Problem with the FTPPUTFILE WinInet function when using a proxy server 1

[SteveAshdown]

Hi,

I am building an access 2003 VBA application and I am making use of the WinInet dll - specifically the FTP functions.

The functions work fine when I make a direct connection (ie. not via the proxy) to an FTP server and i can put files up to the server with no problems at all.

However, the software we are producing will be required to work in situations where a proxy server is employed.

I have set up a test proxy server locally (ezProxy) and made sure that I can connect to a remote FTP server using my FTP client (File Zilla) via the proxy server. I can also put files up on the remote server and bring then down locally.

However, when trying to FTP files via the proxy server from within my VBA code i am encountering problems. I can make a connection to the Internet and set up a session on the FTP server and I can see what is failing is the FTPPUTFILE function. It just hangs when it when it has been called. I have tried to find information on any changes that need to be in place on the FTPPUTFILE function to cope with the presence of a proxy server but cannot seem to find anything on the microsoft resources or elsewhere.

Help - this one is really bugging me !

Could you post some code, such as the function declarations and the implementation, especially where you invoke the InternetOpen or InternetConnect function and pass the proxy settings?
