I ‘m using the VFP 5. + FTP Service Class
And I need a little help cause I have limited experience with DLL
I need to append to a file on the FTP server
I was doing this with a .bat file and the RUN mybat.bat command

@echo off
c:
cd \ASN
ftp 
open 999.999.999.999
myuser
mypasswo
cd ocum
append test test
bye

This approach work but there is the DOS window opening and closing in run time
To avoid this I like to use the FTP service class but it has no function for appending a file.
I don’t know all the functions available on WinINet.DLL
I understand that some of the syntax goes like

DECLARE Integer InternetGetLastResponseInfo IN WinInet ;
	Integer @nError, String @lpcBuffer, Integer @nMax_Path

But how do I declare an append function?
