Dear Freinds, Im writing a small ftp program that can connect to ftp.trolltech.com and list all files on a list widgets and download it. i can connect to ftp.trolltech.com but i don't know how to list them . Please help me im new in Qt programming. Thank you for your support.

You need an external library and I don't feel to recommend QFtp as it's not maintained anymore. libCURL is probably the standard library in the C/C++ world (and probably beyond). You can use a cpp wrapper like curlpp if you don't like the aftertaste C leaves in your mouth. This example ( source ) will download the list of files from ftp://ftp.funet.fi/ and save it in a file called ftp-list #include <stdio.h> #include <curl/curl.h> static size_t write_response(void *ptr, size_t size, size_t nmemb, void *data) { FILE *writehere = (FILE *)data; return fwrite(ptr, size, nmemb, writehere); } #define FTPBODY "ftp-list" #define FTPHEADERS "ftp-responses" int main(void) { CURL *curl; CURLcode res; FILE *ftpfile; FILE *respfile; /* local file name to store the file as */ ftpfile = fopen(FTPBODY, "wb"); /* b is binary, needed on win32 */ /* local file name to store the FTP server's response lines in */ respfile = fopen(FTPHEADERS, "wb"); /* b is binary, needed on win32 */ curl = curl_easy_init(); if(curl) { /* Get a file listing from sunet */ curl_easy_setopt(curl, CURLOPT_URL, "ftp://ftp.funet.fi/"); curl_easy_setopt(curl, CURLOPT_WRITEDATA, ftpfile); /* If you intend to use this on windows with a libcurl DLL, you must use CURLOPT_WRITEFUNCTION as well */ curl_easy_setopt(curl, CURLOPT_HEADERFUNCTION, write_response); curl_easy_setopt(curl, CURLOPT_HEADERDATA, respfile); res = curl_easy_perform(curl); /* Check for errors */ if(res != CURLE_OK) fprintf(stderr, "curl_easy_perform() failed: %s\n", curl_easy_strerror(res)); /* always cleanup */ curl_easy_cleanup(curl); } fclose(ftpfile); /* close the local file */ fclose(respfile); /* close the response file */ return 0; }
