FTP upload problem

Question

I have made a program to upload to my NAS via FTP protocol. My program runs fine when I try to upload to my web page, but when I enter the IP of my NAS, the following line returns false:

HINTERNET MyhFtpSession = InternetConnect(MyhInternet, "ftp://89.xxx.xxx.xxx/media", INTERNET_DEFAULT_FTP_PORT, "MyUsername", "MyPassword", INTERNET_SERVICE_FTP, 0, 0);

What is the problem? Is the IP line wrong?

Answer 1

First make sure you can actually connect to the site with FileZilla or something.

Also, what happens if you just put the IP address without the leading "ftp"//" and the trailing "/media" ???

Answer 2

From the documentation for InternetConnect() :

Returns a valid handle to the session if the connection is successful, or NULL otherwise. To retrieve extended error information, call GetLastError() . An application can also use InternetGetLastResponseInfo() to determine why access to the service was denied.

In any case, the call is not returning false . Assuming you meant it returns NULL , then you need to call GetLastError() and/or InternetGetLastResponseInfo() to get the information. You can search for the meaning of the error code in the documentation on system error codes . If you post the result here, then we might be able to help you fix your problem.
