WinINet FtpPutFile problem

Hi, I am trying to upload a small file to server using WinINet and FtpPutFile function. The problem is that the FtpPutFile function doesn't work, something has to be wrong somewhere. Here is my code:

Code:

---

#include <windows.h>
#include <iostream>
#include <wininet.h>

using namespace std;

int main() {

    HINTERNET hSession = InternetOpen(0, INTERNET_OPEN_TYPE_PRECONFIG, 0, 0, 0);
    HINTERNET hService = InternetConnect(hSession, "www.server.com", INTERNET_DEFAULT_FTP_PORT, "username", "password", INTERNET_SERVICE_FTP, INTERNET_FLAG_PASSIVE, 0);
    FtpPutFile(hService, "filename.ext", "filename.ext", FTP_TRANSFER_TYPE_BINARY, 0);
    InternetCloseHandle(hService);
    InternetCloseHandle(hSession);

    return 0;
}

---

So, where could be the problem? FtpPutFile returns false.

Thanks in advance,
Anvar.

Your code looks alright. How about providing us with an error number:

Code:

---

int main() {

    HINTERNET hSession = InternetOpen(0, INTERNET_OPEN_TYPE_PRECONFIG, 0, 0, 0);

if (!hSession) printf("InternetOpen: %d", GetLastError());

    HINTERNET hService = InternetConnect(hSession, "www.server.com", INTERNET_DEFAULT_FTP_PORT, "username", "password", INTERNET_SERVICE_FTP, INTERNET_FLAG_PASSIVE, 0);

if (!hService) printf("InternetConnect: %d", GetLastError());

    BOOL bRet = FtpPutFile(hService, "filename.ext", "filename.ext", FTP_TRANSFER_TYPE_BINARY, 0);

if (!bRet) printf("FtpPutFile: %d", GetLastError());

    InternetCloseHandle(hService);
    InternetCloseHandle(hSession);

    return 0;
}

Oh, thanks, I figured it out and it seems that the problem is in the server which doesn't support passive transferring... I replaced the INTERNET_FLAG_PASSIVE with 0 and now it works great! Thank you.
