Question

FTPPutFile Example

Asked by: pr_wainwright

Hi,
     I recently found some code on the internet to upload a file to my web site but I can't seem to get the parameters correct.

I tried upload_file('123.123.123.123', '/Httpdocs/', 'C:\Test\1TestFile.txt', '/Httpdocs/1TestFile.txt', 'myusername', 'mypassword');

and several variations but nothing seems to work.

Any help appreciated.

function upload_file(remote_server, 
                     directory, 
                     local_file, 
                     remote_file, 
                     user, 
                     pass: PAnsiChar): boolean; 
var hInet, hConnect: HINTERNET; 
    Dir, Put: Boolean; 
begin 
hInet := InternetOpen(nil, INTERNET_OPEN_TYPE_DIRECT, nil, nil, 0); 
hConnect := InternetConnect(hInet, 
                            remote_server, 
                            INTERNET_DEFAULT_FTP_PORT, 
                            user, pass, 
                            INTERNET_SERVICE_FTP, 
                            INTERNET_FLAG_PASSIVE, 
                            0); 
Dir := ftpSetCurrentDirectory(hConnect, directory); 
WaitForSingleObject(Cardinal(Dir), infinite); 
Put := ftpPutFile(hConnect, local_file, remote_file, FTP_TRANSFER_TYPE_BINARY, 0); 
InternetCloseHandle(hInet); 
InternetCloseHandle(hConnect); 
Result:= Put; 
end;

Did you try

upload_file('123.123.123.123', '/Httpdocs/', 'C:\Test\1TestFile.txt', '1TestFile.txt', 'myusername', 'mypassword');

or :

upload_file('123.123.123.123', 'Httpdocs/', 'C:\Test\1TestFile.txt', '1TestFile.txt', 'myusername', 'mypassword');

Try to get the error with InternetGetLastResponseInfo or GetLastError.

Flob9,
         I get Error 6 (The Handle is Invalid)

Regards
Paul.

Check if InternetConnect succeed, and if not, grab the error code.

"I get Error 6 (The Handle is Invalid)" <<< it must be the hConnect

 

by: flob9Posted on 2009-07-16 at 04:15:58ID: 24868305

also check without the INTERNET_FLAG_PASSIVE

flob9,
         How do I use internetGetLastResponseInfo?

Thanks

My companys FTP policy was blocking the code. At home when tested your code worked fine.
Thanks
Paul.

 

by: flob9Posted on 2009-07-17 at 00:57:26ID: 24876526

something like this :

ErrorNum: Cardinal;
  ErrorBuf: string;
  ErrorLen: Cardinal;
 
[...]
 
hConnect := InternetConnect(hInet, 
                            remote_server, 
                            INTERNET_DEFAULT_FTP_PORT, 
                            user, pass, 
                            INTERNET_SERVICE_FTP, 
                            INTERNET_FLAG_PASSIVE, 
                            0); 
 
if InternetGetLastResponseInfo( Errornum, pChar( ErrorBuf ), ErrorLen ) then
begin 
SetLength( ErrorBuf, ErrorLen );
ShowMessage(ErrorBuf);
end
