>If this is the case; then, I need to adjust the Registry automatically for PASV mode on.
Be sure tell us how you did this.

>>Also, if it works, then why am I setting a property in the Registry for something that should be a property in the MSINET.OCX! (So much for the BlackBox theory.)

I also thought it strange that the wininet function declaration passed an argument that is not available as a property in the ITC. Once ITC starts a session with wininet, any subsequent declarations to set Passive could only occur in a seperate session.

I found this in WININET.H (VC98/INCLUDE)

#define INTERNET_REQFLAG_PASSIVE        0x00000010  // FTP: passive-mode connection

But how to work it with ITC is the question! Be sure to share your results!
