Value to pass for INTERNET_FLAG_PASSIVE

Value to pass for INTERNET_FLAG_PASSIVE

Value to pass for INTERNET_FLAG_PASSIVE

(OP)
The following is partial code I downloaded from www.davesummers.net/foxprolinks.htm.

DECLARE INTEGER InternetOpen IN wininet;
   STRING sAgent, INTEGER lAccessType, STRING sProxyName,;
   STRING sProxyBypass, STRING  lFlags

DECLARE INTEGER InternetConnect IN wininet.DLL;
   INTEGER hInternetSession,;
   STRING  lcHost,;
   INTEGER nServerPort,;
   STRING  lcUser,;
   STRING  lcPassword,;
   INTEGER lService,;
   INTEGER lFlags,;
   INTEGER lContext

sProxyName = CHR(0)     &&... no proxy
sProxyBypass = CHR(0)   &&... nothing to bypass
lFlags = 0              &&... no flags used

hOpen = InternetOpen (sAgent, 1,;
   sProxyName, sProxyBypass, lFlags)

hftpSession = InternetConnect (hOpen, lcHost,;
   0, lcUser, lcPwd, 1, 0, 0)   &&... 1 = ftp protocol

I have run the code, and it connects to our FTP server fine.
But then I get the error 'Unable to download selected file.'

My question is:

1. What value should be passed to the InterConnect() function to set the INTERNET_FLAG_PASSIVE Flag?
FTP downloads on this particular server must be in Passive mode, not Active.  All Microsoft lists for a value in it's API Flags constants is 0x08000000 for the constant value.  Isn't this a hex value?  I think this is the value I need as Integer.

Thanks in advance for any help, and thanks to Dave Summers for the code to get me to a starting point.

Thanks again to Dave Summers for a utility on his site which has the formula to convert hex to integer.  The value to be passed to InternetConnect for Passive mode is 134217728.  Worked like a charm!  So the command should be:

hftpSession = InternetConnect (hOpen, lcHost, 0, lcUser, lcPwd, 1,134217728, 0).

Hope this helps anyone with the same security problem I had.
