I use exactly this constant INTERNET_FLAG_PASSIVE, in the call to InternetConnect function in the step A. <br />
However I get 12026.<br />
<br />
Any assistance in other issues ( ie firewall ? ) that cause this, is kindly appreciated<br />
<br />
Thank you in advance<br />

Well, depending on your (or their!) firewall configuration try to use the active mode then (by not setting INTERNET_FLAG_PASSIVE). Having both sides firewalled IS a problem in FTP.

I use wininet.dll to develop a ( powerbuilder ) code to transfer files using ftp in some specific FTP servers. The process consists of the steps: <br />
<br />
1. Connect to FTP Server<br />
2. Change Remote Directory<br />
3. Upload the file ( using FtpPutFile )<br />
4. Disconnect<br />
<br />
It works fine for the whole FTP connections except one: at this one specific FTP site, I get error 12029 (ERROR_INTERNET_CANNOT_CON<wbr />NECT)<br />
<br />
I would like to under what conditions this error should appear since the process works fine for the rest of FTP connections / sites.<br />
<br />
Thank you in advance<br />

Error 12029 when uploading a text file using Windows FTP Service [wininet.dll]

File sharing is the practice of distributing or providing access to digital media, such as computer programs, multimedia (audio, images and video), documents or electronic books. Common methods of storage, transmission and dispersion include manual sharing utilizing removable media, centralized servers on computer networks, World Wide Web-based hyperlinked documents, distributed peer-to-peer networking (P2P) and cloud-based file syncing.

File Sharing Software

A server is a computer program or a machine that waits for requests from other machines or software (clients) and responds to them. This architecture is called the client–server model. The clients may run on the same computer or may connect to the server over a network. The purpose of a server is to share data or hardware and software resources among clients. Typical computing servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.

Server Software

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.
