Mike,
All in order in your code. I use same way to send ZIP files to my web server.
My code looks like you.

Set Procedure To wwHTTP AddIt
lcTempPath = Sys(2023)
lcZIPFilename = Addbs(lcTempPath)+Sys(3)+".zip"
lcUploadURL = "http://www.techdata.com/upload.wcs
lcAdminPass = "SomeSecretWord"
oHTTP = Createobject("wwHTTP")

*** Set mode to multi-part form
oHTTP.nHttpPostMode = 2
*** Post a file and a regular form variable
oHTTP.AddPostKey("File",lcZIPFilename,.T.)
*** Post Admin Pass as variable
oHTTP.AddPostKey("AdminPass",lcAdminPass,.F.)
Wait "Please wait... request processing..." Window Nowait
lcHTML = oHTTP.HTTPGet(lcUploadURL)
oHTTP.HTTPClose()


And On server end
lcfilebuffer = REQUEST.getmultipartfile("File",lcfilename)
lcadminpass = REQUEST.getmultipartformvar("AdminPass")
*** Now dump the file to disk
file2var(lcfilename,lcfilebuffer)

Your mistakes might be
1) program can't found "ACCESSTEMP.TXT" on disk. Use FULLPATH() or variable with fullpath
OHTTP.ADDPOSTKEY("AccessUpload", "c:\temp\ACCESSTEMP.txt", .T.)
I thinking error there.... Send for test FILE, and simple var.. check does variable transmitted success.. if file is empty.. check fullpath and file exist.


OTher just notes:
2) I reccomend to use XML instead TXT/DAT file.. because in some cases your tables could have MEMO fields.. and you will need separately encrypt DBF/FPT files.

3) When you use MEMO(Binary) XML encode with Base64. XML is good way.. It might looks overdata.. but its real usefull

4) Also. as transaction result you can send back to your client (which send files to server) XML formatted response (text/xml).
