1. Using the 'FtpCommand' of wininet.dll

• Posted by sergelli Aug 19, 2009

Hello everybody. I am trying to use the library of "Wrapper for Wininet.dll"posted on contributions from users, of Fabio Ramires.

But the "FtpCommand" with the file 19FTPCommand.exw example, is not working. Within the code, in its comments, Mister Fabio warns that some functions may not work depending on the version of the file WININET.DLL, however, already tested with win98 versions, Millennium, and XP, but still not working (does not return results).

I need this function to obtain the information contained in directories from an FTP server to know what are the folders and files in the directory current. But, the program returns an empty string.

Please, someone had a code worked well, with this function? or otherwise, how can I make this program work correctly

Thank you very much.

include EInetLib.ew
 
integer res 
 
atom ses1, con1, han1 
 
ses1 = InternetOpen({}) 
 
con1 = InternetConnect({ 
  {"session_id",ses1}, 
  {"server_name","ftp.winzip.com"}, 
  {"service","FTP"}, 
  {"user_name","anonymous"}, 
  {"password","someone@example.com"} 
  }) 
 
if con1 then -- The FTP connection could be stablished 
 
  Msg(InternetGetLastResponseInfo()) 
 
  -- Since in this case we expect a response FtpCommand returns 
  -- a Internet file handle that can be used to read the response 
  han1 = FtpCommand({ 
                       {"connection_handle" ,con1}, 
                       {"expect_response",TRUE},  
                       {"command","LIST"}, 
                       {"flags","ASCII"} 
                    }) 
                    
  Msg(InternetGetLastResponseInfo()) -- this is normal server response 
 
  -- Now let's read what the server sends 
  -- For simplicity we are just going to  
  -- read the first 4096 bytes of LIST given by server 
  Msg(InternetReadFile(han1, 4096))  
   
else  
  Msg(net_err_msg) 
end if 
 
res = InternetClose(ses1)

It seems like I replied in the wrong thread, so I'll post it here as well:

You can try adding {"flags","PASSIVE"} to the options list when calling InternetConnect. 
 

I was assuming that you had already changed the hostname/username/password to something other than Fabio's settings.

The source code only seems to support "ASCII" as an option for flags.

Flags = FTP_TRANSFER_TYPE_BINARY
  Parameter = ParameterValue("flags",NULL, options) 
  if sequence(Parameter) then  
    if  equal(upper(Parameter),"ASCII") then  
      Flags = FTP_TRANSFER_TYPE_ASCII 
    end if 
 
    -- there should be something here to 
    -- check for a combination of flags 
 
  end if 

Just hit Ctrl+C when the message box is in focus. It will copy all the text on the message box. Then I just edit out the stuff I don't need.

Example:

--------------------------- 
Wininet 
--------------------------- 
220 spftp/1.0.0000 Server [204.2.225.144] 
331 Password required for USER. 
230 Welcome to WinZip's FTP site. 
 
--------------------------- 
OK

The source code only seems to support "ASCII" as an option for flags. 

con1 = InternetConnect({  
  ...  
  ...  
  ...  
  {"flags","PASSIVE"}  
  })

Sorry emphasize this. However, is impossible to think that no one else is having this problem, While Greg has done work on your PC.

I just test the code on a third computer, and the problem continues.

I am now using a laptop Semp-Toshiba with WinXP with all programs Euphoria updated. These are the messages (5) received after run the code of Fabio Ramires, posted above by Greg.
