    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.
