivost)
      FCLOSE(lnharchivo)
   ELSE
      lnret = -1
   ENDIF
   RETURN lnret
ENDFUNC

>All the examples to move pictures have been in .NET, so there's no problem actually declaring the data type in the web service. Fox doesn't have a base64 type, so it's not abundantly clear to me.

VFP7 Supports the data type mapping from the SOAP Toolkit and base64Binary is among then, search by base64Binary in the SOAP Toolkit Help. Use SOAP 2 SP2

Hope this helps.
