C++ I cant upload file to FTP server - c++

Question

I want to upload a file to my FTP server using C++ code and I'm able to FTP my server with FileZilla.
When I run my C++ code, it throws me an output "3" error ( GetLastError() function returned this value to the FtpPutFile() function
#pragma comment (lib,"wininet.lib")
#include <windows.h>
#include <wininet.h> //for uploadFile function
#include <iostream>
using namespace std;
int main()
{
HINTERNET hint, hftp;
hint = InternetOpen("FTP", INTERNET_OPEN_TYPE_PRECONFIG, 0, 0, INTERNET_FLAG_ASYNC);
hftp = InternetConnect(hint, "MY IP ADRESS", INTERNET_DEFAULT_FTP_PORT, "MY NAME", "MY PASS", INTERNET_SERVICE_FTP, 0, 0);
if (!FtpPutFile(hftp, "C://Users//Elliot//Desktop//log.txt", "//log.txt", FTP_TRANSFER_TYPE_BINARY, 0))
{
cout << "FAIL !" << endl;
cout << GetLastError() << endl;
}
else {
cout << "file sended !";
};
InternetCloseHandle(hftp);
InternetCloseHandle(hint);
system("PAUSE");
}
things i have tried :
Changing server ( i made new server but still same result )
Controlling firewall
Running as adminstrator
break points ( the ftpputfile is giving the error )

Answer 1

The error message is clear. File is not there, there is nothing to send. You can easily check the file's path using std::ifstream before continuing with internet functions.
Use FtpSetCurrentDirectory to set a target directory. In this example I used "public_html", maybe your server is different.
#include <windows.h>
#include <wininet.h>
#include <iostream>
#include <string>
#include <fstream>
#pragma comment (lib,"wininet.lib")
using namespace std;
int main()
{
string file = "C:\\path.txt";
string site = "www.site.com";
string user = "username";
string pass = "password";
if (!ifstream(file))
{
cout << "no file\n";
return 0;
}
HINTERNET hint = InternetOpen(0, INTERNET_OPEN_TYPE_PRECONFIG, 0, 0, 0);
HINTERNET hftp = InternetConnect(hint, site.c_str(), INTERNET_DEFAULT_FTP_PORT,
user.c_str(), pass.c_str(), INTERNET_SERVICE_FTP, 0, 0);
if (FtpSetCurrentDirectory(hftp, "public_html"))
{
if (!FtpPutFile(hftp, file.c_str(), "log.txt", FTP_TRANSFER_TYPE_BINARY, 0))
{
cout << "FAIL!" << endl;
cout << GetLastError() << endl;
}
else
{
cout << "file sended !";
}
}
InternetCloseHandle(hftp);
InternetCloseHandle(hint);
return 0;
}
